| 中文摘要:根据场区工程及水文地质和环境条件，选定了武汉市第二医院科教综合楼基坑的防渗止水方案，即单管高压旋喷法，详细阐述了其施工工艺。现场实践证明：所选定的方案截断了上层滞流水体，开挖时坑壁无滴水，为后续工程施工提供了便利；同时单管高压旋喷法施工具有施工简单、造价低、不需要开挖就可以处理隐蔽工程等特点，非常适于城市深基坑的止水与加固。 |

| Abstract:Considering the engineering geology,hydrogeology and environmental conditions in the site of Sciences & Education Building deep foundation pit project of Wuhan No.2 Hospital,the single-pipe high-pressure jet grouting method was adopted to prevent underwater from flowing into foundation pit.The process was depicted in details.The practice proves that this method successfully stopped the flow of upper stagnant water.During excavation,no seepage occurs,which facilitated the subsequent construction.And it also proves that single-pipe high-pressure jet grouting method is very suitable for water-prevention and reinforcement of foundation pit in urban areas because of its convenience of construction,low cost and no need for excavation. |
