Composite Piles. These piles are seeing increase application throughout
the Navy. LANTDIV has prepared a regional guide specification, NFGS 02362
Composite Plastic Fender Piles, which covers their use.
2-2.9
The requirements for steel sheet piling are the same as previously established for steel
H-piling (refer to paragraph 2-2.5), except as modified in paragraphs 2-2.9.1 through 2-
2.9.4.
2-2.9.1
Splices. Use full-penetration butt welds for splices.
2-2.9.2
Connection to Caps. Embed steel sheet piles 52.3 mm (6 in) minimum
into concrete caps. The use of structural sections for mechanical anchorage of sheet
piling into the cap is neither required nor advised. However, provide stirrups (open to the
side) through the handling hole near the top of each sheet as a positive connection
between the steel sheet piles and the cap's longitudinal reinforcing. For steel channel
caps, tack-weld each sheet to the cap member.
2-2.9.3
Sleeves and Openings. Detail all sleeves and openings for utilities and
drains passing through the sheets to prevent loss of fill.
2-2.9.4
Minimum Thickness of Metal. For exposed faces of cofferdams, use a
minimum sheet pile thickness of 12.7 mm (1/2 in). Elsewhere, use a minimum thickness
consistent with the applied loading environment over the design service life of the
structure. In no case should the minimum thickness be less than 3/8 in. (38 mm).
2-2.10
Sheet Piling - Concrete. Use piling that conforms to the requirements
stated above for pre-cast, pre-stressed concrete piles (refer to paragraph 2-2.3) except as
modified in paragraphs 2-2.10.1 through 2-2.10.3.
2-2.10.1
Joints. Flush and grout joints tight to the mudline. Use of plastic sleeves is
recommended.
2-2.10.2
End of Sheets. Use sheets cast with a drift-sharpened point. Embed tops
of sheets 152.4 mm (6 in) into a continuous concrete cap.
2-2.10.3
Sleeves and Openings. The treatment of sleeves and openings in
concrete sheet piling is similar to the procedure followed with steel sheet piling (refer to
paragraph 2-2.9).
2-2.11
Sheet Piling - Timber. Use timber sheet piling conforming to the
as modified in paragraphs 2-2.11.1 through 2-2.11.5.
