2 TRICON TM RETAINED SOIL WALL SYSTEM The Tricon TM Retained Soil Wall System is a mechanically stabilized earth retaining wall structure comprised of a cast-in-place leveling course (by others), precast concrete fascia panels, panel alignment shims, HDPE bearing pads, filter fabric and adhesive joint materials, connection anchors, locking rods, hot-dipped galvanized welded wire soil reinforcement mats combined with a select backfill mass (by others). Included with the system are engineered design and erection drawings, precast concrete copings, as well as limited on-site technical assistance as required. Figure 1 below illustrates the installed system.

5 Delivery, Storage and Handling Soil Reinforcement Mats- Mats are supplied in bundles, by size and tagged with description. Mats should be stored on wooden dunnage. Mats should be color coded by size to help identify easily. Wall Panels- Unloading- Panels can be unloaded individually by using a four point lift with slings. Panels should be stacked four high on level ground. The panels are shipped stacked four high and can be unloaded by stack using nylon slings. Storage- Panels should be stored on adequate dunnage as near to the final setting position as possible on firm, level ground. Dunnage should maintain vertical alignment to eliminate the chance of the panel being damaged. When lifting panels off storage stack, always place a wooden block between panels to prevent damage when rotating to vertical position. (See Figure 6) FIGURE 6 4

6 ERECTION PROCEDURE I. Leveling Course Construction Layout the leveling course on the centerline and grade of the wall panels as provided by the project drawings. Course dimensions are detailed in the supplied erection drawings. Typical course is 6 inches thick and 12 inches wide. Finish leveling course to a smooth trowel finish. LINE AND GRADE MUST BE HELD TO 1/4 TOLERANCE. 5

7 II. Setting B Panels Snap chalk line on leveling course along the face of the panels. Place first B panel. Closely check for horizontal alignment and vertical plumb. A 1/4 back batter is recommended. Use wooden wedges and/or shims as required. Brace panel with 2 X 4 lumber for vertical alignment. Set second half B panel at a typical 3/8 spacing. Align, shim, and brace panel. 1D 1C 1B 1A Use clamps to secure First and Second panels together. Set remaining B panels in wall as described in C & D above. Install supplied filter fabric with adhesive over the vertical and horizontal joints. Make sure to cover the joint between the panel and leveling course. 1A. Cast or place leveling course on prepared foundation. Compact void on back face side. 1B. Layout proper panel face alignment on leveling course. 1C. Place and plumb bottom row of panels. Use plastic shims as required. If excessive shimming is necessary, please notify engineer. 1D. Cover all vert. and horiz. joints with filter fabric. 6

8 III. Backfill Place and compact the first lift of specified backfill up to the first row of soil reinforcement mats. Use hand operated compactors within 3 feet of the panel. Place soil reinforcement mats into the wall connectors and install the locking rod. Ensure both transverse bars on mats are placed between the panels and connectors. Wooden Wedge Remove slack in mat by using a wooden wedge between the panel and transverse wire. Continue installing and compacting backfill in specified lifts to the next level of connectors. (Do not operate tracked equipment on reinforcing mats. Equipment with rubber tires can be used, but with extreme caution.) 2D 2A 2E 2C 2B 3 2A. Place 1/2" Bearing pads (before beginning backfill) 2B. Place and compact backfill to level of first panel anchor. 2C. Place soil reinforcing mat and secure with locking rod. Remove slack in mat and connection. 2D. Place and compact backfill to top of panel. Start from end of mat and work toward panel. 2E. Backfill and compact toe at face of wall. 7

9 IV. Installation of Second and Following Panel Courses Always backfill to the top of the prior course before setting the next course. Remove clamps one panel at a time. Remove wooden wedges from panel face. Place supplied bearing pads on top of the panels in the preformed bearing pad pockets. Set A panel in place. Check spacing, and the horizontal and vertical alignment of the panel. Set joint clamps. Install supplied filter fabric with adhesive over the vertical and horizontal joints. Install backfill and soil reinforcement mats as described in Step III Backfill. Check the vertical alignment. No bracing should be required for the remainder of the wall. Backfill front of the wall above the leveling pad according to the plans. 3C 3C 3B 3A 3A. Place bearing pads at top of panel. 3B. Place and plumb next lift of panels. 3C. Place bearing pads. 3D. Repeat sequence 2B thru 3C until wall elevation is reached. 8

10 V. Final Completion of the Wall Install T panels as described in Step IV Installation of Second and Following Panel Courses. Complete backfill and compaction. Remove all bracing, clamps, and wedges. Form and pour the level-up course to accept precast coping, or form and pour coping in place as specified. 9
