Segmental bio-retention basin system

摘要

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.

主权项

1. A retention basin for making an enclosure in soil, comprising:
a. a plurality of interlocking concrete vertical wall segments, each segment engaged with an adjacent segment so as to form an enclosed basin, each segment having 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, each segment including an internal bore configured to be in linear alignment with the internal bore of the adjacent segment; b. a metal pin disposed in the internal bores of two adjacent segments and configured to maintain the two adjacent segments in alignment; c. an elongated eyebolt including an eye portion disposed around the metal pin; d. a plate bolted to the elongated eyebolt and driven against the vertical walls of two adjacent segments and secured to the eyebolt with a nut, the nut torqued so as to apply a predetermined tension to the eyebolt and a predetermined force to the plate so that the plate and the metal pin maintain the two segments in a substantially fixed spatial relationship; e. an earth anchor having a first end attached to the eyebolt and a second end, spaced apart from the first end, that includes an anchoring shape that is buried in the soil so as to provide lateral support to the two segments bolted to the plate; and f. a post-installation attachment affixed to the lifting bore of at least one segment.
