1. The principle of overflow well discharge method: the sewage is mainly discharged into the municipal sewage pipe through the overflow well, and the pump is used as a supplement to remove the accumulated water in the overflow well and the upstream sewage pipe. The flow should be confirmed by discharging all accumulated water within 30min. In order to reduce the operation cost, the sewage pump can be started before the peak water consumption every day to drain the accumulated water in the overflow well and the upstream pipeline. This can not only prevent sewage from staying in the pipeline for a long time and forming siltation, but also make the ponding pipe section often washed, which is conducive to pipeline ventilation and the removal of harmful gases in the pipeline.

The cause of cracks on the surface of cement pipe. The cracks on the surface of cement pipe are mostly caused by folding, and the key can be divided into two categories: one is caused by the evaporation and hardening of the water on the surface of cement pipe during rigid concrete pouring. Generally, the average external temperature of cement pipe during rigid concrete pouring is high, while the air humidity in the air is low, so the surface will volatilize and dry, but the interior is still plastic, This causes cracks. The other is caused by the temperature difference between the inside and outside of the concrete caused by the water cement ratio when the cement pipe is hardened. For deeper cement pipes, the foundation will continue to settle due to its own weight during the whole process of concrete pouring of the top cement pipe. Then, when the cement pipe is exposed to building reinforcement or the connecting anchor bolt of the template and other items just before the final setting but not before the final setting, this kind of foundation settlement will be blocked and will immediately cause cracks.

1. Before putting the cement pipe into use, check whether the cement pipe is intact. If there are cracks, repair them in time. If they cannot be repaired, replace them. Do not use damaged or inferior cement pipes, which will affect the safety of the project. 2. The workers of cement pipe laying must have professional experience, the relevant departments should do a good job in supervision, and each procedure should be well controlled, otherwise the unqualified foundation in the early stage will lead to more problems in the later construction, and the problem should not be buried underground, because maintenance will consume a lot of human and financial resources. 3. When laying pipelines, the established construction scheme shall be strictly followed, and do not make decisions or cut corners, otherwise the project quality will not be guaranteed. 4. After the cement pipe is laid, the special quality inspection department shall further review it to ensure the project quality.

When it comes to cement pipes, I believe you are no stranger. All kinds of cement pipes are widely used in daily life. However, although the cement pipe is very convenient to use, it also has a certain service life. 1. It is important to choose the type of cement. Only by selecting the type of cement that meets the requirements can the service life be increased. Therefore, the selection of raw material cement is also very critical. The selected cement type must meet the requirements in strength and fineness. Ordinary Portland cement is the best choice, and the setting time should not be too long. 2. Control the water cement ratio and cement consumption.
