In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
Referring to fig. 1 and 2, the shed tunnel structure in one embodiment includes a shed tunnel disposed at one side of a mountain and a shock-absorbing device 10 for covering a road along a length direction of the road. The damping device 10 of the shed tunnel structure comprises a shielding plate 100, a supporting part 200 and an elastic part 300, wherein the shielding plate 100 is used for being arranged on the top 700 of the shed tunnel; one end of the supporting portion 200 is used for being disposed on the shed tunnel top 700, the other end of the supporting portion 200 is rotatably connected to the shielding plate 100, and the position where the shielding plate 100 is connected to the supporting portion 200 is a first rotating position 110; one end of the elastic part 300 is used for being rotatably arranged on the shed top 700, the other end of the elastic part 300 is rotatably connected to the shielding plate 100, the elastic part 300 is relatively spaced from the supporting part 200, the shielding plate 100 is connected with the elastic part 300 at a position of a second rotating position 120, the second rotating position 120 can rotate around the first rotating position 110, the height of the second rotating position 120 in the gravity direction is lower than the first rotating position 110, and the elastic part 300 can be stressed to be elastically deformed towards or away from the shed top 700. The supporting portion 200 is disposed on one side of the shed tunnel top 700 close to the mountain, and the elastic portion 300 is rotatably disposed on the other side of the shed tunnel top 700 far from the mountain.
Geological disasters such as collapse rock, landslide and debris flow cause serious threats to the traffic construction and transportation safety of China. In order to prevent the geological disasters from attacking, a shed tunnel structure is usually built on the road. The common reinforced concrete shed tunnel structure is extremely easy to be damaged due to the lack of a buffering and damping structure after being attacked by rolling stones. And because the shed tunnel structure is concreted, the structure is complicated, the maintenance process after the disaster is suffered is complicated, the construction period is long, and the maintenance efficiency is low. Meanwhile, in the prior art, the shielding plate 100 is directly used as the top of the shed tunnel, so that after a geological disaster occurs, if the shielding plate 100 is damaged, the geological disaster can also damage the road. Moreover, the shielding plate 100 and the shed tunnel structure are integrated, so that later maintenance work is inconvenient.
The damping means in this embodiment is set up with the shed tunnel having a complete roof structure. The shielding plate 100 can resist the invasion of a part of geological disasters, and if the shielding plate 100 is damaged, the shed tunnel structure still has a complete top structure to resist the invasion of the geological disasters, so that the safety of roads is further ensured.

And the height of the first rotation position 110 is greater than that of the second rotation position 120 so that the shielding plate 100 can be obliquely disposed on the shed roof 700. When geological disasters impact the shielding plate 100, the buffer part 400 is stressed to generate elastic deformation, so that the height of the buffer part 400 in the gravity direction is reduced, the inclined angle of the shielding plate 100 is increased, and the geological disasters are guided to flow to one side of the shed tunnel, which is back to the mountain. The damping device can effectively relieve the direct impact of the geological disaster on the shed tunnel, and potential safety hazards caused by accumulation of the geological disaster on the shed tunnel are avoided. Meanwhile, as the buffer part 400 can generate elastic deformation, the impact of geological disasters on the damping device is reduced, and the practicability and the reliability of the damping device are improved. And the two ends of the elastic part 300 can rotate relative to the shed tunnel top 700 and the shielding plate 100 respectively, so that when the elastic part 300 deforms under pressure, the whole elastic part 300 can incline relative to the shed tunnel top 700, and the second rotating position 120 is driven to rotate downwards around the first rotating position 110, as shown in the direction of R1 in fig. 2, the inclination angle of the shielding plate 100 is further increased, and the guiding and dredging of geological disasters are facilitated. When the elastic portion 300 is not pressed, the elastic portion 300 can push the second rotation portion 120 to rotate upward, which is the direction shown by R1, so as to restore the original state of the shock absorbing device. The elastic part 300 can adjust the inclination angle of the shielding plate 100 according to the scale of the geological disaster, smoothly guide the flow of the geological disaster, reduce the influence on the shed tunnel, and further improve the reliability and the practicability of the damping device. Simultaneously, damping device simple structure, the installation is swift, can effectively solve the loaded down with trivial details problem of later maintenance.

In most prior art, the shielding plate 100 is fixedly connected with the supporting portion 200, or the side of the shielding plate 100 connected with the supporting portion 200 is fixed in the mountain, which can cause the shielding plate 100 to generate torque when being impacted by geological disasters, so that the fixed end of the shielding plate 100 is deformed, and the structural stability of the whole shed tunnel is damaged. The receiving groove 130 is formed in the shielding plate 100, and the other end of the supporting portion 200 can be rotatably inserted into the receiving groove 130, so that the shielding plate 100 can be prevented from colliding with the supporting portion 200 in the rotating process to generate a torque.

In one embodiment, the rotating member is detachably coupled to the rotating shaft 140.

The sliding member 320 and the connecting member 330 are both able to rotate, so as to avoid torsion generated during the rotation of the shutter 100, and make the rotation of the shutter 100 more stable. The elastic member 310 can enable the sliding member 320 and the connecting member 330 to slide relative to each other, and can buffer the pressure of the shielding plate 100 during the pressing process, so as to store the pressure in the elastic member 310. When the shutter 100 is no longer compressed, the elastic member 310 can release the pressure, so that the slider 320 pushes the shutter 100 to return to the original position. The stability and the reliability of the damping device are ensured.
