The utility model discloses a core is two U -shaped cross -line overpasss (3) that (1) two orientation craspedodrome lane of yan zhuqiao was built, they have undertaken the task of traveling of turning left of (1) two craspedodrome direction vehicle on the main bridge, simultaneously owing to they follow the craspedodrome lane outside to erect, go up a slope, the access bridge of downhill path has only occupy two the lane area soils in craspedodrome lane both sides, the tune of turning occupies is the upper portion space in lane of going straight, additionally do not occupy the soil, thereby the effectual soil that has utilized, inferior bridge (2) are that the plane is current completely, additionally do not occupy the soil, capacity has improved more than the twice.

Description

Half range diesis shape interchange overpass

Technical field

The utility model relates to a kind of interchange overpass, belongs to urban highway traffic field.

Background technology

What in current domestic solution city, crossroad multilevel traffic problem was the most frequently used is build interchange overpass, and diesis shape intercommunicated overpass is immediate prior art with the utility model, its essential characteristic is: the cross four direction direct lane along the main overpass bridge of cross builds 4 U-shaped cross-line overpass bridges, they assume responsibility for tune and the left-hand bend traveling task of through vehicles, simultaneously because their access bridge sets up outside direct lane, go up a slope, descending only occupies area soil, Liang Tiao track, direct lane both sides, what tune of turning took is the upper space of direct lane, not extra land occupation, therefore, it is less than the cloverleaf intercommunicated overpass generally adopted at present that this overpass bridge has floor space, achieve again the object of the full intercommunication of crossroad vehicle simultaneously.But in reality, crossroad in city, by various conditionality, and the cross four direction direct lane not all possessed along the main overpass bridge of cross builds the condition of 4 U-shaped cross-line overpass bridges, many crossroads only possess in both sides, crossing, along the condition of a constructing road U-shaped cross-line overpass bridge, the application of diesis shape intercommunicated overpass is restricted in this case.

Summary of the invention

The purpose of this utility model: when the crossroad in city only possesses in both sides, crossing, during along condition (or the unnecessary four direction in crossroad all builds U-shaped cross-line overpass bridge) of a constructing road U-shaped cross-line overpass bridge, adopt the utility model, vehicle and time bridge intercommunication of main bridge twocouese traveling can be realized, secondary bridge vehicle is passed through by traffic signal control, and its traffic capacity improves more than twice.

The utility model has following characteristics:

1, two U-shaped cross-line overpass bridges (3) are built in the both sides of the main overpass bridge of cross and along two craspedodrome directions of main bridge (1), and the vehicle on two the craspedodrome directions solving main bridge (1) turns left to travel.

2, secondary bridge (2) vehicle is passed through by traffic signal control, and its traffic capacity improves more than twice.

3, can take according to actual conditions: single seat or two U-shaped cross-line overpass bridges extend access bridge length, strengthen the form of cross-line overpass bridge turning radius.

Detailed description of the invention

Contrast accompanying drawing below and elaborate the utility model, the main overpass bridge of cross that the utility model forms primarily of: main bridge (1) and secondary bridge (2), two U-shaped cross-line overpass bridges (3), 4 right-hand rotation ring roads (4), two left rotaring ring roads (5) are formed jointly.

The utility model is implemented by following technical measures: as shown in Figure 1, two U-shaped cross-line overpass bridges (3) are built in the both sides of the main overpass bridge of cross and along two craspedodrome directions of main bridge (1), two U-shaped cross-line overpass bridges (3) are all to do starting point outside main bridge (1) craspedodrome direction lane, access bridge extends outside craspedodrome direction lane, when extend to height at the bottom of bridge meet code requirement apart from main bridge (1) bridge floor height after (as Fig. 2, shown in Fig. 3), the direct lane of main bridge (1) is crossed in tune of turning left, arrive the outside of main bridge (1) opposite craspedodrome direction lane, direct motion situation is formed with opposite craspedodrome direction lane, and along descending outside opposite craspedodrome direction lane, converge with the right-turn lane of opposite craspedodrome direction lane, form the vehicle left-hand rotation U-shaped cross-line overpass bridge of main bridge (1) twocouese.

Main bridge (1) and time bridge (2) four direction respectively build a vehicle right turn ramp (4), right-hand rotation for vehicle travels, the through vehicles of secondary bridge (2) and left turning vehicle are passed through by traffic signal control, build two left rotaring ring roads (5), the vehicle for secondary bridge (2) turns left to travel.

So far, half range diesis shape interchange overpass completes: the vehicle above main bridge (1) is kept straight on, turn left, turning right travels continuously; Vehicle above secondary bridge (2) is turned right and is travelled continuously, craspedodrome and left-hand bend vehicle are passed through by traffic signal control, because only have the signal control of secondary bridge (2) twocouese, so than the signal control time shorten twice of plane cross crossing four direction, bus capacity improves more than twice.

Core of the present utility model is two U-shaped cross-line overpass bridges (3) that Yan Zhuqiao (1) both direction direct lane is built, the left-hand bend that they assume responsibility for main bridge (1) two craspedodrome direction vehicle travels task, simultaneously because they set up outside direct lane, go up a slope, the access bridge of descending only occupies area soil, Liang Tiao track, direct lane both sides, what tune of turning took is that the upper space of direct lane is (as Fig. 2, shown in Fig. 3), not extra land occupation, thus effectively make use of soil, secondary bridge (2) is that plane is passed through completely, not extra land occupation, the traffic capacity improves more than twice,

The utility model has following major advantage:

1, owing to only needing to build two U-shaped cross-line overpass bridges (3) along main bridge (1) both direction direct lane, and the access bridge of U-shaped cross-line overpass bridge (3) only occupies area soil, Liang Tiao track, direct lane both sides, secondary bridge (2) is that plane is passed through completely, not extra land occupation, therefore the utility model greatly reduces floor space.

2, the utility model achieves the current continuously of main bridge (1) all directions, and secondary bridge (2) traffic capacity improves more than twice, improves the traffic of crossroad.

3, two U-shaped cross-line overpass bridges (or U-shaped cross-line tunnel) are symmetrical each other, and appearance is succinctly attractive in appearance, and all directions traffic route is simply clear and definite, and form is basically identical, and human pilot is not easily got lost;

4, the utility model according to on-site actual situations, can be taked: U-shaped cross-line overpass bridge, or the form such as U-shaped cross-line tunnel.

5, the utility model according to on-site actual situations, can be taked: single seat or two U-shaped cross-line overpass bridges extend access bridge length, strengthen the form of cross-line overpass bridge turning radius, as shown in Figure 4.

The utility model is applicable to the crossroad that vehicular traffic in city is large, width of roadway is limited and realizes multilevel traffic.
