Wrapping formed inspection well prepared from plastic in environmental protection, and method of preparation

Abstract

The invention discloses an environmentally friendly plastic inspection well formed by winding and a preparation method thereof. The environmentally friendly plastic inspection well formed by winding is formed by 360-degree spiral winding and fusion bonding of strip-shaped or linear plastic or plastic composite materials around the central axis, and the strip-shaped or linear plastic or plastic composite materials are melt-bonded and connected to each other. There are spiral reinforcement ribs. Its manufacturing method is to make plastic profiles by the first extrusion equipment, matched molds and auxiliary equipment including cooling and traction; winding plastic profiles or plastic composite materials in the form of strips or wires on plastic pipes Winding is carried out on the machine, and at the same time, the molten material extruded by the second extrusion equipment is melted and bonded with the plastic material or plastic composite material being wound. In the present invention, the inner and outer walls of the plastic inspection well are flat, and the molten material in the well wall of this structure becomes the reinforcing rib, which enhances the ability of the well body to withstand external forces.

Description

technical field [0001] The invention relates to a plastic inspection well for water supply and drainage with spiral internal reinforcing ribs on the well wall, especially a disposable side made of tubular, strip or sheet plastic (which can be attached with reinforcing materials, such as metal). An environmentally friendly plastic inspection well formed by winding or segmented winding and a preparation method thereof. Background technique [0002] At present, inspection wells used as water supply and drainage pipes are generally made of cement and bricks or made of metal pipe fittings. Due to the harsh environment of sewage discharge, inspection wells made of metal materials are easy to oxidize safely and affect the service life, which increases the cost of the project and its own manufacturing costs; it is made of cement and bricks, which is prone to leakage and pollutes the environment. It has been reported that new materials are used to manufacture inspection wells, such ...

AI Technical Summary

Problems solved by technology

Due to the harsh environment of sewage discharge, inspection wells made of metal materials are easy to oxidize safely and affect the service life, which increases the cost of the project and its own manufacturing costs; it is made of cement and bricks, which is prone to leakage and pollutes the environment

It has been reported that new materials are used to manufacture inspection wells, such as plastics, but there are problems in process manufacturing and structure; poor sealing performance, prone to water leakage, insufficient strength, affecting engineering quality, difficult joints, and affecting pipelines Arrangement etc.
