本考案は防水性が高く、漏水のおそれのないト

からである。
When constructing a tunnel, it is desired that the completed tunnel not only be strong but also highly waterproof. The reason for this is that if the tunnel is not waterproof, water will seep and drip into the tunnel from the ground above it, and in winter, especially in cold regions,
The water seeping into the tunnel freezes and becomes icicles, which not only hang down from the top wall of the tunnel and cause accidents, but also cause the tunnel itself to freeze and become distorted, and even after thawing, this distortion cannot be completely restored. This is because there is a risk that it will be damaged over many years because it remains untreated.

されている。 Therefore, a waterproof/isolation sheet with a water-permeable cushioning material such as nonwoven fabric, woven fabric, or knitted fabric on the back side is placed directly on the ground excavated in the form of a tunnel or on the surface of the primary concrete constructed on the ground. A tunnel in which the material side is attached and attached has been proposed.

However, in the above-mentioned tunnel, the sheet was attached directly to the surface of the ground or primary concrete using concrete nails, etc., which not only damaged the waterproof surface of the sheet, but also caused the risk of water leakage from there. The pasting work requires skill, and even if a skilled person performs the work, the pasted sheet tends to loosen, and if this slack occurs, the sheet may become rolled up when pouring concrete for the lining. There are problems such as the risk of accidents occurring.

The present invention solves the problems of the conventional technology as described above, and not only allows the waterproof/isolation sheet to be easily pasted without providing through holes, but also allows the sheet to sag after being pasted. It was designed to provide a highly robust and waterproof tunnel by pouring concrete lining, and its structure consists of a male hook-and-loop fastener with a large number of locking protrusions on one side. A plate-shaped supporting member is attached to the primary concrete wall or ground of the tunnel in a dotted, planar, or linear manner with the locking protrusion facing toward the tunnel interior, and a through hole made of nonwoven fabric, woven fabric, or knitted fabric is attached to the back side. A waterproof/isolation sheet provided by laminating water cushioning material is attached by pressing the water-permeable cushioning material side to the locking protrusion of the support member, and a lining concrete is placed on top of the sheet. It is characterized by being made by pouring.

That is, in the tunnel of the present invention, the waterproof/isolation sheet is not attached directly to the primary concrete or the ground, but is first applied to one or both sides of the support member made of the male plate of the hook-and-loop fastener, or the metal plate or synthetic resin plate. A support member provided with a large number of locking protrusions is placed on the surface of the primary concrete or the ground with concrete nails or adhesive in the form of dots, areas, or lines, with the locking protrusions facing toward the tunnel interior. Paste it on the
Next, the water-permeable buffer material side of the waterproof/isolation sheet is pressed against the locking protrusion, and the protrusion is engaged with the water-permeable buffer material to lock it, thereby damaging the waterproof surface of the sheet. By attaching the primary cocrete or the entire surface of the ground without loosening, the concrete lining can be constructed without any problems, and the finished tunnel will be solid and waterproof. It becomes highly sexual.
次に本考案の実施の一例を図により説明する。 Next, an example of implementation of the present invention will be explained with reference to the drawings.

ルの一例が構成されるのである。 Reference numeral 5 denotes a waterproof/isolation sheet in which a water-permeable cushioning material 6 made of non-woven fabric is provided on the back side of a waterproof sheet made of a synthetic resin sheet. The projections 3 are press-locked and adhered to the inner surface of the ground 1, and a concrete lining 7 is cast on the surface of the waterproof/isolation sheet 5 to form an example of the tunnel of the present invention. It is composed.
ここで、面フアスナの雄板には係止用突起とし
て、茸状のものとフツク状のものがあるが、茸状
のものの方が係止力が大きいので、好都合であ
る。 Here, the male plate of the hook-and-loop fastener has a mushroom-shaped locking protrusion and a hook-shaped locking protrusion, but the mushroom-shaped one is more convenient because it has a larger locking force.
尚、通水緩衝材が係止用突起に係止される力が
弱いときは、粘着剤等を併用すれば良い結果が得
られる。 Incidentally, when the force with which the water-permeable cushioning material is locked with the locking protrusion is weak, good results can be obtained by using an adhesive or the like in combination.

選択する必要がある。 On the other hand, although a non-woven fabric was used for the water-permeable cushioning material 6 of the waterproof/isolation sheet 5 in the above embodiment, a woven fabric, a knitted fabric, etc. may also be used. However, in this case, it is necessary to select one that is well-latched to the locking protrusion 3.

て有用である。 The waterproof tunnel of the present invention configured as described above has a support member 2 for adhering and supporting the waterproof/isolation sheet 5 to the ground 1 etc., which is attached to the inner surface of the ground 1 etc. The sheet 5 is attached to the protrusion 3.
By locking the water-permeable cushioning material 6 on the back side, the sheet 5 can be easily and reliably attached to the inner surface of the tunnel without damaging its waterproof surface and without loosening. If there is any slack or tension in a part of the sheet 5, it can be easily and simply corrected by peeling it off and pressing it again, and then the lining concrete 7 is placed on top of the sheet 5.
The work of placing the waterproof isolation sheet is easy, and there is no risk of the sheet getting caught in the lining when pouring concrete, which is caused by the sheet becoming loose, which was often seen when pasting the waterproof isolation sheet. do not have. Furthermore, even if water leaks from the ground 1 after the construction of the tunnel, the water will be discharged outside the tunnel through the water-permeable buffer material 6, and there is a possibility that it will seep into the waterproof side of the waterproof/isolation sheet 5. It is almost non-existent and therefore extremely useful as a highly waterproof tunnel.
本考案は上述のとおりであるから、地山等から
