The viaduct, urban district is to build built on stilts road above the intensive road of urban central zone wagon flow, is used for alleviating the Ground Vehicle flowing pressure or improves Vehicle Speed, has improved the path space utilization rate.Yet general viaduct overhead distance is larger, causes the ring road length of up and down bridge oversize, and not only addressing condition is harsh, and quantity is restricted, and the deficiency of ring road quantity easily causes up and down bridge mouth to block up.In addition, the column ground that is used for supporting the viaduct is darker, for the city that has flourishing lithic drainage, easily destroys the water channel of deep under ground.Because the cross-sectional area of column is little, excessive to below load-bearing rock pressure, so foundation settlement easily occurs, threaten road surface safety.Too high viaduct also can keep the sun off and the sight line of ground pedestrian, vehicle, has destroyed civic landscape.
Subway is that certain scale is arrived in urban development, for satisfy in the city, long demand apart from passenger traffic, alleviate the bus transport pressure and the railway communications and transportation mode opened.Most subways can be built in the tunnel below the urban road, yet such tunnel is often darker, for the city that has flourishing lithic drainage, easily destroys the water channel of deep under ground.Not only cost is higher to deep-cut in addition subway, and high ferro to build cost suitable, and the risk of surface collapse is arranged during building the tunnel, can cause serious consequence.Addressing in crowded urban district, build subway station and also be not easy, sometimes also will do a large amount of relocating works, extra increasing built difficulty.
Present highway tunnel mainly contains mountain tunnel, Chuan Jiang tunnel, seabed tunnel etc., and purpose is for passing through the natural obstacle thing, connect two side areas, facilitates two ends vehicle, personnel's dealing current.Nowadays tunneling technology mainly is confined to traditional shield structure technology, and its shortcoming and subway tunnel are similar, and the technology as the immersed tube tunnel of port Zhuhai and Macao bridge use is seldom arranged.The tunneling purpose also seldom has as the Bund in Shanghai tunnel alleviates traffic above-ground pressure, the protection civic landscape.
Summary of the invention
The technical problem to be solved in the present invention is the defects that how to overcome prior art, provides a kind of major urban arterial highway three-dimensional transportation system.
For solving the problems of the technologies described above, this major urban arterial highway three-dimensional transportation system comprises arterial highway and the branch road that intersects with the arterial highway, and the arterial highway comprises the viaduct and be positioned at the ground floor of below, viaduct, and ground floor has subway tunnel; The viaduct is provided with the column that supports the viaduct, three arranged side by side of column is one group, middle center stand column is goed deep into the soffit of subway tunnel and has been connected with the tunnel upper surface with the tunnel soffit being connected, the column on both sides and the sidewall of subway tunnel are connected as a single entity, till all columns all are deep into the tunnel soffit.
So design, column had both supported the viaduct, supported again ground floor, and all wt reaches the subway tunnel soffit, then reaches the below soil layer.Compare with the original high racks road, the column pile foundation can be too not dark, is not easy to destroy the water channel of deep under ground, is fit to the city of lithic drainage prosperity; And the subway tunnel soffit is large to the contact area of below soil layer, has reduced geostatic pressure, has effectively alleviated foundation settlement.
As optimization, the subway tunnel left and right sides is provided with left tunnel and right tunnel, and the three is the box culvert tunnel.The vehicle of both direction is passed through respectively, goes in so design, left tunnel and right tunnel, can bring into play the effect of alleviating traffic above-ground pressure, the more important thing is the utilization rate that has greatly improved original path space.
As optimization, at large-scale crossing, by underground interchange, left tunnel is connected with the ground branch road with right tunnel, underground interchange adopts elongated double-layer cross flower bridge, left tunnel and right tunnel are as lower floor, and branch road is as the upper strata, and underground interchange discrepancy ring road is parallel with branch road, enter left tunnel and right tunnel under oblique from branch road ground, current in dual-way vehicle.So design, if in left tunnel and right tunnel, vehicle wants turn right to arrive right branch, turn 90 degrees on the ring road right side recently and get final product, if want to turn left the arrival left branch, only need move ahead arrives right branch ground by next ring road 270 degree of turn-taking, then keeps straight on and arrive left branch by the crossing; Enter the tunnel, arterial highway if road vehicles is wanted to turn right, turn 90 degrees on the ring road right side recently and get final product, if want to turn left to enter the tunnel, arterial highway, only need move ahead by the crossing, turn-take at next ring road and 270 spend, effectively alleviate traffic above-ground pressure.
