No. 60199 and Japanese Patent Publication No. 4-60200. There, a hat-shaped cross-section mounting bracket with a pair of fastening seats on the top and bottom is fixed to the inner wall of the tunnel first,
The wall panels are fastened and fixed to the upper and lower fastening seats, and the wall panels are mounted in a horizontal state in a state of being separated from the inner wall of the tunnel. The back surface of the gap (the side facing the inner wall of the tunnel) is covered with a waterproof sheet made of a polyethylene foam sheet in order to prevent water from leaking from the joint gap between the vertically adjacent wall panels, that is, the horizontal joint. More specifically, a waterproof sheet lined with the wall panel is projected downward from the lower edge of the panel in a hanging manner, and the hanging sheet hem is overlapped on the back surface of the lower wall panel to provide waterproofing. Further, the joint gap between the left and right wall panels, that is, the vertical joint is closed from the back side with a waterproof material having a mountain-shaped cross section, and the front side of the gap is covered with a decorative board. The waterproof material is made of an elastic strip formed of polyethylene foam.

作業は困難を極める。With respect to waterproofing of the horizontal joints, it is difficult to obtain a sufficient waterproofing function by the above waterproofing structure in which the sheet hem is overlapped with the back surface of the lower panel. In detail, the sheet hem made of polyethylene foam is soft and easily deformed, so it is easy to be accidentally scratched when transporting the wall panel or handling it at the construction site, etc. When assembled, water will leak from that area. When joining wall panels, it is easy to knock or fold the seat hem into the panel joint. There is also a disadvantage that the installation is troublesome in addition to the necessity of avoiding such a defective assembly.
Since the seat hem simply covers the rear surface of the panel, there is a possibility that a gap may be formed between the two even after construction. Adhesion of the two can prevent the formation of a gap, but the operation is extremely difficult.

裁にも欠ける不利があった。[0004] In the vertical joint portion, the side end surface of the wall panel is brought into close contact with a waterproof material to perform waterproofing. However, the adjacent distance between the left and right wall panels often fluctuates due to a difference in the level of the panel surface, etc., and when the adjacent distance increases, the panel side end face cannot be brought into close contact with the waterproof material, and water leaks from the gap. There was a fear. In other words, the permissible range of variation at the time of construction is small, and careful attention is required for construction. Since a group of bolt heads for fixing the wall panel to the mounting bracket are all exposed on the panel surface, there is a disadvantage that the appearance of the finished state is lacking.

The back surface of the upper and lower horizontal joints 31 is covered with the water blocking wall 8 of the horizontal drainage board 4. Therefore, even when water leaks down along the back surface of the panel, the water does not enter the joint.
Since the water stop wall 8 is fixedly fastened to the connection seat 10 together with the wall panel 1, the waterproof effect is reliably exhibited even after construction. Since the head of the bolt 20 is located inside the horizontal joint portion 31, the appearance of the wall surface in the finished state is not impaired. Thereafter, by repeating the fastening of the mounting bracket 6 to the inner wall W of the tunnel and the joining of the new wall panel 1 and the fastening to the mounting bracket 6 in order from top to bottom, it is possible to form a panel row along the tunnel peripheral surface, By forming the panel row continuously in the tunnel axial direction, a water leakage prevention wall can be constructed.
