접지저항 저감제 주입용 툴 및 그 툴을 이용한 접지저항 저감제 시공방법{Construction Method of Ground Resistance Reduction Agent Using Ground Resistance Reducing Agent Injection Tool}A tool for injecting a grounding resistance reducing agent and a method for constructing a grounding resistance reducing agent using the tool

본 발명은 접지저항 저감제 주입용 툴과 상기 툴에 접지봉 1개 이상을 수직으로 연결 시키면서 타격에 의해서 지중에 매설함과 동시에 접지봉 주변으로 접지저항 저감제가 공급될 수 있도록 구성된 툴과 상기 툴을 이용한 접지저항 저감제 시공방법에 관한 것이다.The present invention uses a tool for injecting a grounding resistance reducing agent and a tool configured to vertically connect one or more grounding rods to the tool and to be able to supply a grounding resistance reducing agent around the grounding rod while burying it in the ground by hitting the tool It relates to the construction method of the earth resistance reducing agent.

주지하는 바와 같이 접지봉과 접지저항 저감제는 철탑, 배선선로 전주 등 각종 전기 시설물에서 발생하는 전류를 받아 지중으로 방전시키는데 사용하는 것으로서, 접지봉과 접지저항 저감제를 지중에 매설하고 철탑, 배선선로 전주 등 각종 전기 시설물에 구비된 어스용 동선과 연결하여 사용한다.As is well known, the grounding rod and grounding resistance reducing agent are used to receive current generated from various electrical facilities such as iron towers and wiring line poles and discharge them underground. It is used in connection with the earth copper wire provided in various electric facilities such as

상기와 같이 접지봉과 접지저항 저감제를 지중에 매립시공하기 위해서는 먼저, 접지봉 1개 이상을 수직으로 연결시켜 지중으로 설치하고 상기 접지봉 주변에 접지저항 저감제를 넣어서 시공하는데, 이러한 시공과정을 구체적으로 살펴보면, 작업자는 철탑, 배선선로 전주 등 각종 전기 시설물로부터 일정한 거리를 두고 삽과 같은 각종 도구를 이용하여 지중으로 대략 2미터 이상의 깊이로 공간부를 확보하고, 접지봉 1개 이상을 수직으로 연결시켜 설치하는 동시에 상기 접지봉 주변에 접지저항 저감제를 넣어서 매립하기 때문에 그에 따른 노동력과 시간이 많이 소요되므로 작업 규모에 비하여 과다한 인건비가 지출되는 단점이 있다.In order to embed the grounding rod and the grounding resistance reducing agent in the ground as described above, first, one or more grounding rods are vertically connected and installed underground, and a grounding resistance reducing agent is put around the grounding bar for construction. Looking at it, the worker maintains a certain distance from various electrical facilities such as pylons, wiring lines, and electric poles, secures a space at a depth of about 2 meters or more underground using various tools such as shovels, and connects one or more grounding rods vertically to install it. At the same time, since a grounding resistance reducing agent is placed around the grounding rod and buried, it takes a lot of labor and time.

상기한 단점을 해결하기 위하여 최근에는 굴삭기의 브레이커를 이용하여 접지봉을 지면에 박아 넣는 타공작업을 통해서 접지봉을 지중에 매설하는 기술이 개시되었으나, 접지봉 주변에 접지저항 저감제를 넣을 수 없기 때문에 접지봉의 기능이 크게 떨어지는 단점이 있다.In order to solve the above shortcomings, a technique of burying a grounding rod in the ground through a drilling operation of driving the grounding rod into the ground using a breaker of an excavator has been recently disclosed. The disadvantage is that the function is greatly reduced.

상기와 같은 단점을 해결하기 위하여 천공용 스크류장치에 의해서 지중에 구멍을 천공하는 동시에 접지봉을 지중 약 2미터에서 5미터까지 매설하고, 접지봉의 주변에 형성된 공간부로 접지저항 저감제를 충진하는 시공기술이 개발되어 있다.In order to solve the above disadvantages, a hole is drilled in the ground by a drilling screw device, the ground rod is buried from about 2 to 5 meters underground, and the space formed around the ground rod is filled with a grounding resistance reducing agent. this has been developed

상기와 같은 시공을 하기 위한 천공용 스크류장치는 지중에 구멍을 천공할 수 있게 구성된 스크류와 상기 스크류의 중심에는 지중에 매설하기 위한 접지봉을 수용할 수 있는 접지봉 대기실과 그 상부에는 접지저항 저감제 공급을 위한 통로 및 유압회전장치의 회전축이 결합되도록 축공이 구성된 연결유닛과, 상기 연결유닛을 접지저항 저감제 유입관 및 고정구가 구비된 고정하우징에 설치하는 구성으로 되어 있기 때문에 그 구조가 매우 복잡하고 천공용 스크류장치를 작동시키는 장비 구입비용과 운영비용이 많이 소요되는 등의 문제가 있다.The screw device for drilling for construction as described above includes a screw configured to drill a hole in the ground, a ground rod waiting room capable of accommodating a ground rod for burial in the ground at the center of the screw, and a ground resistance reducing agent supplied to the upper portion The structure is very complicated because it consists of a connection unit having a shaft hole so that the passage and the rotation shaft of the hydraulic rotation device are coupled to each other, and the connection unit is installed in a fixed housing equipped with an inlet pipe for reducing grounding resistance and a fixture. There is a problem in that the purchase cost and operating cost of the equipment for operating the drilling screw device are high.
