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

Abstract

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.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a structure and a construction method of a circulation system for reuse of rainwater in a drainage zone on the lower floor of a basement floor with a high water level. Background technique [0002] With the rapid development of my country's social economy, the application of high-rise residential buildings and underground space is increasing, but the accompanying quality problems are becoming more and more prominent, especially quality problems such as basement leakage, which seriously affect the normal use of basement garages. [0003] The utility model patent with the notification number CN203768988U discloses a basement water resource collection and recycling system, including an underground pool arranged at the bottom of the basement, an outer blind ditch arranged close to the basement of a building, and multiple pools arranged in the basement. The first stage...

Problems solved by technology

[0004] Although this method utilizes shallow water, the drainage path cannot play a role in the construction stage, which increases the difficulty of construction of the underground structure of the building, the quality of the basement waterproofing project is poor, and the uneven settlement of the foundation leads to damage and cracking of the waterproof layer, which in turn causes Structural floor return water leakage
