ANTI-CORROSION BUCKET FOR A CONCRETE MANHOLE, MADE OF SYNTHETIC RESIN WHICH IS STRONG ON CORROSION

摘要

PURPOSE: An anti-corrosion bucket for a concrete manhole is provided to improve the quality of a concrete manhole by being made of synthetic resin having chemical resistance and corrosion resistance. CONSTITUTION: An anti-corrosion bucket for a concrete manhole is constituted as follows. The circumference of a cylinder(201) and the outer surface gradually increases from the bottom to the top. The anti-corrosion bucket is formed with an inlet(203) and an outlet(204). An inverter(205) formed in a sewage groove is inclined along the inlet and the outlet. A joint(207) is formed on the lower surface of the inverter. A lid(208) is installed on the top of the cylinder.
