Abstract

The present invention relates to an underbracing for an arch-shaped utility pole used to firmly erect a utility pole. The underbracing for an arch-shaped utility pole of the present invention is molded with just conductive concrete and general concrete since the conductive concrete layer disposed at the lower part of the underbracing for an arch-shaped utility pole is mixed with metal fragments during molding. The conductive concrete layer is connected to the reinforcing steel in the utility pole underbracing, and an additional lead wire is connected to the reinforcing steel. Therefore, the automation facility for an existing underbracing for an arch-shaped utility pole may be applied without changes so that the utility pole underbracing of the present invention can be suitable for mass production, and the error rate of the utility pole underbracing of the present invention may be close to zero so that the utility pole underbracing can be highly economical. The metal fragments in the conductive concrete layer further increase the grounding efficiency fn the conductive concrete layer by having the effect of reducing high grounding resistance, and the grounding efficiency can increase while production costs can be reduced even without using an expensive ground plate because the lead wire is welded directly with the thick reinforcing steel.

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 for grounding work for grounding of equipments and neutral wires installed on poles such as processed ground wires and finished wires or lightning arresters or transformers.

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. If you look at the current grounding method briefly, in the case of grounding construction using grounding rod, the grounding rod is hit with a hammer and buried, and the grounding wire drawn out from the grounding wire outlet of 1m below ground level through the inside of the pole. 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 심타접지공법 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 is connected by compression or winding connection by a sleeve, etc., and the multipole grounding method or deep earthing method should be used where it is difficult to obtain the prescribed ground resistance due to the soil or site conditions of the ground. 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 쉽지 않으며, 경년변화에 따른 접지성능 저하로 정기적인 유지보수작업이 수반되는 문제점이 있는 것이다.Such grounding work requires additional excavation work in order to bury the grounding rod after completion of the construction work, and rely on manual labor for laying the impacting 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.
또한, 2007년 특허출원 제69478호와 같이 상기한 전주근가의 문제점을 개선한 아치형 전주근가를 제안하되, 전주근가의 양단 상측에는 양끝올림부를 각각 형성하고, 그 전주근가의 아치형 후측부는 보다 작은 외경을 갖도록 축소 형성하며, 아치형 전주근가의 중앙부를 관통하는 후크삽입공과 그 양측에 슬릿 형태의 볼트결합공을 이격 형성함으로써, 양끝올림부를 통해 토양과의 접지력을 향상시키면서도 보다 축소된 후측부를 통해 전주근가의 경량화를 꾀하는 것이며, 후크삽입공은 크레인을 이용한 전주근가의 이동 및 투입 작업의 용이함을 제공하고, 볼트결합공은 U볼트의 체결을 용이하도록 한 양끝 올림부를 갖는 건주공사용 아치형 전주근가를 안출한 바 있는 것이다.In addition, as proposed in 2007 Patent Application No. 69478, the arch-shaped pre-tennis price is proposed to improve the above-mentioned problems of the perimeter, the upper end of each of the both ends of the rounded portion formed, respectively, the arcuate rear side of the pretend root It is reduced in size to have an outer diameter, and a hook insertion hole penetrating the center portion of the arcuate pole root and a slit-shaped bolt coupling hole are formed on both sides thereof, thereby improving the holding force with the soil through both end portions, and further reducing the rear side portion. It is intended to reduce the weight of the electric pole, the hook insertion hole provides the ease of movement and input work of the electric pole root using a crane, and the bolt coupling hole is an arch-shaped electric pole root for the dry worker having both ends raised to facilitate the fastening of the U bolt Will have devised.
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 것이다.However, 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 be provided with a planar shape, but the technical configuration to be able to easily connect the lead wire drawn out from the ground plate with the ground wire generated from the pole.
