Embodiment Construction
[0022] The following is an implementation plan for building a sightseeing bridge in a wildlife park. The bridge is a cable-stayed bridge, and a main tower is connected to the main beam through 12 steel main beam cables S1, S2, ..., S12. Such as figure 1 As shown, the anchoring end 3 of each main girder cable 1 passes through the pre-embedded cable casing 2 in the main girder 5 and is anchored in the concave tooth-shaped space 4 at the bottom of the main girder. The angle of inclination formed between the anchorage end of each main girder cable and the bottom surface of the main girder is different, and it is required that the cable casing 2 embedded in the edge of the tooth-shaped space 4 is consistent with the inclination angle of the stay cable 1 .
[0023] The following is the positioning method of the cable casing:
[0024] 1. According to the cable positioning coordinate system given on the drawing and the positioning parameter table of the cable, the geometric dimension...
