Abstract

The invention discloses a prestressed steel cylinder concrete pipe, which comprises a steel cylinder main body, a protective inner layer is poured inside the steel cylinder main body, and a prestressed high-strength steel wire is circumferentially wound around the outer surface of the steel cylinder main body. The outer edges of the prestressed high-strength steel wires are in contact with each other, the outer surface of the main body of the steel cylinder is poured with a protective outer layer, and the prestressed high-strength steel wires are located in the outer protective layer, and both ends of the outer surface of the main body of the steel cylinder are opened with a A connection groove, and a socket steel ring and a socket steel ring are respectively welded in the two connection grooves, and the outer surface of the socket steel ring is clamped with two sealing ring main bodies. A prestressed steel tube concrete pipe according to the present invention has stable structural performance, improves compressive strength, pipe body impermeability performance, joint sealing performance and pipeline anti-ground settlement and anti-seismic performance, and can not only be used as a water diversion pipeline, It can also be used as an urban pipe gallery, with various functions, and achieves effective results with the lowest economical cost.

Description

technical field [0001] The invention relates to the technical field of prestressed steel cylinder concrete pipes, in particular to a prestressed steel cylinder concrete pipe. Background technique [0002] Prestressed steel cylinder concrete pipe refers to a water pipe made by winding a hoop prestressed steel wire on a high-strength concrete core with a steel cylinder, and then spraying a dense cement mortar protective layer on it. In reality, this Pipes are widely used in main pipeline projects in the fields of urban water supply, drainage, industrial water transmission, irrigation water conservancy, and power plant supply water. In addition, they are also widely used in factory pipe networks, inverted siphons, pressure tunnel pipes, and deep-covered soil culvert pipes. [0003] During the use of the existing prestressed steel cylinder concrete pipe, the impact resistance and bearing capacity are low, easy to be damaged, and the cost is high. Therefore, we provide a prestre...
