Description
Technical field
The utility model relates to two layers of full interchange viaduct design scheme of a kind of crossroads, belongs to the traffic design field.
Background technology
Big of the traffic bottlenecks of urban road network concentrate on level-crossing; According to the related data statistics, when motor vehicle went on the urban road, average 1/3 time was used on the level-crossing; 64% traffic accident occurs in crossing, and the traffic capacity generally reduces by 46%～50%.In order to improve the traffic capacity of intersection; Often adopt and widen the mode of entrance driveway, but in the urban road, often receive the restriction of neighboring buildings; Cost and the cost of widening the crossing inlet road are often very big, and these all are the insoluble difficult problems in surface road intersection.In order to solve urban traffic blocking, the grade separationization of intersection receives people's attention day by day.Graded crossing can separate traffic conflict point from different aspects; Be to solve level-crossing traffic conflict problem method the most completely; Therefore many people propose to utilize graded crossing to replace the serious level-crossing of congested problem, solve the urban traffic congestion problem with this.Graded crossing can realize, craspedodrome shunting spatially, improves the traffic capacity of crossing, reduces the delay rate of crossing's vehicle, reduces the generation of traffic accident.
The cross graded crossing is according to the difference of the mode that the left-hand bend vehicle is handled, the combination shape grade separation that roughly can be divided into directional type complete intercommunicating overpass, cloverleaf interchange, annular interchange and above-mentioned three kinds of left-hand bend vehicle processing modes are combined.
Directional type complete intercommunicating overpass (referring to Fig. 1) is that all directions vehicle all goes on directly current special-purpose ring road, and travel route is simple and direct, convenient, safety, and the traffic capacity is big.But the ring road number of plies of this kind grade separation is many, takes up an area of greatly, and engineering structures is complicated, and is costly, generally is applicable to the intersection that all directions vehicle flowrate is all bigger.According to the actual conditions of traffic, also can make the graded crossing of part directional type, promptly only directed ring road is set in the major flow direction.
Cloverleaf interchange (referring to Fig. 2) is the typical style of interchange.It is provided with 270 ° of circular ring roads in four quadrants around the intersection, use for left turning vehicle, turns left not turn left, and but oppositely turning right continuous 270 ° reaches the left-hand rotation purpose, all directly is communicated with outside ring road and turn right.This grade separation has been eliminated all conflict points, and only need build a bridge block, and the traffic capacity is big, is applicable to the decussation mouth that land used is sufficient, all directions vehicle flowrate is all very big.But it takes up an area of big, and cost is higher, is limited to save the area, and circular ring road radius can not be too big.
Annular interchange (referring to Fig. 3) is to realize the grade separation mode that all directions are turned through a circuit.With stride on the major road or under wear circuit directly through the intersection, unimpeded to guarantee the major road straight-going traffic, and other vehicles all along circuit by counterclockwise detouring, and the crossing direction of selecting to be gone is rolled away from.The traffic capacity of rotary interchange receives the restriction of the circuit section of the interweaving traffic capacity; When turning to wagon flow big, often cause traffic congestion easily; And road speed depends on the size of circuit radius, when the circuit radius is excessive, exists equally at urban inner and takes up an area of excessive shortcoming.
The utility model content
The purpose of the utility model provides two layers of full interchange viaduct of a kind of crossroads; Thoroughly the solution directional type complete intercommunicating overpass ring road number of plies is many, occupation of land is big, engineering structures is complicated, costly; Its occupation of land of cloverleaf interchange is big, the cost traffic capacity higher, left turning vehicle is limited by circular ring road radius; The annular interchange takes up an area of problems such as restriction big, that the traffic capacity receives the circuit section of the interweaving traffic capacity; It only utilizes the shared land area of conventional cross level-crossing; Build two layers overpass bridge, just can the traffic conflict of motor vehicle wagon flow be separated in space aspects fully, realize that all turn to wagon flow passing through continuously on time and space.
The utility model is that the technical scheme that its technical problem of solution is adopted is,
Two layers of full interchange viaduct of crossroads include the horizontal arterial highway and vertical arterial highway that are positioned at ground floor, and laterally the arterial highway is intersected in the staggered portion of cross with vertical arterial highway, it is characterized in that,
Said horizontal arterial highway has two-way direct lane, and the staggered portion of said cross is provided with down wears the tunnel, and said two-way direct lane is through wearing tunnel holing through under this, and said vertical arterial highway is provided with the craspedodrome viaduct, and the craspedodrome viaduct strides across the cross road surface vertical arterial highway is communicated with;
Vertically the arterial highway also is provided with the left-hand rotation viaduct, and the left-hand rotation viaduct strides across the cross road surface and is connected with horizontal arterial highway, and laterally the arterial highway is provided with left turn lane, and left turn lane passes through from the staggered portion of cross, is communicated with vertical arterial highway;
Laterally the both sides of arterial highway and vertical arterial highway are equipped with right-turn lane, and adjacent right-turn lane is communicated with at the staggered portion of cross edge.
Said craspedodrome viaduct is provided with two; Two craspedodrome viaduct current in the opposite direction; Said left-hand rotation viaduct is provided with two; Two left-hand rotation viaduct current in the opposite direction, said left-hand rotation viaduct is lighted the slope together and is kept same absolute altitude with craspedodrome viaduct in the same way, walks around this craspedodrome viaduct at the ground connection place of the craspedodrome viaduct of subtend and also curves left with horizontal arterial highway and be communicated with.
The advantage of the utility model is; This overpass bridge only utilizes the shared land area of conventional cross level-crossing; Build two layers overpass bridge, just can the traffic conflict of motor vehicle wagon flow be separated in space aspects fully, realize that all turn to wagon flow passing through continuously on time and space;
The craspedodrome wagon flow of its major road adopts the bridge crossing form to stride across road intersection; The craspedodrome wagon flow bridge crossing of uplink and downlink direction is taked the asymmetric design scheme; Be that uplink and downlink direction craspedodrome wagon flow bridge crossing strides across behind the road intersection ground connection immediately; And be not the same with common grade separation, the slope point that rises of uplink and downlink direction craspedodrome wagon flow bridge crossing is consistent with earth point;
The left turn traffic bridge crossing of major road and craspedodrome wagon flow bridge crossing in the same way play the slope simultaneously and keep same absolute altitude, stride across subtend craspedodrome wagon flow at the ground connection place of subtend craspedodrome wagon flow bridge crossing and accomplish;
The left turn traffic of road intersection and all right-hand rotation wagon flows are accomplished through ground floor and are turned to, and the craspedodrome wagon flow of road intersection adopts the underpass type tunnel style to pass through the intersection.Hour also can cancel the underpass type tunnel of craspedodrome wagon flow when the road intersection vehicle flowrate, craspedodrome wagon flow and left turn traffic pass through the intersection at ground floor employing control mode signal.
