While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a grout injection/structure anchoring system that allows solidifying a structure such as a house by supporting it from bedrock and filling any subterranean voids which would otherwise cause structural instability.
In this respect, the grout injection/structure anchoring system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of solidifying a structure such as a house by supporting it from bedrock and filling any subterranean voids which would otherwise cause structural instability.
Therefore, it can be appreciated that there exists a continuing need for a new and improved grout injection/structure anchoring system which can be used for solidifying a structure such as a house by supporting it from bedrock and filling any subterranean voids which would otherwise cause structural instability. In this regard, the present invention substantially fulfills this need.

SUMMARY OF THE INVENTION

In view of the foregoing disadvantages inherent in the known types of structural supports and stabilizers of known designs and configurations now present in the prior art, the present invention provides an improved grout injection/structure anchoring system. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved grout injection/structure anchoring system and method which has all the various advantages of the prior art and none of the various disadvantages
To attain this, the present invention essentially comprises an auger pipe in a generally cylindrical configuration. The auger pipe has a closed lower end in a cone-shaped configuration with rigid bit components to facilitate drilling. The auger pipe also has an open top end with male screw threads adapted to be removably coupled to a rotatable power source (not shown) for insertion of the auger pipe into the ground to bedrock. The auger pipe also has a hollow intermediate section forming a bore between the upper and lower ends. Male threads are formed along the majority of the length of the intermediate section. Apertures extend through the intermediate section for the passage of grout to exterior of the auger pipe.
Next provided is an initial sleeve in a hollow cylindrical configuration. The initial sleeve has a lower end formed with female threads adapted to removably couple with the upper end of the auger pipe after insertion into the ground. The initial sleeve also has an upper end. An intermediate section between the upper and lower ends forms a bore coaxial with, and an extension of, the bore of auger pipe for the passage of grout.
A guide sleeve in a hollow cylindrical configuration is next provided. The guide sleeve has a lower end and an upper end. The guide sleeve also has a collar extending radially outwardly from the upper end of the guide sleeve.
Next provided is a slide bracket assembly. The slide bracket assembly has a horizontal plate positionable beneath a structure such as a house to be lifted and supported.
