底板与侧墙接茬部位防水做法改进与应用

Improvement and Application of Waterproofing Practices for the Joints of Bottom Plate and Side Walls

底板与侧墙接茬部位,既是工程防水较难解决的部位,也是工程渗漏的常见部位。海南汽摩小镇(G-23地块)项目底板采用预铺式高分子自粘胶膜防水卷材,侧墙采用APF-5000非沥青基强力交叉膜自粘高分子防水卷材(APF-5000),接茬部位在传统做法的基础上进行了改进,搭接效果良好,为同类工程提供了借鉴。

The joint part between the bottom plate and the side wall is not only a difficult part for waterproofing construction,but also a common part vulnerable to leakage.Hainan Automobile and Motorcycle Town(Plot G-23)project adopts pre-laid polymer film reinforced self-adhesive waterproofing membrane for the bottom plate,and APF-5000 non-asphalt strong cross laminated film reinforced polymer self-adhesive waterproofing membrane(APF-5000)for the side wall.The practices of the joint parts have been improved on the basis of traditional methods,and the overlap effect is good.This provides a reference for similar projects.
