In above scheme, the roadbed boxed frame further includes tubular pole, and the tubular pole is located at below the bottom plate, described
Tubular pole extends downward preset length from the bottom plate.
In above scheme, the tubular pole is fixed to the bottom plate by raft plate.
In above scheme, the quantity of the side wall panel is two, and the height of the side wall panel is greater than the cross of two side wall panels
To spacing.
In above scheme, the roadbed is poured with boxed frame use ≮ C35 armored concrete.
In above scheme, the transverse width of the side wall panel is 0.4~0.6 meter, the cross of two adjacent side wall panels
It is 4.6~6.5 meters to spacing.
In above scheme, the top plate with a thickness of 0.4~0.6 meter, the top plate extends in the outside of the side wall panel
3.0~3.7 meters；The bottom plate with a thickness of 0.8~1.2 meter, the bottom plate extends 0.9~1.1 in the outside of the side wall panel
Rice.
The embodiment of the invention also provides a kind of box frame roadbed, the box frame roadbed includes that the roadbed of preset quantity is used
Boxed frame is longitudinally forming, the adjacent roadbed expansion joint that preset length is separated between boxed frame；The road
Base boxed frame is any one roadbed boxed frame recited above, and the side wall panel of the roadbed boxed frame is distinguished
Positioned at the centre of two rail on two lines road.
In above scheme, the raft plate is located at the centre of two adjacent roadbed boxed frames, and the raft plate is in longitudinal direction
One end connect a roadbed boxed frame, the other end and be connected to another roadbed boxed frame.
In above scheme, each roadbed is provided with tubular pole, two adjacent roads with the both ends of boxed frame bottom
Tubular pole under base boxed frame is symmetrical with the expansion joint between two roadbed boxed frames, and is fixed on the same raft
On plate.
The roadbed boxed frame and box frame roadbed of the embodiment of the present invention, the roadbed boxed frame include top plate,
Bottom plate and at least two side wall panels between the top plate and bottom plate, upper end, the lower end of the side wall panel are separately connected described
Top plate and the bottom plate；At least two side wall panels the top plate or bottom plate cross direction profiles, and described in adjacent two
