Abstract:
A grout injecting/structure anchoring system for solidifying a structure by supporting it from bedrock and filling any subterranean voids which would otherwise cause structural instability, the system comprising, in combination:a structure susceptible to instability due to any subterranean voids, the structure having a foundation positionable on soil over bedrock; a hollow cylindrical supportive tube having a first inner diameter and being adapted to be inserted into soil adjacent to the foundation of the structure and through any subterranean void, the supportive tube having a closed bottom end being provided with a cap and firmly abutted to bedrock there beneath, the supportive tube having an open top end being positioned adjacent to the foundation of the structure, the supportive tube further having a linear body between the top end and the bottom end with a plurality of circular apertures equally spaced circumferentially and axially along the entire length of the linear body; an L-shaped support bracket adapted to be securely placed under the foundation of the structure with a weight bearing horizontal portion adapted to support the foundation and an aligning vertical portion, the aligning vertical portion having a pair of apertures with horizontal bolts adapted to couple the support bracket to the foundation, the support bracket having adjusting elements including vertically oriented internally threaded sleeves and a vertically oriented unthreaded sleeve there between with a cross brace having a central section and laterally spaced on unthreaded apertures and laterally spaced vertical bolts, each bolt having an upper nut, each bolt having a lower extent secured in one of the internally threaded sleeves and an upper extent passing through one of the unthreaded aperture with an upper nut thereabove, the top of the supportive tube being in contact with the central section of the cross brace whereby the tightening of the upper nuts will lift the support bracket and loosening of the upper nuts will lower the support bracket, the support bracket thus being adapted to hold the foundation at a level desired by a user; and a pressurized grout dispensing unit coupled to the upper end of the filling tube for dispensing grout through the apertures of the supportive tube beginning adjacent to the lower end thus allowing grout to pass through the apertures of the supportive tube and fill any subterranean voids, this filling of the supportive tube and subterranean voids thereby functioning to solidify the supportive tube and produce a massive anchoring flange of the filled subterranean void which is coupled to the supportive tube to thereby add further support to the structure.
