The theoretical calculated shear resistance of square pile is 2-3 times of that of the same pipe pile. According to the actual test of Japan's Ministry of Construction, it is 4.5 times of that of the pipe pile. This shows that the seismic performance of hollow square pile is very superior, and it is worth popularizing in earthquake prone areas, high-rise buildings, and building foundations with large areas of basements; The hollow square pile inherits and develops the low construction damage rate of the original concrete square pile. The high-strength concrete with a square head has better impact resistance than the pipe pile, and a much smaller damage rate of the pile head; The square has a larger welding perimeter than the round, fully ensuring the effective welding strength between each section of the pile, greatly reducing the joint desoldering or displacement of the square pile during construction, and making the pile quality better

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.

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 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. 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.
