摘要

PURPOSE: A retaining-wall-type crib is provided to reduce manufacturing cost by the minimum timber use, to simplify a construction method and to prevent the erosion of bagwork using environment-friendly timber. CONSTITUTION: A retaining-wall-type crib comprises a retaining-wall frame(10), a pipe(20) and a fixing rebar(30). The retaining-wall frame consists of a plurality of timbers(11,12), which are arranged in parallel to each other. The pipes are located at given intervals toward the shore, at which the retaining-wall frame is installed. The ends of the fixing rebar are fixed to the upper and lower ends of the retaining-wall frame and the fixing rebar fixes the retaining-wall frame and the pipe in a way of protecting the pipe.
