Prestressed reinforced concrete pipe with built-in plastic sleeve socket

Abstract

The invention relates to a prestressed reinforced concrete pipe with a built-in plastic sleeve socket, which is composed of a socket, a socket, a concrete pipe core, a prestressed steel wire and a protective layer. At the end, the concrete core is coaxially embedded with a steel skeleton, and the two ends of the steel skeleton are respectively fixed on the socket and the socket, wherein a plastic sleeve is coaxially embedded in the concrete core, and the plastic sleeve The two ends are fixed on the socket and the socket. The present invention has simple overall structure, scientific and reasonable design, good impermeability, corrosion resistance, resistance to uneven settlement, low cost of raw materials and construction cost, simple construction process, and convenient maintenance. Prestressed reinforced concrete pipe with built-in plastic sleeve socket.

Description

technical field [0001] The invention relates to a concrete pipe, in particular to a prestressed reinforced concrete pipe with a built-in plastic sleeve socket. Background technique [0002] With the strengthening of infrastructure construction in our country, the demand for pipes is also increasing, especially for long-distance water delivery pipes. At present, in my country's long-distance water transmission pipelines, concrete pipes account for a large proportion, and the cores of concrete pipes are mostly cast in reinforced concrete. Among them, the impermeability of the pipe body is poor, and the socket socket made of concrete is weak in resisting the settlement of the foundation. After searching, it is found that a PCCP pipe is based on the existing concrete pipe, and its pipe core is The thin steel cylinder is coaxially embedded inside, and the two ends of the thin steel cylinder are welded to the steel socket and socket, which can meet the requirements of good impermea...

At present, in my country's long-distance water transmission pipelines, concrete pipes account for a large proportion, and the cores of concrete pipes are mostly cast in reinforced concrete. Among them, the impermeability of the pipe body is poor, and the socket socket made of concrete is weak in resisting the settlement of the foundation. After searching, it is found that a PCCP pipe is based on the existing concrete pipe, and its pipe core is The thin steel cylinder is coaxially embedded inside, and the two ends of the thin steel cylinder are welded to the steel socket and socket, which can meet the requirements of good impermeability, but today, the steel is increasing, which increases the The cost of raw materials also makes the manufacturing process very complicated, and the socket and socket of the pipeline are made of steel, which need to be treated with anticorrosion before the pipeline is buried, which greatly increases the cost of labor and raw materials. Long-term underground laying, the steel cylinder will also be corroded, resulting in high repair and maintenance costs, and the pipe body is heavy, and the transportation and construction costs are high
