The “Easements for Seawall Tieback Anchor” (also known as the “Tieback Easement”) is an easement. that encompasses the width of the lot, beginning at the inside face of the seawall cap and running.
What does tieback mean in construction?
Tiebacks are a horizontal wire or rod that reinforce retaining walls for stability. These tiebacks are anchored on one end to the wall and to a stable structure on the other. This could be a concrete deadman that’s been driven into the ground or anchored into the earth with resistance.
What is a tieback in real estate? A tieback is a structural element installed in soil or rock to transfer applied tensile load into the ground.
How does a tieback work?
Essentially, a tieback is a massive soil or rock anchor. A tieback machine drills an angled hole through the wall, puts a large steel cable in the hole, and then pumps concrete into the hole to backfill it. The concrete bonds to the cable and acts in friction against the soil/rock to resist being pulled out.
What are rakers?
British Dictionary definitions for raker raker. / (ˈreɪkə) / noun. a person who rakes. a raking implement.
Are tiebacks permanent?
Tiebacks can be used for both temporary and permanent applications. Permanent tiebacks differ from temporary tiebacks in that the critical components of the tieback tendon and anchor head are protected from corrosion. Tie back construction can be anchored into most types of soil and rock.
What is tie back meaning?
v. To draw something backward and fasten it: I gathered my hair and tied it back in a ponytail. We tied back the curtains so that they wouldn’t blow around in the breeze.
What is the difference between soil nail and tie back?
Soil nails are bars installed within an excavation or slope to provide reinforcement to an earth retention structure. They differ from tie backs in that they are considered passive elements and are not actively loaded in tension like a prestressed ground anchor.
How are rakers installed?
A tieback is a structural element installed in soil or rock to transfer applied tensile load into the ground. Grout is then pumped under pressure into the tieback anchor holes to increase soil resistance and thereby prevent tiebacks from pulling out, reducing the risk for wall destabilization.

What is a soldier pile?
Soldier piles (beams) and lagging is an excavation support technique where vertical piles (most commonly steel piles either driven or lowered into a drilled excavation and grouted) are at regular intervals along the proposed wall location. … For excavations of small height, the walls are typically cantilevered.
What is the purpose of rakers?
Rakers are usually present in two rows, projecting from both the anterior and posterior side of each gill arch. Rakers are widely varied in number, spacing, and form. By preventing food particles from exiting the spaces between the gill arches, they enable the retention of food particles in filter feeders.
Which member is used to tie all rakers?
Raking Shoring is also called inclined shoring. It can be defined as the shoring in which the inclined members are used to provide lateral support to the unsafe structure. Such inclined members are known as the rakers or the inclined shores. Usually, the wall plates of sizes 23cm * 5 cm to 23cm * 76cm are used.
What are chainsaw rakers?
The depth gauge (rakers) on a chainsaw control how deep the cutter teeth penetrate. Because the top plate of the cutter tooth is angled back slightly, it is essential that the depth gauge be lowered as the cutter teeth are filed back.
How much do helical tie backs cost?
Helical tiebacks are the most expensive option for stabilizing a bowing wall. They cost approximately $1600-$1700 per tieback, depending on if they can be installed by machine or by hand.
What is permanent shoring?
Permanent Shoring The success of the helical shoring tiebacks has been measured over decades of use, resulting in a finely engineered earth anchor capable of a 200,000 lb. load capacity, providing an alternative to grouted anchors without the spoils and cure time.
