STEEL PIPE SOIL CEMENT PILE AND ITS INSTALLATION METHOD AND DEVICE |
摘要 |
PROBLEM TO BE SOLVED: To provide a steel pipe soil cement pile for achieving economical installation and less drilled soil by eliminating the waste of a solidifying material and producing an increase in bearing power of the pile by increasing adhesion between a steel pipe and a soil cement even when using a normal steel pipe with no protrusion on the surface, and its installation method and device. SOLUTION: The steel pipe soil cement pile comprises a soil cement column 1 formed of the drilled soil and the solidifying material and the steel pipe 2 to be installed in the soil cement column 1. Soil cements 1a, 1b are filled outside and inside the steel pipe 2 and a soil cement 1c being richer in mixture than the soil cements 1a, 1b is filled on the outside surface of the steel pipe 2.
