Before the cement pipe is laid in the ground, professionals should check whether the cement pipe is in good condition and whether there are cracks. Small cracks can be repaired on the spot. If large cracks affect the construction safety, return to the factory and replace the qualified cement pipe. The foundation for pipeline laying must be strictly controlled. The cement pipe manufacturer shall be responsible for the construction and the quality department shall supervise the construction. The problems must be checked layer by layer. The problems shall not be buried underground, otherwise, the quality will directly affect the later construction, and further maintenance will consume more human and material resources. When laying the pipeline, the manufacturer's construction team shall strictly follow the construction scheme, and shall not change the construction scheme or cut corners without authorization, otherwise the hidden dangers of engineering quality left after laying will be seriously affected.

Principle of pipeline well crossing method: when the cement pipeline meets the crossing of existing pipelines or rainwater and sewage pipes during burial, the pipeline well crossing method is adopted, which can reduce the buried depth of the pipeline and is not easy to block. An inspection well shall be set at the intersection of pipelines to let another pipeline pass through the well. The key is to ensure that the water flowing area in the well (the area of the shadow part in the figure) is greater than or equal to the sectional area of the pipeline to be passed through. The size of the water flowing area in the well can be controlled by the size of the pipe passing inspection well. The principle of pipe passing is small pipe passing through large pipe, and the current pipeline passing through the planned pipeline.

In the existing market, cast-in-place pipe sinking piles, precast concrete piles, bored cast-in-place piles and prestressed concrete pipe piles are widely used. Among the above pile types, prestressed concrete pipe piles are widely used due to the advantages of factory prefabrication, high concrete strength, convenient construction, and fast cycle, while cast-in-place pipe sinking piles are difficult to ensure their quality due to the need for on-site production, Due to serious environmental pollution, it is not suitable for geological conditions with thick soft soil layer, which is prone to necking, and the construction period is very long, so it has gradually been eliminated by the market. For example, the Guangdong Provincial Construction Commission has clearly stipulated that the use of immersed cast-in-place piles is not allowed, and the Zhejiang Provincial Department of Construction has also restricted the use of immersed cast-in-place piles.

Before application, be sure to check whether each part is normal, and ensure the safety factor of each rubber hose connection. With the continuous and sustainable development trend of cement pipes and the increasing number of applications, problems such as pipeline leakage of cement pipes due to design, production and manufacturing or lack of maintenance have arisen. This has seriously affected the product quality of cement pipes and threatened everyone's personal safety. Therefore, we must strictly inspect the cement pipes in the whole process of application, so that we can see what problems are likely to occur in the whole process of application of cement pipes.

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.
