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.

Before the cement pipe is laid down, the elevation of the pipe top shall be controlled with a level gauge. The pipes shall be arranged from low to high. The pipes shall be placed in place and then corrected manually with excavator. The socket and spigot shall face the upstream direction, and the inner wall of the socket and spigot shall be coated with washing water, so that the rubber ring can slide in smoothly when inserting pipes and facilitate installation. In addition, the cement pipes passing the installation inspection shall be backfilled immediately, and the pipes with larger specifications shall be backfilled to at least one time the pipe diameter above the pipe top to ensure that the cement pipes can avoid directly loading the ground pressure. After backfilling, the ground shall be cleaned. In this way, the laying of a cement pipeline can be completed, and a complete underground pipeline system can be officially put into use, making its due contribution to the environmental protection construction of the city.

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.

Principle of intercepting tank method: in the sewage drainage system, the intercepting tank is used to block the substances that are easy to deposit in the sewage, so as to prevent pipe blockage caused by the reduction of pipe slope and flow rate, so as to reduce the value of smaller planned flow rate and smaller planned slope of the cement pipe as appropriate, so as to reduce the buried depth of the cement pipe. During detailed planning, ordinary septic tank can be used as interception tank. Since the intercepting tank mainly blocks the easy sediment in the sewage and does not need anaerobic fermentation to purify the sewage, the volume of the sewage part can be taken as 1/3 of the normal septic tank, while the volume of the whole intercepting tank is about 1/2 of the normal septic tank.
