The Role of Stabilized Soil in Construction

Stabilized soil plays an important role in construction, and it is mainly used to enhance and improve the mechanical properties of soil in order to meet the requirements of engineering projects. The following are several main functions of stabilized soil in construction:

1. Provide bearing capacity: Stabilized soil can increase the strength and stability of the soil, providing better bearing capacity to support heavy loads of buildings and infrastructure. It reduces subsidence and deformation of the soil, ensuring that the soil remains stable under load. Stabilized soil is underneath the concrete. And there are many plants to produce stabilized soil and concrete.  You can find then from top manufacturer.

2. Prevent infiltration and erosion: Stabilized soil can reduce the permeability of the soil and prevent the infiltration of moisture and chemicals into the underground structure, thereby protecting the stability and durability of the building. In addition, stabilized soil can also reduce soil erosion and prevent soil from being eroded by water flow and wind erosion.

3. Improve the engineering performance of soil: stabilized soil can improve the engineering performance of soil, including rigidity, plasticity, compressive resistance, shear strength, etc. By adding materials (such as cement, lime, etc.) or changing the proportion and structure of the soil, stabilized soil can increase the compressive and shear strength of the soil and improve the engineering stability of the soil.

4. Reduce settlement and deformation: stabilized soil can reduce soil settlement and deformation, and maintain the level and verticality of buildings. By increasing the stability and compactness of the soil, stabilized soil can control the settlement and expansion of the soil, reduce the shrinkage of the soil and the deformation caused by the swelling soil.

5. Provide construction materials: Stabilized soil can be used as construction materials for filling and leveling the ground surface, building roads, dams, slopes, etc. It can provide a strong, reliable foundation on which to build other structures.

In general, the role of stabilized soil in construction is to enhance the mechanical properties of the soil, improve the bearing capacity of the soil, prevent infiltration and erosion, improve the engineering performance of the soil, reduce settlement and deformation, and use it as a construction material. It plays an important role in both civil engineering and construction projects. If you want to know how to produce the stabilized soil, clink Luton construction machinery.

How Many Meters Can Concrete Be Pumped By Ground Pump

1.How many meters can concrete be pumped by ground pump?
The answer is mainly determined by the specification of the ground pump. If it is a pump with output capacity of 60m3/h, the answer is about 80m to 100m height. While if it is a pump with 80cm3/h output capacity, it is about 100m to 120m height.

32m concrete boom pump on site

2.Theoretically, 60m3/h and 80m3/h are both the output capacities under ideal condition. The actual number is less than the theoretical data. Meanwhile, there are so many kinds of concrete ground pumps in the market, the characteristics of different products from different brands are various in certain area. So, the pumping heights are also different.

3.Cautions of choosing ground pump

  • Get to know the pouring requirement. The construction requirement of different concrete types is different, so we should choose ground pump referent to the construction requirements. In this way to make the performance of the pump up to the extreme.
  • Choose proper ground pump according to the type of construction project. If the utilization is low and can not meet the requirement, it may cause some loss to the ground pump.
  • Choosing pump should also referent to the practicality of construction. The required pumping height is higher, the big model we should choose.
  • Select suitable place to conduct pumping job according to the working amount. If the construction amount is big, we should choose a spacious place and choose two or three pumps to shorten working period efficiently. So, for choosing ground pump, there are many cautions to pay attention to. Hope you find your ideal pump soon.

Brief Introduction to Working Principle of Concrete Pumping System

Concrete pump system is composed of hopper, pumping system, hydraulic system, cleaning system, electrical system, motor, walking chassis, etc.

The pumping mechanism consists of two main oil cylinder, water tank, reversing device, two concrete cylinders, concrete hopper, distribution valve (S-shaped valve), swing arm, two swing oil cylinders and discharge port.

The concrete pistons are respectively connected with the piston rods of the main oil cylinder.Under the action of the hydraulic oil of the main oil cylinder, they reciprocate continuously. One cylinder advances, and the other cylinder retreats.

The concrete cylinder outlet is connected to the hopper. One end of the S-shaped distribution valve is connected to the discharge port, and the other end can be connected with the swing arm through the spline shaft, which can swing left and right under the action of the swing cylinder.

When pumping concrete, under the action of the main oil cylinder, the concrete piston 1 moves forward, and the concrete piston 2 retreats. At the same time, under the action of the swing oil cylinder, the S valve is connected to the concrete cylinder 1, and the concrete in the concrete cylinder 1 was pump out the discharge port through the S-shaped valve.

