Abstract
The present application relates to a method for lifting a factory building floor in a weak soil layer geology, including: S1, measurement: measuring a settlement numerical value of a floor of a factory building and a depth of a weak soil layer; S2, determining grouting point locations: marking grouting point locations on a ground of the factory building, with equal distances between adjacent point locations; S3, inserting grouting pipes: inserting a plurality of grouting pipes at the grouting point locations, the grouting pipes passing through the weak soil layer and abutting against the bearing layer; and S4, grouting: forming support columns by grouting into the grouting pipes, while simultaneously withdrawing the grouting pipes from the weak soil layer.
Claims9
A method for lifting a factory building floor in a weak soil layer geology, comprising the following steps:
- S1, measuring a settlement numerical value of a floor of a factory building and a depth of a weak soil layer;
- S2, marking grouting point locations on a ground of the factory building, wherein all of the grouting point locations are arranged in a square array, with equal distance between adjacent grouting point locations of the grouting point locations in both horizontal and vertical directions;
- S3, inserting a plurality of grouting pipes at the grouting point locations, with the plurality of grouting pipes passing through the weak soil layer and abutting against a bearing layer;
- and
- S4, forming a support column by grouting into each of the plurality of grouting pipes, while simultaneously withdrawing the plurality of grouting pipes from the weak soil layer during the grouting.
