Description
Technical field:
The invention belongs to the traffic engineering field of having stable political situation, city, particularly relate to a kind of underground utilities and trolleybus integrated channel that combines with ground level road that adopt.
Background technology:
Trolleybus 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 trolleybus is connected power supply by the fixing rod pantagraph current collector of overhead type contact net and vehicle (be commonly called as plait, also claim current-collector, be made up of with trolley head trolley pole).
1) fixedly overhead type contact net must be set, as cobweb, it is bigger that difficulty is set, and landscape effect is not good, and maintenance is also bigger.
2) necessary fixed vehicle travel route and track, the flexibility of working line adjustment and combination is relatively poor.
2, because trolleybus and other vehicles mix row, and the trolleybus speed of a motor vehicle is lower, can not adapt to modern city traffic above-ground requirement, 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 trolleybus more and more is restricted in the urban ground traffic in recent years, and the diesel oil motor bus 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 pollution to the city, become a big problem in puzzlement city, various countries, simultaneously also expend a large amount of petroleum resources, aggravated the anxiety of oil supply.
In addition, urban pipelines such as electric power, communication, feedwater, draining, coal gas, natural gas mainly adopt direct-buried mode at road, greening scope difference direct-burried at present, pipeline is buried underground and overhauled certainly will need be to urban road " belly breaking ", add that pipeline buries asynchronous with the repair time underground, urban road " belly breaking " rises one after another, and urban traffic is caused have a strong impact on.
Summary of the invention:
Problem at the background technology existence, the inventor proposes, if utilize the underground space of ground level road, be arranged to the underground comprehensive tunnel that combines with ground level road, designated lane as trolleybus, then fixedly the setting of overhead type contact net and with the contacting of trolleybus rod pantagraph current collector, problems such as track will be out of question, passage rate can improve greatly, add the non-exhaust emission that trolleybus itself is had, low noise, oligosaprobic advantage, then trolleybus still has very strong vitality, still can in the urban traffic system, play a significant role, can also vacate the traffic above-ground space, alleviate the traffic above-ground pressure that the vehicle sharp increase based on dolly brings.
In addition, compare, have following characteristics with track traffic:
1, passage rate and handling capacity: effect with public transportation lane, the trolleybus passage rate is a little less than even not being lower than track traffic, single track handling 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 handling capacity higher (be equivalent to track traffic about 50%).
2, passage building cost and construction period: underground comprehensive tunnel can adopt foundation ditch cut and cover 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 hidden construction process 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 trolleybus vehicle manufacturing technology is very ripe, and the manufacturing cycle is short, can meet the demands fast.
4, operation costs: the passage maintenance is little during the operation, expense is low, and the trolleybus cost of business operation is also lower.
5, the property extended: along with widening of ground level road, underground comprehensive tunnel also can correspondingly be widened, and the track increases.The underground rail traffic then is difficult to widen.
6, the utilization of the underground space: the trolleybus turning radius is little, climbing capacity is big, its passage can utilize the underground space setting of ground level road fully, the general underground space that does not need to pass through other surrounding buildings because of the turning 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 turning 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 turning 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 ground level road and urban pipe network system, the performance of ground level road and durability can reach the level of elevated road.
In sum, technical problem to be solved by this invention provides underground utilities and the trolleybus integrated channel that combines with ground level road, solves the problem of burying underground of application problem and the city non-dangerous pipeline of trolleybus in the modern city traffic.
