Abstract

The invention provides a plastic electric cable well which is formed by assembling a bottom plate, U-shaped parts and insertion plates, wherein the height of the well body can be adjusted by increasing or reducing U-shaped parts and insertion plates, the bottom plate, the U-shaped parts and the insertion plates are prepared from an polyformaldehyde resin material, and the polyformaldehyde resin material comprises the following raw materials in parts by weight: 100-120 parts of polyformaldehyde resin, 30-50 parts of compound modified particles, 8-14 parts of ethylene bis stearamide, 0.1-1 part of a formaldehyde absorber and 0.2-0.6 part of an antioxidant. The electric cable well in the assembled structure is easy to process and manufacture, so that the production cost is lowered. The electric cable well is convenient to transport, carry and construct, so that the construction cost is lowered.

Description

technical field [0001] The invention relates to a plastic cable well, in particular to a cable well made of a polyoxymethylene-based toughening modified material. Background technique [0002] In the cable duct system, the cable shaft is a necessary structure, which has important functions such as connecting pipelines, inspecting and maintaining cables. It is generally divided into manhole well and hand hole well. The manhole well is relatively large, and people can go down into the well for construction operations. The hand hole well is generally relatively small, and only the hand can be reached in for operation. It is generally used on branch lines, and there are not many cables passing through the well. , easy threading. [0003] One of the traditional concrete pipeline manholes is built with red bricks. There are many masonry points and the control of impermeability is poor. The other is to use ordinary cement pressed bricks, each of which is basically the same size...
