The invention belongs to the technical field of movable platform installation in offshore engineering of rock soil, geology, environment and the like, and provides a novel nail type bottom hull base.The goal of improving the anti-sliding and anti-overturning capability of the whole platform is achieved. The novel nail type bottom hull base mainly consists of a bottom hull base of any one form anda plurality of anti-sliding nails. The anti-sliding nails are fixed under the existing bottom hull base in any one form; the dimension of the anti-sliding nails is determined according to the thickness of a silt layer of a target sea area; and meanwhile, the deflection-resistant requirements need to be met. The novel nail type bottom hull base provided by the invention is applicable to all movable sea platforms requiring the bottom hull base, and the anti-sliding and anti-overturning capability of the whole platform can be improved under the condition of not influencing the environment.
