[0004] Aiming at the defects that existing tower structures are difficult to construct on the ocean and the cost of transportation and installation is high, the present invention aims to provide a tower structure and an installation method suitable for ocean engineering. The tower structure The structure is simple, the installation is convenient, and the characteristics that the area of the foundation tray is larger than the area of the concrete gravity foundation pedestal are used. By increasing the area of the foundation tray, the requirements for the bearing capacity of the concrete gravity foundation on the natural soft soil foundation are reduced, and the overall haulage on the water is used. Can effectively reduce installation costs

Embodiment Construction
[0036] A tower structure suitable for ocean engineering, such as figure 1 As shown, it includes a concrete gravity foundation and a tower tube 10 installed on the concrete gravity foundation. The structure of the concrete gravity foundation is as follows Figure 2~3 As shown, it includes a foundation pallet 7, a concrete gravity foundation pedestal 1 mounted on the foundation pallet 7, and a guide pipe 2 installed on the top surface of the concrete gravity foundation foundation pedestal 1. Wherein, the upper half of the concrete gravity foundation pedestal 1 is a circular truncated shape, and the lower half is a cylindrical shape, and its structural size should be determined according to the upper load and the seabed foundation conditions. The top surface of the concrete gravity foundation pedestal 1 is provided with a tower collar 5 and a water-stop washer 6 . The inner diameter of the tower collar 5 should be larger than the outer diameter of the tower 10 (such as the wind...

The invention discloses a tower-drum structure suitable for ocean engineering and an installation method thereof, which are used for solving the problems of high installation and construction operation difficulty and high transportation and installation costs existing in the conventional tower-drum structure. The tower-drum structure comprises a concrete gravity foundation pedestal, a foundation tray, a guide pipe and a tower drum, wherein an injection pipe is arranged inside the guide pipe; the tower drum is sleeved on the outer side of the guide pipe; and the bottom edge of the tower drum is arranged in a tower drum collar of the concrete gravity foundation pedestal. The tower-drum structure has a simple structure, and is convenient to install; the requirement on the bearing force of a natural soft soil foundation can be met by adjusting the size of the foundation tray; and overall water haulage is adopted, so that the installation cost can be reduced effectively. The invention is particularly suitable for tower-drum structures such as sea areas with large water depths, wind generator sets and tide generator sets on soft soil foundations, and the like.
Description
technical field [0001] The present invention relates to a marine engineering infrastructure and its installation method, in particular to a tower structure suitable for marine engineering and its installation method, especially to wind power generators in sea areas with large water depths and soft soil foundations , tidal current generating units and other tower structures. Background technique [0002] The foundation structure types of marine engineering mainly include: single pile foundation, concrete gravity foundation, suction foundation, multi-pile foundation and floating foundation. Offshore oil drilling platforms mostly use multi-pile foundations, and offshore wind turbines mostly use single-pile steel structure foundations and concrete gravity foundations. At present, the concrete gravity foundation type commonly used in China is widely used in marine projects such as ports and wharves because of its huge weight to maintain the stability of structures, simple struct...
