The concrete pump is a special type of concrete pump, which is widely used in floor heating projects and floor construction. As a result, it has been welcomed by the vast construction parties. Today, the editor of Shanjian Heavy Industry will talk about the detailed rules and points of how the concrete pump should be operated. Let's take a look!

1. Preparation before pumping

Before pumping the concrete pump, pay attention to the concrete hydraulic gauge and the working status of each part. Normally, it is prone to blockage at the outlet of the concrete conveying pump. In case of blockage, the pump should be stopped and reversed to make the blocked concrete. Reflux, wait until it is evenly stirred before pumping. If no effect is seen, stop the pump to remove the infarction.

2. The main points of pumping

During the pumping process, the concrete should be continuously supplied. If the material cannot be supplied continuously, the pumping speed of the concrete can be slowed down. In addition, when the pump is out of joint, the pump cannot be stopped, but the concrete should be let every 4-5 minutes. The pump stops rotating forward and backward. In order to avoid agglomeration or precipitation of the mixed material in the pipeline, if the pumping stops for more than 45 minutes, it should be cleaned and pumped again.

When pumping concrete, keep a certain amount of concrete in the hopper, so as to prevent air from entering the hopper, forming a backflow of concrete and forming an obstruction. If this problem occurs, the pump needs to be reversed to return the concrete to the hopper, and then stop normal pumping when the air comes in.

It is worth noting that during the pumping process, the water in the washing tank should be changed every 2 hours, and the stroke of the pump cylinder should be checked at the same time. If there is any change, it can be adjusted in time. In addition, in order to reduce the uneven wear of the inner wall of the cylinder, it is best Start a long stroke, and stop short-distance pumping of concrete only when starting and when the concrete slump is small.

3. The main points of vertical pumping

When conveying concrete vertically upwards, the water hammer will cause the concrete to flow backwards and the conveying efficiency will drop. The higher the conveying pipe, the more obvious the phenomenon. To solve this problem, the correct way to deal with this problem is to set a section of 10 meters between the pump and the vertical pipe. The above-mentioned degree pipes can offset the impact of concrete falling impact; and the concrete pump should have a stop valve near the discharge port.

In addition, when constructing under high temperature, care should be taken to cover up two layers of wet grass curtains on the protective pipe to prevent sunlight, and stop spraying water regularly to avoid pipeline blockages.
