新规下预铺防水卷材的搭配应用分析与测试研究

Analysis and Testing of Pre-laid Waterproofing Membranes Application under New Regulations

GB 55030—2022《建筑与市政工程防水通用规范》的正式实施,对于预铺防水卷材在明挖地下底板防水中的应用产生了较大影响,本文主要对新规实施后预铺防水卷材可能出现的搭配材料及做法进行分析,并对其相容性和长期粘结效果做了试验测试,提出了相对合理可行的预铺防水做法搭配建议。

The formal implementation of GB 55030—2022“General code for waterproofing of building and municipal engineering”has had a significant impact on the application of pre-laid waterproofing membranes in the waterproofing of open cut underground bottom plate.This article mainly analyzes the possible matching materials and practices of pre-laid waterproofing membranes after the implementation of the new regulations,conducts experimental tests on their compatibility and long-term bonding effect,and proposes relatively reasonable and feasible suggestions for combined practices of pre-laid waterproofing.
