Specific embodiment
Following examples are used to illustrate the present invention, but are not limited to the scope of the present invention.
As shown in Figure 1 to Figure 2, the structure of main bridge of the bridge with air partition of the present invention is seven oblique across symmetrical hybrid beam
Draw bridge, be concrete box girder near end bay and main span Sarasota, in across it is most of be steel box-girder, using close Sarasota beam pier induration
System, arranges bi-directional movable bearing at auxiliary pier；Longitudinal sliding motion, horizontal hold-down support are adopted in transition pier and abutment；The bridge
Be designed with the bridge floor of beam left maintaining roadway railing 11, right maintaining roadway railing 12, left suspension cable 13, right suspension cable 14, left side prevent
Push away guardrail 17, right wing side to prevent pushing away in guardrail 18, left tapping pipe 19, right tapping pipe 20, left central median anticollision barrier 21 and the right side
Central median anticollision barrier 22, described left central median anticollision barrier 21 and right median dividing strip anticollision barrier 22 is arranged on
The position of the centre of the bridge floor of the steel box-girder, left central median anticollision barrier 21 and right median dividing strip anticollision barrier 22 it
Between be provided with pouring asphalt concrete, left maintaining roadway railing 11 is arranged on the left side edge of the bridge floor of the steel box-girder, right inspection
Railing 12 of cultivating oneself according to a religious doctrine is arranged on the right side edge of the bridge floor of the steel box-girder, and left side prevents that pushing away guardrail 17 is arranged on left maintaining roadway railing
Between 11 and left central median anticollision barrier 21, right wing side is anti-to push away guardrail 18 and is arranged on right maintaining roadway railing 12 and prevent with right wing side
Push away between guardrail 18, left side is anti-push away guardrail 17 it is anti-less than left side with the distance between left maintaining roadway railing 11 push away guardrail 17 with
The distance between left central median anticollision barrier 21, right wing side is anti-, and to push away guardrail 18 little with the distance between right maintaining roadway railing 12
Prevent pushing away the distance between guardrail 18 and right median dividing strip anticollision barrier 22 in right wing side, left side prevents that the side for pushing away guardrail 17 sets
Left tapping pipe 19 is equipped with, right wing side prevents that the side for pushing away guardrail 18 is provided with right tapping pipe 20；Left maintaining roadway railing 11 and right maintenance
Road railing 12 merges setting with air partition.
Left maintaining roadway railing 11 and right maintaining roadway railing 12 are used to guarantee the safety of bridge maintainer.
Described anticollision barrier adopts beams of metal post fence, and anti-collision level is SA levels.Fence upright is welded using steel plate
Molding, a height of 1500mm, basic spacing 1500mm, crossbeam specification is 1500 × 100 × 6mm, and full-length is 5980mm, is arranged
Four.Anticollision barrier column, crossbeam, column bottom adopt Q345C steel, should meet GB/T 1591-2008.
Anticollision barrier should meet the flexible of main bridge and rotate displacement at the expansion joint of bridge, and between the column of two ends crossbeam is contacted
Upper setting slotted hole meets the flexible requirement of girder, and contact crossbeam two ends are supported on reinforcing bar cylinder (being welded in outer cross rail inner) and meet
Rotating requires.
During laying on floorings protective coating agent and binding agent, it is ensured that pave-load layer and floorings secure bond, in wheel
Not rubbing under effect, not agglomeration.Bituminous concrete should not turn over oil under 60 celsius temperatures, not soften；It is Celsius subzero 15
It is not crisp strong when spending.When maintaining roadway is mated formation, should on maintenance guidance tape protective coating agent and binding agent, it is ensured that pave-load layer and floorings jail
It is solidly connected.
Girder two ends are equipped with expansion joint.Due to main bridge it is different from access bridge width, expansion joint direction across bridge should from into kerb,
In order to avoid rainwater is laterally revealed, affect attractive in appearance.
