Embodiment Construction

[0030] like Figure 1 ~ Figure 2 As shown, 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 sleeve ring 5 should be larger than the outer diameter of the tower (such as the wind turbine tower, the tidal current generator tower). When the foundation is placed on the seabed foundation with a larger inclination, the diameter of the tower collar 5 can be increased, and its diameter can be adjusted according to the inclination angle of the seabed foundation, the outer diameter of the tower, the height of the guide pipe 2 and The outer diameter and other dimensions of the upper and lower parts are calculated and obtained, so as to real...

Abstract

The invention discloses a concrete gravity type foundation applied to ocean engineering and an installation method thereof. For solving the problems of high construction difficulty and high transport and installation costs of the conventional concrete gravity type foundation, the concrete gravity type foundation comprises a concrete gravity type foundation pedestal, a foundation tray and a guide pipe; and a grouting pipe is arranged in the guide pipe, and the outer wall of the guide pipe is provided with a plurality of grouting holes communicated with the grouting pipe. The concrete gravity type foundation is simple in structure and convenient to install; the requirement of natural bearing capacity can be met by adjusting the size of the foundation tray; and the installation cost can be effectively reduced by using integral hauling on the water. The concrete gravity type foundation is suitable for deep sea areas, can be used as a foundation of a wind generating set tower, a tide generating set tower or the like, and is particularly suitable for a soft soil foundation.

Description

technical field [0001] The invention relates to an ocean engineering infrastructure and an installation method thereof, in particular to a concrete gravity foundation suitable for ocean engineering and an installation method thereof. The invention is suitable for sea areas with relatively large water depths, can be used as the foundation of towers of wind power generating sets, towers of tidal current generating sets, etc., and is especially suitable for soft soil foundations. 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 su...
