In the construction site, all kinds of machinery and equipment are overwhelmed, and the safe use of concrete placing boom machine machinery and equipment is particularly important.

Concrete pumps play the role of transporters in large-scale concrete projects such as high-rise buildings, highways, and overpasses, so they are very important. For concrete pumps, the correct and safe use is equally important. In the daily operation process, how should we use the concrete pump correctly?

The concrete pump cutting ring mainly cooperates with the rubber spring, and the gap is automatically compensated by the rubber spring and the pressure self-balance, so that the floating cutting ring has a self-sealing effect, thereby increasing the conveying pressure of the S-pipe valve. However, when the concrete pump is used for a long time, the cutting ring of the concrete pump is prone to wear.

Concrete pump has now become an indispensable member of engineering construction. In addition to the promotion of urban and rural construction, its own advantages are also very obvious, reducing labor force, shortening construction period, and improving project progress efficiency. The correct use of the concrete pump can not only improve the work efficiency, but also avoid the blockage of the concrete pump. Common concrete pump easily blocked positions and elimination methods are as follows:

Requirements for concrete slump in fine stone concrete pumping
When the concrete with a slump of 10-15 cm is dumped into the hopper, its surface is easily broken; when the slump is less than 10 cm, the concrete is completely broken after tilting, and has a serrated edge, which breaks vertically. into thick blocks;

To improve the pumpability of concrete, it is necessary to increase the amount of cement, use a larger water-cement ratio and sand ratio, and use a stricter aggregate gradation, which means an increase in cost or a decrease in quality. A more economical and effective way is to use admixtures to improve the pumpability of concrete. There are many types of additives, among which the admixtures that can improve the pumpability of concrete include air-entraining agents,
