Application manner of the steel pipe pole string earth retaining wall and is used for that yatsutoko

摘要

PURPOSE:To increase work efficiency by connecting a pliers to the upper part of a steel pipe pile placed in a pliers loading longitudinal hole, burying the steel pipe pile in a specific position until the head of the pliers is positioned in the vicinity of the surface of the earth, and separating the pliers from the steel pipe pile. CONSTITUTION:A pile 1 is hung in an longitudinal hole (H) with a diameter large than that of the steel pipe pile 1, and a pliers 10 is connected to the upper part of the pile 1. After that, the pile 1 connected to the pliers 10 is subsequently buried into the specific ground provided with a soil cement column to construct a steel pipe column strip retaining wall and, at the same time, the pile 1 is fixed to the inside of the soil cement column. The pliers 10 is separated from the pile 1 to draw it from the ground (G), and after carrying out the primary excavation l1 to the extent of the ceiling end position of the pile 1, the secondary excavation l2 of a specific side of a retaining wall (W) is carried out. Accordingly, fitting and release of the pliers 10 to/from the pile 1 is made easily, and work efficiency can be increased.
