With the continuous emergence of high-rise buildings, problems such as high wind load and high pumping have brought great difficulties to the construction of high-rise structures. Among them, the construction of concrete placing boom is a big problem.

The fine-stone concrete pump is a special type of concrete pump. This concrete pump is widely used in floor heating projects and floor construction, so it is welcomed by the majority of construction parties. So on the construction site, what are the pumping requirements of the fine stone concrete pump? Now let’s take a closer look.

In the concrete pumping construction operation, once the pipe blockage occurs, the slight blockage can be dredged by repeated forward and reverse pumps and tapping with a wooden hammer. Serious blockage may need to be removed and replaced. Therefore, prevention of pipe blockage is particularly important.

Causes of blocked pipes
With the rapid development of building construction, concrete pumping equipment concrete placing boom has been widely used by construction units. However, in the concrete pouring operation, due to improper use, the phenomenon of equipment pipe blockage occurs from time to time, which not only affects the project progress, but also directly affects the project quality.

The hydraulic concrete placing boom is a kind of terminal equipment used in conjunction with the concrete pump. It is suitable for the construction of high-rise buildings and large-area concrete pouring projects. It can easily and efficiently transport the concrete to the pouring operation point, realize continuous and uniform distribution, and reduce construction costs. Improve the quality of concrete pouring and construction progress.

It is inevitable that there will be some failures when using backhoe loader to be busy for construction. Today we are explaining what is the reason for the failure of the boom.

The extensive use of backhoe loader not only saves man power and material resources, but also greatly improves work efficiency. Let’s take a look at the working principle of backhoe loader:

1 The main personnel involved in the concrete placing booms installation and disassembly must be familiar with the performance structure and characteristics of the cloth machine, skilled in technology, and have the ability to troubleshoot.
2 In the process of concrete distributor assembly and disassembly, a special person must be responsible for unified command.
3 The placing boom assembly and disassembly site should be cleaned up, and non-workers are prohibited from entering.

With the development of science and technology, the continuous expansion of the construction field, the continuous improvement of engineering construction quality requirements and the need for environmentally friendly construction, various types of wet spraying machines have emerged, including small concrete wet spraying machines, vehicle-mounted concrete wet spraying machines, and It is suitable for wet spraying concrete equipment such as concrete wet spraying trolley for large-scale projects.

In recent years, the emergence of wet spraying trolleys has solved many inconveniences in the construction process of today's projects, and has improved the efficiency of tunnel construction, coal mine construction, and slope sprayed concrete construction. The progress of China's construction machinery and equipment is largely attributed to the reform and opening up. During this period, front-end technology and foreign-funded enterprises were successively introduced.

Daily inspection of concrete placing booms.
Check whether the electrical system is working properly before operation.
Check whether the oil level of the oil tank is lower than half of the oil tank and whether the hydraulic oil is emulsified. Check whether there is leakage of hydraulic components.
Check whether the rotation direction of the oil pump is correct.
Check whether the metal structural parts are cracked, welded, twisted or deformed.

How to be lifted / jacked-up to the tower hydraulic self-climbing concrete placing booms ?

1. Before using the concrete distributor concrete placing boom, the horizontal support at 2 meters of the tower must be adjusted by the screw to make the roller tightly against the four walls.

The pumped concrete should be designed in strict accordance with the regulations, the slump should be strictly controlled, and the following principles should be followed. (1) The ratio of the large particle size of the coarse aggregate to the diameter of the conveying pipe should be: when the pumping height is below 50 m, the

Leakage caused by imperfect sealing of the pipeline will affect the quality of concrete pouring on the one hand, and reduce the slump of the concrete and the loss of pumping pressure on the other hand, which will lead to the blockage of the pipeline. The pipeline joint is not tightly sealed, the pipe clamp is loose or the sealing ring is damaged, causing slurry leakage.
