Before the same work as the installation of the tower body, a unified command and division of labor shall be carried out to monitor the ground anchor. The detailed inspection of all works shall be carried out to ensure that the machine will not be stopped in the middle of the position. Before placing the tower, a long steel wire rope shall be tied from the top of the tower to pull the inclined tower body with a crane or reaming mill until the tower body exceeds the center of gravity, then the winch can be started to slowly lower the tower body. When approaching to the ground, the speed shall be slowed down to minimize the vibration when the tower body is placed on the pile.
