Embodiment Construction

[0034] The technical solutions of the present invention will be described below in conjunction with the accompanying drawings and embodiments.

[0035] see Figure 2 to Figure 4 , the offshore wind power assembly cap foundation of the present invention includes a cap 1, an anchor mechanism 3 and several foundation steel pipe piles 4.

[0036] The cap 1 is a cylindrical prefabricated concrete cap. On the bottom surface of the cap 1, a number of cylindrical pile holes 11 are reserved evenly along a circle concentric with the cap 1. On the top surface of each pile hole 11 There is a grouting hole penetrating the top surface of the cap 1, and an annular anchor groove 12 is reserved in the center of the top surface of the cap 1;

[0037] The anchor mechanism 3 is a prestressed anchor cage, the height of the prestressed anchor cage is adapted to the depth of the anchor groove 12 on the cap 1, and the diameter is adapted to the diameter of the transition section 2 of the fan tower; ...

Abstract

The invention discloses an offshore wind power fabricated type bearing table foundation and a construction method thereof. The bearing table foundation comprises a bearing table, an anchor rod mechanism and a plurality of foundation steel pipe piles; the bearing table is a cylindrical prefabricated concrete bearing table, a plurality of cylindrical pile holes are preserved in the bottom face of the bearing table, and a ring-shaped anchor rod groove is reserved in the middle of the top face; the anchor rod mechanism is a pre-stressed anchor rod cage, the height of the pre-stressed anchor rod cage is matched with the depth of the anchor rod groove, the diameter of the pre-stressed anchor rod cage is matched with the diameter of a draught fan tower barrel transition section, and the pre-stressed anchor rod cage comprises a flange base plate, a lower anchor plate and a plurality of pre-stressed anchor rods; the anchor rod mechanism is embedded into the anchor rod groove and is integrally solidified with the bearing table in a manner of filling slurry into the anchor rod groove after the flange base plate is leveled; and the multiple foundation steel pipe piles are all straight piles, the tops of the multiple foundation steel pipe piles are inserted into the multiple pile holes in a one-to-one corresponding manner, and then the bearing table and the foundation steel pipe piles are solidified into a whole in a manner of filling the slurry into the pile holes. By means of the offshore wind power fabricated type bearing table foundation and the construction method, the pouring quantity of concrete on site can be obviously reduced, the construction difficulty is greatly reduced, and the construction working efficiency is improved.

Description

technical field [0001] The invention relates to the basic structure of an offshore wind power generator, in particular to an offshore wind power assembly cap foundation and a construction method thereof. Background technique [0002] The development of offshore wind power will show a trend of large unit capacity and large water depth, and the requirements for infrastructure will be higher. The multi-pile cap foundation will have a broader application prospect due to its greater structural rigidity and good bearing capacity. Since the upper part of the multi-pile cap foundation adopts the cast-in-place concrete cap, the foundation structure is relatively thick, and the cap itself has relatively high rigidity. The inclined piles are more beneficial to the structural force and resistance to horizontal displacement. [0003] Compared with other foundation forms, the main bottleneck of multi-pile cap foundation construction is the long construction period, which requires various...
