Dredging engineering bubble type antifouling curtain construction method and antifouling curtain
The invention discloses a dredging engineering bubble type anti-fouling curtain construction method and an anti-fouling curtain. The construction method comprises the following steps of construction preparation, bubble curtain purchase and air compressor type selection and purchase. Assembling and testing bubble curtain equipment on the land; shipping and transporting to a traffic ship; judging how to arrange bubble curtain equipment according to the water flow velocity; two mathematical models are constructed to carry out numerical simulation research on the antifouling mechanism of the bubble curtain, and the bubble distribution of the bubble curtain, the bubble curtain formation, the flow field distribution, the dredged matter concentration distribution and the motion trail of suspended matter particles are quantitatively researched. According to the method, seven key parameters influencing the antifouling effect of the bubble curtain, such as the water flow speed, the wave height, the particle diameter, the orifice diameter, the ventilatory capacity, the curtain arrangement mode and the distance between the two bubble curtains, are determined, the antifouling blocking effect and the failure condition of the bubble curtain are summarized, then model selection and arrangement of the bubble curtain are guided, and the problem of failure of the bubble curtain is avoided.
本发明公开了一种疏浚工程气泡式防污帘施工方法及防污帘，该施工方法包括以下步骤：施工准备、气泡帘购买以及空压机选型及购买；气泡帘设备陆地组装和测试；装船运输至交通船；根据水流流速，判定如何布置气泡帘设备；通过构建两种数学模型对气泡帘的防污机理开展数值模拟仿真研究，定量研究了气泡帘的气泡分布、气泡帘形成、流场分布、疏浚物浓度分布和悬浮物颗粒的运动轨迹，确定了水流速度、波高、颗粒直径、孔口直径、通气量、布帘方式、双气泡帘间距等七个影响气泡帘防污效果的关键参数，总结出气泡帘防污阻挡效果和失效情况，进而对气泡帘的选型布置进行指导，避免出现气泡帘失效的问题。
