System and construction method used for integral hoisting and rotation of steel tower
The invention discloses a system and a construction method used for integral hoisting and rotation of a steel tower, pertaining to the field of bridge construction. The system comprises at least one lifting device. A lifting rope of one lifting device is connected with a hoisting point of the steel tower. Each hoisting point is located on one side of the center of gravity of the steel tower. The system further comprises a floating crane used for traction of the steel tower. A lifting rope of the floating crane is fixed on the other side of the center of gravity of the steel tower. When the floating crane releases the lifting rope of the floating crane, the steel tower rotates around each hoisting point. By adoption of the method, the steel tower is horizontally placed and conveyed to the position to be lifted. After the steel tower is horizontally lifted to the position where the distance between the steel tower and the water level is greater than half of the height of the steel tower, the lifting rope of the floating crane is placed downwards such that the steel tower bypasses each hoisting point to rotate around the right-forward direction of the length of the floating crane to be vertical. The method can not only help to realization of installation of the large steel tower but also help to ensure quality of the steel tower.
