Underpinning pile construction method using building body pile foundation
The invention discloses an underpinning pile construction method utilizing a building body pile foundation. The building body is provided with a building bottom plate (3), and the top of the building body pile foundation (1) is connected with the building bottom plate; the underpinning pile construction method comprises the steps that pile breaking operation is conducted on a body pile foundation of a building, and the body pile foundation is separated from a building bottom plate; based on a body pile foundation, an underpinning jacking device (6) is adopted for lifting a building bottom plate, and a building body is lifted to the pile foundation underpinning height; the building bottom plate and the top of the body pile foundation are connected and fixed together; and carrying out structure original appearance recovery construction operation on the joint of the building bottom plate and the top of the body pile foundation. According to the underpinning pile construction method, when underpinning pile construction is conducted on the building body, the body pile foundation of the building body is fully utilized to be transformed into the underpinning pile, the engineering construction cost can be greatly reduced, the construction procedure is simplified, the construction difficulty is reduced, and therefore the construction efficiency is greatly improved.
本发明公开了一种利用建筑体本体桩基的托换桩施工方法。建筑体具有建筑底板(3)，建筑体本体桩基(1)的顶部与建筑底板连结在一起；托换桩施工方法包括：对建筑体的本体桩基实施断桩操作，将本体桩基与建筑底板脱离开；基于本体桩基，采用托换顶升装置(6)来提升建筑底板，将建筑体提升至桩基托换高度；将建筑底板与本体桩基的顶部连结固定在一起；对建筑底板与本体桩基顶部连结处实施结构原貌恢复施工作业。在本发明托换桩施工方法中，在对建筑体进行托换桩施工时，充分利用建筑体的本体桩基来改造作为托换桩，不但能够大幅降低工程建设成本，而且简化了施工程序，降低了施工难度，从而使得施工效率大幅提升。
