The invention belongs to the ocean engineering structure foundation of an ocean engineering filed, relating to a tension leg platform integral type negative pressure type foundation. The foundation comprises four bucket foundations with the same size, shape and material which are foursquare distributed; the main bodies of each bucket foundation have the shape of a column; the bucket foundations are communicated with each other by four water-storing pipes which are arranged on the quadrate edge; electronic valves which can be controlled to be opened or closed in a way of wireless communicationmode are arranged at the connection positions between the each water-storing pipe and the top end of the bucket foundation; the center points of the four water-storing pipes are taken as top points, the foundation is internally connected with four oblique water-storing pipes which are also foursquare arranged; the each water-storing pipe and the oblique water-storing pipes are mutually connected.The invention simultaneously provides a sinking penetrating method which is used by the negative pressure type foundation. The bucket foundations can sink and penetrate at the sea floor in 24 hours, thus, the time of offshore construction is greatly shortened and is easily controlled.
