Abstract

The invention relates to a low-stand bikeway system based on a side road. The bikeway system comprises low-stand occupation road modules, a bike parking platform, an under-bridge motor park, a C-shaped bridge bypassing structure, inlet and outlet fences for limiting width and side channels for entering or leaving the bridge, wherein each low-stand occupation road module is composed of a door-shaped supporting frame, a frame panel, a frame cross beam, a frame supporting column, a cross beam and a supporting column connection plate. According to the invention, a pedestrian overpass is used to erect a bike channel with the same height so as to span a highway, a C-shaped bridge bypassing manner is used to bypass the pedestrian overpass, the lower side of the supporting frame is transparent, and a common temporary motor park can be built on one side of the bikeway; the bikeway is thoroughly separated from a motor vehicle lane, and an over-bridge bike parking platform adopts a lightweight steel structure or concrete support structure, thus the construction cost is greatly lowered; and in order to guarantee the safety of bike riders, increase the riding speed and providing technical guarantee for advocating environmentally-friendly traveling, a special bike leasing service system can be built by virtue of the low-stand bikeway system provided by the invention.

Description

Low frame bikeway system based on bypass

Technical field

The present invention relates to a kind of low frame bikeway system, belong to the graded crossing of road, the mutual connection technique field of overpass based on bypass.

Background technology

Current most of energy sources is a fossil fuel: coal, oil and natural gas, and with present operating speed, known residue colliery mineral reserve will run out after about 200 years, and oil and natural gas will use totally in less than 100 years.Fossil fuel can cause a large amount of environment pollutions in use, comprising the greenhouse gases that cause global warming.The permanent resident population of Beijing had reached 1,755 ten thousand people in 2009, had a net increase of 51.5 ten thousand on motor vehicle the whole year.By the end of the year 2010, nearly 5,000,000 of Beijing's motor vehicle, wherein the private car accounts for 80%; And private car's working strength is too high; Go 1.5 ten thousand kilometers every year, surpass the twice in Tokyo, Beijing traffic goes from bad to worse; Daily blocking up reaches 5 hours, and the annual loss that causes because of traffic jam is equivalent to 3.6% of the GDP of Beijing total amount; At present, though share of public transportation is carried to 38.9%, track traffic can't bear the heavy load.And the ratio of using cycling trip by 1986 62.7% drop to 2009 18.1%, also descending so far.

In recent years, popular along with the great development of China's automobile industry and car, the condition of cycling and environment are worse and worse.Along with the quickening of urban construction, motorway is repaiied wideer and wideer, but the nonmotorized vehicle lane more and more narrow; Even much all occupied, like the interim car park of half conduct of bypass, and second half is used for the turnover of car; If catch up with traffic congestion, automobile all occupies all roads, and bicycle can only bore in the automobile seam; Make that riding of bicycle is abnormally dangerous, even cause many traffic accidents.Simultaneously, the place of depositing bicycle is also fewer and feweri, and the quick growth of automobile makes the living space of bicycle receive serious extruding.

China is a bicycle big country, and the fifties in last century, the bicycle flow that springs up in the city was once likened to " Great Wall of moving " by the foreigner to the eighties; Even if bicycle still is the trip instrument that the common people be unable to do without now.For example, Beijing Municipal Government announces " building humane traffic, scientific and technological traffic, green traffic action plan (2009-2015) ", and the overall trip general layout of Beijing's traffic in 2015 will become; Public transport accounts for 45%; The car trip accounts for 22%, and taxi accounts for 8%, and bicycle will reach 23%.In order to alleviate the urban traffic congestion and to improve urban environment, Beijing will progressively build " slow-moving traffic system "; For this reason, public security and traffic control department are are studying and defining the administrative provisions that help bicycle traffic, simultaneously, revise and abrogate the administrative provisions that are unfavorable for bicycle traffic, include bicycle in whole city traffic programme.

Summary of the invention

For thoroughly changing the environment of metropolis cycling; Increase the utilization rate of road; The present invention provides a kind of low frame bikeway system based on bypass, bike lane is thoroughly separated with the motor vehicle track, to ensure cycling safety; Improve riding speed, for the environmental protection trip provides technical guarantee.

Technical scheme of the present invention is following:

A kind of low frame bikeway system based on bypass is characterized in that: this occupation road system comprises a plurality of bikeway modules, side bridge passage and cross street bicycle passage up and down; Each bikeway module contains a type support frame, bridge deck and load guardrail; Described door type support frame highly is the limit for height through the defined vehicle on the isolation strip at bypass two ends, the below is penetrating fully; This type support frame is made up of pillar, framework panel and cruciform bracing; Said bridge deck are fixedly connected with the framework panel of door type support frame, form bypass bicycle passage, are provided with at least one bicycle parking platform in bicycle passage one side, and this bicycle parking platform is arranged on adjacent two door type support frames; The bridge passage is located at the opposite side of bicycle passage about the described side; Described street bicycle passage excessively and overpass have equal height, are made up of bridge deck and load guardrail, support through the supporting bracket that is connected in overpass, are connected with bypass bicycle passage.The load guardrail adopts frame construction, and the center is higher, and both sides are lower.

Low frame bikeway system based on bypass also comprises the C type around bridge construction, and this C type adopts a plurality of occupation road modules to make up with forniciform mode around bridge construction, forms the low frame bikeway that side is walked around the street overline bridge.

Side up and down bridge passage upper end is provided with the discrepancy fence that electric vehicle that restriction exceeds width gets into, and the side platform is set behind the fence of coming in and going out supplies bicycle to circle round to get into the bicycle passage.

The present invention has following characteristics and high-lighting effect: 1. bike lane is thoroughly separated with the motor vehicle track, formed the occupation road of bicycle, for ensureing cycling safety, raising riding speed, promotion environmental protection trip technical guarantee is provided; 2. set up low frame bikeway system with the modular mode of occupation road, on the isolation strip at road bypass two ends, do not take special region based on bypass; Effectively utilized existing space; 3. through C type bridge passage about bridge mode, the passage that relies on overpass and side, make up the passage of the low frame bikeway of turnover, 4. adopt lightweight steel construction or concrete support structure and modular mode; Can reduce construction cost significantly; 5. construct car park under bicycle parking platform, the bridge, embody multi-functional, multipurpose better, 6. based on this system; Can set up and be used for the special leasing system of bicycle; The section that in the urban district, blocks up, the junction of subway station are provided with the passage and the Cycle Hire point of bridge up and down, make cycling trip easy more, with the operation that standardizes.
