Coil-loop grid connection element

摘要

A connection for securing the longitudinal wires of a soil reinforcing mat to a face element for an earthen formation is provided by converging the lead ends of the wires toward one another and forming aligned coils distally on the lead ends. A pin extending through the coils secures the soil-reinforcing mat to the face element for pivotal movement relative thereto in a horizontal plane. A variety of means are provided to secure the coils against unwinding in response to tension force applied to the wires.
