Construction method for reinforcement and synchronous deviation rectification of existing building foundation
The invention relates to an existing building foundation reinforcing structure and a synchronous deviation rectifying method, a wall clamping beam and a wall penetrating beam are arranged on an existing foundation to enhance the overall rigidity of the existing building, the wall clamping beam is used as a counter-force supporting system to construct a foundation reinforcing pile in a reserved pile hole, and the bearing capacity of the foundation is improved; a reserved pile foundation reaction frame is used as a limiting device, inclined drilling is carried out, foundation soil is excavated for deviation rectification, after deviation rectification is completed, all pile sealing is completed, foundation connection reinforcing plates are poured, the foundation bottom area is increased under the condition that strip-shaped foundations are connected, and finally, voids below the foundations are filled in a micro-disturbance grouting mode, and re-inclination is prevented. The method has the advantages that reinforcement and deviation rectification of the existing building foundation are synchronously achieved, the base area of the original foundation is increased, the bearing capacity of the foundation is improved, the long-term use requirement of a repaired building is met, building deviation rectification is achieved on the premise of limiting safety, and better deviation rectification safety, construction convenience and social economy are achieved.
本发明涉及一种既有建筑基础加固结构并同步纠偏的方法，在既有基础上布设夹墙梁与穿墙梁增强既有建筑物的整体刚度，利用夹墙梁作为反力支撑体系在预留桩孔内施工基础加固桩，提高基础的承载能力，预留桩基反力架作为限位装置，斜向钻孔掏挖地基土进行纠偏，纠偏完成后完成全部封桩，浇筑基础连接加固板，在实现连接条形基础的情况下增加基础底面积，最终以微扰动注浆的方式填补基础下脱空并预防复倾。本发明的优点是：同步实现既有建筑基础加固与纠偏，增加原基础的基底面积并提高基础承载力，满足修复建筑的长期使用要求，并在限位安全的前提下实现建筑纠偏，具有更好的纠偏安全性、施工便利性以及社会经济性。
