摘要： PROBLEM TO BE SOLVED: To provide a tunnel widening structure having no adverse effect on a remaining part while reducing required thrust by reducing resistance between the circumferential contact faces (separating parts) of a widening part and the remaining part.
SOLUTION: The tunnel widening structure widens a tunnel by radially pushing out blocks 3a, 3b, 3c of a widening segment 3 in an existing segment ring 1, wherein the mutual contact faces of the pushed-out uppermost block 3a and an upper end 3d of the widening segment 3 left abutting on the circumferential end face of the block 3a are formed into slopes 3aa, 3db allowing the block 3a to be pushed out.

摘要： PROBLEM TO BE SOLVED: To make easy reclamation construction of the sea mainly by soft earth and sand such as construction surplus soil, and curtail the construction cost. SOLUTION: Soft earth and sand for reclamation are carried in a reclamation territory surrounded with outer circumferential revetment 20a, 20b built on the sea bottom face 21, drain materials are laid in the horizontal direction at every fixed depth of the formed soft reclamation ground 26 so as to provide horizontal drains 28 arranged in a plurality of steps in the soft reclamation ground 26, and by draining through the horizontal drains 28, the ground is improved. At carrying the soft earth and soil in, a drainage sand layer 25 along the outer circumferential revetment 20a on one end side of the horizontal drains 28 and vertically continued by burying the one ends of the horizontal drains 28 is formed, a water passage 30 communicated to the inside and the outside of the revetment 20a is provided on a higher position than the sea level WL of the outer circumferential revetment 20a facing to the drainage sand layer 25, a well point 35 is provided on the bottom part of the drainage sand layer 25, and after naturally draining water in the drainage sand layer 25 through the water passage 30, the water is forcedly drained through the well point 35.
