PURPOSE:To exactly measure the peripheral surface bearing capacity of a buried pile by a method in which a custom-made pile having an expanded resin spacer on its lower end is penetrated into a test hole drilled in the ground, a solidifying liquid is injected between the pile and the hole wall and hardened, and a testing load is applied to the pile. CONSTITUTION:A test hole A is drilled in the ground, and a custom-made pile 3 tipped with a specer 2 made of a synthetic expanded resin is penetrated into the hole A. A solidifying liquid 4 is injected between the periphery of the pile 3 and the wall of the hole A and hardened. A testing load W is then applied to the upper end of the pile 3, and while lowering the pile 3, the surface friction force of the buried pile is measured. The surface bearing capacity of the buried pile can thus be measured exactly. |
