In the tunnel construction, to prevent water from underground of the tunnel from leaking from the primary lining concrete side to the secondary lining concrete, the tunnel ground or between the primary lining concrete and the secondary lining concrete It is performed to interpose a waterproof sheet, and as the waterproof sheet,
For example, a laminate in which a water-permeable sheet such as a nonwoven fabric is laminated on one surface of a water-impermeable sheet is used. In order to fix such a waterproof sheet to the ground or the primary lining concrete surface, for example, the other surface of the hook-and-loop fastener having a large number of locking projections formed on one surface is formed in a plate shape such as an iron plate having the same plane shape. One surface of the member is fixed with an adhesive or the like, and the locking projection is disposed on a construction wall surface such as ground or primary lining concrete so that the locking projection faces the inside of the tunnel. After attaching a plurality of hook-and-loop fasteners to the primary lining concrete surface in a dot-like manner so that they are arranged regularly along the length or circumferential direction of the tunnel as much as possible, the nonwoven fabric side It is disposed so as to face the ground or the primary lining concrete surface, and the worker presses and locks the waterproof sheet sequentially from the water-impermeable sheet side of the waterproof sheet to the locking projection of each surface fastener, thereby preventing the waterproof sheet. Stretched the sheet to the primary lining concrete surface, it has been fixed.

ァスナー及び板状部材と共に脱落するおそれがあった。However, it is practically difficult to arrange the hook-and-loop fasteners regularly on the ground of a tunnel or on a construction wall such as a primary lining concrete. When it is pressed, it is difficult to press an accurate position, which is one of the causes of a decrease in work efficiency. Furthermore, since the plate-like member has a flat plate-like shape, the tunnel ground has unevenness and is not flat. Therefore, depending on its mounting position, the fixing strength of the plate-like member to the construction wall is insufficient, and the waterproofing is performed. The sheet may fall off together with the hook-and-loop fastener and the plate-shaped member.

に脱落するおそれもあった。Further, in the case of the conventional fixing member, the weight of the waterproof sheet is applied to the fixing plate via the hook-and-loop fastener and the adhesive. The part of the fastener that is not nailed peels off from the fixing plate, and as a result, the weight of the waterproof sheet is supported by the nail head and the peripheral part of the part that is held by the hook of the hook and loop fastener In such a case, the nail head may pass through the hook-and-loop fastener, and the waterproof sheet may fall off together with the hook-and-loop fastener.

である。The holding member has a band shape narrower than the hook-and-loop fastener, and a plurality of cuts through which the holding member can be inserted into the hook-and-loop fastener are provided at predetermined intervals along the length direction. The holding fastener is attached to the holding member by the holding member being inserted from one surface side to the other surface side at one cut of the surface fastener and being inserted from the next cut to one surface side. If it is, since the surface fastener and the holding member are alternately displayed on one surface side of the fixing member, for example, when attaching the fixing member to the construction wall,
If a concrete nail is driven into a portion where the holding member is exposed on the secondary lining concrete side (inside sky side) of the tunnel, the hook-and-loop fastener is in a state where the concrete nail is driven through the holding member, and the waterproof sheet When the hook-and-loop fastener is fixed, the hook-and-loop fastener is pulled by the weight of the sheet, so that the situation where the head of the concrete nail penetrates the hook-and-loop fastener can be prevented, which is more preferable.

水施工を行う際に有用である。According to the fixing member 1, when the waterproof sheet is stretched and fixed on the ground of the tunnel or the primary lining concrete surface in this way, the hook-and-loop fasteners 2 are regularly arranged in a linear manner. Therefore, when the worker presses the waterproof sheet and engages with the hook-and-loop fastener 2, it is possible to press an appropriate part, and the work efficiency is good, and even if the construction wall has irregularities, it is fixed. Since the member for use 1 is fixed along the longitudinal direction, the fixing strength is also excellent. Further, in the fixing member 1, since the hook-and-loop fastener 2 and the holding member 3 are caulked at a plurality of positions by the caulking member 4, if the concrete nail is driven into the portion where the caulking member 4 is located, the head of the concrete nail is brought to the surface. Since the penetration through the fastener 2 can be prevented, the fixing strength of the waterproof sheet can be further improved. Therefore, the fixing member 1 is useful when performing waterproofing of a tunnel that prevents spring water from underground into the tunnel from leaking from the primary lining concrete side to the secondary lining concrete.
