Problems solved by technology

[0004] It is inconvenient to install and disassemble the existing concrete pipes, and the large diameter requires operators to enter to complete the repair and installation operations, which is very inconvenient; the cutting efficiency of the existing cutting equipment for concrete pipe manufacturing is not high, and continuous cutting cannot be achieved cutting, which greatly increases the workload of the operator; the existing cutting equipment for concrete pipe manufacturing cannot meet the cutting of different heights, the scope of application is narrow, and the lack of a fixing mechanism causes the PP pipe to easily shift during cutting, reducing the cutting efficiency. precision

Abstract

The invention discloses a socket-and-spigot PP inner wall reinforced concrete pipe. The socket-and-spigot PP inner wall reinforced concrete pipe comprises a PP layer, wherein the outer side of the PP layer is wrapped with a concrete layer; a steel ring is fixed at one end of the concrete layer; the section of the steel ring is in the shape of an equilateral trapezoid. A preparation method of the socket-and-spigot PP inner wall reinforced concrete pipe comprises the following steps: step 1, preparing a PP pipe; step 2, preparing concrete; and step 3, pouring the concrete obtained in the step 2 outside the PP pipe through a reinforcing steel bar mold to obtain a tongue-and-groove PP inner wall reinforced concrete pipe. According to the socket-and-spigot PP inner wall reinforced concrete pipe, the steel ring is arranged at one end of the pipe, so that the pipe is more convenient to disassemble and assemble, and a large amount of manufacturing cost is saved for the PP inner wall pipe. Through the arrangement of a fixing mechanism, the PP pipe can be well fixed, so that the PP pipe cannot deviate during cutting; a moving rod can move randomly in the vertical direction, so that the socket-and-spigot PP inner wall reinforced concrete pipe can adapt to cutting at different heights and is wider in application range.

Description

technical field [0001] The invention relates to the technical field of concrete pipe manufacture, in particular to a socket type PP inner-wall reinforced concrete pipe. Background technique [0002] PP pipe is a non-toxic, hygienic, high-temperature-resistant and recyclable pipe type. It is mainly used in the indoor cold and hot water supply system of buildings, and is also widely used in heating systems. [0003] The characteristics of PP pipe are no rust, wear resistance, no scaling, reduced vibration and noise, and anti-freeze cracking (the PP pipe will freeze and crack at a low temperature exceeding -20°C, and the high-temperature working environment will decompose as long as it exceeds 70°C. temperature range from -20°C to 70°C), anti-condensation, less heat loss, simple installation and long service life. There are three kinds of connection methods: welding method, edge welding method, and different material connection. [0004] It is inconvenient to install and disa...
