Abstract

본 발명은 기반시설구축 및 도시재개발 공사등으로 대규모 진행되고 있는 흙막이 공사나 터널축조시 지반의 붕괴를 방지하기 위해 지반을 적정간격으로 천공하고, 이에 철근을 삽입후 그라우팅하는 지반조강공법에 관계되는 것으로 지반을 천공과 동시에 스크류를 빼내면서 그루우팅을 동시에 실시하는 천공스크류의 비트에 선단확대용 비트를 설치하여 천공선단을 확대하므로서 선단부분의 지지력을 높이고 보다 완벽한 시공을 할 수 있도록 한 지하굴착용 선단 확대비트에 관한 발명이다.The present invention relates to a geotechnical process for ground-breaking and grouting, in which ground is inserted at an appropriate interval in order to prevent collapse of the ground during the earthworks construction or tunnel construction, It is possible to increase the bearing capacity of the end part by enlarging the perforation end by installing the bit for enlarging the end to the bit of the perforating screw which performs the grouting at the same time while drilling the ground and simultaneously removing the screw. This is an invention related to a tip enlargement bit.
