Abstract

The utility model relates to a super minisize crossroads which adopts intersperse spanning structure. A left turning special traffic lane is arranged to connect with an overall second layer bridge plane and a third layer bridge plane for solving the cross trouble of left turning and straight ride. The layers of crossroads are reduced into two layer bridge planes. If the original bridge plane is subsidized by five meters, the overall height of the crossroads is about five meters, thereby minimizing the occupied area and space volume. The bridge width is less than that of the original road without occupying new land and detaching the house on two sides of crossroad. Four directions are avaible in left, right, forward and turning. Sixteen directions are free to ride, thereby guaranteeing riding safety, increasing traffic capacity and greatly reducing construction cost.

Description

The superminiature overpass bridge

Technical field

The utility model relates to a kind of overpass bridge.

Background technology

Existing overpass bridge level is many, and floor space is big, is generally four to six layers, land acquisition, and removal roadside buildings thing is long in time limit, the expense height ... limited to by this, can only build on the outskirts of a town mostly, can't solve the urban transit system congestion.

Summary of the invention

In order to overcome above-mentioned deficiency, the utility model provides a kind of superminiature overpass bridge, just can reach the purpose that level is few, floor space is little, expense is low.

The technical scheme in the invention for solving the technical problem: adopt cross-linking to cross over structure, the left-hand rotation dedicated Lanes are set, total second layer bridge floor and the 3rd layer of bridge floor are linked together, solve and craspedodrome intersects a difficult problem, the number of plies of overpass bridge is reduced to has only two-layer bridge floor.Add also only three layers on road surface, height overall has only about ten meters.As former road surface is sunk five meters, then this overpass bridge height overall also has only about five meters.Highly reduce, span descends naturally thereupon significantly; And this structure is simplified and has been eliminated circuitous bend of butterfly type and rotating disk layout, thereby makes floor space and spatial volume realize minimizing, and so, almost such overpass bridge all can be built in ten crossings of all traffic lights of bed rearrangement city.Driving is till that time met red parking never again and has been given way.

The enlarging of first floor bridge floor can be built or depend on to pedestrian overcrossing in addition,

The utility model beneficial effect is summarized as follows:

1, bridge is wide is no more than former having a lot of social connections, and does not newly levy the soil;

2, the house, both sides, crossroad of not removing.As need not sinking, can motionless road surface, the construction of not closing a road to traffic can realize producing member outside the venue, utilizes to lift night successfully;

3, reduce engineering cost significantly, the investment of building a bridge in the past can be built some bridges now, does not have traffic lights and has created condition for realizing the whole city;

4, four direction is sent a car, left, to the right, forward, tune, ten six directions are taken their own roads, and guarantee traffic safety;

5, improve road speed, if the bed rearrangement city does not all have traffic lights, how many road speeds do not know to improve doubly;

6, increase traffic capacity, can build subway and viaduct less;

7, optimize and simplify traffic administration.

Illustrate that accompanying drawing is the utility model embodiment schematic diagram.Fig. 1 is the panorama schematic diagram, and Fig. 2 is front elevational schematic (A), and Fig. 3 is a schematic side view, and Fig. 4 is innings schematic diagram (A) that is periphery in overlooking, and Fig. 5 is for overlooking outer shroud schematic layout pattern (B), and Fig. 6 is front elevational schematic (B), and Fig. 7 is the sunk type schematic diagram.

1. bottom road surfaces among the figure, 2. total second layer bridge floor, 3. total the 3rd layer of bridge floor, 4,5. cross over cross-linking left-hand rotation dedicated Lanes.

The specific embodiment

Left-hand rotation dedicated Lanes (4) (5) are set, total second layer bridge floor (2) and the 3rd layer of bridge floor (3) are linked together.

Claims

1, a kind of superminiature overpass bridge is by the road surface, total second layer bridge floor, and total the 3rd layer of bridge floor formed, and it is characterized in that: the left-hand rotation dedicated Lanes are crossed over to intert total second layer bridge floor and the 3rd layer of bridge floor are linked together.
