RAINWATER STORAGE PERMEATING FACILITY

摘要

PROBLEM TO BE SOLVED: To propose a novel method for receiving horizontal earth pressure applied to a rainwater storage permeating facility formed by arranging a storage member. SOLUTION: A storage tank or a permeating tank forms a storage space by covering the periphery with a sheet by assembling storage blocks in an underground space. The storage tank or the permeating tank is characterized by receiving the horizontal earth pressure applied to the tank by a passage, by replacing a storage block part of a peripheral part of the storage space with the passage composed of a material having strength rising from a base of the storage space. The horizontal earth pressure applied to the facility is received by forming a lower layer part of the tank as the passage. The passage is used for a mud reserving part or an inspection.
