Specific embodiment

Below in conjunction with the accompanying drawings and embodiment is described in further detail to the technical solution of the utility model.

Embodiment one, as shown in figure 1, a kind of ultra low type viaduct, including lower floor's rotary island 5, major trunk roads 1, subsidiary road 9 and and Upper strata rotary island 11, lower floor's rotary island 5 is located at the intersection of major trunk roads 1 and subsidiary road 9, and two frame trunk bridges are provided with major trunk roads 1 Beam 4, and two frame major trunk roads bridges 4 respectively be located at the two ends of lower floor's rotary island 5, two frame major trunk roads bridges 4 respectively with the trunk of respective side Road is connected by first slope 3, and the pillar that upper strata rotary island 11 is located at the top of lower floor's rotary island 5 and is set by its underpart is supported, on Layer rotary island 11 is connected by the second slope respectively with the two framves major trunk roads bridge 4, and second slope is by upper insular slope 7 Constituted with lower insular slope 8, two frame major trunk roads bridges 4 are respectively by bridge slope 6 once and the major trunk roads portion being located in lower floor's rotary island The two ends divided are connected, and are located between the upper insular slope of respective side and lower insular slope per bridge slope 6 once；5 liang of lower floor's rotary island The subsidiary road 9 of side is connected between upper strata rotary island 11 by the 3rd slope 10 respectively.

Lower floor's rotary island 5 is ellipse, and two major trunk roads bridges 4 are located at corresponding on lower floor's rotary island 5 two most respectively Distal end.

The major trunk roads 1 and subsidiary road 9 are two-way lane.

The first slope 3, the slope 10 of Xia Qiao slopes 6 and the 3rd it is domatic on be equipped with two-way lane.

The major trunk roads 1 and the both sides of subsidiary road 9 are respectively arranged with bicycle lane.

The bottom surface of major trunk roads bridge 4 is at least 2m away from the road surface clear height of lower floor's rotary island 5.

The bottom surface of upper strata rotary island 11 is at least 3.5m away from the road surface clear height of major trunk roads 1 in lower floor's rotary island.

Lower floor's rotary island can set two kinds of structures：

A kind of structure is：Lower floor's rotary island rest on the ground, and lower floor's rotary island and its internal major trunk roads part and ground position In same plane.

Another structure is：Lower floor's rotary island is that the sink structures for being formed are dug by subsurface, specifically, lower floor's rotary island 5 and its inside major trunk roads part can by subsurface dig 0~4 meter is formed, when lower floor's rotary island and/or its inside major trunk roads part During lower digging, the height of major trunk roads bridge 4 and/or upper strata rotary island 11 accordingly declines, relative the purpose is to be used to reducing upper strata rotary island Total height reduction when viaduct highly, after being easy to is built in the construction on ground, and the reduction of major trunk roads bridge height so that first The length on slope and the 3rd slope shortens.

There is method during crossroad of the present utility model to illustrate by building on vehicle, it is as follows：

If the 1, motor vehicle is travelled and during by viaduct of the present utility model in major trunk roads, motor vehicle is by side first To on major trunk roads bridge in first slope；

1）If motor vehicle is kept straight on, driven to by Xia Qiao slopes on the major trunk roads part in lower floor's rotary island, then from another The trunk of the first slope arrival opposite side that the Xia Qiao slopes of side drive on the major trunk roads bridge of opposite side and pass through opposite side Road, completes straight trip process.

2）If motor vehicle is turned right or turned left, driven on the rotary island of upper strata by the second slope, then from upper strata rotary island both sides The 3rd slope drive on the subsidiary road of corresponding side, complete turn right or turn left.

3）If motor vehicle if desired turns around on major trunk roads, upper strata rotary island is driven to through first slope, upper bridge slope, so After detour upper strata rotary island after one week from Xia Qiao slopes drive to first slope finally drive on major trunk roads complete turn around.

If, motor vehicle travelled in subsidiary road and during by viaduct of the present utility model, motor vehicle is by the 3rd slope Onto upper strata rotary island, and detoured on the rotary island of upper strata；If motor vehicle is turned right or is turned left, from the second slope of upper strata rotary island both sides Drive on major trunk roads bridge, then driven on major trunk roads by first slope again, if motor vehicle is kept straight on, from upper strata rotary island 3rd slope of offside is driven on subsidiary road, completes to pass through.

3rd, on major trunk roads when non-motor vehicle and pedestrian passes through viaduct of the present utility model,

1）During to straight trip or right-hand rotation, then completed by the lower floor's rotary island that detours.

2）To turn left, then detour and lower floor's rotary island and continue the lower floor's ring that detours after being passed through under opposite side major trunk roads bridge Island, completes.

4th, on subsidiary road when non-motor vehicle and pedestrian passes through viaduct of the present utility model,

1）To straight trip, then detour lower floor's rotary island and passes through under major trunk roads bridge, continues the lower floor's rotary island that detours, and reaches another Side subsidiary road, completes straight trip.

2）To turn left, then detour lower floor's rotary island and passes through under major trunk roads bridge, continues the lower floor's rotary island that detours, and reaches another On the major trunk roads of side, straight trip is completed.

3）To turn right, then directly detour lower floor's rotary island, you can completes.

It is completely separable with non-motor vehicle, pedestrian that the utility model fully achieves motor vehicle, substantially increases road Safety, and without setting traffic lights, traffic efficiency is improve, save the time.
