摘要： PROBLEM TO BE SOLVED: To reduce labor for constructing slope concrete, and to shorten the term of works by projecting a plurality of rib sections from the rear of a panel body, burying steel bars to the end sections of the rib sections in the longitudinal direction and box-shaped metal fittings for joining the steel bars at the lower ends of the end sections of the rib sections respectively and burying joining members for joining support bases to the projected end faces of the rib sections. SOLUTION: Concrete panels 1 are installed onto support bases 8 fixed at specified places on concrete. Box-shaped metal fittings 5 for connecting steel bars buried at the lower ends of the end sections of rib sections 3 are coupled and fixed onto anchor bolts by nuts 7. A required number of the concrete panels 1 are arranged in the horizontal direction, the left-right concrete panels 1 are connected mutually, and concrete is placed on the insides of the concrete panels 1. When a concrete slope at a stage upper than the concrete panels 1 by one stage is built, the lower ends of the steel bars 4 buried at the end sections of the rib sections 3 and the upper ends of the steel bars 4 at a lower stage are joined respectively. Upper and lower concrete panel bodies are also coupled.

摘要： PROBLEM TO BE SOLVED: To provide a tunnel structure reducing labor required for concrete panel manufacturing work, reducing the weight of a concrete panel and cost, and bearing shearing force caused by outer load as a composite concrete structure of the concrete panels and post-cast concrete. SOLUTION: The concrete panels 1, 1 are assembled on the predetermined low ground. In assembling, corresponding curved through-holes 2, 2 in the panel ends are allowed to butt each other, and a curved connecting steel bar 3 with thread ridges at both ends is inserted through the through-holes 2, 2. A threaded hole in one end of a nut 4 is screwed with each end of the connecting steel bar 3 and tightened to an anchor plate 5 to carry out bolt connection of the concrete panels 1, 1. A steel bar 6 is screwed with a threaded hole in the other end of the nut 4 to form an anchor reinforcement. A form is built up on the back side of the assembled concrete panels 1, 1, and reinforcements are disposed to place the post-cast concrete 7. After the post-cast concrete 7 is hardened, the form is removed, and banking 8 is constructed at the upper part and side part. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To increase the efficiency of construction work by temporarily assembling together a plurality of lining members into a ring shape for formation of a lining ring, enlarging the diameter of the lining ring to attach each lining member to the natural ground of a tunnel, and filling the joints of the lining members that adjoin to one another in the circumferential direction of the cover ring with a filler. SOLUTION: A plurality of lining members 2 are temporarily assembled into a ring shape inside the tail A of a tunnel excavator to form a ring (a). Next, the lining ring (a) is pushed out of the inside A of the tail of the tunnel excavator into a tunnel 1. Then a widening jack 6 is driven in its expanding direction to widen the lining ring (a) outwards to attach each lining member 2 to the natural ground of the tunnel 1. Then spaces (b) formed by driving of the widening jack 6 are filled with a filler 8. These processes are performed alternately with tunnel excavation to construct the overall length of the tunnel using the lining members 2. Thus the inner periphery of the inside of the tunnel can be lined efficiently and safely.

摘要： PURPOSE: To obtain a surface finishing method of a concrete product by which even when the surface of the placed concrete not yet hardened is not horizontal, a water-base polymer liquid is sprayed to remain on the surface to form a polymer concrete layer of specified thickness in a uniformly mixed state is formed on the surface. CONSTITUTION: After a concrete material is placed in a die and the surface is roughly finished into a curved surface before hardening, lots of small dents 3 are formed like spots on the surface of the concrete segment 2 not yet hardened. Then a water-base polymer liquid is sprayed on the surface so that the polymer liquid temporarily remains in the dents 3 and the surface is finished with trowel to mix the polymer liquid with the concrete. Thus, a polymer concrete layer is formed on the surface of the concrete.
