Anti-scouring and silt-falling-promoting protection device for submarine pipeline
An anti-scouring and silt-falling-promoting protection device for a submarine pipeline comprises a pile foundation and a submarine pipeline, and a flow guide transmission structure is installed on the pile foundation. The flow guide transmission structure comprises a plurality of steel trusses, a plurality of rigid flow guide plates and a bottom plate. The structure is characterized in that the bottom plate is installed on the pile foundation, the multiple steel trusses are installed on the lower wall face of the bottom plate, and the multiple rigid flow guide plates are installed on the upper wall face of the bottom plate; the invention relates to the technical field of submarine pipeline scouring protection, and has the beneficial effects that through a flow guide transmission structure, the problems that the surrounding of a pipeline is covered with a riprap layer and a cushion is arranged to promote siltation, the method is easy to construct and has a certain protection effect, but the influence on a flow field is unpredictable due to the irregularity of riprap, and the construction cost is low are solved; in the prior art, the phenomenon of secondary scouring possibly occurs after a period of time, flexible protection means such as artificial grass and bionic seaweed are mostly adopted, but the problems that the effect is easily lost and damage occurs when the means are used for high-speed water flow are solved.
海底管道防冲刷促落淤防护装置，包括桩基以及海管，所述桩基上安装有导流传动结构；所述导流传动结构包括：若干钢桁架、若干刚性导流板以及底板；其特征在于，所述底板安装在所述桩基上，所述若干钢桁架安装在所述底板下壁面上，所述若干刚性导流板安装在所述底板上壁面上；本发明涉及海底管道冲刷防护技术领域，本案的有益效果为：通过导流传动结构，解决了通常在管线周围覆盖抛石层、排垫促淤，这类方法易于施工，有一定的防护效果，但由于抛石本身的不规则，对流场的影响不可预知，也有可能在一段时间后出现二次冲刷的现象，大多采用人工草、仿生海藻等柔性防护手段，但此类手段面对高速的水流，极易失去效果，发生破坏等问题。
