黄河下游的机淤固堤工程,正在从险工堤段向平工堤段发展,现有的简易吸泥船能否适应需要,是决定机淤固堤能否继续向前发展的关键。文章叙述了山东黄河机淤固堤的发展过程和现状,分析了简易吸泥船远距离输沙的可能性及其更新、改造的必要性。分析认为,山东黄河利用简易吸泥船进行堤防加固,可以满足由险工向平工堤段发展的需要。文章提出了确定经济、合理的机淤加固堤段的三个条件,对推广和发展绞吸式挖泥船也提出了积极的建议。
The project of machine-made silt embankment in the lower Yellow River is developing from the section of embankment to the section of embankment, and whether the existing simple sucker can meet the need is the key to decide whether the silt embankment can continue to move forward. The paper describes the development process and current situation of silt embankment in the Yellow River in Shandong Province, and analyzes the possibility of long-distance sediment transport by simple suction dredgers and the necessity of updating and transforming them. Analysis, Shandong Yellow River using simple suction dikes for embankment reinforcement, can meet the needs of the workers to the flat section of the dike development. The article puts forward three conditions for determining the economic and reasonable mechanical silt reinforcement of embankments, and puts forward some positive suggestions for the promotion and development of the cutter suction dredger.
