An installation method of a sheet pipe using a guide pipe is provided to install a sheet pile to weathered rock, soft rock, hard rock and boulder stone layers by installing a sheet pile using a guide pipe and to improve construction quality by coupling a guide pipe and a sheet pile and keeping perpendicularity exactly. An installation method of a sheet pipe using a guide pipe comprises the steps of: perforating the ground, inserting a casing, inserting a guide pipe(100) into the casing primarily and drawing out the casing; re-inserting the casing to the ground in the proceeding direction of construction to make a minor arc of the casing in contact with a guide plate of the guide pipe; inserting a guide pipe into the casing secondarily and drawing out the casing again, and placing suspension grout(300) in the primarily inserted guide pipe; drawing out the primarily inserted guide pipe and inserting a sheet pipe(2), and coupling with the secondarily inserted guide pipe; and forming a retaining wall by installing many sheet piles which are coupled with each other through the above mentioned steps. |
