Modular structures, retaining wall system, and method of construction

摘要

A modular assembled retaining wall is constructed by founding a plurality of precast tie-back elements in laterally spaced relationship along a grade line. The tie-back elements include upright column means against which retaining panel means are arranged to span the lateral space between pairs of tie-back elements. Horizontal leg means of the tie-back elements project a substantial distance from the base of the column means so as to transmit soil fill pressure on the retaining panel means back into the overburden and earth's mass. The shape and length of the horizontally oriented leg means are designed to maximize friction to resist pull-out of the tie-back elements. No mechanical interconnection is utilized between the modular elements or successive modular assembled tiers. Surcharge is compacted in sequential stages during or after the completion of each tier. Each tier is spaced inwardly toward the embankment with relation to the next lower tier and the tiers overlap in elevation. The tie-back elements in contiguous tiers can be staggered laterally.
