Abstract

Calculate the length of the bridge girder into sections according to the size and suitability of the transport according to the conditions and the terrain. And tie the iron frame According to the beam that is divided by placing the pipe that will be wire inside, string the wire into and proceed to casting the concrete according to the design that was built, casting in part 1 first, then remove the cast piece to make the design of the next part until complete casting. All pieces were used for storage, curing until the concrete was possible, so they were moved to the construction site. Take a piece of The cast beams are placed along the same line according to the numbers made. Mark on Apply a special glue along the joint.
