AI Technical Summary

Technical Problem

Existing technologies for repairing subsided concrete floors suffer from problems such as long construction cycles, high costs, poor controllability, and insufficient environmental protection. In particular, traditional demolition and reconstruction methods result in construction waste and uneven repair.

Method used

Hydraulic jacks and reaction frame devices are used. The hydraulic jacks push the lifting column to raise the subsided concrete floor. A level and adjusting feet are used to ensure the uniformity and accuracy of the lifting process. The lifting height is monitored by a control unit, and the adjustable feet can adapt to differences in ground height.

Benefits of technology

It achieves efficient and environmentally friendly lifting of subsided concrete floors, ensuring accuracy and uniformity in the construction process, reducing construction waste, shortening the construction cycle, and lowering costs.

Abstract

The utility model relates to the technical field of building construction equipment, in particular to a sinking concrete terrace jacking reaction frame device which comprises a hydraulic jack, a hydraulic pump station communicated with the hydraulic jack and a control unit used for controlling the hydraulic pump station. The end, away from the hydraulic jack, of the counter-force frame is in bolted connection with the to-be-repaired concrete terrace, the output end of the hydraulic jack is connected with a jacking stand column, the to-be-repaired concrete terrace is provided with a through hole for the jacking stand column to penetrate through, and the output end of the hydraulic jack faces the through hole. And when the hydraulic jacks push the jacking stand columns to penetrate through the through holes to continue to move, the concrete terrace to be repaired is lifted under the reverse thrust of the jacking stand columns, displacement sensors on the hydraulic jacks are electrically connected with the control unit, and the top repairing efficiency of the sunken concrete terrace can be improved.
