본 발명은 전주를 세워 매립설치하는 건주 공사시에 전주의 견고한 근착을 위해 전주의 하단부에 오거크레인용 확장기를 이용하여 매립되는 접지기능 전주근가의 접지저감제로 사용되는 도전성 콘크리트 조성물에 관한 것으로, 더욱 상세하게는 콘크리트 양생된 전주근가의 하부에서 금속재로된 접지판을 결합시키는 도전성 콘크리트로써, 전주근가에 적용시 견고한 결합력은 물론 하부 접지판의 접지효과를 향상시킴과 동시에 우수한 전기저항률과, 내구성의 향상과, 높은 압축강도를 얻을 수 있게 한 접지극 부착 전주근가용 도전성 콘크리트 조성물 및 그 제조방법에 관한 것이다.
The present invention relates to a conductive concrete composition used as a grounding reducer near the grounding function of electric poles, which are buried using an auger crane expander at the lower end of the poles for the strong mounting of the poles in the construction of the construction of the poles. In detail, it is a conductive concrete that combines a ground plate made of metal at the bottom of the concrete-cured electric pole, which improves the grounding effect of the lower ground plate as well as solid bonding force when applied to the electric pole, and has excellent electrical resistivity and durability. The present invention relates to an electroconductive concrete composition for pole pole attachment with a grounding electrode and to a method of manufacturing the same, which has improved and obtained high compressive strength.

현행 가공 배전공사 시 가공지선과 완철 또는 피뢰기나 변압기 등과 같은 전주상에 설치되는 기기류 및 중성선의 대지 접지를 위한 접지공사를 시행함에 있어 접지동봉이나 심타봉 및 접지저항 저감제를 사용한 접지 시공법이 널리 적용되고 있다.Grounding method using grounding rod, core rod, and grounding resistance reducing agent is widely used in grounding work for earth grounding of equipments and neutral wires installed on poles such as processed ground wire and finished iron or lightning arrester or transformer. Is being applied.

현행 접지 시공법에 대해서 간략히 살펴보면, 접지동봉을 사용하는 접지 시공의 경우 접지동봉을 해머로 타격하여 매설한 후 전주 내부를 통하여 지표면 이하 1m 지점에 있는 전주의 접지선 인출구로부터 인출된 접지선과 접지동봉의 상부에 접지극 리드선을 연결하는 형태로 이루어지며, 이때 접지극 리드선은 지표면 이하 0.75m 이상 매설되도록 시공되고 있다.The current ground construction method is briefly described in the case of grounding construction using grounding rods. After burying the grounding rods with a hammer and burying them, the grounding wires drawn out from the grounding wire outlets located 1m below the ground surface through the inside of the poles and the upper side of the grounding rods. The ground electrode lead wire is connected to the ground electrode lead, and the ground electrode lead wire is constructed to be buried at least 0.75m below the ground surface.

또한, 접지선과 접지극 리드선과의 접속은 스리브 등에 의한 압축접속 또는 권부접속등의 방법으로 접속하며, 접지장소의 토질 또는 현장여건으로 인하여 규정된 접지저항치를 얻기 어려운 곳에서는 다극접지공법 또는 심타 접지공법 등을 적용하거나, 접지개소 주변의 환경오염 우려가 없는 고강도 접지저항 저감제 등을 사용하여 시공하고 있는 것이 현실이다.In addition, the connection between the ground wire and the ground electrode lead wire may be made by compression or winding connection by a sleeve, etc., and the multipole grounding method or the core grounding method should be used where it is difficult to obtain the prescribed ground resistance due to the soil or site conditions of the grounding site. It is a reality to use a high strength earth resistance reducing agent or the like that does not have the concern of environmental pollution around the grounding point.

이러한 접지공사는, 건주공사 완료 후 접지동봉을 매설하기 위해서는 추가로 굴착작업을 하여야 하고, 타격식 접지동봉을 매설하기 위해 인력 수공작업에 의존하여야 하며, 접지공사 시 원하는 접지저항치를 얻기가 쉽지않으며, 경년변화에 따른 접지성능 저하로 정기적인 유지보수작업이 수반되는 문제점이 있는 것이다.Such grounding work requires additional excavation work to bury the grounding rod after completion of the construction work, and relies on manual labor to bury the striking grounding rod. However, there is a problem that regular maintenance work is accompanied by deterioration of grounding performance due to secular variation.

이에 따라 본 발명 출원인은 2006년 특허출원 제113665호와 같이, 아치형 전주근가에 대하여 현행 접지공사에 사용되는 접지동봉이나 심타봉을 대체하는 접지판을 일체로 형성한 접지기능이 있는 아치형 전주근가를 이용하여, 접지공사를 위한 별도의 추가 굴착공정 없이 전주근가 장착공정과 동시에 접지공사가 효과적으로 이루어져 획기적으로 공정을 줄일 수 있는, 전주근가 장착 공정 시 접지공사를 병행할 수 있는 접지판(Earth Plate) 일체식 전주근가를 제안한 바 있다.Accordingly, the applicant of the present invention, as in 2006 Patent Application No. 113665, the arch-shaped pole pole with a grounding function integrally formed with a ground plate to replace the ground rod or core rod used in the current grounding construction Earth plate that can be grounded at the time of mounting the root pole, which can reduce the process dramatically because the grounding work is done effectively at the same time without the additional excavation process for grounding. We have proposed an integrated Jeonju Root Price.

