Nowadays, concrete pumps are used more and more in the construction of rural cities. Concrete pumps can be seen everywhere during construction. Many customers report that concrete pump piping is a big problem. Often, engineering pumps are delayed due to concrete pump piping. Then concrete How does the pump pipe down? This is a problem that many construction parties are very concerned about.
Experts point out that in the construction, the pipe laying of concrete pumps is very important. If the pipe is not adhered to certain operating rules due to some reasons, it is likely to cause the occurrence of pipe plugging, which will cause frequent construction incidents. So how does the concrete pump pipe down during construction? It is recommended to follow the following key steps:
① The lower end of the inclined pipe is connected to a horizontal pipe with a total length equivalent to more than 5 times the length of the skewed pipe, or a curved pipe of equivalent length is used to add the resistance at the lower part of the inclined pipe.
② At the end of the inclined pipe, connect a piece of pipe that is tilted upward.
③ Install an exhaust valve on the bent pipe at the upper end of the inclined pipe, and use it to exhaust the air in the pipe when the pump is turned on again after the pumping is interrupted.
④If restricted by site conditions, once there is not enough space to arrange the horizontal pipe at the front of the downwardly skewed pipe section, the hose can be replaced with a hose, elbow or circular pipe to increase the frictional resistance and block the concrete in the downwardly skewed pipe section. Artesian.
The concrete pump was a kind of mechanical equipment used by many construction parties at that time. How did the concrete pump lay down the pipes during the operation? After the above introduction, I trust the majority of users to understand this problem.
