Abstract

The invention discloses a method for chiseling a mid-partition of an underground engineering group pit. The method comprises the following steps: (1) dividing a to-be-chiseled part of the mid-partition and a reserved part of the mid-partition; (2) partitioning the to-be-chiseled part of the middle-partition, chiseling the partitioned middle-partition, and reserving a temporarily reserved part of the middle-partition between the two partitioned blocks in the chiseling process; (3) after chiseling of the partitioned mid-partition is completed, building a permanent constructional column between the mid-partition of the foundation pit; (4) after the construction of the constructional column is completed, chiseling away the temporarily reserved part of the middle-partition; and (5) after the to-be-chiseled part of the middle-partition is completely chiseled, cleaning waste concrete slag, and conducting post-cast strip construction. According to the method for chiseling the mid-partition ofthe underground engineering group pit, in the construction process, the temporary part of the mid-partition is reserved to serve as a temporary bearing structure in the construction process, and safety in the construction process can be well guaranteed. In the chiseling process, the quality of a chiseled hole can be well controlled, and the construction efficiency is high.
