Description
Technical Field
The application relates to the technical field of high-tower high-pier construction, in particular to a cable tower operation platform template separation lifting system.
Background
At present, with the rapid development of traffic needs and the progressive progress of bridge technology, modern bridges are gradually developed towards large span, and due to structural needs and restrictions of landforms and landforms at bridge positions, bridge piers over hundreds of meters in bridge design and cable towers over hundreds of meters in bridge design are not rarely applied to cable-stayed bridges and suspension bridges, which puts higher requirements on construction technology. The cable tower column with the height is a difficult problem in modern bridge construction in terms of how to achieve high quality, safety and high efficiency of construction.
In the early construction of high pier and high tower, the slip form process and the turnover form process are applied more. The slip-form process has the characteristics of high construction progress, small occupied site, strong structural integrity, good comprehensive environmental and economic benefits and the like, but the pier column is poor in appearance quality during slip-form construction, high in construction organization difficulty and incapable of meeting the requirements of construction difficulty and construction quality at the present stage. In the turnover mold process, a pier body is used as a support main body, an upper layer template is supported on a lower layer template, and the pier body and the lower layer template are circularly and alternately lifted. The construction method has the characteristics of good entity and appearance quality and less investment, but the construction progress is slow, the whole wind resistance is poor, the safety factor is small, and the safety risk is high.
