WATER STORAGE FACILITY, METHOD OF CONSTRUCTING WATER STORAGE FACILITY, METHOD OF INCREASING LOAD CAPACITY OF WATER STORAGE FACILITY AGAINST HORIZONTAL LOAD ACTING THEREON, AND METHOD OF PREVENTING HORIZONTAL DISPLACEMENT OF FRAMEWORK BLOCK

摘要

Provided are a method and structure for reinforcing a water storage facility for rainwater, and a framework block unit used therefor.  The method and structure can, without using a special resin framework block, reinforce the water storage facility against a horizontal load.  A framework block (1d) is provided at the lowest stage with supports (5) facing upward, and a framework block (1c) is provided above the framework block (1d) with supports (5) facing downward.  A reinforcing plate (13) is installed on a base plate (3) of the framework block (1c).  A framework block (1b) is provided on the reinforcing plate (13) with supports (5) facing upward.  A framework block (1a) is provided on the framework block (1b) with support (5) facing downward.
