Description

City overpass

Technical field:

The present invention is relevant with urban elevated road, especially with to intersect elevated road relevant.

Background technology:

Existing elevated road such as name are called " city overpass ", the patent No. is the technical scheme of ZL99114942.4, be based on late nineteen nineties China's motor vehicle and increase fast, urban traffic infrastructure but seriously lags behind, and caused urban traffic is serious to be stopped up and stops difficulty and the invention made.This invention " city overpass " has solved in the past, and urban elevated road is difficult to problem up and down, make it forming combination under the prerequisite of not destroying the various functions of original ground level road and between original ground level road, because of one deck road can stop, and solved the problem of parking difficulty simultaneously." city overpass " is though have about the inner solution of road self system vehicle and the two big advantages of parking, but cause the node of traffic jam, be the traffic diverging difficult problem at crossing, also not basic the solution is so it still belongs to the road system that connects pattern basically.Such as, no matter the magnitude of traffic flow in the intersection on the relative both direction in main highway section is big, still little, it is all equally lived together peacefully with the craspedodrome road, because the original function that this " city overpass " kept ground level road is constant, promptly the original traffic capacity of ground level road is constant, if but two such " city overpass " are crossing, when the magnitude of traffic flow of four direction was all quite big again, change had just taken place in situation.Because there is the through vehicles on the both direction when keeping straight on, need pass through communication channel 11, needs doubling just can finish craspedodrome for twice and pass through; Left-hand bend vehicle on the four direction also need be before or after by communication channel 11 once doubling travel.So when less important road section traffic volume flow is less, the degree that vehicle on the direction of main highway section is disturbed also can be not clearly, the timesharing if all relatively very big dereliction of four direction vehicle flowrate takes second place, obviously just can not satisfy the demand, travel and near communication channel 11, formation to be detained and to stop up because of continuous vehicle doubling, finally be affected completely.

The content of invention:

The purpose of this invention is to provide a kind of under all big situation of the vehicle flowrate of intersection four direction, all directions to pass through performance good, the city overpass that throughput is big.

The present invention is achieved in that

way street

9,10 courtyards that separate 20, the one-way street that is separated by courtyard 20 has communication channel 11, one-way street has the bottom road of connection and one deck road, the interlayer in one deck road and two layers of road leads the way 13, in the intersection along the courtyard 20 of the axis in the main highway section 22 that can lead directly to one deck road with main highway section 22, two layers of road are separated into the one-way street 9 that is separated from each other, 10, and the blocking-up less important highway section 23 that can not lead directly to one, the one-way street 9 in two layers of road, 10, the one-way street that is disconnected 9 in one deck road 3 in less important highway section, 10 access bridges 11 by leap courtyard 20 are connected, in the intersection, part one-way street 9 on two layers of road 4 in less important highway section, 10 link to each other and covered portion courtyard 20, the middle part, road that links to each other raises up and is connected to form across the two layers of road in main highway section 22 and the arch bridge 24 of the courtyard 20 on the axis thereof, the both sides flat is connected with two layers of road in main highway section 22, and its inboard has descending leading the way 13 to be connected with one deck road.

One-way street 9 on two layers of road 4 in less

important highway section

23,10 13 are connected with one deck road 3 by descending leading the way in the intersection, the communication channel 11 of crossing over courtyard 20 on 22 axis of main highway section is arranged on one deck road 3, have on main one deck road, highway section 3 along the up access bridge 13 of main highway section axis and connect two layers of road 4, main highway section, the one-way street 9 in two layers of road 4 in main highway section, 10 respectively have descending access bridge 21 to cross over the one-way street 10 in courtyard 20 and one deck road 3 on opposite on the axis of main highway section, 9 connect, and one deck road, less important highway section is along the one-way street 10 in the up 13 and two layers of road of leading the way of its axis, 9 connect.

Access bridge 21 is acute angle or right angle with main highway section 22 axis angles.

