Abstract

The invention discloses a construction method of a drainage system for preventing leakage of the bottom plate of a tunnel structure, including drainage blind pipes, U-shaped pipe clamps and PVC elbows; the design of the drainage system pipe network: according to engineering buildings, structural construction drawings, drainage Construction drawings; mark and number the tunnel floor expansion joints, longitudinal construction joints, horizontal construction joints and other parts prone to water leakage; carry out elevation measurement for the positions where drainage blind pipes need to be arranged, and design the drainage direction and drainage path; Determine the plane position of the main pipeline and branch pipes, number each pipeline and mark the mileage position; pipeline installation: refer to the designed drainage system drawing to prevent leakage of the tunnel structure floor and water upside down. It can effectively prevent the water leakage from the bottom plate from going up to the structural layer, and use the drainage system to drain the leaking water to the pump room, reduce the treatment cost of the damage to the asphalt structural layer caused by water leakage, and save the cost of plugging and maintenance.

Description

technical field [0001] The invention belongs to the field of tunnel drainage, and in particular relates to a construction method of a drainage system for preventing leakage of the bottom plate of a tunnel structure. Background technique [0002] Tunnel engineering is widely used in projects such as urban expressways, high-speed railways, rail transit, subways, etc. Leakage of underground structures is also a common quality problem in tunnel engineering, and it is also a technical problem. Nowadays, almost all large and small tunnels in China have leakage water condition, [0003] For tunnel water leakage, prevention is usually the main priority, followed by sealing, and then drainage and drainage. After opening to traffic, the leakage water that can be observed by the naked eye can basically be treated by plugging, but it is difficult to accurately find the leakage point and cure the leakage of the bottom plate, so the measures to prevent water leakage are particularly crit...
