Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for lifting and reinforcing factory floors in dust-free environments increase the risk of dust ingress due to grouting holes and channels, leading to increased costs and inefficiencies in maintaining dust-free conditions.
Innovation Solution
A process involving precise drilling and grouting techniques, including designing drilling curves, guiding holes, and using a rubber bag for controlled grouting to lift and reinforce the floor without damaging the foundation, ensuring accurate horizontal lifting and minimizing dust entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional drilling grouting machine is used to drill holes and grout the ground, then the settlement can be corrected, but the factory floor will be damaged and dust-free conditions will be compromised
Solution Approach 1:
The patent divides the grouting process into two distinct stages: first reinforcing the soft foundation layer, then later lifting the factory floor. This segmentation allows each operation to be optimized independently, with the foundation reinforcement creating a stable base before the floor lifting operation, thereby avoiding the need for extensive grouting holes that would compromise dust-free conditions.
Solution Approach 2:
The patent performs preliminary reinforcement of the soft foundation layer before attempting to lift the factory floor. By pre-installing grouting channels and strengthening the foundation soil first, the subsequent floor lifting can be achieved with minimal disturbance to the factory interior and fewer grouting holes requiring repair.
2Strength
If grouting holes are drilled deep into the foundation soil to reach fissures and underground water, then foundation reinforcement is improved, but the risk of dust entering the factory through connected channels increases
Solution Approach 1:
The patent introduces a rubber bag as an intermediary device during the floor lifting process. The rubber bag is inflated with grouting slurry to provide controlled upward pressure, lifting the floor horizontally without requiring deep grouting holes that would penetrate into fissures and underground water channels, thus preventing dust communication pathways.
Solution Approach 2:
The patent utilizes hydraulic principles by injecting grouting slurry into the rubber bag to generate controlled pressure for lifting the factory floor. This hydraulic lifting mechanism achieves the desired floor elevation without requiring mechanical drilling deep into the foundation, thereby avoiding creation of dust pathways to underground water.
3Productivity
If multiple grouting holes are created to address large settlement areas, then lifting effectiveness is improved, but the complexity of repairing and sealing holes increases
Solution Approach 1:
The patent makes the grouting channels multi-functional by using them for both foundation reinforcement and subsequent floor lifting operations. The same channels that were installed during foundation reinforcement are reused for injecting grouting slurry to inflate the rubber bag and lift the floor, eliminating the need for separate repair and sealing operations for each hole.
Solution Approach 2:
The patent merges the foundation reinforcement operation with the floor lifting operation by using the same grouting infrastructure. The grouting channels installed for foundation reinforcement are also used for floor lifting, combining two separate processes into one integrated system that reduces the number of holes needing repair and simplifies the overall procedure.

AI summary
Disclosed in the present invention is a lifting and reinforcing process for a dust-free factory floor, including: reinforcing a soft foundation and precisely lifting a settlement range. Reinforcing a soft foundation includes: step 1: determining a depth of a soft soil layer in an inner settlement area of the factory, and designing a drilling curve; step 2: drilling guiding holes from the outer construction point of the factory; step 3: connecting and communicating grouting channels; and step 4: grouting. Lifting a settlement area includes: step 1: determining a depth range between the reinforced soft foundation and the floor, and designing the drilling curve; step 2: drilling the guiding holes; step 3: connecting and communicating the grouting channels; step 4: starting grouting; and step 5: stopping grouting.
