PILE ASSEMBLY FOR BIDIRECTIONAL LOAD TEST IN ASSISTING PILE CONSTRUCTION CONDITION AND BIDIRECTIONAL LOAD TEST METHOD USING SAME

摘要

Disclosed is a pile assembly. The pile assembly includes: a bidirectional load test device including a bidirectional load test cell unit; a pile-shaped main pile placed on the bidirectional load test cell unit, and having a hollow inside; an assisting pile placed on the main pile, and including a placement plate with a plurality of upper placement holes in the upper part of a pipe-shaped body; and an anchor structure including a plurality of lower anchor settlers fixed inside the main pile in response to each of the upper placement holes, and a plurality of anchor steel wires having the lower part fixed to each of the lower anchor settlers and having the upper part placed in each of the upper placement holes to be fixed with limited downward movement. The anchor steel wires are placed in the upper placement holes in a tense state in which tensile force is applied thereto to connect the assisting pile and the main pile, and the anchor structure enables the anchor steel wires to be separated from the lower anchor settlers in a released state in which the tensile force is released.;COPYRIGHT KIPO 2019
