Seabed scouring preventing bionic system and construction technology and application thereof

Abstract

The invention discloses a seabed scouring preventing bionic system and a construction technology and application thereof. Bionic water plant leaves, an installing base pad, a plurality of anchor beltsand anchoring devices are included. The bionic water plant leaves are fixedly laid on the installing base pad, and the installing base pad is connected with the anchoring devices through the multipleanchor belts, wherein the anchoring devices are used for being fixed to a sand bag layer or seabed sediments. The bionic water plant leaves, the installing base pad, the multiple anchor belts and theanchoring devices are combined and connected into an integrated structure, during underwater pavement, the integrally-formed bionic water plant combined body is directly laid on the surface of a seabed suspension pipeline, the construction technology steps are greatly simplified, and the work efficiency is improved. The installing base pad is designed into a trapezoid or arc adapting to the appearance of the seabed suspension pipeline, seamless linkage of the installing base pad or seamless linkage with the seabed suspension pipeline can be directly achieved, connection is firmer, unfolding of bionic water plants forming a reel is not needed during underwater pavement, the pavement process is simplified, and the scouring preventing effect is improved.

Description

technical field [0001] The invention relates to the technical field of marine bionics, and more specifically relates to a seabed anti-scouring bionic system and its construction technology and application. Background technique [0002] The submarine oil (gas, water) pipeline is the lifeline of the development and utilization of marine oil and gas resources. Its safety directly affects the development of the offshore oil industry, the healthy growth of marine organisms and environmental protection. During the installation and oil and gas transportation of submarine pipelines, due to human marine activities such as fishing and ship traffic, as well as the harsh natural environment at sea, especially the erosion of submarine mudflows, it is inevitable that there will be some defects and damages that affect their safe operation, such as Suspension, bending, deformation and damage of the pipeline, cracks on the pipeline body, scratches and pits on the surface, etc. The existence...

Problems solved by technology

[0006] However, the existing biomimetic aquatic plant structure is a split type, and the underwater laying process is cumbersome. It is necessary to first put the biomimetic grass mat into the sea during advection, then hoist it with nylon ropes and tie it to both ends of the biomimetic grass reel, and slowly place it on the seabed Finally, the bionic grass is placed on the seabed and placed on one side of the pipeline. When laying, it is gradually spread from one side of the pipeline to the other side along the countercurrent direction, and anchored while unfolding according to the requirements; and the existing bionic aquatic plants are mostly square or rectangular as a whole. , the connection with the submarine suspended pipeline is not good, which makes the laying process more cumbersome, and the anti-scouring effect is also affected
