오거(Auger)란 흙 속에 비교적 간단하게 구멍을 뚫는 도구로, 여러 가지 형상을 한 비트를 로드의 선단에 부착하고, 회전하면서 흙 속에 압입하여 파낸 흙을 지상으로 끌어 올린다. 오거의 회전과 압입을 제공하는 방법으로 핸드 오거와 기계 오거가 있다. 또한 비트의 형상에는 토질에 따라 구별하여 사용할 수 있도록 여러 가지의 것이 있지만, 기계 오거에서는 주로 스크루식이 사용된다.Auger is a relatively simple tool for drilling a hole in the soil. Bits with various shapes are attached to the tip of the rod, and while rotating, it presses into the soil and lifts the dug up soil to the ground. There are hand augers and mechanical augers as methods of providing rotation and press fit of the auger.

일반적으로, 철근 콘크리트 구조물이나 그 밖의 다양한 건축물 등을 지표면 위에 축조하고자 하는 경우, 이러한 구조물이나 건축물 등은 하중을 기초에 의해 지반이나 암반으로 전달하도록 하기 위하여, 지중에 PHC, 강관파일, H형 빔 또는 파일 등을 일정 간격으로 박아 매설하는 방법으로 기초 공사를 실시한다.In general, when a reinforced concrete structure or various other structures are to be built on the ground surface, such structures or structures are PHC, steel pipe piles, H-beams in the ground in order to transmit the load to the ground or rock by the foundation. Alternatively, the foundation work is carried out by driving piles, etc. at regular intervals and burying them.
토목 공사에 있어서, 구조물의 안정성 확보를 위하여 선행적으로 수행되는 기초 공사는 1층 바닥선 아래의 건축물 구조체를 완성하기 위한 토공사를 말한다. 특히, 지반이 연약지반인 경우, 건물 상부에서 전달되는 하중을 분산시켜 지반의 지내력을 확보함으로써, 침하량의 최소화 및 부동침하의 발생을 방지할 수 있다.In civil engineering works, the foundation work carried out in advance to ensure the stability of the structure refers to the earthworks to complete the building structure below the floor line of the first floor. In particular, when the ground is soft ground, by dispersing the load transmitted from the upper part of the building to secure the bearing capacity of the ground, it is possible to minimize the amount of settlement and prevent the occurrence of floating settlement.
이를 위해, 지반과 그 상부의 기둥 또는 벽체 사이에 말뚝(pile)과 같은 구조물이 설치될 수 있다. 말뚝은 지반의 암반층까지 도달하여 단단한 암반으로부터 지내력을 확보할 수 있다.To this end, a structure such as a pile may be installed between the ground and a column or wall thereon. The pile can reach the bedrock layer of the ground and secure bearing capacity from the hard bedrock.
말뚝을 심기 위해서는 지반 깊숙히 천공(drilling, boring) 작업이 수행되어야 하고, 이 때 오거(auger)가 사용될 수 있다. 오거는 비트를 로드의 선단에 부착하고, 회전하면서 흙 속에 압입되어 구멍을 뚫는다. 기존의 오거는 회전하는 선단과 접촉하는 흙을 긁어 잘게 부수고, 자중에 의한 압력으로 땅 속으로 진행하는 것이 일반적이다.In order to plant piles, drilling or boring work should be performed deep into the ground, and an auger may be used in this case. The auger attaches the bit to the tip of the rod, and as it rotates, it is pressed into the soil to make a hole. Conventional augers scrape the soil in contact with the rotating tip and crush it, and it is common to proceed into the ground under pressure by its own weight.

이러한 본 발명에 따르면, 종래기술과 같이 오거와 케이싱오거가 같은방향으로 회전하게 되면 하부에서 굴착된 토사를 외부로 토출할 수 없는데 반하여, 본 발명은 오거와 케이싱오거가 동시에 회전하면서도 그 회전방향을 반대방향으로 형성되게 함에 따라 보다 신속하게 천공 작업이 수행될 수 있다. According to the present invention, as in the prior art, when the auger and the casing auger rotate in the same direction, the excavated soil cannot be discharged to the outside, whereas the present invention changes the direction of rotation while the auger and the casing auger rotate at the same time. By having them formed in the opposite direction, the drilling operation can be performed more quickly.
또한, 오거와 케이싱 오거가 하나의 회전방향으로 회전하는 종래기술의 경우, 오거 천공 후 다시 케이싱을 삽입하고, 그 후에 다시 천공해야하는 공정이 진행되어야 했으나, 본 발명은 오거와 케이싱오거가 서로 반대방향으로 회전함에 따라 상기의 공정을 동시에 진행가능하여 공정단축에 따른 작업의 용이성 및 작업속도가 급격히 향상되는 효과가 있으며, 기존 공정에 필요하던 추가의 크레인 등의 장비 대여료를 절감할 수 있어 경제적인 효과도 있다. In addition, in the case of the prior art in which the auger and the casing auger rotate in one rotational direction, the process of inserting the casing again after drilling the auger, and then drilling again should be performed, but the present invention provides that the auger and the casing auger are opposite to each other As it rotates, the above processes can be carried out simultaneously, so the easiness of work and work speed are sharply improved due to the shortening of the process, and the cost of rental of additional equipment such as cranes required for the existing process can be reduced, which is economical. there is also
또한, 기존은 오거와 케이싱오거를 반대방향으로 회전시키는 장비의 경우에는 오거와 케이싱오거를 구동하는 각각의 개별적인 감속기 또는 장치를 구비함에 따라 장비의 운전이 복잡해지며 추가로 투입되는 장치 및 자재에 따른 비용이 상승하게 되나, 본 발명의 경우 감속기 하나의 구동으로 오거와 케이싱오거를 동시에 개별적으로 반대방향으로 회전시킴으로써 운전이 간편하고 생산비용을 절감할 수 있는 효과가 있다. In addition, in the case of the conventional equipment that rotates the auger and the casing auger in the opposite direction, the operation of the equipment becomes complicated as each individual reducer or device for driving the auger and the casing auger is provided, and the operation of the equipment becomes complicated depending on the equipment and materials added additionally.

