Jetties are structures that extend out from land into bodies of water. They may also be built in the middle of a body of water with some kind of access between themselves and land. They are used at the outlets of rivers, at the mouths of tidal rivers, at lagoon outlets, to aid in river regulation, and for berthing at docks. They are also useful in ocean areas where dredging is not possible along the shore. A jetty’s main job in most cases is to influence the tide or current in an area to protect a beach or harbor from waves. When it is constructed at the bank of a river, it may serve to narrow a wide channel in order to control the current and make the channel navigable by boats and vessels.

CONSTRUCTION

Jetties are typically constructed across a slope, and they allow vessels and barges to berth alongside them or at their ends. Most constructions of jetties involve a pile structure that supports a deck. The pile structure is frequently made up of battered steel sheet piles that are driven into the ground. It may also be made up of timber or concrete piles. A jetty’s deck is often made up of reinforced concrete or steel.

MATERIALS

Steel H-piles are a popular choice for jetties. Their pile structures may also be made up of tubular piles that are spirally welded. In some cases, a jetty may necessitate a double sheet pile wall that includes at least one anchor level. As mentioned, timber or reinforced concrete piles may also be used in the construction of a jetty. Timber is most likely to be used for temporary jetties. It weathers faster than alternatives and isn’t suitable for use in rocky areas. Concrete piles can serve many of the same purposes as steel, but steel is still the preferred choice in many situations due to its relatively inexpensive price tag, longevity, and strength.Steel is also the most common type of sheet pile used in jetty construction because it can support heavy loads, offers superior water tightness, and can easily be driven into rocky ground. It’s also fairly easy to lengthen structures made of sheet piles by interlocking them using welding or bolting, which makes construction quick and efficient.

Sheet Piles in Groin Construction

Sheet piles are also used to construct groins, which serve similar functions to jetties. A groin is a narrow structure of considerable length that extends into the water from a beach area to help prevent erosion of the beach or to aid in trapping and collecting sand that would have, without its interference, drifted along the face of the beach when waves approached the beach at particular angles. A group of groins may be built to help prevent downdrift erosion, and this group of groins may be referred to as a groin field. As is the case with jetties, sheet piles are often used to build a groin’s supportive foundation. Groins are usually constructed vertically to the line of the shore and may be designed to be either permeable or impermeable, depending on the needs of the area. Steel sheet piles are well-suited to building groins that are impermeable due to their superior water tightness.Overall, steel sheet piles are a versatile option for projects that aim to protect harbors and beaches from both water damage and damage from erosion.

Sheet pile is useful in the construction of both floodwalls and seawalls. Its role in these walls helps prevent damage to land areas and properties as a result of storm surge and flooding. Storm surge is caused by offshore winds that propel water upward against the coast when barometric pressure decreases. Seawalls help mitigate potential issues caused by storm surges. Flood walls are vertical barriers that are built to contain water in rivers or waterways that are prone to overflowing during heavy rain. They are an alternative to levees and dikes, and they are often cheaper and less time-consuming to construct.In the cases of both seawalls and floodwalls, steel sheet pile is used to create the barriers that ultimately contain water from reaching areas where it could cause damage. Sheet pile is almost entirely impermeable and is an ideal material to use to build these walls. Sheet piles are often the main materials used in the construction of seawalls and floodwalls, unless concrete is used as well. The walls can be built of sheet piles entirely, though. If a wall needs to be particularly tall or if the scour needs to be deep, sheet piles can be attached to a secondary wall for support.

APPLICATIONS

Floodwalls made of sheet piles may be constructed around important facilities such as power plants, wastewater treatment plants, refineries, and other public utility compounds. Floodwalls around these facilities help prevent damage to them due to major storms and flooding so that the public does not have to do without utilities when they are needed most. Floodwalls to protect these facilities are often built to be able to contain at least 15 feet of water. If there is weak soil in the area, piles can be battered and placed on the interior of the wall for additional support, or a double wall can be used for added strength.

DOUBLE AND GRAVITY WALLS

Double walls are fairly simple to build. They make use of sheet piles to serve as a cutoff wall, which can reduce the amount of water that leaks beneath the wall. Double walls are often made using Z piles and have filled interiors. A double wall is commonly connected with a tie rod. An alternative to a double wall is a gravity wall. A gravity wall is composed of flat sheets of diaphragm or circular cells. Sheet piles used to build a gravity wall are often shorter than those used to build other types of walls. Gravity walls do not require any time of anchoring and are ideal for shallow, rocky ground areas.

T-WALLS

T-walls are a type of flood wall that is constructed of both reinforced concrete and steel sheet piles. This type of wall is popular in areas where extensive flood protection is needed, like New Orleans. The reinforced concrete serves as the primary material used to create the wall, and the steel sheet piles serve as a cut-off for the wall at its base. The sheet piles help prevent seepage beneath the wall. T-walls are particularly effective at applying loadings to deeper soil strata and being resilient in the event of overtopping. L-walls are an alternative to T-walls and another popular flood wall type. They differ from T-walls due to the fact that they use steel sheet piles to replace the reinforced concrete on the side of the wall that faces potential flooding.

FINAL THOUGHTS

As you can probably tell, sheet piles are essential to floodwalls and seawalls. Even if additional materials like reinforced concrete are required to build a wall, sheet piles are frequently necessary to the formation of cut-off walls to protect from seepage.

