| Abstract: | In order to avoid the influence of the rebuilding of power transmission line on normal op?eration of spanning objects, in the process of constructing power transmission tower, adopts a construc?tion method of using the internal suspension assistant setting appliance, gradually raising middlephase power line, keeping the line without falling, rebuilds the crossover section of 330 kV powertransmission line from Daba to Guyuan spanning the thruway from Fuzhou to Yinchuan. The applica?tion result shows that the construction method of using two aluminium alloy thin assistant setting appli?ances without falling power line replacing ZM tower have the characteristics of operation simple, safe?ty and trustiness, greatly saving the cost, which can spread widely in similar project. |
