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 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.

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.

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;
