Soft soil area tower crane foundation construction supporting structure and construction method thereof
The invention provides a soft soil area tower crane foundation construction supporting structure and a construction method thereof. The supporting structure is located under a top plate of a basement, and comprises a supporting open caisson. The supporting open caisson comprises open caisson side retaining walls, well top ring beams, well bottom ring beams and open caisson structural corner columns, wherein the open caisson side retaining walls are formed on the periphery of a tower crane basic earthwork in an enclosing mode, the well top ring beams are sequentially connected with the tops of the walls, and the well bottom ring beams are sequentially connected with the bottoms of the walls. The size of the supporting open caisson adapts to that of a tower crane foundation. The structural corner columns are located at corners of every two adjacent open caisson side retaining walls. The top ends of the structural corner columns are connected with the bottoms of the well top ring beams, the bottom ends of the structural corner columns are connected with the tops of the well bottom ring beams, the upper portion of the section of each well bottom ring beam is wide, the lower portion of the section of each well bottom ring beam is narrow, and the inner side walls of the well bottom ring beams are settlement edges of the supporting open caisson. Workloads are reduced while the construction progress can be guaranteed, cost is reduced, and the problem that a crane tower is inserted in advance and is difficult to install is solved.
