Description

A kind of intercommunicated overpass

Technical field

The utility model relates to a kind of urban road bridges, particularly a kind of intercommunicated overpass.

Background technology

Present urban road more and more blocks up, particularly crossroad, and red light more waits longer, adopt all pass overpass, effectively can solve the problem by red lights such as crossroads, significantly improve the traffic efficiency by crossroad, existing all pass overpass complex structure, the mode of general employing multilayer viaduct, fabric structure can be caused higher, affect neighboring buildings daylighting general, and long construction period, when all pass overpass construction is carried out for old road mouth, a lot of problem can be run into .

Utility model content

Technical problem to be solved in the utility model is to provide a kind of all pass overpass, need not wait the intercommunicated overpass of red light, and pontic is all at below ground.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: intercommunicated overpass is located on crossroad, and intercommunicated overpass comprises first floor passage, second layer passage, floor traffic road; First floor passage, second layer passage are all located at below ground, and floor traffic road is established on the ground, and first floor passage is below second layer passage; First floor passage underground circular road, first floor passage is communicated with second layer passage, floor traffic road respectively by leading the way; Second layer passage is sunk type passage, and second layer passage and floor traffic road weigh straight; First floor passage and intersection, floor traffic road far from ground four meters, second layer passage is apart from nine meters, ground; The first floor passage carriageway width that goes in ring is seven meters, and radius of a circle is 14 meters, and the carriageway width in described second layer passage, floor traffic road is eight meters.

The all pass overpass advantage that the utility model provides is, first floor passage, second layer passage is at below ground, when needing to turn left from the first craspedodrome direction to the second craspedodrome direction or turn right, lead the way by first and enter first floor passage and to lead the way from second and enter floor traffic road, when needing to turn left from the second craspedodrome direction to the first craspedodrome direction or turn right, lead the way by second and enter first floor passage and to lead the way from first and enter first floor passage, when needing to the first craspedodrome direction running, travelled by second layer passage, when needing to the second craspedodrome direction running, travelled by floor traffic road.

First floor passage and intersection, floor traffic road far from ground four meters, second layer passage is apart from nine meters, ground, the first floor passage carriageway width that goes in ring is seven meters, radius of a circle is 14 meters, the carriageway width in described second layer passage, floor traffic road is eight meters, design is more reasonable, can make full use of crossroad original path.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is described in further detail:

Fig. 1 is top view figure of the present utility model.

Fig. 2 is A-A profile of the present utility model.

Fig. 3 is the utility model B-B profile.

Detailed description of the invention

As in Fig. 1,2,3, intercommunicated overpass first floor passage a, second layer passage b, floor traffic road c; Central authorities' divided lane 2 is the track of floor traffic road c, second layer passage b relative transit, described first floor passage a, second layer passage b are all located at ground less than 1, floor traffic road c is located on ground 1, first floor passage a is below second layer passage b, first floor passage a underground circular road, and lead the way by first that d is communicated with second layer passage b, the f that leads the way by second is communicated with floor traffic road c; Second layer passage b is sunk type passage, and described second layer passage b connects two current crossings of the first craspedodrome direction h1, and described floor traffic road c connects two current crossings of the second craspedodrome direction h2, and the first craspedodrome direction h1 is perpendicular to the second craspedodrome direction h2;

First floor passage a and c intersection, floor traffic road far from ground four meters, second layer passage b is apart from nine meters, ground;

The first floor passage a carriageway width that goes in ring is seven meters, and radius of a circle is 14 meters, and the carriageway width of described second layer passage b, floor traffic road c is eight meters.

The direction of arrow is vehicle pass-through direction, when vehicle to be turned left to the second craspedodrome direction h2 by the first craspedodrome direction h1 or turns right, enters first floor passage a from first of the second layer passage b d that leads the way, then enters floor traffic road c from second f that leads the way; When needing to turn left from the second craspedodrome direction h2 to the first craspedodrome direction h1 or turn right, first floor passage a is entered from second of the floor traffic road c f that leads the way, first floor passage b is entered again from first d that leads the way, when needing to the first craspedodrome h1 direction running, travelled by second layer passage b, when needing to travel to the second craspedodrome direction h2, travelled by floor traffic road c.

Structure in this example is only illustrating and explaining for claim, so that mass reading is understood, should not be considered as the restriction for claim, and the scope that protection domain of the present utility model should be recorded with claim and legal equivalent feature are as the criterion.