At this time, the concrete cylinder 2 is connected with the hopper. During the backward movement of the concrete piston 2, the concrete in the hopper is sucked into the concrete cylinder 2.

When the concrete piston 2 retreats to the end of the stroke, the reversing device in the water tank is triggered. The main oil cylinder 1 is reversed, and the swinging oil cylinder is reversed.

So that the s-shaped valve is connected to the concrete cylinder 2, and the concrete cylinder 1 is connected to the hopper. Piston 1 moves backwards and piston 2 moves forward. A new working period begins, so as to achieve continuous pumping.

When the pump is working at the reversed mode, the concrete cylinder in the suction stroke is connected with the S valve, and the concrete cylinder in the push stroke is connected with the hopper, so that the concrete in the pipeline is drawn back to the hopper.

The pumping system completes the suction and discharge of concrete through the conversion of the s-shaped distribution valve. Therefore, the s-shaped distribution valve is a key component in the concrete pump, and its type will directly affect the performance of the whole pump.

PLC programming

Next, this article will briefly introduce the application of PLC programmer in concrete pump by taking Siemens S7-200 Smart PLC as an example.

The program development of S7-200 SMART PLC mainly includes motor start-up program, running instruction, proximity switch function, etc.

Motor start

This is the program for starting and stopping the motor. I0.0 is the motor starting signal. By detecting the pulse signal, M0.0 is set, and then conduct the star-type start. At the same time, the timer T37 runs. After 8S, the star-type start turns to the triangle-type. So far, the motor start is completed.

Running instructions

This is the operation instruction of the positive pump and the reverse pump. M3.0 is the middle flag bit that is triggered by the far and near empty positive pump, which drives the Q0.2 positive pump indication. M3.1 is the middle flag bit that triggers the far and near empty reverse pump, which drives the Q0.3 reverse pump indication.

Proximity switch to realize positive and negative pump

This part uses two sensors (proximity switches) I1.0 and I1.1 to detect the opening and closing of the main oil cylinder, and realize the alternate operation of the positive and negative pumps.
The main oil cylinder consists of two sets of hydraulic cylinders and two sets of material cylinders. The main working principle is: the No. 1 hydraulic cylinder drives the No. 1 material cylinder to suck material from the hopper when the pump is running. When the sensor detects that the main oil cylinder is in place, the swing cylinder is controlled by the program to swing to the No. 1 material cylinder, and then No. 1 hydraulic cylinder is used. The cylinder drives the No. 1 material cylinder to push the material, and the material in the No. 1 material cylinder is pumped out through the s valve.

How to Choose a Suitable Asphalt Mixing Plant

Asphalt mixing equipment is a complete set of equipment used for mass production of asphalt mixture, and is necessary equipment for building expressways, grade highways, municipal roads, airports, ports, etc. Generally, the model and production capacity of the mixing equipment are determined according to the working conditions, construction requirements, quantities and construction period of the asphalt pavement.

Asphalt mixing equipment is divided into forced intermittent type and continuous type according to the mixing process; It is divided into fixed type and mobile type according to the mode of transportation. Luton Group can provide you more detailed contents.

Stationary Type or Mobile Type, Which one

If the construction site is fixed, select stationary type plant , otherwise select mobile type plant; If the quantity of work at the same construction site is small and the site is frequently transferred, select mobile type, otherwise select stationary type plant.

stationary asphalt mixing plant

Forced Batch Asphalt Plant or Continuous Asphalt Plant, Which one

The forced batch type plant host system is complete, and the single bucket scale is used for batch hot aggregate measurement; The continuous asphalt plant main machine has no screening system and no separate mixing system. The belt weigher is used for continuous cold aggregate measurement. Therefore, its structure is featured by simple structure, few components and convenient installation and maintenance. However, the requirements for the stability of aggregate supply are high.

bitumen-batch-plant

If the aggregate source, classification quality, moisture content and dust rate are stable, the continuous type can be selected; otherwise, the forced batch type is recommended;
If higher buildings are allowed to be built on the mixing station site, select “forced intermittent type” and “continuous type” if not allowed;

The owner shall first consider the product procurement cost and maintenance and operation cost. The continuous procurement cost and maintenance and operation cost are relatively low, but the requirements for the specification grade and supply stability of aggregates are very high;

When the recycled materials are added in a forced batch plant, an additional recycled system must be added, and the added proportion of recycled materials is usually not more than 30-50%; Continuous type usually has recycling function, and the proportion of recycled materials can usually reach 50%.

