PURPOSE: An ultra high performance steel composite concrete manhole cover with reinforced tensile strength by having tension resistance steel at the center is provided to reduce the occurrence of noise, to exclude the anxiety about corrosion and to improve durability, to reduce the cost of construction by reducing the manufacturing cost, to remove the anxiety about robbery, and to prevent crack formation or breakdown even if tensile stress exceeding the design tensile strength of UHPC acts. CONSTITUTION: An ultra high performance steel composite concrete manhole cover(1) with reinforced tensile strength by having tension resistance steel at the center comprises: a main body(11) manufactured with UHPC(Ultra high performance concrete) to have a disk shape; and disk type tension resistance steel arranged on the bottom of the center of the main body to unify with the main body and provided with a projection buried in the main body to fulfill the function of an anchor to couple with the main body integrally. |
