Free Draining Seal Device and Installation Method for Mechanically Stabilized Earth Wall Structures

摘要

A mechanically stabilized earth (MSE) wall system that permits water drainage through joints while also preventing undesirable migration of backfill through joints, thus dramatically reducing or eliminating undesirable vegetation by incorporation of a free draining seal (FDS) in panel joints, wherein the FDS structure blocks backfill but permits water migration.

1. A combination concrete barrier and free draining seal system, comprising:
a mechanically stabilized earth (MSE) wall including a first precast concrete panel, a second precast concrete panel locate next to said first precast concrete panel, and a joint spacing located between said first precast concrete panel and said second precast concrete panel; and a free draining seal interfitted within said joint spacing thereby allowing water to pass through said joint spacing while inhibiting particulate matter to pass therethrough.
