SURFACE PRESSING ROCK-BOLTING METHOD |
摘要 |
PURPOSE: A surface pressing type rock-bolting method is provided to reduce construction time and costs by simultaneously reinforcing the ground of a rock slope and the surface of the rock slope. CONSTITUTION: A surface pressing type rock-bolting method is as follows. Multiple boreholes are formed on a rock slope. Each rock bolt, composed of a body part(210) and a rear head part(220), is inserted into each borehole. The rear head parts of the rock bolts are protruded to the outside the rock slope. Pressing plates(100) are inserted into the rear head parts of the rock bolts. A fixing nut(400) is coupled to the rear head part of each rock bolt to press the flat plate parts(110) of the pressing plates. |
