Document Type and Number:
Japanese Patent JPS6018776
Kind Code:
B2
Abstract:
PURPOSE:To obtain a bank body having a large frictional resistance against the outer force by a method wherein the concrete is cast in the upper part of the hull, the hull is turned round by injecting the water in the divisions of the hull, and it is landed on the rubble mound with the surface wherein the concrete is cast touching the mound. CONSTITUTION:The frictional-surface concrete 10 is cast in the upper part of the deck of a hull caisson formed by using the used hull. Next, the water being injected in the divisions 8 of the hull, the hull is turned round so that the frictional-surface concrete 10 is positioned on the lower surface. After that, the sand 4 is thrown in the divisions 8 and thus the hull is sunk so that the frictional concrete surface 10 of the hull caission is landed on the rubble mound 1. The contact of the rubble mound 1 with the concrete surface 10 makes the frictional resistance larger and thus a bank body having large stability against the outer force can be obtained.
