UNDERGROUND STRUCTURE PROVIDED WITH A LAYERED RESIN STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2011/037002
Kind Code:
A1
Abstract:
Provided is an underground structure comprising a layered resin structure (30) buried under a road (1), following said road. The layered resin structure is formed by piling up many resin structural members (31), each of which has a space inside, in a plurality of layers. The provided underground structure prevents unevenness and cracks from occurring in the ground surface, which corresponds to the end of the layered resin structure (30), and also prevents the layered resin structure (30) from breaking due to loads from above. In the provided underground structure, a load-distributing material (a concrete slab (13)) is disposed on the top surface of a layered resin structure (30) which is buried under the road (1) and constitutes for example a rainwater-harvesting osmosis tank (10). The load-distributing material is wider than the layered resin structure. The area above the load-distributing material is filled in with a backfill material such as earth or gravel, and the road (1) is laid on top of the backfill.
