Correction method for building on ground foundation

Abstract

The invention discloses a deflection correction method for a ground-based building, which includes 1. Drilling holes on the side opposite to the inclination direction of the building, the drilling holes include vertical scour holes and oblique drainage holes, and the vertical scour holes and oblique drainage holes The holes intersect at the bottom; 2. Insert the semicircular pipe retaining wall into the vertical flushing hole, and insert the circular pipe retaining wall into the oblique drainage hole; 3. Insert the stirring rod connected with the high-pressure water pump into the vertical flushing hole. Inject high-pressure water to wash the soil under the foundation of the building, soften it and partially form mud, and then extend the mixing head equipped with the spray head sideways towards the foundation soil, and then start the motor to rotate the mixing head and stir the soil 4. After the building is gradually corrected, use a pump to insert a water pump into the oblique drainage hole to drain the mud in the hole; 5. To the drainpipe Inject the soft soil curing agent in the state of grout to solidify the foundation soil; 6. Finally, pour cement slurry to seal the hole. The method can quickly correct the deviation of the foundation of the building, and form a more solid solidified soil.

Description

technical field [0001] The invention relates to a method for rectifying deviations of ground-based buildings. Background technique [0002] Traditional soil foundation correction generally uses manual or mechanical methods to hollow out one side of the soil, and the foundation remains horizontal. However, manual or mechanical hollowing out of the soil is inconvenient for construction, and the construction period is longer. More importantly, it often has no effect on large buildings. poor. Contents of the invention [0003] In view of the deficiencies in the background technology, the technical problem to be solved by the present invention is to provide a method for rectifying deviations of soil foundation buildings that is more convenient for construction, shortens the construction period, and can form better soil solidification effects. [0004] The present invention is accomplished by adopting the following technical solutions: a method for rectifying a building on a gr...
