Description
Technical field
The present invention relates to more river engineering and cross over the road interchange general arrangement field on (or passing through) Binjiang (river) road (relating to " river (river) " place below all referred to as " river "), is a kind of general layout design scheme of interchange specifically.
Background technology
Along with the sustained and rapid development of Chinese society economy and urbanization process, motor vehicle constantly increases, and road traffic is also in the process increased fast.Because the scope in city, various places constantly expands, the development range in many cities breaches the obstruct of rivers, brings the growth that river transport need is got in city.
The more river project of urban road has bridge and two kinds, tunnel.Navigation requires that its under-clearance height of high rivers is higher, and this situation makes circuit when getting over river, requires that bridge is so that higher height to stride across rivers; Or due to the bottom of rivers comparatively dark, require tunnel with under the darker degree of depth through rivers.No matter adopt the form in bridge or tunnel, all usually can be difficult to the Binjiang Road at grade intersection with parallel rivers, and on having to across or under wear Binjiang Road situation occur.Also have a kind of situation to be that often flood control standard is higher for city rivers, bridge must be crossed over along the higher flood wall of river bank or flood-control wall, also make bridge cannot with Binjiang Road at grade intersection, and have to take clover leaf form.In addition, the usual Lijiang River, Binjiang Road plotted line position bank is comparatively near, and more the road in river is also often important road, the traffic volume also can be larger, also do not wish and Binjiang Road at grade intersection, because vehicle may be made like that to block up in a large number in bridge or tunnel, when having an accident, process is more difficult; Further, vehicle block up in tunnel produce waste gas to tunnel environment and tunnel face environment also very unfavorable.
Urban Binjiang Road is usually road important in city, for such Binjiang Road, more in the engineering of river across or under wear Binjiang Road time, also to require and Binjiang Road can be sensible mutually.The urban three-dimensional crossroad form built up both at home and abroad is a lot, has directional interchange, clover leaf interchange, diamond interchange, rotary interchange, trumpet interchange, combined crossover etc.The grade separation of these forms is used in when Binjiang Road intersects Railway Project, and one is that occupation of land is large, building removal is many, cost is high; Two is need the river surface part getting over Jiang Qiaoliang or tunnel just to carry out bifurcated, add the difficulty that in water, bridge pier or tunnel are implemented, this may bring following problem: 1) affect flood passage safety, 2) the facade effect of bridge in water surface part is affected, 3) wagon flow blocks up on the main channel in bridge or tunnel.
Analyze the graded crossing of more river engineering and Binjiang Road, according to the regulation of " urban road engineering design specifications " (CJJ 37-2012) and " urban road intersection design discipline " (CJJ 152-2010), according to the difference of two road grade and traffic character, there are three kinds of forms: i.e. hinge interchange, general interchange, grade separation without ramps.Wherein, hinge interchange is applicable to more river engineering and Binjiang Road is all the condition of city expressway; It is junior road that grade separation without ramps is applicable to Binjiang Road, and as branch road or secondary trunk road, or function analysis is without the graded crossing of intercommunication demand; General interchange is applicable to the condition that Binjiang Road is arterial road, and when road network condition needs, Binjiang Road also can adopt the pattern of general interchange as secondary trunk road.
As general interchange, main traffic flows to and will ensure that secondary traffic direction allows the impact intersected not by cross influence, and namely secondary traffic flow can at grade intersection, as long as level-crossing can bear these traffic volume.In the intersection of getting over river engineering and Binjiang Road, more the traffic flow in engineering direction, river flows mostly to, and more river construction investment is large on the one hand, the more river engineering finite in a city, mostly build on major road, the traffic volume is also often comparatively large, and the traffic support degree of requirement is higher; On the other hand, Binjiang Road is often close to the water front of great rivers, and more river engineering logs in and flushed not as good as adjustment elevation and Binjiang Road afterwards; Therefore reasonably processing method strides across Binjiang Road in the lump when bridge strides across rivers, or tunnel passes Binjiang Road in the lump through during rivers, to make the wagon flow in more engineering direction, river by the impact of at grade intersection.Problem is in these cases, and how reaching the sensible mutually of two road traffic flow, is urgent problem.
The scheme that the general interchange of usual use solves intercommunication problem is not ideal enough.As full alfalfa leaf type grade separation (see figure 10), not only take up an area large, also need to go out to turn right ring road from river surface upper bifurcation, may affect the traffic of river surface Duan Yuejiang engineering main channel, also may get over river engineering in river surface section is Large Span Bridges, or shield tunnel, structure is difficult to bifurcated, also there is certain restriction water conservancy aspect, and pedestrian and non motorized vehicle is crossed intersection and had some setbacks very much, detours more.Semi-directional combined crossover (see Figure 11), rotary interchange (see Figure 12) or all or part have such problem.
