Deviation rectifying method for building

Abstract

The invention relates to the technical field of building construction, in particular to a deviation rectifying method for a building. The method includes the steps: a, drilling pile pressing holes in the indoor environment of the building and positioning the drilling pile pressing holes on a foundation of the building; b, selecting at least two pile pressing holes with less settlement according to uneven settlement conditions of the building; c, drawing out soil in the selected pile pressing holes, inflating formed soil drawing-out holes, forming negative excess pore water pressure in soil bodies on the peripheries of the soil drawing-out holes and then draining water in the soil drawing-out holes; and d, pressing anchor rod piles into the pile pressing holes and sealing the piles. The deviation rectifying method has the advantages that after practice examination, the soil is drawn out of the pile pressing holes to rectify deviation, the building uniformly deforms during back inclination, the deviation rectifying effect is fine, and deviation rectifying design requirements are met.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a building deviation correction method. Background technique [0002] Conventional building rectification design and construction usually adopts outdoor excavation and forced settlement, supplemented by indoor stacking as appropriate. The traditional method of excavating soil outdoors is to disturb the underlying soil under the foundation by continuously excavating soil, and then realize forced deviation correction. However, there are many deficiencies in the practical application of the outdoor soil excavation construction technology: [0003] Using the traditional soil excavation method, the settlement rate of the building is small, and after the deviation is corrected, it is easy to cause a soil hole in the soil under the foundation or the closure effect of the soil is poor; at the same time, the scale of the outdoor excavation is too large, causing the reverse ...

Problems solved by technology

[0003] Using the traditional soil excavation method, the settlement rate of the building is small, and after the deviation is corrected, it is easy to cause a soil hole in the soil under the foundation or the closure effect of the soil is poor; at the same time, the scale of the outdoor excavation is too large, causing the reverse tilt during use after the deviation is corrected Problems; and for buildings with deep foundations, outdoor soil excavation is often due to the excessive disturbance of the soil in the shallow part of the foundation by the excavation holes, which causes the building to sink in a way of jumping and sinking, causing secondary deformation and damage to the structure Many, and after the correction and reset, the reinforcement of the soil at the bottom of the foundation is also difficult to deal with
