The invention discloses a self-rescue method for salvaging a continuous wall grab bucket, which comprises the following steps: step 1, after a grab bucket steel wire rope of continuous wall equipment is broken and the grab bucket falls into a groove section, cutting off a curled part of a broken end of a main winch steel wire rope of the grab bucket equipment to enable the residual main winch steel wire rope to be vertical without bending, and connecting the main winch steel wire rope with a lifting hook; 2, the depth of the grab bucket hoisted into the groove is measured, and a lifting hook is lowered from the side face of the grab bucket to the wall of the groove through a main winch steel wire rope; 3, after the lifting hook reaches a lifting position, rotating a main winch steel wire rope on the ground to enable the lifting hook to be hooked in a notch in the side face of the grab bucket; and 4, the grab bucket is lifted through the main winch steel wire rope, and the bucket head of the grab bucket is repeatedly opened and closed in the lifting period till the grab bucket is lifted to the ground to extend out of the head. According to the grab bucket, the steel wire rope is matched with the lifting hook, grab bucket fishing is carried out, cyclic utilization can be achieved, environment friendliness is achieved, the cost of all links of grab bucket fishing is reduced, and the construction cost is reduced.

    本发明公开了一种打捞连续墙抓斗自救方法,包括以下步骤:步骤1:在连续墙设备抓斗钢丝绳断裂,抓斗掉入槽段内后,切除抓斗设备主卷扬钢丝绳断裂端卷曲部分,使剩余主卷扬钢丝绳垂直无弯曲,将主卷扬钢丝绳与吊钩连接;步骤2:测量抓斗吊入槽内的深度,通过主卷扬钢丝绳将吊钩从抓斗侧面贴槽壁进行下放;步骤3:在吊钩达到起吊位置后,在地面旋转主卷扬钢丝绳,使吊钩勾在抓斗侧面的槽口内;步骤4:通过主卷扬钢丝绳对抓斗进行提升,在上提期间反复开关抓斗斗头,直到将抓斗提升至地面出头。本申请通过自身设备钢丝绳与吊钩配合,进行抓斗打捞,可循环利用,绿色环保,减少了打捞抓斗各个环节的费用,降低了施工成本。