Winding type grade separation (see Figure 13), although take up an area less, roundabout ring road interweaves serious, will affect the traffic capacity of grade separation, and the shunting of wagon flow of turning right needs at river surface section bifurcated, also larger on the impact of getting over engineering main channel, river.Diamond interchange (see Figure 14) is the very succinct scheme of general interchange, takes up an area less, reduced investment, Main way through-traffic stream strides across (or under through) intersection, and other traffic flows pass crosswise in intersection, ground.Problem does not generally wish that the river surface section bifurcated getting over river engineering goes out ring road, therefore just can not directly adopt the scheme of diamond interchange to solve the problem of Binjiang Road grade separation.
In sum, the problem to be solved in the present invention is:
1, more river engineering should stride across or under through Binjiang Road (namely more river engineering craspedodrome wagon flow should with the graded crossing of Binjiang Road wagon flow), more river engineering turning wagon flow can be sensible mutually with Binjiang Road, and bicycle and pedestrian can conveniently by intersections;
2, more river engineering can not at river surface section bifurcated ring road;
3, the Binjiang Road level-crossing traffic capacity should meet the demands;
4, scheme answers magnitude control, saves cost.

In technical indicator of the present invention, relate to plane index (circular curve, easement curve, widen, superelevation, acceleration and deceleration track and changeover portion, sighting distance), longitudinal section index (longitudinal gradient and length of grade section, vertical curve), cross section index (lane width, street medians width, marginal strip width, safety belt width) be all according to the requirement of design specifications.
The preferred embodiment (this example not as the restriction to embodiment of the present invention, during relevant condition change can by the corresponding adjusted design of code requirement) of the present invention's crossing-fiver bridge and Binjiang Road overpass area is below provided.Coordinate Fig. 1, (containing Fig. 2 a ~ Fig. 2 d, increasing sharp radius curve place is that the inner side meeting line-of-sight requirement increases width) shown in Figure 2, the more river engineering in this example is crossing-fiver bridge 30, (A-A place is access bridge cross section, shown with median strip and motorway to arrange two-way 6 motorways; B-B place is cross section of leading the way, the curb shown with median strip, motorway and both sides of leading the way).Binjiang Road 20 is two-way 8 motorways, design speed 60km/h; Both sides arrange nonmotorized vehicle lane and sidewalk (C-C place is the cross section of Binjiang Road, takes up from central strip, and side is followed successively by motorway, band, bypass, sidewalk are divided in side, and opposite side is as the same) respectively.Ring road is unidirectional 2 motorways, and design speed 30km/h(D-D place is the cross section of ring road).
Coordinate see shown in Fig. 1, Fig. 3, the southern bank in riverine (river) 10 of the Binjiang Road 20 in this example is arranged, and is separated by flood wall 40 and river (river) 10.Bridge 30 is shown in Fig. 3 from leap river, top (river) 10, flood wall 40, Binjiang Road 20(), form graded crossing 21 with Binjiang Road 20; The main line 31 of axle casing 30 continue to extend by original south-north direction, and in the both sides of main line 31, ring road is set respectively.
Wherein, the first ring road 51 connects the ring road of crossing-fiver bridge 30 for ground, and this first ring road 51 entrance and Binjiang Road 20 form the below of traffic interchange 21 or the outside of below that this level-crossing 22 of level-crossing 22(is positioned at bridge 30 and Binjiang Road 20); First ring road 51 is from described level-crossing 22 place, first in outside, first side (west side) of bridge 30, first end (southward) along this first side direction bridge 30 extends, reverse end for end after striding across bridge 30 main line 31, change in outside, second side (east side) of bridge 30, the second end (toward north) along this second side direction bridge 30 extends, until the first ring road 51 be in bridge 30 second side, the track of access bridge ragged edge is connected.
Suppose that Binjiang Road 20 is in the first height (being ground location substantially), access bridge to the main line 31 of crossing-fiver bridge 30 is in the second height (the second height is higher than the first height); The first then described ring road 51, it is in the first height when the level-crossing 22 with Binjiang Road 20, gradually raise until roundabout tune time be in third high degree thus cross over bridge 30 main line 31(third high degree higher than second height), then drop to gradually second height to be connected with the track of bridge 30.
Second ring road 52 is the ring road of crossing-fiver bridge 30 ground plane, the entrance of this second ring road 52 separates with main line 31 from the track of bridge 30 first side (west side), access bridge ragged edge, first outside the first side of bridge 30, first end (southward) along this first side direction bridge 30 extends, reverse end for end after striding across bridge 30 main line 31, change in outside, second side (east side) of bridge 30, the second end (toward north) along this second side direction bridge 30 extends, until the second ring road 52 is communicated with Binjiang Road 20 and forms level-crossing 23 with Binjiang Road 20.
