Embodiment approach

[0036] Such as Figure 1-Figure 10 As shown, a suction barrel foundation with prefabricated concrete briquetting blocks includes an upper transition section 1 and a lower suction barrel 3. The upper transition section 1 is arranged on the upper part of the lower suction barrel 3, and several concrete briquetting blocks 2 are arranged on the lower suction barrel 3. A number of strengthening zone stirring piles 6 are set on the seabed corresponding to the bottom of the suction bucket 3, and a number of peripheral zone mixing piles 7 are set outside the strengthening zone mixing pile 6, and a ring of stiffening plates 5 is set at the connection between the upper transition section 1 and the lower suction bucket 3, and the concrete The briquetting block 2 is multi-layered and fixed on the lower suction barrel 3 through the anchor bolt assembly 4. The concrete briquetting block 2 has a fan-shaped structure. The anchor bolt assembly 4 includes an anchor rod 41, an anchor plate 42 and...

Abstract

The invention discloses a suction bucket foundation with prefabricated concrete pressing blocks. The suction bucket foundation comprises an upper transition section and a lower suction bucket, the upper transition section is arranged on the upper portion of the lower suction bucket, and the multiple prefabricated concrete pressing blocks are arranged on the lower suction bucket. According to the suction bucket foundation, the problems that in order to increase the weight of the upper transition section in an existing suction bucket foundation, the overall weight of the suction bucket foundation is increased by directly pouring and tamping concrete on the lower bucket body, however, concrete is poured on the surface of the bucket body for a long time, the maintenance time is long, the occupied area is large, meanwhile, the overall flexural rigidity of an existing suction bucket foundation structure needs to be improved by increasing the height of the bucket body, and the structural steel consumption is large can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of offshore wind power support structures, in particular to a suction barrel foundation with prefabricated concrete briquettes. Background technique [0002] In the field of offshore wind power, the suction bucket foundation is a relatively common form of foundation structure, which is usually composed of two parts: the upper transition section and the lower bucket body. The suction bucket foundation has the advantages of high bending rigidity, safety and reliability, and fast construction speed. . [0003] The suction bucket foundation needs to bear various natural environmental loads such as wind, waves, and currents during its use. In order to keep the foundation stable without excessive deformation, the foundation itself needs to have a considerable weight. At present, the common suction bucket foundation mainly increases the overall weight of the suction bucket foundation by increasing the weight of t...
