Description

Culvert structure base plate repair and reinforcement method

The present invention relates to a method of repairing and reinforcing the bottom plate of a culvert structure, and more particularly, to a method of improving the shear strength of a culvert structure by repairing and reinforcing the bottom plate of an existing culvert structure in which a floor is not installed or damaged.
