あるからである。2. Description of the Related Art When constructing a tunnel, it is desired that the completed tunnel is not only robust but also highly waterproof. The reason is that if there is no waterproofness, water will seep and drop into the tunnel from the ground on the tunnel, and in winter, especially in cold regions, the water that seeps into the tunnel will freeze and become icicles, Not only does the tunnel fall down from the upper wall, causing an accident, but the tunnel itself freezes and distorts, and this distortion remains without restoring even after thawing, so it can be damaged for many months. Because there is.

の係止用突起F1に押圧係止させる構造である。[0003] For this reason, many proposals have hitherto been made for a structure for attaching a waterproof sheet to the surface of a tunnel excavated in an arch shape or the surface of a temporary lining formed on the surface. For example, there is a device described in Japanese Utility Model Laid-Open No. 64-10599. As shown in FIG. 5, the waterproof sheet mounting structure according to the present invention is a metal or synthetic resin band or the like having a large number of locking projections F1 formed on its outer surface like a male member of a hook-and-loop fastener. With the support member F having a planar shape, the locking projection F1 is directed toward the inside of the tunnel, and the tunnel is cleared.
A waterproof sheet A having a locked layer A1 formed by attaching a non-woven fabric or the like partially to the back surface while attaching the waterproof sheet A to the wall surface G or the ground in a linear or dot-like manner, A is the supporting member F
Is pressed and locked to the locking projection F1.

それがある。However, in this case, not only the surface of the tunnel excavated in an arch shape but also the surface of the temporary lining constructed on the surface have many irregularities, and it is difficult to mount the support member F at the same height. And, when sticking the waterproof sheet A,
Since the waterproof sheet A is usually opaque, it is necessary to work by hand when pressing the locked layer A1 against the supporting member F, so that the work efficiency is extremely poor and the concave is not good. The locked layer A1 cannot be locked by the support member F attached to the outer portion, so that the locking force of the waterproof sheet A is weakened as a whole, and there is a possibility that the waterproof sheet A may fall off during the work. .

おそれもあるのである。When the support member is attached, a nail or an anchor bolt B or the like is usually used, but the head of the nail interferes with the lock projection of the support member, and as a result, the locking projection F1 which works effectively is used. There is also a possibility that the area is reduced and it becomes difficult to lock the locked layer A1.

On the surface of the primary lining formed on the surface, a water-absorbing material made of nonwoven fabric or the like capable of firmly engaging the male member-shaped engaging projection of the hook-and-loop fastener is fastened, and on the surface of the water-absorbing material,
A waterproof sheet in which a plurality of locking members provided with the locking projections on the back surface are fixed at appropriate intervals in a dot-like manner is attached with the locking projections locked to the water-permeable buffer material. It is characterized by the following.

If a water-cushioning material that firmly entangles and locks the locking projections is adhered, the water-cushioning material has flexibility, so that the water-cushioning material is well adhered to the surface of the tunnel or temporary lining. Therefore, a waterproof sheet having the locking member on the front surface and the back surface with the locking member fixed outward with the locking projections outside is pressed against the water-absorbing buffer material by pressing the locking member on the back surface. By stopping
The present invention has been made from the viewpoint that a waterproof sheet can be firmly stuck to a water-permeable cushioning material, and as a result, a waterproof sheet can be stuck to the tunnel or a temporary lining formed on the surface of the tunnel.

る。1 to 4, reference numeral 1 denotes a primary lining of a tunnel; 2, a water-permeable cushioning material adhered to the surface of the tunnel by driving a nail 3 or the like; It is a flexible material made of a material that can entangle and lock the projecting projections well. At the time of sticking, it is to be constructed at random according to the state of the primary lining 1. Reference numeral 4 denotes a waterproof sheet made of a synthetic resin sheet, and a locking member 5 made of a male member of a hook-and-loop fastener is fixed on the back surface of the waterproof sheet at appropriate intervals in a dot-like manner. A plurality of locking projections 53 each having a head portion 52 formed in a mushroom shape are provided on one surface of a substrate 51.

来る。Since the water-cushioning material 2 is flexible, if it is attached to the primary lining 1, even if the primary lining 1 has irregularities, as shown in FIG. Well familiar and roughly
Thus, the waterproof sheet 4 can be attached by pressing the locking member 5 against the surface of the water buffer material 2.
Is applied, the head 52 of the locking member 5 enters the water buffer 2, the locking projection 53 is entangled and locked to the water buffer 2, and the waterproof sheet 4 is It is stuck without falling off from the water buffer material 2. If a transparent or translucent waterproof sheet 4 is used, the fixing portion of the locking member 5 can be confirmed from its surface, so that the sticking operation can be performed easily and reliably.

のとなる。Further, since the water-absorbing cushioning material 2 and the waterproof sheet 4 adhered as described above have an appropriate slack after being adhered, as shown in FIG. Even if there is a gap a between the water buffer material 2 and when the secondary lining N is cast, they are well adapted to the primary lining 1 surface, as shown in FIG.
Filling it out makes the completed tunnel extremely robust.

る。Further, since the water-permeable cushioning material 2 is directly adhered to the primary lining 1 and the waterproof sheet 4 is adhered on the water-permeable cushioning material 2, the both are separated, so that the weight of the material is reduced. At the same time, it is possible to reduce the cost as a whole because it is not necessary to carry out the bonding work of the both in the factory.

工コストの大幅な低減を図ることが出来る。In the actual sticking operation, a machine for driving and stopping the nail 3 while spreading the water buffer 2 with a spreading machine or the like moving along the arch wall surface of the tunnel is used. After the water-absorbing material 2 is adhered to the waterproof sheet 4 using a similar machine, the locking member 5 is entangled with the water-absorbing material 2 while being pressed against the water-absorbing material 2. If the work is performed using a machine that attaches the waterproof sheet 4 to the surface of the water buffer 2 while adhering the water buffer 2, the construction can be performed quickly. And the construction cost can be greatly reduced.
