Description

Pin for ditecting path of underground buried pipe embedded with magnet}

The present invention relates to a pipeline marker pin for indicating the buried position of underground pipes such as gas pipes, oil pipelines, communication lines, and water and sewage pipes, and more specifically, in the coupling portion of the head and fixing pins of the pipeline marker pins. The built-in magnetic body makes it easy to detect the position of the pipe marker pin even when the pipe marker pin is not exposed due to the resurfacing of roads or sidewalks or the breakage of the head. As part of the construction of survey geographic information system, it is used as a reference pin for the pipeline marker pin that can also be used as underground buried management system.

Pipe marker pins, also known as line marks, are embedded directly in the ground where underground buried pipes are located.

In other words, gas pipes, oil pipelines, communication lines, water, sewage pipes, and high-pressure pipelines are usually buried underground for the purpose of improving the urban environment, utilizing available space, and protecting various pipes. Since it may cause a large accident during work such as excavation or drilling, a separate pipeline marker pin is put on the ground surface where the underground burial pipe is located to prevent the safety accident by displaying the location, type and direction of the underground burial pipe. will be.

In particular, the pipeline marker pin is composed of a fixed pin that is directly inserted and fixed to the ground surface and the head coupled to the upper side of the fixing pin, because the head is directly exposed to the ground surface characteristics of the underground buried pipe on the surface of the head The efficiency can be further increased by simply displaying the type, embedding direction, etc. in letters or symbols.

However, the above-mentioned pipeline marker pins have a problem that the pipeline marker pins are crushed due to the repair work such as repaving or covering the road, resurfacing the sidewalk, and depositing various contaminants. If the pipe marker pin is crushed, the location and type of underground buried pipe cannot be identified, which will cause a large accident during excavation and drilling.

Therefore, although the pipeline marker pin is formed of a synthetic resin material and a magnet body is built into the inside, the pipeline marker pin has been proposed, but it is possible to detect the pipeline marker pin in a buried state by the magnet body. However, because the pipe marker pin on the synthetic resin material can not be directly driven into the road or sidewalk there is a hassle to install after drilling a separate insertion hole, the head portion is damaged by frequent friction with cars or pedestrians And it is broken, its service life is also a temporary problem is very unreasonable.

In particular, the synthetic resin pipe marking pins as described above, as described in the construction specifications required by the government, the material of the pipe marking pins KS D5101 (copper alloy rod), KS D5001 (brass casting) or the like or more In addition, since the pin part of the pipe marker pin is specified to use KS D3503 (rolled steel for general structure) or the same material or more, the synthetic resin pipe marker pin as described above cannot be adopted by itself and is cumbersome by the cumbersome installation process. It is a problem that practical application itself is impossible.

The present invention was conceived to eliminate the problems described above, the upper side of the metal head formed with a coupling portion having a display portion having the contents such as the type and direction of the underground buried pipe and the insertion hole in the lower side, and Consists of a metal fixing pin press-fitted into the lower coupler, by forging fixing the fixing pin to the head coupler in a state in which a separate magnet body is embedded in the coupler,

In the case of repaving and overlaying the road after installing the pipeline marker pin on the surface, the pipeline marker pin can be easily detected by a separate magnetic detector even if the pipeline marker pin is placed in the buried state. In addition, since it detects the magnet body by the magnetic detector, there is no detection confusion by the surrounding metals, so the purpose is to provide a pipeline marker pin for underground buried pipe detection that enables the clearer pipe detection. In addition, the purpose of the present invention is to use it as a basement buried management system by using it as a survey reference pin as part of the construction of a survey geographic information system (GIS).

Hereinafter, preferred embodiments of the present invention will be described.

1 is an exploded perspective view of a pipeline marker pin according to the present invention, Figure 2 is a side cross-sectional view of the pipeline marker pin according to the present invention.

A head pipe 4 having a display portion 1 formed on an upper surface thereof, a protrusion 3 having an insertion hole 2 formed on the lower side thereof, and a known pipe line in which a fixing pin 5 is inserted below the head 4. In the display pin,

The head 4 and the fixing pin 5 are formed of a metal working material, and the disc-shaped magnet body 10 is embedded in the insertion hole 2 of the protrusion 3,

Insert the tip of the fixing pin (5) into the insertion hole (2) of the projection (3) and forging and pressing the outer peripheral surface of the projection (3) so that the fixing pin (5) to the projection (3) of the head (4) It is fixed downward.

Referring to the action of the pipe marker for detecting underground buried pipes incorporating the subject innovation magnet according to the configuration as described above in more detail as follows.

The pipe marker pin of the present invention is formed on the upper surface of the head (4) as shown in the display section (1) for stamping or recording various information about the underground buried pipe, that is, the type and characteristics of the buried pipe, buried direction, etc. are formed And a projection 3 having an insertion hole 2 formed thereon.

The tip of the fixing pin 5 of the metal material is inserted into the insertion hole 2 of the lower protrusion 3 of the head 4.

At this time, the fixing hole 5 is inserted into the insertion hole 2 in the state in which the separate magnet body 10 is inserted, and the outer circumferential surface of the protruding portion 3 is forged and pressed to fix it from the protruding portion 3. The pin 5 is to be firmly fixed.

Therefore, after hitting and fixing the marker pin directly on the ground surface where the underground buried pipe is located as shown in FIG. 3, in the normal installation state, the type and buried direction of the underground buried pipe can be observed by visual confirmation.

When the head 4 of the marker pin is crushed during maintenance work such as repaving or overlaying roads or depositing various contaminants, a marker in a buried state can be detected by using a separate magnetic detector. As a result, it is possible to know the buried position and the buried direction of the underground buried pipe.

At this time, the magnetic detector used (Magnetic Detector) can be detected more precisely than the metal detector, it may also directly detect the metal pipe marker pin using a metal detector, there is a metal body in the proximity or metal material such as garbage in the ground Or, if there is other metal material, it is impossible to detect the correct pipe marker pin.

As described above, by using a magnetic detector that can directly detect only the magnet body 10, it is possible to check the position of the pipe marker pin more accurately.

Therefore, the pipe marker pin of the present invention is made of a metal head (4) and the fixing pin (5) can not only satisfy the mechanical strength required in the usual construction specifications, but also by the built-in magnet body 10 Even if the pipe marker pin is knocked out, accurate detection is possible, thereby preventing a safety accident.

The pipe marker pin for detecting the underground buried pipe with the magnet according to the present invention as described above is separately installed even when the pipe marker pin is placed in the buried state after the pipe marker is installed on the surface. It is possible to easily detect the pipeline marker pin by the magnetic detector of the magnetic detector, and to detect the magnet body by the magnetic detector, so that there is no detection chaos by the surrounding metal, so the pipeline detection can be more clearly detected. As part of the construction of GIS (Geographic Survey Information System), it is useful to be used as underground buried management system by using it as a survey reference pin.
