Description

Technical Field

[0001] The invention relates to a protective structure, in particular to a debris flow protective structure, and belongs to the technical field of debris flow protection. Background Art

[0002] Some rivers have sufficient hydropower resources, and the mountainous areas near the banks of the rivers have abundant wind and light resources, which provide good conditions for the site selection of clean energy bases, and can maximize the use of natural resources, optimize the energy structure, and promote 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, which bring great challenges to the layout of roads inside and outside the site and the reconstruction of roads. In order to meet the needs of the main project construction, the layout of roads often faces unfavorable factors such as bad terrain and geology. The gully locations in mountainous areas with poor geological conditions are mostly accompanied by mudslides due to rich material sources. At the same time, when building roads in mountainous areas, it is necessary to cut the foot of the slope, which has an adverse effect on the stability of the slope; when the rainfall is large, the mountain absorbs too much rainwater, resulting in reduced strength of the slope, soft soil, and poor slope stability. Under continuous rainfall, the scouring of rainwater can easily lead to soil loss in the mountain, thus forming mudslides. Once a mudslide disaster occurs, it will seriously affect traffic. The large amount of stones carried by the mudslide will also endanger personal safety, and at the same time pose a huge safety hazard to driving safety.

[0003] Protective walls are built at the foot of the mountain slopes on both sides of the highway. However, when the rainfall is heavy, the water will flow down the hillside due to the large amount of water. The water flow speed and impact force gradually increase, which can easily drive soil and stones to flow downward, and exert strong impact on the protective wall for a long time, causing the protective wall to collapse. Therefore, it is necessary to provide a debris flow protection structure to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] Embodiment 1:

[0034] This embodiment provides a debris flow protection structure, which can not only slow down the flow speed of debris flow, reduce the impact force of debris flow, and reduce the damage to the protection wall; it can also better retain the sediments in the debris flow, reduce the impact of sediment on downstream areas, and contribute to land and ecological protection.

[0035] like Figure 1 and Figure 2 As shown, the debris flow protection structure includes a slope 1 and a mounting plate 2 arranged on the surface of the slope 1; the mounting plate 2 is fixed to the surface of the slope 1 by a pre-assembled part 3, and a buffer component 4 and a fixing component 5 are arranged on the surface of the mounting plate 2, wherein the buffer component 4 is fixed to the surface of the mounting 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 spaced apart along the slope direction of the slope 1, each row has more than one buffer component, and adjacent rows of buffer components 4 are staggered), thereby effectively dispersing the impact force of debris flow or landslide, reducing the direct impact on the underlying structure, and improving the overall protection effect.

[0037] like Figure 3As shown, a rectangular mounting groove 201 for mounting the buffer assembly 4 is provided on the surface of the mounting plate 2 (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 body 1; a drainage groove 204 is provided on the inner wall of the mounting groove 201 and runs horizontally through the mounting plate 2; a protective plate 202 is fixed on the surface of the mounting plate 2 at the lower end of the mounting groove 201 along the slope direction, and the protective plate 202 includes two triangular side panels arranged opposite to each other and an inclined plate arranged at one end of the two triangular side panels and connected to the hypotenuse of the two triangular side panels at the end, and the inclined plate 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 component 4 contacts 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; the buffer plate 402 and the protective plate 202 form an acute angle with the slope 1, and the debris flow will have a greater impact when reaching the buffer plate 402, which helps to more effectively intercept and slow down the flow of the debris flow and enhance its protective effect. In addition, the acute angle design increases the path and time of the debris flow flowing on the buffer component 4, giving the debris flow more opportunities for collision and friction, thereby further slowing down its movement speed.

[0038] In addition, a fixing groove 205 is provided on the inner bottom surface of the installation 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 clamped in 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 tilted, and the tilt angle is consistent with the tilt angle of the protective plate 202; fixing bolts 203 are passed through the two triangular side panels of the protective plate 202, and fixing holes 404 are provided at corresponding positions on both sides of the buffer plate 402, and the protective plate 202 is fixedly connected to the buffer plate 402 by 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 arranged between the buffer plate 402 and the fixed plate 401, and the upper surface of the reinforcing plate 403 is fixed on the inner inclined surface of the buffer plate 402, and the lower surface is fixed on the surface of the fixed plate 401; a drainage cavity 407 can be formed between the fixed plate 401, the buffer plate 402 and the reinforcing plate 403; the two triangular side panels 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 connected to the drainage cavity 407 are opened on the surface of the reinforcing plate 403.

[0041] The working principle of the debris flow protection structure is as follows: first, the device is installed on the surface of the slope 1. When the debris flow flows downward along the slope 1, the buffer plate 402 can buffer the debris flow. At the same time, the drainage holes 405 opened on the surface of the reinforcing plate 403 can separate the water in the debris flow and discharge it through the drainage cavity and the drainage groove 204, so as to 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 landslide or debris flow.

