PROBLEM TO BE SOLVED: To provide an underground container floating preventing device excellent in workability and draining function capable of preventing an underground container from floating. SOLUTION: An underground container 3 is placed on the upper surface of a cylinder shaped gabion 2 internally filled with stone 1 or crushed concrete pieces, and the container 3 and the cylinder shaped gabion 2 are jointed to each other by use of a connecting member. An underground container separation preventing device is thereby formed. As a result, the separation of the underground container 3 is prevented via the large gravity of the cylinder shaped gabion 2 filled with the stone 1 or the like, and drainage from the lower side of the container 3 is improved by utilizing the good water permeability of the gabion 2 filled with the stone 1 or the like. Also, high workability can be provided because an installation work can be done simply by connecting the container 3 and the gabion 2 to each other with the connecting member 4. |
