Description

The double-deck all-arc interwine flyover crossing of omni-bearing directional intercommunication bridge

Technical field

The utility model relates to a kind of road overpass, relates in particular to the double-deck all-arc interwine flyover crossing of omni-bearing directional intercommunication bridge.

Background technology

Existing directed shape interchange is by main line, formed by cross link and direct directed ring road.The characteristics of directed shape interchange mainly contain: left rotaring ring road is directly from the main line and the highway left side discrepancy that intersected; The left rotaring ring road steering angle is generally less than 90 °, and the horizontal curve curve is bigger.Its weak point: the bridge engineering amount is bigger, and it is longer to lead the way, and cost is higher.

Directed shape interchange is commonly used following several form:

1. double-deck directed shape interchange

Main line and be sigmoid curve by cross link, each infall is double-deck bridge crossing, as shown in Figure 1.Its characteristics are: each crosspoint disperses, and bridge quantity is more, but highly lower.

2. three layers of directed shape interchange

Main line is a straight line, is sigmoid curve by cross link, and double-deck bridge crossing is established in the two-way intersection; Article four, left rotaring ring road and main line intersect at a place, establish three layers of bridge, as shown in Figure 2.Its characteristics are: bridge crossing is more concentrated, and bridge is higher and negligible amounts mostly is double exit and entrance by cross link, and is unfavorable in driving.

3. four layers of directed shape interchange

Main line, be straight line, main line, intersected at a place, establish four layers of bridge, as shown in Figure 3 by cross link and four left rotaring ring roads by cross link.Its characteristics are: linear compactness, and bridge quantity is few; But the number of plies is more, the bridge construction complexity, and difficulty of construction is big, and investment is high.

In sum, the mode of wagon flow is organized in existing directed shape interchange, mainly is to realize by the bridge of the different numbers of plies, all exists floor space big, plane form complexity, the fuzzy deficiency that waits of cost height and direction of traffic.

More than the concrete weak point of three kinds of directed shape interchanges mainly be following some:

One, the deficiency on the traffic streamline: left turn ramp is come in and gone out from the left side, does not meet the custom of coming in and going out in the driver right side.

Two, above three kinds of directed grade separations, the core organizes the plane form floor space of traffic bigger, and the application in the urban core district is difficulty comparatively.

Three, can't accomplish the directed four-way intercommunication of full-bridge, can only the three-dimensional intercommunication.

Summary of the invention

Goal of the invention of the present utility model is to provide the double-deck all-arc interwine flyover crossing of a kind of omni-bearing directional intercommunication bridge, its line style smoothness, compact in design, fast terse, be specially adapted to the usual friendship transformation of old urban area, big and medium-sized cities, can effectively alleviate congested in traffic phenomenon, have remarkable economical, society, environmental benefit.

The utility model solves the problems of the technologies described above by following technical proposals: the double-deck all-arc interwine flyover crossing of omni-bearing directional intercommunication bridge, comprise whereabouts access bridge A, whereabouts access bridge B, whereabouts access bridge C, whereabouts access bridge D and come to access bridge A, come, come, come to access bridge D to access bridge C to access bridge B, described come to go up by right side to left side to access bridge A be communicated with right-turn lane A, direct lane A, left turn lane A and the left back A that changes trains or buses; Described next going up by right side to left side to access bridge B is communicated with right-turn lane B, direct lane B, left turn lane B and the left back B that changes trains or buses; Described next going up by right side to left side to access bridge C is communicated with right-turn lane C, direct lane C, left turn lane C and the left back C that changes trains or buses; Described next going up by right side to left side to access bridge D is communicated with right-turn lane D, direct lane D, left turn lane D and the left back D that changes trains or buses; Described right-turn lane is the right bended arc line, and all the other tracks are left curved arc line.

Described right-turn lane D imports whereabouts access bridge A; Described direct lane D imports whereabouts access bridge B; Described left turn lane D imports whereabouts access bridge C; The described left back D that changes trains or buses imports whereabouts access bridge D.

As preferably, described direct lane A is positioned at the top of left turn lane B and direct lane B, and described left turn lane A is positioned at the top of left turn lane B, left turn lane D and direct lane C; Described direct lane B is positioned at left turn lane C and direct lane C top, and described left turn lane B is positioned at direct lane D top; Described direct lane C is positioned at left turn lane D and direct lane D top, and described left turn lane C is positioned at left turn lane D, left turn lane B and direct lane A top; Described direct lane D is positioned at left turn lane A and direct lane A top, and left turn lane D is positioned at direct lane B top.

Adopt the utility model of the technical program, its beneficial effect is:

1, double-deck all-arc interwine flyover crossing bridge of the omni-bearing directional intercommunication that provides of the utility model and existing overpass bridge are compared, the difference of its maximum is that this bridge type is provided with 360 ° of left back changing trains or buses, can make traveler arrive the destination in road separator left side with nearest distance, reduce running time, save vehicle cost.

2, the traffic streamline of the double-deck all-arc interwine flyover crossing of the omni-bearing directional intercommunication that provides of the utility model bridge adopts the gimmick of plane and space mixed weaving to carry out rationalization, make the bridge type streamline reasonable, driving safety, the order standard, efficient improves, full-bridge is realized front, rear, left and right four-way omni-bearing directional graded crossing, has eliminated conflict point and intertwined point in all crosspoints fully, has reached comprehensive total relief traffic.

3, except that right-turn lane, all the other line styles are left curved arc line, and the driving sight line is good, has improved travel safety.

4, enter overpass bridge after, the same up-hill journey of circuit longitudinal gradient of each travel direction, " low in and high out ", this design feature had both met the security regulations of bend highway section Reduced Speed Now, can effectively shorten the lane auxiliary length that imports point again, made pontic compact more.

5, all import point and all adopt the right side remittance, meet compatriots' driving custom, favourable traffic safety.

6, line style is terse, and travel direction is directly perceived, favourable accurate, quick, safety traffic.

7, core pontic compactness is taken up an area of and is lacked, and landform compliance is strong.

8, pontic simple structure has only two-layerly without exception, saves construction costs, saves operating cost simultaneously.

9, pontic member model kind is few, is convenient to construction, can realize standardized designs, and suitability for industrialized production improves design and construction efficient.

10, bridge type is handsome in appearance, can be urban construction and increases new view.

11, direct lane and left back change trains or buses spatially tangent non-intersect.All driving route planes, core position are arc, compact conformation, and sight line is open.
