Background

The box culvert refers to a culvert built by reinforced concrete box pipe joints. The box culvert is composed of one or more square or rectangular sections and is generally made of reinforced concrete or masonry, but the reinforced concrete is widely applied, when the span is less than 4m, the box culvert is adopted, and for the pipe culvert, the reinforced concrete box culvert is a cheap substitute, and the pier, the upper plate and the lower plate are all poured uniformly. The box culvert construction generally adopts cast-in-place, sets up the bottom in the slot that excavates, pours a layer concrete bed course, with the on-the-spot ligature of reinforcing bar that processes again, props up centre form and external mold, and great box culvert generally pours the latter half of bottom plate and lateral wall earlier, and ligature lateral wall upper portion and roof reinforcing bar again prop up interior outer mold, pours lateral wall upper portion and roof. And (5) removing the formwork when the concrete reaches the strength required by the design, and backfilling the soil on the two sides of the box culvert.
