Plastic, concrete and fiber composite pipe with reinforcing rib

Abstract

The invention provides a plastic, concrete and fiber composite pipe with a reinforcing rib. The pipe comprises a plastic plate strip, wherein the edges of the plastic plate strip are lapped or welded to form a pipe wall; a clamping groove is formed on the plastic plate strip; the reinforcing rib is embedded into the clamping groove; a concrete cavity is formed between the outer side wall of the reinforcing rib and the inner side wall of the clamping groove; notches of the clamping groove are sealed by a sealing layer; a fiber layer made of a fiber mesh or a fiber strip is wound on the outer wall of the weld of the plastic plate strip; an anti-cracking layer is formed on the outer wall of the fiber layer through glue coating; and concrete is filled in the concrete cavity. The pipe has the advantages that: 1, the concrete is poured into a hollow ridge, and a reinforcing rib steel strip is not required to be wound any more, so that raw materials are saved, and the production cost of the pipe is greatly reduced; 2, the outer wall of the weld is coated with the fiber layer, so that the pressure resistance of the weld of the plastic plate strip is greatly improved; 3, after the steel strip is arranged, the pressure resistance of the pipe is greatly improved; and 4, by rolling a hole on the steel strip, the concrete, the steel strip and the plastic plate strip can be well combined into a body, an expansion and contraction coefficient among different materials is reduced, the pipe is effectively prevented from being cracked or deformed, and the reinforcing rib is prevented from being rusted.

Description

technical field [0001] The invention relates to the technical field of pipe material production, in particular to a plastic, concrete and fiber composite pipe with reinforcing ribs. Background technique [0002] Replacing steel with plastic and developing pipeline transportation are two major development trends. Among them, plastic pipes have been widely used due to their high performance, high strength, light weight, wear resistance, corrosion resistance, low price and large diameter. Pipes have poor rigidity and temperature resistance and cannot be used in fields such as oil transportation and high-pressure water transportation; while metal pipes are characterized by good mechanical strength and no deformation, but due to their poor corrosion resistance and short life, water leakage often occurs. Rust pollutes water quality and other issues. At present, steel-plastic composite pipes are mostly used in the market. The structure of this type of pipe is: while winding with a ...

[0002] Replacing steel with plastic and developing pipeline transportation are two major development trends. Among them, plastic pipes have been widely used due to their high performance, high strength, light weight, wear resistance, corrosion resistance, low price and large diameter. Pipes have poor rigidity and temperature resistance and cannot be used in fields such as oil transportation and high-pressure water transportation; while metal pipes are characterized by good mechanical strength and no deformation, but due to their poor corrosion resistance and short life, water leakage often occurs. Rust pollutes water quality and other issues. At present, steel-plastic composite pipes are mostly used in the market. The structure of this type of pipe is: while winding with a plastic strip with a hollow wall, it is synchronized into the hollow wall of the plastic strip. Insert a reinforcing rib made of steel belt, which is formed in the same shape as the inner wall of the hollow wall, and finally the outer wall of the tube is formed by rubber-covering and rolling. The disadvantage of this type of structure is that because the steel belt is wound locally, only The local resistance of the pipe is strengthened, and the welded part of the strip is easy to break; and the expansion coefficients of the steel strip and the plastic are different, so they cannot be combined into one
