EXISTING UNDERGROUND STRUCTURE REINFORCEMENT STRUCTURE, EXISTING UNDERGROUND STRUCTURE REINFORCEMENT METHOD, AND UNDERGROUND STRUCTURE CONSTRUCTION METHOD
Document Type and Number:
Japanese Patent JP2023147050
Kind Code:
A
Abstract:
To provide an existing underground structure reinforcement method enabling construction to be easily performed.SOLUTION: An existing underground structure reinforcement method in the embodiment has a cylindrical wall body construction step to construct a cylindrical wall body 10, which is formed into a cylindrical shape by a plurality of lateral wall members 1 by connecting joint parts 11, 12 formed on both ends in short-length direction of the lateral wall member 1 to each other, around an existing underground structure 8. The cylindrical wall body construction step preferably comprises: a cylindrical wall body erection step to hold the lateral wall member 1 so as to be erected on the foundation, and connect one joint part 11 of the held lateral wall member 1 and the other joint part 12 of other lateral wall member 1 different from the lateral wall member 1, and erect the cylindrical wall body 10 on the ground; and an installation step to sequentially install the plurality of lateral wall members 1 constituting the cylindrical wall body 10 into the ground and install the cylindrical wall body 10 around an existing underground structure 8.SELECTED DRAWING: Figure 5
