Subway station waterproof and drainage method suitable for soft soil reclamation reclamation area
The invention relates to a subway station waterproof and drainage method suitable for a soft soil reclamation area. The subway station waterproof and drainage method solves the problem that in the prior art, subway engineering in the soft soil reclamation area is affected by the water level. By means of the method, it can be guaranteed that the subway construction process and the subway operation process are not affected by the hydraulic reclamation water level and the underground water level. A hydraulic reclamation area of the temporary clay cofferdam is separated from a subway construction site, a waterproof layer is adopted to prevent hydraulic reclamation water from permeating into the subway construction site, an annular drainage facility is arranged on the inner side of the cofferdam to collect the hydraulic reclamation water permeating into the cofferdam and then pump and drain the hydraulic reclamation water, and a three-axis stirring pile is adopted to separate an underground permeable layer. And the permanent waterproof effect of the station is ensured by spraying of quick-setting rubber asphalt waterproof paint, extrusion molding type polyphenyl polyethylene foam plates and trough concrete backfilling.
本发明为一种适用于软土吹填造陆区的地铁车站防排水方法，其克服了现有技术中存在的软土吹填造陆区地铁工程受水位影响的问题。本发明方法能够保证地铁修建过程及运营过程中不受吹填水位及地下水位的影响。本发明采用临时黏土围堰吹填区域与地铁施工场地分隔，采用防水层防止吹填水渗入地铁施工场地，围堰内侧设置环形排水设施将渗入围堰的汇集后抽排，采用三轴搅拌桩将地下透水层隔断，采用喷涂速凝橡胶沥青防水涂料+挤塑型聚苯聚乙烯泡沫板+肥槽混凝土回填保证车站永久防水效果。
