2. Description of the Related Art When constructing an underground structure, a large number of sheet piles are placed at the construction site for the purpose of retaining soil and water, and the mountain retaining wall formed by the sheet piles is agitated and cut into beams. I try to support it. In addition, instead of the conventional excavation method for building underground structures these days,
The so-called upside-down construction method has been adopted.
This method is a method to build a sequential constructs toward the lower floor from the upper floor while excavating a site surrounded by Da設the sheet pile. More concretely, when the excavation for the first basement floor is completed, concrete such as slabs and beams on the first floor is placed, then the excavation for the second basement floor is performed, and at the end of this, the slab, etc. for the first basement floor, etc. in going to build a construct towards the underground in the order of performing the pouring of the method, a relatively wide field and,
It is often used in places where it is requested to shorten the construction period, and in places where there is a concern about ground subsidence .

By the way, in the reverse construction method, sheet piles are driven and excavated to form slabs and the like on each floor. Therefore, vertical and horizontal cut beams are provided to prevent the sheet piles from collapsing. become unable. Therefore, as shown in FIGS. 11 and 12, the slab 1 that has been cast in advance is used to hold the sheet pile.
