CONSTRUCTION METHOD FOR UNDERGROUND STRUCTURE, SOIL CEMENT WALL, SOIL CEMENT WALL PILE, UNDERGROUND STRUCTURE, FOUNDATION STRUCTURE OF BUILDING, AND GROUND EXCAVATING EQUIPMENT

PROBLEM TO BE SOLVED: To provide a construction method for an inexpensively manufacturable underground structure with sufficient strength. SOLUTION: Soil cement 13 constitutes at least a part of the soil cement wall 10. The ground is partially drilled and agitated, a grouting liquid composed of a cement-based material is injected into drilled and agitated target soil, the target soil and the grouting liquid are mixed and agitated, and a mixture of the target soil and the grouting liquid is partially discharged. Thus, the soil cement which constitutes the underground structure is at least partially constructed in situ. COPYRIGHT: (C)2008,JPO&INPIT
