Title:
CONSTRUCTION METHOD OF EARTH ANCHOR OF EARTH RETAINING WALL
Document Type and Number:
Japanese Patent JP2019183441
Kind Code:
A
Abstract:
To provide a construction method of an earth anchor of an earth retaining wall capable of reduction of a construction period through preventing congestion of various construction processes and reducing replacement of construction machines by carrying out drilling anchor holes and forming anchorage bodies from a ground station.SOLUTION: Curved borehole 9 is drilled in the ground 1 by starting a drilling rod 5 from a boring machine 7 installed at a position separated with a predetermined distance 37 on the excavation side 35 from an earth retaining wall 3 constructed on the ground 1 by controlling rotation and non-rotation of the drilling rod 5 while applying vibration on the drilling rod 5 or impacting a tip bid 13. A linear anchor hole 10 is drilled in the earth retaining wall 3 and the ground 1 after the drilling rod 5 reach an anchor installation position 11 of the earth retaining wall 3 in a predetermined angle. Then, tension members are anchored on anchoring members arranged on a surface exposed through excavating an inner side of the earth retaining wall 3 after removing the drilling rod 5 while forming an anchoring body by inserting tension members in the anchor hole 10.SELECTED DRAWING: Figure 1
