Summary of the invention

The purpose of this invention is to provide the overpass bridge of being with direct lane and command lamp on a kind of rotary island, it is optimized grade separation bridge construction and command lamp, makes its reasonable cooperation, improves the traffic capacity of overpass bridge.

The object of the present invention is achieved like this: the overpass bridge of band direct lane and command lamp on a kind of rotary island, it is two layers of overpass bridge, wherein there is one deck to have rotary island, the road of that layer of band island is not major trunk roads, the direct lane of major trunk roads is directly passed a bridge, a major trunk roads left side, turn right, head end operation through rotary island detour by, the craspedodrome of that layer of band island, left and right sides turning vehicle all passes through through rotary island, also be provided with two-way craspedodrome motorway perpendicular to the major trunk roads direction in the rotary island plane, the two ends of craspedodrome motorway are connected on the plane of rotary island and produce four crosspoints with rotary island, be connected on the motorway of vertical arterial highway, all directions track is provided with stop line before each crosspoint, and each place, crosspoint is provided with command lamp, command lamp has only green light and two kinds of signals of greenish-yellow lamp, and each command lamp signal unanimity.The independent bridge construction of described direct lane or with rotary island be one, the rotary island corresponding road surface is widened, and the direct lane or be separated out direct lane with the isolation strip of drawing.

The present invention has following advantage and good effect:

It makes its two reasonable cooperation by grade separation bridge construction and command lamp are done suitable improvement, improves the traffic ability.Overpass bridge all is positioned at traffic intersection, and ground, space an inch of land is an inch of gold are very important to their reasonable utilization herein, the general occupation of land of overpass bridge is also bigger, so to the drop optimization of overpass bridge, all can improve the traffic ability greatly, produce huge economic and social benefit.

Existing similar overpass bridge has only the major trunk roads straightgoing vehicle directly to pass a bridge, and the straightgoing vehicle of the vertical arterial highway rotary island that need detour could pass through, and the pressure of rotary island is overweight, results in blockage.The present invention is not increasing the overpass bridge number of plies and access bridge, need not under the situation of too much investment, increase the craspedodrome motorway of vertical arterial highway, the craspedodrome motor vehicle of level and vertical both direction is all passed through smoothly, turning vehicle again rotary island detour by, alleviate rotary island and pressure, improved the traffic capacity of overpass bridge.

Description of drawings

Fig. 1 is a schematic diagram of the present invention;

The specific embodiment

Describe the present invention in detail below in conjunction with drawings and Examples:

As shown in Figure 1, the overpass bridge of band direct lane and command lamp on a kind of rotary island, it is two layers of overpass bridge, wherein there is one deck to have rotary island (Fig. 1 has rotary island at the middle and upper levels), the road of that layer of band island is not major trunk roads (being the road of the vertical of underground passage formula among Fig. 1), and the direct lane of major trunk roads is directly passed a bridge, the left and right turning of major trunk roads, head end operation through rotary island detour by, craspedodrome, the left and right sides turning vehicle of that layer of band island all pass through through rotary island.Also be provided with two-way craspedodrome motorway AB, CD, the two-end-point A of craspedodrome motorway, B perpendicular to major trunk roads direction (being horizontal direction among Fig. 1) in the rotary island plane; C, D, be connected on the plane of rotary island and produce four crosspoint A, B, C with rotary island, D, be connected on the motorway of vertical arterial highway, all directions track is provided with stop line 2 before each crosspoint, and each place, crosspoint is provided with command lamp 1, command lamp has only green light and two kinds of signals of greenish-yellow lamp, and each command lamp signal unanimity; At the place, four crosspoints of rotary island and craspedodrome motorway, it is current that green light signals is permitted vertical arterial highway direction straightgoing vehicle, greenish-yellow modulating signal, and the loop wire car is current on the allowance rotary island; The straightgoing vehicle of the vertical arterial highway of green light signals is preferential, and greenish-yellow modulating signal loop wire car is preferential; When the opposing party does not have car, under the condition that guarantees safety, P Passable, the opposing party has the Che Shifei prior-vehicle to be parked in the stop line.(dotted line is the track lines of drawing on the bridge floor among the figure, is not the pontic outline line.)

Described craspedodrome motorway does not account for rotary island loop wire track, and whole rotary island loop wire number of track-lines remains unchanged.This direct lane is bridge construction (as shown in Figure 1) separately, can be one with rotary island also, and the rotary island corresponding road surface is widened, and the direct lane or be separated out direct lane with the isolation strip of drawing.

It is suitable for the transformation of 40 overpass bridges in east, Beijing, under the present situation of former bridge, builds each small-sized viaduct 3 of east-west direction uplink and downlink again, 4, as the craspedodrome motorway, and this command lamp and stop line are set, then can constitute overpass bridge of the present invention at corresponding inlet and crosspoint.Certainly, it also can be by this structure, at the newly-built overpass bridge in other place.
