Suction type barrel-shaped foundation structure and construction method thereof
The invention discloses a suction type barrel-shaped foundation structure and a construction method thereof. The foundation structure comprises at least three barrel-shaped foundation structures and a jacket structure, the barrel-shaped foundation is arranged in a triangular or rectangular shape and is connected with the jacket structure through grouting; supporting rods are arranged between the adjacent cylindrical foundations, the supporting rods are connected through steel pipes, and the formed limiting steel frame is of a permanent structure or a temporary detachable structure. The construction method specifically comprises the steps that firstly, the barrel type foundation structure is constructed, the foundation is evenly injected to the designed elevation through a suction pump, the construction levelness is well controlled, and grouting of common-strength slurry is completed; hoisting the jacket structure to enable the grouting connection section steel pipe of the structure to be inserted into the steel pipe at the upper part of the cylindrical foundation structure; and finally, grouting connection construction is conducted, and the flange face levelness of the jacket structure is measured again. The invention relates to a suction type barrel-shaped foundation structure and a construction method thereof. The suction type barrel-shaped foundation structure and the construction method thereof are particularly suitable for high-capacity fan foundations in complex soil layers and deepwater sea areas.
本发明公开了一种吸力式筒型基础结构及其施工方法，其基础结构包括至少三个筒型基础结构和一个导管架结构；筒型基础呈三角形或者长方形布置，且与导管架结构之间采用灌浆连接；相邻的筒型基础之间设有撑杆，撑杆之间使用钢管相互连接，组成的限位钢架为永久结构或临时可拆卸结构；其施工方法具体为：先施工筒型基础结构，利用吸力泵均匀使基础贯入到设计标高，并控制好施工水平度，完成普通强度浆体的灌浆；再起吊导管架结构，使结构的灌浆连接段钢管插入到筒型基础结构上部的钢管内；最后进行灌浆连接施工，复测导管架结构的法兰面水平度。本发明中涉及吸力式筒型基础结构及其施工方法尤其适应于复杂土层，深水海域的大容量风机基础。
