Description
Technical field:
The utility model belongs to the traffic engineering field of having stable political situation, city, particularly relates to a kind of underground trolley bus tunnel that combines with surface road.
Background technology:
Trackless trolley car directly utilizes electric power as power, does not have explosive motor, not discharging waste gas, noise is little, pollute little, since being born, because of its plurality of advantages obtains using comparatively widely in various countries' urban ground traffic, occupied critical role, but also had the following disadvantages:
1, because trackless trolley car is connected power supply by the fixing rod pantagraph current collector of overhead type contact system and vehicle (be commonly called as plait, also claim current colector, be made up of with trolley head trolley pole).
1) fixedly overhead type contact system must be set, as web, it is bigger that difficulty is set, and landscape effect is not good, and maintenance is also bigger.
2) necessary fixed vehicle running route and track, the alerting ability of circulation line adjustment and combination is relatively poor.
2, because trackless trolley car and other vehicles mix row, and the trackless trolley car speed of a motor vehicle is lower, can not adapt to the requirement of modern city ground communications, also aggravated blocking up of urban ground traffic simultaneously.
3, because traffic lights are controlled, vehicle pass-through speed more can't be mentioned in the same breath with track traffic.
Because above-mentioned deficiency, along with the maximization in city, the increase of road number of track-lines, the raising that goes out line speed, the application of trackless trolley car more and more is restricted in the urban ground traffic in recent years, and the diesel oil motorcoach is propagated its belief on a large scale on the contrary, obtained fast development, when bringing quick, motor-driven, flexible advantage, its strong noise, maximum discharge, high pollution have also brought comparatively serious waste gas, noise emission to the city, become a big problem in puzzlement city, various countries, simultaneously also expend a large amount of oil resources, aggravated the anxiety of oil supply.
The utility model content:
Problem at the background technology existence, the utility model people proposes, if utilize the underground space of surface road, be arranged to the underground passage way that combines with surface road, designated lane as trackless trolley car, then fixedly the setting of overhead type contact system and with the contacting of trackless trolley car rod pantagraph current collector, problems such as track will be out of question, passage rate can improve greatly, add the non-exhaust emission that trackless trolley car itself is had, low noise, oligosaprobic advantage, then trackless trolley car still has very strong survivability, still can in the city traffic system, play a significant role, can also vacate the ground communications space, alleviate the ground communications pressure that the vehicle sharp increase based on dolly brings.
In addition, compare, have following characteristics with track traffic:
1, passage rate and carrying capacity: effect with public transportation lane, the trackless trolley car passage rate is a little less than even not being lower than track traffic, single track carrying capacity is lower slightly, can adopt the super wide vehicle or the double-decker that are similar to the airport ferry bus, improve bicycle carrying capacity, major urban arterial highway can be provided with two and come two to go to four tracks, whole carrying capacity higher (be equivalent to track traffic about 50%).
2, passage building cost and construction period: underground passage way can adopt foundation ditch open cut method, pit top-down, foundation ditch cap excavation method or put sloping cut and cover tunneling, and cost is low, and speed is fast, and risk is little.And shield method or subsurface excavation method are generally adopted in the underground rail traffic, and speed is slow, and the cost height has a big risk.
3, vehicle manufacturing cost and cycle: the vehicle cost is well below rail traffic vehicles, and domestic trackless trolley car vehicle manufacturing technology is very ripe, and the manufacturing cycle is short, can meet the demands fast.
4, operating cost: the passage maintenance is little during the operation, expense is low, and the trackless trolley car Operating Expenses is also lower.
5, the property extended: along with widening of surface road, underground trolley bus tunnel also can correspondingly be widened, and increases the track.The underground rail traffic then is difficult to widen.
6, the utilization of the underground space: the trackless trolley car turn radius is little, hill climbing ability is big, its passage can utilize the underground space setting of surface road fully, the general underground space that does not need to pass through other surrounding buildings because of the turn radius problem, and passage and station setting depth as shallow, take underground space depth as shallow, personnel are comparatively convenient up and down.And underground rail traffic turn radius is big, often need to pass through the underground space of other surrounding buildings during turning, and because tunnel structure needs, climbing needs, the tunnel and the station setting degree of depth are dark because of the turn radius problem, it is big to take the underground space degree of depth, and personnel are also not too convenient up and down.
7, resultant effect: can make full use of the underground space, can be in conjunction with transforming surface road, the performance of surface road and durability can reach the level of elevated line.
