Concrete sleeper and steel bar girder integrate an integral unit in advance in factory.
Prefabricated Concrete intermediate mass in above-mentioned technical proposal coordinates with concrete bed, realizes to the horizontal, vertical of cast-in-place railway roadbed
To constraint.The purpose for setting embedded sleeve barrel is, can be by after the taking-up of Prefabricated Concrete intermediate mass, using pre- when tunnel duct piece settle
Sleeve is buried as the tool interface for jacking cast-in-place railway roadbed.Because separation layer has separated cast-in-place railway roadbed and concrete bed,
The rail top mark height that cast-in-place railway roadbed recovers rail has been jacked, concrete mortar has been then injected into and fixes cast-in-place railway roadbed.Cast-in-place railway roadbed is
It is modular, leave plate stitch between each two unit, water supply and sewage and other cross the use of rail interface.
After two U-shaped steel tanks mix up track geometry in advance in factory, it is integrated into by concrete sleeper and steel bar girder
One integral unit, so as to effectively reduce on-site construction processes, shorten construction period, improve efficiency of construction.Rail also exists
Direct embedded is fixed in U-shaped steel tank in factory, reduces the cast process of polymer damping material at the scene.
In summary, by adopting the above-described technical solution, the beneficial effects of the utility model are：
1st, the design feature that embedded tracks continuously support is remained, effect of vibration and noise reduction is good；
2nd, when tunnel duct piece settles, prefabricated limited block is taken out, and cast-in-place railway roadbed is jacked, recovers the rail top mark of rail
Height, safeguard very convenient；
3rd, cast-in-place railway roadbed good integrity, beneficial to track structure stability；
4th, reduce the cast process of polymer damping material at the scene, shorten the site operation cycle, improve construction effect；
5th, left and right U-shaped steel tank is connected by steel bar girder in factory, forms the section of track, flash welding can be carried out between the section of track
Connect, the accurate gauge for ensureing left and right track, reduce rail system accurate adjustment number, shorten the site operation cycle.
Preferably, the outside of the U-shaped steel tank two welding U-shaped dowel.U-shaped dowel can further strengthen consolidating for U-shaped steel tank
It is set for using.
Preferably, the contact surface between the Prefabricated Concrete intermediate mass and cast-in-place railway roadbed is additionally provided with buffer plate.At some
There is the location of special vibration damping demand, level 2 buffering backing plate can also be set.
Preferably, the rail is fixedly installed in U-shaped steel tank by polymer damping material.
Preferably, the position at the top of the cast-in-place railway roadbed between two rails is recessed and set for attachment rail signal
Standby concave shaped space.
Preferably, sink to forming the peace for attachment rail power supply unit on the outside of two rails at the top of the cast-in-place railway roadbed
Fill space.
