Description

Technical Field

[0001] This invention relates to a protective structure, specifically a debris flow protection structure, and belongs to the field of debris flow protection technology. Background Technology

[0002] Some rivers possess ample hydropower resources, while the mountainous areas along their banks offer abundant wind and solar resources, providing favorable conditions for the site selection of clean energy bases. This allows for the maximization of natural resource utilization, optimization of energy structure, and promotion of economic development. Most clean energy base projects, such as hydropower stations and mountain wind farms, are located in mountainous and hilly areas with steep terrain and complex geological conditions. This presents significant challenges to the layout of on-site and off-site roads, as well as the reconstruction and renovation of existing roads. Furthermore, to meet the needs of the main construction projects, road layout often faces unfavorable factors such as poor terrain and geology. Mountainous gullies with poor geological conditions, due to abundant sediment resources, are often accompanied by debris flows. Simultaneously, road construction in mountainous areas requires cutting the slope toe, adversely affecting slope stability. During periods of heavy rainfall, excessive rainwater absorption by the mountains reduces slope strength, softens the soil, and worsens slope stability. Under continuous rainfall, the erosion action of rainwater easily leads to soil erosion, resulting in debris flows. Once a mudslide occurs, it will severely affect traffic. The large number of rocks carried by the mudslide will also endanger personal safety and pose a great safety hazard to driving.

[0003] Protective walls are typically built at the foot of mountain slopes along highways. However, during periods of heavy rainfall, the large volume of water flows downhill, increasing in speed and impact force. This can easily carry debris and rocks downhill, subjecting the protective walls to prolonged and intense impacts, ultimately causing them to collapse. Therefore, it is necessary to provide a debris flow protection structure to address these issues. Summary of the Invention

[0013] The surfaces of the limiting rods on both sides that face the pushing block are inclined surfaces; a spring is sleeved on the outer circumference of the limiting rod, one end of the spring abuts against the inner bottom surface of the telescopic groove, and the other end abuts against the annular protrusion provided on the limiting rod;

[0014] Before the push block is inserted, the limiting rod is located in the telescopic groove; after the push block is inserted, one end of the limiting rod is in contact with the push block, and the other end of the limiting rod can pass through the fixing block and be engaged in the limiting groove.

[0021] Beneficial effects:

[0022] (1) The present invention can not only slow down the flow speed of debris flow and reduce the impact force of debris flow by installing plates and buffer components, and reduce the damage to the retaining wall, but also better retain the sediment in the debris flow and reduce the impact of mud and sand on downstream areas, which is conducive to land and ecological protection.

When the debris flow reaches the buffer plate, it will generate a large impact, which helps to more effectively intercept and slow down the flow of debris flow, enhance its protective effect, and the acute angle design increases the path and time of debris flow on the buffer component, giving the debris flow more opportunities to collide and rub, thereby further slowing down its movement speed.

[0024] (3) The buffer component in this invention can also separate water in debris flow, disperse water flow pressure in debris flow, reduce water erosion on slope, and reduce the possibility of secondary landslides or debris flows.

[0025] (4) In this invention, the staggered arrangement of multiple buffer components can effectively disperse the impact force of debris flow or landslide, reduce the direct impact on the underlying structure, and improve the overall protection effect. Attached Figure Description

Detailed Implementation

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0033] Example 1:

[0034] This embodiment provides a debris flow protection structure that can not only slow down the flow velocity of debris flows and reduce their impact force, thus minimizing damage to the protective wall, but also better retain sediments in the debris flow, reducing the impact of mud and sand on downstream areas, and contributing to land and ecological protection.

[0035] like Figure 1 and Figure 2 As shown, the debris flow protection structure includes a slope 1 and an installation plate 2 set on the surface of the slope 1; the installation plate 2 is fixed to the surface of the slope 1 by a pre-installed component 3, and a buffer component 4 and a fixing component 5 are provided on the surface of the installation plate 2, wherein the buffer component 4 is fixed to the surface of the installation plate 2 by the fixing component 5; the buffer component 4 is used to intercept and slow down the flow of debris flow.

[0036] As an example, multiple buffer components 4 are staggered on the surface of the mounting plate 2 and arranged in a stepped manner along the slope direction of the slope 1 (that is, multiple rows of buffer components 4 can be distributed at intervals along the slope direction of the slope 1, with each row having more than one buffer component, and the buffer components 4 in adjacent rows are staggered). This can effectively disperse the impact force of debris flow or landslide, reduce the direct impact on the structure below, and improve the overall protection effect.

