Embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
A kind of ballast bed structure that limit location is invaded suitable for shield tunnel, if including the pedestal 1 that sets gradually from the bottom to top and
Dry sleeper 2, pedestal 1 are fixed on section of jurisdiction 100, and sleeper 2 is fixed on pedestal 2.Preferably, in order that the connection of pedestal 1 and sleeper 2 is steady
Gu reliable, the bottom of sleeper 2 is in pedestal 1.Specifically, when pouring into a mould pedestal 1, the bottom of sleeper 2 is embedded in pedestal 1
It is interior.Compared with prior art, sleeper 2 is directly arranged in pedestal 1, and road passes structure equivalent to the height for reducing a track plates, full
Foot invades the height design requirement in limit location.
Preferably, in order to further pedestal 1 and sleeper 2 are firmly connected as one, it is preferable that in pedestal 1 and rail
Some second reinforcing bars 21 are provided between pillow 2, one end of the second reinforcing bar 21 is in pedestal 1, and the other end is in sleeper 2.In order to
The whole height of ballast bed structure is further reduced, the height that sleeper 2 of the present utility model designs is 130mm.
Preferably, pedestal 1 is provided with gutter 12.In order to meet to invade the height design requirement in limit location, the height of pedestal 1 compared with
Low, therefore, the width of the upper surface of pedestal 1 is smaller, it has not been convenient to gutter 12 is set in the both sides of pedestal, it is therefore preferred that will
Gutter 12 is located at the middle part of pedestal 1, meanwhile, done as far as possible greatly, to increase drainage efficiency in the case where ensureing the intensity requirement of pedestal 1.
Because the height of pedestal 1 is relatively low, the intensity of pedestal 1 can be impacted, and therefore, the utility model uses C50 concreting base
Seat 1, to improve the intensity of pedestal 1.
