Abstract

The invention discloses a waterproof construction method in underground engineering. The waterproof construction method is characterized by comprising the following steps: a, performing tunnel excavation, primary support and waterproof base plane treatment after primary support; b, manufacturing a film spraying material; c, spraying the waterproof base plane by adopting a spray film-forming technology; d, performing reinforcing bar engineering construction; e, performing WEYTHIN cellulose fiber concrete stirring; f, performing WEYTHIN cellulose fiber concrete pouring; and g, forming inverted arch, and finishing waterproof construction during underground engineering. Change of ground water flow rule during underground engineering construction and treatment problem of later tunnel water leakage are avoided. The method is applicable to tunnel water prevention of different lining types and open cut pit water prevention, can reduce the damage of the ground water rule to the greatest degree and is particularly used in regions such as surface water body, wellsprings, geological sensitive areas and the like nearby new projects, extension projects and reconstruction projects. Meanwhile, the cost waste and quality problem caused by subsequent water leakage treatment are reduced.

Description

technical field [0001] The invention relates to the technical field of underground engineering waterproof construction, in particular to an underground engineering waterproof construction method suitable for underground water enrichment areas, karst development areas, coal measure stratum closed areas, and urban ground water sensitive areas. Background technique [0002] In terms of lithology, the rock mass itself is heterogeneous and has characteristics such as different directions, scales, bedding, joints, and fissures. Groundwater drains into the low-level troughs through these fissures, forming groundwater runoff. However, after the excavation process of the tunnel, not only the surrounding rock is inevitably disturbed, but also the cracks in the rock mass are further enlarged, and the weak "pressure" area formed will make the groundwater flow into the tunnel along these cracks. Therefore, the construction of underground works is likely to change the law of groundwater ...
