Abstract

The invention relates to a rotating smooth type crossroad, comprising a cross right bridge. The cross right bridge is provided with four inner arc right hand bending channels; the four extending directions of the main artery on the cross right bridge are respectively provided with a left rotating channel which is an arc bending channel left rotating 360 degrees. The invention not only solves the vehicle smooth problem at the crossroad without red and green light control, but also has the advantages of simple structure, few layers, low height, short approaching bridge and investment saving, which is beneficial for popularizing and use.

Description

Yi Zhong rotation changes unblocked type crossroads

Technical field

What the present invention relates to is a kind of highway cross-over bridge, and particularly Yi Zhong rotation changes unblocked type crossroads.

Background technology

Along with social development, motor vehicles are in continuous increase, and the The coast is clear problem receives much attention, and the problem that particularly urban traffic is crowded day by day, the crossroad blocks up needs to be resolved hurrily.To the vehicular traffic of crossroad, generally take cross right bridge, individual layer rotary island formula viaduct etc., though these can improve the traffic of crossroad, also must use traffic lights control, traffic efficiency is very low.Occurred the direct interchange viaduct of a kind of full orientation afterwards, this overpass bridge can not established traffic lights, and vehicle can directly travel, solved the traffic problems of crossroad better, but this overpass bridge number of plies reaches four layers, access bridge is long, occupation of land is many, and investment is big, is difficult to popularize use.

Summary of the invention

The purpose of this invention is to provide that a kind of number of plies is few, cost is low, without the overpass bridge that can solve crossroad vehicular traffic retardance of traffic lights control.

The objective of the invention is to be achieved through the following technical solutions.

Yi Zhong rotation changes unblocked type crossroads, comprises the cross right bridge, has four arc right-hand bend passages on the cross right bridge, and respectively having a Ge Zuo rotation on four bearing of trends of cross right bridge major trunk roads changes passage.

The present invention has not only solved crossroad vehicle smooth problem, and traffic lights control no longer is set, and structure is simple and direct, the number of plies is few, highly low, access bridge short, reduced investment, be beneficial to promote the popularization use.

Wherein: 1 East and West direction major trunk roads, 2 north-south major trunk roads, 3-6 right-hand bend passage, 7 Zuo rotation change passage, and 8 adjacent Zuo rotation change passage.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is described in further detail.

With reference to Fig. 1, East and West direction major trunk roads 1 are the upper strata on the cross right bridge, and north-south major trunk roads 2 are lower floor on the cross right bridge, and two major trunk roads are two-way multilane.Between East and West direction major trunk roads 1 and north-south major trunk roads 2, on the four direction of cross right bridge near infall, have four arc right-hand bend passage 3-6 between two major trunk roads (the upper and lower), wherein: right-hand bend passage 3 and 5 is right-hand bend passages that north-south major trunk roads 2 (lower floor) lead to East and West direction major trunk roads 1 (upper strata); Right-hand bend passage 4 and 6 is right-hand bend passages that East and West direction major trunk roads 1 (upper strata) lead to north-south major trunk roads 2 (lower floor).

On four bearing of trends of cross right bridge two major trunk roads, respectively have an arc bend: Zuo rotation of 360 ° of turning left and change passage 7 (only show among the figure west to).

Changeing passage 7 with reference to Fig. 2, Fig. 3 ， Zuo rotation can be that as shown in Figure 1 level land Shi Zuo rotation changes passage; Also can change passage for overhead type and the left side of underground type as shown in Figure 3 rotation as shown in Figure 2; Can also change passage 8 with adjacent left rotation and build into double-deck bridge-type left side rotation commentaries on classics passage jointly.Described adjacent Zuo rotation changes passage 8, is meant that setting up this rotation of De in adjacent crossroad changes unblocked type crossroads De Zuo rotation commentaries on classics passage, as shown in Figure 1.

This rotation changes the cross right bridge in the unblocked type crossroads, can adopt the upper strata overhead system, also can adopt lower floor's tunnel formula, and can also adopt the upper strata is that partly overhead and lower floor is the combined type in half tunnel.East and West direction major trunk roads 1 and north-south major trunk roads 2 can be designed to two-way 6 tracks respectively.Four right-hand bend passage 3-6 between two major trunk roads generally can be designed to bicycle road or two-way traffic.Four Ge Zuo rotation change passage 7, are to be on four bearing of trends of cross right bridge two major trunk roads, are typically chosen in after the cross right bridge access bridge, to the appropriate location between another crossroad.The Zuo rotation changes passage 7, owing to can be designed to unidirectional bicycle road, so floor space is less, this is easier to relatively to the selection of its position.If all set up this overpass bridge in two adjacent crossroads, so left rotation changes passage 7 and adjacent left rotation changes passage 8, looks feelings and can build into double-deck bridge-type left side rotation commentaries on classics passage jointly, and floor space has just more been economized like this.

The route or travel by vehicle that this rotation changes unblocked type crossroads is exemplified below.

A, vehicle left-hand rotation vehicle line: with East and West direction major trunk roads 1, be example from east to south: vehicle strides across north-south major trunk roads 2 from the east orientation west along East and West direction major trunk roads 1 and travels, and arrives west side Zuo rotation and changes passage 7, after 360 ° of turnings, by right-hand bend passage 6, enter north-south major trunk roads 2 and travel southwards.By that analogy, vehicle is from south orientation west or westerly northwards or from the travelling of north orientation east, can be respectively left rotation by the north side left rotation that changes passage, the east side left rotation that changes passage, southern side change passage and travel.

B, vehicle right-hand rotation vehicle line: with north-south major trunk roads 2, be example in south to eastbound sailing: vehicle, enters East and West direction major trunk roads 1 and travels eastwards by right-hand bend passage 3 from south orientation north.By that analogy, vehicle can travel by right-hand bend passage 4,5,6 respectively from north east or from north west or from the travelling of west south.

Travelling in C, vehicle thing or north-south, can lead directly to travel on East and West direction major trunk roads 1 or north-south major trunk roads 2.

For the problem of sidewalk and cycleway, the architectural space that can utilize cross right bridge Huo Zuo rotation to change passage 7 is taken all factors into consideration solution, also can adopt overline bridge or underground passage to solve, and these all belong to routine techniques, repeat no more.

This rotation changes unblocked type crossroads, though do not belong to tall and big luxurious formula building, reduced investment can be improved the situation of current traffic congestion effectively, have very high should practical promotion price.
