Prestressed steel cylinder concrete pipe structure and tool thereof

Abstract

The invention relates to the technical field of water pipes, in particular to a prestressed steel cylinder concrete pipe structure and a tool thereof. The prestressed steel cylinder concrete pipe structure comprises a steel cylinder and a stirring assembly, the steel cylinder is sleeved with a high-strength concrete core pipe, the high-strength concrete core pipe is wound with a prestressed steel wire, the prestressed steel wire is sleeved with a cement mortar protective layer, a limiting groove is formed in the inner ring surface of the high-strength concrete core pipe, a limiting column is inserted into the limiting groove, a guide-in plate is arranged on the surface of the limiting column, and a storage groove is formed in the surface of the limiting column. The prestressed steel cylinder concrete pipe structure and the tool thereof have the beneficial effects that the limiting groove is formed in the inner ring face of the high-strength concrete core pipe, the limiting column is arranged on the outer wall of the steel cylinder, and after the limiting column is inserted into the limiting groove, the sleeving position of the steel cylinder and the high-strength concrete core pipe is prevented from rotating, and the connection firmness of the steel cylinder and the high-strength concrete core pipe is improved.

Description

technical field [0001] The invention relates to the technical field of water pipelines, in particular to a prestressed steel cylinder concrete pipe structure and tooling thereof. Background technique [0002] Prestressed steel tube 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. It is a composite pipe composed of thin steel plate, high-strength steel wire and concrete. It fully and comprehensively exerts the tensile strength and easy sealing of steel and the compression and corrosion resistance of concrete. It has high sealing performance, high strength and high resistance. seepage characteristics. [0003] In the prior art, the connection strength between the steel cylinder of the prestressed steel cylinder concrete pipe and the high-strength concrete core pipe is low, and the phenomenon of mutual rotation between the tw...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the connection strength between the steel cylinder of the prestressed steel cylinder concrete pipe and the high-strength concrete core pipe is low, and the phenomenon of mutual rotation between the two pipe bodies is easy to occur, which affects the stable use of the prestressed steel cylinder concrete pipe
