Abstract
The invention discloses a monolithic rail bed and turnout lifting support arrangement structure of a subway short sleeper. The monolithic rail bed and turnout lifting support arrangement structure comprises point rails (1), frogs (2), guard rails (3) and rails (4). Specific rail lifting supports (5) are arranged below steel rails in overlapped sections of the point rails (1) and the rails (4), below the frogs (2) and below steel rails in overlapped sections of the guard rails (3) and the rails (4). Heightened rail lifting supports (6) are arranged below steel rails in joint sections of every two rails (4) between the point rails (1) and the frogs (2). Main-line track lifting supports (7) are arranged below steel rails of the rails (4) outside of the point rails (1) and the frogs (2). The monolithic rail bed and turnout lifting support arrangement structure has the advantages that three types of track lifting supports are designed to lift up the integrated rail bed, concrete buttresses in a buttress method are replaced, height can be adjusted optionally, elevation height of turnout rail tops can be well controlled, constructing quality for turnout pouring is improved, construction period of the turnout is shortened by 30-50%, and meanwhile the rail lifting supports are easy to dismantle and can be repeatedly used, so that construction cost is greatly saved.
Description
Technical field
The present invention relates to a kind of support configuration structure that solid concrete roabed track switch is held up.
Background technology
The construction of metro short sleeper solid concrete roabed track switch, to adopt the construction of buttress method to live method commonly used, it is first on-site consolidation track switch, connect short sleeper and button accessory, with track jack jack-up track switch connector, by the mode of " watering 1 every 2 " the buttress template is installed and pours into a mould first the buttress concrete, after the buttress concrete strength reaches design strength 75%, remove the buttress template, take to carry out in the mode of a buttress bottom pad elevation accurate adjustment of whole track switch, pour into a mould again the Turnout Monolithic Track Bed concrete after the track switch physical dimension is up to standard.The method needs the secondary concreting, not only duty cycle long, increase construction cost, the buttress Construction Elevation is difficult to control, be prone to buttress and pour into a mould the afterwards high superelevation of turnout rail top mark or not foot phenomenon, also have the quality disease of the short sleeper of buttress place part " sky hangs " simultaneously.It is about 12～14 days that 1 group of P60kg/m singly opens traditional " buttress method " the construction technology construction period of short sleeper solid concrete roabed track switch employing for No. 9, and the construction period of double crossover is then longer.
In traditional " buttress method " construction technology of metro short sleeper solid concrete roabed track switch, the turnout baseplate place generally adopts the sleeper bottom pour mold to build concrete buttress to carry out leveling, on-the-spot construction adjustment difficulty is larger, quality is wayward, often cause the short sleeper planeness at turnout baseplate place inadequate, cause indivedual slide plates place to hang the sky unbalance stress or cause frictional resistance too large because of out-of-flatness.
Summary of the invention
The technical problem to be solved in the present invention: buttress height problem wayward and long in time limit when adopting the construction of buttress method in the metro short sleeper solid concrete roabed track switch construction provides a kind of track lifting support configuration structure with the whole picking-up of track switch.
Technical scheme:
A kind of metro short sleeper solid concrete roabed track lifting of turnout junction rack arrangement structure, comprise tongue, railway frog, guard rail and track, below the rail of the tongue of track switch and Orbital Overlap section, below the railway frog, below the rail of guard rail and Orbital Overlap section special track lifting support is set, the rail of the section of crossing of two strands of tracks below arranges and increases the track lifting support between tongue and the railway frog, and the rail of track below arranges main track track lifting support outside tongue and the railway frog.
The track lining screw mandrel is set between the metope of track and subway tunnel, and the track lining screw mandrel is comprised of transverse screw and sleeve, and transverse screw is installed in the nut of sleeve one end connection.
Track in the tongue outside is set up the slide plate suspender, and two suspension rod screw mandrels are installed in the overarm of slide plate suspender, and suspension rod screw mandrel upper end is equipped with nut, and the lower end connects with side's pad of being connected.
The both sides of the supporting plate in the middle of the special track lifting support are equipped with nut, and vertical screw rod is installed in the nut, and there is a horizontal through hole vertical screw rod upper end.
Increasing the track lifting support has two support rail plates, and two support rail plate installed inside are increased part, increases between the part for two to connect with connector, and the support rail plate outside is equipped with nut, and vertical screw rod is installed in the nut, and there is a horizontal through hole vertical screw rod upper end.
Main track track lifting support has two support rail plates, connects with connector between two support rail plates, and the support rail plate outside is equipped with nut, and vertical screw rod is installed in the nut, and there is a horizontal through hole vertical screw rod upper end.
Beneficial effect:
1. having designed three kinds of track lifting supports holds up whole railway roadbed, replaced the concrete buttress in the buttress method, but height free adjustment, it is high to control the turnout rail top mark, improved the track switch cast construction quality, accelerated the construction period of track switch, can shorten 30～50% construction period, the support that raises track simultaneously is easy to dismounting and can reuses, and has greatly saved construction cost;
2. rail arranged outside track lining screw mandrel on railway roadbed, horizontal level that can accurate adjustment track switch improves workmanship;
3. according to the characteristics of turnout baseplate structure: slide plate one side is withheld by elastic bar fastener and is fixed slide plate and rail, and opposite side does not have then that fastener is fixing easily to cause the slide plate out-of-flatness.For this characteristics, designed a kind of suspender and fastener jointly the power of holding come the leveling slide plate.Suspension rod nut that simultaneously can elevating sling comes the leveling slide plate, and the scene is easy to control and operation, and suspender also can be dismantled use repeatedly.
