Problems solved by technology

[0004] Traditional inspection wells are brick inspection wells. Due to geological subsidence problems during use, there are many problems in the construction process. Previously, the production of plastic inspection wells was produced by rotational molding process, the product quality was unstable, and the production efficiency was low.

Abstract

The invention discloses a preparation method of an HDPE injection molding inspection well. The method comprises the following steps of: raw material mixing, plasticizing injection, die molding, cooling, finishing and warehousing. The method adopts an HDPE material to produce the plastic inspection well through injection molding. As the product is molded through injection molding and pressure maintaining, it has stable quality, and has all performances exceeding those of traditional rotational molding products. The invention makes use of the recycled HDPE raw material, and adds reinforced materials for filling, thus being in favor of waste utilization. The prepared inspection well has the advantages of: low cost, light weight, great strength, convenient construction, and excellent toughness.

Description

technical field [0001] The invention mainly relates to a preparation method of a plastic product, in particular to a preparation method of an HDPE injection molding inspection well. Background technique [0002] The inspection well is used in the building area (residential area, public building area, factory area, etc.) to buried plastic drainage pipes with an outer diameter of no more than 800mm and a buried depth of no more than 6m. Or the place where the slope changes, the place where the water falls, etc., in order to facilitate regular inspection, cleaning and dredging or downhole operation, the well-shaped structure is made of plastic injection molding or bricks for inspection; [0003] Plastic integrated injection molding inspection well means that the main well seat part of the inspection well is formed by one-time injection molding. According to the number and angle of connection, there are initial well bases, straight well bases, 45-degree elbow well bases, th...
