市政工程项目中的一些水工、地下构筑物,经常会在伸缩缝处出现渗漏水情况,采用通常做法进行修复时,其施工工艺过程繁杂且影响使用时间长,施工难度大。而采用橡胶打口修复方法,则具有止水过程简单、快速的优势,且修复施工工期短、费用低,具有较好的使用效益。 Some hydraulic and underground structures in municipal engineering projects often have seepage water leakage at the expansion joint. When using the usual practice to repair them, the construction process is complicated and the use time is long and the construction is difficult. The use of rubber mouth repair method, then the sealing process has the advantages of simple, fast, and repair a short construction period, low cost, with good use efficiency.
