Sheet Pile Project
- Before
- Witter Farm manure pit before retaining wall.
- Extrusion
- Patented Z-section sheet piles were extruded using the Bio Composites Pilot Line at the Advanced Structures and Composites Center.
- Extruded Sheet Piles
- 600 lineal feet of pile was extruded for the Witter Farm demostration project.
- Trenches
- Trenches were dug and filled with gravel before sheet piles were installed.
- Cutting Anchors
- 6" x 6" wooden beam anchors for the sheet piles being cut, then attached to the concrete wall to stabilize the cantilevered retaining wall system.
- Loading Materials
- Material being loaded at the Center to transport to Witter Farm.
- Initial Instrumentation Installation
- Instrumentation started in the pvc piping was installed and attached to a computer on site to collect data.
- Sheet Pile Installation
- Placing the third sheet pile by hand, the sheet pile placement took two days.
- Tie-Back Supports
- The wall is a tied-back design, that incorporates three 1,500lb concrete blocks attached to the wall using rebar and a steel plate. Here the concrete blocks are being placed.
- Cap Installation
- Caps being placed on the retaining wall.
- Installed Cap
- Cap on the smaller retaining wall once placed.
- Wall Support Complete
- Rebar being tied down to a steel plate completing the larger of the two retaining walls.
- Instrumentation Installation
- Instrumentation installation was completed by Shane Bourgault, an Advanced Structures and Composites Center graduate student. Strain data of the piles and soil temperature will be monitored over a one-year period.
- Concrete Driveway
- Concrete driveway being poured.
- Completed Retaining Walls
- Alternate View
- A view from inside the pit.
