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.

Precautions for installation and connection of cement pipe 1. The newly welded joint can be corrected within the specified cooling time, and a small amount of rotation is allowed. However, after the cooling time, forced correction is strictly prohibited. Note: The connected pipes and pipe fittings shall not be inclined. They shall be basically horizontal and vertical to avoid incorrect angle when installing the faucet. 2. It is forbidden to let the newly processed joint bear external force within the specified cooling time. 3. When PP-R pipe fittings with metal threads are used, the white raw material tape must be firmly sealed to avoid water leakage from the threads. 4. When overtightening PP-R pipe fittings with metal threads, the pipe fittings may be cracked, resulting in water leakage. Pay attention to the appropriate force.

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.

With the improvement of people's requirements for living environment, various construction measures have also raised the requirements accordingly. In the construction of drainage and sewage pipelines for urban construction, the requirements for the installation of cement pipelines have also been raised accordingly. This not only makes strict requirements on the quality and material of cement pipes, but also regulates the construction. Corresponding construction management specifications have also been formulated for the installation of cement pipelines. First of all, during installation, it is necessary to measure and set out first, and then dig trenches and earth according to the specifications of cement pipes. When laying the pipeline, the pipeline foundation construction shall be carried out first, and then the cement pipeline shall be cleaned inside the pipe, and then the concrete pouring inspection well and the anchor pouring shall be carried out. After these works are completed, the trench shall be backfilled as required.

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.

The newly developed hollow square pile has completely overcome this disadvantage by combining centrifugal and prestressed technology with internal hollow. In the market, prestressed concrete pipe piles are used more frequently in industrial and civil buildings. They overcome the shortcomings of the previous pile types and have their own characteristics, but the disadvantages are also obvious: the appearance is smooth and round, especially when used as friction piles, the friction force with soil is small, and many projects have to use pipe piles with large outer diameter or simply use solid square piles, Increased project cost; The bending resistance of thin-walled pipe piles is poor, especially the shear resistance and tensile resistance of the pile body, which has buried hidden dangers in the foundation of the building
