業能率が向上する。As described above, according to the all-weather construction method for underground construction of the present invention, the traveling rail is laid on the mountain retaining wall, the traveling rail is attached to the boarding gantry, and the traveling rail is laid across the traveling rail. A retractable temporary roof that opens and closes in the horizontal direction is movably provided, a water collecting sheet is laid under the boarding gantry, and a drain hose is provided at an appropriate location of the water collecting sheet to perform underground construction. As a result, the underground construction can be continued even in rainy weather, and the construction period can be shortened. Moreover, since the temporary roof can be installed by simply laying the traveling rails on the existing mountain retaining wall and boarding gantry, all-weather construction can be performed at low cost. Since the temporary roof is extendable and movable on the traveling rail,
It does not hinder the operation of the lifting machine and can be operated even in the rain, improving work efficiency.
