Regarding the water-stop coating method for the tunnel wall surface, which is to guide all water leakage and spring water from the concrete wall surface of the tunnel arch to the road side gutter and prevent the leakage water and spring water from falling onto the road surface inside the tunnel, Compared to this type of water-stop coating construction method, material costs and construction costs can be significantly reduced, and by strengthening the adhesive strength of the mortar used for water-stop coating to the tunnel wall, secondary damage caused by detachment of the covering mortar can be prevented. The present invention relates to a construction method that prevents this occurrence and significantly increases the durability of this coating.

ものである。 As shown in Figure 1, in a road tunnel,
Vertical grooves 2,
2', and the vertical grooves are sealed with water-stop sheet lids 5, 5'..., and on the back side of the band-shaped non-water permeable plastic sheet 12, as shown in Fig. 5, in the longitudinal direction. A felt-like sheet 13 made of water-permeable plastic fiber is sewn 19 with some slack, and a sturdy coil-like hollow core body 14 made of hard plastic that does not easily deform is inserted into the slack part. Therefore, the water-stopping strip sheets 4, 4', which are arranged while forming the water-permeable leakage collection and drainage pipes 3, 3', are used to cover the water-permeable leakage collection and drainage pipes 3, 3',... The fourth groove has an appropriate downward slope toward the vertical grooves 2, 2', so that one end thereof is open to the vertical grooves 2, 2', and so on.
As shown in the figure, the permeable leakage collection and drainage pipes 3, 3'...
A waterproof packing 9 is placed on the back side of the non-water-permeable plastic sheet 12 along the bottom of the arch, and a backing plate 15 is pressed onto the concrete wall 1 of the arch section from the front side of the plastic sheet 12. The water stop packing 9 is attached to that position in a pressed manner to prevent water from leaking downward, and is partially attached to the concrete wall surface 1 of the arch part so as to exclusively cover the water leakage part. This is a waterproof coating method in which a metal steel 6 is then laid over the entire surface of the concrete wall surface 1 of the arch portion, and mortar 7 is sprayed onto the entire surface to cover the entire surface with new mortar. In addition, drawing code 16 is shown in Figure 4.
The one shown by is easy to collect leakage water flowing down through the arch concrete wall surface 1 of the part to which the water stop band sheet 4 is not attached to the permeable leakage collection and drainage pipes 3, 3', etc. In order to do this, the permeable leakage collection and drainage pipes 3, 3'... of the water-stopping strip sheet 4 are inserted between the upper side and the concrete wall surface 1 of the arch section, and are made of tangled strings of coconut pine or plastic fibers. It is a pillow board with high water permeability that is similar to the body, and the chain lines in FIG.
The figures should be appropriately arranged on the concrete wall surface 1 of the arch part so as to cover actual water leakage points, and should not be arranged according to a fixed arrangement design. In addition, FIG. 6 shows a water-stop sheet lid 5 for sealing the vertical grooves 2, 2'...
The details of the back side of an example are shown, and the ribs 17 for structural reinforcement, which are vertically parallel and protruding on the surface of the plastic sheet, are not visible even when the sheet lid 5 is closely fixed to the concrete wall surface. Rib 17
Therefore, a longitudinal flow path is automatically interposed between the concrete wall surface and the sheet lid 5, and is configured to facilitate the flow of water along the wall surface due to leakage.

共にトンネル自体の構造をも補強する効果を発揮
する。 In a tunnel with water-stop coating as described above, spring water or water leakage that comes out to the wall surface 1 through cracks in the concrete wall 11 of the arch portion is covered by the water-stop band sheet 4, 4'... and the water-stop packing 9 prevent it from leaking to the outside, and the water leaks into the inside of the permeable leakage collection and drain pipes 3, 3'... and passes through the inside of the water-stop sheet lids 5, 5'... The water is discharged into the sealed vertical grooves 2, 2', and then naturally discharged from the vertical grooves 2, 2' to the road gutter (not shown), causing spring water and leakage to occur on the road surface inside the tunnel. On the other hand, since the attachment of the water-stopping strip sheets 4, 4', etc. to the concrete wall surface 1 of the arch section is limited to the leaking area, water dripping onto the concrete wall surface 1 in other parts beyond that can be completely prevented. As a result, the adhesion strength of the mortar 7 layer to the wall surface 1, which is sprayed next, is directly bonded to the wall surface 1.As a result, the adhesive strength of the 7 mortar layers to the wall surface 1 is lower than that of the conventional concrete wall surface 1 of the arch section, for example, as shown in FIG. Compared to a method in which a sheet is laid and then mortar is sprayed, and there is no direct bonding between the sprayed mortar and the concrete wall surface 1 of the arch, the strength and durability of the water-stop coating is significantly increased. In addition to increasing the strength of the tunnel, it also has the effect of reinforcing the structure of the tunnel itself.
またアーチ部コンクリート壁面１に対して部分
的に止水工作を施こすだけであるから、前述した
ごとき全面的に止水工作を施工する従来のものに
較べて工数及び資材の節減に資す効果も甚だ顕著
である。 In addition, since the concrete wall 1 of the arch section is only partially water-stopped, it has the effect of reducing man-hours and materials compared to the conventional method of performing water-stopping work on the entire surface as described above. It's extremely noticeable.
