1、 Factors affecting the price fluctuation of reinforced concrete cement pipes. 1. The quality of materials used for cement pipes will affect the price of cement pipes: generally speaking, the price of cement pipes will be slightly higher than the market average price if the quality of raw materials used for cement pipes is high, while the price of cement pipes with ordinary quality will be slightly lower. 2. The manufacturing process of cement pipes will also affect the price of cement pipes: generally, different types of cement pipes adopt different manufacturing processes, some are complex and tedious, some are simple and take less time, so the prices of different cement pipes will be different.

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.

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 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
