Existing foundation beam type underpinning structure and construction method thereof
The invention discloses the technical field of building construction, and particularly relates to an existing foundation beam type underpinning structure and a construction method thereof.The existing foundation beam type underpinning structure comprises an existing foundation, an existing vertical structure is arranged on the upper portion of the existing foundation, the existing foundation beam type underpinning structure further comprises an underpinning beam, and the underpinning beam is arranged at the joint of the existing foundation and the existing vertical structure; the adjacent existing foundations are connected through the underpinning beams, the reinforcing piles are connected to the lower portions of the underpinning beams, loads transmitted to the existing foundations through the existing vertical structures of the existing structures are partially or completely transferred to the reinforcing piles through the underpinning beams, and meanwhile due to the fact that the adjacent existing foundations are connected through the underpinning beams, the existing structures and the existing vertical structures are connected through the underpinning beams. The integral rigidity and the differential deformation resistance between the existing foundations are enhanced, further, the settlement of the existing foundations is reduced by arranging underpinning beams and reinforcing piles, the earth excavation engineering amount and the disturbance to the existing foundations are reduced, and the reinforcing piles are formed to extrude the foundation soil and effectively reinforce the existing foundations.
本发明公开了建筑施工技术领域，特别是一种既有基础梁式托换结构及其施工方法，包括既有基础，所述既有基础的上部设置有既有竖向结构，还包括托换梁，所述托换梁设置在所述既有基础与所述既有竖向结构的连接处，相邻所述既有基础之间通过所述托换梁相连接，所述托换梁下连接有补强桩，通过托换梁将既有结构通过既有竖向结构传递至既有基础上的荷载部分或全部转移至补强桩上，同时由于托换梁将相邻的既有基础相连接，增强了既有基础之间的整体刚度和抵抗差异变形的能力，进一步地，通过设置托换梁和补强桩来减少既有基础沉降，减少土方开挖工程量及对既有地基基础的扰动，补强桩成桩挤压地基土又有效加固既有地基。
