AN 8" THICK REINFORCED CONCRETE SLAB WILL
COVER THE EXPOSED UPSTREAM DAM FACE
BETWEEN THE TOP OF THE NEW SHEET PILE WALL
AND EITHER THE PMF ELEVATION OR THE (E)
RETAINING WALL CONCRETE. A CONCRETE
CLOSURE WILL FILL THE GAP BETWEEN THE NEW
SHEET PILE AND THE CONTROL WORKS CONCRETE
ABOVE THE ELEVATION OF THE TOP OF THE (E)
MP101 CUTOFF WALL.
NOTES:
1. THE SHEET PILE AND CONCRETE WORK INDICATED ON THESE 65% DRAWINGS IS NOT
INTENDED TO BE A PERFORMANCE SPEC, RATHER THE DETAILING HAS YET TO BE
COMPLETED. CONCRETE WILL BE A 4,500 PSI, LOW-SLUMP MIX TO ALLOW
PLACEMENT ON SLOPE. CONCRETE STRENGTH DRIVEN BY DURABILITY
REQUIREMENTS SUB-ARCTIC EXPOSURE. PVC WATERSTOP WILL BE USED AT
CONTROL JOINTS. FIELD WELDED HEADED ANCHOR STUDS WILL BE USED TO TIE
CONCRETE TO TOP OF SHEET PILE WALLS. CONCEPT WILL BE SIMILAR AT NORTH
SIDE OF CONTROL WORKS. USE OF SHEET PILE TO COMPLETE THE BARRIER WALL IN
THESE AREAS WILL ALLOW STRUCTURES NEAR THE CONTROL WORKS, SUCH AS
EXISTING SLABS AND RETAINING WALLS, TO REMAIN IN-PLACE.
2. CHOOSE (E) MP101 PILE TO BE PULLED TO MATCH INTERLOCK THUMB AND FINGER
ORIENTATION OF NEW SPLICE PILE TO ALLOW CORRECT MP101 TO PS 31 PILE
