PURPOSE: An assembly typed culvert is provided to maintain the seal of a junction continuously by improving junction rigidity and to easily operate bonding work. CONSTITUTION: A culvert unit(1) is in a cylindrical shape integrally formed by a lower plate(10), both side walls (20) stood at both rims of the lower plate, and a top plate(30) aligned on the upper ends of the both side walls. A fitted sill(11) is formed at one end of the lower plate of each culvert unit for being upwardly cut in a specific width along the direction of a thickness from a lower surface, and a lengthened unit(13) of fit is formed at the other end for being in a stairway shape. A combining hole(23) of cable is formed in each corner area in a groove(21) storing grouting for a cable to penetrate. And each culvert unit is firmly fixed by fixing using a cable fixer while maintaining the proper tension state of the cable using a cable tension device.