As optimization, at the intensive large-scale crossing of building, by arrange on the arterial highway turn left out ring road with turn left to enter ring road the arterial highway be connected with right tunnel with left tunnel; By being set on branch road, the ring road of turning right with the ring road of turning right out, branch road is connected with right tunnel with left tunnel; The ring road that turns left out upwards leads directly to the arterial highway ground floor from right left tunnel skew back, the ring road of turning right out is underground from right tunnel right hand steering branch road, then lead to obliquely ground floor, these two ring roads are the ring roads that the tunnel, be symmetrical in branch road and also have two ring roads that enter the tunnel, also there are four such discrepancy ring roads in left tunnel, near 8 discrepancy ring roads altogether each crossing.So design, if in right tunnel, vehicle wants turn right to arrive right branch, the ring road of selecting to turn right out recently directly arrives right branch ground, if want to turn left to arrive left branch, the ring road of selecting to turn left out recently arrives ground, trunk road, proceeds to junction ahead and turns left to arrive left branch again; Enter the tunnel, arterial highway if a road vehicles is wanted to turn right, select nearest right-hand rotation to enter ring road and directly enter the tunnel, if want to turn left to enter the tunnel, arterial highway, only need crossing left-hand rotation arrival arterial highway forwardly, proceed to into the ring road mouth down to the tunnel.
As optimization, below, box culvert tunnel is provided with underground two layers of pedestrian collecting and distributing space, and these underground two layers of pedestrian collecting and distributing spaces are rectangular, and the central area is subway safety check, charge, Transfer Hall, and place, branch road crossing is provided with access, underground two layers of collecting and distributing space of pedestrian; Be arranged with peripheral collecting and distributing passage outside underground two layers of pedestrian collecting and distributing space, the peripheral collecting and distributing passage outside can hew out certain area, and news-stand, Mini Supermarkets, public lavatory, all-purpose card recharge point, municipal project pay the fees handy service for the people facility and the projects such as point, train ticket Self-service Tickets are set.So design is compared with traditional pedestrian's street crossing tunnel, and this collecting and distributing space function is more, more convenience-for-people, and has repaiied in the lump when constructing road, need not extra planning, addressing, builds.
As optimization, the both sides, large-scale crossing that arterial highway and branch road intersect are provided with on the viaduct bridge ring road under bridge ring road and viaduct, come, go both direction that upper and lower two ring roads are respectively arranged, and symmetrical, establish altogether four ring roads around each crossing, every ring road is connected on the viaduct near the crossing end, connects ground floor away from the crossing end.So design, the vehicle on the arterial highway can arrive front upper viaduct, crossing, can reach viaduct at present after by the crossing on the viaduct, the time of crossing craspedodrome red light such as has saved; In addition, incorporate the viaduct inner lane into behind the viaduct on the vehicle of long distance travel, can avoid descending at once the viaduct; Owing to having passed through the crossing behind viaduct under vehicle, the front is a long section way, rather than the crossing of red light is arranged, so be not prone to the situation of lower overhead crossing congestion; Compare with original high racks road ring road, ring road quantity increases, and vehicle is selected more versatile and flexible, and has avoided being connected on the viaduct away from the crossing end, connects near the crossing end the lower overhead crossing congestion that cause on ground.
As optimization, ground floor central region between three root posts of viaduct, two bus zones are set, in the middle of two bus zones, near crossing place, the bus platform zone are set, column arranged outside greenbelt, greenbelt arranged outside buffering road, runway is established in the outside, buffering road, establishes stopway outside runway, the sidewalk is established in the stopway outside, and cycleway is established in the outside, sidewalk.So design, the buffering road provides the lane change space for the vehicle of viaduct, up and down.The vehicle that lane change enters the buffering road can directly lead to upper bridge ring road ground surface end, and vehicle lands the rear buffering road of directly entering from lower bridge ring road.In the place that ring road is set, due to highly not enough, the track no longer is set, but frees out below ring road, namely cushion the part and taken by the viaduct ring road; Compare with existing viaduct, this lane change cushion space will make vehicle viaduct, up and down more at leisure, particularly descend bridge vehicle needn't stand the crowded of road also; Secondly, compare with present most major trunk roads, arranging of stopway will effectively solve the present situation of temporary parking difficulty, the driver needn't worry can not find stop for vehicle trouble again, it is also convenient that the pedestrian takes taxi, and the vehicle that normally travels needn't worry that more the drop off the guests stop of vehicle of the place ahead makes own reduction of speed; In addition, be to facilitate the pedestrian to be parked in up and down the vehicle of dropping off the guests of stopway with the sidewalk of present most roads, the benefit that the cycleway position relationship is far different; In addition, the vehicle enter road side compound of turning right is also safer, before the right-hand rotation car passes the sidewalk, there is no blocking of greenbelt, and pedestrian's position is very clear, and people's line speed is slower, and the driver has enough time to determine whether give way; When the right-hand rotation car passes the sidewalk, when being about to enter cycleway, the speed of a motor vehicle is very low, and this moment vehicle heading with road direction near vertical, driver's visual line of sight is enough to cover the right side towards oneself sailing next bicycle, electric motor car etc., thereby determine whether give way, guaranteed can fierce collision not occur bicycle, the electric motor car because of sight line problem and fast running as traditional road.
As optimization, sidewalk, cycleway and underground interchange arrange sidewalk, cycleway sinking tunnel below the intersection region of the overground part of branch road.So design can supply the pedestrian, cyclists only; Pedestrian, bicycle are lowered to the sinking tunnel in advance in the crosspoint, by upper to ground behind the crosspoint, avoid like this its automobile with turnover left tunnel and right tunnel to bump, also improved the passage rate of automobile simultaneously, the driver needn't worry that pedestrian and bicycle are on the impact of own speed.
