变形缝渗漏治理施工工艺的研究

Research on Construction Technology against Water Seepage of Deformation Joint

地下工程易发生变形缝渗漏,其成因复杂且对工程正常运行和结构安全影响重大。针对变形缝渗漏治理问题,以汕头市东部城市经济带河口治理及综合开发项目排涝站工程为例,探讨丙烯酸盐、高弹性聚氨酯密封胶、手刮聚脲等治理材料的性能、特点及其在变形缝渗漏治理工程中的使用方法与应用范围,并根据变形缝所处的位置和环境影响要求选择合适的渗漏治理施工工艺,定期跟踪检查表明,渗漏治理效果良好,为处理类似渗漏水治理问题提供解决思路与良好示范。

As a common phenomenon in underground engineering,water seepage of deformation joints is caused by complicated factors and has great influence on normal operation and structural safety.To solve water seepage,the drainage station of estuary governance and integrated development of Shantou Eastern Urban Economic Belt is selected to analyze acrylic salt,high elastic polyurethane sealant and hand-scraped polyurea from the aspects of performance,characteristics,application methods and range.Proper seepage treatment technology is determined according to the location of deformation joint and environmental requirements.Regular monitoring data show good effect.The research will serve as example and solution to similar problems.
