Embodiment Construction

[0009] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0010] A method of using bionic aquatic plants to cover suspended submarine pipelines. Firstly, sand and stone are used to backfill the scoured grooves in the lower part of the submarine pipeline 4, and a bionic anti-scouring protection system is installed on the backfill layer 5 after filling.

[0011] The bionic anti-scouring protection system includes bionic seagrass 1 made of new polymer materials that are resistant to seawater immersion and long-term erosion, bionic seaweed 1 installation base pad 3, specially designed seabed anchoring devices, and special underwater hydraulic tools. The installation method is to first fix the base pad 3 and the anchoring device on the backfill layer 5, and then fix the anti-biosis seaweed 1 on the base pad 3, when the seabed water flows through the bionic seaweed 1, it is subjected to the flexible and viscous damp...

Abstract

The invention provides a method for using bionic aquatic plants to cover the suspended submarine pipeline. First, sand and gravel are used to backfill the scoured groove at the bottom of the submarine pipeline, and after filling, a bionic anti-scour protection system is installed on the backfill layer; Flexible installation and construction, in line with environmental protection requirements.

Description

technical field [0001] The invention relates to an underwater structure and a pile foundation, in particular to a method for fixing a submarine pipeline. Background technique [0002] In the design of submarine pipelines, it is required to be buried 1.5 meters below the mud surface, without considering the adverse effects of suspension. Therefore, in the stress calculation of submarine pipelines, the strength, fatigue and And other unfavorable factors are extremely dangerous. Because the submarine pipelines are all pressure pipelines, the internal pressure of the crude oil pipeline reaches 2.5~5Mpa, and the crude oil in the pipeline has 15 0 C~80 0 The temperature difference of C changes, and the internal pressure of the water injection pipeline reaches 16Mpa~20MPa. Under the action of temperature and pressure, the pipeline bears a considerable internal force, and these forces are also superimposed with the earthquake, external water pressure, and overlying soil pressure,...
