【摘要】 重庆轨道交通3号线红旗河沟车站隧道防排水采用BAC高分子自粘性橡胶沥青防水卷材全包防水。为保证防排水施工质量,在铺设卷材前,设置纵、环向排水盲管,并进行防水基面处理。在检查卷材质量后,对防水卷材进行悬挂固定、接缝连接,最后进行施工质量检验与修补。红旗河沟车站隧道防排水施工及二衬模筑后,车站隧道二衬混凝土面无渗水和湿渍现象发生,防排水效果良好。更多还原

【Abstract】 The BAC polymer self-adhesive waterproofing coiled material is used for whole encapsulation waterproofing and drainage in Chongqing subway line 3 Hongqihegou station tunnel.Before the coiled material is laid,the horizontal and vertical blind pipes are set up and the waterproofing layer is treated to assure the construction quality of waterproofing and drainage.After the quality of coiled material is guaranteed,waterproofing coiled material is hoisted,fixed and connection in the joints.Then construction quality is inspected and remedied.After the construction waterproofing and drainage and secondary cast-in -situ concrete lining are ensured,the seepage and permeable at concrete surface have not occur in the station tunnel.The technology has a good effect for waterproofing and drainage.更多还原
