Abstract

The utility model relates to a full-functional high-speed overpass which is divided into a main way on the overpass and a main way below the overpass, wherein the main way on the overpass is a straight-line twin-row way, and the middle part of the ground main way below the overpass is a circular ring type single-row rotary disc. The two main ways are respectively provided with a right turning way, and both of the two right turning ways are respectively externally tangent to the rotary disc. The space of the rotary disc corresponding to the main road on the overpass is provided with four slope ways for the left turn and the u-turn of vehicles from the inner diameter of the rotary disc to the main way on the overpass, and the outer sides of the two main ways are provided with footways. The overpass has the advantages of low cost, small land-area occupation, complete functions, short running routes, time saving, safe running of vehicles and no occurrence of vehicle crashing accidents, extends in all directions, and reduces energy consumption.

Description

Global function high speed overpass bridge

(1), technical field:

The utility model belongs to a kind of means of transportation, is specifically related to a kind of overpass bridge.

(2), technical background:

In the Modern Traffic approach system, in order to adapt to increasing high vehicle speeds, overpass bridge miscellaneous has been built in domestic and international flourishing city, directional type is arranged, winding type, annular or rhombus bridge, its common defects is an insufficiency, vehicle can not directly turn left in bridge or the tune backward going, when needing left steering or tune backward going, must take a roundabout way and to realize, Chinese patent has been announced a kind of " high-speed directly-steering overpass " (ZL001052705), though it has solved the problem of carrying out left steering in overpass bridge, but one of its defective is still unresolved tune backward going problem, two of defective is that the required land area of bridge construction is big, and investment is high, and route or travel by vehicle is long.

(3), summary of the invention:

The purpose of this utility model is for solving all defect of above-mentioned overpass bridge, design a kind of occupation of land less, construction cost is low and driving vehicle can craspedodrome fast in bridge, the global function high speed overpass bridge of right turn, left steering and tune backward going.

Design scheme of the present utility model is:

This overpass bridge divides on the bridge, following two main stems of bridge, is decided to be first main stem with the north-south main stem, is decided to be second main stem with the East and West direction main stem, and this first main stem is located on the overpass bridge for dividing the straight line two-way street of going up trade and following trade; The middle part of second main stem is a circular ring type single file rotating disk, is located on the ground under the overpass bridge; At two main stems, be respectively equipped with the right turn road, all outer rotating disk that is cut in this right turn road; The pairing space of first main stem on rotating disk and bridge, first main stem on from the rotating disk internal diameter to bridge, be provided with four ramps, wherein turn left for the vehicle that the first main stem both direction on the bridge comes in two ramps, and the vehicle left steering that other two ramps are then come for the second main stem both direction uses and the head end operation of first main stem uses; The outside at two main stems is provided with the sidewalk.For making pedestrains safety, the two-way street place at the second main stem two ends establishes underground pedestrian passageway; Under the bridge of first main stem, then establish the ground cross walk.

Present design can also be with the location swap of above-mentioned first main stem and second main stem, and promptly the circular ring type rotating disk is built on the overpass bridge, and the duplicate rows linear road is built on the ground, and this scheme is applied in the transformation of original road more and builds bridge.

This overpass bridge cost is low, and the land occupation area is few, and is multiple functional, from the vehicle that the East, West, South, North direction is come, all can keep straight on, right turn, left steering and tune at this, and be to extend in all direction, and travel route is short, promptly saves time, and cuts down the consumption of energy again; Vehicle driving safety, it all is one-way street that the vehicle that its all directions are come travels in right turn, left steering or tune, car accident can not occur.

(4), description of drawings:

Fig. 1 establishes the two-way overpass bridge schematic diagram of straight line on the bridge.

Fig. 2 comes the craspedodrome of vehicle, the left and right route schematic diagram that turns to, reverses end for end backward going for Fig. 1 east.

Fig. 3 comes the craspedodrome of vehicle, the left and right route schematic diagram that turns to, reverses end for end backward going for Fig. 1 south.

Fig. 4 is located at overpass bridge schematic diagram on the bridge for the circular ring type rotating disk.

(5), the specific embodiment:

This overpass bridge divides on the bridge, following two main stems of bridge, is decided to be first main stem 1 with the north-south main stem, is decided to be second main stem 2 with the East and West direction main stem, and this first main stem is located on the overpass bridge for dividing the straight line two-way street of going up trade and following trade; The middle part of second main stem 2 is a circular ring type single file rotating disk 3, is located on the ground under the overpass bridge; At two main stems, be respectively equipped with right turn road 4, all outer rotating disk 3 that is cut in this right turn road 4; First main stem, 1 pairing space on rotating disk 3 and bridge, first main stem 1 on from the internal diameter of rotating disk 3 to bridge, if four the ramp 5,6,7,8, the vehicle left steering that comes for the first main stem north and south both direction of ramp 5,6 wherein, the vehicle left steering that 7,8 in ramp is come for the second main stem thing both direction use and the vehicle of first main stem under go up bridge tune use again behind the bridge; In the outside of two main stems, be provided with sidewalk 9; For making pedestrains safety, the two-way street place at the second main stem two ends establishes underground pedestrian passageway 10; Under the bridge of first main stem 1, then establish ground cross walk 11.

Claims

1, a kind of global function high speed overpass bridge divides on the bridge, following two main stems of bridge, is decided to be first main stem with the north-south main stem, is decided to be second main stem with the East and West direction main stem, it is characterized in that:

A. this first main stem is located on the overpass bridge for dividing the straight line two-way street of going up trade and following trade; The middle part of second main stem is a circular ring type single file rotating disk, is located on the ground under the overpass bridge;

B. at two main stems, be respectively equipped with the right turn road, all outer rotating disk that is cut in this right turn road;
