Sea-crossing pipe sinking construction process
The invention discloses a cross-sea-area pipe sinking construction process. The cross-sea-area pipe sinking construction process specifically comprises the following steps that S1, a groove is excavated; s2, gravel backfilling and leveling are conducted, wherein gravel backfilling and leveling construction can be conducted after the trench acceptance check is completed; s3, pipeline floating transportation and pipeline butt joint; s4, an integral pipeline sinking scheme; s5, testing air pressure and water pressure of the pipeline; s6, backfilling and mold bag concrete construction; according to the cross-sea-area pipe sinking construction technology, grab bucket type dredging equipment high in adaptability is selected, the underwater excavation soil layer depth of a pipeline groove is large, the side slope is large, the distance is long, the combined excavation depth is large, and the cross-sea-area pipe sinking construction technology is suitable for cross-sea-area construction.
本发明公开了一种跨海域的沉管施工工艺，具体包括以下步骤：S1：沟槽开挖；S2：碎石回填找平：沟槽验收完毕后即可进行碎石回填找平施工；S3：管道浮运和管道对接；S4：整体管道沉放方案；S5：管道气压、水压试验；S6：回填及模袋砼施工；本发明公开的跨海域的沉管施工工艺选择适应性强的抓斗式挖泥设备，管道沟槽水下开挖土层深度大、边坡大、距离长、该组合开挖深度大，适合跨海域的施工。