Does the Asphalt Plant need to Be Equipped with a Recycling System

The government requires that old materials must be recycled, and as the basic condition for the owner to bid for the pavement works, the recycling system needs to be configured;
The owner considers that it needs to be used for pavement maintenance and construction now or in the future and needs to configure a recycling system;

asphalt recycling equipment

The owner considers the integrity and environmental protection of the mixing equipment function and needs to configure the recycling system to meet the requirements of more pavement construction;

There are two options for configuring the recycling system. First, you can choose the batch asphalt plant, but you need to configure a recycling system; second, you can choose the continuous asphalt plant without configuring additional recycling system.

How Long Does A Fixed Concrete Pump Last

Why Choose a Small Mobile Asphalt Plant

Asphalt mixing plant plays an important role in batch asphalt production. The structure of this equipment is simple and reasonable, and it meets the processing requirements of modern industry. Therefore, many industrial places will complete the production of asphalt through asphalt mixing plant. Now, in order to enable different industries to operate asphalt hot mix plants efficiently, the classification of equipment is also increasing. More and more asphalt mixing plants appear in the vision of the construction party and investors, such as forced batching asphalt plants, double drum asphalt plants, reclaimed asphalt plants, small asphalt plants and portable asphalt mix plants.

Please click on Luton Asphalt Plant to learn the detailed types of asphalt plant.

At present, mobile and stationary asphalt mixing equipment are widely used. However, the stationary asphalt equipment can only complete the asphalt production and processing process at the designated position during operation, so it is far less flexible than the mobile asphalt station. In the following, the advantages of the mobile asphalt mixing plant will be emphatically discussed by taking the small mobile type asphalt mix plant for an example.

mini-small-asphalt-drum-hot-mix-plant

Features of small mobile hot mix asphalt plants are described as the following paragraph:

The small mobile asphalt plant is fast to transport from one site to another because of high portability, for example, fillers silo and mixing pot are equipped with tires. Of course, It also shortens the installation time, save some unnecessary labor cost and improve the efficiency of the whole team due to its simple structure.

The small mobile hot mix asphalt plants can drive for a long distance and doesn’t an extra trailer car, which saves the expense of hiring a truck man and a flat-bed trailer. Also, it is very easy to maintain and repair due to its modular design, which doesn’t need to cost a lot of manpower. What’s more, it doesn’t contain the mixing tower and vibrating screen, so its maintenance cost is also very low.

mini-mobile-hot-mix-plant

Compared with the stationary asphalt mix plant, a big part of that difference is that the most of asphalt mobile plants hardly lay the foundation. There is only one requirement that as long as the construction site is flat enough, it can work normally.

The small portable asphalt mixing plants are suitable for medium and small-size projects especially the special construction sites. For example, they can pass through the narrow road and reach the mountainous regions because of small size and high flexibility.

The small mobile asphalt plants are featured by fully automatic control and advanced control panel. Therefore it’s easy and smooth to operate even if a novice can master them in a short time, too. Meanwhile, the fully automatic control can save time and improve working efficiency.

LUTON small portable asphalt plant is fitted with various dust filters such as cyclone filter, gravity water filter and bag-house filter. Each one has a good dust collecting effect. Therefore it is environmental-friendly.

 

How to Maintain the Concrete Boom Pump

The concrete boom pump, also called the concrete pump truck, is a machine which uses the pressure to convey concrete continuously along the pipe. By and large, it consists of the pump body and the delivery pipe. And to be more specific, the concrete pump truck is comprised of the pump body installed on an automobile chassis, the elastic placing boom and a truck. ( If you are also interested in any type of concrete pump, welcome to join me to discuss more details about it together.)

