High-quality prestressed steel cylinder concrete pipe and production process thereof

Abstract

The invention provides a high-quality prestressed steel cylinder concrete pipe and a production process thereof. The high-quality prestressed steel cylinder concrete pipe comprises a steel cylinder concrete pip, a bellmouth steel ring and a socket steel ring are correspondingly welded to the left end and the right end of the steel cylinder concrete pipe, and a protective mechanism is connected tothe outer part of the socket steel ring in a buckled mode. According to the high-quality prestressed steel cylinder concrete pipe, the protective mechanism is arranged on the socket steel ring weldedto the right end of the steel cylinder concrete pipe, when the steel cylinder concrete pipe needs to be stored after manufacturing, firstly a first elastic clamping hoop and a second elastic clampinghoop are installed at the socket at the right end of the socket steel ring, then the first elastic clamping hoop and the second elastic clamping hoop are fixed through two fastening mechanisms, the structure is simple, operation is convenient and fast, the working efficiency of the protective mechanism during installation is effectively improved, the protective mechanism is arranged, thus a secondannular groove formed in the socket steel ring can be effectively protected, thus the phenomenon of dust and other impurities adhering to the inner part of the second annular groove is avoided, and the sealing performance of the second annular groove after the installation of a sealing ring is improved.

Description

technical field [0001] The invention belongs to the technical field of prestressed steel cylinder concrete pipes, and more specifically relates to a high-quality prestressed steel cylinder concrete pipe and its production process. 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] For example, the application number: CN201710822956.3 Polymer-reinforced prestressed steel cylinder concrete pipeline forming process, which belongs to the technical ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a high-quality prestressed steel cylinder concrete pipe and its production process to solve the following deficiencies in the existing steel cylinder concrete pipe, such as: 1. The finished steel cylinder concrete pipe, During storage, it is usually stored in the open outside. In the environment of wind and rain, dust and impurities are easily attached to the annular groove on the steel ring of the socket. When the sealing ring is installed in the annular groove, the dust and impurities in the annular groove can easily cause a gap between the installed sealing ring and the socket steel ring, thereby reducing the tightness of the connection between the steel cylinder concrete pipes; 2 1. Although the prestressed steel wire is wound inside the existing steel cylinder concrete pipe, the bending resistance of the prestressed steel wire after winding is poor, thereby reducing the prestress of the steel cylinder concrete pipe; 3. Due to the external The lack of an effective limit structure makes it easy for the lifting equipment to slip during the lifting process due to the relatively smooth exterior of the steel tube concrete pipe when the lifting equipment is lifted by the rope
