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.

摘要： PROBLEM TO BE SOLVED: To integrate a deep foundation pile and the ground and to allow shearing resistance to be considered by cylindrically arranging liner plates each bored with multiple holes on a plate-like section and provided with multiple dowel bars on the surface and back of the plate-like section, evacuating the ground while applying earth retention, and placing concrete to form the deep foundation pile. SOLUTION: Mesh bars are arranged into a curved plate shape, and flanges are provided on and beneath the mesh bars to form a liner plate 1. When a hard rock 15 is excavated after sediment 13 and a soft rock, a liner plate on the uppermost stage 1a is suspended, the uppermost liner plates 1a are connected downward in sequence as excavation progresses, and the liner plates 1 are connected at the portion of a hard rock 15 where the peeling off of a small quantity of rock is merely needed to be prevented and the earth pressure is not required to be considered. The concrete placed in the liner plates 1 after the completion of excavation flows out to the outside from the mesh bars and flows between the hard rock 15 and the liner plates 1, and a deep foundation pile and the hard rock 15 are integrated, thereby the shearing resistance on the side face of the deep foundation pile can be considered.

摘要： PROBLEM TO BE SOLVED: To obtain a large diameter caisson type pile reduced in pile length and reinforcements by connecting one side ends of a plurality of rod members provided protrusively on the peripheral natural ground to reinforcements arranged in the inside of the caisson type pile and then, placing concrete. SOLUTION: Shotcrete and rockbolts 5-1, 5-2, 5-3, 5-4,... are provided in turn while carrying out an excavating work of a ground. The front ends of the rockbolts 5-1, 5-2, etc., are used for anchorage parts 7 and mortar is placed. After excavation, deformed reinforcements 11, hook-shaped reinforcements 15, deformed reinforcements 19, etc., are arranged and joined to the rockbolts 5-1, 5-2, 5-3, etc., with mechanical joints 13, 17 and lap splices 21 respectively. Then, concrete 23 is placed in the excavated part to construct a caisson type pile 25 and bridge piers 27 are constructed on the upper side. Earth anchors or the like can be used instead of the rockbolts. In this way, a shearing resistance between the peripheral face of the caisson type pile 25 and the natural ground can be securely brought out and hence, a large diameter caisson type pile can be constructed.
