摘要： PROBLEM TO BE SOLVED: To provide a direct-coupled track structure in which the fatigue strength of a subbase course composed of a cement curable material is increased by optimizing the mixing ratio of short fibers and the breakdown of the subbase course can be prevented. SOLUTION: In the direct-coupled track structure in which a section between a concrete floor slab 1 and a sleeper 2 is connected by the subbase course 3 consisting of the cement curable material such as concrete, mortar or the like, the short fibers at a volume ratio of 1 to 5% are mixed in the cement curable material constituting the subbase course 3. When the mixing ratio of the short fibers is set in 1% or more, the tensile stress of concrete or mortar is suddenly reduced temporarily immediately after the generation of a crack but it is changed abruptly into an increase temporarily, thus augmenting fatigue strength.

摘要： PROBLEM TO BE SOLVED: To provide long term stabilization of a prestressed concrete tie and provide an inexpensive solid bed track with the prestressed concrete tie. SOLUTION: Insulating members 20 are attached to both end parts of the prestressed concrete tie 11, and both end parts of the prestressed concrete tie 11 is supported on track bed concrete 12 via the insulating members 20. The insulating member 20 is formed by inexpensive synthetic rubber, and it comprises a first cushioning material 21 covering a bottom face 11a below a rail 13 in the prestressed concrete tie 11 and both side faces 11b, a second cushioning material 22 covering both end faces 11c, and a third cushioning material 23 arranged between the bottom face 11a, both side faces 11b and both end faces 11c.

摘要： PROBLEM TO BE SOLVED: To provide a rail fixing nail capable of simplifying a structure while sufficiently securing tightening force and lateral resistance and tightening a rail by a simple construction method. SOLUTION: The rail fixing nail is composed of a pair of leg parts 11 formed to bend a linear material and driven into a sleeper 10, a depressing part 13 depressing the bottom part of the rail and fixed on a sleeper, and a connecting part 14 for connecting the depressing part and the upper end of both the legs. The rail is depressed and tightened on the sleeper by utilizing the elasticity of the connecting part by pressure-contacting the depressing part on the bottom part of the rail while elastically deforming the connecting part by driving both the leg parts into the sleeper.

摘要： PROBLEM TO BE SOLVED: To provide a pad and a construction method for elasticizing a track, which allow effective repair of places of various failures occurring on the track due to a decrease in elastic bearing capacity, which exert an effective influence on a reduction in maintenance work and an improvement in riding comfort, and which easily establish track maintenance at a low cost. SOLUTION: The pad 15 for elasticizing the track, which is used for the construction method for elasticizing the track, is equipped with a bag-shaped pad body wherein at least a part on the side of a top surface has permeability and wherein at least the side of an under surface has impermeability, an elasticity adjusting material which is composed of small pieces of a polymer elastic material presealed in the pad body in a state of uniform dispersion, and a resin injection part wherein a curable elastic resin material is post-injected, in a pressurized state, into the pad body inserted on the side of a bottom of a tie.
