DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. The present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

1 to 4, the grounding bar 100 according to the embodiment of the present invention is a pipe body made of copper having a purity of 99% or more, and is connected to the upper portion 111 and the lower portion 112 A ground rod main body 110 having an upper end and a lower end connected to an upper cap 113 and a lower end cap 114 and a rainwater inlet 122 formed in an upper portion 111 of the ground rod body 110, A rainwater outlet 124 formed in the lower end cap 114 and a ground reducing agent 130 filled in the lower portion 112 of the ground rod body 110.

The ground bar connecting terminal block 140 may further include a ground wire connecting terminal block 140 coupled to both sides of the upper portion 111 of the ground rod main body 110 and used to connect the ground wire 1.

It is possible to provide a merit that the ground line 1 can be cut and connected to the ground line directly in the field when the ground line 1 is connected through the ground line connection terminal block 140, .

In other words, since the conventional grounding rods are inconvenient for transportation and moving, it is necessary to shorten the grounding line to 30cm ~ 50cm and then weld the grounding rods, cut the grounding line according to the length again in the field, The connection resistance can be reduced by reducing the number of connections.

In addition, since the ground line connection terminal block 140 is provided, parallel connection of the ground bar 100 can be easily and conveniently performed, and connection resistance can be reduced in parallel connection.

In other words, in designing a grounding work, a design in which two or more grounding rods are connected in parallel is performed. In this case, the connection resistance due to the parallel connection can be reduced and the field construction can be conveniently performed.

The ground rod main body 110 is a pipe body made of copper having a purity of 99% or more, more preferably a pure pipe having a purity of 99.9% or more.

Here, the use of a pure pipe for the ground rod main body 110 can increase the electric conductivity, and because the pipe body is applied, the cross-sectional area can be widened, a low ground resistance value can be secured, .

The upper cap 113 and the lower end cap 114 coupled to the upper and lower ends of the ground rod main body 110 are configured to seal the ground rod main body 110 formed of a pipe body to secure a low ground resistance value .

2, the ground rod main body 110 may be extended in a configuration in which a plurality of the lower portions 112 are connected and connected by using a connecting connection socket 101 of a straight connection type according to necessity in the field, will be.

3, the ground rod main body 110 is connected to the upper portion 111 in a bent structure by using an L (L) -shaped connection socket 101 according to necessity in the field So that the L-shaped ground bar 100 can be used.

The rainwater inlet 122 formed in the upper portion 111 of the ground rod body 110 and the rainwater outlet 124 formed in the lower end cap 114 inflow rainwater from the upper side of the landfill, So that it can be discharged to the outside.

The ground reducing agent 130 has a strong adsorption property and is excellent in water absorption ability so that the grounding rod 100 can maintain a low ground resistance value and is purified and discharged when rainwater or contaminant flows into the grounding rod body 110 It is preferable to use an activated carbon.

Here, the activated carbon may be char or activated carbon. It may be more preferable to use charcoal which can be called natural activated carbon to be harmless to the environment as an environmentally friendly reducing agent, but activated carbon which can be called artificial activated carbon can also be used something to do.

Herein, the activated carbon has a characteristic that carbon is the main component and has very strong adsorption property. Therefore, it can absorb moisture of several times larger than the magnetic volume, and therefore it can always maintain a low resistance when applied to a ground reducing agent of the ground bar 100 Can provide advantages.

Herein, the ground reducing agent 130 may fill the end surface of the ground rod main body 110 by filling the active carbon into the inside of the ground rod body 110, absorb moisture, and thus keep the ground resistance value low at all times. And functions to purify rainwater or various contaminants through the rainwater inlet 122, thereby purifying and discharging rainwater or various pollutants.

Accordingly, eco-friendly grounding can be realized.

It is more preferable that the ground reducing agent 130 is mixed with activated carbon, which is a natural material, in order to ensure a low ground resistance because of excellent viscosity and no bubbles.

The ground reducing agent 130 may be prepared by mixing activated carbon and natural loess with water and mixing the active carbon and the natural loess with water to prepare a gel. The weight ratio of activated carbon: natural loess: water = 1: 3: 1 to 2: Or the volume ratio thereof.

In other words, since the ground reducing agent 130 having the above-described structure uses natural materials harmless to the environment, it is possible to maintain eco-friendly grounding while maintaining low ground resistance along with moisture absorption in the ground, It can be advantageous to purify the water and then discharge it back to the ground.

A construction method of the ground bar 100 according to the present invention having the above-described structure will be described with reference to FIG.

First, a grounding rod made of a copper pipe filled with a ground reducing agent is filled (S10).

At this time, it is assumed that the grounding rod has the grounding bar 100 having the structure described above with reference to Figs. 1 to 4.

That is, the grounding rod is a pipe body made of copper having a purity of 99% or more and is connected to the upper portion 111 and the lower portion 112 by the connection socket 101 and the upper end and the lower end are connected to the upper end cap 113 and the lower end cap A rainwater inlet 122 formed in an upper portion 111 of the ground rod main body 110 and a rainwater outlet 124 formed in the lower end cap 114, A ground reducing agent 130 filled in a lower portion 112 of the ground rod body 110 and a ground reducing agent 130 protruding from both sides of the upper portion 111 of the ground rod body 110 and used for connecting the ground wire 1 And a ground line connection terminal block 140. [

In addition, the ground reducing agent 130 uses activated carbon, and occasionally, loess of natural material may be mixed with activated carbon.

Here, the grounding bar is similar to the grounding bar 100 described above with reference to Figs. 1 to 4, and a detailed description thereof will be omitted.

A ground buried hole is formed so that the ground bar can be buried (S20).

After putting a ground rod filled with the ground reducing agent having the above-described configuration into the land filling hole, the reducing agent is injected into the land filling hole (S30).

In this case, the reducing agent may be a gel prepared by mixing activated carbon and natural loess into water, and filled in a space of a buried hole for filling the ground bar.

Next, the ground bar is inserted and a ground bar is buried in the ground by filling the space of the buried hole filled with the reducing agent (S40).

The above step S40 may be carried out in accordance with the buried environment for constructing the ground rods and the construction method, and the grounding of the ground rods may be completed through the step S30.

For example, when the boring grounding method is used, it is a method for obtaining a grounding resistance required for a marathon or a rocky area having a small earth resistance or a high earth resistance, using boring equipment And the grounding rod is buried by vertical boring (boring) operation.

At this time, the diameter of the boring hole (hole) is drilled to 120 mm to 160 mm, and the grounding rod is buried vertically with the standard of 50 mm, and an empty space formed between the perforated hole and the buried ground rod, And filled with a reducing agent prepared in the form of a gel to fill the ground rod with no void space.

In addition, when the construction using the L-type grounding method is carried out, this is a method of using the L-type grounding rod, which is used in a mountainous region where entry of the boring equipment is difficult and entry of the vehicle is impossible.

At this time, it is necessary to horizontally place the L-type ground bar horizontally and horizontally rather than perpendicularly with a maneuvering tester or a forkläne, then mix the active carbon and the natural loess with water to fill the gel, And then the ground rod is buried by covering the space with the soil.

Accordingly, in the present invention, eco-friendly grounding can be conveniently performed, a low ground resistance value can be secured and maintained while increasing the electric conductivity, and an eco-friendly ground reducing agent is used. Therefore, when rainwater and various pollutants are introduced, It can provide an advantage that it can be discharged to the ground.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of illustration, It will be apparent that various modifications and changes may be made by those skilled in the art.
