Connecting structure for combined type cylinder structure fan foundation and construction method
The invention discloses a connecting structure for a combined cylinder structure fan foundation and a construction method. The connecting structure comprises a cylinder based on a pile foundation structure and a bearing platform, chamfering structures are arranged on the inner side and the outer side of the cylinder wall of the cylinder at the joint of the cylinder and the bearing platform, the chamfering structures and the bearing platform are integrally poured and formed, and reinforcing meshes are arranged in the chamfering structures; and after construction of the cylinder formed by a pile foundation is completed and a fan foundation is excavated to the elevation of the bottom of the bearing platform, chamfering excavation is conducted in the direction of a cylindrical structure, steel bars are arranged, and finally the chamfering structures and bearing platform structural concrete are integrally poured. By arranging the chamfering structures, control over horizontal displacement of the top of the cylinder structure is enhanced, and the structural defect, caused by sudden change of structural rigidity, of the combined cylinder structure at the joint of the bearing platform and the cylindrical structure is effectively avoided and according to the connecting structure and the construction method, the problem that the cost is high due to the fact that the engineering quantity is increased due to other treatment measures is effectively solved.
本发明公开一种用于组合式圆筒结构风机基础的连接结构及施工方法，连接结构包括基于桩基结构的圆筒体和承台，圆筒体和承台连接处圆筒体筒壁的内侧和外侧设置倒角结构，倒角结构与承台一体化浇筑成型，倒角结构中布置钢筋网；在完成桩基形成的圆筒体施工完成并进行风机基础开挖至承台底部高程后，向筒型结构方向进行倒角开挖，并进行钢筋布置，最后将倒角结构与承台结构砼一体浇筑完成。本发明通过设置倒角结构对圆筒结构顶部的水平向位移加强控制，有效避免了组合式圆筒结构在承台和筒型结构连接处由于结构刚度突变引起的结构缺陷，本发明提供的连接结构及施工方法有效减少了其他处理措施引起工程量增加导致成本高的问题。
