BIN WALL – WHAT IS IT?

• live load surcharges (vehicular & rail)

• dead load surcharges (backslopes)

Armtec’s stability analysis is limited to:

FS against Sliding & Overturning

Maximum Anticipated Toe Pressures (foundation).

BIN WALL – GETTING FAMILIAR

3048mm (10’)

Wall heights are increments of 16” (406mm) starting at 4’-4” (1320mm)

WALL CONSTRUCTION-WRAPPED FACE

1. Check level of base

2. Check all line, grade and curves

3. Place removable form at front of reinforced mass

4. Install first layer of geotextile over removable form

Removable form

Geotextile Reinforcement

Native Soil

44


1. Pull Geotextile tight, keep tension applied

until backfill is placed.

Compacted fill

Native Soil

Depression for geotextile wrap

Removable form

2. Place backfill in specified lifts and compact

to 95% Standard Proctor Dry Density.

CONSTRUCTION

45


1. Wrap geotextile back over compacted fill

2. Place & compact fill above upper wrap portion and level

Native Soil

Fill on top of geotextile

CONSTRUCTION

46


1. Place second removable form by repeating step 2.

(provide required batter with set back)

Native Soil

2. Place second layer of geotextile and reinforced

fill by repeating steps 3 through 4.

3. After completion of second lift, remove the first form.
