Kind is implanted with green plants, and suspention cultivation box can be promoted to ecosphere by mechanical device and be planted or gathered in operation.To ensure to eat
Product safety, the product that ecological chain is designed as industrialized agriculture module does not enter human body food chain, and otherwise generates economic effect
Benefit, such as industrialized agriculture product can be flowers, can be biomass (being used for renewable energy), can be used as building materials raw material, Yi Jiyong
In papermaking etc..
4, rainwater-collecting and green plant trickle irrigation module: setting horizontal rain-harvesting trough in the bottom outside of arched retaining structure, and is lauched
Pipe connection, closes solar photoelectric glass when raining heavily, horizontal rain-harvesting trough collects the rainwater flowed down from outer surface, is transported to ground
In lower rainwater storage, and water pipe for drip irrigation is set, is watered with drip irrigation to green plant.In moderate rain and light rain, intelligent control system
System can keep solar power generation glass in open state, so that suspention cultivation box energy reservoir part rainwater；By adjusting intelligent control
The parameter of system processed can also make the closing in moderate rain and light rain of solar power generation glass.
5, vibration absorbing structure system: another innovative point of the invention is to use vibration absorbing structure, and main shock absorber elements are to adopt
With the suspention cultivation box of suspention, while the solar power generation glass of louvered can also play the role of absorbing.
Solar power generation glass as described above is the transparent power generating glass that intelligent control opened and closed and adjusted angle, is mounted on cylinder
On shape light steel skeleton grid.The solar power generation glass is controlled by intelligence control system.Intelligence control system can be according to external rings
Border variation determines folding and the opening angle of solar power generation glass.
6, noise control module: viaduct is urban transportation skeleton, and vehicle flowrate is big, is not allowed the noise effect of neighboring buildings
Ignore.Since the present invention is using closing building enclosure, advantage is created for noise control.The present invention is in concrete column side
Portion is additionally arranged sqouynd absorption lowering noise structure, the sqouynd absorption lowering noise structure can to plant green concrete (plantation shade plant) three-dimensional stack and
At being also possible to the sqound absorption construction of perforated metal panel liner sound-absorbing material, depending on concrete engineering.The function master of noise control
It to be realized by closed peripheral structure.Peripheral structure purifies cavity by closed internal layer thus and outer layer to be opened/closed purifies
Cavity composition, can play noise barrier action.The inner layer material and cladding material of interior gas purification chamber are using different-thickness
Clear sheet, to avoid coincidence effect.The sprayable fibrous material with photo-catalysis function of the cultivation box of the green plant of outer layer, to increase
Strong air cleaning and sound-absorbing and noise-decreasing effect (can be used as suspended absorber).
7, nightscape lighting: LED light is laid in the inside of building enclosure outermost layer glass, night lights can be city through glass
City increases beautiful landscape, while the night illumination as the auxiliary road in two sides.Upper and lower path is all provided with night artificial lighting system.
Above 7 subitems module is not well-separated, but plays the function of ecological viaduct as a whole.
Due to overpass at the both ends of its length and atmosphere be it is penetrating, in order to make automobile on overpass when driving
Tail gas does not diffuse into atmosphere as far as possible, is provided with transparent plugging structure at the both ends of overpass, and steep uphill into
Induction door is respectively set at mouthful and exit of down slope, and when overpass on automobile or lower overpass, induction door is raised above
It opens, when not having automobile, induction door is closed, and sufficiently vehicle exhaust can be avoided to be dispersed into atmosphere in this way.Transparent plugging structure
The watering tube of internal setting is connected to the water pipe for drip irrigation in outer gas purify cavity, unified to supply water, and transparent plugging structure also acts as
Increase the effect of illuminating area.The pollution imports and air filtration module being arranged on second transparent panel also function to circulation and purify
The effect of vehicle exhaust.
The invention proposes a kind of original novel overhead line structures, collect inner lane by closed building enclosure and produce
Raw tail gas is purified, and zero-emission or the negative emission of viaduct (single-layer or multi-layer) may be implemented.90% or more viaduct vault
Area installation transparent solar cell plate or solar power generation glass.The electric power of generation can be used for driving air-purifying module.
This was utilized to the first time of solar energy.
It is ecological oxygenation layer below building enclosure, vegetation converts solar energy into biomass energy, is the to solar energy
Secondary use.Solar photoelectric glass uses intelligent control, its opening angle is adjusted, and the ventilation and heat of viaduct are adjusted with benefit
Wet environment.Summer can play the role of sunshade, and winter can play insulation effect.(3) present invention is using adjustable building enclosure, in mist
Outermost solar photoelectric glass can be placed in off by haze Severe weather, only open row's solar energy of bottommost
Electric glass, or bottom is set into a row can open blinds, and place it in open state, by being driven by electricity for solar power generation, make
Air-purifying module keeps negative pressure, and from outside, sucking haze air is purified.Simultaneously by the collection of closed building enclosure
The tail gas that portion's passage layers generate is purified.(4) closed building enclosure and the air-purifying module of suspention can effectively shield and
Car noise is absorbed, prevents it from spreading out of viaduct.(5) present invention is especially using the peripheral structure of two sides suspention, and uses soft
Property bidirectional cable structure, suspention cultivation box on it, this absorbing combination can effectively absorb vehicle shape and sail to overpass knot
The vibrational energy that structure generates improves structure durability.It (6), can be extreme to avoid sleet heat etc. due to using enclosed construction
Weather is created comfortable to the adverse effect of driving environment, and by being adjustable the aerial temperature and humidity in passage layers using the sun
Driving environment.
Compared with existing overpass, main advantages of the present invention are the tail gas for utilizing closed system to collect motor vehicle emission, and
Purified treatment is carried out to tail gas with air-purifying module.Simultaneously compared with the semiclosed noise abatement wall of existing overpass, the present invention
The enclosed construction of proposition can thoroughly solve the noise problem of big flow traffic.The all standing photovoltaic power generation that the present invention is arranged is transparent
Building enclosure can make full use of the large area land resource of overpass to generate electricity, it is contemplated that the area of overpass covering is vast, and shows
There is photovoltaic power generation technology mature, this measure has significant energy economy & environment benefit, this is the light with the highway pavement that is laid in
The different another generation mode of volt power generation, power generation are not influenced by driving vehicle.