이에 따라 본 발명 출원인은 2007년 특허출원 제07189호와 같이, 평면상 아치형 전주근가의 형상을 갖추면서도, 그 아치형 접지판으로부터 용융접합방식으로 인출되는 리드선을 구성하되, 이들 접지판은 평판형 또는 그레이팅형, 와플형과 같이 다양하게 변경 적용하여 토양과의 접지력을 향상시키면서도, 전주의 접지선과 용이하게 연결 사용할 수 있게 하여, 콘크리트 타설에 의한 전주근가의 양생 제작시 그 접지판을 함께 결합시공함에 따라 우수한 생산성은 물론 전주근가의 설치 과정과 동시에 접지공사가 완료되므로 작업 효율성이 뛰어난 것이며, 토양과의 접촉 면적 및 접지 면적이 크게 향상되어 더욱 손쉽게 원하는 접지 저항값을 얻을 수 있어 접지 시공 작업의 편리성 및 효과가 극대화된 아치형 전주근가용 접지판을 제안한 바 있는 것이다.Accordingly, the applicant of the present invention, as in 2007 Patent Application No. 07189, forms a lead wire drawn out from the arced ground plate in a melt-bonding manner while having a shape of a flat arcuate pole, and the ground plates are flat or Various changes such as grating type and waffle type can be used to improve grounding power with soil, and can be easily connected with ground wire of Jeonju. As a result, the grounding work is completed as well as the excellent productivity as well as the installation of the electric pole near the ground, and the work efficiency is excellent. The contact area with the soil and the ground area are greatly improved, so that the desired ground resistance value can be obtained more easily. It has proposed an arched electric pole ground plate that maximizes the performance and effect.
그러나, 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.However, 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 of the metal material, but the ground plate of the metal material causes chemical changes such as erosion according to the soil composition, the 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 발명의 출원인은 특허등록 제0820070호와 같이 콘크리트 양생된 전주근가와 금속재로 된 접지판의 사이에 접지저감제로 사용되는 도전성 콘크리트층을 형성함으로써, 접지근가와 접지판의 결합력 향상은 물론 우수한 접지효과를 얻으면서도 경년 변화가 거의 없고 전식 및 부식 방지 효과가 탁월하므로, 종래의 전주근가가 갖는 제반의 문제점을 극복할 수 있는 도전성 콘크리트층을 갖는 접지기능 아치형 전주근가를 제안한 바 있는 것이다.Accordingly, the applicant of the present invention by forming a conductive concrete layer to be used as a ground reducing agent between the circumferential root cured concrete and the ground plate made of metal as shown in Patent Registration No. 0820070, improving the bonding strength of the ground root and ground plate Of course, because it has excellent grounding effect, almost no secular change, and excellent effect of preventing corrosion and corrosion, it has proposed a grounding function arch type electric pole having a conductive concrete layer that can overcome the problems of conventional electric poles. .
그러나, 상기와 같은 접지기능을 갖는 아치형 전주근가는 전주근가의 하부에 금속의 접지판이 위치하게 되므로 생산성이 매우 떨어지는 단점을 갖고 있는 것인데, 상기와 같은 아치형 전주근가의 경우 별도의 성형틀로부터 자동 생산되는 구조를 갖고 있는 것이고 상기의 성형틀은 아치형 전주근가가 갖고 있는 형상의 특징으로 인해 양측 분할형의 성형틀을 채택하고 있는 것인데, 양측 분할형 성형틀을 이용하여 상기의 접지판을 안치하여 작업하기에는 성형틀의 구조가 매우 복잡해지면서도 불량률의 상승이 예상되는 동시에 작업자의 실수가 발생하는 경우에는 성형틀에 대한 파손으로 연결될 수 있어 자동 생산이 불가능한 문제점을 갖고 있는 것이다.However, the arched electric pole root having the grounding function as described above has a disadvantage in that productivity is very low because the metal ground plate is located at the lower part of the electric pole root, and the arched electric pole root is automatically produced from a separate molding frame. The above mold is adopting the split mold of both sides due to the shape of the arc-shaped pole, and the work is carried out by placing the ground plate using the split mold of both sides. In the following, the structure of the mold is very complicated, but the failure rate is expected to increase, and at the same time, if a mistake of the operator occurs, it may lead to breakage to the mold, and thus automatic production is not possible.
이에 따라 상기와 같은 접지판을 갖는 아치형 전주근가는 대부분 수작업에 의존하여 생산할 수 밖에 없어 생산성이 매우 떨어지는 것이고, 생산성 저하는 결국 인건비의 상승 및 일일 생산량의 저하로 연결되므로 극히 비경제적인 것이다.As a result, the arcuate pole head having the ground plate as described above is mostly economically produced because it can only be produced depending on manual labor, and the productivity decrease is ultimately uneconomical because it leads to an increase in labor costs and a decrease in daily output.
또한, 상기와 같은 접지판에 의한 아치형 전주근가는 비교적 고가의 도전성 콘크리트와 접지판을 동시에 사용하게 되므로 제조원가가 매우 높아 경제성이 떨어지는 것이 사실이다.In addition, the arc-shaped pole pole by the ground plate as described above is a fact that the use of relatively expensive conductive concrete and ground plate at the same time is very expensive manufacturing cost is low.
