Shotcrete machine is the core equipment in shotcrete construction, and is widely used in related shotcrete support projects such as construction, municipal administration, railway and highway tunnels, foundation pits, mines, and slopes.

Concrete shotcrete machine refers to the professional shotcrete support equipment that uses compressed air to form a suspended air flow of concrete in a certain proportion, and sprays it onto the surface to be applied to form a dense concrete layer to achieve the purpose of support.

Since the 1960s, western developed countries have begun to implement wet spray technology, and various wet spray machines have been developed and put into use one after another. At present, in some western countries, wet spraying machine has become the main equipment for shotcrete operation, and the application rate in many countries reaches more than 80%. In China, wet spraying technology started late, and the market was still blank until the early 1990s.

Concrete shotcrete machine is a kind of shotcrete support equipment widely used in underground engineering, geotechnical engineering, municipal engineering and other fields. Concrete shotcrete machine is generally divided into two categories: concrete dry shotcrete machine (also known as dry shotcrete machine) and concrete wet shotcrete machine (also known as wet shotcrete machine). The concrete dry spraying machine is a method of mixing cement, sand and stones evenly in a dry state.

With the continuous development of tunnel construction technology, the requirements of tunnel engineering quality, operation safety, occupational health and other aspects have been continuously improved. In each process of tunnel construction, mechanized equipment has gradually been used instead of manual labor. Tunnel concrete wet spraying machine has become the mainstream of shotcrete operation. equipment.

The whole operation includes the whole process from power generation to termination on the excavation surface, and the whole process from the unloading of concrete from the tanker to the termination on the excavation surface.

Learn how airflow is used in a self-loading mixer?
Mixers are used more and more widely in the chemical industry. Many chemical productions use more or less mixing operations. Today, let's briefly look at how self-feeding mixers perform airflow mixing?

The small concrete mixer has a wide range of use and flexible operation. It has good professional function and cluttered structure, but it has high mixing strength, strong mixing processing expertise and good processing effect. Let's briefly understand the ductility of the mixer truck: , The concrete mixer has a strong single-machine mixing performance, and is used in the processing and application of the production line to improve the processing power of the complete set of equipment.

When starting the car in winter, the oil temperature will be too low due to insufficient preheating. When the oil and oil seal have not reached the working temperature, the automatic feeding mixer needs to stop the tank and run at an idle speed for 10 to 20 minutes during the whole starting process. After the oil temperature reaches the normal state, the tank transfer work will be started.

How to adapt to construction and prolong the service life in harsh environments is the concern of every wet sprayer user. Saintyol DAWIN Machinery will take you into the maintenance of wet spraying machine. Based on years of production experience, the summary is as follows:

What preparations need to be done to improve the working efficiency of the wet concrete sprayer

With the emergence of the wet spraying trolley, it not only solves the problem that traditional small wet spraying machines cannot meet the insufficiency of concrete spraying in long tunnels, but also improves the working environment of tunnel construction personnel, and reduces the consumption of concrete. Concrete wet spraying trolley, also known as concrete wet spraying manipulator, concrete spraying manipulator, is widely used in railways, highway tunnels, slopes, water conservancy

What aspects should be paid attention to when placing concrete?
Whether the concrete pouring is reasonable and correct is seriously related to the construction quality of the whole project. Therefore, on the issue of pouring, there should be no deviation from any engineering construction unit. For such an important project construction link, what requirements should we meet when it is completed, and what aspects should our builders pay special attention to?

a) Remove the water tank cover of the wet spray trolley, open the valve at the bottom of the water tank, and drain the water in the water tank;

Most of the small concrete pumps are in the form of double cylinders. The two hydraulic cylinders drive the pistons of the two conveying cylinders to work alternately, which not only makes the conveying of concrete more stable and continuous, but also greatly increases the displacement. Its working principle varies according to the distribution valve and control method, but the main difference is still reflected in the realization of the reversing action.

