세미실드 공법의 활재 주입장치{An antiadditive pouring device of semishield method}An antiadditive pouring device of semishield method

본 고안은 세미실드 공법의 활재 주입장치에 관한 것으로, 더욱 상세하게는 상ㆍ하수도 또는 전력구 및 통신구와 같은 주요한 도시기반 시설을 지하에 매설하기 위해 내주벽에 관체의 설치와동시에 지하터널을 구축하는 세미실드 기계의 추진력을 원활하게 하여 이에 추진되는 관체의 마찰력을 최소화함으로서 작업효율을 향상할 수 있는 세미실드 공법의 활재 주입장치에 관한 것이다.The present invention relates to a skid injection system of the semi-shield method, and more specifically, to build underground tunnels at the same time as the installation of pipes on the inner circumference to bury major urban infrastructure such as water, sewage or electric power and communication. It relates to a semi-shielding injection method of the semi-shield method to smooth the propulsion force of the semi-shielding machine to minimize the frictional force of the tubular body to improve the working efficiency.

일반적으로 세미실드 공법으로 장거리의 지하터널을 구축할 때 터널 내벽이 붕괴되는 것을 방지하기 위해 세미실드 기계로 타설되는 터널의 내주벽에 다수개의 조립 관체를 추진시켜 설치하게 되는 데, 종래에는 터널의 내부에 다수개의 조립관체를 유공압으로 추진시켜 설치함에 따라 토사 또는 암반으로 관통되는 장거리의 터널내부에 발생되는 마찰압력으로 조립관체의 추진을 하는 데 매우 큰 유공압을 필요로 하는 문제점이 있었고, 이에 조립관체의 주연으로 다수의 구멍을 뚫고 액상활재를 투입하여 조립관체의 추진을 용이하게 할 수 있었으나 이는 일일이 수작업으로 구멍에 액상활재를 주입해야 함에 따라 활재의 주입량과 주입압이 일정하지 않고 작업이 불편하여 작업효율이 저하되는 문제점이 있었을 뿐 아니라 경제적으로 인건비의 상승시키는 등의 여러가지 폐단이 있었다.In general, when constructing a long-distance underground tunnel with a semi-shield method, in order to prevent the inner wall of the tunnel from collapsing, a plurality of assembly pipes are pushed and installed on the inner circumferential wall of the tunnel which is placed by a semi-shielding machine. As a large number of assembly pipes are propelled into the pneumatic pressure therein, there is a problem that a very large pneumatic pressure is required to propel the assembly pipes with the frictional pressure generated in the long-distance tunnel penetrating into the soil or rock. The periphery of the tube was used to facilitate the promotion of the assembly by drilling a plurality of holes and injecting the liquid active material. However, since the liquid active material must be injected into the hole manually by hand, the injection amount and injection pressure of the lubricant are not constant and the work is inconvenient. Not only did the work efficiency deteriorate, but the labor cost economically There were many such evils that.

본 고안의 목적은 종래의 이와같은 문제점을 해소 하고자 한 데 있는 것으로 세미실드의 후단에 추진 잭으로 추진설치되는 조립관체에 관접되게 원통관을 착설하여 이의 외주연에 요입설치된 분사노즐로 윤활성을 가진 고점도의 액상활재를 굴진되는 지하터널의 내주벽으로 도포함으로서 조립관체의 추진력을 향상시킬 수 있는 세미실드 공법의 활재 주입장치를 제공코자 한 데 있는 것이다.The purpose of the present invention is to solve such a problem in the related art. The cylindrical tube is installed to be in contact with the assembly pipe propelled by the propulsion jack at the rear end of the semi-shield and has a lubricity with the injection nozzle installed at the periphery thereof. The purpose of the present invention is to provide a semi-shielded sliding material injection device that can improve the propulsion of the assembly pipe by coating the high viscosity liquid active material into the inner circumferential wall of the underground tunnel to be excavated.
