Assembled type anchoring system applicable to hard seabed

Abstract

The invention discloses an assembled type anchoring system applicable to a hard seabed. The assembled type anchoring system applicable to the hard seabed is formed by assembling four components, namely a cement anchor main body, a first-stage counterweight block, a second-stage counterweight block and a third-stage counterweight block; each component is prefabricated from reinforced concrete; the components are relatively light and are convenient for transportation and hoisting, each component is in an axisymmetric cylinder shape, and a whole body with a larger bottom and a smaller top is formed after assembling. The assembled type anchoring system provided by the invention is relatively applicable to a hard seabed area, has the characteristics of heavy weight, same properties in the direction of 360 degrees and relatively low center of gravity, can adapt to storm wave action in random direction, can provide a relatively strong anchoring force and is simple in assembly and construction process; Meanwhile, the components can be hoisted and lifted off one by one according to a sequence opposite to the assembly process, the whole anchoring system is disassembled, carried and repeatedly utilized, and even an individual component and part can be replaced as required.

Description

technical field [0001] The invention relates to an anchoring system for seawater culture net cages, and more particularly, to an assembled anchoring system suitable for rigid seabed fixed net cages. Background technique [0002] The anchoring system is the foundation of the sea culture cage in the water, and plays the role of fixing and mooring the cage system. At present, there are three main types of cage anchoring systems in China: iron anchors, cement pier anchors and pile anchors. Among them, iron anchors are more expensive and suitable for sea areas with more complicated seabeds; cement pier anchors are moderately priced and suitable for sandy mud or sandy bottoms. Sea area: the price of pile anchor is relatively cheap, suitable for sea area with shallow water depth and sandy bottom. [0003] Generally, iron anchors, cement pier anchors and pile anchors can be used as anchoring systems for cages for soft seabed conditions such as silt, sandy mud or sand. However, f...

Problems solved by technology

However, for hard seabed conditions such as gravel, soft rock, and hard rock, it is difficult for the bottom surface of the cement pier anchor to fully contact with the uneven hard seabed. The friction coefficient between the hard seabed and the hard seabed is small, so the anchoring force provided by the traditional cement pier anchor is very limited, and it is difficult to fix the cage system

[0005] Therefore, in some sea areas with hard seabed conditions, because it is difficult to find a cost-effective anchoring system, it is difficult to carry out sea cage culture in such sea areas, resulting in idle and waste of sea area resources.