65-meter-long-boom-pump-truck

Maintaining and using a concrete boom pump is at a relatively high cost. Every part of the concrete boom pump is very important, and various faults will occur during the operation. The boom of the concrete boom pump is the core part, which supports the transmission pipeline and plays a vital role in the transportation of concrete. Therefore, the daily maintenance of the boom is particularly important. The relevant maintenance measures are shown as below:

  • Regularly lubricate and oil each lubricating point of the boom, and use the special grease for the boom of the pump truck to ensure its good working performance.
  • Bolt fasteners, nuts, etc. are regularly reinforced by torque wrench, and reinforced according to the torque of each bolt. If the bolts and nuts are to be replaced, please replace them according to the same specifications and models, including the strength grade of the bolts and nuts.
  • The balance valve of boom cylinder is easy to be blocked due to excessive hydraulic oil impurities. Therefore, the replacement of hydraulic oil of the pump truck should also follow the normal maintenance process of the pump truck.
  • Please use the original pump pipe. Because the material quality of many external pump pipes is not up to standard, the thickness of the pump pipe can only be increased to improve its anti-wear ability. However, the weight of the pump pipe with the same length will certainly increase, which will cause additional load on the boom and affect the service life of the boom. Therefore, try to use the original pump pipe.
  • If any problem is found, it shall be handled immediately. At present, some minor cracks of the boom can still be repaired. However, due to the steel used for the boom and the special welding process, the repair work should also be handled by a regular repair shop or a pump truck brand company.

32m concrete boom pump on site

In general, the boom maintenance of the concrete boom pump is very important. In case of an accident, the consequences will be very serious, and the later maintenance costs will be very high. Therefore, the pump truck boom should be checked regularly to ensure construction safety.

Factors that Affect the Price of Concrete Boom Pump

Concrete Boom Pump is a kind of high-efficient and automatic concrete placing equipment widely used as basic construction machinery. It is an ideal investment option if you want to join in the construction machinery industry.

LUTON Concrete Pump

You know, for the advanced design, complex production process, easy operation and convenient maintenance, the price of concrete boom pump is usually higher than of other pumps.

But how these factors affect the price? Or why it is expensive than other types of concrete pump products? Here reveals the details beneath the fact of concrete boom pump price.

( For more concrete pump products, you can click on https://ltconcretepump.com/ )

Raw Materials

As an important fact of product cost, raw material price affects the whole price of concrete boom pump.

High-quality raw material ( such as steel material, alloy material and so on ) is the basic assurance of high-performance concrete boom pump. Of course, the price is relative higher, which cause the basic price of the whole pump equipment.

Otherwise, it does not stay immutable, but fluctuates following the market. It is another aspect of affecting the price of concrete boom pump. Usually, the price will decrease when the
supply is beyond the demand. Conversely, it will increase when the supply can’t meet the demand.

Configurations

Configuration is another important fact that influences the actual price of boom pump. We all know, there are many Components in a complex concrete boom pump system. The brand, quality, performance, service life of these components are the most crucial aspect affects the price, such as the PLC of Siemens, the relay of Schneider, the controller of Omron, the main oil pump of Kawasaki.

Just like the both sides of a coin, these parts from world famous brands, in one hand, ensures the high working performance of the concrete boom pump, but in the other hand, it leads the
high price.

Products Types

Different types leads to various concrete boom pump price. That is also an important influence.

The longer the concrete boom is, the higher the price is. That is certainly because that the longer concrete boom means the more advanced design process, the more complex producing
technology, and the longer manufacturing period. So it means the production cost is more and the price is higher.

38m concrete boom pump

Usually, concrete boom pumps are classified according to the length of the boom. The length of boom is designed differently by different manufacturers.

Generally speaking, there are three types of concrete boom pump, the short boom pump, the long boom pump and the super long boom pump. The short boom pumps refer to the booms length under 30 meters.

The boom length between 31m to 47m is called the long boom. And the super long boom means the boom length beyond 50 meters.

Do you know the longest concrete boom pump in the world? 101-meter concrete boom pump truck from Zoomlion is the longest concrete boom pump all over the world. Its price is up to million dollars.

Also, there are other classifying methods according to the produce capacity, the pumping pressure, the folding section etc. NO matter which methods, the principle does not change. That is the larger scale, the more complex design and the more components including, the higher the price is.

Brands

Manufacturers and brands may be the commonly concerned facts for investors. The prices of concrete boom pump various according to the products quality and around-sale service. The more famous brands and the more thoughtful service point to the higher prices.

That is also like two sides of a coin. On one side, famous brands ensure the high produce quality and good working performance. On the other side, the brand effect sometimes leads to an inflated price. That is not what customers need.

Actually, a suitable choice is usually wiser than the expensive option. Hope my opinion can help you get more about the affections ofthe concrete boom pump price. …Read more.
