Abstract

The invention relates to an unblocked cloverleaf intersection at a traffic crossroad. Two layers or more than two layers of roadways are built at the crossroad, wherein the first layer of pavements are distributed on the most bottom surface of the crossroads in a cross manner; the middle of a road in a straight direction is provided with a pavement A at the first layer for vehicles to go straight; are pavements A1 and A2 at the second layer are arranged at the left side and the right side of the pavement A at the first layer; the center of the crossroads is provided with a ring-shaped viaduct; a pavement B at the first layer is arranged at the most bottom layer in the vertical direction of the pavement A at first layer; the middle of the pavement B at the first layer is provided with a pavement at the third layer; pavements B1 and B2 at the second layer are arranged at the left side and the right side of the pavement at the third layer; and a curved rod communicating the pavements B1 and B2 at the second layer is arranged between the pavements B1 and B2 at the second layer. The invention enables the vehicles to run on own roads, so the condition of cross running can not happen, thereby increasing the traffic flow of the current roads and reducing and even avoiding fuel air pollution created by the vehicles due to waiting for pass.

Description

Unblocked cloverleaf intersection at traffic crossroad
Technical field:
The present invention relates to a kind of unblocked cloverleaf intersection at traffic crossroad.
Background technology:
The modern city traffic relies on traffic lights transport solution problem, the effect of traffic lights is exactly to adopt the mode of blocking up, letting out to solve the increasing magnitude of traffic flow, but this mode is when the magnitude of traffic flow acquires a certain degree, as: in the peak on and off duty time, just highlight its drawback, even the traffic police appears to coordinate to dredge, still cause the phenomenon of blocking up.China is a populous nation, and along with improving constantly of living standards of the people, car owning amount constantly increases per capita, and the phenomenon of traffic congestion is more and more serious.The traffic problems of crossroad have become traffic police department serious problems anxious to be solved.
Summary of the invention
The object of the present invention is to provide a kind ofly under the situation that does not need traffic lights, can solve crossroad access block up problem and the rational unblocked cloverleaf intersection at traffic crossroad of road design.
Technical scheme of the present invention is as follows: the road surface that two layers or more is set at the place, crossroad of road; The first floor road surface is crossing distribution bottom surface at the parting of the ways, and the road surface is the wideest; Be provided with direct lane as the motor vehicle on first floor A road surface in the middle of the road of a craspedodrome direction; On the right side on first floor A road surface is second layer A1 road surface, is the bend of turning left or turn right as the vehicle that is come by this direction running; The initiating terminal on second layer A1 road surface is positioned on the first floor A road surface, initiating terminal from second layer A road surface, center position along the crossroad, improve gradually on its road surface, the end on second layer A1 road surface is connected with the annular viaduct of center, crossroad and is on the sustained height, and peaks; The center is provided with belt viaduct at the parting of the ways.In the left side of this direct lane is second layer A2 road surface, it is the vehicle pass-through road that comes as by other three direction runnings, its structure and second layer A1 road surface are identical, and form the autos only road of the both sides that are symmetrically distributed in first floor A road surface with second layer A1 road surface; Be current bicycle or pedestrian's road on the first floor road surface in the outside on second layer A1 and A2 road surface; Two opposite side (that is: along the axis of annular viaduct, second layer A1 and A2 road surface are symmetrical distribution) that second layer A1 and A2 road surface are symmetrically distributed in the crossroad respectively along the warp or the parallel of crossroad.
The bottom on the vertical direction on first floor A road surface is first floor B road surface, first floor A road surface and first floor B road surface are positioned on the same horizontal plane, so be referred to as the first floor road surface, they locate to intersect at the parting of the ways, are provided with the 3rd layer of road surface in the middle on first floor B road surface.
The initiating terminal on the 3rd layer of road surface drops on the first floor B road surface, raise gradually on center position, its road surface along the crossroad, the annular viaduct that the end on the 3rd layer of road surface and center, crossroad are provided with connects as one and is on the sustained height, and the 3rd layer of road surface is the craspedodrome passage as the vehicle that travels in the direction.The end on the 3rd layer of road surface is the road surface peak.
Be provided with second layer B1 road surface on the right side on the 3rd layer of road surface, second layer B1 road surface is curved the travelling of turning left or turn right as the vehicle that is come by this direction running; The initiating terminal on second layer B1 road surface is positioned on the first floor B road surface, initiating terminal from second layer B1 road surface, along the center position of crossroad, improve gradually on its road surface, and the annular viaduct that the end on second layer B1 road surface and center, crossroad are provided with connects as one and is on the sustained height.The end on second layer B1 road surface is the road surface peak.
Be provided with road surface as second layer B2 in the left side on the 3rd layer of road surface, second layer B2 road surface can be used as by other three direction runnings and the vehicle pass-through road that comes, its structure and second layer B2 road surface are identical, and form the autos only road that is symmetrically distributed in both sides, the 3rd layer of B road surface with second layer B2 road surface.
Also be provided with the bend that is communicated with second layer B1 road surface and second layer B2 road surface on second layer B1 between the initiating terminal on second layer B1 and B2 road surface and annular viaduct and the B2 road surface, second layer B1 and B2 road surface be positioned at the 3rd layer about road surface both sides and be parallel to each other.Bend is positioned at the below on the 3rd layer of road surface, and the height between bend and the 3rd layer of road surface is enough to make vehicle pass-through.Two opposite side (that is: along the axis of annular viaduct, second layer B1 and B2 road surface are symmetrical distribution) that second layer B1 and B2 road surface are symmetrically distributed in the crossroad respectively along the warp or the parallel of crossroad.
The initiating terminal on second layer B road surface is than the more close crossroad of initiating terminal on the 3rd layer of road surface, is enough to make vehicle pass-through to guarantee the height between bend and the 3rd layer of road surface.
Be made as current bicycle or pedestrian's road in the outside on second layer B1 and B2 road surface.
The present invention compared with prior art can solve the traffic jam issue that travels and caused because of the intersection of vehicle in the crossroad, road design is reasonable, can guarantee respectively to take their own roads to the vehicle that travels, do not produce the situation of travelling of intersecting, thereby improved the vehicle flowrate of existing road, reduced and even avoid vehicle to pollute because of waiting as long for the current fuel-air that causes.The building construction of the present invention by adopting steelframe to combine with concrete can be that structure of the present invention is more rationally compact, and steadiness is stronger.
