Combined muddy barrier

The utility model relates to the technical field of environment-friendly dredging, and discloses a combined muddy barrier which comprises an anti-fouling curtain and a bubble curtain generator, the bubble curtain generator is divided into an underwater part and an ashore part, the underwater part and the anti-fouling curtain define a closed area for dredging construction, the ashore part is connected with an air compression device, and the air compression device is connected with the bubble curtain generator. A muddy barrier is formed by the antifouling curtain and the bubble curtain generator, the requirement that a ship needs to enter and exit a dredging engineering area is met, and meanwhile diffusion pollution of silt particles is effectively prevented through reasonable matching of the bubble curtain generator and the antifouling curtain. 本实用新型涉及环保疏浚技术领域，公开了一种组合式拦浑屏障，包括：防污帘与气泡幕发生器，气泡幕发生器分为水下部分与岸上部分，水下部分与防污帘围成用于疏浚施工的封闭区域，岸上部分与空气压缩装置相接，通过防污帘与气泡幕发生器组成的拦浑屏障，满足了船舶需要进出疏浚工程区域的需求，同时气泡幕发送器与防污帘的合理搭配有效防止了泥沙颗粒的扩散污染。
