Title: Proprietary Methods


1
Proprietary Methods
  • Any of a number of patented structures/products
    sold by a licensed vendor for erosion
    control/bank stabilization purposes
  • Product testing and performance evaluation has
    usually been performed by independent
    labs/agencies/organizations/ universities/and/or
    the manufacturer.
  • Manufacturer will have case histories and
    comprehensive knowledge of their products.
  • Design knowledge or PC based computer programs
    are usually available from the manufacturer (some
    on CD).
  • Manufacturer wants your project to be successful
    (no failure of product).
  • Installation/construction oversight is usually
    available.
  • Beware if every project design requires the use
    of the same product.

Proprietary Methods
  • Sloped or Horizontal Configurations
  • Fabric-formed concrete
  • Interlocking blocks
  • Articulating Concrete Mattress (ACM)
  • Gabions (both welded and twisted)
  • Cellular Confinement Systems
  • A-Jacks, Core-Loc
  • Turf Reinforcement Mats (TRM) Erosion Control
    Blankets (ECBs)-covered in the bioengineering
    lecture
  • Deltalok System to link sandbags
  • Vertical, or Near Vertical Configurations
  • Vertical formed concrete walls (not proprietary)
  • Sheet piling (steel or vinyl)
  • Interlocking block retaining walls
  • Gabions
  • Cellular confinement systems
  • Reinforced earth with "hard" toe protection
    (example used A-Jacks)

Erosion under a foundation-dependant method
spells trouble
And the news is not good !!

Interlocking blocks come in all shapes

some have large interstices to accommodate
plantings

Articulating Concrete Mattress (ACM) Systems
  • A proprietary method, Articulating Concrete
    Mattresses are systems of concrete elements tied
    together with either UV-stabilized rope or
    stainless steel cables to form a flexible
    mattress that can be connected to other
    mattresses to form modular protection systems.
  • Different manufacturers construct elements in
    various shapes, sizes, and thicknesses. Most ACM
    systems have been lab tested, project histories
    documented, and manufacturer's support (including
    design and installation) are readily available.
  • Very versatile, can be used for bank protection,
    grade control, channel lining, cart paths, fords,
    boat launches, and as a cover for exposed
    pipelines. Many projects require a geotextile
    filter underlayer. The entire mat system can be
    buried, and/or spaces between elements can be
    vegetated.
  • ACM systems can be totally removed and
    reinstalled, an important consideration for
    pipeline repair. Can also be removed
    reconfigured for changing stream conditions
  • For grade control applications the downstream
    ends of the mat can be allowed to float" and
    then self-adjust, (hinge) adjusting to local
    scour and/or knickpoint migration.
  • Strong anchoring systems and/or deep keys at the
    upstream and upslope boundaries of the mat system
    are required.
  • Knowledgeable and experienced designers,
    manufacturers, and installers are critical to
    project success. As with many techniques, the
    devil is in the details

Mats are connected with stainless steel cables or
non-metal straps to create a unitized erosion
control system. Additional benefits of this
system are the ability to remove, replace, or
relocate, if required.

Mats can be transported by truck, barge, boat,
even helicopter.

Gabions
  • Baskets (usually 3 ft by 3 ft by 9 ft) and
    mattresses (usually 12 inches thick). A new
    innovation in baskets has either a 45 or 60
    degree sloped face!
  • Two types of basket construction welded and
    twisted.
  • Can be PVC coated to increase durability and
    resist corrosion from acid rain and chemicals.
    New this year is one constructed from stainless
    steel
  • 4 to 9 inch rock (measured along "B" axis) is
    typically used to fill baskets (smaller rock can
    be used with some baskets). Soil with a
    geotextile liner, or rock choked with soil seed
    can be used. Small large vegetation has been
    employed both in through gabions.
  • Versatile, can be used for bank protection, grade
    control, channel lining, walkways, piers,
    ingress/egress structures, etc.
  • Long-term case histories and well-understood
    performance parameters, design and construction
    oversight available from many sources, including
    manufacturers.
  • Gabions do not adjust well, solid foundation is
    critical, connections between baskets are
    important. A knowledgeable, experienced
    contractor is a must (critical for success).

Cellular Confinement Systems
  • Originally developed at WES in the 1970's to
    strengthen road foundations built on weak soils.
  • Are engineered, polyethylene, expandable,
    honeycomb-type cellular structures designed to
    improve the performance of infill materials
    (typically soil, stone, concrete).
  • Typical applications include earth retention,
    load support, slope protection, bank protection,
    low-water fords, grade control, grade/ford
    combos, livestock watering access areas, haul
    road and/or nature path construction, etc. Can
    be vegetated.
  • Available in various colors and sizes.
  • Versatile, lab tested, project case histories
    available, easy to transport and install, PC
    based design programs and manufacturer's support
    readily available.
  • Various anchoring systems available, many
    projects require a geotextile filter
    underlayment.

A-Jacks
  • Description A proprietary method, A-Jacks are
    concrete structures designed to interlock both
    vertically and horizontally in a geometric
    fashion, resulting in a somewhat flexible
    monolithic structure that is extremely hard to
    displace. Each single unit is cast in two
    pieces. When grouted together, the two sections
    form a 6-pointed structure that rests on 3-points
    and interlocks with adjacent A-Jacks. A-Jacks
    are available in a range of sizes from 2 to 10
    ft. The 2- and 3-ft A-Jacks are employed for
    stream work, larger sizes for energy dissipation
    in oceans.
  • Typical stream installation Excavate a toe
    trench at the base of the eroding bank. On small
    streams an upper row of A-Jacks are interlocked
    with two base rows. Typically a filter of either
    Fiberfil (a synthetic) or wood fibers are placed
    under the A-Jacks. Live stakes or rooted stock
    are placed between and behind jacks. When
    installed, the A-Jacks have about 40 open area,
    ideal habitat for small fishes, other aquatic
    organisms, and macro invertebrates.
  • Easily transported into tight working areas and
    assembled on-site (each half of the 2-ft sized
    A-Jack weights 39 pounds).

Looking US at the entire stream trying to flow
underneath the exposed pipeline, the first bend
downstream of a long straight stretch is hard to
repair, the water does not want to turn!!! This
stream put sediment 1,000 ft in a straight line
out into the farmers field.
