A culvert end guard for use in surrounding and protecting an exterior end portion of a culvert and which is assembled from first and second like half shell sections is disclosed. Each half shell is T-shaped in configuration and includes a central limb portion, two end limb portions, an exterior surface and an interior surface. The interior surface of each half shell is further characterized by an open-ended channel of predetermined size and shape that is centrally disposed in and which extends in a direction along the central limb portion, and contact areas located on either side of the channel. When the first and second half shell sections are brought together in opposed and closed shell relationship, they engage one another along their respective contact areas and form from their respective channels a passageway through which the end of the culvert can extend.
A culvert guard half shell formed from precast concrete for use with another like half shell and which when said half shells are mated together one on top of the other in opposed and closed shell relationship, form a passageway therebetween for surrounding and protecting an exterior end portion of a tubular culvert;
A culvert end guard for use in surrounding and protecting an exterior end portion of a tubular culvert and which is assembled from first and second like half shell sections formed from precast concrete, wherein each said half shell is T-shaped and has a central limb portion, two end limb portions, an exterior surface and an interior surface, said interior surface being further characterized by an open-ended elongate channel in the form of a half pipe which has a radius that is no less than the exterior radius of said tubular culvert, that is centrally disposed in and which extends in a direction along said central limb portion and contact areas located on either side of said channel, whereby when said first and second half shell sections are brought together one on top of the other in opposed and closed shell relationship, they engage one another along their respective contact areas and form from their respective channels an elongate passageway for said culvert.
