PURPOSE: A self-type earth retaining method for deep excavation is provided to prevent the deformation, damage, displacement, and so on caused by vibration due to an earthquake, water pressure, earth pressure applied to an earth retaining wall including a reinforcing support. CONSTITUTION: A self-type earth retaining method for deep excavation is composed of the steps of: arranging plural retaining walls(11) preventing the overturn of a diaphragm wall, inserting metal piles among the retaining walls; mixing and arranging the plural retaining walls reinforced by inserting the metal piles and retaining walls; and forming plural connection structures(14) connected to the both retaining walls in the ground. The retaining wall is formed by filling mortar grout in a drilled hole of the ground to prevent inflow of sand, earth, and underground water. |
