PURPOSE: A concrete pipe using a plastic cladding pipe for anti-corrosion is provided to improve corrosion resistance of a concrete layer. CONSTITUTION: The concrete pipe using a plastic cladding pipe for anti-corrosion comprises a primary plastic cladding layer(110) where wastewater flows out, a secondary cladding layer(120) formed on the outside of the primary cladding layer(110) and coupled with a concrete layer(140), a coupler(130) whose one side is fixed between the primary cladding layer(110) and the secondary cladding layer(120) and the other side is fixed to a concrete layer(140) through the secondary cladding layer(120), and a concrete layer(140) coupled with the secondary cladding layer(120) by the coupler(130).
