压密灌浆技术在处理水工挡土墙裂缝中的应用

Application of Compaction Grouting Technology to Crack Treatment of Hydraulic Retaining Wall

水工挡土墙作为水利工程建设中常用的一种构筑物,其应用非常普遍。当水工挡土墙的高度较高时,会存在着不同程度的裂缝。而这些裂缝严重危害着工程的整体性、耐久性、防渗性及安全运用,因此修复水工挡土墙中的裂缝是十分必要的。本文结合重庆万州某工程特点,主要阐述利用压密灌浆技术处理工程前沿挡墙裂缝,以期为今后类似工程处理提供一定参考。

As a commonly used structure in hydraulic engineering construction,hydraulic retaining wall is widely used.When the height of the hydraulic retaining wall is high,there will be cracks of different degrees.These cracks seriously endanger the integrity,durability,impermeability and safe operation of the project,so it is very necessary to repair the cracks in the hydraulic retaining wall.Combining with the characteristics of a project in Wanzhou,Chongqing,this paper mainly expounds the use of compaction grouting technology to deal with the cracks in the front retaining wall of the project,in order to provide a certain reference for the treatment of similar projects in the future.
