여기서 상부 끝에 중공형 하우징(26)이 일체로 된 일정 길이의 PVC 재질의 중공관(18)을 구비한다.Here the hollow housing 26 is provided with a hollow tube 18 of PVC material of a predetermined length in which the hollow housing 26 is integrated.

한편 상기 중공형 하우징(26)의 둘레면에는 다수의 통풍구(28)가 형성되고 개방된 상부면에는 덮개(30)가 부착된다.Meanwhile, a plurality of vent holes 28 are formed on the circumferential surface of the hollow housing 26, and a cover 30 is attached to the open upper surface.

따라서 상기와 같이 구비된 중공관(18) 하단끝과 상기 접지봉(10a)의 중공부(20) 입구가 연결되도록 하는 바, 스테인레스 재질의 연결관(14)을 사용하여 연결 고정시킨다.Therefore, the bottom end of the hollow tube 18 provided as described above and the inlet of the hollow portion 20 of the ground rod 10a are connected to each other, and the connection pipe 14 is made of stainless steel.

이때 상기 연결관(14)의 하단은 상기 접지봉(10a)의 중공부(20) 입구에 일체가 되어 성형되고, 상부 개방부에 상기 중공관(18)의 하단끝이 삽입 고정된다.At this time, the lower end of the connecting pipe 14 is integrally formed at the inlet of the hollow portion 20 of the ground rod 10a, and the lower end of the hollow tube 18 is inserted and fixed to the upper opening portion.

이에 따라 상기 하우징(26)을 포함하는 중공관(18)을 외부로 노출되도록 즉, 연결관(14) 위쪽이 외부로 노출되도록 하여 상기 접지봉(10a)을 일정 깊이의 토양(16)속에 매설한다.Accordingly, the ground rod 10a is embedded in the soil 16 of a predetermined depth so that the hollow tube 18 including the housing 26 is exposed to the outside, that is, the upper portion of the connecting pipe 14 is exposed to the outside. .

상기와 같이 설치된 상태의 접지봉(10a)의 사용 상태를 첨부한 도 2를 참조하여 설명하면 다음과 같다.Referring to Figure 2 attached to the use state of the ground rod (10a) of the installed state as described above are as follows.

이어서 상기 화학 저감제(22)는 중공관(18)과 연결관(14)을 경유하여 접지봉(10a)의 중공부(20)를 타고 밑으로 흐르게 된다.Subsequently, the chemical reducing agent 22 flows down through the hollow portion 20 of the ground rod 10a via the hollow tube 18 and the connection pipe 14.

따라서 상기 화학 저감제(22)는 접지봉(10a)의 중공부(20)의 하부 유출구(24)를 통하여 토양으로 흡수되어 진다.Therefore, the chemical reducing agent 22 is absorbed into the soil through the lower outlet 24 of the hollow portion 20 of the ground rod 10a.

상기 토양으로 흡수된 화학 저감제(22)는 상기 접지봉(10a)의 외부면으로 퍼져 도포되고 동시에 그 주변에 까지 퍼지게 된다.The chemical reducing agent 22 absorbed into the soil is spread and applied to the outer surface of the ground rod 10a and at the same time spread to the periphery thereof.

이때 상기 접지봉(10a)의 외부면과 그 주변에 퍼진 화학 저감제(22)는 접지봉(10a)의 외부면과 토양과의 밀착력을 증대시켜주는 동시에 접지봉(10a)의 접지 저항 저감 능력을 향상시키게 된다.At this time, the chemical reducing agent 22 spread around the outer surface of the ground rod 10a increases the adhesion between the outer surface of the ground rod 10a and the soil and at the same time improves the grounding resistance of the ground rod 10a. do.

상기 화학 저감제(22)가 일정 기간이 지나서 제기능을 발휘할 수 없을때에는 다시 중공관(18)의 하우징(26)을 통하여 화학 저감제(22)를 재투입하여 항상 일정한 접지 저항값을 갖도록 조절 할 수 있다.When the chemical reducing agent 22 cannot function properly after a certain period of time, the chemical reducing agent 22 is re-introduced through the housing 26 of the hollow tube 18 and adjusted to always have a constant ground resistance value. can do.

또한 상기 접지봉(10a)은 상기 하우징(26)에 형성된 통풍구(28)를 통하여 외부의 건조 공기가 토양속에 매설된 접지봉(10a)의 중공부(20)까지 흘러 들어가게 되어 외부와 내부의 온도 차이 의해 습기가 생성되므로 접지봉(10a)은 항상 일정한 습도를 유지하게 된다.In addition, the ground rod 10a flows through the ventilation holes 28 formed in the housing 26 to the hollow portion 20 of the ground rod 10a embedded in the soil, thereby allowing the external dry air to flow into the ground rod 10a. Since moisture is generated, the ground rod 10a always maintains a constant humidity.

이상 상술한 바와 같이 본 발명에 따른 접지봉 설치 구조에 의하면 토양속의 접지봉에 화학 저감제를 용이하게 반복 투입할 수 있도록 하여 토양과의 접촉 저항을 저감시키는 동시에 토양과 접지봉의 밀착력이 높아져 접지 저항 저감력이 증대되는 잇점이 있고, 하우징의 통풍구를 통하여 외부 건조 공기가 흘러 들어가 토양속의 접지봉에 대한 습도가 자연적으로 조절되어 항상 일정한 접지 저항값을 유지할 수 있다.As described above, according to the structure of the ground rod installation according to the present invention, it is possible to easily and repeatedly add the chemical reducing agent to the ground rod in the soil, thereby reducing the contact resistance with the soil and increasing the adhesion between the soil and the ground rod, thereby reducing the ground resistance. There is an advantage of this increase, the external dry air flows through the vents of the housing, the humidity to the ground rod in the soil is naturally adjusted to always maintain a constant ground resistance value.
