である。 When constructing a tunnel, it is desirable that the completed tunnel not only be strong but also highly waterproof and cold resistant. The reason for this is that if the tunnel is not waterproof, water will seep into the tunnel from the ground above it, and if it is not waterproof and cold resistant, water will seep into the tunnel in the winter, especially in cold regions. Not only does the water freeze and become icicles that hang down from the top of the tunnel, causing accidents, but the tunnel itself freezes and becomes distorted, and this distortion remains without being completely restored even after thawing.
This is because there is a risk that it may become damaged over many years.

る。 First, an appropriate number of mounting holes 11 formed in a waterproof plate support 10 having a stepped shape in which a waterproof plate, which will be described later, is fitted, are provided in the waterproof heat insulating board A. 1 sheet and the joining sheets 8 and 9 in a tunnel t
A water-permeable layer is applied to the ceiling of the surface of the tunnel t to be prevented from freezing in an arch-like direction, and a shallow cup-shaped waterproof tray is provided with a locking collar 12 on the upper periphery of the waterproof tray holder 10. 13, insert a caulking material 14 made of butyl rubber or the like and a flat washer 15 into the bottom of the waterproof plate 13, and then insert an anchor bolt 17 with an anchor member 16 screwed onto the tip of the washer 15, the waterproof plate 13, and the attachment hole. 11 into the hole 18 provided in the tunnel t, rotate the anchor bolt 17, and press the anchor member 16 into the hole 18 for each attachment hole 11, thereby attaching the waterproof insulation board A to the tunnel t. Then, apply the joining sheets 8 and 9 on both sides of this waterproof insulation board A to the wall of the tunnel t, and place another waterproof insulation board on top of them and bend the joining sheets toward the tunnel wall. The work of adhering and bonding to the tunnel t in the same manner as described above is carried out sequentially, and while adhering it in an arch shape to the inner circumference of the tunnel, it is attached to the engaging portion 6 of the lower waterproof and heat insulating board A that has been pasted. The engaging part 7 of the other waterproof heat insulating board is interposed with a caulking material in between to engage and connect in a watertight manner, and if necessary, the joined part of both boards is firmly fixed with staples, and then sequentially upward and laterally. The antifreeze work is completed by joining and fixing the required amount of waterproof and heat insulating boards.

全くない。 As described above, even if water leaks from the upper wall of a tunnel constructed to prevent freezing using the waterproof and heat insulating board A of the present invention, the water flows down through the passageway formed by the void 5 and is discharged to the outside. Therefore, there is no risk of water leaking inside the tunnel, and even if cold wind blows through the tunnel during winter, the cold air is blocked by the protective layer 2 and the insulation layer 1 and is not transmitted to the tunnel wall. There is no risk of the tunnel freezing. Furthermore, since the joints of each waterproof and heat insulating board are sealed watertight, there is no risk of water leaking from these joints.
