What is it about?
By utilizing existing piles for the construction of new pile-foundation buildings, the demolition work involved and the amount of scrap to be disposed are mitigated.Thereby reducing the overall environmental impact. When reusing existing piles, evaluating their quality is paramount. This method is extremely advantageous for promoting the reuse of existing piles because it enables non-destructive evaluation of the soundness of underground walls using a simple procedure, which has remained a difficult task until now.

Why is it important?
The strategy of reusing existing piles can reduce the environmental impact, shorten the construction period, and reduce costs. Moreover, this strategy is advantageous as the piles need not be pulled out, thereby preventing the loosening of the soil, which further mitigates any adverse impacts on railway tunnel segments and other underground structures that may result from this loosening.
Perspectives
This strategy is advantageous in terms of a reduced environmental impact, shorter construction period, and cost effectiveness. By avoiding the fabrication and installation of new piles, the energy savings yielded are expectedly significant; this strategy attenuates CO2 emissions, thereby reducing the overall environmental impact.
