Embodiment Construction

[0032] 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.

[0033] The movable cover plate 3 is c...

Abstract

The invention discloses an inspection window of a tunnel drainage system and a using method thereof, and belongs to the technical field of tunnel water handling. The inspection window comprises a case body, and the case body is arranged in a secondary lining of the surface of a drainage pipe; a movable cover plate is connected with the top of the case body, and a flange is arranged at the periphery of the bottom of the case body; and the flange is connected with a waterproof board, an inspection opening is formed in the area, overlapped by the bottom of the case boy, of the waterproof board, and an inspection cover plate is connected on the inspection opening in an overlapping mode. The height of the case body is consistent with the thickness of the secondary lining, and the movable cover plate is aligned to the surface of the secondary lining. According to the inspection window of the tunnel drainage system, the type is simple, installation is convenient, the tunnel drainage pipe system can be inspected and maintained conveniently in a tunnel operation period, it is ensured that the tunnel drainage system is unlocked, and an existing structural style of a tunnel is not influenced.

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...