Two layers of road in main highway section 22 and up access bridge 13 extend and are connected to courtyard 20.

Late nineteen nineties, China's automobile annual production has only more than 100 ten thousand, and automobile annual production in 2005 has reached more than 560 ten thousand, the following several years also will increase this trend fast like not changing, concerning having felt the very severe big and medium-sized cities, various places of traffic environment pressure now, must not face " limitting little ", encourage the finiteness of automotive industrial policy and urban traffic resource, and country forbids city, the various places policy of " wide road, Grand Place " of building for the saving soil and constitutes all challenges all for the traffic environment in city for setting up saving property society.For this reason, the present invention is at the bilayer of existing " city overpass ", two-way separation intercommunication adds on the built-in basis of leading the way up and down, when mainly having solved two such city overpass and having intersected, all have under the traffic behavior of big flow again on all directions, how to make vehicle capable orderly, non-interfering problem by the crossing.The invention solves the crossing traffic flow when all directions are all big relatively, just must cause the phase mutual interference this to ordering weakness, will make this system of city overpass more become perfect, also have more science, practicality.

The specific embodiment:

The shunting through vehicles: (we are claiming main highway section 22 with the highway section of the relative both direction that the crossing through vehicles can directly be kept straight in the less important highway section 23 of " city overpass " intersection in the present invention, need claim less important highway section 23 by the highway section that communication channel 11 just can be finished the relative both direction of craspedodrome process when through vehicles is kept straight on) near the crossing suitable apart from the time, two one-way streets that are separated from each other 9 on two layers of road 4 of overpass, 10 is continuous to the inner space extension respectively, upwards strides across two one-way streets 9 on the main highway section then, 10 with less important highway section, opposite on two one-

way streets

9,10 link to each other.This in fact just forms 1 and connects two sections that less important highway section is separated by courtyard 20, crosses over the bridge crossing 24 in main highway section.So just solved the situation that original main highway section is divided into two less important highway section at the crossing, this has also just solved the mutual interference problem of straightgoing vehicle on all directions.

Shunting guiding left-hand bend vehicle: less important highway section is after shunting to through vehicles has been finished in the appropriate location, crossing, and the part road width of cloth of two one-

way streets

9,10 on the two floor road directly forms one downwards and leads the way and 13 arrive one deck roads 3.Two ends, less important like this highway section respectively two to lead the way 13, one be that less important highway section turns left to arrive the descending of one deck road 3 downwards by two layers of road 4 and lead the way 13; Article one, be directly to lead the way 13 by 3 arrival the up of two layers of road 4 of one deck road for meeting main highway section to turn left.

Left-hand bend vehicle operation order on less important highway section 23 and the main highway section 22 is respectively: one, turn left to main highway section 22 in less important highway section 23: after the through vehicles shunting is finished in less important highway section, the two floor road one-

way streets

9 or 10 the part road width of cloth directly sink to forming descending leading the way and 13 arrive one deck roads, a clinodiagonal communication channel 11 is built to one deck road 3 of main highway section another side in piggybacking one deck road 3, upwards building one by one deck road 3 in main highway section again leads the way 13 to two layers of road 4, main highway section up (this up leading the way can be to separating two one-way streets 9, extend 10 inner space, also can not extend and direct making progress), at this moment just to have finished of the left-hand rotation of less important highway section 23 to main highway section 22.Two, turn left to less important highway section in main highway section: the vehicle that turns left on the main highway section (has a plurality of positions selective in the appropriate location at crossing, turn left again after equally also can selecting to extend internally or do not extend direct left-hand rotation, here Fig. 2-4 table three kind of form) respectively build one deck roads 3 that a downward access bridge 21 directly connects the opposite roads by two one-

way streets

9,10 in two layers of road, main highway section, one deck road 3 that relends less important highway section is upwards built one and is arrived the up of two layers of road 4, less important highway section and lead the way 13.Finished main highway section so again to travelling of turning left in less important road.
