THE CREATION OF LOAD TEST SET FOR LARGE DIAMETER BATTERED STEEL PIPE PILE CONSTRUCTED ON THE COASTAL AREA

摘要

PURPOSE: Structure of a load test piece for confirming the support force of an inclined large diameter marine pile is provided to test a static axial load about the pile on the sea directly. CONSTITUTION: According to the structure of a load test piece for confirming the support force of an inclined marine pile(11) having a diameter of at least 800mm, an inner pile(12) is inserted within the large diameter pile. A tip end portion(121) and a head portion(122) of the inner pile are closed with a reinforcing plate, and a plurality of stabilizing beams(123) that a roller is attached at the end thereof are fixed to the outer wall of the inner pile in order to minimize a frictional force between the inner pile and the large diameter pile, prevent buckling thereof and maintain a direction of load in a direction of inclination. A hydraulic jack is installed to the head portion of the inner pile to apply a load. The large diameter pile is provided with a reactive member for the hydraulic jack to apply the load to the inner pile by using the hydraulic jack, thereby measuring a tip end support force of the inclined marine pile.
