Competitive Price 400 Thick Corner Piles Steel Sheet Piling for Cofferdam Soil Retaining

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.

The construction of 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 carrying out foundation treatment, constructing the cushion layer and main structure, and gradually backfilling in a timely manner.

Steel sheet piles are widely used in docks, unloading yards, embankments, retaining walls, breakwaters, diversion embankments, shipyards, gates, etc. In emergency situations such as flood control, collapse prevention, and quicksand prevention, steel sheet piles can also quickly build temporary water and soil retaining structures, effectively responding to disasters.

Steel sheet piles are also widely used in municipal engineering, foundation pit support, road widening retaining walls, isolation facilities, load-bearing foundations, and other engineering projects. Its unique performance and wide range of applications have made steel sheet piles highly favored in the engineering industry.

Steel sheet piles can be divided into various types according to their cross-sectional shapes, such as straight plate, groove, Z-shaped, U-shaped, H-shaped, etc. Among them, U-shaped steel sheet piles are the most widely used in China. Steel sheet piles can be divided into two types according to production technology: cold-formed steel sheet piles and hot-rolled steel sheet piles. Hot rolled steel sheet piles dominate the market due to their high strength and stable size. Cold formed steel sheet piles, on the other hand, are made of thinner sheets (commonly ranging in thickness from 8mm to 14mm) and processed by cold forming machines, which have the advantages of convenient production and customizable length.
