2、 Why the price of reinforced concrete cement pipe fluctuates. In economics, an important factor affecting the price is people's demand for this product. This is an important factor. When the demand is greater than the supply, the supply falls short of demand, and the price will naturally rise; But when the demand is less than the supply, when the supply exceeds the demand, the price will naturally decline, but the rise and decline will not be too high or too low. The higher the value, the higher the price. The lower the value, the lower the price. This supply is affected by many factors.

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.

5. The pipe clamp to be used shall not be fixed with hook nails to prevent damage to the water pipe and reduce its service life. The distance between cold water pipe clamps is 50 ± in general, and the distance between hot water pipe clamps is 35 ±. If the pipe clamps are not in place, the water pipes will shake and produce noise. 6. The water pipe shall be horizontally flat and vertically straight (on the premise that the grooving is horizontally flat and vertically straight) to avoid hard pulling or twisting the water pipe, which will cause the outlet not parallel to the wall, affecting the appearance and installation of the mixing tap. 7. When the waterway is reconstructed, the reserved cold and hot water for future installation of electric water heaters, water taps, etc. shall be supplied with water.

Compared with other pile types, especially prestressed concrete pipe piles, hollow square piles have the following outstanding advantages: ① large surface area and square or polygonal angle, the angle of repose between the pile and the soil in the soil layer is much larger than the circular surface, which means that hollow square piles can obtain greater bearing capacity than pipe piles under the same geological conditions, saving a lot of foundation funds for the project; ② By comparison, the bearing capacity of 350 hollow square piles is equivalent to that of 500 outer diameter thick wall pipe piles, and the cost per KN bearing capacity is lower than that of prestressed concrete pipe piles, which means that designers can select square piles under the same design bearing capacity, while the market price of 350 hollow square piles is less than that of 500 outer diameter thick wall pipe piles, which can save a lot of material costs;

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.
