Subway is that certain scale is arrived in urban development, for meet in city, the demand of long distance passenger traffic, alleviates bus transport pressure and the railway transportation trade opened.Most subway can be built in tunnel below urban road, but such tunnel is often comparatively dark, for the city having flourishing lithic drainage, easily destroys the water channel of deep under ground.Not only cost is higher to deep-cut subway in addition, and high ferro builds cost quite, and during building tunnel, have the risk of surface collapse, can cause serious consequence.Addressing in crowded urban district, build subway station and be also not easy, sometimes also will do a large amount of relocating work, extra increasing builds difficulty.
Current highway tunnel mainly contains mountain tunnel, Chuan Jiang tunnel, seabed tunnel etc., and object is for passing through natural objects, connect two side areas, facilitate two ends vehicle, personnel's dealing pass through.Nowadays tunneling technology is mainly limited to traditional shield technique, its shortcoming and subway tunnel similar, seldom have as port Zhuhai and Macao bridge use immersed tube tunnel technology.Tunneling object also seldom has alleviates traffic above-ground pressure as tunnel, Bund in Shanghai, protection civic landscape.
Summary of the invention
The technical problem to be solved in the present invention is the above-mentioned defect how overcoming prior art, provides a kind of three-dimensional transportation system for urban main road.
For solving the problems of the technologies described above, this three-dimensional transportation system for urban main road, comprises arterial highway and the branch road crossing with arterial highway, and arterial highway comprises viaduct and is positioned at the ground floor below viaduct, and ground floor has subway tunnel; Viaduct is provided with the column supporting viaduct, three arranged side by side of column is one group, the soffit all having with tunnel soffit and tunnel upper surface that middle center stand column gos deep into subway tunnel is connected, the column on both sides and the sidewall of subway tunnel are connected as a single entity, till all columns are all deep into tunnel soffit.
Design like this, column both supported viaduct, supported ground floor again, and all wt reaches subway tunnel soffit, then reached below soil layer.Compared with original high racks road, column pile foundation can not be too dark, is not easy the water channel destroying deep under ground, is applicable to the city of lithic drainage prosperity; And subway tunnel soffit is large to the contact area of below soil layer, decreases geostatic pressure, effectively alleviates foundation settlement.
As optimization, the subway tunnel left and right sides is provided with left tunnel and right tunnel, and three is box culvert tunnel.Design like this, pass through next, that go both direction vehicle respectively for left tunnel and right tunnel, can play the effect alleviating traffic above-ground pressure, the more important thing is the utilization rate substantially increasing original path space.
As optimization, at large-scale crossing, by underground interchange, left tunnel is connected with 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 upper strata, and underground interchange is come in and gone out ring road and leg parallel, left tunnel and right tunnel is entered obliquely from branch road ground, current in dual-way vehicle.Design like this, if vehicle is wanted to turn right and arrived right branch in left tunnel and right tunnel, turn 90 degrees on the nearest ring road right side, arrival left branch of turning left if want, only need moving ahead turn-takes 270 degree by next ring road arrives right branch ground, then keeps straight on and arrive left branch by crossing; If a road vehicles thinks that right-hand rotation enters tunnel, arterial highway, turn 90 degrees on the nearest ring road right side, if think, left-hand rotation enters tunnel, arterial highway, only need move ahead by crossing, turn-take 270 degree at next ring road, effectively alleviates traffic above-ground pressure.
As optimization, at the large-scale crossing that building is intensive, into ring road, arterial highway to be connected with right tunnel with left tunnel with turning left by arranging the ring road that turns left out on arterial highway; With ring road of turning right out, branch road to be connected with right tunnel with left tunnel into ring road by arranging to turn right on branch road; Turn left ring road out from right left tunnel skew back upwards straight-through arterial highway ground floor, turn right ring road out from right tunnel right hand steering branch road underground, then ground floor is led to obliquely, these two ring roads are the ring roads tunnel, be symmetrical in branch road and also have two ring roads entering tunnel, also there are four such discrepancy ring roads in left tunnel, 8 discrepancy ring roads altogether near each crossing.Design like this, if vehicle is wanted to turn right and arrived right branch in right tunnel, select ring road of turning right out recently directly to arrive right branch ground, turn left to arrive left branch if want, select ring road arrival ground, trunk road of turning left out recently, proceed to junction ahead and turn left again and can arrive left branch; If road vehicles thinks that right-hand rotation enters tunnel, arterial highway, selecting to turn right recently directly enters tunnel into ring road, if think, left-hand rotation enters tunnel, arterial highway, only need turn left arrive arterial highway at junction ahead, proceed to into ring road mouth down to tunnel.
As optimization, be provided with the collecting and distributing space of pedestrian, two layers, underground below box culvert tunnel, the collecting and distributing space of pedestrian, two layers, this underground is rectangular, and central area is subway safety check, charge, Transfer Hall, and branch road crossing place is provided with access, two layers of pedestrian collecting and distributing space, underground; Two layers, the underground collecting and distributing space peripheral of pedestrian is provided with peripheral collecting and distributing passage, can certain area be hewed out outside peripheral collecting and distributing passage, news-stand, Mini Supermarkets, public lavatory, all-purpose card recharge point, municipal project payment point, train ticket Self-service Tickets etc. handy service for the people facility and project are set.Design like this, compared with crossing tunnel, street with conventional pedestrian, this collecting and distributing space function is more, more convenience-for-people, and has repaiied in the lump when constructing road, without the need to additionally planning, addressing, builds.