The fine stone concrete pump adopts a hydraulic system. The concrete pump has the characteristics of long concrete cylinder stroke, high vertical distance for conveying concrete, and long distance for horizontal conveying concrete. The fine stone concrete delivery pump, ground pump and drag pump all adopt a continuous lubrication system, which solves the damage to the fine stone concrete pump due to lack of lubrication during the process of conveying concrete.

Concrete pump is mainly composed of truck chassis and power take-off device of pump truck, concrete pump, distribution device, outrigger device, hydraulic system and cleaning system. Since there are so many devices, which device plays the key role? Qingke Heavy Industry has summarized the following points through years of experience:

With the development of rural areas, many people turn their attention to rural construction, because buying a concrete mixing pump is likely to be the beginning of getting rich. When choosing to buy a mixing pump, some people buy whichever is cheaper in order to maximize profits.

With the construction of various mine roadways, railway and highway tunnels, water conservancy culverts, and various underground projects in the country, the internationally advanced support method of shotcrete support is widely used. Concrete sprayer is the main equipment for this operation. There are three major problems with dry sprayers: ① large dust, ② more rebound, and ③ poor quality. The country is now vigorously promoting wet wet spraying, which has the advantages of low dust,

Precautions for pump operation:
1. The place where the pump truck is in place is flat and solid, and there are no obstacles around. Pump trucks must not be parked on slopes. The parking position meets the needs of pouring, and does not obstruct each other with other on-site machinery, which affects the construction progress and the safety of construction workers.

As a kind of concrete conveying equipment developed for the characteristics of floor heating construction, the fine stone concrete pump is widely expected by construction units because of its large-area and high-efficiency construction in the filling layer or mortar filling layer of the floor heating project. So why does the fine stone concrete pump work so well? Now we introduce the characteristics of the major components of the fine stone concrete pump as follows.

The operator of the concrete mixing pump should check whether the thickness of the brake pads of the braking system is too thin. If they are worn to a certain extent, they must be replaced. It should be noted that if the brake drum wears too much, even if the thickness of the brake pads is full, it may cause The brake camshaft travel is too long, causing the brake shoes to die. Also check to see if the brake camshaft grease passages are not blocked.

The general concrete spraying process is divided into dry spraying and wet spraying. For dry sprayers and small wet sprayers used for manual manual operation, the amount of rebound and drop of the spray is still very easy to control. If there is a large amount of falling, it is the problem of the ratio of sprayed concrete and the accelerator. For large wet spraying machines (manipulators), there are many reasons for falling sprayed concrete.

Advantages of installing an air compressor: Saintyol DAWIN 3016B concrete wet spray trolley is equipped with a 75kw air compressor. There is no need to connect additional air sources on the construction site. It is fast and convenient to transfer and move vehicles. Greening, slope protection and other projects provide a strong guarantee, high efficiency, good stability, fast movement and other advantages, is a good helper for tunnel construction.

Saintyol DAWIN small wet spraying machine has high construction efficiency, low dust concentration in shotcrete operation, low rebound rate, accurate water-cement ratio control, fully hydrated cement, high strength of shotcrete, great cost savings, no dust generation, In turn, the impact on workers and the environment is not large, and it is suitable for various working environments.

Most of the fine stone concrete pumps use a hydraulic system. The piston rod in the main oil cylinder generates mechanical pressure under the power. When the piston retracts, it generates self-priming in the conveying cylinder. The concrete in the hopper is under the action of atmospheric pressure and the boost of the stirring blade. Under the action, it is sucked into the conveying cylinder through the suction port of the slide valve.

Mixing pumps are often used in the current construction of new rural areas. They can not only perform on-site mixing, but also transport concrete. It is suitable for reservoir construction, residential building construction, tunnel engineering, and water conservancy engineering construction projects. Many people are very concerned about the operating conditions of concrete pumps when they are in use, but few people pay attention to the correct way
