采用固定式人字抱杆起吊电杆的正确方法是()。

A、选择抱杆高度:一般可取电杆重心高度加2~3m。或者根据吊点距离和上下长度、滑车组两滑轮碰头的距离适当增加裕度来考虑;

B、绑系侧拉绳:据杆坑中心距离,可取电杆高度的2倍;

C、选择滑车组:应根据水泥杆重量来确定。一般水泥杆质量为500~1000kg时,采用一、一滑车组牵引;水泥杆质量为1000~1500kg时,采用一、二滑车组牵引;水泥杆质为1500~2000kg可选用二、二滑车组牵引;

D、18m电杆单点起吊时,必须采取加绑措施来加强吊点处的抗弯强度。

E、如果土质较差时,抱杆脚需铺垫道木或垫木,以防止抱杆起吊受力后下沉。

F、起吊过程中要求缓慢均匀牵引。电杆离地0.5m左右时,应停止起吊,全面检查侧拉绳子受力情况以及地锚是否牢固。水泥杆竖立进坑时,特别应注意上下的侧拉绳受力情况,并要求缓慢松下牵引绳,切忌突然松放而冲击抱杆。
