Abstract:

The rainwater storage tank has the functions of rainwater collection, storage, flood peakavoidance, pollution control and drainage scheduling optimization in the construction of sponge city.However, the modular rainwater storage tank can be used without considering the anti⁃floatingcalculation. When considering the anti⁃floating calculation, the cast⁃in⁃place structure has a longconstruction period, high cost and low profit. An anti⁃floating construction technology of modularassembled rainwater storage tank is proposed. By combining the cast⁃in⁃place structure withmodularization, the application problems of modular rainwater storage tank in areas with high groundwaterlevel and high anti⁃floating requirements are solved. The construction technology is optimized and theconstruction efficiency is improved.
