PURPOSE:To work soil between walls and the walls as the sheathing of integral structure by tightly connecting the coffering wall at the excavation side (the inside) and the external coffering wall by a tie rod. CONSTITUTION:An underground continuous wall is formed doubly, and divided into the internal coffering wall 3 and the external coffering walls 4. The tightly connecting fittings of the tie rods 5 are mounted previously to the coffering walls 4. The coffering walls 3, 4 are completed, the ground is excavated up to predetermined depth, the tie rods 5 are executed, both coffering walls 3, 4 are tightly connected, and the next excavation is conducted. The tie rods 5 are executed toward the tightly connecting fittings 7 of the coffering walls 4 from the coffering wall 3, and the noses of the tie rods 5 are fixed to the tightly connecting fittings 7. With the tightly connecting fittings 7, one side is widened and the tie rods 5 are easily inserted in consideration of the error of the execution of the tie rods 5. |
