It is as follows that the utility model solves the technical scheme that its technical problem used：
A kind of underground railway track construction of the present utility model, including armored concrete substrate, the middle part of armored concrete substrate
The ditch extended along circuit is provided with, it is characterized in that：Adjustment layer, adjustment layer and reinforcing bar are set on the armored concrete substrate
It is provided between cast concrete base in geotextiles separation layer, adjustment layer and lays track plates, the middle part of each track plates has center logical
Groove, central groove is located at the top in ditch.
The adjustment layer includes self-compacting concrete layer and polymer mortar layer, and polymer mortar layer is cast in reinforced concrete
Soil matrix bottom is located on the top surface of ditch both sides, and polymer mortar layer is cast under the bottom surface of self-compacting concrete layer.
Vibration reduction road mattress is equipped between the top surface of the armored concrete substrate and the bottom surface of adjustment layer.
The beneficial effects of the utility model are that orbit altitude can be reduced to 800mm, and adaptability is very strong, do not increase tunnel and break
Face, does not increase construction costs；Using open-type track plates, the heart sets Central drain in the substrate, and ditch cleaning maintenance is convenient, also not
Influence the durability of tunnel structure and track substrate；, can be convenient, fast by filled polymer screed after tunnel is settled
Reparation；When transforming demand if any vibration damping, can jacking track plate and adjustment layer link the composite construction to be formed, in the top surface of substrate
Laid between the bottom surface of adjustment layer after cushion blocking, you can form high damper rail system；Such as damping capacity is still not enough, may be used also
Increase balancing weight in track plates opening, increase track mass of vibration, further improve effectiveness in vibration suppression, transformation process is very simple
Singly, conveniently.
