Pier foundation underpinning structure and construction method
The invention relates to a pier foundation underpinning structure and a construction method. The pier foundation underpinning structure comprises a foundation pit supporting body arranged on the sideface of a foundation pit dug in advance, underpinning piles symmetrically arranged in the foundation pit and located on the two sides of an original pier foundation, an underpinning beam fixedly connected with the original pier foundation, supporting pieces which are arranged at the top ends of the underpinning piles and used for supporting the underpinning beam, and a channel supporting main bodywhich is arranged in the foundation pit and fixedly connected with the bottom surface of the underpinning beam. The construction method comprises the following steps of constructing the foundation pit supporting body; pouring the underpinning piles and occlusive piles; pouring and molding the channel supporting main body; pouring the underpinning beam; carrying out jacking and pile cutting operations; arranging the supporting pieces on the underpinning piles; and backfilling building waste and soil into the foundation pit to form a backfill layer. The pier foundation underpinning structure belongs to the technical field of urban foundation engineering construction, and has the advantages that the stability of the pier foundation underpinning structure can be improved, the bearing performance of the underpinning structure is improved, and the whole construction process is more energy-saving and environment-friendly.
本申请涉及一种桥墩基础托换结构及施工方法，其中，桥墩基础托换结构包括设在预先挖设好的基坑侧面的基坑支护主体、对称设在基坑内位于原桥墩基础两侧的托换桩、与原桥墩基础固定连接的托换梁、设在托换桩顶端用于支撑所述托换梁的支撑件和设在基坑内且与托换梁的底面固定连接的通道支护主体。施工方法包括如下步骤：基坑支护主体的施工；浇筑托换桩和咬合桩；将通道支护主体浇筑成型；浇筑托换梁；进行顶升和截桩操作；在托换桩上设置支撑件；将建筑废料和土回填至基坑中形成回填层。本申请属于城市基础工程建设的技术领域，其具有能提高桥墩基础托换结构的稳定性、改善托换结构的承载性能和使整个施工过程更节能环保的优点。
