Summary:PROBLEM TO BE SOLVED: To provide a caisson immersion method that enables simple execution of high-quality work for a caisson, and a friction cut structure.SOLUTION: A caisson immersion method includes: a first step of excavating ground along an outer shape of a cutting edge 3 provided at a lower end of a caisson 1 and immersing the caisson 1; and a second step of excavating the ground G while friction-cutting an outer periphery of the cutting edge 3 and immersing the caisson 1. In the second step, a plurality of jigs 6 for friction-cutting are protruded outward from the lower end of the cutting edge 3.SELECTED DRAWING: Figure 2 【課題】ケーソンの高品質施工を簡易に行うことができるケーソンの沈設方法およびフリクションカット構造を提案する。【解決手段】ケーソン１の下端に設けられた刃口３の外形状に沿って地盤を掘削するとともにケーソン１を沈設する第一工程と、刃口３の外周囲をフリクションカットしつつ地盤Ｇを掘削するとともにケーソン１を沈設する第二工程とを備えるケーソンの沈設方法であって、第二工程では、刃口３の下端から外方向に向けて複数のフリクションカット用治具６を突出させる。【選択図】図２
