Abstract
A wall straightening apparatus provides multiple independently controllable jacking members pressing outward on diagonal braces to push those braces against the wall to move the wall into a vertical alignment. Feedback control of the jacking members provides coordinated straightening of large wall sections with lessened cracking and distortion.
Claims17
A method for straightening a wall which extends below the ground comprising the steps of:
- placing a set of upright braces against an inner surface of the wall;
- affixing a corresponding set of jacking members against a floor spaced from the inner surface of the wall;
- attaching a diagonal brace between the jacking members and the upright braces so that extension of the jacking members pushes outward on upright braces against the inner surface of the wall;
- and
- automatically sensing a position of the upright braces to independently control the jacking members;
- wherein the jacking members are hydraulic cylinders controlled by hydraulic valves
- wherein the automatic sensing of the position of the upright braces is accomplished by a linkage between an upright brace and a hydraulic valve associated with a hydraulic cylinder acting on the upright brace.
