CONSTRUCTION METHOD OF UNDERGROUND CONTINUOUS WALL
Document Type and Number:
Japanese Patent JP2023147465
Kind Code:
A
Abstract:
To provide a method capable of smoothly performing excavation of an excavation pit for a following element, without performing filling work of gravel and crushed rock.SOLUTION: A construction method of an underground continuous wall comprises the steps of: forming a preceding excavation pit 4 by excavating natural ground; installing, on a side of constructing following elements 3 of the preceding excavation pit 4, partition plates 10 having a dimension in a depth direction of the preceding excavation pit 4 shorter than the depth dimension of the preceding excavation pit 4; constructing preceding elements 2 by placing concrete to the preceding excavation pit 4; removing the partition plates 10; forming a following excavation pit 5 by excavating the natural ground between the preceding elements 2, 2 from which the partition plates 10 are removed; and constructing the following elements 3 integrally with the preceding elements 2, by placing concrete to the following excavation pit 5. After constructing the multiple preceding elements 2 as wall bodies in the ground, the following elements are constructed between the preceding elements 2 to construct a continuous wall 1 in the ground.SELECTED DRAWING: Figure 1
