Embodiment 1
[0041] A canyon pedestrian landscape suspension bridge with carbon fiber space cable net of the present invention comprises oval arch bridge tower 1, parallel steel wire cable system 2, anchorage 3, bridge deck system 4, hyperbolic paraboloid cable net system 5, anti-corrosion The wind cable system 6 and the vine grass sunshade roof 7 are characterized in that: the oval arch bridge tower 1 is composed of a parabolic section tower top 11 and two left and right elliptical arc section tower columns 12; the parallel steel wire cable system 2 is composed of parallel steel wire cable 21. Suspension bridge back cables 22 and vertical suspension cables 23 are composed of parallel steel wire cables 21 anchored between two egg-shaped arched bridge towers 1, and one end of suspension bridge back cables 22 is anchored on egg-shaped arched bridge towers 1. One end is anchored in the anchorage 3, one end of the vertical sling 23 is anchored to the parallel steel wire cable 21, and the other ...
Embodiment 2
[0047] A kind of canyon pedestrian landscape suspension bridge construction method with carbon fiber space cable net of the present invention comprises the following steps:
[0048] Step 1: According to the geological topography and landform conditions of the canyon scenic area, select the bridge site for the super-large-span pedestrian landscape suspension bridge, construct the bridge foundation, simmer and bend the steel pipes, weld and assemble the tower top 11 of the parabolic section and the tower column 12 of the elliptical arc section, and pour Concrete inside the tube to form egg-shaped arched bridge tower 1, and build anchorage 3 at the same time;
[0049] Step 2: Pull the left and right two strands of parallel steel wire cables 21 and hang them between the two oval arched bridge towers 1, anchor the suspension bridge back cable 22 in the foundation of the anchorage 3, install the vertical sling 23, and hoist the bridge deck system Stiffened beam lattice 41, forming p...
Embodiment 3
[0055] The super-long-span pedestrian landscape suspension bridge in a canyon scenic spot has a main span of 600m and a bridge deck width of 6m. In order to meet the requirements of landscape aesthetics and wind resistance stability in the canyon scenic spot, a canyon pedestrian landscape suspension bridge with carbon fiber space cable net is adopted Technical solutions.
[0056] The egg-shaped arched bridge tower is composed of a parabolic tower top and two elliptical arc-shaped tower columns on the left and right. The highest point of the bridge tower is 68 meters, and the widest part of the bridge tower is 50 meters. The width of the parabolic tower top is 40 meters. , with a sagittal height of 8 meters and a tower column height of 60 meters in the elliptical arc section. The egg-shaped arched bridge tower is made of circular steel pipes with a diameter of 4 meters. pile foundation.
[0057] The space cable system is composed of parallel steel wire cables and carbon fiber ...
