TIMBER AND LAGGING:
Timber and Lagging shall be No. 1 Southern Yellow Pine.
BACKWALL BENT PILES:
Timber Piles:
10’ Minimum Embedment into compacted backfill or into soil having a blow count greater than 6 (N>6).
Weight (lbs.)
C:
\d\projects\standards\structures\current\ready4release\2012book_draft\21600-1of7.
dgn
Ultimate Capacity greater than 18 tons.
Splices are not allowed on any timber piles.
Shipping weights and dimensions of other bridge components can be
referenced in "Acrow Panel Bridging, Series 300, Technical Handbook".
H-Piles:
12’ Minimum Embedment into compacted backfill or into soil having a
PAYMENT:
blow count greater than 6 (N>6).
Temporary Detour Bridge is to be paid for under Contract Unit Price for
Ultimate Capacity greater than 18 tons.
Special Detour. If a temporary bridge system other than that shown herein
is used, the Contractor is responsible for renting or purchasing their own system.
Shims admissible between backwall pile and cap.
Test piles are not required for backwall piles.
EXPANSION BEARINGS:
Inspect the PTFE (Teflon) layer and stainless steel plate prior to installation.
Do not use bearings that have a severely damaged or unbonded PTFE layer.
Clean PTFE of all grit and grime prior to installation.
Clean Stainless steel plate of all grit and grime prior to installation and finish to a smooth
buffed surface.
DISTRIBUTING BEAMS:
Longitudinal stops restraining the distributing beams may be lengthened or shortened to
center the distributing beam bearing on the cap beam.
The longitudinal stops are to bear on the distributing beam end frame.
EXPANSION JOINT SETTINGS:
Install the expansion joint considering the total continuous bridge length, location of
fixed bearings and ambient temperature at the time of installation, assume a 1" expansion
