Description

  The present invention relates to a track pavement structure in which a pavement member is installed in the vicinity of a track to form a road surface of the road, and a pavement method in the vicinity of the track that forms a road surface of the road by installing a pavement member in the vicinity of the track. .

  Conventionally, a railroad crossing where a railroad track and a road intersect with each other has been paved to be used for traffic such as pedestrians and automobiles. As an example, although not shown in the figure, there is a railroad crossing in which a covering material made of wood or stone is laid on the inside and outside of two rails (rails). In the case of this paving material, a guard rail is laid between the inner side of the two rails and the laying material, and the space that should be secured by this guard rail so that the wheel flanges of the railway vehicle can pass without hindrance. A “flange way” was formed.

  Further, in recent years, on level crossings where road width is large and road traffic is large, as shown in FIGS. 10 (A) and 10 (B), sleepers at level crossings are removed and reinforced concrete (RC) is used instead. Left and right rails 300 and 300 are respectively provided in two rail receiving recesses 121a and 121b provided on the upper surface of the connecting track plate 121. A railroad crossing pavement structure called a “joint track” that is housed and fastened and supported by mounting bolts 131 and 136 and nuts 130 and 135 is used. Reference numerals 122 and 123 in FIG. 10A are plate-like pavement blocks made of reinforced concrete (RC), prestressed concrete (PC), or the like. In FIG. 10A, symbols F9 and F10 indicate flange ways.

  On level crossings where the road width is large and the road traffic is high, as shown in FIGS. 11A and 10B, reinforced concrete (RC) or prestressed concrete is used without removing the sleepers at the level crossings. (PC) etc., using a plate-like level crossing pavement plate (inner rail side level crossing pavement plate 1, outer rail side level crossing pavement plate 2 and 3), this level crossing pavement plate 201, 202 and 203 is used as a track of the level crossing point. There is also known a level crossing pavement structure (hereinafter referred to as a “soken type pavement plate type level crossing pavement structure”) that paves a level crossing point by being attached to the upper surface of the sleeper T inside and outside.

  As shown in FIG. 11 (B), in this research-type paving plate type railroad crossing pavement structure, each railroad crossing pavement plate (for example, inner rail) is formed by a connecting plate 207 and mounting bolts 291 and 292 that support the rail (for example, 300) from below. The rail-side level crossing pavement plate 201 and the outer rail-side level crossing pavement plate 202) are fixed to the track. In FIG. 11A, reference signs F11 and F12 indicate flange ways.

  In the above-described conventional research-type pavement plate type railroad crossing pavement structure, a rubber chute 284 is installed near the head or abdomen of the rail so as to be parallel to the longitudinal direction of the rail. The rubber chute 284 is a beam-like member having a substantially “K” cross section, and is arranged such that its longitudinal direction is parallel to the longitudinal direction of the rail.

  One of the conventional reasons why these rubber chutes 284 are arranged in the vicinity of the rail 300 is to prevent snow from accumulating in the flange way F11 in the snowfall area and causing the train or the like to “ride and derail”. Met. Also, in recent years, an accident has occurred where an infant gets caught in a rail-containing recess around the rail in the railroad crossing and touches the train, and in order to prevent such personal injury, In order not to leave a recess or a gap other than the flange way, these padding rubber chutes have been used at the crossings. These rubber chutes are made of rubber materials including natural rubber and artificial rubber.

  In addition to the rubber material, a metal material, a synthetic resin material, wood, or the like is also conceivable as a material for the member for filling the gap on the side of the rail 300. However, electrical insulation is required due to contact with the rail, elastic deformation can be used when fitting in a narrow gap, snow and ice are difficult to adhere, impacted snow and ice are hit and elastic deformation accompanying it, etc. A rubber material is used for the reason that it can be easily broken.

  However, since the conventional rubber chute 284 described above has low rigidity and easily deforms, there is a problem in that earth and sand etc. tend to flow downward from between the rubber chute and the connecting track plate and the level crossing pavement plate and accumulate. . In particular, in the Soken-style pavement type railroad crossing pavement structure, when the snow piled up is compressed by the flange of the wheel and becomes icy, the rubber chute 284 falls due to the pressing force from the upper flange. There was also a problem.

  On the other hand, the applicants support a rubber chute with a PC steel rod, and attach a bracket that supports both ends and intermediate portions of the PC steel rod using the fastening bolts and nuts of the rail fastening device of the connecting track, and A method was proposed (see Patent Document 1).

However, with this structure and method, it has often been difficult to accurately install the support bracket and the PC steel bar due to various conditions and errors in the field. Therefore, further improvements in workability on site have been requested.
