PURPOSE: To enhance the safety of works by eliminating the need for wire passing-round work by a method wherein hanging wires are respectively attached at one end inside the base and both ends outside the base of a structure.

CONSTITUTION: Hanging wires 21, 22 and 23 are respectively attached at one end 11 inside the base 10 and both ends 12 and 13 outside the base 10 of a structure 1. Firstly, the hanging wires 21 and 23 are connected to a hoisting equipment such as crane or the like. Secondly, the wires 21 and 23 are pulled up by the equipment in order to lift up the structure 1. Thirdly, the hanging wire 21 attached at the one end 11 inside the base 10 is detached from the hoisting equipment. As a result, the structure 1 is rocked to be turned round with center at the other end 13 outside the base 10. At this time, the hanging wire 22 hangs from the one end 12 outside the base 10 down onto the ground. Fourthly, the hanging wire 22 attached at the one end 12 outside the base 10 is pulled instead of the hanging wire 21 in order to lift the one end side of the structure 1. When the structure 1 is brought to be horizontal under the state turned upsidedown, the hanging wires 22 and 23 are lowered, resulting in laying the structure 1 horizontally on the ground in order to complete the turning over of the structure 1.
