Embodiment Construction

[0024] The present invention is described in detail below in conjunction with accompanying drawing:

[0025] As shown in the figure, the integrated jacket device includes a jacket body 1 horizontally arranged on the seabed surface 3 . The jacket body 1 includes multiple jacket legs 2 . A pipe pile 4 fixed to the seabed surface 3 is inserted into each jacket leg 2 . The installation method is as follows: first insert the pipe pile 4 into the jacket leg 2 and protrude from the bottom of the jacket leg and enter into the seabed, and then use a pile driver to drive the pipe pile into the seabed for fixing. With the positioning of jacket legs, the positioning of pipe piles is very accurate. A part of the jacket body 1 is immersed in seawater 6, and the other part is placed above the sea level.

[0026] The top of the jacket body 1 is provided with a jacket platform 5 on which a fan barrel can be installed. The provided jacket platform 5 has two implementations.

[0027] One of...

Abstract

The invention discloses an integrated jacket device which comprises a jacket body, wherein the jacket body is horizontally arranged on a seabed surface; the jacket body comprises a plurality of jacket legs; a tubular pile which is fixed on the seabed surface is inserted into each of the jacket legs; a jacket platform on which a fan tower cylinder is installed is arranged at the top of the jacket body; and the jacket platform is integrally connected with the jacket body. Besides, the invention discloses a basic mounting method of an offshore fan jacket. The method comprises the following steps: A) mounting the jacket platform: arranging the jacket platform at the upper end of the jacket body and connecting the jacket platform and the jacket body into a whole; B) placing the jacket body: horizontally arranging the jacket body on the seabed; C) piling: inserting the tubular piles into the jacket legs and utilizing a piling machine to firmly fix the tubular piles in the seabed; and D) grouting: after piling the tubular piles, grouting cement plaster into the clearances between the tubular piles and the jacket legs.

Description

【Technical field】 [0001] The invention relates to a foundation installation method of an offshore fan jacket and an integrated jacket installation device. 【Background technique】 [0002] Due to the limited onshore wind resources and the increasing saturation of onshore wind turbines, the ocean has become a new site for wind power generation. For traditional offshore wind turbine jacket foundations at home and abroad, the pipe piles are usually driven to the seabed by a pile driver, then the jacket is placed, and finally the gap between the jacket legs and the steel pipe piles is fixed by grouting. [0003] The construction of this traditional jacket structure is difficult in operation, such as underwater piling, positioning of pipe piles, removal of impurities inside pipe piles, underwater grouting, and leveling of wind turbine tube bases. [0004] The present invention is made under such circumstances. 【Content of invention】 [0005] The object of the present invention ...
