摘要
本研究主要介绍深圳太子湾新世界亲子购物坊300m长的地下室疏水层整体系统施工应用。通过对疏水管排布、碎石材料选取铺设、混凝土保护板施工等工序控制,总结出疏水层分段找坡、现浇保护板支撑墩PVC管支模、疏水层直排水系统等创新工艺,现已进行阶段性运行测试,车库地面干爽无水渍,整体设计在后期投入使用后底板主动防水失效的情况下,为地下室创造良好的干燥环境,可为同类高水位、超深超长地下室工程防水施工提供借鉴经验。
This paper introduces the construction and application of the 300 m long basement drainage layer system in the Taiziwan New World Parent-Child Shopping Mall in Shenzhen.Through controlling the drainage pipe layout,gravel pavement,concrete protective plate construction and other processes,a novel process is proposed,including the slope of the drainage layer in sections,PVC tube type support formworks for support piers of cast-in-situ protective plates,and direct drainage system in the drainage layer.At present,the phased operation test has been conducted.The garage floor is dry without any water stains.After the whole system is put into use in the subsequent stage,appropriate dry conditions can be provided for the basement in case of failure of the active waterproofing system at the bottom.This provides a reference for waterproofing construction of similar high-level,ultra-deep and ultra-long basement engineering.
