Abstract

An arch bridge system including first and second side walls, a foundation, and arch beams. The first and second side walls each include side wall sections supported by the foundation and aligned along the width of the system. Adjacent side wall sections form a column therebetween that defines an interior void extending along a height of the column. A first end of each arch beam is supported at the first side wall at an upper portion of one of the columns and a second end is supported at the second side wall at an upper portion of another one of the columns. Each interior void has reinforced concrete forming cast-in-place columns defining rigid, fixed, monolithic connections between the foundation, the first and second side walls, and the plurality of arch beams. A method of producing an arch bridge system is also disclosed.

Abstract

A retaining wall comprising at least first and second elongated framing posts laterally spaced from each other, each framing post including an edge defining a slot area. A side frame extends from a rear side of each framing post. At least one wall panel is positioned between the first and second framing posts, wherein the at least one wall panel includes opposing first and second lateral edges, each lateral edge positioned in a respective slot area of one framing post.

Abstract

A precast concrete bridge and headwall assembly includes a precast concrete bridge unit including a top wall connecting opposite side walls, and a precast concrete headwall having a bottom surface engaged on the top wall of the bridge unit and a series of earth anchors at laterally spaced intervals between the side walls. The earth anchors include a body member extending outward from the headwall to the top wall, and a foot member extending laterally outward from the body member engaged on the top wall and including an upper surface generally parallel to the top wall.
