When embedding grounding device and grounding rod to which conductive electrolyte can be put in, press the grounding rod, compact the soil, or press-fit the outer side of grounding rod with conductive electrolyte reducing material to increase the adhesion coefficient with soil. It will be understood by those of ordinary skill in the art, and a grounding device is developed that is effectively improved by inserting a grounding device by drilling the ground and inserting a conductive electrolyte reducing agent into the perforated interior.

Hereinafter, the problems of the prior art of the problem to be solved in relation to the present invention with reference to the accompanying drawings.

1A is a chassis diagram of a conventional spinning needle-mounted grounding apparatus capable of adding an electrolyte.

As shown in Figure 1a, the conventional grounding device, a plurality of discharge holes 501 are perforated on the side, and the upper and lower ends are composed of a ground body 201 and a conical needle 205 that is covered with a cover have.

It is common knowledge in the technical field of the present invention that the plurality of discharge holes 501 are provided in the grounding body so as to fill the conductive body reducing agent in the grounding body 201 and to attach a needle-like member. It will make sense to those who have.

In addition, when the ground is punctured, a mounting hole 502 having a predetermined size is formed, and when the ground body 201 is inserted into the inside of the mounting hole, the gap is generated in the mounting hole 502 and filled with the electrolyte product 204. It is configured to make the grounding effect more effective.

Figure 1b is a cross-sectional view of the conventional cylindrical core grounding rod.

When installing the ground rod on the ground as shown in Figure 1b to dig a ground rod insertion hole 410 of the depth to bury the ground rod in the soil 400, and insert the ground rod as shown in Figure 1b, the first pie ( 110) If the hard copper wire 30 is applied to one side of the rod and there is no groundwater layer at the position where the ground rod is to be buried, as shown in FIG. 1B, the second sealing nut 330 and the first sealing nut. Coupling coefficient with the soil due to the coupling between the conductive electrolyte gradually filled from the second pipe 310 into the first pipe 110 by opening the 130 and the conductive electrolyte filled in the voids generated in the mounting hole. If the grounding reduced soil filled to reduce the specific resistance of the original soil, the high-voltage current, etc. flowing from the outside is discharged to the ground through the ground reduction soil (500) It is a conversation.

In addition, as shown in FIG. 1B, when passing through the groundwater layer 600 flowing position, the first sealing nut of the first pipe 110 located in the groundwater passage layer is sealed and the conductive electrolyte filled into the ground rod is lost to the groundwater layer. To prevent the grounding is reduced by the full amount of ground reduction soil 500 is improved by the electrolyte is maximized.

However, such ground rods, when excavating the ground rod insertion hole in the longitudinal or transverse direction for embedding in the ground, it is difficult to fill the conductive electrolyte to the outside of the ground rod in the groundwater layer or inevitable void portion. In order to solve such problems, when the ground rod is formed only in a position that is not in contact with the groundwater layer or the void portion, it is accompanied by the trouble of digging a large number of ground rod insertion holes 410, and closely adheres to the soil 40 according to the change of the season. The coefficient is changed so that the effect of improving conductivity is low.

In addition, in the case where the ground rod is inserted through the mounting hole 502 by drilling the ground, the ground rod insertion hole 410 has a conical needle 205 formed in the longitudinal direction of the outer end of the soil 40 and the ground body 201. It should be formed stably in close contact with the soil at the bottom to maximize the discharge effect to the ground. In addition, since the buried place of the ground rod is inevitably limited, the excavation depth of the ground rod insertion hole 410 must be deeply reduced so that the unit area and quantity can be reduced, and at least one ground body 210 is connected to the mounting hole. (502) The soil contacting the tip of the sharp needle while maintaining the original shape of the plurality of protruding conical needles 205 attached from the upper end to the lower end should be formed to be in close contact with the earth with good conductivity. Distributed radiation effect is maximized.

However, when embedding the ground rod as described above, when drilling the mounting hole 502 deeply vertically, excavation with boring equipment, etc., the soil or rock and water removed at this time is attached to the bottom of the shim rod of the boring equipment The air compressor is blown to the outside discharge place by the powerful air pressure, and maintains the circular shape as much as possible, but it is difficult to maintain the circular shape when it is left for a long time. The ground body 210 is formed by connecting at least one or more connected unit weight is increased, it is difficult to be seated to the bottom of the excavation hole without damaging the multiple conical needles 205 attached and At the same time, sharp needle deformation of the conical needle 205 may be foreseen, and in order to selectively improve the soil in contact with the tip of the needle, There is room for improvement, because of limitations.

The present invention has been made in order to solve the above problems, it is configured by firmly attaching the spinning needles on the outer side of the pure copper pipe with excellent conductivity, mixed with a carbon-based material and copper powder excellent in conductivity and dispersion spinning effect. do.

Changes in the point where the groundwater layer or the cave layer exist, the effect of the season, the cycle of secular change due to the corrosion of the parts exposed to the ground straight rod, and the grounding effect due to the burnout of the conductive electrolyte outside the ground straight rod is reduced. It can be overcome, and the stop molding portion 506 and the straight line 609 is compatible to the combination of the inner and outer parts of the ground rod from the upper to the lower end of the excavation hole and the soil lipids.

At this time, it is possible to increase the conductivity and mutual adhesion coefficient of the contacting part, and harden with high quality conductive carbon-based component and copper powder which is in contact with the tip of the sharp spinning needle, and maintain the effect of low resistance for a long time. The purpose is to provide.
