Abstract
A monolithic sealing load-bearing retaining wall is constructed using precast concrete bin-type modules stacked in rows. Each module has a front wall, a partition wall spaced from the front wall, at least two spaced apart front connecting walls extending between the front wall and the partition wall, at least two spaced apart rear connecting walls extending from the rear of the partition wall, and stabilizing means extending between the rear connecting walls. The partition wall preferably is formed integrally with the front connecting walls, which provide openings for horizontally extending reinforcing members in each row of modules. The front walls and partition walls of the stacked modules serve as forms for concrete poured in the spaces between them. Upon curing, the poured concrete integrates with the front walls, partition walls, associated portions of the front connecting walls, and the reinforcing members to create a monolithic sealing load-bearing wall capable of supporting bridge girders and the like and of preventing water leakage through the wall in either direction. The stabilizing means can be metal sheets or high-strength polymer webs inserted through slots in the rea…
