The invention provides a kind of buried
track bed plate,
track bed and its construction method, because with multiple buried vibration isolators, plate body is arranged on the
basement by multiple rubber springs, adopts point support mode to
cut off the rigid connection between track structure and
basement structure, absorbs the
impact energy when
train runs, realizes vibration reduction and
noise reduction.The construction method of the invention combines the concept of prefabricated building, can improve construction accuracy and effect, the plate body uses prefabricated plate, the mounting seat of buried vibration
isolator is pre-buried below the plate body, during construction, only need to place the height adjusting
washer and spring
assembly containing rubber spring on the
basement at the set vibration
isolator position, then place the prefabricated plate on the basement, make the upper end of spring
assembly embedded in the corresponding mounting seat, the construction of buried
track bed plate can be completed, therefore, construction is convenient, short construction period, suitable for track construction on viaduct.
