Embodiment Construction
[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.
[0036] figure 1 It is a schematic top view structural diagram of a pipeline protection device provided in an embodiment of the present application, see figure 1 , the protective device of the pipeline includes: an underground anti-scour wall 1, a revetment retaining wall 2 and an apron 3. The underground anti-scour wall 1 is buried in the river channel crossed by the target pipeline 4 to be protected, and is located downstream of the target pipeline 4. The length direction of the underground anti-scour wall 1 is perpendicular to the direction of the river channel. The revetment retaining wall 2 is connected, and the top surface of the underground anti-scour wall 1 is not lower than the riverbed surface of the river ...

The embodiment of the invention discloses a pipeline protection device, and belongs to the field of oil and gas long-distance pipelines. The pipeline protection device comprises an underground scour prevention wall, a bank protection retaining wall and an apron. The underground scour prevention wall is buried in a river channel penetrated by a target pipeline to be protected and located on the downstream of the target pipeline, the length direction of the underground scour prevention wall is perpendicular to the trend of the river channel, the end of the underground scour prevention wall is connected with the bank protection retaining wall, and the top face of the underground scour prevention wall is not lower than the riverbed face of the river channel. The length direction of the bank protection retaining wall is parallel to the trend of the river channel, the bank protection retaining wall is attached to the river bank of the river channel, and the top face of the bank protection retaining wall is not lower than the river bank. The apron is buried in the river channel and located on the downstream of the underground scour prevention wall, the side face of the apron is fixedly connected with the underground scour prevention wall, the end of the apron is connected with the bank protection retaining wall, and the top face of the apron is not higher than the top face of the underground scour prevention wall. According to the pipeline protection device provided by the embodiment of the invention, the upstream riverbed surface can be prevented from descending, and the burial depth of the target pipeline is ensured.
Description
technical field [0001] The embodiments of the present application relate to the field of long-distance oil and gas pipelines, and in particular to a pipeline protection device. Background technique [0002] Oil and natural gas are usually transported by pipeline, and with the continuous consumption of oil and natural gas energy, the scale of oil and gas pipeline network continues to expand, and the pipeline coverage area is also wider. However, my country's terrain is diverse and complex. When laying pipelines in mountainous areas, it is inevitable to cross rivers and other areas with complex geological conditions. For pipelines passing through mountainous rivers, mountainous rivers are prone to geological disasters such as mountain torrents, and mountain torrents increase the flow velocity and impact force of the water flow, resulting in greater scouring of the riverbed, causing the riverbed to drop, resulting in buried pipelines Insufficient, followed by accidents such as...
