Bridge tower and load-bearing cable connection point；Second anchorage is connect not less than bridge tower with load-bearing cable with load-bearing cable connection point
Point.
Further second anchorage and load-bearing cable connection point are higher than bridge tower and load-bearing cable connection point.
Projection of the minimum point of the load-bearing cable on girder is located at girder along bridge to center and second
Between anchorage.
The further girder high riverbank side lower end is provided with battered leg support；The battered leg support level pour in
The upper end of the steel box structure being vertically in tilted layout towards girder center on the massif of high riverbank side, battered leg support is supported on girder
Lower end surface.
Second anchorage and load-bearing cable connection point be higher than bridge tower and load-bearing cable connection point 10~
20m。
Further first anchorage and load-bearing cable connection point are not higher than the upper surface of girder.
The advantages of the utility model, has:
1, using unsymmetric structure, entire bridge is made only to can be achieved with bridge erection with a bridge tower, and reduces bridge
Tower height degree saves bridge tower project amount, greatly reduces project cost；
2, using unsymmetric structure, main push-towing rope specification is reduced, main push-towing rope steel wire quantity is reduced, better economy；
3, it is supported using battered leg, improves the structural stability that bridge main beam leans on high riverbank side；
4, structure economics, and because of the reduction of project amount, the duration reduces significantly compared to bridge types such as arch bridges；
5, a possibility that allowing mountain area to build suspension bridge is increasing, and adaptability is more and more stronger.
The bridge structure of the utility model is simple, and by asymmetrical bridge structure, it is difficult to solve the biggish riverbank of height difference
The problem of to arrange suspension bridge, reduces project cost and difficulty of construction, has great promotional value.

Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
Such as Fig. 1~2, a kind of asymmetric main push-towing rope railway Suspension bridge structure, including high riverbank and low riverbank are connected across river valley
Girder 1, the girder 1 of the present embodiment is Steel truss structure, and 1 one end of girder is connected with the tunnel of high riverbank side, the other end across
More river valley is connect with low riverbank.Inconsistent in order to adapt to two sides riverbank height difference, the present embodiment has poured bridge tower in low riverbank side
2, bridge tower 2 passes through girder 1 along the vertical direction.
Load-bearing cable 3 is provided on the bridge tower 2 of the present embodiment, load-bearing cable 3 is the combined load-bearing of multiply wirerope
Cable structure, load-bearing cable 3 are connect by more sunpenders 6 with girder 1, as shown in Fig. 2, girder 1 passes through load-bearing cable 2 and sunpender
6 across river valley.3 one end of load-bearing cable is fixedly connected with intracorporal first anchorage 4 in low riverbank side mountain is anchored at, and the other end passes through
2 upper end of bridge tower is fixedly connected with intracorporal second anchorage 5 in high riverbank side mountain is anchored at.
According to two sides riverbank structure, second anchorage 5 and 3 tie point of load-bearing cable of the present embodiment are higher than bridge tower 2 and load-bearing
3 tie point of cable can reduce the height of bridge tower 2 in this way, reduce cost.Wherein, the second anchorage 5 and 3 tie point of load-bearing cable
