RIVERBED CRIB AND CONSTRUCTION METHOD OF THE SAME

摘要

PURPOSE: A riverbed crib and a construction method of the same are provided to reduce distribution cost since the top and the bottom of thinned lumber become flat on the spot using a portable unit. CONSTITUTION: A riverbed crib comprises a first frame(100), a second frame(200), and a third frame(300). The first frame comprises first to third transverse members, and longitudinal members(112). The first transverse member makes the ends of the longitudinal members overlap. The second transverse member is formed on the rear of the first transverse member at a given interval in the same form to the first transverse member. The third transverse member is formed on the rear of the second transverse member at a given interval in the same form to the second transverse member. The second frame is stacked on the top of the first frame in the same form to the first frame. The third frame is stacked on the top of the second frame in the same form to the second frame.
