复杂环境下基坑漏水坑内止水加固技术

Water-stop Reinforcement Technology in Leaking Foundation Pit under Complex Environment

结合复杂环境下基坑止水加固工程,介绍了咬合桩加高压旋喷桩止水帷幕的支护形式。根据现场条件,在基坑内侧第三道支撑以下采用RJP工法加固,既加强了止水结构,也兼作底板传力带,从而确保了基坑和隧道安全。可供类似工程参考。

In consideration of foundation pit’s water-stop reinforcement project under complex environment,the paper introduces the supporting methods of the occlusal pile combined with high-pressure rotary spraying with water-stop curtain.According to site conditions,RJP method is used below the third support inside the foundation pit.The reinforcement not only strengthens the water-stop structure,but also serves as the power transmission belt of the bottom plate,which ensures the safety of foundation pits and tunnels.In conclusion,the technology can be used as a reference for similar projects.
