Embodiment 1
[0039] Such as Figure 1-2 , 7, shown in 10, a kind of suspension bridge main cable erection method of both sides tunnel type anchorage, comprises the following steps:
[0040] 1) Install the cable laying equipment 2 behind the anchorage gantry 1 on bank A, install the main cable traction equipment 4 between the anchorage gantry 1 on bank A and the front anchor surface 3 on bank B, install the main cable traction equipment 4 between the anchorage gantry 1 and Install traction equipment 5 and hoisting equipment 6 between the cable-laying equipment 2, install anchor chamber traction equipment 8 in the anchor room 7 in front of bank A and anchor room 26 in front of bank B, and install traction equipment 8 in the anchor room 7 in front of bank A and in front of bank B Anchor room hoisting equipment 9 is installed in the anchor room 26;
[0041] 2) The anchor head 10 of the main cable is connected to the traction device 5, and the anchor head 10 of the main cable is pulled to the ...
Embodiment 2
[0048] On the basis of Example 1, such as Figure 5-6 As shown, further, the main cable pulling device 4 adopts a circular pulling device, and the working range of the main cable pulling device 4 is that the anchorage gantry 1 on bank A is pulled to the front anchor surface 3 on bank B.
[0049] Such as Figure 3-4 As shown, further, the traction device 5 adopts a circular traction device, and the working range of the traction device 5 is from the cable-laying device 2 to the anchorage gantry 1 on the bank A.
[0050] Such as Figure 8-9 As shown, further, the traction equipment 8 in the anchor chamber adopts circular traction equipment, and the working range of the traction equipment 8 in the anchor chamber is from the anchorage gantry 1 on bank A to the anchor surface 12 in front of bank A.
[0051] Main cable traction equipment 4, traction equipment 5 and anchor chamber traction equipment 8 all adopt circular traction equipment, which has less traction equipment, saves ma...
