Height-adjustable marine anchorage foundation construction device

Abstract

The invention discloses a height-adjustable marine anchorage foundation construction device. The height-adjustable marine anchorage foundation construction device comprises a bucket-shaped foundationand an outer movable frame, multiple sleeves are mounted at the positions, close to the bottom, of the outer wall of the bucket-shaped foundation, the outer movable frame comprises an upper connectingring, a lower connecting ring and shaft rods connected between the upper connecting ring and the lower connecting ring and matched with the sleeves, the bucket-shaped foundation is sleeved with the outer movable frame, each sleeve is mounted on the corresponding shaft rod in a sleeving manner, when the bucket-shaped foundation is stressed, the foundation moves on the shaft rods between the upperconnecting ring and the lower connecting ring, lifting hooks are hung at the position, between the adjacent shaft rods, of the upper connecting ring, vertical rods are mounted at the positions, between the adjacent shaft rods and located on the two sides of the lifting hooks, of the upper connecting ring, the two sides of the lifting hooks are connected with the lower ends of the adjacent verticalrods through tension springs, and the lifting hooks tightly make contact with the outer wall of the bucket-shaped foundation. The outer movable frame is mounted on the outer side of the bucket-shapedfoundation, during construction, through operation, based on the outer movable frame, an anchorage foundation further penetrates into deeper seabed soil, and compared with a traditional bucket-shapedfoundation, the device has the deeper construction capacity.

Description

technical field [0001] The invention relates to the technical field of mooring foundations of deep-water net cages or offshore floating platforms, in particular to a height-adjustable marine mooring foundation construction device. Background technique [0002] In view of the special geological conditions of the seabed, since 1990, a special form of foundation for offshore platforms has emerged——barrel foundation (also called suction pile, suction pile), which is mostly an undercut with an open bottom and a closed top. Large diameter steel drums. When installing, first rely on the self-weight of the barrel in the predetermined sea area to insert part of it into the soil to form a closed space, then pump out the gas or liquid between the barrel and the soil, so that the pressure difference between the inside and outside of the barrel is formed, and it is gradually pressed into the sea. The installation is completed at a predetermined depth in the bed. [0003] Later, based o...

AI Technical Summary

Problems solved by technology

It can be seen that when using the barrel foundation as an offshore construction tool, there is a limitation: the maximum penetration depth of the barrel foundation is less than or equal to its height

However, the greater the height of the barrel foundation, the higher the cost, and the greater the surface area, the greater the penetration resistance, which is obviously not advisable.
