A concrete pipe is a kind of prefabricated pipe made of cement and steel. It can be used as a sewage pipe in the city, as well as a water pipe used in some special factories. also known as cement pressure pipe, reinforced concrete pipe, it can be used as a city to build the base of the sewer, can discharge sewage, flood control drainage, as well as some special factories and mines used on the water pipes and farm machinery.
Generally divided into flat reinforced concrete cement pipe, flexible enterprise concrete reinforced concrete pipe, socket reinforced concrete cement pipe, F-shaped steel bearing cement pipe, flat mouth ring interface cement pipe, enterprise cement pipe;According to the different capacity of the pipe to withstand water pressure, it can be divided into low pressure pipe and pressure pipe. The working pressure of pressure pipe is generally 0.4, 0.6, 0.8, 1.0, 1.2 MPa, etc.
After the concrete pipe is finished, the cement pipe and the mold are placed in the open air for natural curing,After the cement pipe is finished, it takes one day for open-air maintenance after the cement pipe is finished. The mold can be opened the next day, and it takes 4 to 6 days after the mold is opened. For natural curing, a person is required to spray the cement pipe three times a day. The time is usually once in the morning, once in the afternoon, and once in the afternoon. The purpose of the water spray is to maintain the humidity of the concrete pipe so that the concrete can slowly solidify, and the number of water sprays can also be increase and decrease the number of water sprays depending on the weather conditions and the humidity of the weather.
