上海地铁车站综合防水采用以钢筋混凝土结构自防水为基础与设置诱导缝、施工缝、变形缝、预埋件防水和做好附加防水层相结合的方法,但在地铁车站施工中由于施工不当易出现裂缝、渗漏问题。通过分析地下室结构自防水混凝土渗漏的原因,监理加强对施工单位在混凝土配合比、施工缝设置、施工布料与振捣、预埋件设置、养护与拆模等易出现的质量问题方面进行管理和控制,并提出改进措施,使综合防水工程质量得到保证。
The comprehensive waterproofing of Shanghai metro station adopts the method of combining self-waterproofing of reinforced concrete structure with the construction of induced joints, construction joints, deformation joints, waterproofing of embedded parts and additional waterproof layer. However, due to improper construction in subway station construction Cracks, leakage problems. By analyzing the causes of leakage of self-waterproofing concrete in basement structures, supervision supervises the quality problems of construction units that are prone to occur such as concrete mix ratio, construction seam setting, construction material and vibration, setting of embedded parts, maintenance and demolition of molds And control, and put forward improvement measures to ensure the quality of integrated waterproofing projects are guaranteed.
