The antifouling screen comprises a main self-floating body, a long-distance woven belt, an anchor pulling rope, a fixing anchor, a side self-floating body, a cloth winding cylinder, curtain cloth and a hanging falling body, the peripheral side of the main self-floating body is wound with an outer woven belt, and the outer woven belt comprises a plurality of longitudinal woven parts and a plurality of transverse woven parts. In the antifouling process, the ends of the two pieces of curtain cloth are supported above the water surface by the side self-floating bodies and are in positioning connection with the side self-floating bodies through the buckling parts, and when the curtain cloth needs to be detached for maintenance, the curtain cloth facing the flowing direction is directly hung on the water surface through a hook of a hoisting device on a construction ship, so that the curtain cloth is prevented from being damaged. The curtain cloth can be conveniently taken out from the upper portion of the side self-floating body by pulling the hoisting hooks upwards, maintenance of the curtain cloth is facilitated, after the curtain cloth is taken out, the curtain cloth opposite to the flowing direction immediately plays a role in shielding suspended matter, the normal antifouling effect of the antifouling screen cannot be affected when the curtain cloth is maintained, and use is convenient.
本发明提出了一种用于海提外航道开挖的防污屏及其施工方法,包括主自浮体、长距编织带、拉锚绳、固定锚、侧自浮体、饶布筒、帘布和悬坠体,其中,主自浮体的周侧缠绕有外编织带,所述外编织带包括多个纵编织部和多个横编织部。防污过程中,两个帘布的端部均被侧自浮体承托在水面上方,并通过扣接部件与侧自浮体定位连接,在需要拆离帘布进行维护时,将施工船上吊装装置的挂钩直接在水面上挂起朝向流动方向的帘布,上拉吊装挂钩即可便捷将帘布从侧自浮体的上方取出,便于对帘布进行维护,且在将帘布取出后,背向流动方向的帘布即刻起到遮挡悬浮物的作用,使在对帘布进行维护时可以不影响防污屏的正常防污效果,方便使用。
