Title:
CONSTRUCTING METHOD FOR SELF-SUPPORTING LANDSLIDE PROTECTION WALL
Document Type and Number:
Japanese Patent JP2601140
Kind Code:
B2
Abstract:
PURPOSE: To hold strength and rigidity without using a working face by integrating a field-constructed pile with a soil-cement column-line landslide protection wall.
CONSTITUTION: A soil-cement column-line landslide protection wall 1 is constructed and a field-constructed pile 2 reinforced by an iron core cage 2" and eccentric anchors is constructed on the side of the ground to be drilled. Primary drilling is performed and an assisting material 3 in the form of a rectangular box and two assisting materials 4, 4 in the form of a trapezoidal box are packed in the gap between every field-constructed pile 2 and the soil-cement column-line landslide protection wall 1, and a filler is injection into the gap and the materials 3, 4 are fastened together by means of a bolt 5 and integrated with the filed-constructed pile 2. An H-steel wale 7 is extended along the soil-cement column-line landslide protection wall 1 between field-constructed piles 2, 2, and is fastened to the rectangular-box-shaped assisting material 3 by means of a bolt 6. Final drilling is performed and the rectangular-box- shaped assisting material 3, the trapezoidal assisting material 4 and the H-steel wale 7 are constructed in sequence according to the depth of drilling. After a skeleton is constructed, the H-steel wale 7 is removed.
