Embodiment Construction

[0031] The inspection window of the present invention is mainly composed of a box body 2 and a movable cover plate 3 . The cross section of the box body 2 perpendicular to the axial direction of the drainage pipe 11 is rectangular, trapezoidal or stepped. It is arranged in the secondary lining 17 and is made of metal materials. It is fixed by welding, and can also be fixed by steel bars. Parts are connected with the steel bars in the secondary lining 17 to ensure that the box body 2 will not move or be damaged when the concrete of the secondary lining 17 is poured. Casing 2 also can adopt plastic material to make. The height of the box body 2 is consistent with the thickness of the secondary lining 17, and the movable cover plate 3 is flush with the surface of the secondary lining 17. In an environment with a relatively low temperature, thermal insulation material can be filled in the casing 2 to prevent the drainpipe 11 from freezing.

[0032] The movable cover plate 3 is c...

Abstract

The invention discloses an inspection window of a tunnel drainage system and a method for using the same, belonging to the technical field of tunnel drainage, comprising a box body which is arranged in a secondary lining on the surface of a drainage pipe; the top of the box body is connected with a movable cover plate , There are flanges around the bottom; the flanges are connected to the waterproof board, the waterproof board in the covered area of ​​the bottom of the box is provided with an inspection port, and the inspection port is covered and connected with an inspection cover. The height of the box body is consistent with the thickness of the secondary lining, and the movable cover plate is flush with the surface of the secondary lining. The invention is simple in type and convenient in installation. During tunnel operation, the tunnel drainage system can be inspected and maintained conveniently, ensuring the smooth flow of the tunnel drainage system without affecting the existing structure of the tunnel.

Description

technical field [0001] The invention relates to the technical field of tunnel waterproofing and drainage, in particular to an inspection window of a tunnel drainage system and a method for using the same. Background technique [0002] At present, in the tunnel structure with composite lining in the field of tunnel engineering, drainage pipes are usually laid between the primary support and the secondary lining, including circumferential drainage pipes, longitudinal drainage pipes, horizontal drainage pipes, and central gutters. Drain the water seepage behind the secondary lining and flashing to eliminate water pressure. However, during the operation of the tunnel, due to the sedimentation brought by the seepage, the drainage pipes are usually blocked, such as Chen Li’s published document "Research on the Problem of Drainage Pipe Blockage in Railway Tunnel Construction" ("Technology and Market", 2015, Volume 22, No. 4, Page 80, April 2015), pointing out that the tunnel drain...
