Problems solved by technology

[0003] In water conservancy projects, the installed water pipelines and valves need to be buried for protection. At present, the valve inspection wells of water conservancy projects are usually built with bricks or concrete, which requires a lot of labor costs, high cost, low efficiency, and complex construction. The soil environment is prone to corrosion, water leakage and settlement, causing water pollution or geological disasters
And injection plastic well is owing to process characteristic, and well body is less, and all are assembled into small parts by injection molding (as the structural design disclosed in CN103132542A), it is inconvenient and underground water seepage also can occur when there is a problem and needs to be maintained.

Embodiment 1

[0028] The present invention constitutes the plastic formula of product:

[0029]

[0030]

[0031] The PE plastic material for manufacturing the valve inspection well is pulverized, and the particle size is two kinds of powdery plastics, 15 mesh and 50 mesh.

Embodiment 2

[0033] The present invention constitutes the plastic formula of product:

[0034]

[0035] The PE plastic material used to manufacture the valve inspection well is pulverized, and the particle size is two kinds of powdery plastics, 30 mesh and 35 mesh.

Embodiment 3

[0037] The present invention constitutes the plastic formula of product:

[0038]

[0039]

[0040] The PE plastic material used for manufacturing the valve inspection well is pulverized, and the particle size is two kinds of powdery plastics, 25 mesh and 40 mesh.

[0041] The manufacture method of well body 1 of the present invention has following steps:

[0042] 1. Mold design: Design axial and longitudinal grooves in the inner cavity of the well body mold, design the mold mouth with a structural mold that matches the well head, and design a straight pipe that matches the shape of the branch pipe under the well body mold mold;

[0043] 2. Accounting weight: Calculate the raw material weight M of the production valve inspection well according to the surface area S of the well body:

[0044] ①M=ρ×s×e

[0045] ②S=(πr 1 2 +2πr 1 h+πr 2 2 )*k

[0046] Among them: ρ - raw material density, about 0.93g / cm 3 ; e—well wall thickness; r 1 —well body radius; r 2 —well...

Abstract

The invention discloses an inspection well for an integrated anti-settling valve, which is a straight cylinder structure with a closed bottom, and integrally formed reinforcing ribs are provided on the outer wall of the straight cylinder; the straight cylinder is made of the following materials in parts by weight: polyethylene plastic 100, acrylonitrile -Butadiene-styrene plastic 2~3, 2-hydroxy-4-methoxybenzophenone 0.08~0.12, 1,1,3-tris(2-methyl-4-hydroxy-5-tert-butyl Phenyl)butane 0.2-0.5, titanate coupling agent 0.3-0.55, nano calcium carbonate 15-20, mold release agent 0.5-1.0, black powder 0.2-0.5, rodent-proof agent 0.5-1.5. The invention adopts rotational molding process for processing, no pressure forming, the material itself has no internal stress damage, high mechanical strength, no leakage, maintenance-free, long service life, good safety, large well space, convenient construction and short construction period Short, saving construction costs, it is a high-quality product for supporting water supply and fire protection projects.

Description

technical field [0001] The invention relates to the technical field of hydraulic engineering equipment, in particular to an inspection well for an integrated anti-subsidence valve. Background technique [0002] Premier Li Keqiang of the State Council pointed out in this year's government work report that the construction of 57 major water conservancy projects that have already started should be accelerated, and another 27 projects will be started this year. The investment scale of major water conservancy projects under construction exceeds 800 billion yuan. The construction of water conservancy projects is already one of the key areas of financial investment. Statistics show that in recent years, domestic investment in water conservancy projects has maintained a relatively high growth rate. Last year, the central investment in major water conservancy projects in my country reached nearly 40 billion yuan, and this year it will reach more than 70 billion yuan. Insiders of wat...
