Description

A kind of board-like track structure of framework in tunnel
Technical field
The utility model is related to technical field of rail traffic, particularly a kind of framework slab track knot in tunnel Structure.
Background technology
In traditional track traffic, rail is fixed together by fastener with track or sleeper, be positioned over the tiny fragments of stone, coal, etc. or On ballastless track bed.The process of its whole work progress is more, long construction period, can largely effect on the unimpeded and city of urban road The trip of the people;It is guarantee driving safety, it is necessary to which often contacting piece is checked simultaneously and fastener easily loosens in use Again tighten, maintenance workload is big, high cost.
Gradually highlighted for the mode of transportation of this large conveying quantity of subway, the problems such as rail wear, vibration noise, conventional rails The maintenance workload of structure is larger, and higher requirement is proposed to operation management;And in urban track traffic, subway Most sections are all located underground, and the rail of conventional rails system is all higher than the sleeper or Prefabricated integral non-fragment orbit of bottom Plate, this structure is disadvantageous in that wheeled vehicle travels very inconvenient in tunnel, particularly occurs accident in tunnel When, will have a strong impact on common fire-fighting, breakdown lorry enter tunnel in implement fire-fighting and rescue.
In current disclosed embedded tracks, integral rail plate is realized and bottom coagulation by self-compacting concrete The connection of native base, this connected mode does not adapt to foundation settlement in tunnel, and is unfavorable for maintenance.In addition, monoblock type The limited impression of track plates bottom is also unfavorable for the processing and manufacturing of track plates.

Preferably, adjustment supporting layer is set between the Prefabricated integral fragment-free track slab and concrete bed, and Adjust supporting layer outer application closing waterproof layer.
Preferably, one layer of abatvoix is set on the Prefabricated integral non-fragment orbit plate top surface, and by each prefabricated entirety Plate stitch covering between formula fragment-free track slab.Abatvoix can substantially reduce the noise radiation of Prefabricated integral fragment-free track slab, subtract Overhead and influence of noise of the above-ground route to surrounding environment is particularly around baby track circuit.
Preferably, the concrete bed bottom is fixedly connected with the tunnel duct piece of circular arc, and by presetting shearing resistance Cut reinforcing bar to connection strengthen, and junction and tunnel duct piece surface coating waterproof layer, the concrete bed both sides with Gutter is formed between tunnel duct piece, so as to effectively strengthen rail system drainability.
Preferably, setting resilient sleeper-bearing under rail, height adjusting cushion plate and rail under rail in the rail support groove from bottom to top, hold Its complementary space filled high polymer damping material in track slot.Further preferably, the support rail groove bottom towards Prefabricated integral without the tiny fragments of stone, coal, etc. Track plates transverse direction middle part is downward-sloping, or, rail cant backing plate is set under the rail and rail between height adjusting cushion plate.Support rail Groove bottom tilts the effect equivalent to rail cant, and the setting of rail cant can be effectively improved the contact relation of rail and car wheel-set, Reduce rail abnormal wear.
Preferably, the rail both sides set some tune rail assemblies respectively, the tune rail assembly includes retainer and wedge Shape block, the retainer side is fitted with steel rail web surface, and opposite side is inclined-plane, the wedge side and retainer it is oblique Face is fitted, and opposite side is fitted with support rail groove sidewall.
Preferably, the rail both sides set some noise reduction blocks, the noise reduction block one side and steel rail web table respectively Fit in face.Noise reduction block can reduce the vibration noise of rail system, and reduce the workload of cast-in-site macromolecule material.
In summary, by adopting the above-described technical solution, the beneficial effects of the utility model are:
1st, rail is embedded into below track plate surface, so as to overcome the surface of current conventional rails structure presence just Uneven the problem of, fire-fighting, breakdown lorry is facilitated to pass through.
2nd, by setting cavity in track plate, frame plate structure is formed, track plates deadweight can be effectively reduced, be easy to Construction and later maintenance.
3rd, coordinated using the semi-circular recesses and cylinder gear platform at Prefabricated integral fragment-free track slab two ends, realized to pre- The elastic spacing of integral ballastless track plate vertical and horizontal processed.
The 4th, adjustment supporting layer is set between Prefabricated integral fragment-free track slab and concrete bed, Prefabricated integral is realized The continuous elastic support of fragment-free track slab, effectively adapts to the foundation settlement in tunnel, changes the maintenance of embedded tracks system It is more convenient.
The 5th, shear reinforcement, the concatenation ability of enhancing tunnel duct piece and rail system base are set in advance on tunnel duct piece.
6th, shorten construction period, weaken rail wear and vibration noise.
