水性の向上を図つている。 In a continuous underground wall formed by connecting unit walls, each unit wall is connected via a joint, so when used as a water-shielding wall, water-stopping performance at the joint portion becomes a problem. Therefore, attempts have been made to improve water-stopping properties by adopting joint structures that increase the contact area between the joint and concrete, and by applying waterproofing treatment to the joints.

と継手端部とを被覆してなる。 This invention for the above purpose consists of a unit wall that is first cast into a plurality of long holes drilled into the ground at required intervals, and a unit wall that is drilled after the long holes that are drilled between the unit walls. In a continuous underground wall connected through a joint, a water-stopping sheet is applied along a part of the hole wall surface and a part of the hole bottom surface over a pair of joints located at both ends of the precast unit wall, and the water-stop sheet is attached to the joint end. The joints on both ends of the water-stop sheet are inserted into the guide member protruding from the outer end of the joint, and the water-stop sheet of the post-cast unit wall is fitted into the guide member protruding from the outer end of the joint. The joint end is covered with the wall surface of each unit wall cast in the joint.

どの特長を有する。 As mentioned above, this idea involves providing a water-tight sheet that extends over the joint along part of the hole wall and bottom surface, and is watertightly fixed to the end of the joint. The end of the joint is covered along with the wall surface of the unit wall of the inner wall, and as a result, the entire underground wall is provided with water-stopping properties, so the structure of the joint part is extremely simple, yet it has good water-stopping properties.
Even if cracks occur in the wall and joint parts after a long period of time, the water-stop properties can be maintained as long as the water-stop sheet is not damaged. In addition, since no other special measures are required simply by attaching the water-tight sheet to the joints, construction is easy, and the joints bond well with the concrete, without damaging continuity. have
