Exploration of Comprehensive Construction Technology for Diaphragm Wall under Low Clearance Conditions
The station of Shenzhen Metro Line 13 Phase Ⅱ(North Extension)Project is located under the elevated bridge of Line 6,which has been put into operation.The measured clearance from the bridge to the ground is 13.6 m.In order to ensure the smooth construction of the 25.0 m long diaphragm wall of the station under low clearance conditions in the subway security zone,and to ensure the safe operation of the subway Line 6 track,the low disturbance rapid slotting and steel cage rapid connection construction technology with strong operability and high construction efficiency were adopted.It has a certain reference and reference value for similar projects in the future.
