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.

Trough shaped steel sheet pile is a cold-formed buckle type thin-walled steel sheet pile with a groove shaped cross-section, which has high bending resistance, shear torsion stiffness, and stability. Trough shaped steel sheet pile is a foundation steel composed of steel plates, with the characteristic of a groove shaped cross-section. It can be formed as a steel sheet pile for foundation pit support structure by overlapping or side by side.
