The invention relates to a method for installing a structure hoisted in a double-rope mode. The method comprises the steps that S1, the structure is connected to a crane lifting hook of a main crane; S2, the main crane lowers the structure to a first water depth; S3, a traction device is connected with the crane lifting hook, and a horizontal traction force is provided for the crane lifting hook; and S4, the main crane continues to lower the structure to an installation water depth; and S5, the structure is installed at a target position. According to the method, the traction device provides the horizontal traction force for the crane lifting hook which causes the torsion of a lifting rope of the main crane, and applies an additional anti-torsion moment to the crane lifting hook, so that the double-rope twisting caused by the rotation of the crane lifting hook is prevented.
本发明涉及一种双绳模式吊装的结构物安装方法,包括:S1、将所述结构物连接在主吊机的吊机吊钩上;S2、所述主吊机下放所述结构物至第一水深;S3、将牵引装置与所述吊机吊钩连接,为所述吊机吊钩提供一水平牵引力;S4、所述主吊机继续下放所述结构物至安装水深;S5、将所述结构物安装在目标位置。本发明通过牵引装置为引起主吊机吊绳扭转的吊机吊钩提供一水平牵引力,对吊机吊钩施加外加的抗扭力矩,从而防止因吊机吊钩旋转引起的双绳打扭。
