일반적으로, 소구경 터널 굴진작업을 위한 추진공법은 도 1에 도시된 바와 같이 마이크로 터널링 머신(micro tunneling machine) 또는 세미 실드 머신(semi-shield machine)이라는 강재 원통형의 굴진기(20)를 수직 추진갱(T) 내에 투입시켜 기계 선단부에 장착되어 있는 토사굴착용 커터 헤드(22a: cutter head)를 회전시키면서 지반을 굴착하고 막장면에 각종 보조공법(약액주입)을 실시하여 막장면의 붕괴를 방지하면서 터널 굴진기(20)의 후방부에 설치된 추진관(30)을 하나씩 유압방식의 추진기(10)로 압입, 추진시키는 작업을 반복하면서 도달기지의 수직 도달갱(T')에 이르는 터널을 굴착하는 방법이다. In general, the propulsion method for the small diameter tunnel drilling operation is to vertically push the steel cylindrical excavator 20, called a micro tunneling machine (semi-shielding machine) or a semi-shielding machine as shown in FIG. Excavate the ground while rotating the cutter head (22a), which is inserted into the pit T and mounted on the tip of the machine, to prevent the collapse of the membrane surface by applying various auxiliary methods (chemical injection) to the membrane surface. While repeating the operation of pressing and pushing the propulsion pipes 30 installed at the rear of the tunnel excavator 20 into the hydraulic propeller 10 one by one, excavating the tunnel reaching the vertical reach shaft T 'of the reach base. That's how.

상기의 방식에 의한 종래의 추진기(100)는 도 2에 도시된 바와 같이 일정 깊이와 폭을 갖는 수직 추진갱(T) 바닥에, 소구경 터널의 굴착위치와 일치되도록 설 치되고, 직사각형태의 틀 양측 상단면에 슬라이딩 면(120)이 형성되며, 그 슬라이딩 면(120) 상에 소정 등간격으로 장착공(130)이 서로 마주하게 배열 형성된 추진기 베이스 프레임(110)과;The conventional propeller 100 according to the above method is installed at the bottom of the vertical propulsion shaft T having a predetermined depth and width as shown in FIG. Sliding surface 120 is formed on the upper surface of both sides of the frame, and the propeller base frame 110 is formed on the sliding surface 120, the mounting holes 130 are arranged to face each other at a predetermined equal interval;

상기 추진기 베이스부(110)의 슬라이딩 면(120)에 안착되고, 굴진기(20) 또는 추진관(30)의 일측을 고정하기 위한 추진벽(140)이 입설되며, 그 추진벽(140)의 후방 양측에 유압실린더(150)가 구성된 추진기 몸체부와;The propulsion wall 140 is mounted on the sliding surface 120 of the propeller base part 110 to fix one side of the excavator 20 or the propulsion pipe 30. A thruster body part configured with hydraulic cylinders 150 at both rear sides thereof;

상기 슬라이딩 면(120) 상에 형성된 장착공(130)에 끼워 설치되며, 유압실린더(150)의 로드(150a)가 전진 추진력이 발생되도록 반발력을 제공하는 스토핑 블록(160)으로 구성된다. Installed in the mounting hole 130 formed on the sliding surface 120, the rod 150a of the hydraulic cylinder 150 is composed of a stopping block 160 to provide a repulsive force to generate a forward driving force.

그러나, 이와 같은 종래의 굴진기용 추진기는 다음과 같은 문제점이 있다. However, such a conventional excavator propeller has the following problems.

첫째, 상기 종래의 추진기는 유압실린더의 배치구조가 수평방향으로 서로 나란하게 되어 있기 때문에 추진기의 폭이 커지고, 둘째, 상기 종래의 추진기의 유압실린더는 상기의 배치구조의 문제점에 의해 비교적 큰 용량의 유압실린더만을 적용 했어야 했다.First, the conventional propeller has a larger width of the propeller since the arrangement of the hydraulic cylinders are parallel to each other in the horizontal direction. Second, the hydraulic cylinder of the conventional propeller has a relatively large capacity due to the problems of the arrangement. Only hydraulic cylinders should have been applied.

위와 같은 이유 때문에 수직 추진기지가 커야만 했고, 작업장소가 협소하거나 복잡한 도심에서 추진공법을 적용하는데 있어 많은 제약이 되어왔다.For this reason, the vertical propulsion base had to be large, and there have been many restrictions on the application of the propulsion method in narrow or complex urban areas.

따라서, 본 발명은 상기의 문제점을 해결하기 위해 창출된 것으로서, 그 목적은 소구경 터널을 굴착하기 위해 굴진기를 굴착방향으로 추진하는 추진장치의 유 압실린더 배치구조를 개선하여 좁은 수직 추진갱에서 공간활용도를 극대화하는 굴진기용 추진장치를 제공함에 있다. Accordingly, the present invention has been made to solve the above problems, the object of which is to improve the hydraulic cylinder arrangement of the propulsion device for pushing the excavator in the excavation direction to excavate a small diameter tunnel space in a narrow vertical propulsion shaft An object of the present invention is to provide an excavator propulsion device for maximizing utilization.

이상에서와 같은 본 발명을 적용하게 되면, 유압실린더의 배치형태를 수평방향이 아니라 마주보는 방향에서 일정 경사지게 배치하였기 때문에 수평선상을 기준으로 볼 때 장치의 폭이 현저히 감소되어, 현저히 작은 추진기지에서의 추진시공이 가능해졌고 공간활용 측면 뿐만 아니라 작업자의 동선도 크게 개선되어 안전사고의 발생률을 줄일 수 있는 효과가 있다.
