Embodiment 1

[0040] Such as Figure 1-Figure 5 As shown, the construction scheme of the main tower suspension bridge applicable to wide and deep canyons of the present invention comprises the following construction steps:

[0041] Step 1: construction of the inclined shaft 1, after the construction of the main line of the tunnel at both ends of the canyon is completed, an inclined shaft 1 is opened on both sides of the tunnel entrance at both ends;

[0042] Step 2: install the anchoring body 24, and pour the anchoring body 24 in the inclined shaft 1 after the construction of the inclined shaft 1 is completed;

[0043] Step 3: install the main cable saddle 21, after the construction of the anchor body 24 is completed, install the main cable saddle 21 near the entrance of the tunnel in the inclined shaft 1;

[0044] Step 4: install the loose cable saddle 22, after the main cable saddle 21 is installed and fixed, install the loose cable saddle 22 behind the main cable saddle 21 along the inc...

Embodiment 2

[0050] Such as Figure 1-Figure 5 As shown, a suspension bridge without a main tower suitable for wide and deep canyons, its working principle is: by setting the main cable saddle 21, the stress direction of the main cable 3 is converted to the axial direction of the inclined shaft 1, and then the main cable saddle 21 22 disperse the main cable 3 into a plurality of cables 23 and then connect with the cable fixing device 25, then fix the main cable 3 in the mountain body through the cable fixing device 25 fixed in the anchor 24, and provide the suspension and fixing of the main girder 4 tension, thereby replacing the main tower of the suspension bridge to reduce construction difficulty and project cost. The combination of the inclined shaft 1 and the tunnel can provide a working space for the construction of the anchoring structure 2 .

[0051]The towerless suspension bridge includes an inclined shaft 1, an anchoring structure 2, a main cable 3, a main girder 4 and a sling 5,...

Abstract

The invention discloses a main-tower-free suspension bridge suitable for a wide and deep canyons and a construction scheme. The construction scheme comprises: performing inclined shaft construction; installing an anchoring body; installing a main cable saddle; installing a loose cable saddle; installing a cable fixing device; installing main cables; installing cables; and performing main beam and sling construction. The main-tower-free suspension bridge comprises an inclined shaft, an anchoring structure, a main cable, a main beam and slings, wherein the main beam is erected between canyons; the inclined shafts are arranged at two sides of the tunnel portal, and two inclined shafts are arranged at the tunnel portal at two ends; the anchoring device is combined with the inclined shaft and is fixed at the front end of the inclined shaft; the two main cables are connected with the corresponding anchoring structures at the two ends of the canyon correspondingly. One end of the sling is connected with the main cable and the other end is vertically connected with the girder. Mountains on the two banks of the canyon are fully utilized, anchoring structures are arranged in the mountains, the mountains are used for fixing main cables of the suspension bridge, so that arrangement of a main tower is avoided, the construction difficulty of the suspension bridge is further reduced, and meanwhile the construction cost of the suspension bridge is also reduced.

Description

technical field [0001] The invention relates to the field of road and bridge construction, in particular to a towerless suspension bridge suitable for wide and deep canyons and a construction scheme. Background technique [0002] The construction of national infrastructure of tunnels, mountain highways, railways, etc. are increasingly entering the western mountainous areas. Due to the complex terrain in the western mountainous area, there are more and more "mountain-canyon-mountain" situations, and the line must be crossed in the form of "tunnel-bridge-tunnel". Due to the strong mountains and steep canyons, they are often connected by bridges and tunnels. When the width of the canyon is not large, it is often possible to use conventional bridges to cross; the line is often controlled by the elevation, and the width of the steep canyon section is large, and it is difficult to use conventional bridges; cable-stayed bridges and suspension bridges are common forms of long-span ...
