Prestressed reinforced concrete pipe built-in with plastic sleeve faucet

Abstract

The invention relates to an bell-spigot prestressed concrete reinforced pipe with an internal plastic sleeve, which is composed of a bell mouth, a spigot mouth, a concrete pipe core, an prestressed steel wire and a protective layer, the bell mouth and the spigot mouth are respectively coaxially mounted at two ends of the concrete pipe core fixedly, a reinforcement cage is embedded coaxially in the concrete pipe core, two ends of the reinforcement cage are respectively mounted on the bell mouth and the spigot mouth fixedly, wherein a plastic sleeve is embedded coaxially in the concrete pipe, and two ends of the plastic sleeve are fixedly mounted on the bell mouth and the spigot mouth. The bell-spigot prestressed concrete reinforced pipe with the internal plastic sleeve is simple in integral structure, scientific and reasonable in design, and relatively fine in impermeability and noncorrosibility, resists uneven settleability, and further is low in raw materials cost and construction cost, simple in construction technique and convenient in maintenance and repair, and relatively high in creativity.

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
