Abstract

Low- span-depth high-channel separation-crossing intercommunicated crossroad is the novel design of intercommunicated grade separation suitable for the urban people and vehicle travelling. By innovatively and optimally the positions of the special channels and ingeniously arranging the paths for people and vehicle travelling, the utility model simplifies the cross grade separation structure, shortens the occupied lands,, delivers complete function and is economical and environment-friendly. With the principle of economizing idea of breaking through the existing standard of the crossroad bridges and lowering the span-depth, the low-span depth-crossing channel crossing crossroad is designed, thus the ramps are shortened, the scale of the interchange bridge is reduced, the construction cost is saved and the applicable performance is enhanced as well as the energy consumed for climbing the grade by numerous passing vehicles is reduced and the environmental contamination caused by the waste gas is reduced. The utility model is applied at the flat-land ramp, thus resulting in that the intersections are simply communicated with each other. Particularly an intermediate steering channel is arranged in the middle of the road, thus which not only can avoid the conflict of changing lanes between the motor vehicles turning right and the non-motorized vehicle travelling straightly but also can result in that the intermediate steering channel becomes the temporary channel which the super-high vehicles casually run on. The utility mode has variable types and low engineering cost, has few effects on the landscape, is widely suitable for crossroad and can result in that the travelling people and vehicles moving in various directions go smoothly in their own ways.

Description

Separation of low-span and high-level aisles to cross the intersection

technical field

The utility model belongs to the improvement of a road intersection, in particular to a low-span and high-level channel separated and crossing an intercommunicating intersection.

technical background

The development of human economy and technology makes automobiles more and more involved in social production and life, which brings busyness and congestion to urban road network traffic. In the prior art, urban road intersections also often adopt level intersections when the management of signal lights cannot adapt to the busy flow of people and vehicles. Existing level intersections are provided with individual constructions for pedestrians or traffic, such as pedestrian crossing overpass tunnels and express arterial overpasses, etc., as well as pedestrian traffic A merged three-dimensional intersection. In urban areas, road intersections are densely packed with pedestrians and vehicles, but the existing pedestrian-vehicle interchanges are usually erected in multiple layers and connected to multiple elevated ramps, which not only have a huge volume, engineering and cost, but also make pedestrians and vehicles difficult. It is cumbersome and inconvenient, so although there is a demand for bustling and lively road intersections in cities, it is difficult to accommodate and rarely used. The Chinese patent "Straight-Span and Level-Turn Urban Interchange" (200410067097.4; 200420090955.2) is designed and applied in combination with straight-through bridges and flat ramps to effectively simplify the three-dimensional intersection of roads. However, there are still more inconveniences and conflicts in the application of pedestrians crossing intersections in downtown areas. . The design and application of the Chinese patent "Short Slope Road Crossing Bridge with Low Auxiliary Span and Short Slope with Variable Main Span Height" (200610052571.5; 200620105865.5) breaks through the current road crossing bridge standard to reduce the clear span height, and opens up a road crossing bridge that greatly reduces the land occupation and saves costs. , A new way to greatly reduce the climbing consumption of passing vehicles and reduce exhaust pollution.

Contents of the invention

The purpose of this utility model is to provide a low-span and high-level passageway to separate and cross the intercommunication intersection. By innovatively optimizing the location of the special passageway and cleverly arranging the pedestrian driving path, the structure of the three-dimensional intersection is simplified and the footprint is reduced. And vehicles go their own way through reasonable and convenient crossing and turning passages to achieve orderly and smooth flow.

