SOLUTION: A plurality of precast concrete girders 25 are supported in the state of being laid in parallel arrangement between supporting structures 11, erected at a spacing between them, and sections among the precast concrete girders 25 are integrated together for the formation of a flat slab-like object 12. A large number of upward opened sockets 20 are integrally provided at the upper end of the supporting structure 11 in such a manner as to be arranged in the horizontal length direction of the supporting structure 11. A downward protrusion 25a for the insertion of the socket, which can be inserted into the socket 20 in the state of making a gap between the precast concrete girders 25 and an inner surface of the socket 20, is integrally provided on each of the undersurfaces of both the ends of each of the precast concrete girders 25, and inserted into each of the sockets 20 on the supporting structure section 11. A filler 36 is infilled into the gap between the socket 20 and the protrusion 25a, so that the socket 20 and the protrusion 25a can be integrated with each other.

摘要： PROBLEM TO BE SOLVED: To provide a construction method of a bridge, and a side floor slab mounting device for the bridge minimizing restrictions on construction such as traffic regulations without causing an increase in a construction cost or the extension of a construction period.
SOLUTION: A side floor slab 5 is transported into a predetermined position on a main girder 4 by a truck 6. There is thereby no need to lift the side floor slab 5 from a road by a truck crane or the like, nor need to provide an installation space and a working space for the truck crane or the like. In mounting the side floor slab to the side of the main girder 4, the side floor slab 5 is conveyed by a conveying device 13 of the side floor slab mounting device 10, and the fall of the side floor slab 5 is prevented by a fall preventive structure 14. There is thereby no need to limit passing of persons and vehicles below the side floor slab 5 during fixing work. Restrictions on traffic regulations or the like can thereby be minimized on the road or the like below and in a surrounding area below an upper construction 1B under construction, and restrictions on construction can be considerably relieved.

摘要： PROBLEM TO BE SOLVED: To easily and rapidly construct an underground continuous wall having strength equivalent to a general part without using a special device for installing steel members by using the steel members equivalent to the general part, for a lacking part under an underground buried body or the like in constructing the underground continuous wall such as an earth retaining wall of soil cement piles. SOLUTION: A plurality of vertical members 10 of H-shaped cross section are arranged parallel at the predetermined pitch and connected by ties 11 such as flat steel to form a core material panel P1 insertable in an excavated ditch T. A web orthogonal to a horizontal moving direction is formed of a truss to reduce resistance in horizontal movement within soil cement. The core material panel P1 is built up on the ground, hung by a crane and built in the excavated ditch T so as to be located beside the underground buried body A, and then the core material panel P1 is horizontally moved in the excavated ditch T into a position (the lacking part) under the underground buried body A to arrange a plurality of vertical members 10 as stress bearing members in the lacking part.

摘要： PROBLEM TO BE SOLVED: To achieve rational earth retaining work by constructing earth- retaining walls, struts, and intermediate columns within subsoil prior to excavation, in contrast to a conventional method which erects the struts while digging the ground, so that the vertical fulcrums of the earth-retaining walls become clear even in weak subsoil, resulting in a minimized displacement of the earth- retaining walls and cross-sectional forces during excavation. SOLUTION: Using an excavating machine for constructing underground continuous walls, excavation is carried out to a predetermined depth as channeled walls are held by a stabilizing solution, and a reinforcing cage 6 is inserted. Then concrete is placed to construct portions serving as the earth- retaining walls 1, the struts 4 and the intermediate columns 5. Excavation and removal of the struts or nearby unnecessary portions are repeated to complete installation of floors.

摘要： PURPOSE:To raise the efficiency of operation by a method in which a hole is formed in the sheathing wall by using a pipe having a separable bit on its tip, an anchor rod is inserted into the hole, and the pipe is drawn out while packing a solidifying material into it. CONSTITUTION:A hole is formed in a sheathing wall 1 by using a casing pipe 13 having a separable bit 15 on its tip where a check valve is provided in a water-passing hole. After the hole is formed, a reinforcing anchor rod 25 for the sheathing wall 1 is inserted into the ground, and pipe 13 is separated from the bit 15 and drawn out while packing a solidifying material into the hole. The anchor rod 25 can thus be easily set even in hard ground.
