Description

Technical Field

[0001] The invention relates to the technical field of slope surface protection, and in particular to a slope surface protection device used for preventing and controlling debris flow geological disasters. Background Art

[0002] Debris flow is a natural disaster that usually occurs in mountainous or plateau areas. It is caused by heavy rain, snowmelt or other water sources, leading to geological disasters such as landslides and collapses, and then forming a special torrent carrying a large amount of solid materials such as mud, stones and boulders. Debris flow will carry a large amount of solid materials such as mud, stones and boulders during the flow process. These materials have strong erosion ability when flowing at high speed. When the debris flow flows through the slope surface, it will wash and erode the soil and vegetation on the slope surface, causing the soil layer on the slope surface to become thinner, and even expose the bedrock. This erosion not only destroys the original landform of the slope surface, but may also cause the stability of the slope to decrease, increasing the risk of geological disasters such as landslides.

[0003] In order to deal with the risk of landslides that may be caused by debris flows, the slope surface needs to be reinforced in advance, which can not only prevent the risk of sliding, but also avoid geological disasters such as collapse. Common slope reinforcement methods include using a slope surface protection device for debris flow geological disaster prevention and control such as the prior art publication number CN218622282U, or using a slope surface protection device such as the prior art publication number CN118686205A. These two slope surface protection devices are the same as traditional slope surface reinforcement methods. They all use a mesh protection net to cover the slope surface. The protection net can be used to cover and wrap the slope or rock to be protected, limiting the weathering, peeling or damage of the rock soil on the slope surface, thereby playing a reinforcement role. It can also control the movement of falling rocks within a certain range to prevent falling rocks from causing damage to personnel and facilities below the slope.

[0004] However, the existing protection nets are mostly fixed directly on the slope surface. Once the mountain slides, the protection nets are easily involved in the debris flow, affecting the protection effect. In addition, the prior art CN118686205A also adds a retaining wall to block the debris flow. However, when the debris flow carries a lot of solid matter, the impact force of the debris flow itself can easily destroy the retaining wall, thus failing to achieve the protection effect. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide a slope protection device for preventing and controlling debris flow geological disasters, so as to solve the problems in the prior art that the protection net is easily washed away by the debris flow and the debris flow easily destroys the retaining wall.

An electromagnetic valve is fixed on the outer end of the reinforcement box connecting pipe for introducing the water flow inside the triangular reinforcement box a into the triangular reinforcement box b to increase the weight of the triangular reinforcement box b.

[0012] Furthermore, there are two connecting pipes of the reinforcement box, and a solenoid valve is fixed at the outer end of each connecting pipe of the reinforcement box. A control mechanism for controlling the opening and closing of the solenoid valve is provided on the top of the triangular reinforcement box a. The control mechanism controls the solenoid valve to open only after the water flow inside the triangular reinforcement box a is full, so as to introduce excess water into the interior of the triangular reinforcement box b.

[0013] Furthermore, a plurality of drainage holes connected to the interior of the triangular reinforcement box b are provided at the top of the triangular reinforcement box b, which are used to drain excess water after the interior of the triangular reinforcement box b is filled with water, thereby ensuring normal drainage in heavy rain or continuous rainfall.

[0014] Furthermore, the control mechanism includes a control box fixed in the middle of the top of the triangular reinforcement box a, a water hole for connecting to the control box is opened inside the triangular reinforcement box a, a piston plate is provided at the bottom end of the control box, a short rod and a spring are fixed to the top of the piston plate, the short rod is located inside the spring, the top of the short rod is fixed to the top of the inner cavity of the control box, a touch switch for controlling the opening and closing of the solenoid valve is provided at the top of the inner cavity of the control box, the water flow inside the triangular reinforcement box a enters the control box through the water hole, pushes the piston plate to drive the short rod to move upward until the short rod contacts the touch switch, and then the solenoid valve opens.

[0015] Furthermore, the cross-sectional shape of the piston plate and the cross-sectional shape of the inner cavity of the control box are both circular.

[0022] The water flow that scours the slope surface is also led down the slope surface by utilizing the water diversion channel and the water diversion platform to reduce the scouring effect of the water flow on the slope surface, which is helpful to prevent the formation of mud and rock flow. At the same time, the downward water flow is introduced into the triangular reinforcement box a and the triangular reinforcement box b. The weight of the triangular reinforcement box a and the triangular reinforcement box b after being filled with water increases, which can further support the retaining wall, thereby improving the reinforcement effect, killing two birds with one stone.

In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0039] In addition, the term "same" does not mean that the parts must be absolutely the same, but slight differences are allowed. The term "vertical" only means that the positional relationship between the parts is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly tilted.

[0040] See also Figure 1-8The present invention provides a technical solution: a slope surface protection device for preventing and controlling debris flow geological disasters, comprising a retaining wall 1 arranged at the bottom of the slope surface, a protective net assembly 2 is arranged on the side of the retaining wall 1 facing the slope surface, the protective net assembly 2 is laid on the slope surface, and water diversion channels 3 are arranged on both sides of the protective net assembly 2. A plurality of reinforcement anchor rods 6 are fixed to the bottom of the retaining wall 1 and the bottom of the water diversion channel 3, and the reinforcement anchor rods 6 are buried in the slope. The reinforcement anchor rods 6 vertically inserted into the slope can not only fix the retaining wall 1 and the water diversion channel 3, but also reinforce the slope body to improve the stability of the slope.

