The specific embodiment

Referring to Fig. 2, shown the double-block type ballastless track structure of the employing resilient sleeper-bearing of the utility model, this structure has adopted the modular structure of sectional type; This structure comprises rail 91, road bed board 92, bed plate 93 and topping 94; Wherein, rail 91 is fixed on the bed board 92 through fastener system and double-block type sleeper, and this road bed board 92 is being provided with geotextiles on the bed plate 93 and between road bed board 92 and the bed plate 93; Be preferably the thick geotextiles of 4mm, bed plate 93 is fixed on the topping 94.

The bottom of every fast road bed board 92 is provided with two shearing-resistant dummy club, then is provided with two corresponding grooves on the bed plate 93, in installation and fixation procedure; The shearing-resistant dummy club correspondence is mounted to (referring to Fig. 3 and Fig. 4) in the groove, and this groove is a rectangle, comprises two long limit A and two minor face B; Around groove, be provided with elastic vibration clamper; Being arranged on the long limit A is first elastic vibration clamper 95, and being arranged on the minor face B is second elastic vibration clamper 96, thus through this shearing-resistant dummy club support bed board with carry out spacing; When train running; Vertical force and horizontal force separately transmit, and horizontal force mainly can transmit through this shearing-resistant dummy club, has improved the support of horizontal direction thus and has improved effectiveness in vibration suppression.

Referring to Fig. 5 to Fig. 9, shown to can be used for going up with resilient sleeper-bearing around the above-mentioned groove that this resilient sleeper-bearing comprises the rubber tile 1 and low density polyethylene (LDPE) 2 that is combined as a whole as elastic vibration clamper; This rubber tile 1 comprises base plate 11 and from these base plate 11 upwardly extending intermediate projections 12; Low density polyethylene (LDPE) 2 is for having the flat board of hollow bulb, and the intermediate projections 12 of the hollow bulb of this low density polyethylene (LDPE) 2 and rubber tile 1 complements each other to form an integral planar, and; The peripheral dimension of this low density polyethylene (LDPE) 2 is identical with the peripheral dimension of the base plate 11 of rubber tile 1; Thus, after both were combined as a whole, rubber tile 1 formed an integral body with low density polyethylene (LDPE) 2; Preferably can combine through bonding, this resilient sleeper-bearing can be trapezoidal with groove around cooperate.

Through such structure, the rubber tile of resilient sleeper-bearing provides vibration-isolating effect, when train passes through rail; Its horizontal direction force is passed in the groove, and the rubber tile elastic deformation of this resilient sleeper-bearing to be providing the effectiveness in vibration suppression to the road bed board, and; Because low density polyethylene (LDPE) and rubber tile are integrally formed, need not to splice when installing at the scene, thereby have simplified mounting process; Improved installation rate, this low density polyethylene (LDPE) has centered on the convexity of rubber tile, thereby when fixing grouting, can avoid water, mortar, aggregate etc. to invade rubber tile; Avoided influence, more be of value to the assurance construction quality vibration-isolating effect.

And for vibration-isolating effect effectively is provided, the intermediate projections 12 of rubber tile 1 must have certain receiving area, therefore; Through a large amount of experiment and designs; The surface area of this intermediate projections 12 is surface area 1/2 to 6/7 preferable of resilient sleeper-bearing, be more preferably, the surface area of this intermediate projections 12 be resilient sleeper-bearing surface area 2/3 to 5/6; Best is, the surface area of this intermediate projections 12 be resilient sleeper-bearing surface area 3/4.

It is obvious that, and above description and record only are to give an example rather than disclosure, application or use in order to limit the utility model.Though described and be described in the drawings embodiment in an embodiment; But the optimal mode that the utility model does not limit by the accompanying drawing example and the conduct of describing is in an embodiment thought at present is with the specific examples of the instruction of implementing the utility model, and the scope of the utility model will comprise any embodiment of the manual that falls into the front and appended claim.
