Method for constructing earth anchor of retaining wall

Method for constructing earth anchor of retaining wall:

Problem to be solved: to provide a construction method of an earth anchor of a retaining wall capable of preventing the congestion of the type of the hole by forming the hole of the anchor hole and the formation of the fixing body from the ground portion to reduce the replacement time by reducing the replacement of the construction machine. Solution: the drilling rod 5 is started from a boring ring 7 installed at the position of a predetermined distance 37 from the retaining wall 35 on the excavation side 35 to control the rotation and the non rotation of the drilling rod 5 while the vibration is applied to the rod rod 5 or the tip bit Thus, the bent boring hole 9 is cut into the ground 1.The drilling rod 5 reaches the anchor placing position 11 of the retaining wall 3 at a predetermined angle, and then cuts the straight anchor hole 10 into the retaining wall 3 and the ground 1.
