Description of the Related Art Conventionally, a temporary shutter is installed at the entrance of a temporary enclosure that is temporarily installed at the boundary of a construction site to prevent outsiders from entering the site. It is very heavy because it is wide and tall for loading and unloading large vehicles, civil engineering equipment and materials, and because the shutter body is installed between the upper ends of a pair of pillars, the center of gravity is above. Is unbalanced and therefore requires construction of a large-volume foundation to support the temporary shutter, and detailed structural calculations are required to prevent accidents such as the temporary shutter being collapsed, which is very troublesome. It was

全面的に掘削する様にして行っている。Further, at the construction site, in order to construct a building foundation and an underground structure, total root cutting is performed to excavate the site slightly wider than the first floor, and the collapse of the excavated wall surface during such excavation is prevented. Prior to excavation, the pile retaining method is performed by driving a large number of piles around the planned excavation area at a predetermined interval and entirely excavating the inside by a clamshell, a power shovel, or the like.

構築するスペースが無く、対応に苦慮していた。However, since recent buildings are often built on the edge of the site, the excavation section is naturally on the edge of the site.
As a result, there was no space to build a large-volume foundation for the temporary shutters, and it was difficult to deal with them.
