Detailed Description
The present invention provides a skidproof rigid-flexible combined type foundation plate structure, which is further described in detail with reference to the attached drawings and the specific embodiments. Advantages and features of the present invention will become apparent from the following description and from the claims. It is to be noted that the drawings are in a very simplified form and are not to precise scale, which is merely for the purpose of facilitating and distinctly claiming the embodiments of the present invention.
Example one
The invention provides a skid-proof rigid-flexible combined type foundation plate structure which is shown in figures 1 and 2. The anti-skid rigid-flexible combined type foundation plate structure comprises a closed rigid foundation plate box 1 and a flexible toe plate 2, wherein the flexible toe plate 2 is connected to the periphery of the outer side of the bottom of the foundation plate box 1; the bottom of concatenation formula stake 3 pass the middle part of foundatin plate case 1 and with the bottom fixed connection of foundatin plate case 1.
Specifically, the foundation plate box 1 comprises a bottom plate 10, a coaming 11 and a cover plate 12, wherein the bottom plate 10, the coaming 11 and the cover plate 12 form a closed box-type structure, so that the foundation plate box 1 has buoyancy. The toe board 2 and the bottom board 10 share the same board, the bottom board 10 is located at the bottom of the foundation board box 1 and shows rigidity, the toe board 2 is located around the outer side of the foundation board box 1 and shows flexibility, so that the foundation board structure shows gradually-changed flexibility from rigid to flexible, namely the rigid-flexible combined foundation board structure is formed, when the toe board 2 is stressed, compared with the foundation board box 1, the rigidity of the toe board is greatly different, the foundation board box 1 is of a box body structure and shows rigid structural characteristics, and the toe board is of a board structure and shows flexible structural characteristics; work as just gentle combination formula foundatin plate structure is fixed on coral island reef shallow water reef dish, because reef limestone exists simultaneously with coral sand and lead to when the foundatin plate structure atress is uneven, flexible toe board can freely be out of shape, avoids bottom plate 10 takes place to incline and bear the bending moment with concatenation formula stake 3, has improved the reliability of 3 works of concatenation formula stakes.
The outside of plinth board case 1 is provided with sealing valve 13, does benefit to with man-hour right plinth board case 1 carries out the leakproofness and detects, and works as can open when the plinth board case 1 damage leaks sealing valve 13 maintenance of draining.
