A grouting material (air cement milk, air mortar, etc.) is press-filled between the concrete walls 11 and 11, and backfill grout is applied to the back side of the two-part concrete wall 1 of the side walls 1a and 1a.

なるものである。Conventionally, in a tunnel in which a concrete wall is constructed on the inner surface and a drainage device is provided on the back side of the concave side wall, when central filling grout is applied to the back side of the concrete wall, the drainage device 2 on the back side of the side walls 1a and 1a is closed with grout and the tunnel is closed. The drainage function of the tunnel is not utilized, and spring water at the back of the tunnel appears as water leakage from the concrete joints. This impairs the durability of the concrete, the functionality and aesthetics of the tunnel, and causes repair work.

る。The present invention has been made in view of the above-mentioned defects, and the present invention provides a tunnel in which a concrete wall is constructed on the inner surface and a drainage device is provided on the back side of the concave side wall as described above. A through hole is drilled in the hole, and a mixture of mortar and quick-setting agent is inserted into the upper part of the back of the side wall through the through hole, and after hardening on the upper part of the back, the upper concrete 1 of the side wall is This method applies backfill grout to the back of the concrete wall, so in a tunnel where a concrete wall is constructed on the inner surface and a drainage device is provided on the back of the concave side wall, even if backfill grout is applied to the back of the concrete wall, the side walls 1a, la
There is no risk of the drainage device 2 on the back of the tunnel being blocked by grout, the drainage function of the tunnel is not obstructed, there is no risk of spring water on the back of the tunnel leaking from the concrete 1 or the concrete joints, and the durability of the tunnel is improved. There is no risk of damaging the functionality or aesthetics of the tunnel, and it has the effect of reducing the causes of repair work.
