FOUNDATION CONSTRUCTION METHOD AND FOUNDATION CONSTRUCTION SYSTEM
PROBLEM TO BE SOLVED: To provide a foundation construction method that can hammer in a long pile member effectively, with high accuracy and with low cost even in a soft ground.SOLUTION: There is provided a foundation construction method, including a guide member having cylinder parts and at least two pile members inserted to the cylinder parts of the guide member, in which the central axes of the cylinder parts extend without interfering with each other in a manner each inclining to the vertical direction. The foundation construction method includes: steps S1 and S2 of temporarily fixing the guide member to the ground surface; steps S3 to S7 of inserting pile members to the cylinder parts of the guide member, and hammering in at least a tip of the pile members to the underground; a step S8 of calculating, based on a time needed for hammering in of the pile members, bearing power of the pile members; and a step S9 of determining whether or not a position of the guide member and the bearing power of the pile members is within a predetermined margin of error.SELECTED DRAWING: Figure 9
【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。【解決手段】基礎構築方法は、筒部が設けられたガイド部材と、このガイド部材の筒部に挿通される少なくとも２本の杭部材と、を備え、筒部の中心軸は、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を構築する方法である。この基礎構築方法は、ガイド部材を地表面に仮固定するステップＳ１、Ｓ２と、ガイド部材の筒部に杭部材を差し込んで、杭部材の少なくとも先端部を地中に打ち込むステップＳ３〜Ｓ７と、杭部材の打ち込みにかかる時間に基づいて杭部材の支持力を算定するステップＳ８と、ガイド部材の位置および杭部材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
