Abstract

A divergence type divided expressway comprises an inlet and an outlet for buses to enter and exit expressway, as well as an inlet and an outlet for trucks to enter and exit expressway. Bus driveways and truck driveways are arranged in sequence from the central separating belt of the expressway to outside, and are separated by isolation belts; and connection openings communicating the bus driveways and truck driveways are arranged at intervals. The utility model can improve safety factor in the driving of expressway and traffic passing capability of expressway, ensure vehicles can enter and exit expressway conveniently and safely, improve the durability life of the expressway and prolong maintenance cycle, and reduce the operating cost of the expressway.

Description

Separated type highway with lanes

Technical field

The utility model relates to a kind of speedway, the speedway that especially unidirectional Four-Lane Road and Four-Lane Road are above.

Background technology

At present, the speedway of China is that visitor, lorry mix unidirectional two tracks of row or the structural form in three tracks substantially, and wherein a track is a fast, and all the other are runway.Should travel at outermost track (right lane) though limit lorry, in the vehicle ' process, the phenomenon ubiquity of any road occupying of lorry.Along with socioeconomic continuous development, highway visitor, shipping throughput rate can continue to increase; Visitor, lorry mix the further aggravation of phenomenon of row on the speedway, and this will bring very big hidden danger to the operation of speedway.At first, the speed limit difference that visitor, these two types of vehicles of goods move on speedway, the two mixes row, and traffic safety hidden danger is very big; The second and since lorry particularly heavy goods vehicle travel not according to fixed course, reduced the application life of road surface integral body, increased maintenance cost; Simultaneously, the phenomenon of losing the junk product from lorry is unrare, and the vehicle of running at high speed is caused very big harm; The 3rd, because accounting for fast, the part lorry travels, at night, its running light produces strong dazzle to the vehicle that travels in opposite directions, badly influences the traffic safety of vehicle in opposite directions; The 4th, at present the load of China's part six-lane speedway has surpassed in the six-lane speedway 24 hours of national regulation the highest vehicle flowrate standard by 50,000, along with expanding economy, the increase that personnel, goods and materials flow, the six-lane speedway can not adapt to the transport power requirement of national communication trunk line, and the speedway on eight tracks and eight tracks reach will be built in a large number; The 5th, from the operating condition of the existing two-way eight track speedways of China, at the slip-road place, the number of track-lines that will pass through during owing to vehicle turnover speedway and road increases, vehicle retardance herein, traffic accident showed increased.

The utility model content

Mix problems such as the existing traffic safety hidden danger of row and speedway maintenance cost height, load are big in order to overcome present speedway visitor, lorry, the utility model provides a kind of novel high speed highway; This speedway not only can guarantee the traffic safety of vehicle on expressway, and can carry out the road structure design respectively according to the size of road surface load, can reach economy, the reasonability of speedway structure, can guarantee the durable years on road surface again, reduce the road maintenance cost; Simultaneously, can simplify the structure of the entry and exit of speedway, reduce construction costs.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of separated type highway with lanes, comprise import, the outlet of import, outlet and the lorry turnover speedway of passenger vehicle turnover speedway, the median strip of this speedway outwards sets gradually passenger vehicle runway and lorry runway, described passenger vehicle runway and described lorry runway are separated by the isolation strip, and every a segment distance connected entrance that described passenger vehicle runway and described lorry runway are connected are set.

Described passenger vehicle runway and lorry runway are provided with hardened verge, marginal strip or earth shoulder.

Described passenger vehicle runway and described lorry runway all are at least unidirectional two tracks.

Described lorry runway left side is provided with lorry fast and curb respectively, and described passenger vehicle runway left side is provided with passenger vehicle fast and curb respectively.

The import of passenger vehicle turnover speedway, outlet are provided with ring road with lorry runway grade separation downwards at its hardened verge place, and the directly outside usual friendship of import, outlet of lorry turnover speedway is provided with ring road; Import, the outlet of passenger vehicle and lorry turnover speedway are pooled to a place and lead to charge station or service center.

Between described ring road the isolation strip is set.

The beneficial effects of the utility model are, can improve the safety factor of turnpike driving, improve the bus capacity of speedway, guarantee that vehicle can pass in and out speedway convenient, safely, improve the durable years of speedway and prolong maintenance cycle, reduce the operation cost of speedway.

The specific embodiment

Fig. 1 is the plan view from above at place, speedway entry and exit.In Fig. 2, outside from the central partition 8 of road central authorities, be followed successively by marginal strip 6, passenger vehicle fast 1, passenger vehicle runway 2, hardened verge 5, marginal strip 6, isolation strip 9, marginal strip 6, lorry fast 3, lorry runway 4, hardened verge 5, earth shoulder 7; Isolate passenger vehicle track and lorry track with isolation strip 9, every about 3km, the isolation strip is disconnected, passenger vehicle track and lorry track are communicated with; The hardened verge 5 in passenger vehicle track road surface near charge station or service center the time is widened and is looked for domatic to become Entrance ramp 11 and the exit ramp 13 of passenger vehicle track into and out of speedway downwards, simultaneously, the slope is all upwards looked in corresponding lorry track herein, satisfies the requirement of relevant design standard into and out of the headway size in the passenger vehicle track of speedway with assurance; The directly outside usual friendship in lorry track is provided with the Entrance ramp 12 and the exit ramp 14 of lorry track turnover speedway.The visitor of turnover speedway, the ring road of lorry are all by relevant technical specification design.

In Fig. 3, passenger vehicle inlet 11, lorry inlet 12, passenger vehicle outlet 13, lorry outlet 14 are pooled to a place and lead to charge station or service center.It constitutes presses the ring road design; R2 is the turning radius of long-traveller car; Into and out of between the ring road of speedway, establish the isolation strip.

In Fig. 4,11,13 are respectively the import and export ring road of passenger vehicle turnover speedway; 15 accessory channels for freeway management personnel and vehicle make things convenient for the charge station of speedway both sides or the contact of service center, also can be used as Emergency Vehicle Lane and use, and separate with movable isolation pile at ordinary times.Except that this passage, the linking-up road of bidding standard in addition also.

In Fig. 5-6, passenger vehicle passes through in bottom, lorry track into and out of the ring road of speedway, and its headway must satisfy the requirement of correlation technique standard; This headway meets the demands by the rise in lorry track.Lorry carriageway surfacing load calculates by heavy goods vehicles, equal big than passenger vehicle track of the one-tenth-value thickness 1/10 of deck and surface layer in its structure level.

The all technical datas of this speedway all should satisfy the requirement of correlation technique standard.
