ABSTRACT:
A prefabricated pre-cast culvert including a box-shaped culvert body, which is open at both longitudinal ends thereof to have opposite end surfaces, a pair of mortar grooves each formed on an associated one of the end surfaces in such a fashion that it extends along the entire length of the associated end surface, and a plurality of couplings arranged in each of the mortar grooves. Each coupling includes a pair of connecting eye bolts threadedly coupled to the culvert body. Each coupling has an eye which is aligned with an eye of a corresponding coupling provided at another culvert to be longitudinally connected to the culvert when the culverts are in contact with each other at facing end surfaces thereof. The culverts are connected to each other by a steel rod inserted into the aligned eyes along the mortar groove.
