Problems solved by technology

[0003] The pedestrian landscape glass deck suspension bridge in the canyon scenic area is a characteristic bridge in the canyon scenic area. However, in recent years, there have been many tourists crowded on the pedestrian landscape glass deck suspension bridge, resulting in dangerous situations. The use safety of the pedestrian suspension bridge in the canyon scenic area has attracted attention from all walks of life.
[0004] The suspension safety net scheme of the pedestrian landscape glass deck suspension bridge in the canyon scenic area can increase the safety of the traditional pedestrian landscape suspension bridge, but it seriously damages the aesthetics of the pedestrian suspension bridge in the canyon scenic area. How to coordinate the aesthetics and The problem of safety in use is an urgent problem for bridge designers to solve

Embodiment 1

[0050] A long-span flat-drawn cylindrical mesh pedestrian landscape suspension bridge of the present invention comprises a suspension bridge tower 1, a cylindrical mesh space cable system 2, an anchorage 3, a bridge deck system 4 and a spiral vine grass plant 5, and its characteristics That is: the suspension bridge tower 1 is composed of a curved double-leg pier column 11 and a giant oval steel annular tower cap 12, and the giant oval steel annular tower cap 12 is fixed on the curved double-limb pier column 11; the mesh space The cable system 2 is composed of a single-leaf hyperboloid space cable net 21, an elliptical rigid stiffening ring 22, a double helix steel wire screen bar 23 and a suspension bridge back cable 24, and the single-leaf hyperboloid space cable net 21 is a drooping single-leaf hyperboloid cylinder Mesh configuration, the single-leaf hyperboloid space cable net 21 is anchored on the giant elliptical steel annular tower cap 12, and inside the single-leaf hype...

Embodiment 2

[0053] A construction method of a large-span flat-drawn tube mesh pedestrian landscape suspension bridge of the present invention comprises the following steps:

[0054] Step 1: According to the geological topography and landform requirements of the canyon scenic area, select the bridge site for the pedestrian landscape suspension bridge, construct the anchorage 3, construct the curved double-leg pier column 11, install the giant oval steel ring tower cap 12, and form a suspension bridge Tower 1;

[0055] Step 2: install the suspension bridge back stay cable 24, pull the steel wire cable across the river, the multi-strand steel wire cables intersect in space to form a single-leaf hyperboloid space cable net 21, and the single-leaf hyperboloid space cable net 21 is anchored to the giant elliptical steel annular tower cap 12 On top of that, inside the single-leaf hyperboloid space cable net 21, install multiple elliptical rigid stiffening rings 22, outside the single-leaf hyperb...

Embodiment 3

[0060] A pedestrian landscape glass suspension bridge on the Yarlung Zangbo River in Tibet, with a main span of 200m. In order to meet the landscape and use safety requirements of the canyon scenic spot, and to inherit the characteristics of the Medog rattan bridge in Tibet, a large-span flat-drawn tube mesh pedestrian landscape is adopted. Structural scheme of suspension bridge

[0061] The tower of the suspension bridge is composed of curved double-leg pier columns and giant oval steel ring-shaped tower caps, implying that the giant holds up the sun. The bridge tower adopts a pile foundation, and the highest point of the bridge tower is 25 meters. M×1.4m concrete-filled steel tube columns, two connecting beams are set between the curved double-leg pier columns, and the giant elliptical steel ring tower cap is a vertical ellipse shape, the ellipse height is 10 meters, the ellipse width is 8 meters, and the ellipse steel ring The tower cap adopts a 1.0m x 1.0m steel tube concr...

Abstract

The invention relates to a large-span horizontal pulling type cylindrical net-shaped pedestrian landscape suspension bridge and a construction method thereof. A horizontal pulling type pedestrian suspension bridge in a canyon scenic area is reformed by referring to a Tibet rattan net bridge, heavy concentrated cables are changed into dispersed single-blade double-curved-surface barrel net-shaped space cables, a small number of oval rigid stiffening rings are arranged in a barrel net, double-spiral steel wire stirrups in the positive direction and the negative direction are wound around the outer portion of the barrel net, and therefore, the large-span horizontal pulling type cylindrical net-shaped pedestrian landscape suspension bridge is formed. The single-blade double-curved-surface cylinder net-shaped space cables, the oval rigid stiffening rings and the double-helix steel wire stirrups work cooperatively, the torsional rigidity and lateral rigidity of the pedestrian suspension bridge are improved, and the pedestrian suspension bridge has good wind-resistant stability. According to the bridge tower anchoring barrel net-shaped space cable with the curved double-limb pier column and the huge oval steel ring tower cap, the weight of a single-strand cable is reduced through the scattered barrel net-shaped space steel wire cable, and construction is convenient. A transparent glass bridge deck is embedded in a bridge deck truss, cirrus grass is wound on the cylinder net-shaped space cable in a double-spiral mode, sunlight is shielded, ecological and environment-friendly effects are achieved, the appearance is attractive, tourists walk in the cylinder net-shaped suspension bridge, and personal safety can be guaranteed.

Description

technical field [0001] The invention belongs to the field of civil engineering, and relates to a pedestrian landscape suspension bridge, in particular to a large-span flat-drawn tubular mesh pedestrian landscape suspension bridge 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 in order to make the tourist traffic more convenient in canyon scenic spots, and the aesthetic and safety requirements of pedestrian suspension bridges in canyon scenic spots are getting higher and higher. [0003] The pedestrian landscape glass deck suspension bridge in the canyon scenic area is a characteristic bridge in the canyon scenic area. However, in recent years, many tourists have been crowded on the pedestrian landscape glass deck suspension bridge, which has caused dangerous situations. The use safety of the pedestrian suspension bridge in the canyon scenic a...
