PREFABRICATED MOLD STRUCTURE OF WATERWAY AND CONSTRUCTION METHOD OF DRAINAGE CANAL

摘要

PURPOSE: A prefabricated form structure and a construction method of a drainage are provided to execute drainages of various sizes by applying a form fixing frame capable of adjusting the width and height. CONSTITUTION: A prefabricated form structure comprises a pair of inner wall form panels(10), a pair of outer wall form panels(12), and an inner wall form fixing frame(20). The inner wall form panels form both inner walls(3) of a drainage(1). The outer wall form panels form both outer walls(5) of the drainage. The inner wall form fixing frame fixes the inner wall form panels to the predetermined position and comprises a pair of first clamping units(26) and a spacing member(28). The first clamping units are respectively connected to the inner wall form panels. The spacing member adjusts the distance between the first clamping units by corresponding to the distance between the inner wall form panels.
