有する。In the building construction material of the present invention having the above-mentioned structure, the lattice forming the fiber-reinforced synthetic resin lattice is a fiber bundle in which the respective fibers are bound by a resin material, and a water guide attached to it. Since the material is also strip-shaped, it is extremely lightweight and highly transportable. Moreover, since it is excellent in flexibility, it is easy to install, and it is easy to fit in with unevenness of the water leak surface, and workability during execution is excellent. Further, since it is relatively thin, cement mortar or the like can be applied with a constant thickness. With the building material of the present invention, water leakage that occurs around the building material penetrates into the water-conducting material,
It is guided downward through the voids in the water conduit. Further, since the water-conducting material is provided at a predetermined interval, it is possible to collectively conduct water to a lower part for a certain interval. Concrete and cement mortar have water-stopping properties, and water leakage does not appear on the surface of cement or mortar, but is conducted to the water-conducting material disposed inside concrete or cement mortar. Further, the building construction material of the present invention also functions as a reinforcing member for concrete or cement mortar, and also has corrosion resistance.

Further, in FIG. 1, the strip-shaped water-conducting materials 3 are attached at predetermined intervals along the fiber bundles 1 in the vertical direction of the fiber-reinforced synthetic resin lattice, but are attached not only in the vertical direction but also in the horizontal direction. Alternatively, it may be attached in any direction such as an oblique direction. The attachment direction may be a single type or a combination of two or more types. FIG. 2 shows a state in which the building construction material 4 of FIG. 1 is attached to the inner surface of the tunnel 5, and the building construction material 4 is fixed to the inner surface of the tunnel 5 using staples and anchor bolts. The strip-shaped water-conducting material 3 extends from the ceiling of the tunnel 5 to the lower end of the side wall, induces water leakage to that location, and is guided to the water leakage drainage channel 7 near the lower end of the inner surface of the tunnel 5. This building construction material 4
Cement mortar 9 is applied to the surface of the above to cover the surface of the building construction material 4. This can prevent water leakage from appearing on the inner surface of the tunnel 5. Further, no water leakage will appear on the floor surface 6 of the tunnel.

導くことができる。FIG. 3 is a cross-sectional view showing a state in which the building construction material 4 of the present invention is attached to the leaky rock surface 8 on the inner surface of the tunnel 5 and further covered with cement mortar 9. The building construction material 4 of the present invention is preferably covered with a concrete material such as cement mortar 9. FIG. 4 shows a building construction material 4 in which strip-shaped water-conducting materials 3 are attached in both the vertical direction and the horizontal direction, and more water leakage can be guided.

きる。EFFECTS OF THE INVENTION The building construction material of the present invention is excellent in workability at the time of implementation, and can leak water generated around the building construction material collectively to the lower part to prevent water leakage. Is excellent. Further, according to the tunnel water leakage prevention method of the present invention, the water leakage can be efficiently guided to the lower side wall of the tunnel, and the water leakage from the concrete or cement mortar surface in the tunnel can be efficiently prevented.
