The construction of groove shaped steel sheet piles mainly includes identifying underground obstacles, leveling the site, determining the pile position, pressing the steel sheet piles, implementing drainage measures, excavating and installing supports (or anchoring), excavating to the bottom of the foundation pit and promptly treating the foundation, constructing the cushion layer and main structure, and backfilling step by step in a timely manner. During the construction process, attention should be paid to the waterproofing of the joints to prevent soil erosion at the joints, which can cause geological collapse and instability. At the same time, it is necessary to ensure that the foundation pit itself has a certain degree of stability to prevent stability and strength damage such as overall, skirting, uplift, piping, and sand flow.
