Larssen steel sheet piles, also known as U-shaped steel sheet piles, are a new type of building material. They are used as retaining walls for soil, water, and sand in bridge cofferdam construction, large-scale pipeline construction, and temporary drainage ditch excavation. They are also used as siding, retaining walls, and riverbank slope protection in ports and loading and unloading yards.

They play a key role in engineering projects. Larssen steel sheet piles for cofferdam construction are not only environmentally friendly and environmentally friendly, but also offer rapid and cost-effective construction and excellent moisture-proof properties.

Do you know what methods are available for waterproofing and moisture-proofing Larssen steel sheet pile cofferdam construction? The following describes the main steps: ensuring the flatness of Larssen steel sheet piles, using a vibratory pile driver to drive the Larssen steel sheet piles, and ensuring a satisfactory level of butter inside the Larssen steel sheet pile lock to ensure high-quality locks.

The Larssen steel sheet pile cofferdam construction design utilizes the water absorption effect of running water to draw coarse sand, sawdust, and concrete into the gaps between the leaking Larssen steel sheet piles, compacting them and achieving a waterproofing effect.

If water seepage is detected during the suction pumping process, a mixture of coarse sand, sawdust, and concrete is immediately added. A sealing hose is then installed on both sides of the steel sheet piles above the leak. The sealing hose is then lowered into the desired patching area, drawing coarse sand, sawdust, and concrete into the gaps between the leaking steel sheet piles and compacting them, achieving a waterproofing effect.
