Construction method for seabed bionic tree protection

Abstract

The invention discloses a construction method for seabed bionic tree protection. The construction method comprises the steps that the number and positions of bionic trees are determined according to the size of an offshore wind power foundation and the area of a bionic tree protection area, and the determined bionic tree arrangement needs to fully cover the periphery of the foundation, and a certain margin is reserved; setting a construction route of the underwater robot in advance according to the position of the bionic tree; putting an underwater robot, dragging and carrying the bionic tree by the underwater robot, and sowing the bionic tree along a set route and a set sowing area. According to the method for sowing the bionic trees, the number and the positions of the bionic trees are determined according to the size of the offshore wind power foundation and the area of the protection area of the bionic trees, the bionic trees are put more accurately, and the reasonable positions enable the wind power foundation to achieve a more comprehensive anti-scouring effect; the bionic tree is a single body, the underwater robot drags and carries the bionic tree for operation, the requirement of a large workboat is omitted, and the installation cost is reduced; the underwater robot advances according to a set route, bionic trees are sown at set arrangement points, and errors are reduced.

Description

technical field [0001] The invention belongs to the technical field of anti-scour for offshore wind power foundations, and in particular relates to a construction method for protection of a seabed bionic tree. Background technique [0002] The development of offshore wind power is rapid, with the trend of large-scale organic units, expansion of the scale of wind farms and the development of wind farms to the far sea. The offshore wind power foundation is affected by scouring for a long time, and the soil structure near the foundation is easily damaged, thereby affecting the safety of the foundation. [0003] The high cost of operation and maintenance of offshore wind power in the distant sea requires the use of protective scour measures to reduce the cost of operation and maintenance. Existing scour protection methods are mainly divided into two types: entity anti-scour protection and deceleration non-scour protection. Among them, the rigidity of material such as riprap an...

AI Technical Summary

Problems solved by technology

Among them, the rigidity of solid anti-scour protection such as riprap and concrete is much higher than that of seabed soil, which may cause more serious protective scour than foundation scour, that is, the problem of "secondary scour". Non-persistent problem, high maintenance cost

[0004] The basic protection of offshore wind power is generally to actively fill the scour pit, the volume of the material must be equal to the volume of the scour pit, the installation cost is high, and a barge equipped with a large crane is required for the corresponding installation. do homework
