High-rise building settling reinforcing and lifting correcting construction method

A high-rise building settling reinforcing and lifting correcting construction method, comprising:

• step 1, forming a curtain wall:
• drilling holes vertically downward around a foundation slab of a building to form multiple curtain wall holes at intervals;
• injecting slurry into the curtain wall holes, wherein slurry ranges of two adjacent curtain wall holes meshes and overlaps with each other;
• and forming a curtain wall, wherein the curtain wall encloses foundation soil under a range of the foundation slab of the building;
• step 2, forming a reinforcement body:
• providing multiple vertical reinforcement slurry injection holes in the foundation slab of the building, and injecting slurry in the reinforcement slurry injection holes to reinforce all soil close to the foundation slab to form the reinforcement body;
• and
• step 3, lifting slurry injection:
• drilling a hole downward to form a lifting hole, wherein the lifting hole penetrates from the ground to a certain depth below a bottom part of the reinforcement body, hole bottom of the lifting hole is higher than wall bottom located on the curtain wall;
• pressure-injecting slurry on the bottom part of the lifting hole, wherein, with continuous increase of the slurry in the curtain wall, injected slurry rapidly solidifies, the foundation soil in the curtain wall is continuously filled and compacted, and the foundation soil in the curtain wall form lifting force with increase of pressure and compactness such that the building is lifted gradually to a determined lift height.
