Special-shaped foundation structure of tower crane and construction method of special-shaped foundation structure
The invention discloses a special-shaped foundation structure of a tower crane and a construction method of the special-shaped foundation structure. Existing engineering pile foundation bearing platforms are utilized, and the pile foundation bearing platforms on the two opposite sides of the tower crane installation position are communicated to form a second-stage bearing platform foundation for tower crane installation. And the force transmission assembly is arranged in the second-stage bearing platform foundation formed after penetration, so that the tower crane is stressed uniformly during rotating operation, the force transmission path is clear, and normal construction operation is ensured. The force transmission assembly comprises a straight hidden beam, an inclined hidden beam and a connecting hidden beam, the hidden beam is additionally arranged in the second-stage bearing platform, the first-stage bearing platform and the second-stage bearing platform are connected into a whole, the bearing platform is firmer, the path for transmitting loads on the upper portions of the bearing platform and the pile foundation to the pile foundation is definite, the bearing platform and the pile foundation are evenly stressed, and the bearing platform and the pile foundation are not damaged. The problems of cracking of the bearing platform and overlarge stress of local pile foundations are avoided, and the safety of the tower crane is ensured. The problems that when a tower crane foundation is built in the later period of a building construction site, a pipe pile machine is introduced in a traditional method to construct newly-added pipe piles and bearing platforms, the cost is high, and the construction period is affected are solved.
本发明公开了一种塔吊异形基础结构及其施工方法，利用现有的工程桩桩基承台并将塔吊安装位置的相对两侧的桩基承台贯通形成二期承台基础以用于塔吊安装。贯通后形成的二期承台基础内设置传力组件，使得塔吊在旋转作业时受力均匀，传力路径明确，保证正常的施工作业。传力组件包括直暗梁、斜暗梁和联结暗梁构成，在二期承台内加上暗梁，使一期承台、二期承台联结为一个整体，使得承台更加牢固，承台及桩基的上部荷载传导至桩基的路径明确，承台及桩基受力均匀，避免承台开裂和局部桩基受力过大的问题，保证了塔吊安全。本发明解决了在建筑施工现场后期建设塔吊基础，采用传统方法引进管桩桩机施工新增管桩和承台，成本较高，且影响工期的问题。
