End is fixed on the upside of the first bracket, and the other end connects base course, and the downside of the first attachment strap and base course is arranged in fill stratum, the
Two attachment straps are horizontally set in the fill stratum on the downside of the first attachment strap, and one end of the first attachment strap is fixed on the upside of the second bracket, and
The length of second attachment strap is greater than the length of the first attachment strap.
First attachment strap is equipped with a L-shaped stepped plate far from one end of abutment, and stepped plate and the first attachment strap are one
Body structure is equipped with multiple waterproof platforms protruded into base course in the upside of stepped plate.
Coal tar carpet veneer is equipped on the downside of the stepped plate.
The upside of first bracket is equipped with embedded bar, and the end of the first attachment strap offers reinforcing bar connecting hole, pre-buried
Reinforcing bar upper end is inserted into reinforcing bar connecting hole, has poured concrete in reinforcing bar connecting hole.
Length in the embedded bar insertion reinforcing bar connecting hole is the 40%~55% of the first attachment strap thickness.
The length that the embedded bar is inserted into the first bracket is 150~200mm.
Rubber interlayer is equipped between first attachment strap and the first bracket.
The downside of first attachment strap is equipped with a downward waterproof every platform, and the one of the first bracket is arranged in every platform in waterproof
Side.
The upside of first attachment strap and base course is equipped with bitumen layer.
The utility model has the advantages that the utility model can effectively prevent the heavy of fill stratum using the second attachment strap
Drop can reduce or even avoid the even if the fill stratum on the downside of the second attachment strap settles, but since the length of the second attachment strap is longer
Fill stratum sedimentation between one attachment strap and the second attachment strap, effectively prevent that there is a phenomenon where bumping at bridge-head generations.

Specific embodiment
The following examples illustrate the utility model, but is not intended to limit the scope of the present invention.
Embodiment 1
Referring to Fig. 1, which includes abutment 1, the first attachment strap 4, the second attachment strap 11, fill stratum 12 and base course 8, bridge
The rear side of platform 1 is equipped with the first bracket 2 and the second bracket 3, and the first bracket 2 is located at the top of the second bracket 3, and the one of the first attachment strap 4
End is fixed on the upside of the first bracket 2, and the other end connects base course 8, and the upside of the first attachment strap 4 and base course 8 is equipped with bitumen layer
9, the downside of the first attachment strap 4 and base course 8 is arranged in fill stratum 12, and the second attachment strap 11 is horizontally set on 4 downside of the first attachment strap
In fill stratum 12, one end of the first attachment strap 4 is fixed on the upside of the second bracket 3, and the length of the second attachment strap 11 is greater than first and takes
The length of plate 4.
The downside of first attachment strap 4 is equipped with a downward waterproof every platform 10, and the one of the first bracket 2 is arranged in every platform 10 in waterproof
Side, waterproof can prevent the first attachment strap 4 and the water of 1 junction of abutment from penetrating down into fill stratum 12 every platform 10, and it is heavy to avoid occurring
Drop.
First attachment strap 4 is equipped with a L-shaped stepped plate 5 far from one end of abutment 1, and stepped plate 5 is integrated with the first attachment strap 4
