Description

Porous communication protecting pipe

The utility model relates to a kind of protecting pipe that is used to lay communications optical cable, is a kind of structural improvement to direct burial underground communication optical cable protecting casing.

The utility model patent (patent No. 96229996.0) of by name " Multichannel pipe core ", provide a kind of in the stem stem of the on-circular cross-section in a plurality of optical cables duct, make laying of optical cable comparatively compact, it is more convenient construct, and when directly buried installation, reduces the earth volume of excavation.Increase manufacture difficulty and unnecessary wall thickness consumption of raw material too much but it also exists wall unevenness, increased defectives such as cost and product deadweight.

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can not only simplify mould and production equipment, and can also reduce the porous communication protecting pipe of the moving resistance reduction project total cost in the optical cable laying process.

Another purpose of the present utility model provides a kind ofly lays conveniently, and mounting or dismounting are convenient, the porous communication protecting pipe that structure is comparatively compact, succinct.

Major scheme of the present utility model is: piping is surrounded by one group of planomural and constitutes in described; Inboard adjacent planomural of pipe is parallel to each other in several; The outside planomural of interior pipe is by the coating of linking closely of corresponding polygon outer tube.The interior pipe or the outer tube of Gou Chenging can be regular polygon thus, also can be non-regular polygon.

In order to make uniformly-spaced parallel each other distribution between the pipe in each that places outer tube that link closely, can in described, be provided with one or more along muscle between the distribution of pipe range direction in the planomural outside of pipe, and the planomural of interband muscle is flat on the limit wall of adjacent interior pipe.Also can in described, manage be respectively equipped with on two adjacent planomurals one or more between muscle, and the planomural of interband muscle be flat on respectively adjacent on the planomural of pipe.When a muscle was one, its outer face was to be advisable in the plane of certain width.When a muscle was two or more, each muscle end face height equated to be advisable.Usually, the cross section of muscle can be triangular in shape, trapezoidal between pipe, its outer rim such as rectangular toothed can be curved in described, and the height of a muscle equates with the wall thickness of outer tube; And it is protruding to be provided with the location on an outer side edges of described outer tube.

For the space between pipe in airtight, and make protecting pipe neat and artistic, the interior pipe in described porous communication protecting pipe end slightly stretches out in the end face of outer tube, and removes muscle at interval on the planomural of inner tube portion, and its overcoat has installed capping; Described capping system is made of hole inner edge and the interior pipe outer rim shrouding of joining and cavity inner edge and the outer tube outer rim lid of joining that is nested that is nested.

Connect the body that overlaps an end and be connected with being located in the end of described porous communication protecting pipe; The middle part that connects cover is provided with a back-up ring, and its inner rim is lower than the inner edge of pipe in the outside, is provided with and the porous body that protecting pipe matches of communicating by letter at an end that connects cover.In addition, above-mentioned division board also can be provided with the dividing plate of through hole in the middle part, and the shape of its through hole, hole count are identical with interior pipe, and is slightly larger than the inner edge of interior pipe; Be provided with the body that the protecting pipe of communicating by letter with porous matches at an end that connects cover.

The utility model mainly contains the advantage of following several respects: the one, because interior pipe and outer tube split manufacturing, can simplify the production mould greatly, the input of production equipment and maintenance, the update cost of equipment have been reduced, reach the combination of adopting different color and lusters, different materials pipe between outer tube in also being beneficial between pipe, to reach effect attractive in appearance, economic, practical.The 2nd, by the interior pipe that planomural constitutes, when laying optical cable in its pipe, optical cable is line with planomural and contacts, therefore, can obviously reduce and wear the resistance that moves optical cable, suitably increase the length that the direct-burried sheath lays, reduce manhole or the inspection-pit of building optical cable, reduce the total cost of engineering.The 3rd, the location that muscle and money sleeve pipe place are provided with between the outer setting of interior pipe is protruding, makes the utility model sleeve pipe when directly buried installation convenient, and accurately, firmly, the body outward appearance is neat and artistic, and the space in the end between pipe is airtight, and is smooth.

Below by embodiment, and the contrast accompanying drawing, the utility model is further described.Have in the accompanying drawing:

Embodiment 1: the interior pipe 2 of porous communication protecting pipe is to be the regular hexagon plastic tube by the cross section that five planomurals 20 constitute, and the outside of one planomural 20 is provided with muscle 21 between two, and its height equates with the thickness of planomural 20.Then with four same materials, the hexagon plastic inner pipe 2 of different color and lusters is pressed accompanying drawing 3 and is arranged, promptly on the planomural 20 between muscle 21 be flat on adjacent on the planomural of pipe 2, arrange in the form of a ring successively.Be overmolding to one by going corresponding four jiaos quadrilateral outer tube 3 that pipe 2 in four is linked closely again.And protruding 33 in one of outer tube 3 top-right arranged outside location, so that the direct-burried sleeve pipe when installing, makes positions that pipe 2 is provided with in each can not dock mistake.

During installation, only need to brush one deck plastic adhesive in outer tube 3 peripheries of the utility model end, and will locate protruding 33 locating slots of aiming on the body 51 connect cover 5 one ends 43, and will connect cover 5 and be pressed into, make the end face pressing mutually of side and outer tube 3 of a back-up ring 52 of centre located therein.Equally, connect cover 5 other end body 51 and compress also bonding being integral mutually with the outer tube 3 of another root protecting pipe 1.So lay direct-burried communication protecting pipe to end and the termination outer tube of its end can be removed about 1 centimetre, and remove inner tube portion extension between muscle 21, after plastic adhesive is coated in the end, the lid 42 of capping 4 tightly is enclosed within on the end of outer tube 3, its shrouding 41 removes reserves the place, end that four through holes 40 tightly are enclosed within interior pipe 2, has sealed all spaces of protecting pipe 1 end.

Manage 2 in the regular hexagon that 2: three of embodiment are made of six equal planomurals, its planomural that is provided with a muscle 21 places on the inboard planomural of adjacent interior pipe, three inboard Y-shaped distributions of planomural of pipe in three, the planomural in the outside is covered by the wall body hard-pressed bale of orthohexagonal outer tube 3 and is integral.Pipe 2 and 3 of outer tubes leave the space 9 (referring to accompanying drawing 4) that three cross sections assume diamond in shape in three.Meet cover 5, all the other structures such as capping 4 and installation, laying method and embodiment 1 mutually roughly the same, be omitted.

Embodiment 3: be distributed with muscle 21 between two along the pipe range direction respectively on interior pipe 2 adjacent two planomurals, and six planomurals 20 are not all established a muscle 21 and in the regular hexagon that constitutes pipe 20 bags put in central authorities' (referring to accompanying drawing 5), and above-mentioned seven interior pipes are overmolding to one by orthohexagonal outer tube 3, leave the space 9 that six cross sections assume diamond in shape therebetween.It is protruding 33 that outer tube 3 outside on one side is provided with a location, it is outer can sheathedly be nested with it join connect cover 5 or capping 4.The structure of all the other each parts is identical with embodiment 1, is omitted.
