Description

A kind of unlimited overpass bridge

Technical field

The utility model belongs to field of traffic facilities, relates to road overpass bridge with one voice, is specifically related to a kind of unlimited overpass bridge.

Background technology

Existing two-way lane road is overpass bridge with one voice, and the situation of intersecting according to road has a variety of settings.Comprise vertical track layer like common overpass bridge, horizontal track and turning roadway layer, setting is elsewhere separated in the track with the sidewalk; Wherein vertically the track layer adopts craspedodrome, and laterally track and turning roadway adopt rotating disk, though to reason vehicle, walk with one voice certain facility is provided; But exist the horizontal track of rotating disc type, the rotating disc type turning roadway still has a large amount of vehicle intersections; Pedestrian and vehicle intersection, people's car is current limited, treats that line time is longer; Along with the city vehicle pedestrian increases, show road day by day and block up with one voice seriously.

Summary of the invention

The inventor is in trip activity for many years; The road of the finding existing city two-way lane setting of overpass bridge with one voice exists certain defective, people to further minimizing road with one voice the overpass bridge that blocks up of traffic still have and crave for, through constantly exploring; Improve repeatedly; Purpose is to provide a kind of unlimited overpass bridge, and it is not limited that traffic is passed through, and solves the current with one voice problem of blocking up of road better.

The technical scheme that the utility model is taked is a kind of unlimited overpass bridge of design, and its structure comprises: two-way vertical direct lane layer of overpass bridge, directional transverse direct lane layer; Turning roadway layer and sidewalk; Wherein, two-way vertical direct lane layer and vertical right-turn lane layer, vertically the left turn lane layer is arranged on the intermediate layer; Directional transverse direct lane layer is arranged on the superiors, and laterally the right-turn lane layer is arranged on orlop with horizontal left turn lane layer;

Before the bridge post is striden in first of vertical direct lane layer import, establish up gradient, after last of vertical direct lane layer outlet striden the bridge post, gug is set; The import of vertical right-turn lane layer is arranged on the right side behind vertical direct lane layer up gradient; Through right-hand rotation garage descending overline bridge; Outlet is connected with the outlet left side of horizontal direct lane layer; The import of vertical left turn lane layer is arranged on the left side behind vertical direct lane layer up gradient, and through the left-hand rotation overline bridge, outlet is connected with the outlet left side of horizontal direct lane layer;

After the bridge post is striden in first of horizontal direct lane layer import, establish up gradient, after last of horizontal direct lane layer outlet striden the bridge post, set the ramp;

Laterally the import of right-turn lane layer is arranged on the left side of horizontal direct lane layer import; Through overpass bridge orlop right-turn lane; Outlet is connected with the outlet left side of vertical direct lane layer; Laterally the import of left turn lane layer is arranged on the left side of horizontal direct lane layer import, and through overpass bridge orlop left turn lane, outlet is connected with the outlet left side of vertical direct lane layer;

The consistent isolation setting in each sidewalk with each track; Wherein vertically keep straight on sidewalk and vertical right-hand bend descending overline bridge confluce through the pedestrian overcrossing grade separation; Vertically the import of left-hand rotation sidewalk is provided with vertically the left turn lane is consistent through the upward slope pedestrian overcrossing; Outlet is through descending pedestrian overcrossing and vertical right-turn lane grade separation, and sidewalk and horizontal right-turn lane grade separation laterally turn left.

The utility model adopts technique scheme and measure, to existing road with one voice overpass bridge improve, vertically the track, laterally direct lane is all adopted in the track; Direct lane and turning roadway divide three layers of setting, and the sidewalk is consistent with the track to isolate setting, has not only reduced overpass bridge at road occupied ground with one voice; Improved the space utilization degree; Can utilize the original place construction of road overpass bridge, save the engineering quantity of widening, remove, and traffic lights have all been saved on vertical track, horizontal track, vertical left turn lane, vertical right-turn lane, horizontal right-turn lane, horizontal left turn lane and sidewalk; Vehicle, pedestrian are limited through not treating line time; Form unlimited overpass bridge, improved the road traffic capacity with one voice widely, avoided jam.

The specific embodiment

In conjunction with accompanying drawing and embodiment, further specify the concrete structure of the utility model.

The embodiment of a kind of unlimited overpass bridge of the utility model, referring to Fig. 1, its structure comprises: the two-way direct lane layer of overpass bridge; Directional transverse direct lane layer, turning roadway layer, sidewalk; Wherein, Two-way vertical direct lane layer and vertical right-turn lane layer, vertical left turn lane layer are arranged on the intermediate layer, and the directional transverse direct lane is arranged on the superiors, and laterally the right-turn lane layer is arranged on ground floor with horizontal left turn lane layer;

Before the bridge post is striden in first of vertical direct lane layer import 1, establish up gradient 2, after last of vertical direct lane layer outlet 11 striden the bridge post, descending 10 is set; The import of vertical right-turn lane layer is arranged on the right side behind vertical direct lane layer up gradient 2; Through right-hand rotation descending overline bridge 4; Outlet is connected with outlet 6 left sides of horizontal direct lane layer; The import of vertical left-hand bend layer is arranged on the left side behind vertical direct lane layer up gradient 2, and through left-hand rotation overline bridge 14, outlet is connected with the outlet 13 of horizontal direct lane layer;

After the bridge post is striden in first of the import 7 of horizontal direct lane layer, establish up gradient 9, after last of horizontal direct lane layer outlet 13 striden the bridge post, set ramp 12;

The bend to right import 8 of track layer of mould is arranged on the left side of horizontal direct lane layer import 7; Ground right-turn lane (not shown) under overpass bridge; Outlet is connected with outlet 11 left sides of vertical direct lane layer; Laterally the import 8 of left turn lane layer is arranged on the left side of horizontal direct lane import 7, ground left turn lane (not shown) under overpass bridge, and outlet is connected with outlet 16 left sides of vertical direct lane layer;

The consistent isolation setting in each sidewalk with each track; The sidewalk of wherein vertically keeping straight on is provided with pedestrian overcrossing 3 grade separations with vertical right-hand bend descending overline bridge 4 confluces; Vertically the left-hand rotation sidewalk is through upward slope overline bridge 15 and vertically left turn lane 14 consistent settings; Outlet is through descending pedestrian overcrossing and vertical right-turn lane 4 grade separations, and sidewalk and horizontal right-turn lane 4 grade separations laterally turn left.

This unlimited overpass bridge of the utility model is applicable to that two-way bicycle road, two-way multi lane roadway use with one voice, is particularly suitable for the old city road and transforms use with one voice.
