Liquefaction countermeasure structure in site

摘要

The present invention relates to a small and medium-sized buildings such as construct inexpensive construction is easy liquefaction countermeasure technology that is suitable for the site of, to provide a countermeasure against liquefaction technology with sufficient effect of pore pressure relaxation. A the upside in the construct of the resin block layer 4 provided in a recess formed by digging the site 1 is constructed structure, a plurality of resin resin blocking layer 4, arranged horizontally It is formed in the block 5. Each resin block 5 is a structural member made of resin (excluding foamed polystyrene) supporting the construct while forming a pore water pressure relaxation spaces S on the lower side of the construct, has an opening so that water can enter the interior. Resin block layer 4 is entirely covered by Saegisuna permeable sheet which transmits the water while blocking the sand ground.FIELD 1
