悬索桥施工安全控制要点(国外英文资料) The diameter and the circumference of the main cable are measured separately using the special measuring device. 6.8.8, the main cable thread construction safety points: 1, the tie wire order The threads are interlaced and then interlaced. The edge span is carried out by the anchor to the sotta direction, which is carried out across the direction of the sotta. 2, main cable tie wire 1) the silk wheel is wrapped around the wire S shaped steel wire according to the interval between each cable clip precise dosage of steel wire and to supply volume, through the special wire machine in front of the shoulders with a certain tension will s-shaped wire coil turns around to store wire wheel, for main cable clip interval corresponding tie wire. Be aware of the safety in the process. 2) the spinning machine is in operation Install the thread machine on the top side of the tower, and install maintenance and debugging. In each speed reducer, the gearbox is filled with lubricating oil, and all other sports and other sports are required to add lubricating oil or grease. Perform the operation of the empty machine according to the requirement, and do all the preparation before the test. Adjust the turning of the thread ring and the forward motion of the current to the frequency converter, make the tooth ring each turn a circle (that is, the thread 1 ring) while along the frame to walk 9mm. 3) the wrapping test The wire thread test is carried out, the main test of the thread machine performance and welding strength, and confirm the following criteria: There is no gap between the wires. No overlapping winding, cross entanglement; The surface is smooth; The welding strength of the solder is to ensure that the shear strength is above the tension wire. Safety issues should be noted during the construction of the main cable. By strapping machine for main cable tie silk, major construction technology include: cable clip before the start of artificial extrusion tie wire
