Description of the Related Art Conventionally, for waterproofing construction walls of tunnels, primary lining concrete, etc., adjacent waterproof sheets have been connected to each other and stretched on a construction wall such as a tunnel. As such a waterproof sheet, there is known a waterproof sheet obtained by laminating a water-permeable sheet such as a woven fabric or a non-woven fabric on the entire surface of the impermeable sheet. If this kind of waterproof sheet is fixed to the connection end area of the impermeable sheet, it will be connected completely liquid-tight so that water will not leak from the connection point when connecting with other waterproof sheets. Since the work to do is troublesome, as shown in FIG. 5, a waterproof sheet c in which both end portions of the water-impermeable sheet a and the water-permeable sheet b are laminated in a free state is used. While fixing the free end portion b ′ of the water permeable sheet b to the construction wall A by driving the sheet b facing the construction wall A and driving a fixing member d such as a nail into the free end portion b ′ of the water permeable sheet b, Another waterproof sheet c adjacent to the free end a'of the water impermeable sheet a
A waterproof sheet connecting and fixing structure is proposed in which the free ends a ′ of the water-impermeable sheet a are heat-bonded to each other to form an adhesive portion f, and water is stopped at the adhesive portion f (Actual Publication No. Sho 62-3576).
No. 0, Jitsuko 63-2502).

ではかかる問題が生じ易い。However, in this type of waterproof sheet connecting and fixing structure, the spring water from the construction wall A side directly passes through the water permeable sheets b, b to directly connect the water impermeable sheet a. It will flow into (gassho section) f. For this reason, when heat-bonding the adjacent impermeable sheets a to each other, the water flowing down may splash on the operator's face or wet the heat-bonded portion to hinder the heat-bonded portion, resulting in the adhesive strength of the bonded portion. There is a problem that the connection part f is damaged by the weight and the spring pressure due to a large amount of spring water after the construction, and the waterproof function of the waterproof sheet may be impaired. In particular, such a problem is likely to occur in a place with a lot of spring water.

An object of the present invention is to provide a waterproof sheet connecting and fixing structure in which the waterproof function of the waterproof sheet is not impaired even when used in a place where there is a large amount of spring water.

工壁外方の接着部で二重に止水する構造となっている。The structure for connecting and fixing a waterproof sheet of the present invention is the same as a conventional waterproof sheet in which a water-permeable sheet is laminated on one surface of a water-impermeable sheet with both ends of both sheets being in a free state and laminated.
In the first invention, a waterproof sheet is used in which one end of two impermeable connecting tapes is fixed to both ends of the other surface of the impermeable sheet and the other end of each connecting tape is a free end. In the second invention, one end of each of the water-impermeable connecting tapes is fixed to one free end of one surface of the water-impermeable sheet while facing the free end of the water-permeable sheet, and the other end of each connecting tape is attached. A waterproof sheet with a free end is used. Then, while the water-permeable sheet of each waterproof sheet is stretched adjacent to the construction wall, after fixing the free ends of both water-permeable sheets to the construction wall with a fixing member,
In the first invention, the free ends of the water-impermeable sheets of both waterproof sheets are bonded together, and the free ends of the connecting tapes of both waterproof sheets are bonded together to stop water, and in the second invention, , Since the free ends of the connecting tapes of both waterproof sheets are adhered to each other and the free ends of the water impermeable sheets of both waterproof sheets are adhered to each other to stop water, With the connecting tape adhesive portion, the structure is such that water is double stopped at the adhesive portion on the construction wall side and the adhesive portion on the outside of the construction wall.

い。Therefore, when the waterproof sheet is stretched, even if spring water flows down from the construction wall, the spring water from the construction wall side is first blocked by the adhesion portion on the construction wall side. So
When adhering the other connecting tape or impermeable sheet to the outside of the construction wall, spring water has no effect, so there is no risk of water splashing on the operator's face, and the adhering work is easy. At the same time, there is no fear that the adhesive strength will decrease due to water wetting of the adhesive portion. Also, after the installation of the waterproof sheet is completed, even if there is a large amount of spring water from the construction wall, the spring water is double stopped, and the spring water is adhered to the construction wall side. Since water stops and does not reach the adhesive part outside the construction wall, the waterproof function of the adhesive part outside the construction wall is reliable, and even if the adhesive part on the construction wall side is damaged, it leaks. Since the spring water is stopped by the adhesive on the outside of the construction wall, the waterproof function of the waterproof sheet is more reliable, and in this case, the spring pressure is higher than when there is no adhesive on the construction wall. It is prevented from weakening and the adhesive part on the outer side of the construction wall is prevented from being directly exposed to the spring water pressure, and there is very little possibility that the waterproof function of the waterproof sheet is impaired.

ートの防水機能が確実である。According to the waterproof sheet connecting and fixing structure of the above-mentioned embodiment, the spring water from the primary lining concrete side flows down through the water permeable sheet, but is blocked by the adhesive portion of the water impermeable sheet. Therefore, when connecting the connecting tapes together after connecting the impermeable sheet, the spring water from the primary lining concrete side does not reach the connecting tapes, so it does not affect the bonding work of the connecting tapes. Therefore, there is no possibility that the operator's face will be splashed with water or the heat-bonded portion will be wet with water, thereby hindering the heat-bonding and weakening the strength of the heat-bonding. In addition, since the adhesive part where water leakage is likely to occur in the waterproof sheet is double, even if the impermeable sheet adhesive part on the primary lining concrete side is damaged by spring pressure due to a large amount of spring water, Since the leaking water can be blocked by the adhesive part of the connecting tape, and the thermal bonding of the adhesive part of the connecting tape is sufficiently performed without getting wet with water, the waterproof function of the waterproof sheet can be ensured from this point as well. is there.
