The foundation reinforcement system is a specialized structure and technology system for strengthening, preventing seepage, resisting fatigue, and preventing erosion of existing offshore pile foundations and newly constructed foundations. It achieves this through methods such as steel structure reinforcement, grouting reinforcement, anti-corrosion protection, and anti-erosion structures, thereby enhancing the overall bearing capacity, stability, and durability of the foundation. It is divided into three categories: structural reinforcement, material reinforcement, and protective reinforcement.

The pile driving equipment is a complete set of specialized steel structures and machinery used for precisely sinking steel pipe piles, steel sheet piles, and composite piles to the designated depth in the seabed. It includes specialized steel structure fixtures and supporting machinery for positioning, guidance, clamping, hammering, buffering, and adjustment, etc. It is the core supporting system that ensures the accuracy, safety and efficiency of offshore pile foundation construction.

The combined pile system is a composite foundation structure formed by combining two or more types of pile foundation components such as steel pipe piles and steel plate piles, and concrete piles. By leveraging the structural advantages of different pile types, it compensates for the shortcomings of single pile types in terms of bearing capacity, lateral resistance, and water sealing performance. It is an optimized pile foundation solution for complex marine geology and extreme load conditions. It includes an integrated structural system consisting of pile body combination, connection nodes, and filling reinforcement.

Steel sheet piles are plate-shaped steel components with special locking grooves. A single pile can be interlocked and spliced through the locking grooves to form a continuous and sealed retaining and water-blocking wall. They are divided into two types: hot-rolled and cold-formed. They have both temporary support and permanent structure functions and are widely used in scenarios such as anti-seepage, cofferdam construction, and foundation pit support in marine and coastal engineering.

Steel pipe piles are hollow tubular steel foundation components mainly composed of straight seam submerged arc welded pipes (LSAW) and spiral submerged arc welded pipes (SSAW). They are implanted into the seabed or land foundation through the pile sinking process and serve as the vertical core load-bearing foundation for offshore platforms, wind power facilities, and dock structures. They can be subjected to force alone or combined with other components to form composite foundations. They are one of the most widely used types of foundation piles in marine engineering.
