Abstract
Apparatus for shoring a building foundation including spaced pilings extending into drilled bore holes such that the lower ends of the pilings rest on and are supported by a sub-stratum believed capable of supporting a portion of the weight of the foundation. Each of a plurality of pressure actuated jacks is connectable between a support bracket and one of the spaced pilings. The jacks are used to individually load test each of the pilings by application of force exceeding the portion of the weight of the foundation which will be supported by each individual piling. Load equalizing manifolds are connected to the fluid inlets and to the fluid outlets of the jacks to distribute a portion of the weight of the foundation over the pilings.
Claims8
Apparatus for shoring a building foundation comprising:
- bore drilling means movable for deposition in the proximity of the foundation for drilling a plurality of spaced bore holes adjacent the edge of the foundation and extending from the surface of the ground to a sub-stratum believed capable of supporting a portion of the foundation weight;
- piling means disposed within each of said bore holes such that the lowermost ends of said pilings rest on and are supported by said sub-stratum and such that frictional force between adjacent surfaces of said pilings and the sides of said bore holes is substantially nil;
- a plurality of support bracket means engageable with the lower portion of the foundation;
- a plurality of fluid pressure actuated jack means each connectable between one of said support bracket means and one of said spaced piling means, said jack means being adapted to individually load test each of said piling means by application of force exceeding the portion of the weight of the foundation which will be supported by said individual piling means and to distribute the portion of the weight of the foundation to be supported by each piling means and connecting means to rigidly secure each support bracket means to one of said piling means whereby a portion of the weight of the foundation is supported from said sub-stratum directly through each piling means and said bracket secured thereto;
- and load equalizing means comprising:
- common manifold means connected to the fluid inputs of said plurality of jack means;
- and common manifold means connected to the fluid outlets of said plurality of jack means.
Apparatus for shoring a building foundation comprising:
- a source of fluid;
- a hollow second pipe being threadably engageable with the upper end of a hollow first pipe, and further being adapted for engagement with a source of rotary motion for drilling a bore hole adjacent the foundation;
- a plurality of additional hollow pipes, each being threadably engageable with said second pipe and with one another and further being adapted for engagement with a source of rotary motion for drilling such a bore hole until a subsurface rock formation is encountered;
- means connecting said source of fluid to circulate fluid to remove soil cuttings from the bore hole to indicate when a subsurface rock formation is encountered;
- a fitting receivable over said pipes to form a pipe and fitting combination, said fitting being adapted for engagement with a downwardly directed portion of the foundation;
- a plurality of like pipe and fitting combinations similarly engaging other parts of the foundation;
- means for urging said fitting upwardly relative to said pipes;
- means to equalize the portion of the weight of the foundation between said pipe and fitting combination and said plurality of like pipe and fitting combinations after the foundation has been lifted and supported on said combination and said plurality of like combinations;
- and means for fixing the fitting in each combination and like combination to one of the pipes in the same combination.
