Claims

[Scope of utility model registration request]

In the wall-to-wall connection part of a continuous underground wall, where the previously constructed wall and the later constructed wall of the continuous underground wall are connected via a partition steel plate,
A large number of through holes are provided in the partition steel plate along the vertical direction, and the main reinforcing bars of the previously constructed wall are passed through the partition steel plate through the through holes and extended over a required length toward the later constructed wall. The main reinforcing bars of the previously constructed wall that protrude toward the later constructed wall are overlapped with the main reinforcing bars of the later constructed wall, and the plate surface of the partition steel plate facing the later constructed wall has the L-shaped steel material is welded along the penetration part of the main reinforcing bar,
Further, a truss reinforcement is welded to the L-shaped steel, and the truss reinforcement is welded and connected to the main reinforcement of the previously constructed wall protruding toward the later constructed wall through a reinforcing vertical reinforcement. wall-to-wall connection between continuous underground walls.
