Description

Technical Field

[0002] Currently, in mountainous areas with complex geological conditions, rockfall disasters occur frequently, posing a serious threat to transportation routes, buildings, and the safety of people. The existing rockfall protection shelter structure has the following problems: (1) Existing rockfall protection shelters mostly adopt simple rigid barrier structures and lack effective buffering measures. Faced with the impact of falling rocks, they cannot gradually dissipate the energy.

[0003] (2) The existing shed structure is fixed and difficult to adapt to different terrains, geological conditions and changing rockfall conditions.

[0004] (3) The existing protective tunnel structure is complex. When constructing in the narrow tunnel entrance, the site is limited, large equipment is difficult to operate, and the construction process is complicated, resulting in slow construction progress and increased costs.

[0037] Based on Embodiment 1 or Embodiment 5, in this embodiment, preferably, the shed roof panel assembly 5 includes a roof panel crossbeam 51, a support crossbeam fixing bolt 52, a support crossbeam fixing screw 53, a first multi-stage buffer support 54, a first shed roof panel fixing screw 55, and a first shed roof panel fixing bolt 56.

The shed roof panel is installed and fixed above the roof panel crossbeam by the shed roof panel fixing screws and bolts to ensure that the shed roof panel is firmly fixed. Example 7

[0039] Based on Embodiment 1 or Embodiment 6, in this embodiment, preferably, the upper chord fixing assembly 6 includes a third flipping rotation support rod 61, an upper chord crossbeam 62, an upper chord fixing plate 63, a second shed top plate diagonal brace 64, a second shed top plate fixing screw 65, a second shed top plate fixing bolt 66, and an upper chord crossbeam fixing bolt 67.

[0041] Based on Embodiment 1 or Embodiment 6, in this embodiment, preferably, the multi-stage buffer mechanism 7 includes a support support connecting rod 71, a support 72, a support connector 73, a support connecting bolt 74, a support connecting screw 75, a connecting rod fixing screw 76, a connecting rod fixing bolt 77, a multi-stage buffer plate 78, a buffer plate connecting rod bolt 79, a buffer plate connecting rod screw 710, a third multi-stage buffer support 711, a support connecting rod screw 712, a support connecting rod bolt 713, a buffer plate support screw 714, and a buffer plate support bolt 715. The third multi-stage buffer support 711 is fixedly connected to the support support connecting rod 71 and the multi-stage buffer plate 78 respectively.

[0042] In practical use, this multi-stage buffer mechanism consists of multiple multi-stage buffer plates and multi-stage buffer supports, installed using buffer plate support screws and bolts. The angles of the multi-stage buffer supports and multi-stage buffer plates are determined according to the terrain of the mountain. After the angles are determined, the supports and buffer plates are fixed to each other using connecting rods with connecting rod screws and bolts. Finally, the multi-stage buffer mechanism is fixedly connected to the mountain through supports and their corresponding connecting parts, thus realizing the assembly and fixation of the multi-stage buffer mechanism. This mechanism is mainly used to guide falling rocks. By using the buffer plates to cushion the impact energy of the falling rocks, the impact energy is reduced. As the falling rocks continuously impact the buffer plates from top to bottom, the energy of the falling rocks gradually decreases, thereby reducing the damage to the roof structure of the tunnel. In addition, some larger rocks may remain inside the buffer plates, which also facilitates the later cleanup of the falling rocks.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
