PURPOSE: A floating typed automatic guide-rail using the buoyancy is provided to automatically fall and float a guide-rail by the buoyancy when the water lever goes up so that floating materials floating by water smoothly float without being trapped in the guide-rail. CONSTITUTION: A floating typed automatic guide-rail using the buoyancy comprises a pair of post bars(100) and support bars(200). The post bars are vertically installed and fixed into a concrete surface. The post bars have a buoyant ascent space(110) opened to a direction of the support bars in the lower side. An elastic device is installed in the lower part of the post bars so that the post bars are fallen to the opposite direction of a direction where the force is received and stand back when the force is removed. The support bars are installed between the post bars. The support bars comprises a top bar(220), a bottom bar(210), and a connection member(230).
