When it comes to cement pipes, I believe you are no stranger. All kinds of cement pipes are widely used in daily life. However, although the cement pipe is very convenient to use, it also has a certain service life. 1. It is important to choose the type of cement. Only by selecting the type of cement that meets the requirements can the service life be increased. Therefore, the selection of raw material cement is also very critical. The selected cement type must meet the requirements in strength and fineness. Ordinary Portland cement is the best choice, and the setting time should not be too long. 2. Control the water cement ratio and cement consumption.

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.

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

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.

Temperature: for the solidified mortar layer or concrete component, if the cement pipe factory is often in high temperature and extreme heat conditions, there will be strength loss. This is because the calcium hydroxide in the cement stone will be separated under high temperature conditions. In addition, some aggregates will separate or expand in volume under high temperature conditions. Cement raw materials: when selecting cement, cement varieties with high strength, good durability, appropriate price and reliable quality should be selected. The cement varieties with special properties shall be selected according to the service conditions of cement pipes; It is an important condition to ensure the durability of cement pipes to select better sand and stone aggregates, and sand and stone aggregates with good quality and qualified technical conditions.

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.
