Permanent and temporary combined tower crane foundation and construction method thereof
The invention discloses a permanent and temporary combined tower crane foundation and a construction method thereof, a cantilever cast-in-place box girder is used as the tower crane foundation, the structural safety of the cantilever cast-in-place box girder under various working states of a tower crane is ensured through rigorous structural stress simulation checking calculation, and an original temporary pile foundation and a bearing platform tower crane foundation are optimized in a permanent and temporary combined mode. The mounting height of the tower crane is effectively reduced, the investment cost of temporary measures is reduced, and resource waste caused by secondary breaking of the pile foundation and the bearing platform is avoided. The problems that in the cantilever cast-in-place bridge construction process, a foundation structure used for installing the tower crane needs to be broken subsequently and cannot be reused, and the construction cost is high are solved.
本发明公开了一种永临结合塔吊基础及其施工方法，采用悬臂现浇箱梁作为塔吊基础，通过严谨的结构受力模拟验算保证悬臂现浇箱梁在塔吊各种工作状态下的结构安全性，以一种永临结合方式优化原有临时性桩基、承台塔吊基础，有效降低塔吊安装高度，减少临时措施投入成本，避免桩基、承台二次破除产生的资源浪费。本发明解决了悬臂现浇桥梁施工过程中的用于安装塔吊的基础结构后续需要破除，无法重复利用，施工成本高的问题。
