Description
Technical field
The present invention relates to architecture information science and Geographical Information Sciences field, more particularly to the ground based on BIM and big data
The modeling method of lower pipe gallery.
Background technique
It is well known that daily life, commercial office, social activities etc. all be unable to do without " water, electricity and gas ", especially resident is daily
Life is even more closely bound up with " water, electricity and gas ".Herein, " water, electricity and gas " inner " water " generally comprises water supply and draining two parts, point
It Tong Guo not feed pipe and drainpipe transport；" water, electricity and gas " inner " electricity " generally refers to electric power, often through power pipeline and electric power
Pipeline, which is given, to be conveyed；" water, electricity and gas " inner " gas " generally refers to combustion gas, often by natural gas line and other gas pipelines
It gives and conveys.Since mankind's urban development, the pipeline of these " water, electricity and gas " is just embedded in the underground in city, serves city
Each region.
It is worth noting that, causing the above as the fast development of urban economy and the swift and violent of urban population are incremented by
The management of " water, electricity and gas " is increasingly difficult with O&M, is typically include: the surge of user results in the need for original pipeline appearance in building
The expansion of amount, road to be not intended to dig all kinds of pipe layings, various types pipeline under broken road while overhauling spatially interleaved curved
Qu Zaocheng can not be recognized etc., and similar above-mentioned phenomenon emerges one after another, and especially the central area problem in urban area is especially bright
It is aobvious, it makes troubles for municipal administration and resident's daily life, or even cause safety accident and (dug when the typical finishing such as road broken natural
Feed channel).
In face of problem above, the more early Consciousness Problem of all kinds of developed countries and regions simultaneously sets about solving the problem, typical to propose
The concept and mentality of designing of " pipe gallery (also referred to as common trench) ", core are that above all kinds of " water, electricity and gas " management is unified
Be contained in after an integration within piping lane (pipe gallery is largely embedded in underground, so below also referred to as by underground pipe gallery
Pipe gallery), as shown in Fig. 1 (a) to Fig. 1 (e), Kaiser-Wilhem of such as 1893 former Germany in hamburger city of preceding West Germany
Pipe gallery receiving steam heating pipe, running water pipe, electric power, optic telecommunications cables and the gas pipe of 450 meters of construction below the pavement of street two sides,
But be free of sewer；Britain builds pipe gallery in London urban district in 1861 to accommodate running water pipe, sewage pipe and gas
Pipe, electric power, telecommunications；Paris, FRA starting is early and has nowadays built up the more perfect common trench of about 100 kilometers of total length, system
Network；Japanese nineteen twenty-six starts the common trench built underground common trench and possessed about 310 kilometers of length at present；In China,
Pipe gallery is started late.Pipe gallery gives integrated management and the maintenance base of above all kinds of " water, electricity and gas " pipelines and pipeline
Plinth greatly reduces the management difficulty of municipal pipeline and pipeline, as shown in Fig. 2 (a) to Fig. 2 (c).The phase of underground pipe gallery
It is as shown in Figure 3 to close laws and regulations.
As described above, the construction of pipe gallery, greatly reduces the management difficulty of municipal pipeline and pipeline, but also big simultaneously
The construction cost of municipal pipeline is increased greatly.According to statistics, Japan, the Taibei of TaiWan, China, Shanghai pipe gallery be averaged cost
(calculating according to RMB) is 500,000 yuan/meter respectively, 130,000 yuan/meter, (if counted according to kilometer, every kilometer is made 100,000 yuan/meter
Valence more than one hundred million members at least), it is high compared with common pipelined fashion cost.In face of so high construction cost, using software
Giving informationization is conventional thinking, and is low-down (with a city more than ten for the IT application cost ratio of pipe gallery
For the pipe gallery construction of kilometer, overall cost needs more than ten00000000 yuan at least, and information-based cost is often total not as good as above
The 1% of body expense), so the informationization for giving pipe gallery is trend of the times.
The construction of pipe gallery and maintenance belong to urban operating mechanism (core i.e. municipal pipeline and pipeline, with road traffic etc.
It is closely related) range of management, it is closely bound up with architecture, typically information process- can be given using the method for BIM.
BIM is generally translated as " modeling information model (Building Information Model) " or " architecture information
It models (Building Information Modeling) ".BIM is a complete information model, and engineering project can exist
The engineering information of each different phase, process, resources integration are easily respectively joined by engineering in a model in Life cycle
With square use；By real information possessed by 3-dimensional digital technical modelling building, provided mutually for engineering design and construction
Coordinate, internally consistent information model, so that the model is reached the integration of design and construction, each profession cooperates, to reduce
Engineering production cost ensures that engineering on time presses matter completion.For BIM, IFC (Industry Foundation Classes,
Industrial foundation class) it is the specific format standard for being widely recognized as and being received in the world.It, can later for the elaboration of IFC
It is described in detail.
While it is noted that can see by the above concept of " pipe gallery ", pipe gallery is by running water pipe, day
All kinds of " water, electricity and gas " pipelines such as right tracheae, feed pipe, drainpipe and pipeline integration ground construction (construction), management
(management), (maintenance) is safeguarded, the information being related to is flood tide compared with original processing respectively.So relating to
And collection, analysis, the processing of mass data and information, it is closely related with " big data ".For big data (Big Data), refer to
The data acquisition system that can not be captured, manage, be handled with conventional software tool within certain time is to need new processing mould
Formula could have stronger decision, see clearly discovery power, the magnanimity of process optimization ability, high growth rate, diversified information assets.
