Abstract
A modular assembled retaining wall is constructed by placing a plurality of precast tie-back elements in laterally spaced relationship along a grade line. A novel soil retaining panel is provided. The panel includes a curved rear wall meeting a flat front wall at curved ends which mate with vertical ribs of each tie-back. A novel method is also provided for simultaneously casting two tied arch-shaped soil retaining panels out of low water-to-cement ratio concrete.
Claims2
Structure for a modular assembly for retaining soil along an embankment, comprising in combination,
- at least a pair of laterally spaced tie-back elements,
- each tie-back element comprising a web interconnecting a pair of spaced apart vertically oriented columns, each said column comprising at least one laterally projecting vertically oriented lip,
- a soil retaining panel extending between said pair of tie-back element, said retaining panel comprising,
- an arcuate rear wall,
- a substantially flat chordal front wall whose lateral extremities are integral with the lateral extremities of the arcurate rear wall, forming first and second rounded ends of the panel, and where the front and rear walls are vertically co-extensive,
- and including at least one stress web interconnecting the front and rear walls, disposed perpendicularly to the front wall, defining at least a pair of tubular passages through the panel,
- said first and second rounded ends on said panel each being disposed in mating relationship against the lip and the web on one of said pair of tiebacks,
- wherein said tie-back elements hold said retaining panel against horizontal outward movement away from the embankment under the pressure of the retained soil.
A modular retaining wall system for retaining soil along an embankment, the system comprising,
- a plurality of individual retaining wall tiers arranged one above the other and offset inwardly toward the embankment with respect to each other for holding an embankment of compacted soil and similar fill material,
- each of the plurality of such tiers being assembled from modular structures comprising tie-back elements in laterally spaced relationship with soil retaining panels extending between such space between adjacent pairs of tie-back elements,
- each tie-back element comprising a web interconnecting a pair of spaced apart vertically oriented columns, each said column comprising at least one laterally projecting vertically oriented lip,
- a soil retaining panel extending between said pair of tie-back elements, said retaining panel comprising,
- an arcuate rear wall,
- a substantially flat chordal front wall whose lateral extremities are integral with the lateral extremities of the arcuate rear wall, forming first and second rounded ends of the panel, and where the front and rear walls are vertically co-extensive,
- and including at least one stress web interconnecting the front and rear walls, disposed perpendicularly to the front wall, defining at least a pair of tubular passages through the panel.
