Abstract
The utility model relates to a PE protecting pipe provided with a metal part and belongs to the technical field of plastic processing of PE protecting pipes. The PE protecting pipe provided with the metal part is composed of a protecting pipe plastic outer layer and a protecting pipe plastic inner layer. The inner wall of the protecting pipe plastic inner layer is provided with axial air guide grooves distributed uniformly. More or more copper wires are arranged in the protecting pipe plastic outer layer in the axial direction. The cross section of each copper wire is round-shaped. The section of the air guide groove is trapezoid-shaped or rectangular. According to the utility model, the copper wires are disposed in the protecting sheath plastic outer layer in the axial direction. Location of the protecting sheath can be detected accurately by utilizing a metal detector and the copper wires in the protecting pipe in later maintenance and upgrading process, so that a problem of resource waste that optical cable protecting pipe is easy to damage when being taken out since specific position and accurate extending direction of the optical cable protecting pipe are not known in later maintenance and upgrading process after prior protecting pipe wire arrangement construction. And the PE protecting pipe provided with the metal part is simple in structure, easy to produce and manufacture and low in manufacture cost.
Description
Technical field
The utility model relates to a kind of PE protecting pipe with metal of the use of communicating by letter, and belongs to the technical field of plastic of PE protecting pipe.
Background technology
The application of optical cable in existing communication network is very extensive, but because the intensity of optical cable itself is poor, generally all to adopt optical cable outward in addition plastic protecting casing protect.Plastic protecting casing installs additional when optical cable cable wiring manufacture, first plastic protecting casing is embedded in undergroundly, and then in protecting pipe the inside, wears the cable of giving out light.Due to protecting pipe be directly embedded in underground; so; in optical cable afterwards and protecting pipe maintenance upgrade process; often there will be and do not know the particular location of optical cable protecting casing and bearing of trend accurately; cause excavating while taking out optical cable protecting casing easily to its damage; inefficiency, manpower and material resources are wasted the situations such as large, have increased cost and the difficulty safeguarded.
Summary of the invention
The purpose of this utility model is, a kind of metal copper wire of placing in PE protecting pipe extrusion is provided, with the same one-step extrusion molding of protecting pipe, metal copper wire is all overlying in the plastic material of protecting pipe, form an integral body with protecting pipe, in maintenance upgrade process afterwards, utilize metal detector to survey the PE protecting pipe with metal that copper wire in protecting pipe can be determined protecting pipe accurate location.
The utility model is to realize by the following technical solutions above-mentioned purpose:
This PE protecting pipe with metal consists of protecting pipe plastic outer layer and protecting pipe inner plastic, protecting pipe inner plastic is placed on the inwall of protecting pipe plastic outer layer, it is characterized in that: on the inwall of protecting pipe inner plastic, be manufactured with uniform axial air slot, in protecting pipe plastic outer layer, along axis direction, be placed with one or more copper wire.The section configuration of described copper wire is circular, and brass wire diameter is Φ 0.4～0.5mm.The section configuration of described air slot is trapezoidal or rectangle.
The utility model beneficial effect is compared with prior art:
This PE protecting pipe with metal is placed with copper wire along axis direction in protecting pipe plastic outer layer, in maintenance upgrade process afterwards, utilize copper wire in metal detector and protecting pipe can accurately detect the orientation of protecting pipe, thoroughly solved after existing sheath tubing cable wiring manufacture in maintenance upgrade process afterwards, do not know the particular location of optical cable protecting casing and bearing of trend accurately, cause excavating while taking out optical cable protecting casing easily to its damage, inefficiency, manpower and material resources are wasted large problem.And simple in structure, manufacture easily low cost of manufacture.
Accompanying drawing explanation
Accompanying drawing is a kind of section structure schematic diagram of the PE protecting pipe with metal.
In figure: 1, protecting pipe plastic outer layer, 2, protecting pipe inner plastic, 3, copper wire, 4, air slot.
Embodiment
This PE protecting pipe with metal consists of protecting pipe plastic outer layer 1 and protecting pipe inner plastic 2, protecting pipe inner plastic 2 is placed on the inwall of protecting pipe plastic outer layer 1, on the inwall of protecting pipe inner plastic 2, be manufactured with uniform axial air slot 4, protecting pipe plastic outer layer 1 is interior is placed with one or more copper wire 3 along axis direction, generally places a copper wire 3.The section configuration of described copper wire 3 is circular, and brass wire diameter is Φ 0.4～0.5mm.The section configuration of described air slot 4 is trapezoidal or rectangle, is generally made into trapezoidal (referring to accompanying drawing).
This PE protecting pipe manufacturing process with metal is, by mould mode, in the process of producing in 1 extrusion molding of protecting pipe plastic outer layer, synchronously copper wire 3 is passed to the centre position of die mandrel, then with protecting pipe inner plastic 2, synchronously extrude, 3, copper wire is all overlying on the centre of protecting pipe plastic outer layer 1 firmly, forms an integral body, wherein on the inwall of protecting pipe inner plastic 2, is manufactured with uniform axial air slot 4.Edge forming limit rolling during extrusion molding, is this with the finished product of the PE protecting pipe of metal after blocking according to needed length.
The above is preferred embodiment of the present utility model, above-mentioned not illustrating done any pro forma restriction to flesh and blood of the present utility model, any simple modification or distortion that person of an ordinary skill in the technical field has done above embodiment according to technical spirit of the present utility model after having read this instructions, and the technology contents that may utilize above-mentioned announcement is changed or is modified to the equivalent embodiment of equivalent variations, all still belong in the scope of technical solutions of the utility model, and do not deviate from essence of the present utility model and scope.
Claims (3)
