Reusable drainage well

Abstract

The invention discloses a reusable drainage well. The reusable drainage well comprises a well body, butting pipes, a flange plate, a well neck, a well cover and a drainage tank; the well body is a cylindrical hollow shell of which the top end is open; at least two butting pipes are arranged in the well body and are perpendicular to the side surface of the well body; each drainage pipe is inserted into the corresponding butting pipe; the end surface, near the axis of the well body, of each drainage pipe is overlapped with the end surface, near the axis of the well body, of the corresponding butting pipe; the inside diameter of each butting pipe is much greater than the outside diameter of the corresponding drainage pipe; the overlapped end surfaces of each butting pipe and the corresponding drainage pipe are connected with each other through a flange plate; the well neck is arranged at the top of the well body; the well cover is arranged at the opening of the top end of the well neck; the well body is divided into two parts along the vertical direction, and the two parts are connected integrally through bolts; the well neck is divided into two parts along the vertical direction, and the two parts are connected integrally through bolts. The reusable drainage well can be mounted directly in an assembling form; the construction efficiency is greatly improved; the structure is solid; the well cover does not lose easily; the reusable drainage well can resist against the soaking of sewage, is low in comprehensive cost and can be reused.

Description

technical field [0001] The invention relates to the technical field of water supply and drainage equipment, in particular to a reusable drainage well. Background technique [0002] At present, in the sewer drainage wells used on residential buildings, factories and highways, the well wall and the well cover seat are all made of bricks and cement ash, and the well cover is buckled on the well cover seat. The shortcoming of this sewer drainage well is: [0003] (1) The well cover and the well wall are not integrated. The well wall and the well cover need to be processed separately. Each drainage well needs to be constructed and installed one by one. The construction period is long and the construction is inconvenient; [0004] (2) Because it is made of bricks, its firmness is poor, and the drainage well is easily damaged by vehicles; [0005] (3) The manhole cover is directly fastened on the manhole cover seat, and the manhole cover is easy to lose; [0006] (4) The brick we...

Problems solved by technology

[0003] (1) The well cover and the well wall are not integrated. The well wall and the well cover need to be processed separately. Each drainage well needs to be constructed and installed one by one. The construction period is long and the construction is inconvenient;

[0004] (2) Because it is made of bricks, its firmness is poor, and the drainage well is easily damaged by vehicles;

[0005] (3) The manhole cover is directly fastened on the manhole cover seat, and the manhole cover is easy to lose;

[0006] (4) The brick well wall is easily weathered and damaged by soaking in sewage for a long time, the service life is short, and the drainage well is easy to block;

[0007] (5) The comprehensive cost and cost of various materials, labor costs, various extraction fees and subsequent maintenance costs are high;

[0008] (6) After the drainage well is removed, construction waste will be produced, which cannot be recycled
