Method for hoisting beam section in cable-free area of half-through basket arch bridge
The invention relates to a method for hoisting a beam section in a cable-free area of a half-through basket arch bridge; the method comprises the following steps of: respectively mounting two cranes on two cables, respectively connecting the four cranes with four lifting lugs on the two sides of the beam section through lifting ropes, and hoisting the beam section into air; loosening the lifting ropes of the two obliquely-opposite cranes on the two cables, moving the other two obliquely-opposite cranes in the opposite directions, and enabling the beam section to rotate by 90 degrees in the air; and lowering the beam section to the ground, and then connecting the four cranes with the lifting ropes again to lift the rotated beam section to the installation position. Under the condition that a rotary lifting appliance is not adopted, beam section rotating and lifting can be achieved without adding any equipment, the equipment cost can be saved, and the construction process is safe and rapid.
本发明涉及一种中承式提篮拱桥无索区梁段吊装方法，两根缆索上分别安装两台吊机，4台吊机通过吊绳分别连接梁段两侧的4个吊耳，将梁段起吊到空中；松开两根缆索上斜对的两台吊机的吊绳，另两台斜对的吊机向相对方向移动，使梁段在空中转体90°；下放梁段到地面，然后4个吊机重新连接吊绳起吊转体后的梁段到安装位置。本发明在不采用旋转吊具的情况下，不增加任何设备即可实现梁段转体和吊装，可节约设备成本，且施工过程安全、快捷。