본 발명의 일 실시 예에 따른 본 더블 케이싱오거 구동 감속기(1)의 작동을 살펴보자면, 상기 고정브라켓(100)을 통하여 본 장치의 상부는 감속기(10)와 고정되며, 메인샤프트(200)의 일단이 감속기(10)의 축과 결합한다. 상기 메인샤프트(200)의 타단은 오거(20)와 결합한다. 이와같이, 단순하게 오거(20)만 결합하여 사용가능하다. Looking at the operation of the double casing auger driving reducer 1 according to an embodiment of the present invention, the upper portion of the device is fixed to the reducer 10 through the fixing bracket 100 , and the main shaft 200 One end is coupled to the shaft of the reducer (10). The other end of the main shaft 200 is coupled to the auger 20 . In this way, it is possible to simply combine only the auger 20 .
또다른 실시 예는, 더블 케이싱오거 구동 감속기(1)에 감속기(10)와 오거(20)가 결합된 상태에서 오거(20)를 내포하면서 스커트(400)와 케이싱오거(500)가 결합하게 되면, 케이싱오거(500)와 오거(20)를 동시에 사용가능하다. 이 경우, 메인샤프트(200)에 연결된 오거(20)와 링기어(330)에 연결되어 있는 스커트(400)에 결합되어 있는 케이싱오거(500)는 서로 반대방향의 회전을 가지게 된다. In another embodiment, the skirt 400 and the casing auger 500 are coupled while the auger 20 is contained in a state in which the reducer 10 and the auger 20 are coupled to the double casing auger driving speed reducer 1 . , it is possible to use the casing auger 500 and the auger 20 at the same time. In this case, the auger 20 connected to the main shaft 200 and the casing auger 500 coupled to the skirt 400 connected to the ring gear 330 rotate in opposite directions.
이와 같이 오거(20)와 케이싱오거(500)가 서로 반대방향으로 회전하며 천공하는 경우, 천공하는 효율이 상승함과 더불어 만약 일체형으로 오거(20)와 케이싱오거(500)가 같은 방향으로 회전하게 되는 경우, 굴착된 토사를 외부에 배출되기 힘드나, 본 장치의 경우 케이싱오거와 오거는 항상 반대방향으로 회전하게 됨에 따라 굴착된 토사가 배출구를 통하여 보다 원활하고 신속하게 배출되게 되는 장점이 있다. As such, when the auger 20 and the casing auger 500 rotate in opposite directions and drilling is performed, the drilling efficiency is increased and if the auger 20 and the casing auger 500 are integrally rotated in the same direction In this case, it is difficult to discharge the excavated soil to the outside, but in the case of this device, the casing auger and the auger always rotate in opposite directions, so that the excavated soil is discharged more smoothly and quickly through the outlet.
또한, 천공시에 압축공기 공급 등이 필요한 경우에는 오거(20) 및 케이싱오거(500)의 움직임과 상관없이 고정되어 있는 상기 쇼벨커버(211)에 구비된 쇼벨커버홀(212)과 연결하여 손쉽게 압축공기를 공급하며 작업이 가능하다. In addition, when it is necessary to supply compressed air during drilling, it is easily connected to the shovel cover hole 212 provided in the shovel cover 211 fixed regardless of the movement of the auger 20 and the casing auger 500 . Compressed air is supplied and work is possible.
이에 더하여, 케이싱오거(500)가 굴착된 토사에 삽입된 상태에서 감속기의 간단한 조작으로 스커트(400)를 회전 및 상승하게 함으로써 파이핑 삽입작업도 동시에 이루어 질 수 있다. In addition, the piping insertion operation can be simultaneously performed by rotating and raising the skirt 400 by a simple operation of the reducer in a state in which the casing auger 500 is inserted into the excavated soil.
