提高地铁暗挖区间EVA防水板隔水效果措施研究

Research on optimization measures for water insulation effect of EVA waterproof board in subway engineering

EVA防水板对地下水和混凝土结构能够进行有效隔离,提高防水效果的同时保证结构的耐久性。在地铁施工过程中,渗漏水现象较为常见,此类情况易危及地铁运行安全、降低乘客乘坐舒适性、增加后期维修堵漏成本。文章通过提高基面处理质量,优化EVA防水板完整性,保证混凝土结构不被地下水侵蚀,达到延长区间隧道使用寿命的目的。

EVA waterproofing board can effectively isolate groundwater and concrete structures,improve the waterproof effect and ensure the durability of the structure.In the process of subway construction,water leakage is more common,which can easily endanger the safety of subway operation,reduce passenger comfort and increase the cost of later maintenance and plugging.By improving the quality of base surface treatment,optimizing the integrity of EVA waterproofing board,ensuring that the concrete structure is not eroded by groundwater,and achieving the purpose of extending the service life of the interval tunnel.
