Problems solved by technology

[0003] The suspension bridge structure can give full play to the characteristics of high tensile strength of high-strength cables. The vertical bearing capacity of the super-long-span canyon pedestrian suspension bridge is not a big problem. However, the canyon scenic pedestrian suspension bridge is usually a super-long-span narrow bridge with a large aspect ratio With the increase of the span of the pedestrian suspension bridge in the canyon scenic area, the problem of its wind resistance stability is becoming more and more prominent
[0004] Most of the existing pedestrian landscape suspension bridges in canyon scenic spots are still designed according to the traditional design concept of super long-span highway suspension bridges. The design of pedestrian landscape suspension bridges in canyon scenic spots lacks creativity. Unsatisfactory effect

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 ...

Abstract

Aiming at the two requirements of aesthetics and wind resistance stability of a super-large-span pedestrian landscape suspension bridge in a canyon scenic area, a traditional pedestrian landscape suspension bridge is improved, and two technical improvement measures of an egg arched bridge tower and hyperbolic paraboloid carbon fiber space cables are provided. The egg arched bridge tower is composed of a parabolic segment tower top, a left elliptic arc segment tower column and a right elliptic arc segment tower column, the egg arched bridge tower is quite harmoniously matched with a canyon peak in a scenic area and a suspension cable curve in shape, and the humanistic connotation of the scenic area can be improved. The parallel steel wire cable, the hyperbolic paraboloid carbon fiber space cable and the lower wind-resistant cable are used in a mixed mode, work cooperatively and have complementary advantages, the parallel steel wire cable bears vertical loads, and the hyperbolic paraboloid carbon fiber space cable and the lower wind-resistant cable work in a combined mode, so that the torsional rigidity and lateral rigidity can be improved; and the wind-resistant stability can be greatly improved. Stainless steel wire meshes are laid on the hyperbolic paraboloid space cables, vine plants are planted, sunlight is shielded, and the landscape effect is improved.

Description

technical field [0001] The invention belongs to the field of civil engineering, and relates to a construction technology of a pedestrian suspension bridge, in particular to a canyon pedestrian landscape suspension bridge with a carbon fiber space cable net and a construction method thereof. Background technique [0002] With the rise of tourism, the number of pedestrian suspension bridges in canyon scenic spots is increasing day by day. The magnificent pedestrian suspension bridges in canyon scenic spots have enriched the cultural connotation of canyon scenic spots and become a beautiful scenery in tourist areas. [0003] The suspension bridge structure can give full play to the characteristics of high tensile strength of high-strength cables. The vertical bearing capacity of the super-long-span canyon pedestrian suspension bridge is not a big problem. However, the canyon scenic pedestrian suspension bridge is usually a super-long-span narrow bridge with a large aspect ratio ...
