The invention discloses a yacht wharf floating bridge holding pile structure. The yacht wharf floating bridge holding pile structure is characterized in that a pile foundation is composed of three reinforced concrete prefabricated plate piles arranged in an equilateral triangle manner, and a concrete sheet inserted and connected in the part between the two reinforced concrete prefabricated plate piles; grooves are formed in the two sides of each reinforced concrete prefabricated plate pile, wherein the included angle of 60 degrees is formed by the grooves and the reinforced concrete prefabricated plate pile; the concrete sheet is arranged between the two reinforced concrete prefabricated plate piles, and the pile foundation in the shape of the equilateral triangle is formed through inserting and connecting of the two sides of the concrete sheet and the grooves; and a steel stand column is a floating bridge holding pile, wherein the bottom of the steel stand column is embedded in a bearing table, and a plurality of strengthened angle plates and embedded steel bars of the bearing table are welded into an independent positioning pile structure. Compared with the prior art, the yacht wharf floating bridge holding pile structure has high horizontal force resisting capability, the structure is simple, construction is convenient, the appearance is attractive, the different horizontalload requirements can be met by adjusting the size of an inserting plate, and the structure is particularly suitable for a floating bridge holding pile for a large-ship-load yacht wharf with the poorgeological conditions.
