Summary:PURPOSE:To easily control sinking installation by pouring the gas foam liquid containing fine gas foams, between the outer wall of a caisson and the peripheral ground opposed to the outer wall and sinking the caisson. CONSTITUTION:Gas foam liquid 4 is poured into the part between the outer wall 2 of a caisson 1 and the natural ground 3 as peripheral ground, and penetrated into the natural ground 3, and the outer wall 2 of the caisson 1 and the natural ground 3 are set oppositely through the liquid 4 in permeation state. The frictional force between the outer wall 2 and the natural ground 3 as peripheral ground is lightened by the bearing effect of the gas foams which the liquid 4 contains. Therefore, the execution efficiency can be improved.
