Abstract

The utility model relates to a warning tracking band for a buried plastic pipeline, which is a marker used when plastic pipelines (such as gas pipelines, running water pipelines, etc.) are buried under the ground. The utility model has a plastic base band; metal foil and a warning mark are arranged on the plastic base band along a long direction. The utility model is covered with a layer of plastic film on the basis of the structure; both sides of the plastic base band along the long direction can be provided with two bars of metal foil in parallel. Thus, the utility model has the original warning function and can be detected by the existing metal pipeline detector which is universally adopted, and accordingly, dual functions of warning and tracking can be realized.

Description

Bury ground plastic conduit caution, warning tracking band

The utility model relates to, and to bury ground plastic conduit caution, warning tracking band be a kind of underground marker that uses when burying plastic conduit (as gas pipeline, water supply pipe etc.) underground that is used for.

At present, the gas transmission and distribution engineering adopts plastic conduit in large quantities, for reducing the artificial destruction of burying ground combustion gas plastic conduit and being convenient to from now on operational management, should lay warning tape and spike line at an upper portion thereof simultaneously when all having stipulated to bury the combustion gas plastic conduit underground in the relevant job specifications of country.Present common practice is: use plain conductor as the spike line, with the plastic film tape that is printed on warning mark as warning tape, because plain conductor still exists some masty problems as warning tracking band on construction method and detection technique, as anticorrosion problem of plain conductor and the higher problem of cost etc., so that people produce query to the reliability of laying the spike line, and then to laying the necessity generation query of spike line, make many construction works in fact not lay spike line (generally all having laid warning tape), this brings inconvenience to the prospecting and the maintenance management of underground plastic tube network from now on undoubtedly.

The purpose of the utility model is to provide a kind of marker that possesses caution and spike dual-use function---and bury ground plastic conduit caution, warning tracking band, can once finish easily when making pipeline construction, reduce finished product simultaneously the requirement of pipeline caution with spike.Further purpose of the present utility model is the usable range for the metallic conduit detection instrument that enlarges the detection underground pipeline that generally adopts at present, and the pipeline that makes it can offer an explanation underground laying is that metallic conduit or plastic conduit provide a kind of possibility.

The technical scheme that adopts that achieves the above object is: this ground plastic conduit caution, the warning tracking band of burying is characterized in that: have the plastics base band; Be provided with metal forming at this plastics base band upper edge length direction, on the plastics base band, also be provided with warning mark.

Also can cover one deck plastic foil above the above-mentioned said metal forming that is covered with metal forming plastics base band makes the metal forming clamping between plastics base band and plastic foil.Above-mentioned said caution, warning tracking band, two strip metal paper tinsels structure also can be made on the plastics base band and be arranged in parallel along the both sides of its length direction.

By technique scheme make bury ground plastic conduit caution, warning tracking band has following advantage: in the both sides of the plastics system warning tape that generally adopts at present compound on the metal forming (as aluminium foil etc.) of certain width, so the marker that forms promptly possesses original warning function, also can be detected, thereby reach the dual-use function of caution, spike by the metallic conduit detection instrument that generally adopts now.And certain width and at a distance of two strip metal paper tinsels of certain distance can provide the reverberation of a pair of rule, for the detector of making special use provides condition; Use this caution, warning tracking band not to change construction method and the custom that has warning tape now, thus simple, and the more existing warning tape of its cost increases few, and is significantly less than the laid down cost of metal spike line; Can have and guarantee the strict execution of standard with putting; For the detection and the maintenance of burying the ground plastic conduit provides convenience in the future.

Fig. 1 is for originally burying the organigram of ground plastic conduit caution, warning tracking band.

Fig. 2 for the A-A of Fig. 1 to cut-open view (having increased plastic foil).

The embodiment that provides below in conjunction with accompanying drawing further describes.As shown in Figure 1 and Figure 2, this caution, warning tracking band include plastics base band (1), metal forming (2), warning mark (3) and plastic foil (4).Wherein plastics base band (1) can adopt commercially available Polypropylence Sheet, film material to get final product; Metal forming (2) can adopt aluminium, copper and other metal species material all can; Warning mark (3) could adopt " gas piping "! Dangerous! Warn, show that Deng what printed words or unification of the motherland standard were used dangerous pattern etc. is printed on gets final product on the plastics base band (1); Plastic foil (4) adopts commercially available plastic film material.The purpose of wherein laying metal forming (2) on plastics base band (1) is spike, effect is the metallic conduit detection instrument that use on ground to be sent detectable signal feedback to detection instrument to show the buried pipeline position, and two parallel metal formings are set can provide the reflected signal of a pair of rule to be different from the metallic conduit feedback signal earthward.Having laid the purpose that applies one deck plastic foil (4) after metal forming (2) and seal are finished warning mark (3) again on the plastics base band (1) is for reducing the oxidation and the corrosion of metal forming (2), certainly, under the situation better at geologic condition, that corrosion is not serious, should also can omit by facial mask for being lowered into, because of on plastics base band (1), lay metal forming (2) can adopt be coated with, seal, normal process now such as compound, be the known technology category, so not superfluous stating.When using this caution, warning tracking band in the construction, can use by the construction method of stipulating in the national corresponding standard to get final product.

Claims

1, a kind of ground plastic conduit caution, warning tracking band of burying is characterized in that: have the plastics base band, be provided with metal forming at this plastics base band upper edge length direction, also be provided with warning mark on the plastics base band.

2, by described ground plastic conduit caution, the warning tracking band of burying of claim 1, it is characterized in that on said metal forming, also can covering one deck plastic foil and make the metal forming clamping between plastics base band and plastic foil.

3, by claim 1 or 2 described ground plastic conduit caution, the warning tracking bands of burying, the base two strip metal paper tinsels that are characterised in that on the plastics base band and can be arranged in parallel along the both sides of its length direction.
