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.

Embodiment 1

[0035] An environmentally friendly plastic inspection well formed by winding, the strip-shaped or linear plastic or plastic composite material 1 is spirally wound and melt-bonded at 360 degrees around the central axis, and the strip-shaped or linear plastic or plastic composite materials are mutually fused There are spiral reinforcement ribs at the glued joints. The strip-shaped or linear plastic or plastic composite material is helically wound and melt-bonded at 360 degrees around the central axis to form the inspection well body 32 . The strip-shaped or linear plastic or plastic composite material is spirally wound 360 degrees around the central axis to form the inspection well parts, and each part is snap-fitted to form the inspection well, or a plastic sealing sleeve or rubber ring 33 connect. The cross-section of the strip-shaped or linear plastic or plastic composite material is circular or rectangular. The diameter of the strip-shaped or wire-shaped plastic or plastic...

Embodiment 2

[0037] Check whether the upper well body 32 is equal diameter or unequal diameter or axis offset. The unequal-diameter axis-offset well body is mainly used in inspection wells of large-diameter main well bodies (above 1200mm), which is beneficial to the setting of climbing devices and the up and down of maintenance workers. The partial section of the 360-degree spiral-shaped plastic inspection well wall is as follows image 3 shown.

[0038] In the plastic inspection well with the above structure, the reinforcing rib and its basic profile structure can adopt different structures according to the application field or purpose. For example, from the shape of the well wall section 34, a rectangular sheet can be used, or a hollow rectangular bar, pipe, bar, etc. can be used, plastic can be used completely, or composite materials such as plastic and steel or aluminum or fiberglass can be used. Said plastics include polyvinyl chloride, polyethylene, polypropylene or other modified ...

Embodiment 3

[0043] A method for manufacturing an environmentally friendly plastic inspection well body by winding. The environmentally friendly plastic inspection well body is manufactured according to the following steps: a. The granular plastic is passed from the first extrusion molding equipment and the matching mold and includes cooling, Auxiliary equipment including traction is made into strip-shaped or linear plastic profiles with a diameter of 50 mm; or granular plastics are melted by the first extrusion equipment and steel or aluminum or glass is added to the mold during the molding process The fiber is made into a strip-shaped or linear plastic composite material with a diameter of 50 mm; the temperature of the feed section of the extrusion equipment is 160 ° C, and the temperature of the exit section of the extrusion equipment is 180 ° C; b. The plastic profile or plastic composite material is wound on the plastic pipe winding molding machine, and the molten material extruded by ...

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 ...
