摘要： PROBLEM TO BE SOLVED: To improve workability in inserting pipes to a rock mass and construction precision in constructing a pipe roof.SOLUTION: Each of pipes 10 constituting a pipe roof 5 comprises plate-like members 13 on outer circumferential surfaces at both right and left sides of an upper portion thereof, respectively. When constructing the pipe roof 5, the plurality of pipes 10 are first inserted to a rock mass in such a manner that the plate-like members 13 of neighboring pipes 10 are confronted with each other with a predetermined clearance C1 interposed therebetween. A frozen soil layer 21 is next formed so as to cover above the predetermined clearance C1, in which the predetermined clearance C1 is such a clearance that the frozen soil layer 21 can be self-supported. A high-pressure water jet device is then used to remove sediment between the pipes 10 under the predetermined clearance C1, thereby forming a space 6a. Thereafter, concrete 34 is deposited within the space 6a partitioned by a mold frame 33 and the pipes 10 are connected with each other, thereby integrating the pipe roof 5.

摘要： PROBLEM TO BE SOLVED: To provide a continuous structure of a bridge joint section, which can be constructed in a short period of time, and which enables the smooth passage of a traffic load by enhancing durability, while avoiding an early deterioration in a surface-layer asphalt pavement, by partially suppressing rotational girder displacement of a girder end, associated with traffic loading, and expansion/contraction deformation, associated with a temperature change etc., by means of a partial connection structure, and absorbing the rest of them through the use of deformation performance of a joint member.
SOLUTION: The partial connection structure 11 for partially integrating ends of floor slabs together is formed by placing mortar and the like in notches 10 which are provided in the upper portions of the adjacent RC floor slabs 2 and 2 of a bridge girder 1, respectively. A plate-like precast joint slab 12 is installed on each of the top surface of the partial connection structure and the top surfaces of the right and left floor slabs. The precast joint slab 12 is composed of a highly-tough fiber-reinforced-cement composite material in which vinylon fibers etc. are mixed into a cement matrix, which has high pseudo elongation performance brought about by crack dispersion, and a high tensile/bending deformation capacity, and which is almost equal in vertical rigidity to the RC floor slab. A water proof sheet 14 is provided on the precast joint slab 12, and covered with a paving material 5.

摘要： PROBLEM TO BE SOLVED: To provide a bar arrangement structure reduced in middle hoop reinforcement quantity by laying a middle hoop like a ring via other reinforcing bars and joining both ends of the middle hoop to each other. SOLUTION: A middle hoop 5 formed out of reinforcing bars of small diameter is laid like a ring between a reinforcing bars 3a and 3b, and the end of the middle hoop 5 is self-anchored by use of a crimp terminal 7. In this case, an annealed steel wire of very small diameter is used as the middle hoop 5, and the annealed steel wire 5 is laid in a ring between the reinforcing bars 3a and 3b, and both ends of the wire 5 is thereby bound. According to this construction, the middle hoop 5 is anchored without using a hook and the constraining effect of the middle hoop 5 can be employed nearly to the fracture strength of the base material thereof so that the reinforcement quantity can be reduced.

CONSTITUTION:A hollow pier main body 1 is composed of RC structure wherein all screw- threaded PC steel bars 2 are used as longitudinal reinforcements and high strength concrete 4 is used, the work of setting-up reinforcements is extremely reduced, and the weight thereof is lightened. In the construction thereof, after temporary structural steel members 25 to be buried are installed, a structural steel block A with the all screw-threaded PC steel bars parallel to the longitudinal direction of a pier is set-up, following which inside and outside form units 23, 24 for self-climbing forms 20 are installed and the concrete 4 is placed between the inside form unit 23 and the outside form unit 24. The work of installing the temporary structural steel members, the work of setting-up the structural block A, the work of lifting and installing the self-climbing forms and the work of placing the concrete are repeated in that order, and the construction is done to a specified height. In this way, the usual work of installing and removing scaffolds and forms, inside and outside, is made unnecessary.

摘要： PURPOSE:To correct an irregularity on a connecting face, bring it into face contact, and disperse stress by applying a hardening inhibitor or a foaming agent to a formwork facing the connection face of a large segment, and forming a low-compressive strength thin layer on the surface of a product. CONSTITUTION:When a concrete segment used for a large-cross section shield tunnel or the like is to be manufactured, a concrete hardening inhibitor or a concrete foaming agent is applied in a liquid form to a formwork forming the connecting face of the segment. Concrete is filled and hardened in the formwork. The progress of hardening is delayed or foaming is applied on only the connecting face to form a low-compressive strength concrete thin film. Even when an irregularity is generated on the connecting face by the manufacturing error of the segment or a temperature change, the low-compressive strength concrete thin layer is collapsed by stress concentration to correct the irregularity, and the whole connecting face is brought into face contact. The size error is absorbed, and a water leak can be prevented.

摘要： PURPOSE:To enhance the integrality with main body concrete by providing conical projections to the almost entire surface on the side of main body concrete. CONSTITUTION:An embedding form 1 made of precast concrete is formed by densely providing regular quadrangular pyramid shaped projections 2 to the surface of enabedding form concrete 3. The projections 2 are composed of high compression strength cement mortar and the angle formed by the slope and bottom surface of the regular quadrangular pyramid is set to about 45 deg.. The embedding form made of precast concrete can be easily produced by casting the embedding form concrete 3 into a manufacturing form having reinforcing rods arranged thereto and pressing the press form having regular quadrangular recessed parts carved therein to the surface of the embedding form concrete 3 before the start of curing and transferring the recessed parts to the embedding form concrete 3. By this constitution, the integrality with main body concrete can be enhanced.
