FOUNDATION CONSTRUCTION METHOD AND FOUNDATION CONSTRUCTION SYSTEM
PROBLEM TO BE SOLVED: To provide a foundation construction method capable of driving a long pile member efficiently at a high accuracy and low costs, even into a soft ground.SOLUTION: A foundation construction method is for constructing a foundation 1, with a guide member 10 provided with a tube part 12 and at least two pile members 20 inserted into the tube part 12 of the guide member 10, the tube part 12 having a central axis inclined from the vertical direction and extending without interfering with each other. The foundation construction method includes steps S1, S2 in which the guide member 10 is temporarily fixed on a ground surface, steps S3 to S7 in which the pile member 20 is inserted into the tube part 12 of the guide member 10 and at least a tip of the pile member 20 is driven into the ground, a step S8 for calculating the bearing capacity of the pile member 20 based on the amount of time needed for driving the pile member 20, and a step S9 for determining whether or not the position of the guide member 10 and the bearing capacity of the pile member 20 are within a prescribed tolerance.
【課題】軟弱地盤においても、長い杭部材を効率的かつ高精度で安価に打ち込むことができる基礎構築方法を提供すること。【解決手段】基礎構築方法は、筒部１２が設けられたガイド部材１０と、このガイド部材１０の筒部１２に挿通される少なくとも２本の杭部材２０と、を備え、筒部１２の中心軸は、鉛直方向に対して傾斜してかつ互いに干渉することなく延びる基礎１を構築する方法である。この基礎構築方法は、ガイド部材１０を地表面に仮固定するステップＳ１、Ｓ２と、ガイド部材１０の筒部１２に杭部材２０を差し込んで、杭部材２０の少なくとも先端部を地中に打ち込むステップＳ３〜Ｓ７と、杭部材２０の打ち込みにかかる時間に基づいて杭部材２０の支持力を算定するステップＳ８と、ガイド部材１０の位置および杭部材２０の支持力が所定の誤差の範囲内であるか否かを判定するステップＳ９と、を備える。【選択図】図９
