Abstract
A retention basin includes interlocking concrete vertical wall segments engaged with adjacent segments. Each segment has a vertical wall and a top edge that defines a lifting bore that is complimentary in shape to a removable lifting bolt that is configured to provide a lifting attachment point for a lifting cable and an internal bore in alignment with the internal bore of an adjacent segment. A pin is disposed in the internal bores to maintain the segments in alignment. An eyebolt includes an eye portion disposed around the pin. A plate is bolted to the eyebolt and against the vertical walls of two adjacent segments to maintain the two segments in a spatial relationship. An earth anchor is buried in the soil to provide lateral support to the segments. A post-installation attachment is affixed to the lifting bore of at least one segment.
