    Abstract: A tool system is provided for aligning and plumbing a poured concrete form (e.g., a lower vertical form portion) for forming a structural column assembly of the type used for erecting building structures and the like, such as a concrete column or footing formed in situ in an earthen hole. The system includes a center line running vertical to the length of the tool and a two-way level system incorporated therein. The tool can be used to line up the lower vertical form portion with a layout string and plumb the lower vertical form portion square. A metering pole that can be locked in place is used to lower and raise the tool into and out of the lower vertical form portion, wherein the tool is completely rotatable about the metering pole. Once the lower vertical form portion is aligned with the tool, the earthen hole is back filled, thus holding the lower vertical form portion in place in the correct position.

  • Patent number: 6749372
    Abstract: An underground shell-pile continuous wall job practice, which utilizes a special drill for constructing a continuous wall underground, is initiated by sinking two coupled special drills connected together by male and female connectors fixed on the main trunks of them respectively. Then, the first special drill is withdrawn while simultaneously pouring concrete into it until the first shell pile is finished. The process of sinking special drills and withdrawing and pouring concrete to build shell piles is repeated until the whole continuous wall is finished. In this way, building an underground continuous wall is rapid, economic and effective. The special drill has a simple structure which provides for simultaneous insertion and draining of displaced soil, thereby reducing the sinking drag force. Thus, earthmoving normally required to build underground walls is reduced greatly.

  • Patent number: 6539685
    Abstract: An apparatus for lifting and stabilizing sunken or settled foundations, slabs, footings, etc. includes a lifting plate having a pipe section solidly secured thereto, for passing concentrically over the anchor pier used in such operations. The concentric lifting plate pipe precludes cocking or tilting of the plate relative to the anchor pier and foundation structure, thereby greatly improving the security of the lifting operation. As a result of the increased lifting plate stability provided by the present invention, only a single clamp is needed for securing the lifting assembly to the foundation. The clamp is adjustably positionable as required, to secure to a solid area of the foundation structure. The present system secures the plate to the pier using mechanical fasteners, thus precluding requirement for costly welding and other metal forming equipment. A method of raising or stabilizing a foundation or similar structure using the present apparatus, is also disclosed.
