Description

Information access intensivism building new method

One, technical field:

The invention belongs to the information infrastructure building field, is a kind of improvement to existing information (communication, broadcasting and TV, digital broadband etc.) underground piping intensive construction technology.

Two, background technology:

Since China Telecom splits and set up into telecommunications, move, UNICOM, Tie Tong, Netcom, defend logical, after the how tame information operator such as Jitong, add units such as radio and television and digital broadband service, the information service industry of China is in the intense market competition state of feudal lords vyiying for the throne, foundation works as information service industry, therefore be that laying of information pipeline is professional occurs fighting separately and the situation of unordered confusion, some city managers with foresight determine to strengthen the management of this respect for this reason, launch respectively related regulations and policies and set up the management mode of independently also implementation of information pipeline construction enterprises " unified planning; the unified construction; unified management " and the technical scheme of " being total to well " with ditch, the construction mode of promptly so-called " intensification ", the practice through has in a few years obtained certain economic benefits and social benefit.

Yet, the present problem that also has two aspects.The one, though organization and construction mode are new, but technical scheme is still reasonable inadequately, it is the information pipeline that cast and tubing still adopt the man information of original list operator to continue to use, be small-bore plastic film capicitor, walled tube, antipriming pipe and jaywalk on the major trunk roads and the little steel pipe of crossing the river span river, mould compo pipe etc., this pipeline that just each information operator was laid separately originally is the building method of simple set quantitatively, its construction investment is big, the pore utilance is low, waste is bigger, does not embody the advantage (seeing Fig. 1 for details) of intensive construction fully.The 2nd, when implementing intensive construction in development zone newly developed, because chronic between the pipeline of roughing-in and use, therefore the investment recovery is slow, investment risk is big, each information operator construction enthusiasm is not high, often miss the good opportunity that underground piping and synchronous road are built, thereby increased the cost of later construction greatly.As investing by country or investment enterprise, also exist investment risk to reach the pore number greatly and be difficult to problems such as design prediction etc., for this reason, be necessary original technical scheme is introspected and improved.By analysis, the purpose of laying the subsurface information pipeline is nothing but two, the one, " occupying the underground space ", the 2nd, " provide and wear the cable environment ", the two was realized simultaneously originally, so investment is very big.Now in order to reduce investment, use " occupying the underground space " instead and go on foot the way of walking with " provide and wear the cable environment " two, promptly when road construction, lay large diameter pipeline cheaply earlier, at first occupy road underground space, then when information user's demand having been arranged cloth given out light () cable immediately, in the heavy caliber underground piping, penetrate corresponding plastics pipe at any time, provide the good cable environment of wearing with this according at that time consumption demand.This is a new technical scheme, and this scheme has following advantage:

1, comparatively more cheap at next bigbore plastic tube of cross section same case than the package price of the small-bore plastic tube of One's name is legion, therefore can reduce gross investment (seeing Fig. 1, Fig. 2 for details).As further on material, improving, adopt the heavy caliber pipe of cement to substitute original moulding pipe, steel pipe and mould compo pipe, then more will reduce the pipeline cost exponentially.

2, the bigger pore number design prediction of difficulty has been become the design of large pipeline total sectional area, the forecasting problem that can thick lines ground solves the pipeline number, such as: major trunk roads design φ 300mm pore, subsidiary road design φ 250mm pore, branch road design φ 200mm pore or the like, so just needn't too move the suggestion of asking each information operator, regain the initiative.

3, employing is worn plastics pipe before wearing light () cable, promptly according to the actual requirements " with one, wear one " or " with several, wear several " method, though changed original only with a stand pipe but want four ways that penetrate φ 100mm pipe together, thereby significantly reduce idle child pipe quantity and reduce initial investment, its key be solved since sub-pipe crooked in large pipeline, twine and can not a problem that penetrate.

4, owing to having only a large pipeline, so in each link such as construction, examination, maintenance, all can save a large amount of expenses.

Three, summary of the invention:

Information access intensivism building new method of the present invention, mainly form by six aspect contents:

1, the underground piping of all information operators lays employing " same pipe, Tong Gou, Tong Jing " " three together " principle, substitutes numerous small-bore pipe groups with large diameter pipeline and closes, and reduces the cost of pipeline.

2, on pipe material, the both available material identical with small-bore pipeline, more available heavy caliber pipe of cement substitutes and to cross and the steel pipe of cross a river, mould compo pipe, reach the pipe of moulding on the arterial highway, so both increased the compression strength of pipeline, but anticorrosion again, anti-aging, antitheft more can reduce the pipeline cost at double.The heavy caliber pipe of cement is compared with the honeycombed cement pipe of once using in early days, and price advantage still obviously exists, and constructs, safeguards more convenient.

When 3, each sub-pipe penetrates, subsidiaryly simultaneously penetrate an isometric nylon rope or steel wire, be used for the direct tractive of next second son pipe, just needn't again use threader when wearing the son pipe so next time, and save original elder generation and " draw " the back one procedure of " the drawing " in " leading ".

