PROBLEM TO BE SOLVED: To provide an efficient and low-cost construction method for an artificial ground planned at a shallower level than an underground skeleton of an existing structure. ! SOLUTION: Columns, beams, walls and others remain in a space 20 above a batholith part 14 of an underground skeleton 12 of an existing structure. By pouring fluidized soil 30 into the space, a first layer 102 is formed onto which recycled materials 40 including demolished concrete generated in the demolition of the existing structure may be back-filled. By forming a second layer 106 by back-filling the recycled materials 40 including demolished concrete onto the first layer 102 and compacting, an artificial ground 100 capable of supporting a new structure may be constructed easily at low costs, on the batholith part 14. At the same time, the amount of demolished concrete carried out and disposed may be reduced, suppressing the carry-out and disposal costs. Thus, the artificial ground 100 may be constructed efficiently a |
