PURPOSE:To prevent deformation of a landslide protection wall, by a method wherein a steel rod is removably attached to a steel material in a manner to be inclined in the direction of depth and is erected in a ditch hole, and after a stabilizing solution, with which the ditch hole is filled, is cured, the steel rod is removed after it is stretched. CONSTITUTION:After a ditch hole 10 for building a landslide protection wall and a ditch hole 14 for inserting a prestless steel rod thereinto are excavated in succession, the ditch holes 10 and 14 are filled with a self-curing stabilizing solution 15. Thereafter, a prestless steel rod 18, inclined in the direction of depth within the ditch hole 10, is removably attached to a steel material 16 to erect the steeel rod in the ditch hole 10. Thereafter, after the stabilizing solution 15 is cured, the steel rod 18 is stretched with the aid of a jack 22 to introduce the prestless into a landslide protection wall. Further, after the inside of the landslide protection wall is excavated to build an underground structure 28, the steel rod 18 is unscrewed from a stationary member 26 for removal and recovery. |
