본 발명은 전주를 세울 지점의 굴착공정부터 시작하여 근가 매설과 발판볼트 및 전주번호 탈부착까지의 일련의 공정을 말하는 가공선로용 건주공사에 있어서 오거크레인용 확장형 굴착유니트를 이용한 가공선로 건주공사 시공법에 관한 것이다.The present invention is a construction process for construction of a construction line using an expansion type excavation unit for auger crane in dry construction for overhead line, which refers to a series of processes from the excavation process at the point where the pole is to be erected, to the near-floor embedding, scaffolding bolt, and the removal of the pole number. It is about.

건주공사 방법에는 인력시공을 비롯하여 백호우 및 오거크레인을 이용한 기계화 공법이 행해지고 있다. In the construction method of dry construction, the mechanization method using backhoe and auger crane is performed as well as manpower construction.

이 중 오거크레인을 이용한 건주공사가 가장 보편적인 시공법이라 할 수 있는데, 그 공정을 살펴보면 오거크레인을 이용해 근입 깊이만큼(16M 전주의 경우 2.5m 이상) 굴착을 하고 전주를 굴착한 구덩이에 삽입하여 세운 후 전주근가를 설치하기 위하여 백호우 또는 인력으로 전주근가 삽입이 가능하도록 도1의 도시와 같이 (A)부분만큼 추가 굴착하여 전주근가를 설치하고 되메우기를 하는 형태로 공사가 이루어진다.Among them, dry construction using auger crane is the most common construction method. When looking at the process, excavation is carried out using auger crane (2.5m or more for 16M Jeonju) and the Jeonju is inserted into an excavated pit. In order to install the Jeonju roots, the construction is done in such a way as to excavate as much as part (A) to install the Jeonju roots and backfill them so that the Jeonju roots can be inserted into the backhoe or manpower.

하지만 이때 사용되는 전주근가는 그 길이가 1.2m로 근가를 매설하기 위해 오거크레인 외에 추가 굴착해야 할 면적이 상당하며, 전주근가를 평행 또는 교차하여 2개를 설치해야 하는 경우에는 전주가 세워진 주변의 토양 대부분을 도 2의 (A)부분만큼 추가 굴착해야 하는 것이 현실이다. However, the Jeonju root used at this time has a length of 1.2m, and it requires a lot of additional excavation in addition to the auger crane in order to bury the foundation.When two poles are installed in parallel or crossing the Jeonju root, In reality, most of the soil needs to be additionally excavated as shown in part (A) of FIG. 2.

즉, 오거크레인을 이용하여 건주공사를 하더라도 전주근가 매설을 위하여 별도의 백호우 장비나 그에 상당하는 인력이 추가로 투입되어야 건주공사가 마무리되는 것이며, 복잡한 공정으로 인해 건주공사를 시행함에 있어 과다한 공량이 발생되고 공사시간도 불필요하게 많이 소요되는 문제가 있었던 것이다.In other words, even if the construction works using auger cranes, additional backhoe equipment or the corresponding manpower must be additionally added for the construction of Jeonju, and the construction of the construction is completed. There was a problem that takes a lot of time unnecessarily construction.

본 발명은 전기한 바와 같은 문제점을 제거코저 발명한 것으로서, 별도의 추가 인력이나 복잡한 공정의 추가 없이 확장형 굴착유니트의 확장과 축소에 의한 2단의 계단식 굴착에 의해 추가 굴착 없이 굴착공정이 용이하면서도 되메우기 시에도 소량의 토사로 전주의 견고한 매립과 근가 매설이 가능하게 하여 작업효율이 상승되게 함에 본 발명의 목적이 있는 것이다.The present invention has been made to eliminate the problems described above, it is easy to refill the excavation process without additional excavation due to the two-stage stepping excavation by expansion and contraction of the expandable excavation unit without the addition of additional manpower or complicated process It is an object of the present invention to enable solid landfilling and near-floor embedding of Jeonju with a small amount of soil.

이하, 본 발명의 시공방법을 각 공정별 실시예에 의하여 상세히 설명한다.Hereinafter, the construction method of the present invention will be described in detail by examples of each process.

도 3a는 1단계 굴착공정 설명도로서, 확장 및 축소가 가능한 확장형 유니트(1)를 장착한 오가크레인(2)을 회전시켜 굴착하되 그 굴착유니트를 좌우로 최대 확장하여 전주를 세울 지점의 굴착을 시작한다. 굴착시 확장형 굴착유니트를 확장하여 사용하면 1차 구덩이(3)의 직경이 0.8m까지 커지게 되고, 굴착 깊이는 전주근가를 매설하기 위한 최소 깊이(약 0.7m, 전주근가는 근가의 윗면이 지표면 이하 0.5m정도 되도록 해야함)까지만 굴착하여 1단계 굴착공정을 마친다. FIG. 3A is an explanatory diagram of a one-stage excavation process, in which excavation is performed by rotating an organ crane 2 equipped with an expandable unit 1 capable of expansion and contraction, but the excavation unit is extended to the left and right to maximize the excavation of the pole. To start. When digging an expanded type of excavation unit, the diameter of the primary pit (3) is increased to 0.8m, and the depth of excavation is the minimum depth (about 0.7m) for embedding the main pole value. Excavation only up to 0.5m) to complete the first stage excavation process.

도 3b는 2단계 굴착공정 설명도로서 1단계 굴착공정을 마친 다음, 확장형 굴착유니트를 다시 원위치로 축소하여(직경 0.45m) 처음 굴착한 지점에 오거크레인(2)을 이용하여 전주 근입 깊이까지 원형 계단식으로 굴착을 하여 2차 구덩이(4) 굴착 작업을 마무리하면 2단의 계단식 원통형의 구덩이가 형성되는 것이다. Figure 3b is a two-stage excavation process explanatory diagram, after completing the first stage excavation process, the expansion digging unit is reduced to its original position (0.45m in diameter) using the auger crane (2) at the first excavation to the round to the depth of inlet When the second pit (4) excavation work is completed by stepping excavation is to form a stepped cylindrical pit of two stages.