4, the sub-pipe of the plastics of having worn in the large pipeline is tightened up stretching and is fixed in the pipeline, therefore this a little Guan Buhui natural torsion, winding mutually in pipeline, sub-pipe does not penetrate after can not influencing, and finally can penetrate as much as possible, make the engineering whole economic efficiency reach maximization (through practice, the maximum reality of son pipe can penetrate number for theoretical value about 70%).Originally must all can be worn the way that penetrates pipeline behind the son pipe bundling more simultaneously so needn't adopt, but employing according to the actual requirements " with one, wear one " or " with several, wear several " way, to reduce the idle quantity and the initial investment of sub-pipe.

Along with the stretching and fixing arm of tension progressively increases, it is no longer crooked that the face pipe will be piled up and push down down to the child pipe on upper strata and light () cable, at this moment, looks concrete condition and following sub-pipe fixing device can be removed, to reduce expenses and space resources.

5, the plastics pipe to having penetrated in the large pipeline, adopt horizontal level partition and color classification way of combining, the child pipe that is same information operator is tried one's best between vertical distribution, each operator according to the horizontal direction partition, and at child pipe two ends together, divide, define child pipe under each information operator with this identical child pipe bundling of color.Be white, position keep left (1) such as telecommunications; Netcom is yellow, position keep left (2); UNICOM is green, position (3) placed in the middle; Move and to be blue look, position keep right (4); Broadcasting and TV are red, position keep right (5) or the like.(seeing Fig. 2 for details)

6, the penetrating, strain and fixing can use specific purpose tool to increase work efficiency of sub-pipe mainly contains " draw bar ", " tightly managing machine " reaches " fixture ".

" draw bar " can draw single stand pipe and pass underground pore, when it connects with son pipe loading and unloading very convenient, when especially in big pore, wearing last a few stand pipe, can guide in small space that arm is smooth and easy to be passed.(seeing Fig. 4 for details)

The effect of " tightly managing machine " is that the child pipe that will put in large pipeline is progressively strained, and when manpower is difficult arm is strained when stretching, and it can bring into play useful effect.(seeing Fig. 5 for details)

The effect of " fixture " is to make the son pipe keep the stretching state of tension always, avoids producing natural torsion and winding in pipeline, guarantees when other sub-pipe will penetrate from now on unblocked.(seeing Fig. 3, Fig. 6,7,8 for details)

Its economic benefit of information access intensivism building new method of the present invention is very remarkable, and existing is that example is calculated analysis to suppose that each information operator lays eight branch pipe(tube)s altogether:

1, during the jaywalk of information pipeline, add the cement total incapsulation with a φ 300mm internal diameter pipe of cement and substitute eight DN100mm steel pipe cohorts, its pipeline cost can descend 5/6.

2, the information pipeline crosses the river when striding the river, substitutes eight DN100mm steel pipe cohorts with a φ 300mm internal diameter steel pipe, and under the close situation of wall thickness, its pipeline cost can descend 1/2.

3, substitute eight PE φ 102mm pipe cohorts with a φ 300mm internal diameter PVC bellows on major trunk roads, its pipeline cost can descend 1/2.

4, because the underground piping number changes one into by eight, therefore easy construction reduces labour cost, but the logical cancel all of checking and accepting of the examination of complexity during final acceptance of construction, pipe-line maintenance does not from now on simultaneously also exist every branch pipe(tube) to carry out periodic flushing and examination is logical, reduce maintenance cost, three additions can reduce expense about 10% at least.

Four, description of drawings:

Five, embodiment:

1, need lay type and about quantity of light () cable on this road according to each information operator, the external diameter of determinant pipe and quantity are leaving the internal diameter that estimates the large pipeline that need lay under the suitable headspace situation.

2, according to road and the route of pipe line by actual conditions, the material and the model of decision large pipeline.

3, finish the construction drawing design.

4, buying tubing and accessory, organizing construction and final acceptance of construction.

5, estimate according to the traffic carrying capacity of each information operator, the distributed areas of big pore cross section neutron tube are made rational planning for, divided, and each information operator pairing son pipe color is stipulated.

6, according to the give out light demand of () cable of each information operator cloth, model, color and the quantity of the sub-pipe of decision plastics.

7, according to the zone of dividing and the color of sub-pipe, the child pipe is penetrated in the big pore by propping up, at one end use under " fixture " fixing situation, with " tightly managing machine " other end is strained, and it is fastening with another pair " fixture ", make each the stand Guan Jun that has put on be in the stretching state of tension, the usefulness that supplies each information operator to wear light () cable.When last straton pipe and optical cable guarantee all to push down down the face pipe, when making it not recover bending again, look concrete condition and following " fixture " can be removed.

8, as required, the operation of son pipe be can wear at any time, subsidiary simultaneously penetrate a nylon rope or steel wire needed when each sub-pipe penetrates.

9, in inspection shaft large pipeline exit, the son pipe port of export of wearing close the position, that color is identical ties together, and the affiliated child pipe of each information operator is come into plain view.
