METHOD FOR CONSTRUCTING A STEEL CONCRETE RETAINING WALL FOR PREVENTING EROSION OF THE COAST CAUSED BY THE WAVES AND RIP CURRENT BY FORMING WAVE AND RIP CURRENT ENERGY DAMPING SPACES IN PARALLEL TO A VERTICAL RETAINING WALL

摘要

PURPOSE: A method for constructing a steel concrete retaining wall for preventing erosion of the coast is provided to facilitate installation of various sea structures and to prevent the coast from being eroded by waves and rip current by forming a space for damping energy of the wave and rip current on the front side of a vertical retaining wall supporting the sea structures. CONSTITUTION: A method for constructing a steel concrete retaining wall for preventing the erosion of coast(36) is composed steps for setting the position of the retaining wall by measuring the eroded coast; deciding a pile driving foundation or a direct foundation work by inspecting the geology of the coast; deciding the kind and size of the retaining wall to be built by observing wave(30) of the coast and the size of rip current(29); executing a pile driving foundation work according to the inspected geology: forming a gully by excavating the coast; pouring and curing subslab concrete on the bottom side of the gully after cutting and removing a protruded upper end of a foundation pile(11) in the gully; drawing an inking line on the upside of the subslab concrete and then temporally mounting a foundation mold along the inking line; marking the height of footing concrete by drawing horizontally the inking line on the inner surface of the foundation mold; arranging steel bars in the foundation mold corresponding to the arrangement standard; curing the footing concrete in the foundation mold; drawing the inking line on the upside of the footing concrete corresponding to the structure and size of the retaining wall and then precisely temporally mounting a portion of a body mold along the inking line; marking the height of the retaining wall by drawing horizontally the inking line on the inner upper end of the body mold; completing the arrangement of the steel bars of the body corresponding to the arrangement standard while separated from the surface of the body mold at the predetermined gap; completing the temporal installation of the body mold; curing body concrete into the body mold; and filling an excavated portion around the retaining wall with soil after removing the body mold.
