| This paper summarizes the application of the construction technology of rock socket concrete cut-off wall with hydraulic grab and pure grab method in the construction of many concrete cut-off wall projects and the construction experience of controlling the collapse of slot wall in loose stratum,forming the construction technology for rock socket concrete cut-off wall with hydraulic grab and pure grab method,This slotting construction technology innovates the operation technology to effectively control the slotting hole wall collapse when slotting in loose stratum such as loose fill soil layer,sandy stratum and sandy cobble stratum,etc and the collapse of channel wall in slotting of loose formation can be effectively controlled in the engjneering practice,whose application prospect is promising. |
