The specific embodiment:

Technical solutions of the utility model are that the crossroad that a kind of three bridges combination realizes full intercommunication is reconstructed in the crossroad of existing traffic lights management and control.

The crossroad that this three bridges combination realizes full intercommunication, as shown in Figure 1.Among Fig. 11 is exactly in the middle of the road of an at the parting of the ways direction, a special-purpose viaduct of the through vehicles across another direction road of building.The shape of the special-purpose viaduct of through vehicles as shown in Figure 2, width is half (also can increase and decrease to some extent according to actual needs) of road, bridge bottom clear height at the parting of the ways is 4.5 meters, and the gradient that viaduct is connected with original road is 2.5%, also can reduce according to actual needs the gradient.Advantage is not only to be conducive to driving, can also at the bottom of the viaduct as the parking lot, shortcoming is to increase cost, in the situation that can't increase the parking lot, or a good selection.Among Fig. 12 is exactly on the road of at the parting of the ways another direction, two through vehicles service bridges building in the both sides of the special-purpose viaduct of through vehicles.The shape of through vehicles service bridge as shown in Figure 3, width is half (also can increase and decrease to some extent according to actual needs) of road, the bridge bottom clear height of service bridge is 2 meters (also can increase according to actual needs height), length equates with the width of road, the gradient that service bridge is connected with original road is 2.5%, also can with service bridge be connected viaduct and directly connect, not only can increase the parking space, also help ease driving.

The crossroad that the combination of three bridges realizes full intercommunication needs in flakes combination, could effectively bring into play usefulness.As shown in Figure 4, its combination is that described crossroad has several, the road of the special-purpose viaduct of the through vehicles that each crossroad is built is connected with the road of the through vehicles service bridge that next crossroad is built, and road all around all connects by this feature.That is to say that every road of building viaduct must be connected with the road of building service bridge, every road of building service bridge must be connected with the road of building viaduct.If fund allows, also the special-purpose viaduct of through vehicles can be connected with the through vehicles service bridge, the parking space under the viaduct will increase much, and the problem of urban road parking difficulty also will be eased.The crossroad that the combination of three bridges realizes full intercommunication not only can be made up in flakes, also can use separately.When using separately two through vehicles service bridges are all reconstructed into the special-purpose viaduct of through vehicles, all left-hand bend vehicles all pass through under the special-purpose viaduct of the through vehicles after the reconstruction, realize simultaneously full intercommunication.

The crossroad that the combination of three bridges realizes full intercommunication, the mode of its full intercommunication is: as shown in Figure 5, the track set-up mode of original left-hand rotation-craspedodrome-right-hand rotation is changed over the track set-up mode of craspedodrome-turning.Although (the change that the track arranges, the custom of travelling on the driver can affect to some extent, as long as but the driver has distinguished and keeps straight on and turned, moreover is exactly to have gone to the wrong way to turn around at the special-purpose viaduct of through vehicles and through vehicles service bridge, can not cause and block up because walking lay-by.) turning roadway is divided into again left turn lane and right-turn lane, the right-hand bend vehicle is current in original right-turn lane, the transit route shown in Fig. 5 dotted line.The dilly left-wheel be and the parallel turning roadway of the special-purpose viaduct of through vehicles, have at the parting of the ways and forbid the sign of keeping straight on, then turn right first and advance to the through vehicles service bridge, pass through vehicles service bridge left-hand bend craspedodrome and import gradually direct lane, reach the left-hand bend purpose; The dilly left-wheel be the bend that will pass the special-purpose viaduct of through vehicles, keep straight on after then passing a bridge, pass under the through vehicles service bridge, turning right enters turning roadway, then import direct lane and finish left-hand bend, the transit route shown in Fig. 5 chain-dotted line; Oversize vehicle turns left and only will walk stretch more, passes under the through vehicles special use viaduct of next crossroad to get final product.(when the combination of three bridges realizes that the crossroad of full intercommunication is used separately, because two through vehicles service bridges are all reconstructed into the special-purpose viaduct of through vehicles, all left-hand bend vehicles all under the special-purpose viaduct of through vehicles by) through vehicles is current at special-purpose viaduct and service bridge, the transit route shown in Fig. 5 solid line.Bicycle and pedestrian pass through the transit route shown in Fig. 6 dotted line under the bridge of the special-purpose viaduct of through vehicles and through vehicles service bridge.

In sum, the utility model technology is simple and practical, is applicable to the transformation of city road crossing.This technology not only improvement cost is low, and the construction period is short, without whole enclosed construction, on underground pipeline change move the impact little, can also greatly reduce the negative effect that the reconstruction process causes.The not only energy-conserving and environment-protective of the utility model technology have also increased half path resource, have improved the unit interval vehicle flowrate, can effectively crack the difficult problem of urban road traffic congestion.
