When performing temporary earth retention in soft ground, the extraction of steel sheet piles can significantly impact nearby houses and buried utilities, leading to many cases where they are left in place. Additionally, in the construction of reservoirs and river embankments, the risk of embankment failure during floods caused by water channels created during extraction is a concern. This method has accumulated approximately 200 successful cases as a solution to these issues. A new technology has been patented and registered with NETIS, which involves filling the voids created during extraction with a special filling material simultaneously as the steel sheet piles are pulled out. This helps prevent business losses and reduces costs.
