Description

A kind of communication microchannel of non-excavation micro-control push pipe formula construction

Technical field

The utility model relates to a kind of communication microchannel of non-excavation micro-control push pipe formula construction, belongs to technical field of cable transmission.

Background technique

Generally speaking, the system of laying of telecommunication cable has three kinds: underground cable, overhead cable and buried cable.In the urban district,, generally do not adopt buried cable owing to ditching disturbs residents and reason such as urban planning.Traditional scheme is to build jumbo main conduit on the trunk main road, lays main cable.And numerous distribution cable, many employings are built on stilts lays, to reduce investment outlay.Adopt the then variation of situation generation essence of optical cable, as the optical cable frame aloft, external condition is extremely unstable, and optical index changes easily, the bit error rate height that information is propagated.Therefore, consider that as aspect such as hack at the branch optical cable all should be laid in the communication pipe from safe and reliable, transmission performance, cable life and the maintenance workload of circuit.And " overhead line is gone into ground " also is the effective measures that change appearance of city.

The traditional communication pipeline is based on tubing such as cement block, the double-wall corrugated formula plastic tubes of single hole, and the aperture is more single, mostly is φ 90mm greatly.For satisfying the usefulness of laying big logarithm light () cable, along with the demand of optical cable, laid a spot of seven apertures in the human head plum blossom pipeline, wear and put ordinary optical cable.But the traditional communication pipeline takies a large amount of underground resources, and the earth excavation amount is big, long construction period, and the fiber channel that provides is few, the comprehensive cost height.

Summary of the invention

The purpose of this utility model is the communication microchannel that proposes a kind of non-excavation micro-control push pipe formula construction, taking underground resources less as far as possible, and obtains a large amount of fiber channels.

The communication microchannel of the non-excavation micro-control push pipe formula construction that the utility model proposes, comprise bundling strap, optical cable pipe and microtubule, the sub-pipe of described optical cable has 1～7, the many sub-pipes of optical cable are tied into a branch of by bundling strap, described microtubule places the sub-pipe of optical cable, and the microtubule in every sub-pipe of optical cable has 4～6.

Above-mentioned communication microchannel also comprises optical cable pipe, and the sub-pipe of described optical cable places colligation to become the central authorities of a branch of communication microchannel.

The advantage of the communication microchannel of the non-excavation micro-control push pipe formula construction that the utility model proposes is:

1,, obtains a large amount of fiber channels with a spot of underground resources.

2, form of construction work is flexible, short construction period, and comprehensive cost is low.

3, can provide bigger elasticity dilatation ability, satisfy the sudden demand of city broadband services greatly optical fiber.

4, save great deal of raw materials.Satisfy same message capacity, save material more than 70% than the construction mode of existing communication pipeline.

Description of drawings

Fig. 1 is the structural representation of the communication microchannel that the utility model proposes.

Fig. 2～Fig. 4 is three different embodiments of the communication microchannel that the utility model proposes.

Among Fig. 1～Fig. 4, the 1st, bundling strap, the 2nd, optical cable pipe, the 3rd, standby optical cable pipe, the 4th, microtubule.

Embodiment

The communication microchannel of the non-excavation micro-control push pipe formula construction that the utility model proposes, its structure comprise bundling strap 1, optical cable pipe 2 and microtubule 4 as shown in Figure 1.Optical cable pipe 2 has 1～7, and many optical cable pipes 2 are tied into a branch of by bundling strap 1.Microtubule 4 places optical cable pipe 2, and the microtubule in every sub-pipe of optical cable has 4～6.In the communication microchannel shown in Figure 2, the sub-pipe of optical cable has 7, and wherein the sub-pipe of optical cable places central authorities, around all the other 6 sub-pipes of optical cable place, ties up into bundling strap and to become rock-steady structure after a branch of.

Above-mentioned communication microchannel also comprises optical cable pipe 3, its structure as shown in Figure 3, optical cable pipe 3 places colligation to become the central authorities of a branch of communication microchannel.

3 or 4 communication microchannels by the colligation bunchy that the utility model proposes can also be installed in female pipe (not shown), as shown in Figure 4, to improve message capacity greatly.

The communication microchannel that the utility model proposes can be used for fiber channel between residence network, the Nei Lou of community and the building.Make up the used son pipe of novel communication microchannel and be HDPE plastics pipe, specification is two kinds of φ 60/50mm (being called optical cable pipe) and φ 40/33mm (being called optical cable manages).The microtubule that can lay in the optical cable pipe is φ 12/10mm microtubule, φ 10/8mm microtubule, φ 7/5.5mm microtubule.The material of group's band is a nylon band, and its thickness is not less than 1mm, and width is not less than 3mm.Can manually penetrate 3 φ 12/10mm microtubules in the optical cable pipe, or 5 φ 10/8mm microtubules, or 8 φ 7/5.5mm microtubules.Can manually penetrate 0.4 line footpath 600 pairs and following HYA speech cable in the optical cable pipe.
