Existing building foundation underpinning construction method
The invention belongs to the technical field of building construction, and particularly discloses an existing building foundation underpinning construction method which comprises the steps that a foundation is completely underpinned, a certain space is reserved at the top of an underpinning pile, micro-expansive concrete is used for pouring the reserved space, and a grouting pipe is pre-buried on the micro-expansive concrete foundation for grouting and filling. Cement-water glass slurry is sequentially injected into the underpinning pile top, and the problem of concrete gaps between an existing building foundation and the underpinning pile top is solved.
本发明属于建筑施工技术领域，具体公开一种既有建筑基础托换施工方法，对基础全部托换，在托换桩顶预留一定空间，使用微膨胀混凝土浇筑上述预留空间，且在微膨胀混凝土基础上预埋注浆管进行注浆填塞，将水泥‑水玻璃浆液依序注入托换桩顶，解决了既有建筑物基础和托换桩顶中间混凝土缝隙问题。
