The invention provides an underground diaphragm wall reinforcement cage segmental hoisting connection method which comprises the following steps: S1, segmenting a diaphragm wall reinforcement cage, S2, processing main reinforcements of the diaphragm wall reinforcement cage, and respectively processing the main reinforcements at joints into wire ends and standard wire ends; s3, before the continuous wall reinforcement cage is hoisted, the whole length of the reinforcement mechanical connection sleeve is screwed into the thread adding thread end of the reinforcement cage which is hoisted firstly; s4, the firstly-hoisted reinforcement cage is suspended on the underground diaphragm wall guide wall through a cross arm; the hoisting method comprises the following steps of (S1) hoisting a reinforcement cage, (S2) hoisting the reinforcement cage, (S5) suspending a later hoisting reinforcement cage above the first hoisting reinforcement cage, (S6) upwards screwing a reinforcement mechanical connecting sleeve, and (S7) taking down a cross arm, continuing to lower the reinforcement cage of the diaphragm wall, and repeating the steps (S4) to (S6) until the hoisting of the reinforcement cage of the underground diaphragm wall is completed. The reinforcing steel bar mechanical connecting sleeve is upwards butted with the standard screw head to complete the butting of the reinforcing steel bar cage, so that the butting difficulty of the reinforcing steel bar mechanical connecting sleeve is reduced, and the stability of a joint part is ensured.

    本发明提供一种地下连续墙钢筋笼分节吊装连接方法,包括以下步骤:步骤S1,对连续墙钢筋笼进行分节,步骤S2,加工连续墙钢筋笼的主筋,接头处主筋分别加工为加长丝头和标准丝头;步骤S3,连续墙钢筋笼吊装前,将钢筋机械连接套筒全长拧入先吊装钢筋笼的加长丝头上;步骤S4,通过横担将先吊装钢筋笼悬吊在地下连续墙导墙上;步骤S5,将后吊装钢筋笼悬吊在先吊装钢筋笼上方,步骤S6,将钢筋机械连接套筒向上旋拧,步骤S7,取下横担,继续下放连续墙钢筋笼,重复步骤S4‑S6,直至完成地下连续墙钢筋笼的吊装。采用钢筋机械连接套筒向上对接标准丝头以此完成钢筋笼的对接,以此降低钢筋机械连接套筒的对接难度,保证接头部分的稳定性。
