Precast traffic barrier soundwall
A traffic barrier soundwall includes a top portion attached to a bottom portion. The segments are reinforced by rebar, mesh, or combinations thereof. Dowel rods extend from the bottom edge of the top portion which fit into corresponding pipe sections along the top edge of the bottom portion. Grout is flowed into the pipe sections and an epoxy is applied along the length of the joining surfaces. The upper corners of each of the top and bottom portions have expansion troughs to accommodate hardware to attach the segments to adjacent segments. The bottom portion is generally T-shaped with a tapered cross-section. The footer of the bottom portion is installed under the ground level and connection plates attach the footers of adjacent segments to one another.
1. A traffic barrier soundwall, comprising:
a solid top portion disposed on a solid bottom portion, the top and bottom portion reinforced by rebar, mesh, or combinations thereof; and
wherein dowel rods extend substantially vertically from the bottom edge of the top portion, the dowel rods inserted into corresponding longitudinally extending pipe sections embedded in the bottom portion and disposed along the top edge of the bottom portion.
2. The traffic barrier soundwall of claim 1 , wherein the bottom portion has a generally T-shaped cross section comprising a stanchion wall substantially perpendicular to a footer.
3. The traffic barrier soundwall of claim 2 , wherein one side of the stanchion wall tapers outwardly toward the footer.
4. The traffic barrier soundwall of claim 2 , wherein connection plates secure the footer of the bottom portion to a footer of an adjacent bottom portion.
5. The traffic barrier soundwall of claim 2 , wherein the footer accommodates one or more brackets to attach the bottom portion to an adjacent bottom portion.
6. The traffic barrier soundwall of claim 1 , wherein the top and bottom portions each include lifting loops coextensive with the reinforcement.
7. The traffic barrier of claim 1 , wherein grout is flowed into the pipe sections.
8. The traffic barrier of claim 1 , wherein epoxy is applied at least one joining surface of the top or bottom portion.
9. A traffic barrier soundwall system, comprising:
a plurality of traffic barrier soundwall segments each comprising a solid top portion disposed on a solid bottom portion, the top and bottom portion reinforced by rebar, mesh, or combinations thereof;
wherein dowel rods extend substantially vertically from the bottom edge of the top portion, the dowel rods inserted into corresponding longitudinally extending pipe sections embedded in the bottom portion and disposed along the top edge of the bottom portion; and
wherein the upper corners of each of the top and bottom portions include expansion troughs to accommodate hardware such that the respective segments can be attached to adjacent segments.
10. The traffic barrier soundwall system of claim 9 , wherein the bottom portion has a generally T-shaped cross section comprising a stanchion wall substantially perpendicular to a footer.
11. The traffic barrier soundwall system of claim 10 , wherein one side of the stanchion wall tapers outwardly toward the footer.
12. The traffic barrier soundwall system of claim 10 , wherein connection plates secure the footer of the bottom portion to a footer of an adjacent bottom portion.
13. The traffic barrier soundwall system of claim 10 , wherein the footer accommodates one or more brackets to attach the bottom portion to an adjacent bottom portion.
14. The traffic barrier soundwall system of claim 9 , wherein the top and bottom portions each include lifting loops coextensive with the reinforcement.
15. The traffic barrier soundwall system of claim 9 , wherein grout is flowed into the pipe sections.
16. The traffic barrier soundwall system of claim 9 wherein epoxy is applied at least one joining surface of the top or bottom portion.
17. A traffic barrier soundwall, comprising:
a solid top portion disposed on a solid bottom portion, the top and bottom portion reinforced by rebar, mesh, or combinations thereof;
wherein dowel rods extend substantially vertically from the bottom edge of the top portion, the dowel rods inserted into corresponding longitudinally extending pipe sections embedded in the bottom portion and disposed along the top edge of the bottom portion;
wherein the bottom portion has a generally T-shaped cross section comprising a stanchion wall substantially perpendicular to a footer; and
wherein one side of the stanchion wall tapers outwardly toward the footer.
