Abstract
A seawall is provided by embedding perforate polymer mats within an earthen formation and securing the mats to stacked preformed concrete panels at the face of the formation. The mats are wrapped around rods and secured to the panels by capturing the rods between opposed surfaces on the panels. Seals and filter closures are disposed between the panels to shield the formation from sloughing and the intrusion of water.
Claims7
A wall for retaining and protecting the face of an earthen formation, said wall comprising:
- paired face panels stacked upon one another at the face of the formation, said paired panels having back surfaces in apposition to the formation, mutually engageable stacking columns at spaced locations along the length thereof, and surfaces opposed to one another intermediate said columns;
- a longitudinally extending groove formed in the opposed surface of at least one of said paired panels in spaced relationship to the back surface thereof;
- a recessed step formed in the opposed surface of at least one of said paired panels, said step being uninterrupted and co-extensive with said groove, said step extending to the back surface of the panel within which it is formed and communicating with and having a depth less than the groove;
- a soil reinforcing mat embedded within the formation, said mat having a distal portion extending over the recessed step and secured to an enlarged anchor captured between said groove and the opposed surface of the panel in opposition thereto;
- and seal means within the step engaged with the mat to restrict the intrusion of water through the wall and into the formation.