[0037] like Figure 3As shown, the surface of the mounting plate 2 is provided with a rectangular mounting groove 201 for mounting the buffer assembly 4 (one mounting groove 201 is provided for each buffer assembly 4), and the length direction of the rectangular mounting groove 201 is along the slope direction of the slope 1; the inner wall of the mounting groove 201 is provided with a drainage groove 204 that runs horizontally through the mounting plate 2; a protective plate 202 is fixed to the surface of the mounting plate 2 at the lower end of the mounting groove 201 along the slope direction, the protective plate 202 includes two opposing triangular side plates and an inclined plate provided at one end of the two triangular side plates and connected to the hypotenuse of that end of the two triangular side plates. The angle between the buffer plate 402 and the surface of the slope 1 is an acute angle; the buffer plate 402 in the buffer assembly 4 abuts against the inclined plate of the protective plate 202, and the angle between the buffer plate 402 and the surface of the slope 1 is also an acute angle; through the acute angle formed between the buffer plate 402 and the protective plate 202 and the slope 1, the debris flow will generate a large impact when it reaches the buffer plate 402, which helps to more effectively intercept and slow down the flow of the debris flow, enhance its protective effect, and the acute angle design increases the path and time of the debris flow on the buffer assembly 4, giving the debris flow more opportunities to collide and rub, thereby further slowing down its movement speed.

[0038] In addition, a fixing groove 205 is provided on the bottom surface of the mounting groove 201 for cooperating with the fixing component 5.

[0039] like Figure 4 As shown, the buffer assembly 4 includes: a fixing plate 401, a buffer plate 402, and a reinforcing plate 403; the fixing plate 401 is snapped into the corresponding mounting groove 201, the buffer plate 402 is fixed to the surface of one end of the fixing plate 401 in the length direction, the buffer plate 402 is inclined, and the inclination angle is the same as the inclination angle of the protective plate 202; fixing bolts 203 are provided on the two triangular side plates of the protective plate 202, and fixing holes 404 are provided on the two sides of the buffer plate 402 at corresponding positions, and the protective plate 202 is fixedly connected to the buffer plate 402 through the cooperation of the fixing bolts 203 and the fixing holes 404; after connection, the outer inclined surface of the buffer plate 402 abuts against the inner inclined surface of the protective plate 202.

[0040] A reinforcing plate 403 is provided between the buffer plate 402 and the fixed plate 401. The upper surface of the reinforcing plate 403 is fixed to the inner inclined surface of the buffer plate 402, and the lower surface is fixed to the surface of the fixed plate 401. The fixed plate 401, the buffer plate 402 and the reinforcing plate 403 can form a drainage cavity 407. The two triangular side plates of the protective plate 202 cover the two sides of the drainage cavity 407. The drainage groove 204 is connected to the drainage cavity 407. In addition, a plurality of evenly arranged drainage holes 405 communicating with the drainage cavity 407 are provided on the surface of the reinforcing plate 403.

[0041] The working principle of this debris flow protection structure is as follows: First, the device is installed on the surface of the slope 1. When the debris flow flows down the slope 1, the buffer plate 402 can buffer the debris flow. At the same time, the drainage holes 405 on the surface of the reinforcing plate 403 can separate the water in the debris flow and discharge it through the drainage chamber and drainage channel 204. This separates the water in the debris flow, disperses the water flow pressure in the debris flow, reduces the scouring of the slope by water, and reduces the possibility of secondary landslides or debris flows.

[0042] This debris flow protection structure, through the installation plate 2 and buffer component 4, can not only slow down the flow velocity of the debris flow, reduce the impact force of the debris flow, and reduce damage to the protective wall; it can also better retain the sediment in the debris flow, reduce the impact of mud and sand on downstream areas, and contribute to land and ecological protection; at the same time, the buffer component 4 can also separate the water in the debris flow, disperse the water flow pressure in the debris flow, reduce the scouring of the slope by water, and reduce the possibility of secondary landslides or debris flows.

[0043] Example 2:

[0044] Based on the above embodiment 1, this embodiment provides a preferred structural form of the fixing component 5.

[0045] like Figure 5 As shown, the fixing component 5 includes: a knob 501, a threaded rod 502, a threaded tube 503, a push block 506, and a fixing block 504; a transmission chamber 406 is provided inside the fixing plate 401 for mounting the fixing component 5; a through hole communicating with the transmission chamber 406 is provided on the surface of the fixing plate 401 for mounting the knob 501; the upper end of the knob 501 protrudes from the surface of the fixing plate 401; the upper end of the threaded rod 502 is fixed to the lower surface of the knob 501, and the lower end of the threaded rod 502 passes through the transmission chamber 406 after being supported by a bearing; the threaded tube 503 can be threadedly engaged with the threaded rod 502 through its internal thread; the push block 506 is fixed to the lower end of the threaded tube 503.