The purpose of this utility model is achieved like this: the low-span-high passage separates and crosses the intercommunication intersection, which is the longitudinal road of the cross road intersection to form sidewalks, pedestrian crossing passages, side turning passages, low-span and high crossing passages, middle turning passages, low High-span crossing passages, side turning passages, pedestrian crossing passages, and sidewalks are arranged in position; flat ramps surround buildings or green spaces inside corners of intersections to connect longitudinal roads and horizontal roads; low-span high-crossing passages and pedestrian crossing passages from underground, It is composed of sidewalks and roadways crossing intersecting transverse roads semi-underground or above ground. The pedestrian crossing passage is a pedestrian walking passage crossing the sidewalk and roadway of intersecting transverse roads from underground, semi-underground or above ground; The low-clear-span-height driving passage below the superelevation vehicle elevation of the road. The side turning channel is a driving channel located on the sidewalk side connecting the longitudinal road and the intersecting transverse road; the middle turning channel is located in the middle of the longitudinal road and is spaced between two low-span and high crossing channels to connect the longitudinal road and the intersecting transverse road The driveway on the level ground is the ground vehicle driveway that connects the longitudinal road and the transverse road around the inner building or green space at the corner of the intersection. At low-span-height passages crossing the intersection separately, straight pedestrians on the longitudinal road cross the horizontal road through the pedestrian crossing passage, straight-going motor vehicles and non-motor vehicles cross the transverse road through the low-span-height crossing passage, and right-turning motor vehicles turn through the middle Passage Non-motorized vehicles turn into the transverse road through the side turning passage. Motor vehicles and non-motorized vehicles that need to turn left first cross the transverse road through the low-span and high-crossing passage, and then detour through the flat ramp to change direction and enter the transverse road. On the transverse road, straight motor vehicles and non-motor vehicles can go straight without hindrance, right-turning motor vehicles pass through the middle turning channel, non-motor vehicles turn into the longitudinal road through the side turning channel, and left-turning motor vehicles and non-motor vehicles go straight across The longitudinal road changes direction and enters the longitudinal road through the level ground ramp detour. The low-span and high-level passage separates and crosses the interchange intersection to realize simple interchange traffic, but there are still some minor traffic conflicts between straight pedestrians and right-turning motor vehicles and non-motorized vehicles, as well as straight-going non-motorized vehicles and right-turning motor vehicles on the horizontal road. However, just as many branch road intersections and pedestrian crossings in urban roads do not need to set up traffic management, the vehicles and pedestrians crossing who have separated the special lanes, are sparsely scattered and are turning to slow down respectively adopt active avoidance and do not hinder the smooth flow at all.

The low-span and high-level passages are separated and crossed at the interworking intersections. Through innovation and optimization, the location of special passages is set up, and the pedestrian and vehicle paths are arranged ingeniously, so that the structure of the cross-level intersection is simplified, the footprint is reduced, and the functions are comprehensive, economical and environmentally friendly. It breaks through the current cross-road bridge standard to reduce the saving concept of clear span height, sets up low-span and high crossing passages to restrict the passage of super-high vehicles that are rare in urban areas, shortens ramps, reduces the size of interchanges, saves construction costs and improves applicability. The climbing energy consumption of countless passing vehicles is reduced, and the exhaust gas environmental pollution is reduced. It uses flat ramps to make the intersections easy to communicate with each other, and especially sets the middle turning channel in the middle of the road, which not only avoids the conflict between right-turning motor vehicles and straight-going non-motor vehicles, but also makes the middle turning channel a temporary place for occasional super-high vehicles. Passages to realize the smooth flow of pedestrians and vehicles in all directions.

Detailed ways

During the implementation of low-span and high-span passages crossing the intersections separately, underground, semi-underground or above-ground types can be selected according to the specific conditions of road intersections. The underground or semi-underground types have little impact on the environmental landscape, and shallow crossings are used to reduce the scale Generally canalized intersections can be accommodated. In urban areas where trucks are restricted from entering the city, low-span and high-level crossing passages can be set at the elevation that only urban buses can pass, so as to reduce the length of ramps and reduce the size of the overpass to reduce construction costs. If the non-motor vehicle and motor vehicle passages are separated or constructed separately, not only the span width of the motor vehicle passage can be reduced, but also the span height of the non-motor vehicle passage can be reduced to reduce the slope. During implementation, pedestrian crossing passages can be constructed in parallel or separately with low-span and high-crossing passages. Only two lanes should be provided in the middle turning passage to facilitate the driving of turning vehicles. Special vehicles and emergency vehicles pass or stop. The flat ramp is the ground traffic lane around the inner building or green space of the intersection corner by using the original or reconstructed new one. It can build the most ideal winding path at one time or several times according to the actual situation of the intersection. There may be no flat ramps on the inner side of the corner at that time or forever. This may be implemented by building as many ramps as possible. In special occasions, a section of the winding road can also be built underground, elevated or shielded to meet the landscape, function or environmental protection. requirements.
