Description
Technical field
The utility model relates to highways and urban roads field of engineering technology, relates in particular to a kind of clover blade profile grade separation structure.
Background technology
Common clover blade profile grade separation operated by rotary motion has four loop ramps, for the less four-legs intersection of the flow that turns left.It has the advantages such as level is low, cost province; Due to annular left rotaring ring road first-in last-out, the spacing of entrance and outlet is shorter, causes into main line and the vehicle that goes out main line and interweaves, thereby affect the traffic capacity of main line.
When ring road access spacing is near, ring road access vehicles passing in and out disturbs when larger main line traffic, and collector can be set, and guarantees quick, the unimpeded and safety of main line.Collector generally adopts two-way traffic, should treat according to access with being connected of main line, and acceleration and deceleration track is set, and correspondingly, has virtually increased the cost of construction investment.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of clover blade profile grade separation structure, by roundabout clover blade profile ring road, arrange, eliminated main line access in the past first-in last-out, the shortcoming of spacing deficiency, overcome the full clover blade profile of the collector graded crossing loop ramp serious shortcoming of phenomenon that interweaves first-in last-out has not been set, also the collector that has overcome the full clover blade profile ring road that collector the is set phenomenon that interweaves, guarantees quick, unimpeded, the safety of main line vehicle.
In order to achieve the above object, the purpose of this utility model is achieved through the following technical solutions:
A kind of clover blade profile grade separation structure, wherein, comprise the first crossing main trunk road and the second main trunk road, in four quadrants that form, be respectively equipped with a right-hand rotation ring road between described the first main trunk road and described the second main trunk road, described clover blade profile grade separation structure also comprises four left rotaring ring roads, and every described left rotaring ring road is across two adjacent described quadrants; Described left rotaring ring road comprises turning left roundabout section and left-hand rotation ring segment, and the entrance that described left-hand rotation is roundabout section communicates with the described right-hand rotation ring road that left turning vehicle sails out of track, and the outlet of described left-hand rotation ring segment communicates with the target track of described left turning vehicle; Roundabout section of outside that is positioned at the described left-hand rotation ring segment of the described quadrant that coexists with it of described left-hand rotation.
Above-mentioned clover blade profile grade separation structure, wherein, across described the second main trunk road, wears described the first main trunk road or upper across described the second main trunk road on described the first main trunk road under roundabout section of described left-hand rotation.
Above-mentioned clover blade profile grade separation structure, wherein, described right-hand rotation ring road is that one section of circular arc or multi-section circular arc join and form.
Compared with the prior art, the beneficial effects of the utility model are:
-do not need to arrange collector;
Between-left rotaring ring road access, without the section of interweaving, improved the traffic capacity of ring road and main line;
-occupation of land, building height, construction costs are a little less than the clover blade profile graded crossing that collector is set.
Accompanying drawing explanation
The accompanying drawing that forms a part of the present utility model is used to provide further understanding of the present utility model, and schematic description and description of the present utility model is used for explaining the utility model, does not form improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of a specific embodiment of the utility model clover blade profile grade separation structure;
Fig. 2 is the structural representation of another specific embodiment of the utility model clover blade profile grade separation structure.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
It should be noted that, in the situation that not conflicting, embodiment and the feature in embodiment in the utility model can combine mutually.
See figures.1.and.2, the utility model clover blade profile grade separation structure comprises the first crossing main trunk road 1 and the second main trunk road 2, in four quadrants that form, is respectively equipped with a right-hand rotation ring road 3 between the first main trunk road 1 and the second main trunk road 2.This clover blade profile grade separation structure also comprises four left rotaring ring roads, and every left rotaring ring road is across two adjacent quadrants.Left rotaring ring road comprises turning left roundabout section 41 and left-hand rotation ring segment 42, the entrance turning left roundabout section 41 communicates with the right-hand rotation ring road 3 that left turning vehicle sails out of track, the outlet of left-hand rotation ring segment 42 communicates with the target track of left turning vehicle, the outside of the left-hand rotation ring segment 42 that is positioned at the quadrant that coexists with it for roundabout section 41 of turning left.
In preferred embodiment of the present utility model, continue referring to shown in Fig. 1 and Fig. 2, on the first main trunk road 1, across the second main trunk road 2, turn left roundabout section to wear for 41 times the first main trunk road 1 or upper across the second main trunk road 2.
Further, right-hand rotation ring road 3 is that one section of circular arc or multi-section circular arc join and form, and can know from experience, wherein in the structural difference of its difference in Fig. 1 and Fig. 2, the ring road 3 of turning right in Fig. 1 is one section of complete circular arc, and the ring road 3 of turning right in Fig. 2 is joined and formed by multi-section circular arc.
From above-described embodiment, can find out, advantage of the present utility model is:
-do not need to arrange collector;
Between-left rotaring ring road access, without the section of interweaving, improved the traffic capacity of ring road and main line;
-occupation of land, building height, construction costs are a little less than the clover blade profile graded crossing that collector is set.
Above specific embodiment of the utility model be have been described in detail, but the utility model is not restricted to specific embodiment described above, it is just as example.To those skilled in the art, any equivalent modifications and alternative also all among category of the present utility model.Therefore,, not departing from the equalization conversion of having done under spirit and scope of the present utility model and revising, all should be encompassed in scope of the present utility model.
