Where is the development space of Hefei town future?
"Subterranean Hefei " be well worth doing
As the development of modernization of Hefei city town, the already severe refashion such as safety of waste of pollution of insecurity of downtown land natural resources, environment, traffic jam, the sources of energy, take precautions against natural calamities made an appointment with a city develop continuously. In light of the road transportation that cares from the citizen only, its are integrated speed has put delay, car has an area to drop quickly with restricting the speed of 20 ％ of 15 ～ every year to urban viatic. If Hefei city still will go to enlarge urban area onefoldly henceforth, embezzlement is many farmland, the development road of type of booth flat bread, will solve urban communication problem hard already, cause bigger traffic jam possibly again. So, where is the development space of Hefei town future? Li Yixiang of senior engineer of class of office of Anhui land natural resources, professor thinks, the answer is underground.
The century of subterranean space
Li Yixiang says, the development of modern city is sure is stereo combination, on its demand land, subterranean synchronism is developed. 19 centuries are the century of the bridge, 20 centuries are high-level architectural century, 21 centuries are the century that development uses subterranean space.
Why to say so? Its reason: It is to only development uses subterranean space ability to alleviate the outstanding contradiction of urban development space and problem. The city relies on to circumjacent area to develop, can get the limitation of land natural resources. The city develops to headroom, establish a high level, long wear road and crossroads high, can accentuate again construction density of the city, well-advised choice is develop to underground; 2 it is development it is OK to use urban underground space resource conservation, create new development industry, wait like network of transportation of drive a vehicle of business street of bazaar of the subway, underground, underground, underground; 3 it is to develop subterranean space to be helpful for raising urban air defence to prepare for war ability, take precautions against natural calamities reduces calamity capacity. 4 it is development underground space but managing and many land natural resources, also be helpful for environmental protection, made sure the ground has more greenbelt, subterranean space can divide administrative levels to develop, it is OK that below specific conditional go to the fields dimensional development is used the development utilization rate on prep above ground. 5 it is subterranean space development uses as more original than having its as photograph of the space on the ground part, the space on the ground of excel of a lot of respect such as sex of subterranean space constant temperature, constant wet sex, adiabatic sex, shading sex, air-tightness, spatial, security.
Experience of provincial development success
Our country is used in the development of subterranean space on gained remarkable success, accumulated many experience. Beijing was built with the plan and construction many subway route and many underground are versed in Cheng, among them the area mixes ZhongGuanCun on the west development of space of underground of Beijing century city uses extraordinary success, zhongGuanCun on the west on area ground, underground is developed integratedly, use urban underground space combinative city communication, jockey underground synthesization of systematization, municipal cop, use subterranean space to undertake be handlinged integratedly.
Shanghai geology environment is not favorable the development of subterranean space, silty, stream arenaceous distributing extensively, but Shanghai exploration uses aegis compose channel technology, technology carrying a canal on the head, large technology of heavy canal channel, finished a batch to have representative subterranean space project, like line of mainstay of subway of central the city zone, road (or the person goes) traffic channel, sink type underground square, plan to was controlled 2010, the subway that Shanghai will build 312 kilometers is basic network [link widoczny dla zalogowanych], tubal network is joint synthesis of channel, underground, jump over project of the space below river channel and other places.
Hefei city regards the Anhui province as provincial capital, developing big city, the development of its underground space and its position do not suit. The funk hole that digs except 669 time and share are single beyond parking lot of high-level architectural underground, do not have the development of the system that has subterranean space to use almost, also did not have the special program of subterranean space. As the development of Hefei modernization city, urgent need undertakes the program of subterranean space and construction, the respect waits in link of technology, development, provincial more mature experience can be drawn lessons from for me.
Make subterranean Hefei
Develop subterranean space [link widoczny dla zalogowanych], this is to involve the major issue that to prospective Hefei modernization metropolitan construction strategy plans, the sense is great and far-reaching. Li Yixiang thinks to should have done the work of this a few respects against a rainy day currently.
One, the resource consciousness that establishs subterranean airspace, integrated development watchs the city with stereo establish, strengthen the management of subterranean space. Be in early U.N. was subterranean space important rich certainly 1981. Space of Hefei city underground is resourceful, the advantage is clear, on one hand geological ambient conditions is favorable, except south silty layer mixes along the line of river of the name of a river in Anhui Province and partial region growth outside shedding arenaceous layer [link widoczny dla zalogowanych], major area is agglutinant earth of the 4th department, the 3rd department and gules sandstone [link widoczny dla zalogowanych], the development of facilitating underground space; On the other hand space of Hefei city underground was not developed basically, building of layer of high level, freeboard is not much [link widoczny dla zalogowanych], subterranean space develops latent capacity big, difficulty is little. Proposal Hefei municipal government inspects subterranean space come at the resource such as subterranean mineral resources, groundwater, land together look upon, establish stereo the idea that turns urban natural resources, the category that regards resource of a whole as to bring into land natural resources to manage Hefei city ground, headroom and underground.
2, the investigation that has urban underground space. Begin urban geology to work, fill make Hefei city three-dimensional geology write a picture, the space that investigates project of Hefei city of all kinds underground to include of all kinds underground to manage a network distributings.
3, development of space of underground of city of work out Hefei uses overall planning and integrated control sex to plan in detail. Once subterranean project builds hind, the difficulty that be transformed to its and rebuilds is quite great, cheng of unlike ground go to work can rebuild with was being torn open, subterranean project must combine overall planning of project geology condition and city to relapse argumentation, scientific program, serious carry out. Need learns and domestic and international successful experience is drawn lessons from when the program weaves, take roundabout way less.
4, urgent affairs undertakes plan and be buildinged to the subterranean space of new developed area of government affairs of Hefei city culture. Build system of collective channel of the subterranean traffic system that conforms with international and underground. Subterranean traffic system basically includes: Subterranean stereo traffic, underground jockeys site of commerce of logic of trade of servent of establishment, ground, underground; System of subterranean collective channel includes: Net of net of transmit electricity line, feed pipe net, heat addition canal, telegraphic network, gas canal, build subterranean collective channel to be helpful for maintenance and enlarge look already, avoided to repeat excavate ground again, stop masses opinion firm big " slide fastener road " .
5, when the construction project that examines and approve old the city zone, should be the development obligate of urban underground space is empty henceforth. Subterranean space is cannot reborn resource, when construction uses sell one's own things, use ratio of volume of ground property, grade, building to wait except the regulation beyond, raise opinion and limitative requirement to subterranean space development even, if restrict a building to use deepness to subterranean space development, the subterranean space that is urban commonweal sex develops obligate space, avoid occurrence Hefei city to need builds subway liaison man and do not have situation of subterranean space awkwardness.
6, the development that runs mode to advance space of Hefei city underground with what commercialize. Urban underground space is extremely precious cannot reborn resource, no matter be collective channel of the subway traffic of commonweal sex, underground, still be storehouse of bazaar of subterranean parking lot, underground, underground the development that wait has taller economic benefits. Exploration builds the use cost of subterranean space, those who build subterranean space is paid development uses a mechanism, execute subterranean space development, land to develop capital operation system, subterranean space development can develop integral sell one's own things with land natural resources, OK also and alone sell one's own things, the means that can use BOT to commonweal sex project undertakes enrolling business.
7, the scientific research that strengthens subterranean space development to use. Establish an expert to seek advice from a system, begin subterranean space to develop the cooperation of science and technology that use and communication, discuss the issue such as program of urban underground space, reconnaissance, design jointly, solve the academic problem that space of Hefei city underground develops, raise construction technology level.
