摘要：PROBLEM TO BE SOLVED: To improve workability while ensuring an intrusion quantity required for the stability of a structure. SOLUTION: A caisson skeleton 10 is provided with side wall sections 12, base plate sections 14 and skirt section 16. The skirt section 16 is provided with fixed and moving tube bodies 16a, 16b having a double structure capable of adjusting the downward protruded length, and the moving tube body 16b is installed vertically movably against the fixed tube body 16a. The downward protruded length, i.e., the axial length, of the fixed tube body 16a is set gradually shorter from the left to the right along the inclination. The moving tube body 16b is a cylindrical body having the same shape as that of the fixed tube body 16a and opened at both ends, it is smaller in diameter than the fixed tube body 16a, and it is stored inside the fixed tube body 16a. When the caisson skeleton 10 is towed, the lock positions of the moving tube bodies 16b are adjusted to keep the lower ends of the moving tube bodies 16b at the same level.
