What is a tieback easement?

Tieback easements are subterranean easements allowing the grantee to install shoring devices known as tiebacks deep underground on the grantor’s property.

Tieback Anchors. Tieback Anchors are a construction element that is used to actively apply tensile forces to structures. Tiebacks can be used on new construction or to remediate existing structures. Tiebacks can be constructed out of strands of cable or reinforcing bar grouted into the soil.

Also Know, how do shoring tiebacks work? Tiebacks are usually preferred because they keep the excavation clean and open. 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.

Likewise, what is a tieback agreement?

A tieback is a structural element installed in soil or rock to transfer applied tensile load into the ground. The tieback-deadman structure resists forces that would otherwise cause the wall to lean, as for example, when a seawall is pushed seaward by water trapped on the landward side after a heavy rain.

What is shoring in building construction?

Shoring is the process of temporarily supporting a building, vessel, structure, or trench with shores (props) when in danger of collapse or during repairs or alterations. Shoring comes from shore, a timber or metal prop. Shoring may be vertical, angled, or horizontal.

What is a soldier pile?

A soldier pile is a common retaining wall strategy in which H-shaped steel beams (“piles”) are drilled deep into the earth at regular intervals — usually 2 to 4 yards apart. Known as “lagging walls,” these horizontal supports are most often made from precast concrete panels, steel girders or pressure-treated timber.

What are rakers?

Noun. raker (plural rakers) A person who uses a rake. A machine for raking grain or hay.

How is shoring done?

For our purposes, shoring is the process of supporting the underground walls of a building or trench with props (shores) when we’re digging so that the soil doesn’t cave in during the process of creating the foundation. Once the digging is complete, the shore is lowered into the ground.

What is a raker in construction?

Raker shores are diagonal shores used to give stability to walls and sometimes entire structures; the concept is used every day in modern construction (tilt slab, for example). Each type features a wall plate, a diagonal raker post and some type of sole plate.

What is a subsea tieback?

The subsea tieback is an engineering process connecting an untapped satellite oil field to an existing production center. Connecting to smaller satellite fields within a given distance from the production facility does just that.

How do I install lag?

When the soil has stand-up time, then the lagging can be inserted from the top and placed with a downward pull. Other types of soil require the lagging to be installed on the outside of the piles continuously. When slight caving or sloughing happens, then soil or grout should be placed behind the lagging.

What is a raking shore?

Raking shores is a system of giving temporary support to an unsafe wall. The construction of raking shores, also known as inclined shore, varies with the conditions of site. The wall-plate is further secured to the wall by means of needles.

What is braced excavation?

Cross-lot or internal bracing transfers the lateral earth (and water pressures) between opposing walls through compressive struts. A typical sequence of excavation in cross-lot braced excavations is shown in Figure 1. The struts rest on a series of wale beams that distribute the strut load to the diaphragm wall.

What is soldier pile and lagging?

Soldier Pile and Lagging is an earth retention system consisting of steel piles driven or placed in drilled holes. Depending upon the geometry of the wall and soil conditions, tiebacks may be installed to provide additional lateral resistance.
