A common duct-cum-precast culvert assembly is provided to utilize as a culvert for flowing waste water or agricultural/industrial water through or a common duct for installing various cables by having excellent waterproofing efficiency and to cut down on the cost of construction by having excellent constructability, shortening a period of construction and reducing the required labor. The common duct-cum-precast culvert assembly(100) comprises many culvert units(110) assembled continuously to form a flow passage for flowing waste water or agricultural/industrial water through or to form a space for installing various cables and provided with one or more air exhaust grooves on the bottom to exhaust air between a culvert unit and a concrete foundation block to the outside smoothly when placing a waterproof member, grout grooves(120) formed on the front and rear of the culvert unit to form a space for filling grouting materials and provided with two or more shear reinforcement grooves retreated to be deeper than the grout grooves to fill up grouting materials thickly, one or more insert nuts buried under the shear reinforcement grooves and stud bolts coupled to the insert nuts to be buried under grouting materials filled in the shear reinforcement groove to heighten the binding strength of two culvert units, a concrete foundation block(130) assembled to form a foundation structure for installing the culvert units and provided with a connecting groove to couple with a connecting groove of another concrete foundation block to form one continuous groove and a connecting plate coupled to the concrete foundation block by many bolts to connect two adjacent concrete foundation blocks strongly, and a waterproof member placed between the culvert unit and the concrete foundation block to prevent the inflow of ground water to the inside of the culvert unit. |
