An eco-friendly harbor structure using the difference of the tide level is provided to utilize harbors for field experience in education by forming a narrow channel on the inland and checking the flow of seawater if there is a difference in the tide level. An eco-friendly harbor structure using the difference of the tide level comprises: a pipeline installation section formed for field experience of marine ecology by cutting out a portion of a riprap bank of the existing breakwater, laying a pipeline which is composed of the front inclined to face the open sea, a seawater inflow hole formed on the incline, a seawater outflow hole formed for field experience of nature by opening a portion of the base of the land area and an insertion hole formed on the top to install a waterwheel and a wire net for protection of fish from the waterwheel, and placing cap concrete on the upper part of the pipeline, and then piling up wave-dissipating blocks on the top of the pipeline of the open sea; a narrow channel section(B) formed by leveling up the bottom of a seawater channel, installing bottom blocks on the bottom, paving foundation ripraps on both sides of the bottom block, placing foundation blocks on a place where the top and incline of the foundation ripraps meet and installing wave-dissipating blocks along the incline of a narrow channel; and a floodgate installation section(C) formed by installing a floodgate to control seawater of a reservoir installed on the end of the narrow channel of the inland. |
