上海市轨道交通11号线某明挖区段风井防水施工技术

Waterproof Construction Technology of A Vent Shaft of The Cut-and-cover Section of Shanghai Metro 11 Line

介绍了水泥基渗透结晶型防水涂料和聚氨酯防水涂料在上海市轨道交通11号线地下工程某明挖区段风井的防水应用技术,以及细部节点的防水技术。该地下工程地下连续墙与结构外墙两墙合一支护,采用水泥基渗透结晶型防水涂料以加强结构自防水功能,施工简便,解决了施工难度大的问题。

The article introduces Shanghai Metro Line 11 about waterproof construction technology which is using capillary crystalline waterproofing coating and polyurethane waterproofing coating.The＂two walls into one＂ part of the underground construction project is using cementitious capillary crystalline waterproofing materials,which enhances the structural waterproof function,make construction process more simply and much reduced the difficulty of construction.