The second described ring road 52, it is by from being in basically identical second height with bridge 30 during bridge 30 main line 31 bifurcated, be increased to gradually the 4th height thus cross over bridge 30 main line 31(the 4th height higher than second height, 4th highly can be identical or different with third high degree), then drop to the first height gradually and to be communicated with the level-crossing 23 of Binjiang Road 20.
The first auxiliary road 61 and the second auxiliary road 62 is also provided with in this example.Wherein, the entrance in the first auxiliary road 61 and Binjiang Road 20 form at grade intersection (as level-crossing 22), from this level-crossing 22 place, first auxiliary road 61 is in outside, first side (west side) of bridge 30, first end (southward) along this first side direction bridge 30 extends, until make the first auxiliary road 61 be connected with the track of bridge 30 first side main line 31 southern extension ragged edge.The entrance in the second auxiliary road 62, then separate from the track of bridge 30 second side (east side) main line 31 southern extension ragged edge, this second auxiliary road 62 is outside the second side of bridge 30, the second end (toward north) along this second side direction bridge 30 extends, until make the second auxiliary road 62 be communicated with Binjiang Road 20 form at grade intersection (as level-crossing 23).
Under different applicable cases, suppose that the southern extension of bridge 30 main line 31 is still in the second height, then the first first auxiliary road 61 is increased to second highly gradually from first to be highly connected with bridge 30, and the second auxiliary road 62 is reduced to the first height gradually after highly separating with bridge 30 from second and is communicated with traffic interchange.Suppose again, the southern extension of bridge 30 is finally reduced to the first height and is communicated with ground level road, then the auxiliary road of the second first 61 and the second auxiliary road 62 can be the ground level road being in the first height all the time respectively.
In this example, the first ring road 51 is with the roundabout tune of the inner ring of a small radii, and the second ring road 52 is in the outside of the first ring road 51, with the roundabout tune of the outer shroud of a relatively large radius; Further, the second ring road 52 once also formed graded crossing with it higher than the first ring road 51.First auxiliary road 61 is positioned at outside the first ring road 51 before tune, is also positioned at outside the second ring road 52 before tune.Second 62, auxiliary road is positioned at outside the second ring road 52 after tune, is also positioned at outside the first ring road 51 after tune.But these features described in this section can do corresponding modify according to concrete road conditions.
Coordinate see shown in Fig. 4, Fig. 5, Fig. 6, the vehicle that on Binjiang Road 20, first sidecar road (west is track eastwards) travels, can turn right below bridge 30 with the traffic interchange 21 of Binjiang Road 20; And the vehicle that on Binjiang Road 20, Second Edge track (the western track of east orientation) travels, can turn left below bridge 30 with the traffic interchange 21 of Binjiang Road 20.The aforementioned vehicle turning left from Binjiang Road 20 or turn right and come, after the roundabout tune of the first ring road 51, enter bridge 30 second track, side (track, south orientation north) thus be across to opposite bank, river (river) 10, or enter bridge 30 first track, side (track, north orientation south) to continue to travel in extension southward through the first auxiliary road 61, or continue to travel southwards along ground level road (this ground level road can be the outside being positioned at below bridge 30 or being positioned at the first the first auxiliary road 61, or this ground level road is exactly the auxiliary road 61 of the second first being positioned at ground all the time).The vehicle originally kept straight in Binjiang Road 20 first sidecar road or Second Edge track still keeps keeping straight on, keep straight on below bridge 30 through bridge 30 and the graded crossing of Binjiang Road 20 through.
Crossing-fiver bridge 30 is sailed the vehicle come from opposite bank (northern bank), can continue to travel southward along bridge 30 main line 31, or can travel to level-crossing 23 place with Binjiang Road 20 after the roundabout tune of the second ring road 52, turn left or turn right to enter Binjiang Road 20; And from southern extension along the vehicle that bridge 30 second skidding is sailed on bridge 30, can continue to travel along bridge 30 main line 31 toward north to be across to opposite bank, river (river) 10, or the second auxiliary road 62 being introduced into bifurcated in advance travels to the level-crossing 23 with Binjiang Road 20; (this ground level road is such as be positioned at below bridge 30 or be positioned at outside the first second auxiliary road 62 to ground level road, or this ground level road is the auxiliary road 62 of the second second being positioned at ground all the time) vehicle that northwards travels, also wheeled is to the level-crossing with Binjiang Road 20.Aforementioned various traveling, to the vehicle with level-crossing 23 place of Binjiang Road 20, can be turned right and enter Binjiang Road 20 first sidecar road (west is track eastwards), or turns left to enter Binjiang Road 20 Second Edge track (the western track of east orientation).
