Description

A kind of information access intensivism building 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 reassemble into telecommunications, move, after the how tame information operator such as UNICOM, add units such as radio and television and digital broadband service, the information service industry of China is in the intense market competition state, 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 strengthen the management of this respect for this reason, launch respectively relevant rules and set up independently management mode and the pipeline laying that information pipeline construction enterprises also carry out " unified planning; the unified construction; unified management " and carry out 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 problem that also has at present two aspects, the one, though organization and construction mode are new, but technical scheme is still reasonable inadequately, the information pipeline that cast and tubing still adopt the man information of list operator to continue to use, it is the plastic film capicitor of small-bore (general diameter is 100 millimeters) on the major trunk roads, walled tube, antipriming pipe and jaywalk and the steel pipe of crossing the river span river, mould compo pipe etc., this pipeline that just each information operator is laid separately is the building method of simple set quantitatively, its construction investment is big, the pore utilance is low, waste greatlyyer, do not embody the advantage 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 a 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, at any time penetrate corresponding plastics pipe according at that time consumption demand in the heavy caliber underground piping, provide the good cable environment of wearing with this, this method has following advantage:

1, the price in the small-bore pipe combination more identical than One's name is legion material of next large-diameter pipe of pipeline section same case is more cheap, therefore can reduce gross investment.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: the major trunk roads design designs the pore with φ 250mm with φ 300mm pore, subsidiary road, 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 method of the present invention, mainly form by six aspect contents:

1, the underground piping of information operator is perfunctory to and is adopted the alternative numerous 100 millimeters small-bore pipe groups of diameter of a large diameter pipeline to close, and reduces the pipeline cost.

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 penetrated, a subsidiary simultaneously isometric nylon rope or steel wire were used for the direct tractive of next second son pipe, just needn't use threader again when wearing the son pipe so next time, and saved original elder generation and " draw " the back one procedure of " the drawing " in " leading ".

4, the sub-pipe of having worn in the big deferent of plastics is tightened up stretching and is fixed in the large 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%).Penetrate the way of pipeline so needn't adopt again simultaneously after all can must being worn son pipe bundling, but adopt ", wear one " according to the actual requirements with 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.Belonging to telecommunications as Fig. 9 neutron tube 2-1 is that white, position are by the most left; The 2-2 of Netcom is that yellow, position are by a middle left side; The 2-3 of UNICOM is that green, position are placed in the middle; Mobile 2-4 is that blue look, position are by the middle right side; Broadcasting and TV 2-5 is red, position by the rightest or the like.

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

Draw bar can draw single stand pipe and penetrate large pipeline, when it connects with son pipe loading and unloading very convenient, when especially in big pore, wearing last a few stand pipe, can in small space, guide son to manage smooth and easy passing.

The effect of tight pipe machine is that the child pipe that will put in the large pipeline is progressively strained, and when manpower is difficult arm is strained when stretching, and it can bring into play useful effect.

The effect of fixture is to use the son pipe to 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.

Its economic benefit of information access intensivism building method of the present invention is very remarkable, and existing is that example is calculated analysis to suppose that each information operator lays 100 millimeters pipelines of eight diameters 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 DN100 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 at major trunk roads with a φ 300mm internal diameter PVC bellows, 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 acceptance procedures cancel all 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:

Fig. 1 is the nest of tubes structural representation before improving, and generally is made up of pipe 1 and wherein child pipe 2 and antipriming pipe 3.

Fig. 2 generally is made up of heavy caliber pipe 4 and son pipe 2 for improving back pipeline configuration schematic diagram.

Fig. 9 is pipe inner structure and subregion schematic diagram after improving, is made up of son pipe cohort in the large pipeline, and 2-1,2-2,2-3,2-4,2-5 represent the child pipe cohort under five information operators respectively, and the outer thick lines of each cohort are the bundling scope.

Fig. 3 is son pipe two ends fixing means schematic diagrames, and anchor ear 5 bundle pipes 2 clamp and rest outside the crosspiece 6 that is close to large pipeline 4 outsides, thereby every stand pipe is fixed on the large pipeline two ends.

Fig. 4 is the structure chart of draw bar.Draw bar is by pull bar 7, tense-lax nut 8, expansion sleeve 9, pull-off spring 10, hexagon socket head cap screw 11, vertebra post 12 are formed, when draw bar inserted sub-pipe port, rotation tense-lax nut 8, vertebra post 12 expanded expansion sleeve 9, the child pipe is tightly blocked, draw sub-pipe and penetrate pipeline, after the group pipe passes pipeline, as long as reverse rotation tense-lax nut 8, expansion sleeve 9 shrinks voluntarily, thereby draw bar is easily taken out in the child pipe.

Fig. 5 is the structure chart of tight pipe machine.Tight pipe machine is made up of lever 13, base 14 spring leafs 16, movable sleeve 17, fixed cover 18.Stir movable sleeve 17 by lever 13 during operation and do outwards motion, the spring leaf 16 in its cover is clamped also outwards motion of son pipe 2, and when movable sleeve 17 transport constantly inwards, spring leaf can not be clamped son pipe 2 motion inwards, because the spring leaf that overlaps in 18 that is fixed blocks.Son pipe 2 can only outwards be done one-way movement when movable sleeve 17 reciprocating motions like this, thereby the bundle pipe is progressively strained.

Fig. 6, Fig. 7, Fig. 8 are fixture structure figure.Fixture is made up of crosspiece 6, anchor ear 5 or spring clip 19.During use crosspiece 6 horizontal large pipeline end face, bundle pipe 2 usefulness anchor ears 5 or the spring clips 19 of resting are tightly clamped and are laid on outside the crosspiece 6, the every stand pipe 2 in the pipeline just is fixed on the large pipeline two ends by crosspiece 6 and anchor ear 5 or spring clip 19 like this.

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.
