Tie Back Systems For Sheet Pile Walls

These can be seamlessly integrated into an esc sheet pile or combination wall or other types of retaining wall.

Tie back systems for sheet pile walls.

Typically in the form of a horizontal wire or rod or a helical anchor a tieback is commonly used along with other retaining systems to provide additional stability to cantilevered retaining walls. A tieback is a structural element installed in soil or rock to transfer applied tensile load into the ground. Tiebacks are drilled into the ground with a small diameter shaft. Chance helical tieback anchors are pre manufactured steel anchor elements consisting of a central steel shaft and one or more helical shaped bearing.

Esc can offer the client a full design specification according conforming to the project requirements. Most sheet pile retaining walls need a supplementary support at the top in addition to the embedment in the soil. Earth retention is simply a method to shore or stabilize soil rock that has been removed to form an excavation cut or slope. A tieback is made by first drilling a hole with an auger and then placing a bar tendon in the hole concrete is then poured in the hole and the connection with wall is made figure 3.

Different types of augers are used to drill the tieback holes. Temporary or permanent structural retaining walls use soldier piles with wood lagging sheet piles or structural diaphragm walls to resist lateral earth pressures from retained soil. Chance earth retention systems. Pin diameters are available from 3 4 through 4 1 4 diameter.

Tiebacks may be used in conjunction with a variety of retaining systems sheet piles soldier piles secant and tangent walls to provide additional lateral resistance beyond that achievable by a cantilevered wall. Temporary cofferdams generally use walers and struts to cross brace the inside excavation. Corrosion protection options are also available. A clevis can be used when tie rods are designed for angle adjustment or when access to the outer side of the sheet pile is difficult.

Esc offers the client a wide range of sizes and steel grades for tie rod system assemblies. Permanent or large retaining walls are often tied back to an anchor wall installed at a certain distance behind the wall. They can be horizontal but are typically installed at an angle of 15 to 45 degrees.
