Abstract
Description
일반적으로 강관추진공법은 강관을 지중에 압입후 관내 토사를 인력으로 굴착하여 배토시킨후 다시 추진관을 유압잭을 이용하여 관입 시키는 반복과정 통해 시공되는 비개착 굴착공법이다In general, the steel pipe propulsion method is a non-excavation excavation method that is constructed through an iterative process of injecting a steel pipe into the ground, excavating and excavating soil in the pipe with manpower, and then injecting the propulsion pipe using a hydraulic jack.
그러나 이러한 방법은 관입과정에서 대부분 지중 토질의 변화에 따라 추진관이 상,하향이나 좌,우로 선형이 틀어지게 된다.However, in this method, the propulsion pipe is linearly shifted up and down or left and right according to the change of soil soil in the penetration process.
이에 따라 상,하수도관 또는 가스관,통신,전력선등 목적물의 선형이나 레벨을 맞추기 위해 강관 추진중 사용하는 재래식의 방법은 추진시의 선도관에 도4, 도5와 같이 철판을 용접하고 추진관을 압입하여 상,하향을 유도한다Accordingly, the conventional method used during steel pipe propulsion to match the linearity or level of targets such as water, sewage pipes, gas pipes, telecommunications, power lines, etc. Indent up and down
이때 선도관에 철판을 용접하기 위해 무리하게 막장(선도관의 전방)을 굴착하게 되고 이는 토질에 따라 도로나 하천등 횡단 상부 구조물에 침하나 변형을 가져오게 되며 심하게는 종종 붕괴에 까지 이르러 산업재해로 이르게 된다At this time, to weld the steel plate to the leading pipe, the barrier (forward of the leading pipe) is forcibly excavated, which in turn causes settlement or deformation of the upper structure such as roads or rivers, depending on the soil, and often leads to collapse. Leads to
또한 용접된 부위를 레벨조정후 제거하기위해 막장을 재굴착하는등의 문제점이 발생하고 이로 인해 위험성 증가 및 공기지연, 공사비 증가를 초래하게 되는 문제점이 있다.In addition, there is a problem such as re-excavation of the membrane in order to remove the welded part after adjusting the level, which leads to increased risk, air delay, and construction cost.
본 발명은 재래식공법의 문제점을 해결하기 위해 강관을 지중에 관입하기 전에 유압슈를 장착(도 2, 도 3 참조)하여 막장을 굴착하지 않고 유압을 사용하여 레벨 및 선형을 수정토록 한다. 이를 위해 추진관의 관경에 맞게 유압슈를 제작(도 1 참조)하여 선도관에 장착후 추진시 레벨후 수시로 확인후 유압슈를 전,후진시켜 막장을 굴착하지 않고도 안전하고 빠르게 선형 및 레벨을 조정하여 정밀한 시공이 되도록 한다In order to solve the problems of the conventional method, the hydraulic shoe is mounted (see FIGS. 2 and 3) before the steel pipe is inserted into the ground so that the level and the linearity can be corrected using hydraulic pressure without digging the membrane. For this purpose, make a hydraulic shoe according to the diameter of the propulsion pipe (see Fig. 1) and install it on the leading pipe, and check the pressure at any time after the level. Precise construction

(유압슈 S2를 전진시키고 유압슈 S1을 후진하여 강관을 추진하게되면 유압슈 S2가 상향으로 토압을 받아 선도관이 상향으로 조정하게 된다)(If you advance the hydraulic shoe S2 and reverse the hydraulic shoe S1 to push the steel pipe, the hydraulic shoe S2 receives upward pressure and the leading pipe adjusts upward)

(유압슈 S1을 전진시키고 유압슈 S2을 후진하여 강관을 추진하게되면 유압슈 S1이 하향으로 토압을 받아 선도관이 하향으로 조정되게 된다)(If you advance the hydraulic shoe S1 and reverse the hydraulic shoe S2 to push the steel pipe, the hydraulic shoe S1 will receive downward pressure and the lead pipe will be adjusted downward.)

추진관의 관경에 맞게 제작된 도1의 유압슈를 추진관의 선도관에 장착후 유압호스를 통해 유압유니트(hydro unit)에 연결한후 유압슈의 전진 및 후진에 의해 추진관의 레벨 및 선형 수정을 유도한다The hydraulic shoe of FIG. 1 manufactured according to the diameter of the propulsion pipe is mounted on the leading pipe of the propulsion pipe, connected to the hydraulic unit through the hydraulic hose, and the level and linearity of the propulsion pipe by the forward and reverse of the hydraulic shoe.

산업재해를 방지한다.Prevent industrial accidents
선단부 철판용접을 위해 무리하게 굴착하던 재래식 공법과 달리 사전에 장착돤 유압슈를 리모콘에 의해 조정(작동)하기 때문에 안전시공이 되며 산업재해를 방지 할 수 있다Unlike the conventional method that used to excavate excessively for welding the tip plate, the hydraulic shoe that is installed in advance is adjusted (operated) by the remote control, which enables safe construction and prevents industrial accidents.
정밀시공이 가능하다Precision construction is possible
레벨 및 선형조정이 쉽기 때문에 수시로 확인하여 정밀시공이 되도록 할 수 있다Since level and linear adjustment are easy, it can be checked frequently for precise construction.
공기 단축 및 공사비를 절감한다Reduced air and construction costs
레벨 및 선형조정을 위해 투입되던 시간을 단축할 수 있어 공기 및 공사비를 절감할 수 있다The time spent on level and linear adjustments can be shortened, reducing air and construction costs.
