Abstract

The invention discloses a tunnel construction water recycling system and belongs to the technical field of tunnel construction. The problems that sewage produced in tunnel construction is likely to pollute environment, and a large amount of waste is caused are solved. The system comprises a filtering sedimentation basin composed of primary filtering sedimentation areas and an ultimate filtering sedimentation area. The primary filtering sedimentation areas collect sewage for construction through a drainage system and comprise the first-level filtering sedimentation area, the second-level filtering sedimentation area and the third-level filtering sedimentation area. The first-level filtering sedimentation area, the second-level filtering sedimentation area, the third-level filtering sedimentation area and the ultimate filtering sedimentation area are each provided with a desilting opening and a mud removal opening and adjacently connected through filter openings. In each sedimentation area, the height of the corresponding desilting opening is smaller than that of the corresponding mud removal opening. Impurities in water for tunnel construction and underground water are removed through filtering and sedimentation, it is ensured that water for tunnel construction is recycled, and the problems of environment pollution, city sewage pipe blockage and the like caused by tunnel construction wastewater are solved.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction, and specifically relates to a system for recycling groundwater and sewage generated during tunnel construction. Background technique [0002] At present, my country's urban water consumption is becoming more and more scarce, and water resources are becoming more and more scarce. Therefore, during the tunnel construction, the amount of tunnel construction sewage generated is quite large. The tunnel construction sewage mainly includes bedrock fissure water, sewage generated by drilling rigs and The sewage generated in the concrete spraying, pouring and curing process and the sewage generated by the flushing equipment, if only the sewage from the tunnel construction is simply discharged, it will not only cause great pollution to the environment, but also cause a lot of waste. Therefore, on the premise of satisfying the construction water consumption, how to improve the reuse rate of const...
