Abstract

A tracing line comprises a conductor and a PE layer; the tracing line is characterized in that the PE layer is wrapped outside the conductor; the tracing line is mainly used for gas, water supply, water drainage and waste water plastic pipe systems; conventional gas, water supply, water drainage and waste water pipes are metal pipes and pipe positions can be directly detected by detecting tools, but metal pipes easily rust and service life of the metal pipes is reduced; so the metal pipe is replaced by plastic pipe, but the plastic pipe is an insulator and cannot be detected by electronic detecting tools, and correct positions of the plastic pipes cannot be learned, thereby bringing troubles for later maintenance or other constructions. The tracing line solves the problem; and the tracing line only needs to be paved along with the gas, water supply, water drainage and waste water plastic pipes, then can be used for detecting plastic pipe positions in a later time, thereby preventing generation of gas leakage or even blast accident caused by that the pipes are broken or damaged by construction machineries.

Description

A kind of spike line

Technical field

The utility model relates to a kind of aid, particularly a kind of spike line for plastic conduit position measurements such as combustion gas, water supply, draining, sewage.

Background technology

Along with the development of society, the raising of people's living standard, the use of combustion gas and water supply are popularized in most of family, and particularly in the city, underground combustion gas, water supply, draining, sewer line are intricate especially.Pipeline in the past is to adopt metal material, and so easy use electronic test equipment is tested the position of current metallic conduit, has avoided some unnecessary potential safety hazards thereby bring convenience for maintenance or construction.Thereby yet because being embedded in underground being corroded easily for a long time, the pipeline of metal material cause piping failure to cause leaking gas or leaking.So not only cause the waste of resource, even bring serious potential safety hazard.So considered the pipework construction of plastic conduit instead of part position, because plastic conduit have construction costs low, be not easy to be corroded, transportation of substances polluted advantages such as little, so plastic conduit is widely used in the urban pipe network construction in recent years, particularly delivery of fuel gas and water supply line are used at most.Yet, because plastic conduit is insulator, can't measure the definite position of pipeline with electronic test equipment, so thereby in work progress just easily by construction machinery dig disconnected, dig and Lou bring unnecessary potential safety hazard.Especially some buried plastic pipes adopt warning tracking band protection pipeline more, and doing like this wastes time and energy also uneconomically, and when the soil layer that is embedded with tracer label is destroyed after, just are difficult to the definite position of definite pipeline, are not easy to keep in repair from now on or other construction.

The utility model content

For overcoming the deficiencies in the prior art, the utility model provides a kind of spike line, can the auxiliary electron testing apparatus measure the pipeline accurate location, brings convenience for from now on maintenance or other construction.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of spike line, comprise electric conductor and PE layer, and wherein: described PE layer is coated on the electric conductor outside.

As further improvement of the utility model: the preferred steel wire of described electric conductor, described electric conductor appearance is coated with the layer of copper layer.

As further improvement of the utility model: described electric conductor can adopt copper product.

Compared with prior art, the beneficial effects of the utility model are: except can subtest equipment surveying the definite position of underground plastic conduit, and bring convenience for from now on maintenance and other construction, and prevent that unnecessary potential safety hazard, bigger characteristics from being the stretching resistance that has promoted a kind of spike line.

Description of drawings

Fig. 1 is the utility model structural drawing;

Fig. 2 is the utility model cross-sectional end view.

Embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

Referring to figs. 1 through 2, a kind of spike line comprises electric conductor 1 and PE layer 2, and wherein: described PE layer 2 is coated on electric conductor 1 outside.The monolateral thickness of wherein said PE layer 2 is 1mm～10mm, has the function of insulation, anticorrosion, waterproof, is equal to plastic conduit serviceable life, and metal material is adopted at the center, splicing thread body tensile strength, and the top layer of plating can strengthen electric conductivity, improves electric signal.

Described electric conductor 1 preferred steel wire, described electric conductor appearance is coated with layer of copper layer 3, because steel matter tensile strength is good, is not easy to be broken when laying.

Described electric conductor 1 can adopt copper product, the copper material good conductivity.

The scope of application of the present utility model is: the excavation pipe laying, horizontal directional drill pass through traction.

Principle of work of the present utility model is: the utility model is laid with combustion gas, water supply, draining, sewage plastic conduit.During detection, add the current signal of certain intensity for the spike line, determine the locus of spike line by the electromagnetic field center of surveying the generation of spike line current, thereby reach the position of determining to be embedded in underground plastic conduit, so that maintenance from now on or other construction, thus prevent combustion gas/water supply, draining, sewer line by construction machinery dig disconnected, dig the generation that the gas leakage explosion accident that causes thus appears avoiding in leakage phenomenon.

In sum, after those of ordinary skill in the art reads the utility model file, according to

The technical solution of the utility model and technical conceive need not creative brainwork and make other various corresponding conversion scheme, all belong to the scope that the utility model is protected.
