Abstract: The present invention provides an improved pipeline burying apparatus that uses specially configured jetting nozzles that intake sea water surrounding the nozzle. The apparatus provides a frame supporting spaced apart left and right inclined pipe sections that are configured to be placed on opposing sides of the pipeline to be buried. Each inclined pipe section is fitted with a plurality of jetting nozzles that are positioned on one of the inclined pipe sections, in vertically spaced apart positions and in horizontally spaced apart positions. At least some of said jetting nozzles include a nozzle body having an outer surface and a main, central longitudinal fluid flow channel with a central channel axis. A fluid inlet end portion of the nozzle body has an externally threaded portion that enables connection to an internally threaded portion of a selected one of the inclined pipe sections. A discharge end portion of the nozzle body extends outwardly from an inclined pipe and the threaded portion. A plurality of lateral channels each intersect the main channel at an acute angle. In one embodiment, the main central longitudinal channel has an inlet section with an inlet section diameter, a discharge section having an outlet section diameter and a connecting section that is in between the inlet section and the outlet section.

Abstract translation: 本发明提供了一种改进的管道埋设装置，其使用特别配置的喷嘴来吸入围绕喷嘴的海水。 该装置提供支撑间隔开的左右倾斜管段的框架，所述倾斜管段被配置为放置在待埋设的管道的相对侧上。 每个倾斜管段装配有多个喷嘴，这些喷嘴位于其中一个倾斜管段上，位于竖直间隔位置和水平间隔位置。 至少一些所述喷射喷嘴包括具有外表面的喷嘴主体和具有中央通道轴线的主中央纵向流体流动通道。 喷嘴体的流体入口端部分具有外螺纹部分，该外螺纹部分能够连接到倾斜管部分中选定的一个的内螺纹部分。 喷嘴体的排出端部分从倾斜管和螺纹部分向外延伸。 多个横向通道均以锐角与主通道相交。 在一个实施例中，主中央纵向通道具有具有入口部分直径的入口部分，具有出口部分直径的排出部分和位于入口部分和出口部分之间的连接部分。
