Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a marker that allows the location of underground pipes such as gas pipes, water pipes, and electrical wiring to be recognized from above ground.

[Problems to be solved by the prior art and the invention]

On newly constructed residential and factory sites, gas pipes, water pipes, electrical wiring, etc. are usually buried underground to the planned locations before the building is completed. . However, most of them are still under construction, so it is necessary to indicate their location. For this reason, conventionally wooden or resin stakes were driven into the buried location, with the upper part of the stake exposed about 5 to 15 cm above the ground. However, such piles are only driven into the ends, and are often knocked over, broken, or even lost by other work vehicles, making it difficult to reliably mark the location of underground pipes. was difficult. The present invention aims to provide a marker that will not be damaged or lost even when a work vehicle passes by or otherwise.

[Means for solving problems]

This invention is intended to solve the above problems.
This is a vertically long underground pipe indicator made entirely of elastic flexible rubber or synthetic resin. At the bottom of the part to be embedded,
This is a marker for underground pipes that is provided with one or more vertical cuts into which underground pipes can be inserted.

The sign according to the present invention has a display part, that is, a surface-exposed part, on the top of which displays information such as gas, water, electricity, etc., in a way that does not easily disappear, depending on the type of underground pipe. This display portion should be approximately 5 to 15 cm from the top end and should be exposed to the ground. This display section may be displayed in different colors as required by law, such as green for gas pipes,
It is a good idea to color water pipes blue, electrical wiring yellow, and petroleum wiring red. In addition, for underground pipes, it is sufficient to open the cut in the indicator and insert the pipe before burying the pipe.

[Effect]

Since the indicator according to the present invention is connected to underground pipes and is flexible, it will not be damaged or lost due to work vehicles passing over the indicator above the ground, and it will not be lost. Also, since it is made of synthetic resin, it can be used semi-permanently without corroding even if it is buried underground. In addition, in normal cases, the ends of the buried pipes that are installed in advance are closed, and they are connected to the piping of the building after the building is completed. If there is no need to leave the marker permanently when making this connection, it is easy to remove the marker when making the connection, and since the removed marker is not damaged in any way, it is easy to reuse it. be.

On the other hand, the depth of the buried pipe is not always constant, so in some cases, multiple cuts are made as shown in Figure 3, and the buried pipe is inserted into any cut depending on the depth. In this way, only the display section may be exposed above the ground. Furthermore, even if there is only one cut, if the buried position is shallow, a marker may be attached as shown in FIG. Although not shown in the diagram, if it is difficult to pass the pipe through the cut, pass the lower part of the indicator under the pipe and pull it up, open the cut and pass the indicator through the upper part (display part) of the indicator and loop the indicator itself. The top can be pulled up and connected to markers and piping. Furthermore, if the marker according to the present invention is pulled for some reason, underground piping connected to it may be affected. In order to prevent this kind of danger, it is preferable to provide a claw in the upper half to prevent it from coming off as shown in Figure 2, and a through hole in the center as shown in Figure 3. It is also preferable to insert and bury an auxiliary tool for preventing slippage into the hole.

〔Example〕

FIG. 1 is an explanatory diagram showing a buried state of an underground pipe using a marker according to the present invention. 1 is the main body of the sign, which is a flexible rubber plate with a length of about 500 to 800 mm, a width of 30 to 70 mm, and a thickness of 5 to 30 mm. 2 is about the length
The cut is 100 to 300 mm, and 3 is a small hole provided at both ends of the cut to prevent the cut from tearing. Reference numeral 4 indicates the ground surface, and 5 indicates a display section exposed above the ground, that is, an exposed section of the ground surface, which in this embodiment is indicated as gas and is marked with an arrow. 6 is a pipe, 7 is a joint, and 8 is a blind plate at the end of the pipe.

FIG. 2 is a front view of only the marker, and 9 is a claw for preventing it from coming off, which is provided as necessary.

FIG. 3 is a front view of another embodiment of the marker, in which two cuts are provided, and 10 is a through hole provided as necessary, and as shown in FIG.
A slip-off prevention aid 11 is inserted into the marker to prevent it from slipping off when the upper part of the marker is pulled.

FIG. 4 is an explanatory diagram showing another embodiment of the buried state of the piping, and 10 and 11 are through holes and slip-off prevention aids provided as necessary, respectively.

In the drawings, only the case where the main body 1 is a liquid body is illustrated, but the same effect can be obtained even if the body 1 is a rod-shaped body or a column-shaped body.

[Effect of idea]

Since the marker according to the present invention is directly connected to the underground pipe, unlike conventional piles, it will not be removed or lost, and will continue to function as a marker forever. Furthermore, the parts exposed above the ground are naturally flexible, so even if a work vehicle passes over them, they will not break or break due to their elasticity, and after passing over them, they will be restored to their original state due to their elasticity. It returns to its normal state and always acts as a beacon to prevent unexpected accidents. Furthermore, it is flexible, easy to install, and can be used in a variety of ways. Furthermore, when it is no longer needed, it can be easily removed and reused.

[Brief explanation of drawings]

FIGS. 1 and 4 are explanatory diagrams of a case in which pipes are buried underground using the marker according to the present invention, and FIGS. 2 and 3 are front views of the marker itself. 1 is the main body of the sign, 2 is the cut, 3 is the small hole for preventing tearing, 4 is the ground surface, 5 is the exposed part of the ground surface, and 6 is the piping.
