PURPOSE:To quickly, easily, and exactly form a basement by a method in which the ground area to be treated for solidification is embedded with excavated soil with a hardening agent and hardened, and then the ground area where a basement unit is to be buried is excavated. CONSTITUTION:The ground area 2 to be treated for solidification is excavated and then embedded with the excavated soil with a hardening agent, and after hardening the area 2, the ground area 1 where a basement unit is to be buried is excavated to a given depth to form a well 3 to be buried with the basement unit. A basement-forming unit 4 whose outside is provided with an upside- opened iron bar cage 5 is set in the well 3. The bottom of the iron bar cage 5 is buried in the bottom portion of the well 3, concrete is placed to form the earth floor of the basement, and then concrete is placed between the surrounding wall of the unit 4 and the surrounding of the well 3. |
