Steel pipe pile with H-beam and heat-driven underground continuous wall method using it

摘要

The present invention relates to a steel pipe pile using H-shaped steel, and a main thermal type underground continuous wall method using the same.;According to the present invention, both ends of the flange 9 of the H-shaped section 7 are welded to one side of the outer circumferential surface of the steel pipe pile 2 which is lined or embedded in the underground or underwater ground, And both ends of a flange (10) of an H-shaped steel (8) having a relatively small size are welded to be sandwiched between flanges (9) of an H-shaped steel (7) of an adjacent steel pipe A steel pipe file with this attached is provided.;In addition, the steel pipe pile 2 is embedded or type in the ground or underwater so that the H-shaped steel pipe 8 is sandwiched between the H-shaped steel pipe 7 and H-shaped steel pipes 7, A submerged continuous wall method is provided in which a rubber tube 16 is inserted into the space portion 15 to be filled with air or a filler 17 such as mortar or soil cement or water expansive agent is injected into the rubber tube 16 .
