Description

A New Type of Plastic Inspection Well

technical field

The utility model relates to the technical field of pipeline fittings, in particular to a novel plastic inspection well with strong pressure bearing capacity, water pressure resistance and floating prevention.

Background technique

Plastic inspection wells, commonly known as plastic inspection wells, are installed at the intersections, turnings, pipe diameter or slope changes, water drop places or at certain distances on straight pipe sections of plastic drainage pipes to facilitate regular inspection, cleaning and dredging of pipe drainage. Ancillary structures. Plastic drainage wells are easy to install, light in weight, easy to transport and install, reliable in performance, corrosion-resistant, aging-resistant, easy to connect with plastic pipes, and have good sealing performance. At the same time, they can effectively prevent sewage leakage, are safe and environmentally friendly, and the inner wall is smooth and not easy to block. , strong emission rate and other advantages have been gradually popularized and applied in our country.

However, due to its light weight, the plastic inspection well is easy to float up due to the buoyancy of water after being buried underground for a period of time, which will affect the transportation function of the pipeline. Infrastructure has an impact.

At the same time, the existing inspection well basically adopts a straight wellbore, and its structural strength in the circular direction and the vertical direction is relatively low. In the overall application of plastic inspection wells in buildings, because the size is much smaller than that of conventional brick drainage inspection wells, after the pressure drainage of the building enters the plastic inspection wells, the separation of water and air is not smooth, and the impact of water pressure on the erosion of inspection wells It is very large, and it is necessary to carry out certain anti-pressure treatment on the pressure drainage of the building to prevent the water pressure from directly rushing to the side wall of the plastic inspection well and causing damage to the plastic inspection well.

Utility model content

The purpose of the utility model is to solve the shortcomings of the existing plastic inspection wells that are not high in strength, unable to perform pressure-resistant treatment and easy to float, and provide a high-pressure safety inspection well with simple structure, anti-floating, high strength and effective water pressure resistance. Type plastic inspection well.

The utility model achieves the above object through the following technical solutions: a new type of plastic inspection well, including a well base, a well cover and a well shaft, the well base has at least two pipe ports, and the well shaft is connected to a pressure drainage outlet pipe; The outer wall of the wellbore is provided with a network-like structural reinforcement formed by crossing ring-shaped reinforcing ribs and oblique strip-shaped reinforcing ribs; the inner wall of the wellbore is provided with a compression plate, which is fixed to the inner wall of the wellbore, and The installation height of the plate is sufficient to make the drainage of the pressure drainage outlet pipe enter the wellbore and directly impact the pressure plate; the bottom of the well base is provided with a sedimentation chamber, and the lower end of the sedimentation chamber There is a weighted cavity in which a filler is placed.

Further, the pressure-resistant plate is a plastic plate or a metal plate with randomly arranged holes.

Further, the weighting chamber is connected to the bottom of the sludge chamber through threads.

Further, the network structure reinforcing ribs have the same thickness and height.

Further, the network structure reinforcing ribs have different thicknesses and heights.

Further, the filler is metal, stone or concrete.

The beneficial effects of the utility model are: the utility model is simple and compact in structure, and the production cost is low; it can effectively prevent the plastic inspection well from floating up, without affecting the overall characteristics of the inspection well, it protects the safety of the pipeline and ensures the normality of the basic settings. work; through the anti-compression plate set in the wellbore, the impact of pressure drainage on the plastic inspection well and the overall drainage system is solved; the network-like structural wall reinforcement formed by the intersection of ring-shaped reinforcement ribs and oblique strip-shaped reinforcement ribs can increase plastic inspection wells. The overall structural strength, that is, can play a role in strengthening the plastic inspection well in the horizontal and vertical directions, can effectively prevent the cracking of the plastic inspection well, and prolong the service life of the plastic inspection well.
