Abstract

The invention discloses a screw anchor mounted suction barrel foundation. The screw anchor mounted suction barrel foundation comprises a screw anchor power mounting system, a suction barrel mounting vacuumizing system, a suction barrel and a screw anchor. The screw anchor power mounting system comprises a second motor, a power driving device and a driving shaft; the second motor and a first motorare mounted in a mounting ship; and the second motor is connected with the power driving device, and the driving shaft is driven to move. The suction barrel mounting vacuumizing system comprises a high-power water pumping pump, the first motor and a water pumping pipe; a screw anchor top cover is disposed at the top end of the screw anchor and arranged on one side of the bottom end of a top plateof the suction barrel; a screw plate is disposed on the outer ring of a screw anchor main rod; a through hole is formed in the center of a suction barrel top cover; the driving shaft penetrates through the through hole to be connected to the screw anchor top cover; a seal rubber ring is disposed between the driving shaft and the wall of the through hole of the suction barrel top plate; and the water pumping pipe is disposed on the inner side of the suction barrel and connected with the high-power water pumping pump. By means of the screw anchor mounted suction barrel foundation provided by theinvention, both high horizontal load capacity and high anti-pull bearing capacity are achieved.

Description

technical field [0001] The invention relates to the technical field of marine geotechnical engineering, in particular to a suction barrel foundation on which a screw anchor is installed. Background technique [0002] The suction barrel foundation is one of the main foundation types of offshore wind turbines and other marine engineering structures. The suction bucket foundation relies on the horizontal resistance of the soil, the self-weight of the bucket and the soil in the bucket to provide the horizontal bearing capacity, and relies on the wall-soil friction to provide the uplift bearing capacity. Pull-out failure is prone to occur under current load. Spiral anchor foundation has high pull-out bearing capacity, but its ability to resist horizontal load is poor, and it is prone to overturning damage. In order to adapt to the complex marine environment, the present invention proposes a new structure of the suction bucket-spiral anchor composite foundation based on the spir...
