摘　　要：针对《建筑与市政工程防水通用规范》最新的防水要求,地下室底板一级设防存在自粘卷材复合预铺卷材等不同组合及工艺做法。本文从防水效果、施工便利等方面,对“单面自粘卷材与垫层空铺,粘结面朝上与预铺卷材满粘”(工艺一)与“单面自粘卷材与垫层满粘,预铺卷材空铺在自粘卷材上”(工艺二)两种做法进行了对比分析,并提出改进建议。结论是:工艺一与工艺二各有优势与短处。In response to the latest waterproofing requirements of the “General code for waterproofing of building and municipal engineering”,there are different combinations and process methods for Grade Ⅰ waterproofing of basement floor,such as self-adhesive membrane combined with pre-laid membrane.This article compares and analyzes the two methods:“single sided self-adhesive membrane adhered to the bedding layer at the borders only,and the adhering surface is facing up and fully adhered to the pre-laid membrane”(Process 1),and “single sided self-adhesive membrane fully adhered to the bedding layer,and have border adhesion with the pre-laid membrane”(Process 2),and proposes improvement suggestions.The conclusion is that process 1 and Process 2 each have advantages and disadvantages.
