地铁施工中地下车站防水施工技术分析

Analysis of waterproofing construction technology in underground station during subway construction

摘要

由于地下车站经常处于地下水位高、地层含水量大的环境，因此在整个施工和运营过程中都要承受着地下水的压力。从施工现场的经验来看，渗漏水的主要部位集中在施工缝、变形缝、穿墙管、螺栓孔洞及阴阳角等位置，如果没有及时处理，极易出现渗水通道，并且后期维修难度大。为此，我们结合了车站的明挖及暗挖常见渗漏情况，探讨相关的控制措施，旨在提高防水施工质量。

Abstract

Underground stations are frequently exposed to high groundwater levels and saturated strata, subjecting them to continuous pressure throughout construction and operation. Field experience indicates that water infiltration primarily occurs at construction joints, expansion joints, wall-penetrating pipes, bolt holes, and corners. Without prompt remediation, these areas may develop leakage pathways, complicating subsequent repairs. To address this, we analyze common leakage patterns in both open-cut and closed-cut station construction methods and propose targeted control measures to enhance waterproofing quality.
