Apparatus for laying concrete metal pipes inverts and method for using the same

Image Number 8 for United States Patent #8096730.

An apparatus and method for repairing failed metal pipe inverts includes an apparatus for distributing concrete that is positioned at one entrance of the metal pipe invert. The apparatus includes a frame having a forward end and a rearward end. A trough is connected to the forward end, and a support arm is connected to said rearward end. One end of a chute traverses the trough, while the other is supported by the support arm. A scraper is to the chute to spread concrete distributed from the trough into the pipe invert. The concrete is poured into the chute and distributed into the trough. The apparatus is pulled through the metal pipe invert to distribute concrete from an opening in the trough onto the metal pipe invert. The scraper engages the concrete to selectively spread the concrete on the metal pipe invert and repair the invert.
