METHOD FOR CONSTRUCTING CONTINUOUS UNDERGROUND WALL AND STEEL PIPE PILE

摘要

A method for constructing a continuous underground wall includes: a steel pipe installation step of continuously alternately installing first steel pipes and second steel pipes in a construction direction; an excavation step of excavating a content in each of the first steel pipes and the second steel pipes; a first solidification material-filling step of pulling out the first steel pipe while the first steel pipe is being filled with concrete and after the first steel pipe has been filled with concrete; and a second solidification material-filling step of pulling out the second steel pipe while first piles are being disturbed using claws protruding to the outside of the second steel pipe while the second steel pipe is being filled with concrete or after the second steel pipe has been filled with concrete. Both sides of a second pile are joined to the first piles using replenishing concrete while the first pile is being disturbed using the claws.
