Embodiment Construction

[0027] The present invention will be further described below in conjunction with accompanying drawing:

[0028] Such as Figure 5 As shown in , it is a schematic structural diagram of a tunnel composite lining structure with a maintainable drainage channel.

[0029] The tunnel composite lining structure with a maintainable drainage channel of the present invention comprises an arch wall lining 1, the lower end of the arch wall lining 1 is connected with an inverted arch lining 14, a construction joint 11 is arranged at the connection part, and an inverted arch lining 14 is provided with Several invert lining openings 141.

[0030] The upper supporting arch structure 2 is erected on the inverted arch lining 14, and the drainage channel 24 is formed between the inverted arch lining 14 and the upper supporting arch structure 2; the initial support 13 of the wall corner is enlarged to ensure the stability of the upper supporting arch structure; The structure 2 is filled with an ...

Abstract

The invention discloses a tunnel combined-type lining structure with a maintainable drainage passage. The structure includes an arch wall lining, the lower end of the arch wall lining is connected with a an inverted arch lining, an upper bearing arch structure is erected on the inverted arch lining, and the drainage passage is positioned between the inverted arch lining and the upper bearing archstructure; the upper bearing arch structure is filled with an upper arch padding layer, and an inspection well is formed in the upper bearing arch structure and the padding layer. The structure can solve the problem that the tunnel design in the prior art cannot achieve the capability of draining and guiding a large amount of underground water in a short time; the tunnel combined-type lining structure is reasonable in structure and high in reliability.

Description

technical field [0001] The invention relates to a tunnel lining structure, in particular to a tunnel composite lining structure with a maintainable drainage channel. Background technique [0002] China is the country with the widest distribution of karst, and the karst area accounts for about one-third of the country's land area, covering many provinces, municipalities, and autonomous regions. The developed karst geology not only brings great difficulty to the tunnel construction, but also seriously threatens the operation safety of the tunnel. With the completion and operation of more and more karst tunnels, the lining cracks, water leakage, floor heaving and other diseases of karst tunnels occur from time to time during the operation period. [0003] Disease accidents in karst tunnels during operation are not uncommon. For tunnels in karst formations or large buried deep water-rich formations, after a large amount of surface water is replenished, due to factors such as in...
