It is applied, such as Chengdu Xinjin R1 line tramcars project, 2 line tramcar project of Chengdu Rong, Guangzhou Underground project.It is expected that
With the rapid development of urban track traffic, embedded tracks will at home as a kind of superior rail system of performance
It can all be used widely in iron, tramcar even high ferro.
In use, the later stage inherently generates line upkeep situation.The line upkeep difficulty of traditional embedded tracks
It is higher, it is a bottleneck engineering.For such issues that, also occur the structure optimization scheme of some maintenance class in industry, but tie
Fruit is all undesirable.
Therefore, when designing embedded tracks structure, should as far as possible be given convenient for taking into account the problem of constructing and safeguard
Construction is brought convenience with later maintenance.
Utility model content
The goal of the invention of the utility model is：In view of the above problems, provide a kind of convenient for construction and maintenance
Novel embedded continuous supporting ballastless track structure.
The technical solution adopted in the utility model is such：
A kind of novel embedded continuous supporting ballastless track structure convenient for construction and maintenance, including precast track plate, steel
Rail longitudinally opens up two rail support grooves for embedded setting rail on the precast track plate, and precast track plate both ends eliminate
After rail support groove continuous rail support groove is formed with rail support groove prefabricated component and the assembled fixation of precast track plate again；In rail support groove, between waiting
Every setting several reserved grooves, the pinch plate rail fastening to lock to rail is installed in reserved groove；The nothing in rail support groove
Remaining position of reserved groove, pouring foaming concrete is consolidated after two side bonds elasticity noise reduction block of steel rail web and in slot
It is fixed.
When rail support groove prefabricated component is not installed, the space of welding can be provided for rail, assembled fixed mode is convenient for the later stage
It safeguards.For elastic noise reduction block with foamed concrete in addition to providing certain rail transverse direction locking force, it is right during railroad embankment also to facilitate
Slot inner part carries out maintenance and cleaning.Locked using pinch plate rail fastening to rail, not only increase the security and stability of rail,
And rail can be fixed temporarily in track construction, as the walking rail of welding equipment and the fortune for track goods and materials
It is defeated, vehicle low speed safety can be also met between circuit maintenance phase.
Preferably, one layer of surface layer polymer damping material is also poured into a mould in rail support groove, by pinch plate rail fastening, elastic noise reduction block
It is sealed with foamed concrete, the protections such as waterproof, moisture-proof, antiultraviolet and uniform appearance can be carried out to each component in slot, carried
Rise the overall aesthetics of structure.
Preferably, between the rail foot and support rail groove bottom, the flexible backing plate of continuous laying and height adjusting cushion plate are simultaneously
Cast bottom polymer damping material fills gap to ensure that rail is continuously supported.
Preferably, sponge strip is placed in the rail foot both sides.Since sponge strip is flexible, convenient for tune during later maintenance
Whole gauge.
Preferably, brushing waterproof layer between the rail support groove prefabricated component and precast track plate.
The rail support groove prefabricated component realizes the connection between precast track plate by bolt.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are：
1st, welding space is reserved in precast track plate end, solves the problems, such as traditional embedded tracks welding difficulty；
2nd, pinch plate rail fastening system is introduced, can be locked in time after rail accurate adjustment, improves site operation efficiency；
3rd, during railroad embankment system maintenance, be fixed temporarily rail using pinch plate rail fastening, meet vehicle low speed peace
The requirement of all-pass row, does not influence railroad embankment；
4th, steel rail web both sides are using elastic noise reduction block and foamed concrete filling, and convenient for being safeguarded during railroad embankment when is clear
Manage slot inner part；
5th, it is mostly precast construction in slot, reduces high molecular material dosage, reduce cast-in-site amount.
