Abstract

The utility model mainly relates to a flyover which has a three-layer structure. The flyover mainly comprises a lower straight-going lane, a ground roundabout lane and an upper straight-going lane, wherein the ground roundabout lane is arranged on the ground; the lower straight-going lane is arranged below the ground roundabout lane; the upper straight-going lane is arranged above the ground roundabout lane; and the lower straight-going lane is perpendicular to the upper straight-going lane. According to the flyover, the problems of the conventional flyover, such as complicated structure, high manufacturing cost and large occupied area, are solved; and the flyover is suitable to popularize and apply.

Description

A kind of overpass bridge

Technical field

The utility model relates generally to a kind of overpass bridge, relates to particularly that direct lane is established in a kind of rotary island top and below, rotary island is realized the overpass bridge that car plane turns to.

Background technology

At present, the improving constantly of Along with people's living standard, the private car retention is increasingly high, and the urban traffic blocking problem is also serious day by day.If the vehicle clogging ubiquity that urban traffic demonstrates when road intersects is in the morning and evening peak period then even more serious.Usually all be now utilize electronic signal light according to vehicle flowrate distribute the time to the vehicle through the intersection keep straight on, control such as left-hand rotation; Though also can play certain mitigation; But inefficiency, serious day by day traffic congestion phenomenon is appointed so and can't be solved completely.

Building overpass bridge can address this problem, but the overpass bridge of now building in the intersection, two road is of a great variety; Complex structure is not if be very familiarly to be easy to go in the wrong direction this baroque overpass bridge to road conditions; Not only go to make easily and get lost; And its construction costs is expensive, and floor space is big, does not also have very desirable solution at present.

Summary of the invention

Goal of the invention:

The utility model provides a kind of overpass bridge, its objective is the existing problems of invention such as the grade separation bridge construction is complicated in the above-mentioned prior art, cost is high, floor space is big that solve.

Technical scheme:

A kind of overpass bridge, said overpass bridge are three layer construction, mainly are made up of lower floor's direct lane, rotary island track, ground and upper strata direct lane; Rotary island track, said ground is provided with on the ground, and the below in rotary island track, ground is lower floor's direct lane, and top, rotary island track, ground is the upper strata direct lane, and lower floor's direct lane is vertical with the upper strata direct lane.

On the bystander's row of channels of rotary island track, said ground, also set up overpass.

Said lower floor direct lane is set to east-west direction.

Said lower floor direct lane is set to North and South direction.

Advantage and effect:

The utility model provides a kind of overpass bridge, have following advantage:

(1), simple in structure.

(2), engineering quantity is little.

(3), cost is low.

(4), floor space is little.

Description of drawings:

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model structural representation;

Description of reference numerals:

1, lower floor's direct lane; 2, ground rotary island track; 3, upper strata direct lane; 4, walkway; 5, overpass.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is done further explanation:

The utility model provides a kind of overpass bridge, shown in Fig. 1, Fig. 2, it is characterized in that: described overpass bridge is divided into and is three layer construction, mainly is made up of lower floor's direct lane 1, rotary island track, ground 2 and upper strata direct lane 3; Rotary island track, said ground 2 just is provided with on the ground, below rotary island track, ground 2, is set to lower floor's direct lane 1, above rotary island track, ground 2, is set to upper strata direct lane 3, and lower floor's direct lane 1 is vertical with upper strata direct lane 3.

As shown in Figure 2, be provided with walkway 4, on walkway 4, also set up overpass 5, can supply the pedestrian to pass through on 2 next doors, rotary island track, described ground.

Said lower floor direct lane 1 can be set to east-west direction.

Said lower floor direct lane 1 also can be set to North and South direction.Concrete direction can be provided with according to the requirement or the situation such as geologic structure and neighboring buildings of practice of construction.

This overpass bridge of the utility model; Below reaching above the rotary island track, ground 2, direct lane is set; During use; Realize that through rotary island track, ground 2 plane of vehicle turns to, through vehicles directly passes through the crossing through upper strata direct lane 1 or lower floor's direct lane 3, and turning vehicle can be regulated through rotary island track, ground 2 travel directions.

The utlity model has advantages such as simple in structure, that engineering quantity is little, cost is low, floor space is little, be suitable for applying.
