Abstract

The utility model relates to a three-layer flyover for urban roads. The three-layer flyover is provided with an arch bridge and a tunnel, wherein the arch bridge is vertical to the tunnel and arranged above the tunnel; the arch bridge is provided with a streamline bending elongated bridge panel with a higher middle part and two lower ends; an elongated ground panel is connected between the two ends of the bridge panel; bridge railings are arranged on the two sides of bridge panel in the length direction respectively; supporting pillars are connected between the bridge panel and the ground panel; a strip-shaped groove with rectangular section is formed in the tunnel; a groove cover is covered on the notch of the groove; a supporting pillar is connected between the groove bottom and the groove cover of the groove; inclined plates connected with the notch in the length direction are arranged at the groove bottom on the two sides of the groove respectively; and an inlet and an outlet are formed on the notch and at the two ends of tunnel. The urban road three-layer flyover divides the cross intersection into three layers. The urban road three-layer flyover is provided with a vertical crossing lane for straightly-going motor vehicles passing smoothly; and the urban road three-layer flyover is provided with a rotary intersection on the ground and pedestrians, rickshaws and the motor vehicles can pass through the intersection on the ground in a roundabout mode, so that traffic jam at the intersection can be effectively relieved and the speed of passing through the intersection can be increased. The urban road three-layer flyover is simple in structure and route setting and has small occupied area.

Description

Three layers of overpass bridge of urban road

Technical field

The utility model relates to the overpass bridge of the right-angled intersection of a kind of urban road facility, particularly a kind of urban road.

Background technology

Have a large population in the city, vehicle is also a lot, at urban road because the current of a large amount of People's Bank of China and vehicle arranged, cause urban road very crowded, particularly at the right-angled intersection of urban road, right-angled intersection, there are the pedestrian and the vehicle of four direction to pass through, vehicle has the lower rickshaw of speed, the higher motor vehicle of speed is also arranged, the pedestrian, when rickshaw and motor vehicle pass through right-angled intersection, on same ground, has plenty of craspedodrome, have plenty of and turn around, have plenty of left-hand bend, have plenty of right-hand bend, for the needs pedestrian, rickshaw and motor vehicle enter again from four direction from four direction and select one and the right-angled intersection that goes out is the crowded key area of urban road, at right-angled intersection traffic congestion takes place often traffic accident also takes place often.In order to solve the traffic congestion of cross roads, can build overpass bridge at the right-angled intersection of urban road, overpass bridge can allow pedestrian, rickshaw and the motor vehicle of four direction pass through right-angled intersection on the different face in space, overpass bridge has solved pedestrian, rickshaw and motor vehicle effectively blocking up that right-angled intersection takes place, and has also avoided traffic accident.In the prior art, enter again from four direction from four direction and select one and the overpass bridge structure and the path that go out are provided with complicated in order to solve pedestrian, rickshaw and motor vehicle energy, when turning, change existing conventional driving rule on the ground, need indication and guiding, the area and the space that take are bigger, are not that very big right-angled intersection is difficult to build overpass bridge at old town inner area and space.

Summary of the invention

The purpose of this utility model is in order to overcome above-mentioned deficiency, proposes a kind of structure and path and is provided with simplyr, does not change existing conventional driving rule on the ground when turning, three layers of overpass bridge of urban road that area that takies and space are less.

The utility model is realized with the following method.

Three layers of overpass bridge of urban road have mutually perpendicular arch bridge and tunnel, arch bridge is above the tunnel, arch bridge has the strip bridge deck of the low streamlined bending in middle high two ends, be connected with strip ground panel between the two ends of bridge deck, two sides of bridge deck have bridge railing along its length respectively, be connected with support column between bridge deck and the ground panel, it is strip groove apart from shape that there is the cross section in the tunnel, the notch of groove is stamped the groove lid, be connected with support column between the bottom land of groove and the groove lid, the bottom land of groove both sides has the swash plate that links to each other with notch along its length respectively, and the two ends in tunnel have the import and export at notch respectively.

Be to be used to the track that allows the motor vehicle opposite travel at the bottom of arch bridge bridge deck of the present utility model and the tunnel groove, press actual needs, width at the bottom of arch bridge bridge deck and the tunnel groove can be the width with unidirectional single track, also can be the width with unidirectional double lane width.

During installation, the utility model is installed in the right-angled intersection of urban road, Yi Tiaolu along right-angled intersection is embedded under the road surface the tunnel, make the length direction in tunnel parallel with this road surface, the import and export at two ends, tunnel are on the road surface, can be equipped with in the import and export and hide above the import and export and three shed, arch bridge another road along right-angled intersection is placed on the road surface, make the top and ground one of arch bridge ground panel flat, at right-angled intersection, except arch bridge and tunnel that above-mentioned square crossing is settled, the track parallel with the length of tunnel direction arranged on the ground of both sides, tunnel, the ground track parallel with the arch bridge length direction arranged on the ground of arch bridge both sides, on the ground in the outside, track, ground zebra crossing is arranged, the road surface of right-angled intersection becomes the traffic circle.

During use, pedestrian, rickshaw and motor vehicle can enter right-angled intersection from four direction, the motor vehicle of keeping straight on can pass through right-angled intersection through the utility model, the pedestrian who keeps straight on, turns left or turn right can pass through right-angled intersection through zebra crossing, the rickshaw of keeping straight on, turn around, turn left or turning right can travel the traffic circle on the road surface, after distributing the motor vehicle of craspedodrome, the motor vehicle that turns around, turns left or turn right also is to travel in the traffic circle on the road surface.

After the utility model is installed in right-angled intersection, track and the track at the bottom of underground tunnel groove on the square on the ground arch bridge bridge deck are arranged, the motor vehicle of keeping straight on can pass through at the bottom of arch bridge bridge deck and tunnel groove swimmingly, the road surface of right-angled intersection becomes traffic circle, the pedestrian, rickshaw and other motor vehicle pass through right-angled intersection by roundabout ahead on the ground, right-angled intersection divides three layers, the pedestrian, rickshaw and motor vehicle take their own roads by, distribute the motor vehicle of craspedodrome in the motor vehicle that particularly travels on the ground, the obstruction of slow effectively knot motor vehicle the time by right-angled intersection, raising is by the speed of right-angled intersection, structure of the present utility model and path are provided with simpler, do not change existing conventional driving rule on the ground, the area and the space that take are less.

Below in conjunction with accompanying drawing, the utility model is further described.
