A steel sheet pile is one of the most common construction materials generally used for earth-retaining walls. These earth-retaining structures may be permanent or temporary in nature, depending on the need of the project.
WHAT ARE STEEL SHEET PILES USED FOR?
Steel sheet piles are slender structural members of varying lengths and cross sections, that are connected using interlocks at each end of the panel to make a continuous wall. Sheet piles are usually installed as part of an earth-retaining structure for slope protection, and excavation protection.
Marine structures such as jetties and quay walls use sheet pile walls to retain the backfill soil used for raising the finished floor level of the docking areas. Sheet piles also help in the mitigation of rapid groundwater seepage for these types of projects.
For most engineering projects, steel sheet piles are usually installed for falsework or temporary excavation protection applications. These include basement and tunnel construction.
The sheet piles are installed in combination with several components such as walers and struts, forming a braced cut/excavation.
Sheet pile walls may also be installed as part of a permanent earth-retaining structure such as a continuous wall to prevent the collapse of the structures above the soil that the sheet pile wall retains.
Another example of a permanent application of steel sheet pile walls are floodwall construction projects. Such scenarios often require for a cantilever sheet pile wall for a retained soil height of not higher than 6.00 meters, and an anchored sheet pile wall for higher retained heights.
STEEL SHEET PILE BENEFITS
The main advantage of steel sheet piles is its applicability for a wide variety of engineering projects.
In addition to that, steel sheet piles would potentially require less installation time as compared to reinforced concrete for retaining wall applications, where curing of the concrete would take several days prior to the next pouring activities.
Sheet piles are also generally lighter than reinforced concrete and can be transported more easily.
In addition, issues pertaining to deterioration of material quality during transport is kept to a minimum, unlike concrete, where there may be material quality issues occurring while it is being brought to the project site.
In terms of sustainability, steel sheet piles can be recovered from temporary excavation protection structures and can be utilized again for future construction projects. For permanent structures, steel sheet pile ways are also found to perform well when subjected to various loads. This is due to the high bending stresses it can withstand.
This is evident for marine structures where steel has a high corrosion susceptibility due to the presence of seawater.
