Zusammenfassung:PURPOSE:To facilitate building of a landslide protection wall at a densly built-up area, by method wherein a hole is bored in an existing underground outer wall, and after a ground right thereunder is excavated down to a given depth, a pile for landslide protection is driven in the hole. CONSTITUTION:After a hole is vertically bored in and through an existing underground outer wall 10, a series of boring is effected down to a depth matching the construction depth of an underground structure 13 for a newly constructed building. After an H-steel 12 is driven into a hole 11, a pit excavation work is conducted as the existing underground outer wall 10 part is removed with the aid of the H-steel.
