Description

{Apparatus for Protecting Underground Facilities}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underground buried object protecting apparatus, and more particularly, to an underground buried object protecting apparatus capable of informing that an underground buried object exists.

Underground burials refer to water and gas pipelines such as water and sewage pipes, gas gas pipes, electric power cables, telephone lines, gas pipes, optical cables, sewer gas pipes, and sewage gas pipes.

Since such underground burials are buried and cover the ground, it is not possible to determine where buried underground burials have buried over time. Therefore, digging up the ground later frequently destroys or destroys the underground.

Furthermore, if the underground material is damaged or destroyed, it will not be possible to use tap water, electricity, telephone, or network, etc., supplied through the underground underground until it is restored, It is also dangerous that some of them are exploded in the underground.

Conventionally, in order to notify the burial of underground objects, a signboard has been used. However, in this method, there is a problem that the location of the buried object can not be guided when the signboard is lost.

Conventionally, a technique has been developed in which a protective member incorporating a colored gas is provided at the top of a subterranean buried object, and a location of the underground object is informed by the colored gas when the protective member is broken.

Such colored gas is not present by the present technology, and even if it exists, it can spread to the atmosphere immediately upon spill, so that the position of the underground material can not be continuously notified.

In addition, the conventional apparatus for protecting underground objects using colored gas is hermetically sealed by a nut member and is vulnerable to gas tightness.

At this time, it is preferable that a plurality of gas pipes 20 are provided so as to better bear the load as the load from the ground is dispersed. Herein, the case where a plurality of gas pipes 20 are provided will be described as an example.

Here, each gas pipe 20 may be made of a material having high-density polyethylene or higher performance.

At this time, the gas may be an environmentally friendly nitrogen gas which is abundant in the human body and may be an ammonia gas. The gas may have a pressure of ² kg / cm ² . When ammonia gas is used as the gas, the location of the underground burial can be informed by the smell of the gas, as well as the color of the powdered powder.

The powdered powder is composed of a material which is not combined with water, and may be a color different from the earth color of the landfill in which the underground burial protection apparatus according to the embodiment of the present invention is embedded, for example, a fluorescent red powder.

Here, the powdered powder may be made of a material that does not aggregate by moisture. Accordingly, in the present invention, even if water is generated in the gas pipe 20, it is possible to prevent the powder from being accumulated by the water.

For example, the powdered powder may include at least a part of a hygroscopic material such as zeolite bentonite, montmorillonite and the like.

These powdered powders can be manufactured to have a corresponding color using an edible color harmless to the human body.

Each gas pipe 20 includes a body 250, an inner cap 220, and an outer cap 230. The tubular body 250, the inner cap 220, and the outer cap 230 may be made of a material having high-density polyethylene or higher performance. Hereinafter, each component of the gas pipe 20 will be described.

The tubular body 250 has a space filled with the powdered powder and gas therein. One end of the tubular body 250 is formed in an airtight form from the time of manufacture, and the other end thereof has an open gas inlet 210 at the time of manufacture.
