High-water-level basement bottom plate lower-layer drainage zone rainwater recycling integrated circulation system structure and construction method thereof

The invention provides a high-water-level basement bottom plate lower-layer drainage zone rainwater recycling integrated circulation system structure. The high-water-level basement bottom plate lower-layer drainage zone rainwater recycling integrated circulation system structure comprises a drainage channel (1), the drainage zone (12), a reservoir (13), a three-stage sedimentation tank (16) and a water storage barrel (18). The drainage channel (1) is arranged below a basement bottom plate (11); the reservoir (13) is arranged outside a soil retaining side wall of the basement; the water storage tank (13) is connected to the third-stage sedimentation tank (16); and the third-stage sedimentation tank (16) is connected into the water storage barrel (18). A construction method of the high-water-level basement bottom plate lower-layer drainage zone rainwater recycling integrated circulation system structure comprises the steps that excavation forming of a drainage ditch is carried out while a foundation platform is constructed, and meanwhile, the reservoir and a rainwater collecting system are constructed. According to the high-water-level basement bottom plate lower-layer drainage zone rainwater recycling integrated circulation system structure and the construction method thereof, the construction water cost is effectively saved, the later bottom plate leakage risk is reduced, the construction difficulty is small, and the safety is high.
