Technical field
The utility model is related to a kind of ballastless track system；More particularly to a kind of high-speed railway trouble area's plate-type ballastless track
Use switching turnout plate.
Background technology
China Express Railway Cha Qu laying platy ballastless track structure has become developing direction, and switching turnout plate is pre- using batch production
System, scene laying operating efficiency is high, and with higher construction precision, Track regularity is good, while can guarantee that the high stable of track
Property and high reliability.
At present high-speed railway switch area ballastless track structure mainly has two kinds of patterns, a Shi Cha areas sleeper flush type, railway roadbed
Concrete takes cast in situs；Two Shi Cha areas are board-like, switching turnout plate prefabrication.Cast in situs sleeper flush type road road bed board is easily opened
Split, affect structure durability, and site operation is less efficient.Existing switching turnout plate structure is connected not tight enough with substructure interlayer
It is close, there is switching turnout plate and adjustment layer gap phenomenon during operation, while track switch plate surface is without precracking, over time, road
The crack that the trouble plate later stage produces is irregular, ftractures at track and happens occasionally, this stability and durability to switch structure
Generate adverse effect.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of switching turnout plate and is completely embedded with bottom adjustment interlayer,
Ensure switching turnout plate strong switching turnout plate of steadiness in circuit operation.
The technical scheme that the utility model is adopted is：A kind of ballastless track of high-speed railway switching turnout plate, carrying rails and
The switching turnout plate bottom anchor of fastener for installing has connection reinforcing bar；The top surface of the switching turnout plate is formed with the support rail for installing track switch fastener
Platform, to adjustment layer under switching turnout plate the grout hole of construction is irrigated；Drain groove is provided between track.
The switching turnout plate bottom reinforcement bars part is embedded in switching turnout plate bottom, and another part structure is under " door " shape and switching turnout plate
Portion's adjustment layer is coupled.
Drain groove bottom centre position is formed with " V " type precracking.
Fastening bolt installing hole is formed with the track.
The side of the switching turnout plate is embedded with lifting or mobile bolt and accurate adjustment bolt.
The track and plane-parallel.
The beneficial effects of the utility model are：Due to having connection reinforcing bar in switching turnout plate bottom anchor, connect the another of reinforcing bar
Part is coupled for " door " shape with switching turnout plate bottom adjustment layer, makes switching turnout plate plate bottom integral with adjustment layer shape, that is, ensure
Switching turnout plate is completely embedded with bottom adjustment interlayer, it is to avoid the problems such as gap occur between plate bottom and adjustment interlayer, it is ensured that track switch
Plate provides reliable infrastructure in circuit operating steadiness during for bullet train by trouble area.In addition, " V " type is pre-
Crack can avoid switching turnout plate from producing crack to the damage caused by track, improve the durability of switching turnout plate；It is prefabricated in switching turnout plate
After the completion of, in fastening bolt hole of accurately spudding in, turnout slab die species can be reduced, cost is reduced, while also improving track
Precision.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
As shown in Figure 1 to Figure 3, the utility model ballastless track of high-speed railway switching turnout plate is that strength grade of concrete is
C55, is prefabricated in the factory；There is connection reinforcing bar 9 in the bottom anchor of switching turnout plate 1 of carrying rails and fastener for installing；The steel of switching turnout plate bottom 6
The embedded switching turnout plate bottom of a muscle part, another part is coupled for " door " shape with switching turnout plate bottom adjustment layer, wherein, grout hole
Adjustment layer is irrigated construction under 4 pairs of plates, and in adjustment layer filling process, the connection reinforcing bar 9 at switching turnout plate plate bottom is formed with adjustment layer
One is overall, effectively switching turnout plate can be connected not closely with bottom adjustment interlayer, plate bottom and the problems such as adjust interlayer and gap occur, guarantor
The steadiness on the line of switching turnout plate is demonstrate,proved, during for bullet train by trouble area reliable infrastructure has been provided；The road
The top surface of trouble plate 1 is formed with track 2, grout hole 4 and drain groove 5；Track 2 and plane-parallel, form on track 2
There is fastening bolt installing hole 3 for installing track switch fastener, the installing hole treats drill precise holes after the completion of switching turnout plate production in factory
Form, it is ensured that the precision of hole position, reduce turnout slab die species, reduce cost；Grout hole 4 is again inspection hole to track switch
Adjustment layer is irrigated construction and checks under plate；Drain groove 5 is formed between two tracks 2, in the middle of the bottom of drain groove 5
Position is formed with " V " type precracking, if under special circumstances switching turnout plate generation crack can control its developing direction, it is to avoid to holding
Rail platform causes to damage, and improves the durability of switching turnout plate；The side of switching turnout plate 1 is embedded with lifting or mobile bolt 7 and accurate adjustment bolt
8, switching turnout plate is lifted by crane or moved when transporting by pre-buried bolt 7 in plate, and switching turnout plate is laid on the line in place rear logical
Cross accurate adjustment bolt 8 accurately to adjust switching turnout plate geometric position, to reach the high smooth degree requirement of high-speed railway, it should be pointed out that
It is that bolt hole carries out drilling formation after the completion of prefabricated, reduces mould species when switching turnout plate is produced, reduce cost, and carries