[0042] The debris flow protection structure can not only slow down the flow speed of the debris flow, reduce the impact force of the debris flow, and reduce the damage to the protection wall through the installation plate 2 and the buffer component 4; it can also better retain the sediments in the debris flow, reduce the impact of sediment on the downstream area, 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] Embodiment 2:

[0044] Based on the above-mentioned 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 pushing block 506 and a fixing block 504; a transmission compartment 406 is provided at a position inside the fixing plate 401 for installing the fixing component 5; a through hole connected to the transmission compartment 406 is provided on the surface of the fixing plate 401 for installing 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 compartment 406 after being supported by a bearing; the threaded tube 503 can be threadedly matched with the threaded rod 502 through an internal thread; and the pushing 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 slide groove is provided at a corresponding position on the surface of the transmission chamber 406, and the slider 509 slides in cooperation with the slide groove; thus, the threaded tube 503 is movably connected in the transmission chamber 406 through the slider 509 and the slide groove. There are two sets of sliders 509 and slide grooves, and they 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, and a central blind hole is set in the center of the fixing block 504 for the threaded tube 503 and the pushing block 506 to pass through; a fixing groove 205 is opened at the inner bottom surface of the installation groove 201 at a position corresponding to the transmission compartment 406; the fixing block 504 is clamped in the fixing groove 205. In the fixed block 504, telescopic grooves 505 are provided on both sides of its central blind hole along the slope direction of the slope body 1, and the telescopic grooves 505 are connected with its central blind hole (that is, the telescopic grooves 505 are connected with the transmission compartment 406 through the central blind hole); limiting grooves 206 are provided on the two opposite inner wall surfaces of the fixed groove 205 at positions corresponding to the telescopic grooves 505; a limiting rod 507 is provided inside each telescopic groove 505, and the limiting rod 507 is slidably matched with the telescopic groove 505 and can move in the telescopic groove 505; before the push block 506 is inserted, the limiting rod 507 is located in the telescopic groove 505, and after the push block 506 is inserted, one end of the limiting rod 507 is in contact with the push block 506, and the other end of the limiting rod 507 can pass through the fixed block 504 and be clamped in the limiting groove 206.

[0048] The limiting rods 507 on both sides of the pushing block 506 are perpendicular to the pushing block 506, and the fitting surfaces of the limiting rods 507 on both sides and the pushing block 506 are both inclined surfaces (that is, the fitting 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 is in contact with the inner bottom surface of the telescopic groove 505, and the other end is in contact with the annular protrusion set on the limiting rod 507; thus, the two limiting rods 507 with springs 508 are symmetrically arranged on both sides of the pushing block 506.

[0049] Therefore, when installing the buffer component 4, it is only necessary to turn the knob 501 to drive the threaded rod 502 to rotate, and then drive the threaded tube 503 to move axially along the slide groove, and the threaded tube 503 drives the push block 506 to move axially; since the contact surfaces of the push block 506 and the limit rod 507 are inclined surfaces, the push block 506 can push the limit rod 507 to move during the movement (the spring 508 is compressed at this time), so that one end of the limit rod 507 is clamped in the limit groove 206, and the buffer component 4 can be fixed.

[0050] The fixing assembly 5 using this structural form can quickly install and disassemble the buffer assembly 4, reduce downtime, improve work efficiency, and can effectively prevent the buffer assembly 4 from being displaced or tilted due to impact, ensuring its stability during use.

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

[0052] First, the mounting plate 2 is mounted on the surface of the slope 1 through the pre-assembled part 3, and then the buffer assembly 4 is placed in the mounting groove 201 according to the tilting direction of the protective plate 202; at the same time, the fixing block 504 is engaged with the fixing groove 205, and then the knob 501 is turned to drive the threaded rod 502 to rotate, and the threaded rod 502 drives the threaded tube 503 to move, and the threaded tube 503 drives the pushing block 506 to move. Since the contact surface between the pushing block 506 and the limiting rod 507 is an inclined surface, the pushing 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, thereby completing the fixation of the buffer assembly 4.

[0053] When the debris flow flows downward along the slope 1 , the buffer plate 402 can buffer the debris flow, and the drainage holes 405 opened on the surface of the reinforcing plate 403 can separate the water in the debris flow and discharge it through the drainage cavity 407 and the drainage groove 204 .

[0054] The setting of the buffer component 4 can significantly reduce the impact force of the debris flow, protect the slope 1 and the protected area below, and the drainage hole 405 design on the surface of the reinforcing plate 403 can quickly and effectively separate the moisture in the debris flow, reduce the potential impact of the water flow on the downstream area, and through the combination of the drainage cavity and the drainage groove 204, ensure that excess moisture can be quickly discharged, reduce harm to the environment, and reduce the risk of debris flow; at the same time, through the locking mechanism of the fixed component 5, ensure that the buffer component 4 will not be displaced when impacted, thereby ensuring the stability of the buffer component 4.

[0055] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
