Abstract

The invention relates to a 12 direction overpass. The overpass is on the ground which is corresponding to a crossroad, and is built with an uphill approach bridge for uphill climbing, the tail end of the uphill approach bridge is respectively connected with a right-turning roadway which is provided for right-turning and is tower above the ground and a straight and left-turning roadway; the front part of the straight and left-turning roadway is connected with a second tier of the bridge, which spans from above the left to right roadway, then a downhill slope traverses from below the second tier of the bridge which is for right to left running and is connected with another uphill approach bridge, and then is superposed respectively with the straight roadway and the left-turning roadway which are connected with the downhill approach of the bridge; space is spared and a non-motorized vehicle lane and a walkway are disposed below the uphill and downhill approach bridges, thereby forming the complete 12 direction overpass. The overpass has advantages of simple structure, convenient driving, low cost, realizing arbitrary driving of 12 directions, avoiding level crossing and the phenomenon of getting lost, is an ideal overpass building program and is highly worthy of popularization and application.

Description

12-direction overpass

Technical field

The present invention relates to a kind of overpass bridge of crossroad, is the 12-direction overpass that a kind of 12 directions all can be unimpeded.

Background technology

At present, the overpass bridge in the intersection, two road, of a great variety, its complex structure, if not very familiar slightly will going in the wrong direction, this mainly be because the complex structure of overpass bridge institute extremely, this baroque overpass bridge, not only travel and be easy to get lost, and it involves great expense, and floor space is big, to this, at present, also there is not very desirable way to solve.

Summary of the invention

In order to solve the problem that present overpass bridge exists, the invention provides a kind of 12-direction overpass, simple in structure, the convenience of travelling of this bridge, cheap, 12 directions are travelled arbitrarily, at grade intersection can not take place, and are difficult for taking place lost phenomenon, be present desirable overpass bridge bridging scheme, have application value.

The present invention solves the concrete scheme that its technical problem adopts: this overpass bridge comprises first floor bridge floor, second layer bridge floor, right lateral track, keep straight on, turn left track and uplink and downlink ramp five parts; It is characterized in that: locate at the parting of the ways to have the upward slope access bridge of upward slope on the corresponding ground, the end of upward slope access bridge is connected with craspedodrome, the track of turning left respectively with to the overhead track of turning right of right travel; What keep straight on, turn left the anterior connection in track promptly is second layer bridge floor, second layer bridge floor is behind the track that crossing-above travels from left to right, after pass the second layer bridge floor that travels from right to left with another upward slope access bridge is connected down, the direct lane that is connected with the descending access bridge and the track of turning left overlap descending respectively again; Leave the space below the upper and lower sloping access bridge, and be provided with nonmotorized vehicle lane and track, pedestrian ground, these have promptly formed complete 12-direction overpass.

Its using method is like this, be signal only below with the motor-driven vehicle going route of North and South direction, (the driving method of crossroad four direction is all identical) when motor vehicle arrives the crossroad from south to north, upward slope access bridge 1 in the elder generation, behind the last access bridge, if keep straight on and just the track crossing-above of turning left, after the leap, below the track of travelling from east to west, pass from travelling from west to east, under wear after, can keep straight on and turn left, if right lateral can directly be turned right from upward slope access bridge 1; Pedestrian and non motorized vehicle, walking is on the track, ground.

Its beneficial effect is: simple in structure, the convenience of travelling of this bridge, and cheap, can 12 directions travel arbitrarily, at grade intersection can not take place, be difficult for lost phenomenon takes place, be present desirable overpass bridge bridging scheme, have application value.

Description of drawings

The invention will be further described below in conjunction with drawings and the embodiments;

Accompanying drawing is a structural principle schematic diagram of the present invention;

Among the figure, 1 upward slope access bridge, 2 tracks of turning right, 3 keep straight on and the tracks of turning left, 4 second layer bridge floors, 5 first floor bridge floors, 6 tracks from left to right, 7 second layer bridge floors, 8 descending access bridges.

The specific embodiment

In the drawings, this overpass bridge comprise first floor bridge floor 5, second layer bridge floor 7, right lateral track 2, keep straight on, turn left track 3 and uplink and downlink ramp 1,8 five parts; It is characterized in that: locate at the parting of the ways to have the upward slope access bridge 1 of upward slope on the corresponding ground, the end of upward slope access bridge 1 is connected with craspedodrome, the track 3 of turning left respectively with to the overhead track 2 of turning right of right travel; The track 3 anterior connections of keeping straight on, turn left promptly are second layer bridge floors 4, second layer bridge floor 4 is from track 6 that crossing-above travels from left to right, descending is from passing the second layer bridge floor 7 that is connected with another upward slope access bridge that travels from right to left down, from under pass after, the direct lane that is connected with descending access bridge 8 and the track of turning left overlap respectively; Leave the space below the upper and lower sloping access bridge 1,8, and be provided with nonmotorized vehicle lane and track, pedestrian ground, these have promptly formed complete 12-direction overpass.

In the drawings, only mark four/part of this bridge, all the other are all symmetry mark, Therefore, omited.

In the drawings, its using method is like this, is signal with the motor-driven vehicle going route of North and South direction only below, (crossroad four direction driving method is all identical) when motor vehicle b when the direction of arrow arrives the crossroad from south to north, upward slope access bridge 1 in the elder generation, behind the last access bridge, if keep straight on and just track 6 crossing-aboves of turning left, after the leap from travelling from west to east, below the track (second layer bridge floor) of travelling from east to west, pass, under wear after, can keep straight on and turn left, arrive b ' c ' respectively and locate; If right lateral can directly be turned right from upward slope access bridge 1; Pedestrian and non motorized vehicle, walking is on the track, ground.

Claims

1. 12-direction overpass, this overpass bridge comprises first floor bridge floor (5), second layer bridge floor (7), right lateral track (2), keep straight on, turn left track (3) and uplink and downlink ramp (1,8) five parts; It is characterized in that: locate at the parting of the ways to have the upward slope access bridge (1) of upward slope on the corresponding ground, the end of upward slope access bridge (1) is connected with craspedodrome, the track of turning left (3) respectively with to the overhead track of turning right of right travel (2); What craspedodrome, the track of turning left (3) front portion connected promptly is second layer bridge floor (4), second layer bridge floor (4) is behind the track (6) that crossing-above travels from left to right, after pass the second layer bridge floor (7) that travels from right to left with another upward slope access bridge (8) is connected down, the direct lane that is connected with descending access bridge (8) and the track of turning left overlap descending respectively again; Upper and lower sloping access bridge leaves the space below (1,8), and is provided with nonmotorized vehicle lane and track, pedestrian ground, and these have promptly formed complete 12-direction overpass.
