Description
Technical Field
The utility model relates to a rail transit technical field especially relates to a fastener cover, fastener system and track suitable for tram.
Background
Trams typically employ an embedded track structure in which a fastener system is used to secure the rails. The fastener cover shields the fastener system from being polluted and eroded by external rainwater and from being extruded or buried by soil asphalt and the like, so that metal parts of the fastener system are not corroded; meanwhile, the fastener system is prevented from being submerged by cement in a cement pouring stage in the construction process, and when the track structure reaches a maintenance period, the fastener system can be smoothly disassembled and replaced. In addition, the fastener covers the below pitch layer and is thinner, and the social vehicle that the intersection passed through frequently is easy with pitch layer fracturing, and the fastener covers certain elasticity, can provide the buffering for pitch layer, alleviates this problem to a certain extent.
However, social vehicles on the cross-buckled section come and go frequently, particularly, the traffic flow is high at some large intersections, and vehicles with large loads such as heavy trucks often appear. The fastener cover often can't bear long-term, great load and the fracture damage leads to road surface pitch to cave in, appears the semicircular crackle and the pit of interval rule at the circuit edge line, influences social vehicle and passes. The damage of the road asphalt causes the rail top sealant beside the steel rail to lose support, and the rail top sealant is taken away from the original position by the wheels of the social vehicles, so that rainwater dirt leaks downwards, and the sealing, insulation and corrosion prevention of the rail structure are not facilitated.
Therefore, the fastener cover has both certain elasticity and sufficient pressure-bearing capacity, which has high requirements on the material used, and cannot meet the use requirements due to the limited product cost. To the problem of the cracking of the fastener cover at the intersection, two solutions are provided in the current engineering, wherein the first solution is to dig out the damaged road, replace the fastener cover, pave the asphalt on the road surface, and finally repair the rail top sealant. The method cannot solve the problems fundamentally, requires irregular maintenance, has higher cost of manpower and material resources, and can affect the social vehicle passing more or less during maintenance. The second scheme is that in the construction period of a new line, a fastener cover with good pressure bearing performance is adopted at the intersection section, and obviously, the second method is more beneficial to the development and gradual improvement of the fastener cover. However, the prior art fastener covers still have a plurality of problems.
Through the search, patent document CN108149528A discloses a hemispherical rigid cover, the structure and the optimization of the material of which both increase the pressure-bearing capacity, but the overall height of the fastener cover increases, so that the asphalt layer above is thinner, and the rigid material can not provide buffer for the asphalt layer, so that the asphalt layer is weaker, and is more easily damaged and cracked, thereby causing the problem of the damage of the rail top sealant. Patent document CN205329430U discloses a fastener cover having an adjustment plug, which transmits a load applied to the fastener cover by contact between the adjustment plug and a fastener spike bolt. However, the method causes the spike bolt to be subjected to additional impact, the impact is generated along with the passing of social vehicles, the magnitude of impact load and the generation time are irregular, and the spike bolt is easy to loosen under the stress state; in addition, the spike bolt is additionally impacted, so that the buckling force of the elastic strip is in an unstable state, the service life of a fastener system is easily shortened, and meanwhile, the adverse effect on the driving safety is generated.
In summary, the prior art cannot enable the fastener cover to not affect the normal performance of the fastening function of the fastener system under the condition of taking both elasticity and bearing capacity into consideration, and cannot meet the good long-term stability of the fastener cover and the pavement asphalt.
