Embodiment 1

[0030] Embodiment 1: as figure 1 and figure 2 As shown, a kind of anti-rockfall sunshade structure for tunnel bridge 4, including tensile structure 1, connector 2 and sunshade cloth 3;

[0031] Both ends of the tunnel bridge 4 are fixedly provided with a tension structure 1, and the two tension structures 1 are connected by a plurality of connectors 2, and the plurality of connectors 2 are arranged along the width direction of the tunnel bridge 4 , a plurality of the connecting parts 2 are covered with the sunshade cloth 3 .

[0032] In this embodiment, the inter-tunnel bridge 4 is a bridge between two tunnels, and the two ends of the inter-tunnel bridge 4 are fixed with a tension structure 1, and the tension structure 1 can be fixed above the tunnel entrance, or can be directly fixed on the At the foot of the mountain slope, two tensile structures 1 are connected by a plurality of connectors 2, and the plurality of connectors 2 are arranged along the width direction of the...

Embodiment 2

[0043] Embodiment 2: as image 3 As shown, the difference between this embodiment and Embodiment 1 is that the connector 2 is a steel arch structure, and the arch feet at both ends of the steel arch structure are respectively fixed at the two ends of the inter-tunnel bridge 4. A plurality of slings 7 are connected to the tensile structure 1 , one end of the sling 7 is connected to the tensile structure 1 , and the other end of the sling 7 is connected to the steel arch structure.

[0044] In this embodiment, when the connecting piece 2 adopts a steel arch structure, a plurality of steel arch structures are arranged along the width direction of the bridge between tunnels 4, and the sunshade cloth 3 is covered on the plurality of steel arch structures, so that the rockfall on the mountain body can be achieved. To achieve a good resistance effect, the tensile structure 1 is connected to the steel arch structure through the sling 7 to stabilize the steel arch structure. . Furthe...

Abstract

The invention provides an anti-rockfall and shading shed structure for an inter-tunnel bridge. The anti-rockfall and shading shed structure comprises a tension bearing structure, connecting pieces andshading cloth. The two ends of the inter-tunnel bridge are respectively and fixedly provided with a bearing and pulling structure, the two bearing and pulling structures are connected through the connecting pieces, the connecting pieces are arranged in the width direction of the inter-tunnel bridge, and the connecting pieces are covered with the sunshade cloth. By the adoption of the scheme, pulse force on falling rocks can be effectively unloaded, impact of the falling rocks on bridges between tunnels is prevented, the whole tunnel is light, convenient and fast to use, construction is easy,prefabrication and splicing are achieved, the construction period is shortened, the sunshade effect is achieved, the visual fall of a light and shade alternating area is reduced, and the safety performance is greatly improved.

Description

technical field [0001] The invention relates to the field of tunnel protection engineering, in particular to a rockfall-preventing and light-shielding shed structure for bridges between tunnels. Background technique [0002] Railways, highways and bridges are important infrastructures that the country needs to build when implementing the spatial planning strategy, and play an important role in the development of the national economy and people's livelihood. When the existing railway and highway pass through complex terrain, variable geological structure, surrounded by rivers, and mountainous areas with steep canyons, there will inevitably be situations where bridges and tunnels are connected and the tunnel entrance has a high and steep uphill slope. Limited by the construction conditions at the time, the high and steep slopes at the tunnel entrance could not be effectively protected. With the continuous increase in the use of railways and highways, the slopes gradually weath...
