东深供水工程渡槽结构缝缺陷处理技术

Treatment Technologies for Structural Joint Defect of Aqueduct in Dongshen Water Supply Project

针对东深供水渡槽在运行管理过程中出现的两种结构缝缺陷,采取了结构缝清淤、填塞麻绳并在顶面覆盖密封胶、安装不锈钢扁钢压条;U型橡胶止水带打孔、GB板与槽口面粘接、制安结构缝嵌缝板等行之有效的处理技术,为相关工程结构缝缺陷处理提供借鉴。

Aqueduct structure joint has a great influence on the whole stable and safe operation. With the aqueduct serving time going, two kinds of defects appear at the position of structural joint, one is the polysulfide sealant falls off and the other is water stop structure damage. In this study, these two kinds of defects have been introduced, and the defects appeared in dongshen water supply aqueduct joint have been analyzed. Effective treatment technologies are peformed to solve these defects, which would provide reference for related engineering structure joint defects.
