Large-scale drag suction ship bow mud blowing and conveying bifurcated pipe head loading and barge system and construction method

Abstract

The invention discloses a large-scale drag suction ship bow mud blowing and conveying bifurcated pipe head loading and barge system and a construction method. The large-scale drag suction ship bow mud blowing and conveying bifurcated pipe head loading and barge system comprises a mud conveying pipeline, wherein one side of the mud conveying pipeline is connected with a mud supply system, and the other side of the mud conveying pipeline is connected with the inflow end of a four-way reducing pipe; the outflow end of the four-way reducing pipe is connected with three mud conveying branches; the three mud conveying branches are connected with valves; the valves are connected through a wireless controller; the tail ends of the mud conveying branches are connected with the inflow end of a three-way adapter pipe; the outflow end of the three-way adapter pipe is connected with loading and barge branch pipes; a plurality of outflow pipe nozzles are arranged on the sides, close to a mud conveying barge, of the loading and barge branch pipes; the outflow pipe nozzles are connected with mud blowing steel pipes; the other ends of the mud blowing steel pipes are connected with mud blowing rubber pipes; and three flat-plate barges are arranged in parallel and are fixed by connecting cables with cable columns, so that a bow blowing and loading and barge platform is assembled. According to the large-scale drag suction ship bow mud blowing and conveying bifurcated pipe head loading and barge system and the construction method, the three flat-plate barges are adopted as a bearing platform, so that the overall stability is good, the wind wave resistance is high, the loading and barge pipeline of the loading and barge system is simple in structure, and hoisting, mounting and dismounting are facilitated.

Description

technical field [0001] The invention relates to a barge loading system and construction method of a large-scale trailing suction ship's bow blowing mud diverging pipe head, and belongs to the technical field of dredging construction. Background technique [0002] During the dredging construction process of large self-propelled trailing suction ships in coastal waters, in order to effectively increase the valuable time of trailing suction dredging operations, the bow mud pump is usually used to blow and transport mud from the pipeline to quickly and efficiently unload the mud tank. dredged mud. However, the water depth in the near-coastal sea area is usually very shallow, which cannot meet the draft requirements of large dragging suction ships, which makes the distance from the shore of the dragging suction ships far away. Efficiency will also significantly increase the cost of dredging construction. At this time, the mud can be unloaded by dragging the bow of the suction s...
