Abstract
The invention discloses a left-turning torodial flyover, which is provided with a viaduct (1), a viaduct ramp (2), a ground lane (3) and an underground lane (4). The invention is characterized in that vehicles needing to turn left in intersections can pass through a lane (5) on the viaduct (1) by 270 degrees of left-turning to drive down, vehicles needing to turn right directly pass through the lane (5) on the viaduct to drive down; the ground lane (3) and the underground lane (4) are straight lanes. The flyover of the invention has small floor area and low cost; the flyover uses underground, ground and in the air Trinitarian design to facilitate the turning vehicles and straightly traveling vehicles not to cross, and north-south traveling vehicles and east-west traveling vehicles not to cross, so vehicles do not need to stop, thus particularly facilitating the driving of left-turning vehicles; in addition, no complex road sign exists, thus achieving the purposes of time-saving, labor-saving and signal-saving, and thoroughly solving the traffic congestion of vehicles.
Description
Technical field
The present invention relates to the overpass bridge in a kind of urban traffic, relate in particular to a kind of left-turning torodial flyover.
Background technology
Along with increasing of city vehicle, the situation of traffic congestion is serious day by day, not only wastes time and energy during by manpower and the control of red street lamp in special crossroad, and steered vehicle especially the inconvenience of left turning vehicle increased the weight of the phenomenon of traffic jam.Overpass bridge is set at the road junction place can alleviates congestion and Vehicular turn problem, but existing overpass bridge level is many, complex structure, floor space is big, the cost height, influence is promoted, and the overpass bridge of simple layer is also arranged, and cost is low, and level is few; But the design of these overpass bridges make left turning vehicle detour far away or turn too urgent; Fundamentally do not solve the vehicle left steering and take time and effort problem with urban traffic blocking.
Summary of the invention:
Technical problem to be solved by this invention provides a kind of left-turning torodial flyover, has overcome the shortcoming of above-mentioned existing overpass bridge.
Technical problem to be solved by this invention is achieved through the following technical solutions:
A kind of left-turning torodial flyover, be provided with viaduct, viaduct ramp, track, ground and underground track, it is characterized in that crossroad need left turning vehicle can be descending by the 270 ° of left-hand rotations in track on the described viaduct, need the right-hand rotation vehicle directly descending by the track on the described viaduct.Track, described ground and described underground track are direct lane.Track, described ground is that the then described underground track of east-west direction is a North and South direction; Track, described ground is that the then described underground track of North and South direction is an east-west direction.This underground, on the ground and aerial Trinitarian design, make bogie car and straightgoing vehicle not intersect, the north and south straightgoing vehicle does not intersect with the thing straightgoing vehicle, and car need not stop through the crossroad; Especially overcome detoured far away or the too urgent problem of turning for the left-hand rotation car, time saving and energy saving.
Described viaduct bridge floor is an annular; The weight of annular design having alleviated viaduct is saved material, to the more convenient safety of the support of viaduct.
Described viaduct track is multiple tracks or two pass, and inside and outside both sides, track are equipped with Cement guard bar.Place, ground, described viaduct ramp separates with guardrail with the track, ground.Described viaduct ramp is positioned at the position of viaduct annulus corner and can takes the circumstances into consideration to extend out.What of track can be designed according to the flow of car with area that the viaduct ramp is positioned at the position of viaduct annulus corner, and the guardrail that is provided with has been protected the safety of car.
Inlet top, described underground track is provided with rain cover.In the time of can preventing sleety weather, the pouring into of rainwater.
Described viaduct bridge floor diameter is determined according to the flow and the load-carrying of car.Described left-turning torodial flyover can change right-hand rotation annulus overpass bridge according to the difference of driving habits into, therefore is applicable to the country that left lateral is sailed, the needs that right turn is time saving and energy saving.
The present invention has the following advantages:
Overpass bridge building area of the present invention is little, and cost is low; Utilize underground, on the ground and aerial Trinitarian design, make bogie car and straightgoing vehicle not intersect, the north and south straightgoing vehicle does not intersect with the thing straightgoing vehicle, car need not stop through the crossroad, especially made things convenient for travelling of left turning vehicle, and do not have complicated road sign, reached and save time, economize the purpose that Ren He economizes signal, thoroughly solved the vehicle problem of blocking up.
Description of drawings
Fig. 1 is a left-turning torodial flyover structural representation of the present invention
The specific embodiment
Left-turning torodial flyover structural representation as shown in Figure 1 as can be known, this left-turning torodial flyover, be provided with viaduct 1, viaduct ramp 2, track, ground 3 and underground track 4, it is characterized in that crossroad need left turning vehicle can be descending by the 270 ° of left-hand rotation routes 11 in the track on the described viaduct, need the right-hand rotation vehicle directly descending by the track right-hand rotation route 10 on the described viaduct.Track 3, described ground and described underground track 4 are direct lane.Track, described ground 3 is an east-west direction, and described underground track 4 is a North and South direction.This underground, on the ground and aerial Trinitarian design, make bogie car and straightgoing vehicle not intersect, the north and south straightgoing vehicle does not intersect with the thing straightgoing vehicle, and car need not stop through the crossroad; Especially detoured far away or the too urgent problem of turning have been overcome for the left-hand rotation car.
Described viaduct bridge floor is an annular; The weight of annular design having alleviated viaduct is saved material, to the more convenient safety of the support of viaduct.
Described viaduct track 5 is multiple tracks or two pass, and inside and outside both sides, track are equipped with Cement guard bar 6.Place, ground, described viaduct ramp separates with guardrail 7 with the track, ground.Described viaduct ramp is positioned at the position 8 of viaduct annulus corner and can takes the circumstances into consideration to extend out.What of track can be designed according to the flow of car with area that the viaduct ramp is positioned at the position of viaduct annulus corner, and the guardrail that is provided with has been protected the safety of car.Inlet top, described underground track is provided with rain cover 9, in the time of can preventing sleety weather, and the pouring into of rainwater.
