    摘要: A rail tie and track-tie connection includes a molded plastic body member having molded plastic cover pieces attached to the body member, with lip portions engaging and capturing bottom flanges on the track rails. The body member may be hollow with a filler mass supporting the sides and cross bolts providing further reinforcement. A detector circuit for electronically detecting removal of a cover piece is located within the tie body member.

    摘要: A retaining wall construction using courses of lightweight hollow timbers molded from plastic and having interfit portions and the adjacent bottom and top edges which seal the spaces between the courses. Vertical whaler posts connected to the rear face of the timbers and connecting bars extending to the rear of the wall equipped with deadman paddles stabilize the wall. Splicer pieces are received in each set of abutting ends of the timbers and are connected to the respective timbers.
