摘要

PROBLEM TO BE SOLVED: To provide a construction method for a protective structure against a fallen object, which can obtain greater strength and which can suppress damage to a concrete structure.SOLUTION: A protective structure against a fallen object includes a concrete structure 10, and a retaining wall 20 that is constructed along an impact receiving surface 15 of the concrete structure 10. The retaining wall 20 has step structures 21 that are stacked in plurality of steps. The step structure 21 of each step has a cell assembly 60 that comprises a plurality of flexible cells 61 having each upper part opened, arranged in a honeycomb pattern and integrated with one another, and a filler 70 that is infilled into each cell 61 of the cell assembly 60.SELECTED DRAWING: Figure 1