특히, 상기의 접지판은 비교적 얇은 두께의 동판 등으로 이루어져 있기 때문에 접지리드선과 접지판을 용접하는 과정에서 접지판의 열변형으로 인해 천공이 형성되거나 용접이 견고하게 이루어지지 않을 뿐만 아니라 용접 작업이 매우 더디고 균일하게 이루어지지 못하는 단점을 갖고 있는 것이다.In particular, since the ground plate is made of a copper plate having a relatively thin thickness, in the process of welding the ground lead wire and the ground plate, not only a perforation is formed or a welding is performed due to thermal deformation of the ground plate, but also welding is performed. It has the disadvantage of not being very slow and uniform.
본 발명은 전기한 바와 같은 문제점을 개선한 것으로서, 아치형 전주근가의 하부 바닥면에 위치하는 도전성 콘크리트층에 금속조각을 혼합하여 성형하고, 상기 도전성 콘크리트층은 전주근가 내부의 보강철근과 접속되게 하며, 별도의 리드선은 상기 보강철근과 연결되도록 구성하여, 기존의 접지기능을 갖는 아치형 전주근가가 갖고 있던 제반의 문제점을 합리적으로 극복한 바닥면에 도전성 콘크리트층의 접지기능을 갖는 아치형 전주근가를 제공함에 본 발명의 목적이 있는 것이다.The present invention is to solve the problems as described above, and to form a mixture of metal pieces in the conductive concrete layer located on the bottom bottom of the arcuate poles, the conductive concrete layer is to be connected to the reinforcing bars inside the poles The separate lead wire is configured to be connected to the reinforcing bar, thereby providing an arc-shaped pole pole having a grounding function of a conductive concrete layer on the floor surface that reasonably overcomes all the problems of the arch-type pole pole having a conventional grounding function. It is an object of the present invention.
상기한 바와 같은 목적을 달성하기 위한 본 발명은, 기존의 접지기능을 갖는 아치형 전주근가에 있어서, 아치형 전주근가의 내부에 보강철근을 내입하여 구성하고, 그 아치형 전주근가의 하부에는 도전성 콘크리트층을 형성하여 구성하되,The present invention for achieving the object as described above, in the arch-shaped pole pole having a conventional grounding function, the reinforcing steel is built in the interior of the arch-shaped pole pole, the lower portion of the arch-shaped pole pole conductive concrete layer Form and configure,
상기 보강철근의 하부 끝단은 도전성 콘크리트층 내에 위치하여 서로 접속되고, 상기 보강철근에는 별도의 리드선을 연결하여 그 리드선이 아치형 전주근가의 외측으로 인출되게 하며, 상기 도전성 콘크리트층에는 금속조각을 혼합 성형하여 이루어지는 것이다.The lower ends of the reinforcing bars are located in the conductive concrete layer and connected to each other. The separate reinforcing bars are connected to the reinforcing bars so that the lead wires are drawn out to the outside of the arcuate pole. The conductive concrete layer is formed by mixing metal pieces. It is done by.
본 발명은, 도전성 콘크리트와 일반 콘크리트만으로 성형이 이루어지므로 기존 아치형 전주근가의 자동화 설비를 그대로 적용시킬 수 있어 대량 생산에 매우 적합함은 물론 불량이 거의 발생하지 않아 매우 경제적인 것이고, 도전성 콘크리트층 내부의 금속조각은 도전성 콘크리트층에 대한 접지 성능을 가일층 향상시켜 접지 저항의 저감 효과가 매우 뛰어난 것이며, 굵은 보강철근에 리드선을 직접 용접함에 따라 용접 작업이 빠르고 쉽게 이루어지면서도 용접 불량이 발생하지 않는 것이고, 고가의 접지판을 사용하지 않고도 접지 효율은 향상되고 생산 원가는 크게 절감되므로 매우 효율적인 것이다.In the present invention, since the molding is made of only conductive concrete and general concrete, it is possible to apply the automated equipment of the existing arch-shaped pole house as it is, so it is very economical because it is very suitable for mass production and hardly any defects occur. The metal piece of is to improve the grounding performance to the conductive concrete layer further and it is very effective to reduce the ground resistance, and the welding work is quick and easy by welding the lead wire directly to the thick reinforcing bar, and no welding defect occurs. This is very efficient because the grounding efficiency is improved and the production cost is greatly reduced without using expensive ground plane.

