Problems solved by technology

[0004] However, there are still many problems in the design, construction and application of the towed anchor in the prior art, such as the anchor body bearing capacity is limited by the area of ​​the anchor plate, the penetration depth cannot meet the specified requirements, and the soft soil foundation is not conducive to the towed anchor’s bearing capacity. Issues such as the exertion of power need to be studied in depth and improvement measures should be put forward

Embodiment Construction

[0023] The present invention is further illustrated below in conjunction with the accompanying drawings and specific examples, and these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0024] A marine engineering dragging anchor that can improve the uplift bearing performance, as attached Figure 1-3 As shown, it includes the connected fluke 1 and the anchor handle 2, and the contact surface between the fluke 1 and the anchor handle 2 and the seabed soil is coated with a diffusion coating 3 that can cure the seabed soil, so as to pull the anchor In the process, the diffusion coating forms a consolidation and hardening reaction with the surrounding seabed soil to improve the pullout resistance of the towed anchor. In this embodiment, the diffusion coating 3 uses a powder soil curing agent.

[0025] In this embodiment, the anchor handle 2 specifically includes: a pair of tie rods 21 arranged from outs...

Abstract

The invention discloses an ocean engineering drag anchor capable of improving anti-pull bearing capacity. The ocean engineering drag anchor comprises an anchor claw and an anchor handle which are connected with each other, and the contact surfaces of the anchor claw and anchor handle with seabed soil are coated with a curable seabed soil diffusion coating. The ocean engineering drag anchor capableof improving the anti-pull bearing capacity has the advantages that the seabed soil around the drag anchor is solidified and hardened through the diffusion coating and a slip casting mechanism to improve the strength of the surrounding seabed soil, thereby improving the anti-pull bearing capacity; the contact area between the drag anchor and the seabed soil is increased during drag through an ejectable externally extending plate to increase the friction between the seabed soil and the drag anchor, thereby further improving the anti-pull bearing capacity.

Description

technical field [0001] The invention relates to a dragging anchor, in particular to a marine engineering dragging anchor capable of improving the uplift bearing performance, and belongs to the technical field of marine engineering. Background technique [0002] In recent years, with the increasing water depth of offshore oil and gas field development, the mooring system has become an important link in the design and construction of floating platforms. The mooring system consists of an anchor foundation and an anchor chain system. There are many types of anchor foundations. The commonly used anchor foundations include drag anchors, flat anchors, suction anchors and dynamic anchors. Among them, the drag anchor not only has a high pull-out bearing capacity and efficient anchoring performance, but also has the advantages of light weight, material saving, and easy operation. It is currently a widely used form of anchoring foundation. [0003] As shown in the invention patent tit...
