The invention relates to a suspension cable hoisting structure and hoisting method for prefabricated parts in a steep valley terrain. The suspension cable hoisting structure comprises two sets of anchoring devices positioned at the two ends of a steep valley correspondingly, two guide suspension cables, a walking crown block, a driving device, a lifting device, a hoisting tool and a rotating device, wherein the walking crown block is installed through the anchoring devices and the suspension cables, the driving device drives the walking crown block to move along the guide suspension cables, the prefabricated parts are hoisted through the lifting device and the hoisting tool, the prefabricated parts are rotated to the corresponding installation station positions through the rotating device,and the hoisting process of the prefabricated parts can be completed easily, conveniently and rapidly. According to the suspension cable hoisting structure and hoisting method, the prefabricated parts such as prefabricated beams and aqueduct can be hoisted in the steep valley terrain, and the problem that the prefabricated parts cannot be transported to a to-be-installed station or are difficultto transport to the to-be-installed station under the condition that the construction site is limited in the steep valley terrain is effectively solved.
Description
technical field [0001] The invention relates to the technical field of bridge construction, in particular to a suspension cable hoisting structure and hoisting method for prefabricated components in steep valley terrain. Background technique [0002] At present, during the construction of bridges and water bridges, it is generally necessary to carry out piling construction first, then carry out the construction of columns and cover beams, and then install prefabricated components such as prefabricated beams and aqueducts; if the construction area is located in a steep valley terrain, the prefabricated beams The hoisting of prefabricated components such as aqueducts and aqueducts is difficult, and the construction period is often very long, which greatly increases the economic cost and time cost of bridge construction. [0003] Therefore, it is necessary to provide a suspension cable hoisting structure and hoisting method for prefabricated components in steep valley terrain. ...
