DIFFERENTIAL SETTLEMENT CONTROLLING METHOD OF FOUNDATION

摘要

PURPOSE:To reduce differential settlement by combining a settlement controlling pile having the spring mechanism expanding in the vertical direction in a pile head section with the foundation structural body, and moving part of weight to the settlement controlling pipe with the settlement of the structure. CONSTITUTION:A settlement controlling pile 3 having the spring mechanism expanding in the vertical direction in a pile head section is combined with the footing foundation 1 forming the foundation structural body to bear a structure to place. Weight of the structure is at the beginning assigned to the footing foundation 1 only, a load moving to the controlling pile 3 is increased with the settlement of the structure, and the load that the foundation 1 bears is reduced. According to the constitution, differential settlement can be prevented at a low cost.
