摘要
在地下水位较高的区域,下穿道路的地下水渗漏成为亟待解决的技术问题。以合肥某水体周边下穿道路的U型槽结构防水工程为例,从防水设计及施工措施方面入手,介绍了施工缝处理方法、变形缝处理方法、止水胶施工工艺、变形缝施工工艺与外包防水处理措施等内容。项目已竣工多年,尚未发现U型槽侧墙与路面存在渗水、湿迹现象。
In the area of high groundwater level,groundwater leakage under the road becomes a technical problem to be solved.Taking a waterproofing project of U-shaped groove under the road around a water body as an example,from the aspects of waterproof design and construction measures,this paper introduces the construction joint treatment method,deformation joint treatment method,water stop glue construction technology,deformation joint construction technology and outsourcing waterproof treatment measures,etc.The project has been completed for many years,but no water seepage and wet marks have been found in the side wall of u-shaped groove and the road surface.
