地铁车站结构渗漏水原因分析及底板渗水治理方式探讨

ANALYSIS OF WATER LEAKAGE CAUSES IN SUBWAY STATION STRUCTURE AND DISCUSSION ON THE TREATMENT METHODS OF FLOOR SEEPAGE

从车站结构赋存地质环境、设计、施工及工程质量等方面分析地铁车站结构渗水原因,采用以丙烯盐酸为主要材料,对车站结构底板渗水进行注浆堵漏治理;根据渗水方式、渗水位置的不同,提出3种不同的注浆孔布置方式,实践表明,上述注浆材料与注浆孔布置方式能够有效解决车站结构底板渗水问题,为以后车站结构底板渗水病害治理提供参考依据。

This paper analyzes the causes of water seepage in the subway station structure from the aspects of the geological environment,design,construction and engineering quality of the station structure,and uses propylene hydrochloric acid as the main material to grouting and plugging the seepage water at the bottom of the station structure.According to different seepage locations,three different grouting hole arrangements are proposed.Practice has proved that the above grouting materials and grouting hole arrangements can effectively solve the problem of water seepage at the bottom of the station structure,and provide a reference for the treatment of water seepage diseases on the bottom of the station structure in the future.in accordance with.
