High-strength sediment inspection well

Abstract

The invention discloses a high-strength silt inspection well which comprises a well base and a mineshaft, wherein the well base, a mineshaft body and mutual connecting parts are connected with a reinforcement model by virtue of integral injection molding; the reinforcement model comprises a diaphram plate positioned at the joint of the well base and the mineshaft; the periphery of the separation plate is provided with a mounting ring positioned at the interior of a peripheral wall of the well base; the interior of the mounting ring is radially provided with a shim which is connected with a torsion spring; the upper and lower sides of the shim are connected with annular reinforced ribs; the peripheries of the annular reinforced ribs are wrapped with a one-piece nylon fabric. By utilizing the reinforcement model as an insert, a novel structure provided with the reinforcement model used as a keel and plastic used as a substrate is formed, so that the compression strength is enhanced; further, the nylon fabric is adopted as a bonding medium for connecting the reinforcement model with a plastic bracket, so that a cracking phenomenon caused by different self expansion and contraction rates of materials is avoided; by virtue of the diaphram plate structure, the shim can be opened due to weight under a condition that the weight of accumulated sludge is overhigh, so that the inspection well or a pipeline is prevented from being blocked.

Description

technical field [0001] The invention relates to an inspection well, in particular to a high-strength sedimentation inspection well. Background technique [0002] The inspection well is an auxiliary structure used for rain and sewage discharge pipes. It is a necessary facility for regular inspection and dredging of pipes to prevent pipe blockage. At present, various plastic drainage pipes have been widely used in municipal engineering and building districts, and their characteristics such as light weight, good impermeability, and convenient construction have been generally recognized. Due to the inconsistency of the deformation coefficient between the connections, the problem of leakage in the entire drainage pipe network is particularly prominent. In addition, there are inspection wells with plastic structures to solve the above problems. However, due to the concentration of stress in the inspection wells, it is required to have a large compressive capacity to prevent ruptu...

Problems solved by technology

At present, various plastic drainage pipes have been widely used in municipal engineering and building districts, and their characteristics such as light weight, good impermeability, and convenient construction have been generally recognized. Due to the inconsistency of the deformation coefficient between the connections, the problem of leakage in the entire drainage pipe network is particularly prominent

In addition, there are inspection wells with plastic structures to solve the above problems. However, due to the concentration of stress in the inspection wells, it is required to have a large compressive capacity to prevent rupture. However, ordinary inspection wells tend to be quickly blocked due to the limited volume and the sedimentation of sludge. How to solve the above technical problems has always been the research object of those skilled in the art.

There are no technical hints or solutions for pressure resistance and clogging prevention for this plastic manhole
