Machining method of all-steel-jacket glass fiber reinforced plastic mortar pipe

Abstract

The invention provides a machining method of an all-steel-jacket glass fiber reinforced plastic mortar pipe, belongs to the technical field of machinery and solves the problem about low stability of the prior art. The machining method of the glass fiber reinforced plastic pipeline comprises the following steps: step A, preparing materials, namely preparing a pipe body I which is made of a glass fiber reinforced plastic material and a metal body II which is made of a metal material, wherein the outer diameter of the pipe body I is matched with the inner diameter of the pipe body II; step B, embedding, namely embedding the pipe body I into the pipe body II to realize close fit of the pipe body I and the pipe body II; step C, trepanning, namely forming a through hole A and a through hole B in the pipe body I; step D, positioning, namely inserting a metal pin into the hole A; and step E, fixing, namely injecting glue via the hole B, wherein the glue uniformly enters a clearance between the pipe body I and the pipe body II, and the pipe body I and the pipe body II are stably fixedly connected with each other after the glue is solidified.

Description

technical field [0001] The invention relates to a processing method for a glass fiber reinforced plastic sand-filled pipe jacking used in a water supply and drainage system, in particular to a processing method for a full-steel jacket glass fiber reinforced plastic sand-filled pipe jacking. Background technique [0002] At present, there are generally two ways in the laying of municipal pipelines. One is large excavation. This method is more convenient for construction, but it is limited by environmental factors. The other is non-excavation excavation. This method is less affected by environmental factors and is suitable for small construction sites and complex surrounding terrain. [0003] Cast iron pipe and FRP sand pipe jacking are two commonly used pipe jacking materials. Due to the outstanding mechanical properties of the material itself, cast iron pipes have the characteristics of high strength and sufficient toughness, but the disadvantages are high cost, poor sealin...

AI Technical Summary

Problems solved by technology

However, the existing FRP sand-filled pipe jacking has a single structure, and the strength of the FRP pipe body is relatively low compared to metal materials, and the FRP sand-filled pipe jacking is brittle and explosive.
