Underground fast traffic net structure
" underground fast traffic net structure " belongs to building engineering field.As everyone knows, city congested in traffic and blocking is one of municipal government major issue of being eager to solve, and the serious obstruction of city vehicle has caused for national economic development and development and seriously influences.A country will develop, and at first is the development of communications and transportation, and from the development of all developed countries of the world, wherein one of most important sign is the modernization of communications and transportation.
Country will develop, and the city is crucial, the development in city, and key must solve as early as possible, the communications and transportation problem that the decision urban economy is built the development speed key.There are many economic experts and relevant authority to propose the scheme and the imagination of much dealing with problems, for example, at the urban construction underground railway, as metropolis of other developed countries or the like.Solve the traffic problems in city, should analyze according to the concrete condition in city, therefrom find the key point of problem, and according to actual conditions, make the planning of feasible scheme and embodiment, the anxious key to be solved of Urban Transportation is: the quantity of motor vehicle is very big, and it is annual all in swift and violent growth, existing traffic is serious again is not enough to use, cause very serious traffic jam, and the thing followed is that traffic accident continuously takes place, and therefore, solving that vehicle carries fast is the key that transport solution blocks.And the key that provides vehicle to carry fast is that enough highway transportation lines should be arranged.On the existing highway transportation line in city, transform, the land used of newly-increased highway perhaps be provided by a large amount of removals, this be very difficulty and expend huge engineering, thereby also be impracticable scheme.Propose thus to underground development, set up underground passage, just become Urban Transportation, promoted unique scheme that economic construction develops, how to realize and get through the underground transportation in city? we think at the urban construction underground railway, do not solve the serious root problem that blocks of vehicle transport in city.The actual mode of occupation of underground railway from many developed countries city, basically all be the transportation problem that solves the city stream of people, underground railway also of no use solves the transportation deficiency of vehicle on the ground, the actual conditions in city are the serious obstructions that solves vehicle on the ground, rather than the stream of people's conveying, therefore, the construction experiences of simply applying mechanically external underground railway is the actual conditions that can't solve the city.To fundamentally solve the urban traffic blocking problem, and build feasible scheme of City Underground Transportation problem, promptly below the highway of incity, city, build single file or many rows' driving rapid transit net.And the access of setting up the underground traffic net at the place, many traffic main arteries in city, the underground traffic net can be arranged in the busy section of town in city, and directly be switched to the suburb in city, like this with so that tale quale traffic above-ground when blocking, needs just can roll the city away from about two hours, and on underground traffic net supply line, at most only just can roll the city away from half an hour, so not only solved the serious problem of blocking of ground transport, but also improved transport energy greatly, build the creation advantage that priority should be given to the development of transport for developing the economy, to the management method of underground traffic, its rights and interests also are very big.
Build city underground fast traffic net scheme, mainly propose at the city actual conditions.Promptly at urban construction underground fast traffic net, it is the scheme that can't solve the car blockage problem on the urban ground for many years for solving, the planning of this technical scheme and engineering design, and construction all can be finished under the situation that does not influence traffic above-ground basically fully, in work progress, be not afraid of the influence (the main employing prevented rainwater and the phreatic measure of row) in rainy season, pollution to ground is little, again because with being linked to be integral body greatly, many mechanical calculation problems all are easy to solve particularly seismic design of structures requirement in its structure design.The selection of structural meterials and use.Technical requirements in construction, and the pollution of the expansion that causes of ground construction, to the direct influence that the ground highway uses, all accordingly got rid of influence of construction or the like rainy season.Thereby construction investment also can be than the small investment of overhead stereo highway on the ground, again because knotting of underground pleased fast network of communication lines mainly is the design scheme of travelling that solves automobile, thereby more much smaller than underground railway.Construction can divide multistage to carry out simultaneously.The selection of constructional materials is again a reinforced concrete structure, in conjunction with new " antiseismic and shock-absorbing installation for building " and " shock absorbing arrangement for buildings ", the use of two patent of invention technology.From the project of vital and lasting importance that the opposing earthquake disaster is destroyed, we believe that the traffic jam in city and other social concerns that cause thus can solve substantially for many years.
" underground fast traffic net structure " shown in Figure of description, underground fast traffic net structure, its structure can be a garden shape, the shape of a hoof or polygon such as Fig. 1; Underground fast traffic net structure arranged outside " antiseismic and shock-absorbing installation for building " and " shock absorbing arrangement for buildings " are as Fig. 2; Extract duct in the underground fast traffic net structure such as Fig. 3; Segmentation setting in the underground traffic net, car inspection and repair station and traffic safety inspection post.
The explanation of underground fast traffic net schematic design, China in recent years, many big or middle cities all are subjected to the vibration effect of earthquake, transition along with earth geology, its earthquake effect will progressively increase, so this patent invention engineer prompting: every underground construction project of vital and lasting importance " antidetonation shock attenuation " design, otherwise consequence is serious, has endless trouble.
