Problems solved by technology

[0003] The tunnels built in the past are relatively outdated in terms of drainage concept, drainage materials, drainage technology and equipment, so the drainage system often has the following problems: fine particles in the surrounding rock can easily enter the drainage system, because there is no effective removal Therefore, the drainage system is often blocked; i

Embodiment Construction

[0014] Such as Figure 1-Figure 3 As shown, the maintainable tunnel drainage system provided by the present invention includes two longitudinal drainage ditches 1, a plurality of horizontal and vertical drainage blind pipes 2, 9, a plurality of annular blind pipes 3, a plurality of inspection wells 4 and two side Ditch 5; two longitudinal drainage ditches 1 are respectively arranged inside the molded concrete layer 6 on both sides of the tunnel bottom along the longitudinal direction of the tunnel, and are connected to the water collection pump station; multiple horizontal and vertical drainage blind pipes 2 and 9 are criss-crossed It is connected between two longitudinal drainage ditches 1, and a plurality of water collection holes are formed on the upper peripheral surface; a plurality of circumferential blind pipes 3 are arranged on the molded concrete layer 6 of the vault along the circumferential direction of the tunnel at intervals. Among them, a plurality of water colle...

Abstract

The invention discloses a maintainable tunnel drainage system, which comprises two longitudinal drainage ditches, a plurality of transverse and longitudinal drainage blind-ended tubes, a plurality of circumferential blind-ended tubes, a plurality of inspection shafts and two side ditches. The maintainable tunnel drainage system provided by the invention collects leakage water at the top and bottom of an arch of a tunnel, road surface water and flushing water by using the plurality of transverse and longitudinal drainage blind-ended tubes below a road surface, the plurality of circumferential blind-ended tubes behind a lining and the side ditches on two sides of the road surface respectively, gathers the water into the longitudinal drainage ditches on two sides of a roadbed and then drainsthe water out of the tunnel together, so that the stereoscopic tunnel drainage system is formed. In addition, when the longitudinal drainage ditches are blocked, the inspection shafts flush the longitudinal drainage ditches with high-pressure water, so that the whole drainage system can be maintained.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction, in particular to a maintainable tunnel drainage system. Background technique [0002] The drainage system of a tunnel is an important link in the process of tunnel construction, normal use and safe operation. Especially in subsea tunnels, the drainage system is particularly important, which is directly related to the success or failure of tunnel construction and the use of functions. [0003] The tunnels built in the past are relatively outdated in terms of drainage concept, drainage materials, drainage technology and equipment, so the drainage system often has the following problems: fine particles in the surrounding rock can easily enter the drainage system, because there is no effective removal Therefore, the drainage system is often blocked; in addition, because the groundwater environment of the subsea tunnel is seawater, it has strong crystallization decomposition compound corro...
