The invention relates to the technical field of HDPE pipeline butt joint, in particular to an HDPE pipeline underwater flange butt joint system and a butt joint method.The HDPE pipeline underwater flange butt joint system comprises a crane ship and a plurality of air sacs, the air sacs are bound to an installed HDPE pipeline and a to-be-installed HDPE pipeline, the crane ship comprises a first winch, a second winch and a crane, and the crane ship comprises a first winch, a second winch and a second winch. First cables of the first winch and the second winch are connected with the to-be-mounted HDPE pipeline, and the crane is connected with the to-be-mounted HDPE pipeline through a second cable; the first winch and the second winch are used for adjusting the horizontal position of the to-be-installed HDPE pipeline, and the crane is used for adjusting the elevation of the to-be-installed HDPE pipeline. According to the underwater flange butt joint system, the defects of a traditional underwater HDPE pipeline butt joint technology are overcome, the precision, efficiency and safety of butt joint of large-diameter and overweight HDPE pipeline underwater flanges are remarkably improved, high applicability and economical efficiency are achieved, and a reliable technical solution is provided for HDPE pipeline installation in ocean engineering.

    本发明涉及HDPE管道对接技术领域,特别涉及一种HDPE管道水下法兰对接系统、对接方法,其中HDPE管道水下法兰对接系统包括起重船和若干气囊,气囊绑扎于已安装HDPE管道和待安装HDPE管道,起重船包括第一卷扬机、第二卷扬机以及吊机,第一卷扬机和第二卷扬机的第一线缆均与待安装HDPE管道连接,吊机通过第二线缆与待安装HDPE管道连接;第一卷扬机和第二卷扬机用于调整待安装HDPE管道的水平位置,吊机用于调整待安装HDPE管道的标高。该水下法兰对接系统不仅克服了传统水下HDPE管道对接技术的诸多不足,显著提高了大直径、超重量HDPE管道水下法兰对接的精度、效率和安全性,还具有较强的适用性和经济性,为海洋工程中的HDPE管道安装提供了一种可靠的技术解决方案。
