PURPOSE: A construction method of a large diameter bearing pile on a rock layer is provided to improve frictional force and support force of a bearing pile and reduce construction times and construction costs. CONSTITUTION: A construction method of a large diameter bearing pile on a rock layer comprises following steps. A hole(2a) is formed on a soft ground(2) to reach to a rock layer. A hole is formed on the rock layer at fixed depth so that a rock post(4) may be formed at the center of the rock layer. A reinforcing bar(5) is placed at the edge of a hole punched in the soft ground and the rock layer. Concrete is poured on the hole so that a bearing pile(1) may be formed. |