도 3c는 전주의 고정 및 1단계 되메우기 공정 설명도로서, 2단계 굴착 공정 후 구덩이(3)(4)에 전주(5)를 세우고, 세워진 전주(5)를 고정하기 위하여 일부 되메우기 작업을 함에 있어 1차 굴착 시 파놓은 지점의 토사를 되메우기 용도로 이용하는 것이다. 즉 전주를 고정하기 위한 임시 되메우기 작업과 동시에 2차 굴착 지점인 2차 구덩이(4)가 가심이 되는 것이다. 3c is a diagram illustrating the fixing of the pole and the first-stage backfilling process, after the two-stage excavation process, the poles 3 are placed in the pits 3 and 4, and some backfilling operations are performed to fix the poles 5 that are erected. It is used for backfilling the earth and sand of the excavation point during the first excavation. In other words, the secondary pit (4), which is the second excavation point at the same time as the temporary replenishment work to fix the pole is to be added.

도 3d는 1단계 굴착부인 1차 구덩이(3)의 귀따기 공정설명도로서 다음 공정에서 전주(5)에 장착될 전주근가(6)가 수직방향으로 삽입될 수 있는 최소한의 공간을 파내어 근가삽입공(7)을 형성하는 것이다. 이때 가심 작업을 하면서 전주근가가 삽입될 수 있도록 삽을 이용하여 1차 굴착 구덩이(3)의 양측을 0.2m 씩 귀를 따는 작업을 전기한 되메우기 공정 시에 함께 포함하여 작업함으로써 작업 효율성을 더욱 높일 수 있다.FIG. 3D is an explanatory diagram of ear picking of the primary pit 3, which is the first stage excavation, and excavates the minimum space where the root pole 6 to be mounted in the pole 5 in the next step can be inserted in the vertical direction. To form a ball (7). At this time, the work to be added to both sides of the primary excavation pit (3) by using the shovel to insert the jeonju root while inserting the ears at the backfilling process in addition to increase the work efficiency further Can be.

이때, 도4a, 4b의 도시와 같이 1차 구덩이의 직경보다 작은 직경을 갖는 반원형의 근가를 사용할 경우 확장 굴착된 1차 구덩이에 별도의 귀따기가 필요 없이 그대로 내입될 수 있으므로 귀따기 공정을 생략하고 곧바로 다음 공정인 근가조립공정을 통해 근가를 설치할 수 있게 된다. 또한, 근가설치 시 연약지반이거나 기타 사유로 보강이 필요한 경우에는 반원형의 근가를 도넛형태로 전주를 원형으로 감싸도록 장착하여 보강 시공을 할 수 있다.At this time, when using a semi-circular root value having a diameter smaller than the diameter of the primary pit as shown in Figures 4a, 4b can be embedded in the expanded excavated primary pit without additional ear picking, so the ear picking process is omitted Immediately, the work price can be established through the work price assembly process. In addition, when reinforcement is required for installation of soft ground or other reasons, reinforcement may be carried out by mounting the semicircular root price in a donut shape to wrap the pole in a circular shape.

또한 여기에서 확장형 굴착유니트의 크기를 크게 개발하여 기존 전주근가의 크기에 맞도록 직경 1.2m의 원형 굴착이 가능하나, 이 경우 불필요한 토사의 굴착이 많아지고 건주 후 근가의 기능이 저하되어 장력이 받는 쪽의 원토를 약 0.2m 정도만 무너뜨려 시공하므로서 큰 장력에 견디도록 굴착 구덩이 양측 귀를 따는 작업을 하는 것이다.In addition, it is possible to develop a large sized excavation unit here, so that a circular digging with a diameter of 1.2m can be made to meet the size of the existing total roots. Plowing only about 0.2m of the soil on the side of the construction is to work to pick the ears of both sides of the excavation pit to withstand the large tension.

도 3e는 전주의 근가 조립공정설명도로서 위의 공정에서 귀따기 공정까지 완료도면 전주근가(6)를 근가삽입공(7)을 통하여 전주(5)에 수직방향으로 삽입하여 장착위치에 두고 U-볼트(8)를 이용하여 전주에 장착한 후 최종 되메우기 작업을 하면 모든 공정이 마무리되는 것이다. Figure 3e is an explanatory drawing of the pole value assembly process of the pole pole, the complete drawing from the above process to the ear picking process, the pole pole 6 is inserted into the mounting position vertically to the pole pole (5) through the insertion hole (7) to put the U -When the bolt (8) is mounted on the pole and the final backfilling work, all the processes are finished.

이상과 같이 본 발명은 가공선로용 건주공사를 시공함에 있어서, 별도의 추가 인력이나 복잡한 공정의 추가 없이 확장형 굴착유니트의 확장과 축소에 의한 2단의 계단식 굴착에 의해 추가 굴착 없이 굴착공정이 용이하면서도 되메우기 시에도 소량의 토사로 전주의 견고한 매립과 근가 매설이 가능하게 하여 작업효율이 상승되게 한 효과가 있는 것이다.As described above, the present invention is easy to perform the excavation process without additional excavation by the two-stage stepping excavation by expansion and contraction of the expandable excavation unit without the addition of additional manpower or complicated process in the construction of the dry construction for the processing line Even when refilling, small amount of earth and sand can make the landfilling and landfilling of Jeonju more effective.