그러나, 상기한 바와 같은 접지판을 갖는 전주근가의 경우 그 접지판에 대한 구체적인 구성이나 작용의 구체적인 언급이 없어서, 개량된 아치형 전주근가에 상기한 접지판을 적용하기 위해서는 그 전주근가의 형상과 일치하는 평면 형상을 갖추어야 하면서도, 그 접지판으로부터 인출된 리드선을 전주로부터 발생하는 접지선과 용이하게 연결할 수 있도록 하는 기술적 구성이 부여되어야 하는 것이다However, in the case of the electric pole having a ground plate as described above, there is no specific configuration or operation of the ground plate, and in order to apply the ground plate to the improved arc-shaped pole pole, the shape of the pole pole is consistent with the shape of the pole pole. It should have a planar shape, but a technical configuration should be given so that the lead wire drawn out from the ground plate can be easily connected with the ground wire generated from the pole.

또한, 상기한 바와 같은 전주근가 및 그 접지판은 콘크리트로 이루어진 전주근가와 금속재로 된 접지판의 상호 결합력은 우수하나 금속재의 접지판이 토양의 성분에 따라 전식 등의 화학변화를 일으켜 표면 부식이 진행되어 기존의 접지시스템과 같이 동일하게 접지판의 기능이 약화되는 문제점을 갖고 있는 것이다.In addition, the electric pole and the ground plate as described above is excellent in the mutual bonding strength of the electric pole of the concrete and the ground plate made of metal, but the ground plate of the metal material causes chemical changes such as corrosion according to the composition of the soil surface corrosion progresses The problem is that the ground plate is weakened in the same way as the conventional grounding system.

또한, 금속재로 된 접지판은 기존 접지동봉 등의 시공방법과 같은 매설 상태이므로 고온 다습한 토양 내부 환경에 의해 쉽게 부식되므로 그 사용수명이 짧고 접지 효과가 약화되는 등의 문제점을 내포하고 있는 것이다.In addition, since the ground plate made of metal is buried under the same construction method as the existing grounding rod, it is easily corroded by the environment of high temperature and high humidity, so that the service life is short and the grounding effect is weakened.

이에 따라 본 발명 출원인은 2007년 특허출원 제0108102호와 같이, 평면상 아치형 전주근가의 형상을 갖추면서도, 콘크리트 양생된 전주근가와 금속재로 된 접지판의 사이에 접지저감제로 사용되는 도전성 콘크리트층을 형성함으로써, 접지근가와 접지판의 결합력 향상은 물론 우수한 접지효과를 얻으면서도 경년변화가 거의 없고 전식 및 부식 방지 효과가 탁월하므로, 종래의 전주근가가 갖는 제반의 문제점을 극복할 수 있는 도전성 콘크리트층을 갖는 접지기능 아치형 전주근가를 제안한바 있다.Accordingly, the applicant of the present invention has a conductive concrete layer which is used as a ground reducing agent between the concrete cured pole and the ground plate made of metal, while having the shape of a flat arch-shaped pole pole, as in 2007 Patent Application No. 0108102. The conductive concrete layer that can overcome the problems of the conventional electric pole price because it is formed, there is not only a secular change and excellent anti-aging effect and corrosion prevention effect, but also improve the bonding strength of the ground root and the ground plate, and excellent grounding effect We have proposed a grounding function arch type pole root with

그러나 상기와 같은 전주근가의 도전성 콘크리트층은, 단순 시멘트를 주성분으로 조성되어 있는 것인바, 전주근가에 적용시 그 도전성 콘크리트의 효과를 얻기에 미흡하며, 특히, 결합력의 저하와 낮은 전기저항률, 내구성 저하와, 압축강도의 저하를 가져오는 문제점을 내포하고 있었다.
However, the conductive concrete layer of the main pole value as described above is composed of simple cement as the main component, when applied to the main pole value is insufficient to obtain the effect of the conductive concrete, in particular, the decrease in the bonding strength and low electrical resistivity, durability There was a problem of lowering and lowering of compressive strength.

본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 도전성 콘크리트를 형상 유지 및 결합재 역할을 하는 포틀랜드 시멘트와, 재료의 강도 및 내구성을 향상시켜주는 골재 및 모래와, 전기 전도성을 부여와 높은 압축강도를 얻기 위한 도전성재료인 탄소섬유와, 유동성 확보를 위한 물을 혼합하여 조성된 도전성 콘크리트를 전주근가에 적용함으로써, 전주근가용 도전성 콘크리트의 접지저감제로서 전주근가와 접지판과의 견고한 결합력을 부여함과 동시에 우수한 전기저항률을 가지게 하고, 특히, 내구성 및 압축강도를 향상시키며, 땅속에서는 부식이 되지 않고 물에 녹지 않아 반영구적으로 사용할 수 있게 하는 접지극 부착 전주근가용 도전성 콘크리트 조성물 및 그 제조방법을 제공함에 본 발명의 목적이 있는 것이다.
