Cement pipe drainage pipe body has many characteristics. Its heat resistance, flame retardancy and resilience are outstanding features. It is not metal but pipe. No magnetism. Therefore, when placed in the cement tank, no vortex will occur. Cement pipes can be used in many fields, such as rainwater drainage, sewage drainage, industrial wastewater drainage and community drainage. As well as the buried pipelines of highways, or for protecting cables, optical cables, etc. Then the cement pipeline has the following characteristics: 1. Generally speaking, it has rigidity, flexibility and excellent mechanical properties. And it has strong compressive properties. 2. The chemical property is stable, generally corrosion resistant, but non-toxic, and it is an excellent environmental protection pipe.

Before the cement pipe is laid down, the elevation of the pipe top shall be controlled with a level gauge. The pipes shall be arranged from low to high. The pipes shall be placed in place and then corrected manually with excavator. The socket and spigot shall face the upstream direction, and the inner wall of the socket and spigot shall be coated with washing water, so that the rubber ring can slide in smoothly when inserting pipes and facilitate installation. In addition, the cement pipes passing the installation inspection shall be backfilled immediately, and the pipes with larger specifications shall be backfilled to at least one time the pipe diameter above the pipe top to ensure that the cement pipes can avoid directly loading the ground pressure. After backfilling, the ground shall be cleaned. In this way, the laying of a cement pipeline can be completed, and a complete underground pipeline system can be officially put into use, making its due contribution to the environmental protection construction of the city.

Maintenance means no steam curing tank. After the cement pipe is made on the cement pipe making machine, it is not necessary to open the grinding tool. Put the cement pipe mold and cement pipe outdoors for regular maintenance. Generally, after the cement pipe is made, it takes one day to carry out outdoor maintenance. The grinding tool can be opened the next day. After the mold is made, it also needs to carry out 4-6 days of regular maintenance, and full-time personnel should spray water on the cement pipe three times a day, The time of sprinkling is usually once in the morning, once in the afternoon and once at noon. The purpose of sprinkling is to maintain the environmental humidity of the cement pipe so that the concrete can gradually coagulate itself. The frequency of sprinkling can also be increased and reduced according to the environmental humidity of seasonal changes in weather conditions. But of course, there are more cement pipe molds required for maintenance.

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.
