Spigot and socket type RPC thin-wall oval-cross-section pipe and construction method thereof

Abstract

The invention provides a spigot and socket type RPC thin-wall oval-cross-section pipe and a construction method thereof. The spigot and socket type RPC thin-wall oval-cross-section pipe comprises a pipe body, a socket section and a spigot section, wherein the socket section and the spigot section are arranged at the two ends of the pipe body respectively. The cross section of the pipe body is shaped like an oval ring, and the oval ring comprises a top arc section, a bottom arc section and two side arc sections located between the top arc section and the bottom arc section. According to the spigot and socket type RPC thin-wall oval-cross-section pipe and the construction method thereof, the RPC material is introduced into drain pipe design; meanwhile, on the premise that the inner width and inner height of the oval-cross-section pipe guarantee that the flow area of the oval-cross-section pipe is equal to that of a round pipe with the diameter of 1200 mm, optimization is constantly carried out through stability and mechanics calculation, and finally the inner width and inner height of the oval-cross-section pipe are determined, so that compared with oval-cross-section pipe of other sizes, the oval-cross-section pipe is better in stability and shock resistance and higher in bearing capacity.

Description

technical field [0001] The invention relates to the design field of drainage pipes, in particular to a socket type RPC thin-walled elliptical cross-section pipe and a manufacturing method thereof. Background technique [0002] There is still a lot of room for development in the construction of drainage pipes in my country. The "2014 National Urban and Rural Construction Bulletin" shows that at the end of 2014, the length of drainage pipes per capita in my country was 1.075 meters, while the length of drainage pipes per capita in Germany reached 5.44 meters in the same period. At the same time, some large The drainage pipes in the old urban areas were built earlier, and the drainage rate is relatively slow, and some of them are close to the service life, which makes the drainage capacity of the drainage pipes very limited. In view of the above problems, once heavy rainfall occurs in major cities, the drainage system will often be overburdened and flooded, which will have a gre...
