部材１５の頭部１６が水密的に被覆される。 When attaching the waterproof sheet 1 having the above structure to the primary lining concrete 14 in a tunnel, as shown in FIG.
The waterproof sheet 1 is arranged with the melt spot portion 6 and the second adhesive layer 4 facing the outside (one side of the waterproof sheet 1 faces the primary lining concrete 14). ),
It is attached to the primary concrete lining 14, but when connecting one waterproof sheet 1 and another waterproof sheet 1' to each other, the release sheet 7 of the first adhesive layer 3 of one waterproof sheet 1 is attached to the first waterproof sheet 1. Peel it off, overlap one end of one surface of one waterproof sheet 1 in the lengthwise direction with the other end of one surface of another waterproof sheet 1' in the lengthwise direction via this first adhesive layer 3, and overlap the other waterproof sheet 1. Peel off the release sheet of the second adhesive layer 4' of the waterproof sheet 1', and separate the overlapped portion so that the second adhesive layer 4' of the other waterproof sheet 1' is on the inside (primary lining concrete 14 side).
Next, fold one waterproof sheet 1 so that the melt spot portion 6 is on the outside, and stack the other waterproof sheet 1' on the other end in the longitudinal direction with its second adhesive layer 4' interposed therebetween. It is something to match. Therefore, as a result, the overlapping portion of one sheet 1 and the other sheet 1' and the overlapping portion of the other sheet 1' are bonded to each other through the first adhesive layer 3 and the second adhesive layer 4', respectively. Watertight adhesion occurs due to the action of the adhesive layers 3 and 4'. Also,
The water-permeable sheet 5 of one waterproof sheet 1 and the water-permeable sheet 5' of the other waterproof sheet 1' are the primary lining concrete 1.
4 and are arranged adjacent to each other in a state where they are in contact with each other. In this state, fixing members 15 such as bolts and concrete nails are cast into the primary lining concrete 14 from the melt spot portion 6 through the washer 10 to fix the sheets 1 and 1'. A heated and molten heat-fusible material 17 is injected onto the head 16 of the head 16 using an injection device such as a hand gun, and this heat-fusible material 17 is integrated with the heat-fusible material 11 filled in the frame 9. At the same time, the head 16 of the fixing member 15 is coated with a film of the heat-fusible material 17. Therefore, the head portion 16 of the fixing member 15 is covered in a watertight manner.

い箇所に施工する場合に非常に有効である。 According to the waterproof sheet 1 according to the embodiment described above,
Since the water-permeable sheets 5 are arranged on the primary lining concrete 14 side, spring water from the primary lining concrete 14 side is introduced into these water-permeable sheets 5 and flows inside them. In this case, since the waterproof sheet 1 of the above embodiment has the water permeable sheets 5 laminated in a wave shape, the spring water not only flows through the water permeable sheet 5 but also above the troughs 5a (peaks) of the water permeable sheet 5. 5b) respectively formed between the gaps 5
c and a void 5d formed in the peak portion 5b, respectively.
In particular, these voids 5c and 5d have very little resistance when the spring water flows, so it flows very easily, and a sufficient amount of water permeation is ensured, so it is very effective when constructing in areas with a large amount of water. It is.

が容易で、施工性が非常に良好なものである。 In addition, a waterproof sheet in which a water-permeable material such as non-woven fabric is formed in a flat plate shape on the entire surface of an impermeable base sheet is
If the sheet is to be bent or curved to a considerable degree, even if the main body of the sheet is made of a stretchable material such as an ethylene-vinyl acetate copolymer sheet, the main body of the sheet will be restricted by the water-permeable material and will not stretch sufficiently. On the other hand, even if a stretchable waterproof material is used as a water permeable material, if the main body of the sheet is not stretchable, the water permeable material will be restricted by the main body of the sheet and will not stretch sufficiently. It is difficult to construct because it is not sufficiently curved or bent. On the other hand, the waterproof sheet 1 of the above embodiment has a water-permeable sheet 5
is formed in a wave shape, and the valleys 5a of the water-permeable sheet 5 are bonded to the sheet main body 2 at predetermined intervals (at two valleys in the drawing), and the bonding is partially in the form of point bonding. Therefore, the sheet main body 2 is less restricted by the water-permeable sheet 5, and furthermore, since the sheet main body 2 is made of a stretchable material such as an ethylene-vinyl acetate copolymer sheet, it can be easily stretched. Therefore, when the waterproof sheet 1 is applied to a curved part, it is easy to stretch, curve or bend the waterproof sheet 1 as shown in FIG. 5, and the workability is very good.

By driving the fixing member 15 through the heat-fusible material 11 of the melt spot portion 6, a portion of the head 16 of the fixing member 15 driven through the heat-fusible material 11 is inserted into the heat-fusible material 11. Therefore, when the heat-fusible substance 17 is further injected into the head part 16 of the fixing member 15 using a hand gun or the like, the fixing member 15
A film of the heat-fusible material 17 can be easily formed over the head 16 of the frame 9, and since this film and the heat-fusible material 11 in the frame 9 are of the same quality, they have good adhesion to each other. , a film with good watertightness is formed, and the head 16 of the fixing member 15 is reliably covered with watertightness. Therefore, there is no possibility that spring water will leak from the primary lining concrete 14 side to the secondary lining concrete side through the head 16 of this fixing member 15. Furthermore,
The overlapping part at the end of one sheet 1 and the other sheet 1' and the folded overlapping part of the other sheet 1' are also the first adhesive layer 3 and the second adhesive layer 4', respectively.
Since the fixing member 15 is water-tightly attached,
Even if spring water leaks from the primary lining concrete 14 side along the outer peripheral wall of the primary lining concrete 14, leakage from between the overlapping portions is reliably prevented. Therefore, watertightness is maintained in all parts of the cast part of the fixing member 15, and spring water from the primary lining concrete 14 side is transmitted through the cast part of the fixing member 15 to the secondary lining concrete side. There is no leakage, and one sheet 1 and the other sheet 1' are connected with high watertightness.
