Engineering Drafts Of Sheet Pile Retaining Wall Tie Backs

Sheet pile walls are widely used for both large and small waterfront structures ranging from small pleasure boat launching facilities to large dock structures where ocean going ships can take on or unload cargo.

Engineering drafts of sheet pile retaining wall tie backs.

Tie back walls are completely different retaining walls and rely on pre stress in ties that hold back the wall thereby retaining the soil. Nicholson designed and installed a semi continuous reinforced drilled shaft soldier pile retaining wall with tieback anchors which relieved pressure on the existing wall and stabilized the slope. Permanent or large retaining walls are often tied back to an anchor wall installed at a certain distance behind the wall. Sheet pile walls 21.

Wood retaining walls 14. A tieback is a structural element installed in soil or rock to transfer applied tensile load into the ground. Segmental retaining walls 17. How retaining walls fail.

Design examples appendix a. Most sheet pile retaining walls need a supplementary support at the top in addition to the embedment in the soil. Soldier piles sheet piles secant and tangent walls to provide additional stability to cantilevered retaining walls. 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.

We have provided shoring designs for many construction projects from simplistic trench design to advanced pile and lagging design. Temporary cofferdams generally use walers and struts to cross brace the inside excavation. Construction topics and caveats 24. Tie back anchoring system.

Soldier pile walls 22. Chance helical tieback anchors are pre manufactured steel anchor elements consisting of a central steel shaft and one or more helical shaped bearing plates. Typically in the form of a horizontal wire or rod or a helical anchor a tieback is commonly used along with other retaining systems e g. The use of nucor skyline threaded bar enables the user to optimize their design by increasing wall stability decreasing sheet pile length and reducing the wall design moment.

Our ground anchor drill rig fleet consists of several dozen machines including conventional klemm 803 806 and 807 tieback machines an 80 foot stroke rocket launcher drill and custom built excavator and forklift mounted crane suspended drill basket platforms. By employing tie backs deadmen or rakers eei is able to minimize section sizes to provide cost effective solutions. Existing rockcliff bikeway retaining wall was failing at a rate of 1 inch outward every 10 days over a three month period. Sheet pile wall types construction methods advantages and disadvantages are described in this article.

The main difference between cantilever retaining walls and the other walls mentioned is the way the foundation is designed. Restrained non yielding walls 20. Swimming pool walls 18. Tie rods can be used in conjunction with a typical sheet pile retaining system to provide additional support and stability for walls that may be too high to be cantilevered.

Pilaster masonry walls 19.
