Abstract
The invention discloses a positioning device for a submarine building, consisting of an anchor bar and an anchor umbrella, wherein, the anchor umbrella is positioned at the bottom of the anchor bar; the open anchor umbrella takes the shape of an inversed umbrella. During the process of submarine sinking, the anchor umbrella is folded tightly, and a framework of the anchor umbrella of the positioning device is separated from a jack and stretched out in the shape of the umbrella until the predetermined position is reached. The power of the positioning device for injecting into the seabed is vibration of a high-frequency micro-amplitude vibration source which is arranged on the top of the anchor bar, and the vibration frequency is more than 50 hertzs. Under the action of high-frequency micro-amplitude vibration, a hardened silt structure is damaged, generates liquefaction and forms slurry with fluidness, thereby the device can run through smoothly; and silt with fluidness is easy to pass through an open screen of the anchor umbrella so as to make the anchor umbrella automatically open. After the anchor umbrella is opened, a large-area structural plane is formed; and the deadweight of soil bodies on the upper part of the structural plane provides strong anti-floating force, and soil bodies on the lower part of the structural plane limit the sinking action of the positioning device. The positioning device for the submarine building has simple construction technique, easy operation, short construction period and low manufacturing cost.
