摘要： PROBLEM TO BE SOLVED: To reform a quay wall without changing the quay wall normal by driving a steel pipe pile deeper than an existing steel sheet pile adjacently to the back of the steel sheet pile, connecting it with a shore, mutually coping the upper ends of the steel sheet pile and the steel pipe pile, and also connecting the shore to the steel sheet pile. SOLUTION: A steel pipe pile 6 is driven adjacently to the back of an existing steel sheet pile 1 more deeply than the steel sheet pile 1 so as to be in parallel thereto avoiding a tie rod 41. In the rear ground, steel pipe piles 8a, Bb are set as braces between steel pipe piles 7. The upper ends of the steep pipe piles 8a, 8b are connected to the upper end of the steel pipe pile 6 by a tie rod 4b. Further, copings 9a, 9b are formed on the upper ends of the steel sheet pile 1 and the steel pipe pile 6 to integrally connect them. The steel pipe piles 8a, 8b are integrated to the steel pipe pile 7 by a coping 9c. Thus, the whole main acting earth pressure acts on the pile 6 by the arch effect of the earth and sand between the piles and also acts on the sheet pile l. Therefore, a quay wall in which the limitation of the quay wall operation can be minimized can be provided.

摘要： PURPOSE:To make the settling work of large-size caisson easier by a method in which the peripheral double wall structure of a caisson is excavated more deeply than the central caisson by a compressed air-type caisson work, and the central part is excavated by an open work under the atmospheric pressure. CONSTITUTION:The peripheral side 3 of a double structure of a caisson is formed to a deeper depth than the central vertical wall 2 of the caisson. The inside of the double wall of the peripheral side 3 is excavated by an excavator with a compressed air chamber 5 by compressed air-type caisson work to construct a bottom slab. Also, the central part 4 is excavated by an open caisson work without bottom slab. The great-depth, large-scale caisson settling work can thus be effectively attained.

摘要： PROBLEM TO BE SOLVED: To enhance the efficiency of underwater tunnel construction work by connecting a plurality of unit box bodies in axial direction with connecting members coupled continuously, neighboring unit boxes are jointed through a water stop material thereby constructing sunk boxes, installing them on sea floor by connecting the sunk boxes together and reducing the section force acting to the sunk boxes. SOLUTION: A plurality of sunk boxes 1 are constructed by interposing a water expandable water stop material 4 having a high expandability to the jointing surfaces of a plurality of the unit box bodies 2, 2 and then jointing them together using a plurality of coupling cables 3, and a sunk box 1 is constructed. Unit box bodies 2a at the end portions of the sunk boxes 1, 1 butted together, bottom portions of both the notched parts are jointed with water stop plates 16, joint fittings 11 are jointed together, concrete 17 is placed in a recessed portion 9 consisting of the notched parts, a water stop grout material 14 is poured into the filled space 13 and is jointed to a rigid jointing state. Coupling between the sunk boxes 1 is in a state of rigid connection, but the unit box bodies 2 forming each sunk box 1 are coupled with a plurality of flexible coupling cables 3 and the water stop rubber 4, so that they are able to freely follow up differential settlement and crustal movement thereby decreasing the section force in the sunk box 1 in order to avoid the occurrence of a great section force.
