본 발명은 신설도로 및 기존도로의 도로설비 건설과정에서 필요한 접지시공시 도로 법면에 오거천공 공법에 의한 접지동봉 및 고강도 저감재 지중매설 시공방법에 관한 것으로, 기존 현장설비 설치개소는 일반접지봉공법, 고강도접지판공법, 고강도접지봉공법을 기본으로 적용하되, 전 개소에 대해 대지비저항을 측정하여 적용하고 있다. 일반 접지봉을 이용한 시공방법은 접지봉의 머리가 버섯 형태로 되지 않게 하여야 하며, 피막이 되어 있는 경우 피막이 벗겨지지 않도록 조심하여 타입한다.The present invention relates to a ground rod and a high-strength reducing material underground construction method by the auger boring method on the ground surface required in the construction of road equipment on the new road and the existing road, the existing field installation point is a general ground rod method, The high strength ground plate method and the high strength ground rod method are applied as a basis, but the earth resistivity is measured and applied to all places. The construction method using a general ground rod shall not prevent the head of the ground rod from becoming a mushroom type, and if it is a coating, be careful not to peel off the coating.
접지선(연동연선)과 지표와의 간격이 75cm 이상이 되도록 지하에 매설하여야 하며, 통신용 접지시설과 수배전 시설용 지중 매설도체는 최소 10m 이상 격리되어야 한다.It should be buried underground so that the distance between the ground wire (connected twisted pair) and the ground is not less than 75cm, and the grounding conductor for telecommunication grounding facilities and water distribution facilities should be isolated at least 10m.
접지봉을 지하에 매설할 때에는 직경 30cm, 깊이 60cm의 구덩이를 파고 접지봉을 땅에 설치하되 접지봉의 머리가 구덩이의 밑바닥에서 15cm 더 들어가도록 해야하며, 접지봉용 리드선으로 지상에 연결해야 한다.When the ground rod is buried underground, a pit 30cm in diameter and 60cm in depth should be dug and the ground rod should be installed in the ground, but the head of the ground rod should be 15cm further from the bottom of the pit, and the ground rod lead should be connected to the ground.
고강도 접지판을 이용한 시공방법은 도 2에서와 같이 폭 30cm, 깊이 60cm 이상의 터파기를 하며, 현장여건에 따라 폭과 깊이 조정이 가능하다. 주접지용 GV전선과 고강도 접지판의 리드선과의 접지선 연결을 이질금속 슬리브를 사용하여 접속한 후 열수축튜브로 마감 처리한다. 접지공사 시공 후 흙으로 되메우기 작업을 한다.Construction method using a high-strength ground plate, as shown in Figure 2, the width 30cm, more than 60cm deep trench, it is possible to adjust the width and depth according to the site conditions. The ground wire connection between the main grounding GV wire and the lead wire of the high strength ground plate is connected with a heterogeneous metal sleeve and finished with heat shrink tube. After earthing construction, backfill with soil.
이러한 기존 공법에 의한 공사시 사리도 법면의 중간대지가 취약해짐에 따라 토사 유실의 위험이 발생한다. 또한 도로 법면부 작업 환경이 협소하여 작업공간을 확보하기가 어렵고 도로의 우수 측구, 암반, 옹벽등의 장애물로 인하여 시공품질 확보에 어려움이 있다. 상기 공법으로 도시 근교 및 도심지역에 도로변 통신설비를 위한 접지 공사시 주변 시설물에 대한 훼손으로 민원이 다발로 발생하여 오히려 공사기간이 장시간 지연되는 문제점이 발생하게 된다.In case of construction by the existing construction method, as the middle ground of Sarido law becomes weak, there is a risk of soil loss. In addition, due to the narrow working environment of the road front part, it is difficult to secure a working space and it is difficult to secure construction quality due to obstacles such as excellent sideways, rocks, and retaining walls. With the above method, when grounding for roadside communication facilities in urban suburbs and downtown areas, the complaints are caused by damage to the surrounding facilities, resulting in a delay in the construction period for a long time.
본 발명은 상기와 같은 기존 시공방법에 대한 문제점을 해소하기 위하여 일반접지봉 또는 고강도접지판을 사용하는 대신 오거천공 공법을 사용하여 천공을 한 후 접지동봉 지중 매설시 고강도 저감재를 병행 사용하여 시공하는 것이다.In order to solve the problems of the existing construction method as described above, instead of using a general ground rod or a high strength ground plate to perform the construction using the auger boring method to construct a ground rod enclosed in the underground buried ground using a high strength reducing material in parallel will be.
본 발명 공법으로 시공하므로서 도시근교 및 도심지역 공사시 접지공사 면적을 최소화하여 민원문제를 차단하고, 도로 법면의 녹지공간을 최소로 훼손하므로 자연 환경을 지킬 수 있다. 또한 안정되고 균일한 접지 품질을 제공하여 대지비저항의 능률을 향상시키고자 한다. 시공품질을 향상시킴과 아울러 접지 공사비를 절감하고, 공사방법을 단순화하여 작업 효율을 향상시켜 시공기간을 단축한다.The construction of the present invention can minimize the ground construction area when constructing urban suburbs and urban areas to block civil affairs problems, and to damage the green space of the road surface to a minimum, thereby protecting the natural environment. It also aims to improve the efficiency of the earth resistivity by providing stable and uniform ground quality. In addition to improving construction quality, it also reduces ground construction costs and simplifies construction methods to improve work efficiency and shorten construction period.
기존의 접지동봉과 함께 고강도 저감재를 첨가하여 대지와 일체화가 쉽고 경년변화가 거의 없어 반영구적인 접지 효과를 얻을 수 있다.By adding a high-strength reduction material with the existing ground rod, it is easy to integrate with the earth and there is almost no secular change, and thus a semi-permanent grounding effect can be obtained.
