Abstract
The utility model discloses a warning marking strap weaved by composite plastics, which is used in urban construction to warn that the gas pipelines and other underground pipelines are laid under the ground. The warning marking strap weaved by composite plastics comprises a substrate which is plastic woven sack (2) and a metal layer which is formed that a plurality of strips parallel copper silks (4) laying on the surface of the plastic woven sack (2). The utility model has the advantages of low cost, light weight, convenient construction, difficult corrosion and fracture, durable using and good effect of warning.
Description
Technical field: the utility model relates to a kind of composite plastic woven warning mark band, relates in particular to a kind of composite plastic woven warning mark band that provided underground has gas pipeline that is used to warn.
Background technology: in modern city is built, often need various pipes is embedded in about underground more than 1 meter from the face of land, if there is not warning mark, when the needs trimming is excavated, be easy to run into pipeline, the light then economic loss that causes pipeline to damage, heavy then cause security incident, especially inflammable gas pipeline gas leakage will cause immeasurable loss to people's lives and properties.
Existing composite plastic woven warning mark band, the rubber article of most of employing 10～60cm is laid one deck lead foil and is made, composite plastic woven warning mark band is layed in the soil layer top that is embedded with pipeline, about 50cm place from the face of land, earlier survey its underground position of living in before excavating by instrumentation, avoid the position of composite plastic woven warning mark band during excavation, do not injure the pipeline under it, however its cost of products height, Heavy Weight, construction is inconvenient, and is embedded in underground, perishable for a long time, easily aging, be not durable, touch because of carelessness also during excavation and can rupture, composite plastic woven warning mark band is weakened or lose warning function.
Summary of the invention: the purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of cost is low, in light weight, easy construction, is difficult for burn into not easy fracture, long-lived composite plastic woven warning mark band.
In order to address the above problem, the utility model adopts following technical scheme: composite plastic woven warning mark band comprises matrix and metal level, described matrix is the plastic knitting band, and described metal level is some the copper wires of parallel lay-up on described plastic knitting belt surface substantially.
Also compound layer of polyethylene film on the described copper wire, described copper wire is 1～2, and diameter is φ 0.21mm, and described composite plastic woven warning mark band fabric width is 10～20cm.
Adopt technique scheme, the utility model has reduced cost, has alleviated weight, and composite plastic woven warning mark band has certain pliability, makes construction convenient, durable in use.Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the utility model A-A cut-open view;
Accompanying drawing 3 is the utility model embodiment partial enlarged drawing.
Embodiment: shown in accompanying drawing 1-3; the plastic tape braiding that plastic knitting band 2 adopts width to be about 2mm forms; the one side of plastic knitting band 2 is laid with one deck polypropylene film 1; another side by lay thermoplastic polypropylene film on it and two at interval about 9cm slightly be parallel to copper wire 4 compound stickings of plastic knitting band 2 longitudinallies; copper wire 4 diameters are φ 0.21mm; be provided with also heat on the plastic knitting band 2 of copper wire 4 roll extrusion compound layer of polyethylene protective film 5, the width of plastic knitting band 2 is made as 20cm.
Claims (7)
