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

Solution to surface crack of cement pipe. First of all, we should reasonably control the temperature raising speed inside the cement pipe. We can add appropriate mineral ash in the production of cement pipe to ease the release rate of water binder ratio; Secondly, by controlling the temperature of raw materials, we can select a condenser inside the cement pipe structure to cool the circulating water and release the specific energy of water glue. When cracks have already appeared, people usually paint cement mortar or low viscosity polymer for sealing to avoid water intrusion; If the crack is deep or wide, the working pressure grouting shall be used for technical repair. 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.

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.

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.

3. For the connection, as long as the flexible rubber ring is used, the street seal can work well. Long term operation. High quality, no leakage 4. The inner wall of the pipeline is flat and yellow, and the fluid friction is relatively small. If used on the ground, the service life will exceed 20 years. Cement pipes have been widely used in industrial production and urban planning and construction, and have played a key role, such as coating pipes used for drinking water, electric power engineering communication equipment, natural gas camp, etc., which must be laid underground. The quality assurance of infrastructure is the foundation of engineering construction in all big cities, so more stringent regulations must be made on the construction materials.
