The invention relates to the technical field of HDPE pipeline sinking, in particular to a sinking system and method for an HDPE pipeline, and the sinking system for the HDPE pipeline comprises a plurality of air bags, hanging belts, sacrifice ropes, first lengthening hanging belts and/or second lengthening hanging belts; the air bag is connected with the hanging belt through the sacrificial rope, and the hanging belt wraps the HDPE pipeline to be immersed. The first lengthening sling and/or the second lengthening sling are/is installed between the air bag and the sling, and the first lengthening sling and/or the second lengthening sling are/is used for lengthening the distance between the air bag and the sling. According to the sinking system, the first lengthening hanging belt and/or the second lengthening hanging belt are/is arranged between the air bag and the hanging belt, first-time sinking of the pipeline is achieved after the pipeline is filled with water, one-time sinking in place is not needed, the bending stress borne by the pipeline in the initial stage of sinking is effectively reduced, and the sinking efficiency is improved. And then the distance between the air bag and the lifting belt is prolonged by selecting the first lengthening lifting belt and/or the second lengthening lifting belt according to the depth of first-time sinking, so that the pipeline is more stably and accurately sunk.

    本发明涉及HDPE管道沉放技术领域,特别涉及一种用于HDPE管道的沉放系统、沉放方法,其中用于HDPE管道的沉放系统包括若干气囊、吊带、牺牲绳、第一增长吊带和/或第二增长吊带;气囊通过牺牲绳与吊带连接,吊带包缠待沉放HDPE管道;第一增长吊带和/或第二增长吊带安装于气囊与吊带之间,第一增长吊带和/或第二增长吊带用于延长气囊与吊带之间的距离。该沉放系统通过在气囊与吊带之间设置第一增长吊带和/或第二增长吊带,当管道灌水后实现管道的首次沉放,不必一次沉放到位,有效降低管道在沉放初期受到的弯折应力,然后根据首次沉放的深度选择使用第一增长吊带和/或第二增长吊带来延长气囊与吊带之间的距离,使管道更加平稳精确的沉放。
