Speaking of cement drainage pipes, I believe that we will not be unfamiliar. It is mainly used in underground construction in urban construction and has a drainage and sewage effect. Because its application is mainly concentrated underground, in order to reduce the occurrence of rework in the future, it is very important to pay attention to the construction, especially some construction precautions. So what do these precautions involve? Let's take a look with the editor of Guangzhou Wanxin Cement Pipe Manufacturer.
The resettlement of the cement drainage pipe system should be comprehensively planned to try to:
① The channel of the cement drainage pipe should be at a low level of the control area, in order to drain as much as possible by self-flow.
② According to the terrain, the drainage area should be divided into high, medium, and low-level slices to achieve high water and high drainage, low water and low drainage, self-priming and auxiliary drainage.
③ The exit of the cement drainage pipe trunk ditch should be selected at the place where the water level in the drainage area is low and the river bed is relatively stable.
④ The lower drainage channel shall be arranged in a good condition for the upper drainage channel, and the trunk channel shall be arranged as straight as possible. In addition, the cement drainage pipe ditch shall be set aside from the poor soil area to save engineering costs and make drainage safe and timely.
⑤ In drainage areas that are invaded by external water, interception ditches or flood ditches should be installed so that external surface water and groundwater can be directly introduced into drainage cement drainage pipes or drainage areas.
