Cable dismounting method and cable dismounting equipment for cable-stayed bridge without bracket dismounting
The invention relates to the field of bridge body dismantling, in particular to a cable dismantling method for dismantling a cable-stayed bridge without a support, which comprises the following steps of: connecting a tool anchor ring with an upper end anchor head of a cable, and arranging a jack at the upper end of the cable; the jack tensions the inhaul cable until the anchor head is disengaged; a working anchor ring of the anchor head is cut off and removed; the tool anchor ring rotates to be separated from the anchor head, then the jack releases the inhaul cable till the jack reaches the stroke limit, the tool anchor ring is connected to the anchor head, then the jack is reset, and the operation is repeated for multiple times till the tension of the inhaul cable is low; a group of two-circle holes are formed in the surfaces of the upper end and the lower end of the inhaul cable, bolts are screwed into the two ends of the cable clamp and inserted into the holes in the surface of the inhaul cable, and then the cable clamp is fastened through the bolts and nuts to be tightly attached to the inhaul cable; pulling force for approaching the two cable clamps is applied to the two cable clamps through traction equipment until the tension of the inhaul cable between the two cable clamps is zero; and the inhaul cable between the two cable clamps is cut off, so that the safety is improved during cable disassembling operation.
本申请涉及桥体拆除的领域，涉及一种斜拉桥无支架拆除的拆索方法，将工具锚环和拉索的上端锚头进行连接，然后在拉索的上端处进行千斤顶的设置；千斤顶张拉拉索至锚头脱空；将锚头的工作锚环切断去除；工具锚环转动脱离于锚头，然后千斤顶将拉索放张，直至千斤顶达到行程极限后，工具锚环再连接于锚头，然后千斤顶复位，重复数次，直至拉索张力较低；在拉索上端和下端表面均成型一组两圈孔洞，索夹两端均旋入螺栓并插入至拉索表面孔洞，再将索夹使用螺栓搭配螺母进行紧固以紧贴拉索；使用牵引设备向两个索夹施加相靠近的拉力直至两个索夹之间的拉索张力为零；将两个索夹之间的拉索切断，使得拆索作业时安全性获得提升。
