New Low-carbon and Environmentally Friendly Hydraulic Construction Technology of Large Ship Lock Foundation Excavation
In response to the problems of conventional mechanical excavation of ship lock foundation excavation involving multiple equipments,high noise,high energy consumption,as well as the significant impact of earthwork transportation on the environment and road safety in the urban area,and the impact of urban traffic control on the construction period and so on,relying on Babao Ship Lock project of Beijing-Hangzhou Canal,a complete set of foundation excavation construction technology is developed,including hydraulic excavation and slurry making,long-distance pumping of cement slurry,tertiary sedimentation of cement slurry,recycling of sedimentation water bodies,and transportation of waste soil by waterway.A new green and low-carbon hydraulic construction technology is formed for large-scale ship lock foundation excavation.This process enriches the construction technology of water transportation engineering foundation excavation,achieves the promotion of green and low-carbon development through green technology.