이하 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 상세히 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명에 따른 바닥면에 도전성 콘크리트층의 접지기능을 갖는 아치형 전주근가에 대한 전체 사시도이고, 도 2는 본 발명에 따른 바닥면에 도전성 콘크리트층의 접지기능을 갖는 아치형 전주근가에 대한 측단면도이다.1 is an overall perspective view of the arcuate pole pole having a grounding function of the conductive concrete layer on the bottom surface according to the present invention, Figure 2 is an arcuate pole pole having a grounding function of the conductive concrete layer on the bottom surface according to the present invention Side cross section view.
도시와 같이 본 발명에 따른 아치형 전주근가(10)는 내부에 보강철근(20)이 매립 형태로 위치하게 되는 것이고, 상기 아치형 전주근가(10)의 저면에는 도전성 콘크리트층(30)이 밀착 형성되어 있는 것이다.As shown in the figure, the arcuate pole pole 10 according to the present invention is to be located in the form of reinforcement reinforcement 20 in the interior, the bottom of the arch pole pole 10 is a conductive concrete layer 30 is formed in close contact It is.
이때, 상기의 보강철근(20)은 아치형 전주근가(10)의 외형에 따라 절곡 및 용접 형성되어서 그 아치형 전주근가(10)의 내구성을 증대시키기 위한 목적으로 사용되는 것이고, 상기의 도전성 콘크리트층(30)은 특수한 탄소입자와 시멘트를 주성분으로 하여 2~3일 내에 일반 시멘트 및 콘크리트의 강도와 비슷한 강도로 굳어져 탄소 고체의 형태가 되는 것으로서, 땅 속에서는 부식이 되지 않고 물에 녹지 않아 반영구적인 접지 전극으로 사용되는 것이다.At this time, the reinforcing bar 20 is bent and welded according to the outer shape of the arcuate pole pole 10 is used for the purpose of increasing the durability of the arcuate pole pole 10, the conductive concrete layer ( 30) is composed of special carbon particles and cement, and hardens to a strength similar to that of general cement and concrete within two to three days to form a carbon solid, which does not corrode in the ground and does not dissolve in water. It is used as an electrode.
특히, 상기의 도전성 콘크리트층(30)는 내부에 다수의 금속조각(50)(50')이 포함되어 있는 것으로서, 상기의 금속조각(50)(50')은 전도성이 뛰어난 철이나 구리 또는 동, 알루미늄을 절단 또는 분쇄하여 만들어지는 것으로, 형상은 분말상태 그대로 또는 가는 철사를 절단한 것과 같은 모양이나 사각형상의 조각 또는 파이프와 같은 형태 등 다양한 크기와 모양으로의 구성이 가능한 것이다.In particular, the conductive concrete layer 30 is a plurality of metal fragments 50, 50 'is contained therein, the metal fragments 50, 50' is a highly conductive iron or copper or copper It is made by cutting or crushing aluminum, the shape can be configured in a variety of sizes and shapes, such as the shape of a powder or cut thin wire, or the shape of a square piece or pipe.
또한, 상기의 도전성 콘크리트층(30)은, 도전성 콘크리트 85~95중량%와 금속조각(50)(50') 5~15중량%를 서로 혼합하여 이루어지는 것으로서, 상기의 금속조각(50)(50')에 대한 함량이 초과하는 경우에는 접지 효율은 상승하나 도전성 콘크리트층(30)의 양생 과정에서 균열 등이 발생할 수 있어 적합하지 않은 것이고, 금속조각(50)(50')에 대한 함량이 미달되는 경우에는 접지 효율의 상승 효과가 미약하기 때문에 상기와 같은 범위 내에서 중량 비율을 유지하는 것이 바람직할 것이다.In addition, the conductive concrete layer 30 is formed by mixing 85 to 95% by weight of the conductive concrete and 5 to 15% by weight of the metal pieces 50 and 50 ', and the metal pieces 50 and 50 described above. If the content of ') is exceeded, the grounding efficiency is increased, but cracking may occur during curing of the conductive concrete layer 30, which is not suitable, and the content of the metal fragments 50 and 50' is insufficient. In this case, since the synergistic effect of the grounding efficiency is weak, it will be desirable to maintain the weight ratio within the above range.
