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.

2. Establish temporary bench marks: temporary bench marks are often required for pipeline works, which should be set at a stable place that is not easy to be collided, and the spacing should not be more than 30 meters. The closure error of temporary benchmark shall meet the specified standards. 3. Trench excavation is mainly carried out by excavator, supplemented by manual bottom cleaning. Rainwater bucket connecting pipes and branch pipes are manually excavated. During excavation, pay attention to the change of soil quality, and support and enclosure the sections with signs of collapse. 4. Excavate by excavator until the elevation of the trench bottom is about 10cm. Do not excavate the reserved trench bottom soil, and then remove it manually to trim the trench bottom. Manually clean the tank, carefully check the soil at the bottom of the tank for disturbance, and if there is any disturbance, special treatment shall be carried out.

The bending resistance of thin-walled pipe piles is poor, especially the poor shear resistance and tensile resistance of the pile body, which has buried hidden dangers in the foundation of the building. Therefore, some national prestressed concrete pipe pile research meetings have clearly sent out information that the shear resistance and tensile resistance of pipe piles should be specified, and pipe piles should be carefully used in key projects, At the meeting, various experts demonstrated and looked forward to the pile type with square or polygonal external surface, hoping that China could move closer to the western developed countries and develop the foundation pile material with polygonal or variable diameter external surface. The prestressed concrete hollow square pile was developed for this purpose.

In the application of cement pipe, after the electric jack is used to jack in the lifting object, the supporting point of the lifting object shall be fixed with the support column immediately to avoid using the electric jack as the support column. The center of gravity of the lifting object shall be properly selected, and the power generating point of the electric jack shall be effectively selected. The bottom edge must be paved, and the standard of hard and soft pavement shall be fully considered. Whether to pad the tough wood, whether to place it stably, and avoid weight depression or skew. If the residual oil of the pump body is not enough, the pump must be filled with oil during operation before application.

7) The grout is repeatedly stirred and lifted. After sinking to the design depth, the grout is repeatedly stirred and lifted until it reaches the ground. 8) The pile driver is moved. After the construction of one pile, move the pile driver to the next pile position, and repeat the above steps for the construction of the next pile. Jiaxing cement pipeline, also known as cement pressure pipe and reinforced concrete pipe, can be used as sewer pipe in urban construction, sewage drainage, flood control and drainage, as well as water supply pipes and farm motor wells used in some special factories and mines. Generally, it is divided into: plain end reinforced concrete cement pipe, flexible rebated reinforced concrete cement pipe, socket reinforced concrete cement pipe, F-shaped steel socket cement pipe, plain end ring joint cement pipe, rebated cement pipe, etc.

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.