[0046] A slider 509 is fixed to the side of the threaded tube 503, and a corresponding groove is provided on the surface of the transmission chamber 406. The slider 509 slides in conjunction with the groove. Thus, the threaded tube 503 is movably connected to the transmission chamber 406 through the slider 509 and the groove. There are two sets of sliders 509 and grooves, which are symmetrically arranged on both sides of the threaded tube 503.

[0047] The fixing block 504 is fixed on the lower surface of the fixing plate 401. The center of the fixing block 504 is provided with a central blind hole for the threaded tube 503 and the push block 506 to pass through. The bottom surface of the mounting groove 201 is provided with a fixing groove 205 corresponding to the position of the transmission chamber 406. The fixing block 504 is snapped into the fixing groove 205. The fixed block 504 has expansion grooves 505 on both sides of its central blind hole along the slope direction of the slope 1. The expansion grooves 505 are connected to the central blind hole (that is, the expansion grooves 505 are connected to the transmission chamber 406 through the central blind hole). The fixed groove 205 has limit grooves 206 on two opposite inner wall surfaces corresponding to the expansion grooves 505. Each expansion groove 505 has a limit rod 507 inside. The limit rod 507 slides with the expansion groove 505 and can move within the expansion groove 505. Before the push block 506 is inserted, the limit rod 507 is located in the expansion groove 505. After the push block 506 is inserted, one end of the limit rod 507 is in contact with the push block 506, and the other end of the limit rod 507 can pass through the fixed block 504 and be engaged in the limit groove 206.

[0048] The limiting rods 507 on both sides of the pushing block 506 are perpendicular to the pushing block 506, and the contact surfaces of the limiting rods 507 and the pushing block 506 are inclined surfaces (i.e., the mating surfaces of the two are wedge-shaped surfaces); a spring 508 is sleeved on the outer circumference of the limiting rod 507, one end of the spring 508 abuts against the inner bottom surface of the telescopic groove 505, and the other end abuts against the annular protrusion provided on the limiting rod 507; thus, two limiting rods 507 with springs 508 are symmetrically arranged on both sides of the pushing block 506.

[0049] Therefore, when installing the buffer assembly 4, simply turn the knob 501 to rotate the threaded rod 502, which in turn drives the threaded tube 503 to move axially along the slide groove. The threaded tube 503 then drives the push block 506 to move axially. Since the contact surfaces of the push block 506 and the limiting rod 507 are inclined, the push block 506 can push the limiting rod 507 to move during its movement (compressing the spring 508 at this time), thereby making one end of the limiting rod 507 engage in the limiting groove 206, thus completing the fixation of the buffer assembly 4.

[0050] The fixed component 5 with this structural form can quickly install and disassemble the buffer component 4, reduce downtime, improve work efficiency, and effectively prevent the buffer component 4 from shifting or tilting due to impact, ensuring its stability during use.

[0051] The installation process of the above-mentioned debris flow protection structure is as follows:

[0052] First, the mounting plate 2 is installed on the surface of the slope 1 using the pre-installed component 3. Then, the buffer assembly 4 is placed into the mounting groove 201 according to the inclined direction of the protective plate 202. At the same time, the fixing block 504 is engaged in the fixing groove 205. Then, the knob 501 is turned to drive the threaded rod 502 to rotate. The threaded rod 502 drives the threaded tube 503 to move. The threaded tube 503 drives the push block 506 to move. Since the contact surface between the push block 506 and the limiting rod 507 is inclined, the push block 506 can push the limiting rod 507 to move during the movement, so that one end of the limiting rod 507 is engaged in the limiting groove 206, thus completing the fixation of the buffer assembly 4.

[0053] When the debris flow flows down the slope 1, the buffer plate 402 can buffer the debris flow, while the drainage holes 405 on the surface of the reinforcing plate 403 can separate the water in the debris flow and discharge it through the drainage chamber 407 and the drainage channel 204.

[0054] The buffer component 4 significantly reduces the impact of debris flow, protecting the slope 1 and the protected area below. The drainage holes 405 on the surface of the reinforcing plate 403 can quickly and effectively separate water from the debris flow, reducing the potential impact of the water flow on the downstream area. The combination of the drainage chamber and the drainage channel 204 ensures that excess water can be discharged quickly, reducing harm to the environment and lowering the risk of debris flow. At the same time, the locking mechanism of the fixing component 5 ensures that the buffer component 4 will not shift when impacted, ensuring the stability of the buffer component 4.

[0055] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
