SOLUTION: An opening/closing valve 12 for opening/closing an inflow/ outflow opening 15 is provided. A resin liquid A is injected from the outside into a distribution-injector 2 in which a curing agent B is housed in a volume- variable cylinder chamber 23 by a high pressure pump to mix the resin liquid A with the curing agent B. After a resin agent (A+B) for one bag of the variable pad 1 is stored under a high pressure, the distribution-injector 2 is connected to the variable pad 5 placed on the track, and the resin agent (A+B) is pressurized and injected by the movement of a piston 20 in the cylinder chamber 23.

摘要： PROBLEM TO BE SOLVED: To improve efficiency of the spraying work and operability in the point of maintenance in order to enhance resistance of ballast to a sleeper of a ballasted track, in an applicator for spraying a ballast stabilizer which consists of synthetic resin. SOLUTION: A nozzle 5 on which a plurality of discharge holes for ballast stabilizer are opened is attached to the tip of a conduit pipe 4 extended from the storage part 2 for a ballast stabilizer. The nozzle is formed so that a tee pipe connected to the conduit pipe is detachably coupled with a pair of blanched pipes jutted out to right and left, and the discharge holes for the ballast stabilizer are multiply installed in a raw across its nearly entire length at an equal distance. Accordingly, it is possible to efficiently perform the spraying work to the ballast part between sleepers and a ballast part at both shoulder of a sleeper, and at the same time, it is possible to easily perform the removal work of the ballast stabilizer which is adhered and remains on the internal and external surface of the sleepers.

摘要： PROBLEM TO BE SOLVED: To provide a repair material having the required physical properties for repairing a packing layer between a track slab and a base coarse structure and capable of being cured even during the winter, while requiring low cost and providing excellent productivity, and to provide a repair method providing good working efficiency, enabling construction work to be achieved in a short time, and providing a repair layer which is stable in strength. SOLUTION: This repair material is made using a radical-setting synthetic resin as a base material, mixed with fragments of a polymer elastic material and inorganic aggregate with the addition of a curing agent for the base material. In particular, the synthetic resin serving as the base material is composed chiefly of a polyester acrylate, the fragments of the polymer elastic material are rubber chips obtained from the cutting of used tires, and the inorganic aggregate is quartz sand. A repair method involves shaving off the degraded part of a packing layer 4, and packing the repair material A into this shaved part 22. The repair material A is packed while being vibrated using a vibrator 24.

摘要： PROBLEM TO BE SOLVED: To provide an elasticity construction method for a track with track bed which can effectively control various obstructions such as a drop, a loose sleeper, mud pumping and an irregularity of a track due to an excessive impact load acting on the track with track bed and can simply inexpensively construct an elastic structure effective for the reduction of maintenance improvement of a riding comfortableness and the reduction of a noise. SOLUTION: In order to make a track with track bed elasticize, small pieces 5 of polymer elastic material are buried into ballasts under a sleeper 2 with excitation, and then in order to secure the resistance force of a track bed, a track bed stabilizer consisting of synthetic resin is scattered on a track bed part having small buried pieces of polymer elastic material to mutually join a ballast 4 and small pieces of polymer elastic material. A tie tamper is specially used tar burying the small pieces. In addition, a rubber chip formed by cutting an old tire is used as a small piece of polymer elastic material.
