Sea area pipeline turning section connection construction method
The invention discloses a sea area pipeline turning section connection construction method, and relates to the technical field of sea pipeline laying engineering. The method comprises the following steps of digging a seabed groove according to a design axis of a sea area pipeline turning section; transporting a three-way pipe and welding equipment to a sinking site of the sea area pipeline turning section, and welding the three-way pipe to the top of the sea area pipeline turning section; preparing a steel floating box; fixing sea area pipeline linear sections on the two sides to a cross beam; filling the sea area pipeline linear sections on the front side and the rear side of the sea area pipeline turning section with gas to enable the sea area pipeline linear sections to emerge from the water surface, then dragging one end of each sea area pipeline linear section and one end of the sea area pipeline turning section to the steel floating box, and connecting a pipeline and the steel floating box into a whole; and controlling floating of a steel pipe by controlling the water injection amount in the steel floating box, performing sinking through a water injection method to enable the pipeline to be stably sunken into the pre-dug groove, and finally, sealing the three-way pipe through diving. The method is simple and reliable, a safe and stable operation environment is built on the sea, the welding quality is good, the construction period is short, and the construction cost is low.
一种海域管道转弯段连接施工方法，涉及海上管道铺设工程技术领域，其步骤如下，按照海域管道转弯段的设计轴线挖出海底沟槽；将三通管和焊接设备运输至海域管道转弯段的下沉地点，将三通管焊接至海域管道转弯段的顶部；制备钢浮箱；两侧的海域管道直线段固定在横梁上；向海域管道转弯段前后两侧的海域管道直线段中充入气体，使之浮出水面，然后将海域管道直线段的一端和海域管道转弯段的一端分别拖到钢浮箱上，将管道和钢浮箱连为一体；通过控制钢浮箱内的注水量控制钢管上浮，采用注水法下沉，使管道稳定下沉至预先挖好的沟槽中时最后，潜水将三通管密封。本发明简单可靠，在海上营造安全稳定的作业环境，焊接质量好，施工周期短，施工成本低。