Each side of the section measures 3’-0” wide, with a top section measuring S6 x 12.5” x 5’-11-1/4”. The notes include instructions to see steel plate details for more information.RCP size varies based on depth.Bending DiagramThe bending diagram outlines measurements for Bar C (J-hook) at 10” C/C. The long-end length of the bar varies with differential grade (see chart below). The radius of the hook is 2-1/2”, the short end of the bar measures 6”, and the distance between the long end of the bar and the short end of the bar is 5”.Bending Diagram Bars A & BThe #5 deformed reinforced bar has a radius of 2-3/4” (interior) and an exterior radius of 8” or 168 degrees. The length of bar A is 49-1/4” and the length of bar B is 36-1/2”.Section C-CAccording to section C-C details, transitions should be backfilled with sand. Barriers include a ½” expansion joint, #5 bars and a 4” conc. Div. strip (on bridge pier transition only).Detail Expansion JointThe barriers are filled with ¾” pre-molded expansion material. There is a ¾” chamfer on all edges and a 2” clearance (minimum) from reinforcing steel to the nearest face.Section D-DAll vertical stirrup and horizontal reinforcing steel should overlap a minimum of 24” at splices and have a 2” clearance (minimum) from reinforcing steel to the nearest face.There is a grade elevation of 1-1/2” (max.) permissible offset between grade elevations.Des. 1 quantities / ft. are as follows:

• CONC. (CY) = 0.159
• STEEL (LBS) = 4.17

Plan of Delineator PlacementDelineators should be placed at 50’-0” centers along the top of median barrier; skew delineators 15 degrees to improve reflectivity.This blog post is an interpretation of specifications by the Oklahoma Department of Transportation.

The Tennessee Department of Transportation’s general instructions are as follows:

1. Precast concrete barriers should be constructed with Class A concrete manufactured in accordance with Section 604 of the Standard Specifications.
2. Reinforcing steel should be ASTM A615.
3. The connector pin should be a 1-1/4” x 25-1/8” F1554 Grade 36 anchor bolt or 1-1/4” x 25-1/8” A307 Grade A bolt. The connector pin, top connector, bottom connector, nuts and washers should be galvanized in accordance with AASHTO M-111. This standard depicts the traditional pin and eye connection details. Any Federal Highway Administration approved, NCHRP 350 compliant connection, such as the J-J hook positive connection, may also be used.
4. Place all steel reinforcement 2” minimum from the outside face of the barrier, except as otherwise shown.
5. Payment will be made under item number designated on the plans for bridge mounted interconnected portable barrier rail (per linear foot).
6. Any salvable value of the portable barrier rail will become the property of the contractor. The portable barrier rail should be moved off the project in a manner and time suitable to the engineer.
7. When interconnected portable barrier rail is fabricated in the upright position as shown on this drawing, the VB400 lifting bar will become optional and may be omitted from the installation.
8. This barrier has been successfully tested to the requirements of NCHRP 350. The contractor may submit alternate barriers that have been approved by the Federal Highway Administration as NCHRP 350 compliant. The alternate barriers must be certified by the contractor as having been fabricated in accordance with the approved alternate details.

Different section lengths and different approved connections can be used on a specific project (refer to general notes H and C above). Only one section length and connection type should be used in a single run of interconnected portable barrier rail.

Tennessee barriers should conform to the following specifications, according to the Tennessee Department of Transportation.Plan ViewBarriers include ¾” diameter concrete anchors for mounting vertical panels. Their corners form to a ½” bevel or radius. They measure 2’-3” wide. The distance between the edge of the barrier and the farthest end of the loop bar is 2-1/2” maximum (typical).Barriers include anchor bolt holes that are 2” in diameter. The first anchor bolt hole is spaced 2’-0” from the left end of the barrier; spacing after that depends on the length of the barrier:

• 2 SPA. @ 4’-3” = 8’-6” (12’-6” Section)
• 4 SPA. @ 4’-3” = 16’-0” (20’-0” Section)

Elevation ViewEach barrier is 20’-0” long and includes two 6” lifting slots, which are set 3’-4” when measured from the center of the slot to the nearest outer edge of the barrier.On the left side of the barrier, the bottom connector is spaced 6” from the ground level and the upper connector is spaced 6” from the top of the barrier. On the left side of the barrier, the bottom connector is spaced 8” from the ground level and the top connector is spaced 8” from the top of the barrier.Each barrier includes one bar A600, two bars A601, bars A400, bar VB400, bar X600, four bars C400 (on each side), and bars U400.

• Bar C400 is an L-shaped bar that measures 2’-4” (long end) and 4” (short end)
• Bar U400 is a U-shaped bar that measures 2’-4-1/2” tall, 1’-8” wide (large end) and 5-1/2” wide (short end)
• Bar VB400 is a V-shaped bar that measures 10” long on each side and a total of 9” wide for the entire bar
• Bar X600 is a U-shaped bar that measures 1’-11” (longways) and has a total width of 8”

Lifting Hole and Slot NotesTwo 2” diameter lifting holes are required for each section to be placed 3’-4” from either end of the barrier rail. Additional holes may be added to 20’-0” section lengths. Placement of additional holes to be at the discretion of the fabricator, formed with 2” PVC pipe or equal.Lifting bars are required to prevent spalling of concrete around holes.End ElevationBarriers measure 2’-3” wide on the bottom, 9” wide at the top and stand 2’-8” tall. They include ½” bevel or radius at their top edges and a 10” radius at the break point.Clearance NotesIf 4’-0” of clearance from the toe on the backside of a barrier to the edge of the slab is available then no anchor bolts will be required.Connector PinConnector pins measure 2’-1-1/8” long and include a 1-1/2” threaded end that is fitted with a 1-1/4” heavy hex nut plus a steel washer (F436 typ.). Connector pins are 1-1/4” diameter steel bar F1554 Grade 36.Bottom ConnectorBottom connectors should be galvanized after forming. They are made of ¾” diameter steel bar ASTM A36 and include a 7/8” radius on the closed side. The open side measures a total of 9-1/4” wide.This blog post is an interpretation of specifications by the Tennessee Department of Transportation.
