How to distinguish between different cement pipes
Cement pipes, also known as cement pressure pipes and reinforced concrete pipes, can be used as sewage pipes in urban construction foundations, and can discharge sewage, flood and drainage, as well as water pipes and farm machinery wells used in some special factories and mines.
Cement pipe is divided into: flat mouth reinforced concrete cement pipe, flexible tongue and groove reinforced concrete cement pipe, socket socket reinforced concrete cement pipe, F-shaped steel socket cement pipe, flat mouth ring joint cement pipe, tongue and groove cement pipe and so on. In the meantime, the socket cement pipe uses a rubber ring to seal the water stop. It is a flexible connection. The penetration depth of the interface is 80-100mm, and the relative angle of the interface is 1.5 °. The cement pipe of the socket cement pipe has good seismic resistance. The base of the pipe is sandstone or concrete. , The device is fast. After the cement pipe is played, the cement pipe and the mold are placed in the open air for natural maintenance. Generally, after the cement pipe is played, it needs one day for open-air maintenance. The next two days can be opened, and after the mold is opened, it needs 4-6 days of natural maintenance. For maintenance, a special person sprays water on the cement pipe three times a day.The time is usually once in the morning, once at noon, and once in the afternoon.The purpose of water spraying is to maintain the humidity of the cement pipe so that the concrete can gradually set itself. Conditions and weather humidity increase and decrease the number of water sprays. The flat mouth pipe is an early form of interface for cement pipes, which is difficult to manufacture, has high production efficiency, and low manufacturing costs. The steel wire concrete tape is used as the interface seal for rigid connection. This connection method can transfer the load between the pipes. Increase sealing function. Generally, a sliding rubber ring is used for sealing and water stopping.
