Abstract
An earth retaining wall and method having at least a pair of tiers of side-by-side blocks which define a receiving channel for a connector bar with spaced-apart keys that engage apertures in a lattice-like grid extending laterally from the tiers, the grid being covered by backfill for interlocking the backfill with the retaining wall, the keys distributing the load of the backfill evenly across the wall.
Claims6
A connector bar for engaging a grid-like sheet which extends laterally of an earth-retaining wall for receiving earthen backfill, the connector bar comprising:
- an elongate member;
- a plurality of spaced-apart block-like keys extending from a first surface of said elongated member;
- and
- the elongated member sized for being received in a channel defined in blocks stacked for an earth retaining wall,
- whereby the keys of the connector bar engage apertures in the grid-like sheet for transferring backfill load imposed on the grid-like sheet substantially uniformly to an inner side wall of the channel.
A connector bar for being slidably received within a channel defined in blocks stacked together to form an earth retaining wall and for then engaging a grid-like sheet extending laterally of the blocks for receiving earthen backfill, the connector bar comprising:
- an elongate member;
- a plurality of spaced-apart keys extending from a first surface of said elongated member, each key having an arcuate face for conformingly engaging an arcuate inner end of an aperture defined in a grid-like sheet disposed laterally of the blocks,
- whereby the connector bar with the keys being engaged to the apertures, transfers a backfill load from the grid-like sheet substantially uniformly to the blocks.
A connector bar for being slidably received within a channel defined in blocks stacked together to form an earth retaining wall and for then engaging a grid-like sheet extending laterally of the blocks for receiving earthen backfill, the connector bar comprising:
- an elongate member;
- a plurality of spaced-apart block-like keys extending from a first surface along a side edge of said elongate member, each key having an arcuate face for conformingly engaging an arcuate inner end of an aperature defined in a grid-like sheet disposed laterally of the blocks and an opposed face coplanar with a side face of the elongate member for abutting contact with a side wall of the channel, the member wider than the keys for defining an upper planar surface for receiving an end transverse rib of the grid-like sheet,
- whereby the connector bar with the keys being engaged to the apertures, transfers a backfill load from the grid-like sheet substantially uniformly to the blocks.
