The technical solution adopted in the utility model is such:
A kind of embedded tracks system, comprise basis, precast track plate and rail, on described precast track plate, the width parallel of corresponding Railway wheelset offers two acclive rail support grooves in bottom; In rail support groove, first continuous laying resilient sleeper-bearing, the more discrete bottom that arranges also has the height adjusting cushion plate of the gradient same with bottom rail support groove, then in groove, arranges rail; At rail two side bonds prefabricated section, and wedge is set between prefabricated section and support rail cell wall to adjust rail lateral attitude; In rail support groove, pour into a mould Macromolecular pouring material fill up remaining space; Form adjustment layer by cast-in-situ concrete precast track plate and basis are combined.
In the technical program, arrange bottom described rail support groove bottom the gradient and adjustment backing plate and the same gradient is also set, thus can by the action of resilient sleeper-bearing movement in rail support groove being adjusted easily the height of rail.Described prefabricated section coordinates with wedge, adjustable the position of interim constraint rail, to be detected qualified after, then pour into a mould Macromolecular pouring material, thus realize final fixing.Described Macromolecular pouring material can say that all parts in rail support groove is bonded as one, operative constraint the rail that locks, and meanwhile, reduces vibration and the noise of track.
As preferably, described resilient sleeper-bearing adopts polyurethane foam backing plate to make, and length, between 1 meter-1.5 meters, is preferably 1 meter or 1.5 meters.Described resilient sleeper-bearing continuous laying below rail, effectively can reduce the abnormal wear of wheel track.This point is different from conventional rails, and the backing plate of conventional rails plays the effect of supporting, and is be interrupted to lay.And resilient sleeper-bearing in this programme is bonding with the bottom land of rail support groove by bonding agent, thus fixing.
As preferably, on described basis, corresponding every block precast track plate is provided with two place's pits, is correspondingly embedded in pit by pouring into a mould the embedded post block in formation two place bottom described adjustment layer.
As preferably, the separation layer that one deck insulation materials supports is set between adjustment layer and basis.Separation layer be used for being separated between adjustment layer with basis, be convenient to safeguard and insolated layer materials is high insulating property material, can effectively prevent stray electrical current to the corrosion of surrounding buildings.
As preferably, described Macromolecular pouring material height is different in rail both sides, and wherein the height of inner side is lower than the height in outside, is convenient to take turns passing through wheel rim.
As preferably, described prefabricated section side and rail side view are coincide, and opposite side is upwards shrink gradually domatic, and described wedge and this domatic one side contacted are also corresponding is set to the domatic of retracted downward gradually.
As preferably, between each described precast track plate, be provided with preformed plate seam.
As preferably, groove is offered as greening groove in the position of described precast track plate between two rail support grooves, and greening groove can be used for kind of a grass.
The utility model can meet the needs of existing urban track traffic, specifically, possesses following advantage compared with existing embedded tracks:
1, track circuit construction period is shorter: prefabricated section reduces the workload of cast-in-site, effective lifting construction speed, after track circuit has checked, namely pourable, decreases the restriction of environment to construction;
2, construction quality more easily ensures: precast track plate precision is high, can effectively ensure circuit geometric accuracy; Reduce the impact of environment on construction simultaneously;
3, be convenient to safeguard, change: have preformed plate to stitch between track plates, constructability and maintenance;
4, track structure dynamic performance is more excellent: by designing shape, the rigidity of prefabricated section, can promote the dynamic performance of track further, reduces vibration and noise.
5, track circuit longer service life: the macromolecular material parcel rail adopting high insulating property, and insolated layer materials good insulation preformance, effectively prevent stray electrical current to the corrosion of Adjacent Buildings; Embedded tracks structure effectively can reduce the vibration of track and vehicle, advancing the track circuit application life.
