Abstract

The utility model relates to a grounding pipeline alarm band, particularly be used on a gas pipeline which is laid under the ground and is easy to explode and burn as an alarm mark, and the utility model can also be used in the laying of underground water pipes, underground wires and cable pipes. The utility model is composed of a band body with an alarm pattern mark and a protective layer, and the band body also comprises interval and continuous folding double layers which are fixed by connectors. When the utility model is used, the gas pipeline is laid under the ground, and the alarm band is laid in the ground having a distance of 30-60 centimeters to the just top of the pipeline. If a digging mechanism pulls the alarm band in a construction site, the sewing threads of both sides are broken and the folding double layers are scattered into a single-layer and is hung out of the earth, and thereby, the mark can be seen clearly, so construction workers stop operating, and thus the grounding pipeline alarm band play a role of protecting the grounding pipeline.

Description

The underground pipeline warning tape

The utility model relates to and a kind ofly is used to be laid on underground, particularly is laid on above underground, explosive, the inflammable gas piping underground pipeline warning tape as alert flag.

Originally in provided underground pipeline or other job execution, mainly by the manually-operated mining clay, it is met, and the possibility of other pipeline is less, destructiveness is also little.And now along with the raising of mechanization degree, for raising the efficiency, making up for lost time, a lot of working-yards all adopt excavator to cut the earth, if operation is careless, will run into other underground pipeline like this.Just very big because of being its destructiveness of mechanically actuated, lose also big.Especially it is just bigger to run in the gas piping this inflammable, explosive gas harmfulness.Existing warning tape is the individual layer strip, and excavator digs the two of having no progeny and still is embedded in underground cannot see, the caution weak effect.

The purpose of this utility model is to provide a kind of underground pipeline warning tape simple in structure, is laid on undergroundly, can warn the operator at the construction field (site) and be covered with pipeline, good warning effect below careful.

The utility model is achieved in that the underground pipeline warning tape is made of the belt body that has warning picture mark and protective seam, and also comprises spaced, continuous folded layer on the belt body, and fixes with web member.

Fig. 1, structural representation of the present utility model.

The vertical view of Fig. 2, Fig. 1.(no sewing line)

Fig. 3, alternative plan structural representation.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

Web member is sewing line (5) or cementing agent.

The long and narrow strip of belt body (1) for making by coloured fiberglass braided band, protective seam (4) is the PVC film, mark (3) was returned and is not seen after the time that prevents was long.To be printed on " have down gas pipeline, * * piped gas company and alarm call, explosive, danger " warning picture mark (3) be imprinted on the back side of PVC film, again protective seam (4) film is overlying on the belt body (1) with machine.By mark (3) whole piece belt body (1) is divided into a plurality of identical, equal in length, continuous unit (2).

With belt body (1) with unit (2) be standard equidistant, at interval, folding, as first module is individual layer, the second unit folk prescription is constituted folded layer (6) to doubling, folding and overlapping under the first half of Unit the 3rd, again the 4th unit doubling, folding are also overlapped under the first half of Unit the 5th, the folding direction is identical with Unit second, makes the warning tape of certain-length by that analogy.In a unit (2), half is an individual layer, and half is three layers a folded layer (6).Utilize use in sewing machine sewing line (5) fixing in the two edges of belt body (1), promptly no matter whether the place of folding, overlayer is arranged, all use sewing line (5) to make fixing continuously for ease of processing.

Also can adopt the scheme of two-way folding, be that first module is an individual layer, also overlap at 1/4 place at first module end and 1/4 place of three unit head end towards both sides doubling, folding Unit second, and Unit the 4th repeats the folding method of Unit second again, make the warning tape of certain-length by that analogy, both sides use stitching sewing machine line (5) fixing again.

During use, gas piping is laid on underground, and this warning tape be laid on underground directly over pipeline 30～60 centimeters places.If site operation excavator hook is moved this warning tape to, then the sewing line on both sides (5) is broken, and folded layer (6) is shattered into individual layer and is hung out outside the earth by excavator, just can see mark clearly and want constructor's shut-down operation promptly to play the effect of protection underground pipeline.

This warning tape also can be widely used in the laying of foggara, cable, wiring conduit.

The utility model compared with prior art because the former warning tape that uses is individual layer, is incited somebody to action when excavator is run into Its pull-up, break, but two ends still are embedded in underground cannot see, so alarming effect is poor. Existing this caution with Folded layer, if run into excavator with its hook, pull-up, sewing line is broken, folded layer is shattered into individual layer, grows Belt body part by excavator hang out soil outer just can know see alert flag, so it is simple in structure, cost Low, easy manufacturing, and good warning effect.

Claims

1, a kind of underground pipeline warning tape: constitute by the belt body (1) that has warning picture mark (3) and protective seam (4), it is characterized in that also comprising on the belt body (1) spaced, continuous folded layer (6) and fix with web member.

2, warning tape according to claim 1, it is characterized in that web member is sewing line (5) or cementing agent, utilize use in sewing machine sewing line (5) fixing in the two edges of belt body (1), no matter whether have the place of overlayer (6) all to use sewing line (5) to make fixing continuously.

3; warning tape according to claim 1; it is characterized in that the long and narrow strip that belt body (1) is made into for coloured fiberglass braided band; protective seam (4) is the PVC film; to be printed on " gas pipeline is arranged down; * * piped gas company and alarm call; explosive; danger " warning picture mark (3) be imprinted on the back side of PVC film; again protective seam (4) is overlying on the belt body (1) with machine with film; be divided into whole piece belt body (1) a plurality of identical by mark (3); equal in length; continuous unit (2); with unit (2) is that standard is equidistant; at interval; folding; first module (2) is an individual layer; with Unit second (2) folk prescription to doubling; folding and overlapping constitute folded layer (6) under the first half of Unit the 3rd; again with the 4th unit doubling; folding and overlapping constitute folded layer (6) under the first half of Unit the 5th; the folding direction is identical with Unit second; make the warning tape of certain-length by this method; in a unit (2); half is an individual layer, and half is three layers a folded layer.
