Title:
LIFTING AND REINFORCING PROCESS FOR DUST-FREE FACTORY FLOOR
Document Type and Number:
WIPO Patent Application WO/2023/165563
Kind Code:
A1
Abstract:
Disclosed in the present invention is a lifting and reinforcing process for a dust-free factory floor, comprising: reinforcing a soft foundation and precisely lifting a settlement range. The present invention has the following beneficial effects: since the integral integrity of a factory is not destroyed, the possibility that external dust enters the factory can be avoided, and since a rubber bag is adopted for grouting, the use efficiency of a grouting slurry is improved, and the situation that the elevation of an upper terrace is affected due to inefficient diffusion of the grouting slurry in foundation soil is prevented. Although the process can increase the construction cost, compared with the sum of the cost of a conventional grouting process and the overall cost of later-period overall plant dust removal, the process is lower in cost and more remarkable in effect.
