深基坑水力冲挖与机械开挖组合施工技术研究

Composite Construction with Hydraulic and Mechanical Excavation of Deep Foundation Excavation

武汉长江航运中心采用机械开挖与水泥冲挖船运组合施工技术,将水力冲挖应用到房建领域土方开挖施工中,采用机械开挖空旷区域,水力开挖基坑内撑下狭窄区域,并采用泥浆船运的土方运输方式,解决机械开挖土方运输受限的问题,提高了施工进度,减少了环境污染,取得了良好的社会及经济效益。

Wuhan Yangtze River shipping center uses composite construction of mechanical excavation and cement dredging,in which hydraulic excavation is applied to the field of earth excavation construction. The mechanical excavation is uses for open areas,and hydraulic excavation is used for the narrow area under the support,meanwhile the use of mud transport earth transport is used to solve the problem of mechanical excavation limit,which improves the construction schedule,reduce environmental pollution,and achieve good social and economic benefits.
