Underground building seepage pressure reduction anti-floating structure and construction method thereof
The invention discloses an underground building seepage pressure-reducing anti-floating structure and a construction method thereof, the underground building seepage pressure-reducing anti-floating structure is arranged on a natural foundation, and a blind ditch is arranged above the natural foundation; comprising a foundation device, a drainage system and a waterproof system. The foundation device is arranged on the upper side of the foundation bottom plate; the waterproof system is arranged on the upper side of the blind ditch; the waterproof system comprises geotechnical cloth, a hydrophobic layer, a polyethylene protective film, a concrete cushion layer and a waterproof and waterproof protective layer which are sequentially laid from bottom to top. The drainage system comprises a water collecting well, a water pump, a drainage pipe and a valve; and the water pump is arranged in the water collecting well. By arranging the water insulation system of the drainage system, the problem that an underground building floats upwards can be effectively solved; the device is suitable for water-rich geological conditions, and discharged underground water can be recycled; the operation is convenient, and the construction operation safety is better guaranteed.
本发明公开了一种地下建筑渗流减压抗浮结构及其施工方法，设置于天然地基上，所述天然地基上方设有盲沟；包括基础装置、排水系统和隔水系统；所述基础装置设置于基础底板上侧；所述隔水系统设置于盲沟上侧；所述隔水系统包括土工布、疏水层、聚乙烯保护膜、混凝土垫层和防水及防水保护层，且由下向上依次铺设；所述排水系统包括集水井、水泵、排水管和阀门；所述水泵设置于集水井内部。本发明通过通过设置排水系统的隔水系统，能有效解决地下建筑上浮的特点；且可适用于富水地质条件，且排出的地下水可以重复利用；实施操作便捷，更好保证施工作业安全。
