Abstract
Description
Technical Field
[0001] This utility model relates to the field of geological disaster prevention technology, and in particular to a debris flow protection device for geological disaster prevention. Background Technology
[0002] Debris flows are a type of geological disaster with immense destructive power. They erupt suddenly and often carry large amounts of mud, sand, rocks, and other materials, rushing downstream at extremely high speeds. In scenic areas and mountainous regions, the floor slabs of passageways are prone to debris flows due to the complex terrain, posing a serious threat to the personal safety and property of pedestrians and vehicles passing by.
[0003] Currently, Chinese patent CN221989137U discloses a debris flow protection structure, which is installed between a slope-prone debris flow area and a protected area. The slope-prone debris flow area has a gully. The protection structure is a linear structure with one end located on the side of the protected area adjacent to the gully, and the other end extending away from the gully and the protected area. The protection structure includes at least two retaining walls arranged radially, with a mesh connecting the ends of adjacent retaining walls. The extension direction of the protection structure forms an angle with the flow direction of the debris flow, which can intercept the debris flow and change its flow direction. By arranging the retaining walls and mesh alternately, some water or smaller particles in the debris flow are separated, reducing the forward flow of debris and thus reducing the distance required for the debris flow to stop, thereby reducing the size of the required protection structure. However, this debris flow protection structure only hinders the flow of debris. When a debris flow suddenly erupts, a large amount of debris will instantly overflow the retaining wall, burying the passageway and causing disasters such as traffic interruption, casualties, and property damage.

An installation plate 11 is provided on the top surface of the slope protection 1. One side of the installation plate 11 is connected to the top surface of the slope protection 1 via a connecting rod. The side of the installation plate 11 away from the slope protection 1 is fixed to the ground by a fixed column 9. A support frame 12 is vertically provided on the side of the installation plate 11 closest to the slope protection 1. A guide support plate 15 is provided between the top of the support frame 12 and the end of the installation plate 11 away from the slope protection 1. The guide support plate 15 is higher at one end of the support frame 12 and lower at the end away from the support frame 12, forming a slope. A connecting groove is provided on the top of the fixed column 9. The bottom four corners of the mounting plate 11 are fixedly equipped with connecting tenons 10, which fit into the connecting grooves. Threaded holes 13 are provided above the fixed column 9 and the connecting tenons 10, with bolts installed inside the threaded holes 13. The fixed column 9 and the connecting tenons 10 are fixedly connected by bolts. The mounting plate is fixed by the fixed column and the slope protection. The guide support plate installed on the mounting plate prevents the falling debris flow from flooding the road and affecting normal traffic. The guide support plate 15 is made of manganese steel plate. Several dampers 14 are provided between the guide support plate 15 and the mounting plate 11. Through multiple sets of dampers 14, the guide support plate 15 can withstand debris flow. The slope protection 1 provides buffering to reduce the impact of debris flows. It includes a debris flow drainage component, comprising a drainage ditch 6 located at the top of the slope protection 1. The drainage ditch 6 is connected to a drainage pipe 7, with the drainage end of the pipe 7 positioned above the road. The top surface of the drainage ditch 6 is equipped with several inlet grilles 8. A filter assembly is fixed between the bottom surface of the mounting plate 11 near the slope protection 1 and the top surface of the slope protection 1. The filter assembly includes a filter screen 17, which is a small-diameter steel wire mesh. A filter is fixed between the bottom surface of the mounting plate 11 near the slope protection 1 and the top surface of the slope protection 1. The filter assembly is a small-diameter steel wire mesh filter that filters impurities carried by the debris flow, allowing water to flow through the filter to the drainage ditch on the top of the slope, and then out through the drainage pipe, thus reducing the gravity of the debris flow. The inclined surface of the slope 1 is equipped with a reinforcement frame 3, which is fixed by the first fixing bolt 5. The reinforcement frame 3 is made of steel and has a grid-like distribution. Planting layers 4 are provided between the reinforcement frames 3 and are fixed together by welding or bolts.

The passageway base plate 18 can be a metal plate or a cement-cast plate, so that the bottom of the slope protection 1 and the bottom of the fixed column 9 form an integral load-bearing structure, increasing the stability of the entire device.
[0028] The implementation principle of a debris flow protection device for geological disaster prevention in this application embodiment is as follows: Multiple sets of fixed columns 9 are installed at intervals above the slope protection 1. The fixed columns 9 are made of high-strength reinforced concrete, with their bottoms extending a certain depth underground and fixed by concrete pouring to ensure sufficient stability. A connecting groove is provided at the top of each fixed column 9 unit for installing a guide support plate 15. The guide support plate 15 is made of metal and has anti-slip textures on its surface to increase the friction between the debris flow and the slope, preventing the debris flow from sliding rapidly above the guide support plate 15 and causing secondary impacts. Impact; A support frame 12 and a damper 14 are provided above the guide support plate 15. The support frame 12 supports the guide support plate 15, and the guide support plate 15 moves backward under the action of the damper 14 to absorb the impact force of the debris flow, reducing direct damage to the guide support plate 15 and increasing the support stability of the guide support plate 15. A mounting plate 11 is provided below the support frame 12. The mounting plate 11 matches the connecting groove at the top of the fixed column 9 through the connecting tenon 10 and is fixedly connected by bolts to ensure a stable connection between the guide support plate 15 and the fixed column 9. Multiple fixed columns 9 can be used to achieve stable support. Preferably, a metal grid 2 is provided between the two fixed columns 9 that are away from the support frame 12, such as Figure 1 As shown, to prevent mudslides from seeping between the fixed columns 9; a protective net is installed at the connection between the reinforcing frame 3 and the mounting plate 11 to prevent falling stones from falling into the drainage ditch 6 and causing water blockage, while the water can enter the drainage ditch 6 through the protective net for discharge, preventing excessive water flow from causing mudslides on the hillside. The reinforcing frame 3 consists of a horizontal frame and a vertical frame, forming an overall grid structure; both the horizontal and vertical frames are made of high-strength steel and are fixed together by welding or bolting; the reinforcing frame 3 can enhance the stability of the hillside, and the planting layer 4 can plant some plants with well-developed root systems, which can effectively prevent soil erosion.
