Abstract

This utility model belongs to the technical field of rockfall protection shelter structures, and specifically relates to a double-layer protective rockfall collection shelter structure. A double-layer protective rockfall collection shelter structure includes columns, a three-bar support assembly above the columns, a top plate supported above the three-bar support assembly, canopy components at both ends of the top plate, canopy netting supported above the canopy components, and double-wing mesh support components on both sides of the top plate, with double-wing meshting on the double-wing mesh support components. This utility model, through its double-layer protective structure design, ensures that the canopy structure contacts the falling rock first. Using flexible protective netting and other components, the deformation of the netting absorbs and dissipates some of the impact energy of the falling rock. The designed canopy components guide the falling rock to the double-wing meshting on both sides of the shelter, causing the rock to slide down in a specific direction, facilitating centralized rockfall cleanup, preventing the falling rock from scattering and accumulating on roads or power lines, affecting traffic or increasing cleanup difficulty, and reducing the impact on power lines.

Description

Technical Field

[0001] This utility model belongs to the technical field of rockfall protection shed structure, and specifically relates to a double-layer rockfall collection shed structure. Background Technology

[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) Most existing rockfall protection shelters adopt a single-layer reinforced concrete roof structure. The single-layer structure lacks a graded energy dissipation mechanism, making it difficult to disperse impact loads and posing safety hazards.

[0003] (2) Conventional tunnels only focus on passive interception and do not solve the problem of subsequent rockfall accumulation. After the rockfall impact, the debris is scattered on the track or road surface, which requires manual cleaning and affects the efficiency of traffic resumption.

[0004] (3) Existing protective sheds require overall repair or replacement of single-layer roof slabs after damage, which has a long construction period and poor economic efficiency.

[0005] (4) Existing designs often excessively increase the thickness of the top slab or the reinforcement ratio, resulting in material waste and excessive structural weight.

[0006] (5) In areas with high rockfall energy, such as steep slopes and canyons, single-layer structures need to be equipped with additional buffer layers (such as geogrids and gravel cushions), which increases the difficulty of construction and has limited effect. Utility Model Content

[0007] To address the aforementioned problems, the purpose of this utility model is to provide a double-layer protective rockfall collection tunnel structure. Through this double-layer design, the roof structure contacts the falling rock first, employing flexible protective netting and other components that utilize their deformation to absorb and dissipate some of the impact energy. The designed roof components guide the falling rock to the double-wing hanging netting on both sides of the tunnel, causing it to slide down in a specific direction. This facilitates centralized rockfall collection and prevents the rock from scattering and accumulating on roads or railway lines, thus avoiding traffic disruptions or increased collection difficulty, reducing the impact on railway lines, and lowering the risk of the rock falling back onto the lines. This structure reduces the impact of falling rocks on the inner tunnel structure, preventing them from penetrating and intruding into the railway, highway, or other railway lines below, protecting the safety of vehicles, pedestrians, and equipment on the lines.

[0008] The technical solution of this utility model is as follows: a double-layer protective rockfall collection shed structure, including a column, a three-bar support assembly above the column, a top plate above the three-bar support assembly, a canopy assembly at both ends of the top plate, a canopy net above the canopy assembly, and a double-wing net frame support assembly on both sides of the top plate, with a double-wing net on the double-wing net frame support assembly.

[0009] The three-bar support assembly includes three diagonal supports connected end to end. Each diagonal support has a lower fixing screw, a lower fixing bolt, and a lower fixing plate on both sides of its bottom. The bottoms of adjacent diagonal supports are fixed by fixing screws and lower fixing bolts passing through the lower fixing plates. At the top connection point, the three-bar support has an upper fixing screw, an upper fixing bolt, and an upper fixing plate. The tops of adjacent diagonal supports are fixed by upper fixing screws and upper fixing bolts passing through the upper fixing plates.

[0010] The dual-wing support assembly includes a column lower fixing screw, a column lower fixing bolt, a dual-wing frame diagonal brace, a diagonal brace fixing screw, a diagonal brace fixing bolt, a dual-wing frame, a column, a column upper fixing screw, and a column upper fixing bolt. The dual-wing frame and the column are fixedly connected by the column upper fixing screw and the column upper fixing bolt. The dual-wing frame diagonal brace is fixedly connected to the column and the dual-wing frame by the column lower fixing screw and the column lower fixing bolt, the diagonal brace fixing screw, and the diagonal brace fixing bolt, respectively.

[0011] The canopy assembly includes an upper crossbeam, multiple upper support rods perpendicular to the upper crossbeam, an upper connecting rod, a diagonal support, a lower connecting rod, a lower support rod, and a lower crossbeam perpendicular to the lower support rod. The upper crossbeam and the upper support rod are connected by canopy plate fixing screws and bolts. The upper support rod and the upper connecting rod are connected by upper connecting rod fixing bolts and upper connecting rod fixing screws. The lower connecting rod and the lower support rod are connected by lower connecting rod fixing bolts and lower connecting rod fixing screws. The lower support rod and the lower crossbeam are connected by lower connecting screws and lower bolts.

[0012] The technical advantages of this invention are as follows: Through its double-layer protective structure design, the canopy structure contacts the falling rocks first. Flexible protective netting and other components absorb and dissipate some of the impact energy of the falling rocks through deformation. The designed canopy components guide the falling rocks to the double-wing hanging netting on both sides of the canopy, causing them to slide down in a specific direction. This facilitates centralized cleanup of the rocks, preventing them from scattering and accumulating on roads or railway lines, thus avoiding traffic disruptions or increased cleanup difficulties, reducing the impact on railway lines, and lowering the risk of rocks rolling back onto the lines. This structure reduces the impact of falling rocks on the inner canopy structure, preventing them from penetrating and intruding into the railway, highway, or other railway lines below, protecting the safety of vehicles, pedestrians, and equipment on the lines.
