PURPOSE:To allow the ground in which an injected material hardly stays to be surely charged with the injected material such as cement milk by allowing gaps to exist in the ground. CONSTITUTION:The ground E is in a sunk state due to the flowing of soil and sand by the influence of sea water, rain water, etc., and relatively large gaps S1 and S2 are formed between a bank body 12 and the ground E. Into these gaps S1 and S2, a mixture of cemet milk and the water swelling fibers (brand name Lanseal; manufactured by K.K. Toyobo) having the double structure consisting of the inner layer as the core formed by acrylic fibers and the outer layer which is highly water absorptive and arranged so as surround the inner layer and working-processed so as to swell after absorbing water is injected. |