특히, 상기와 같은 보강철근(20)에는 별도의 리드선(40)에 용접되어 있는 것으로서, 상기의 리드선(40)은 전주 내부의 리드선과 연결되도록 하기 위한 것이다. 이때, 상기의 보강철근(20)은 철재를 절곡 형성하여 만들어진 것이므로 리드선(40)을 용접하는 작업이 매우 안정되고 용이하게 이루어질 수 있는 것이다.In particular, the reinforcing bar 20 as described above is to be welded to a separate lead wire 40, the lead wire 40 is to be connected to the lead wire inside the pole. At this time, since the reinforcing bar 20 is formed by bending the steel material, the welding of the lead wire 40 can be made very stable and easy.
이에 따라, 상기와 같이 리드선(40)이 용접된 상태의 보강철근(20)을 성형 파렛트 상에 올려놓은 상태에서 먼저 도전성 콘크리트를 성형틀 내에 일정량 투입하고, 이어 일반 콘크리트를 성형틀 내에 가득 투입하게 되면, 보강철근(20)이 매설되면서도 하부에 도전성 콘크리트층(30)이 형성된 아치형 전주근가(10)가 완성되는 것이다.Accordingly, in the state in which the reinforcing steel 20 in the state where the lead wire 40 is welded is placed on the forming pallet as described above, conductive concrete is first introduced into the forming mold, and then general concrete is filled into the forming mold. When the reinforcing bar 20 is embedded, the arcuate pole root 10 having the conductive concrete layer 30 formed thereon is completed.
특히, 상기의 보강철근(20)은 성형용 파렛트 상에 올려진 상태에서 파렛트의 상부에 위치한 성형틀 내에 도전성 콘크리트를 투입하는 과정을 거치게 되므로 결국 상기 보강철근(20)의 하단부는 도전성 콘크리트층(30) 내에 위치하게 되면서 상호 간의 접속 상태가 견고하게 이루어지게 되는 것이다.In particular, since the reinforcing bar 20 is subjected to the process of injecting the conductive concrete into the molding frame located on the upper part of the pallet in the state raised on the forming pallet, the lower end of the reinforcing bar 20 eventually has a conductive concrete layer ( 30) will be located in the connection between each other is made solid.
이에, 상기 보강철근(20)에 연결되어 아치형 전주근가(10)의 외측으로 인출된 리드선(40)에 전주의 리드선을 연결하게 되면 상기의 리드선(40)은 보강철근(20)을 포함하여 도전성 콘크리트층(30) 전체와 접속된 상태를 갖게 되므로 접지 효율이 크게 향상될 수 있는 것이다.Accordingly, when the lead wire 40 is connected to the lead wire 40 connected to the reinforcing bar 20 and drawn out to the outside of the arcuate pole pole 10, the lead wire 40 may include the reinforcing bar 20. Since the concrete layer 30 is connected to the entire state, the grounding efficiency can be greatly improved.
따라서, 도 3의 도시와 같이 지표면 아래 0.5m 정도의 깊이에 설치하는 전주근가 및 더욱 견고한 전주의 근입 보강을 위해 전주 밑둥에서 0.2m 정도의 상부에 체결 상태로 매립하는 기초(ROOT)근가로 사용되는 본 발명의 아치형 전주근가(10)를 체결한 후 아치형 전주근가(10)의 리드선(40)과 전주의 리드선이 연결되게 한 상태에서 전주의 하단과 아치형 전주근가(10)를 지중 매설하게 되면, 안정적이고 우수한 접지 능력을 유지할 수 있게 되는 것이다.Therefore, as shown in FIG. 3, the root pole installed at a depth of about 0.5 m below the ground surface, and used as a root (ROOT) root which is buried in a fastened state at an upper portion of about 0.2 m from the bottom of the pole in order to reinforce the firmer pole entry. When the lead wire 40 of the arcuate pole pole 10 and the lead wire of the pole pole are connected to each other after fastening the arcuate pole pole 10 of the present invention, the underground pole and the arch pole pole 10 are buried underground. Therefore, it is possible to maintain a stable and excellent grounding ability.
또한, 전기한 바와 같은 생산 과정을 거치게 되므로 기존의 아치형 전주근가(10)를 생산하기 위한 자동화 설비를 그대로 이용할 수 있어 매우 합리적인 것이고, 고가의 금속 접지판을 사용하지 않아도 되므로 매우 경제적인 것이며, 리드선의 용접 작업이 빠르고 균일하게 이루어질 수 있으므로 작업 효율성이 크게 향상되는 것이다.In addition, the production process as described above is very reasonable because it can be used as an automated equipment for producing the existing arch-shaped pole root 10 is very reasonable, it is very economical because you do not need to use expensive metal ground plate, lead wire The welding work can be done quickly and uniformly, which greatly improves the work efficiency.