[0041] The protection net assembly 2 is fixed together with the water diversion channel 3. The protection net assembly 2 includes a plurality of front fixing ropes 22 and a plurality of rear fixing ropes 23. Each front fixing rope 22 and each rear fixing rope 23 form a group. A plurality of mesh pieces 21 are arranged between the front fixing ropes 22 and the rear fixing ropes 23 in each group. Different from the traditional protection net, the protection net in the present invention is composed of a plurality of independent small mesh pieces 21. This arrangement can select mesh pieces 21 of different mesh sizes for different landform features on the same slope surface, thereby improving the protection effect.

[0042] In this embodiment, both ends of the front fixing rope 22 and both ends of the rear fixing rope 23 pass through the water diversion channel 3 located on both sides thereof, and both ends of the front fixing rope 22 and both ends of the rear fixing rope 23 are fixed with limit plates 24, and the limit plates 24 are fixed to the side of the water diversion channel 3 away from the mesh 21. During construction, through holes for the front fixing rope 22 and the rear fixing rope 23 to pass through are reserved in advance on the water diversion channel 3, and then one end of the mesh 21 is first passed through a through hole on the water diversion channel 3 in a sequence from left to right or from right to left, and then the end of the mesh 21 is passed through the grid at the front end of the mesh 21 in an S shape in sequence, and finally passed through the other Through holes on the water diversion channel 3, similarly, when installing the rear fixing rope 23, first pass one end of the rear fixing rope 23 through a through hole on the water diversion channel 3, then pass the end of the rear fixing rope 23 through the grids at the rear end of the mesh 21 in an S shape in sequence, and finally pass through the through hole on another water diversion channel 3, so as to achieve the effect of fixing the mesh 21 with the front fixing rope 22 and the rear fixing rope 23, and then install the upper limit plates 24 at both ends of the front fixing rope 22 and the rear fixing rope 23 respectively, and fix the limit plates 24 to the outer wall of the water diversion channel 3 with bolts, and in this process, tighten the front fixing rope 22 and the rear fixing rope 23 to achieve fixation;

[0043] In order to improve the stability of the connection between the meshes 21, the present invention also uses a binding rope to fix two adjacent meshes 21 together, so that multiple independent meshes 21 can be connected into a whole, and the protection effect of the slope surface can be further enhanced through the interaction between the multiple meshes 21;

[0044] like Figure 4As shown, because the fixing height of the front fixing rope 22 is higher than the fixing height of the rear fixing rope 23, and the length of the front fixing rope 22 is greater than the length of the rear fixing rope 23, the present invention provides two clamps 25 at the outer end of the front fixing rope 22. After the mesh 21 and the front fixing rope 22 are connected together, the clamp 25 is used to cover the outer end of the front fixing rope 22, and then the part of the front fixing rope 22 that is longer than the rear fixing rope 23 is fixed to the inner wall of the water diversion channel 3 by bolts, so that the bottom ends of the front fixing rope 22 and the rear fixing rope 23 can both contact the slope surface, thereby fixing the mesh 21 on the slope surface.

[0045] Through the unique arrangement of the front fixing rope 22 and the rear fixing rope 23, after the solid materials such as mud, stones and boulders carried by the debris flow lift up the front end of the mesh 21, the mesh 21 can be restricted by the front fixing rope 22 and the rear fixing rope 23 to form a Figure 8 The state shown: the area formed between the mesh 21 and the slope surface is open at the front end and blocked at the rear end. At this time, the mesh 21 is in the shape of a net bag, which can prevent the solid matter carried by the debris flow from moving down the slope surface, thereby reducing the impact of the debris flow on the retaining wall 1 at the bottom of the slope surface to ensure the protective effect of the retaining wall 1.

[0046] In addition, in order to further protect the slope surface, the present invention provides a water diversion platform 4 at the end of the water diversion channel 3 away from the retaining wall 1, and the water diversion platform 4 is arranged on the top of the slope surface. The interior of the water diversion platform 4 is connected with the interior of the water diversion channel 3. The arrangement of the water diversion channel 3 and the water diversion platform 4 can guide the water flow flowing into the slope surface, reduce soil erosion, and prevent the influence of heavy rain and continuous long-term rainfall on the stability of the slope surface.

[0047] In this embodiment, a retaining wall reinforcement component 5 for reinforcing the retaining wall 1 is provided on one side of the retaining wall 1 away from the water diversion channel 3. The water flow guided by the water diversion platform 4 and the water diversion channel 3 flows into the retaining wall reinforcement component 5 to increase the weight of the retaining wall reinforcement component 5. Specifically, Figure 2 and 5-8, the retaining wall reinforcement assembly 5 includes two triangular reinforcement boxes a51, the triangular reinforcement box a51 is arranged on the side of the retaining wall 1 away from the water diversion channel 3, and two triangular reinforcement boxes b52 are arranged between the two triangular reinforcement boxes a51. A water diversion channel connecting pipe 513 is fixed between the retaining wall 1 and the triangular reinforcement box a51. The water diversion channel connecting pipe 513 penetrates the retaining wall 1 and the side walls of the triangular reinforcement box a51 and extends into the interior of the triangular reinforcement box a51. One end of the water diversion channel connecting pipe 513 is connected to the interior of the water diversion channel 3, and is used to introduce the water flow guided by the water diversion platform 4 and the water diversion channel 3 into the interior of the triangular reinforcement box a51, so as to increase the weight of the triangular reinforcement box a51; there is a reinforcement fixedly connected between the triangular reinforcement box a51 and the triangular reinforcement box b52. The box connecting pipe 53 has an electromagnetic valve 54 fixed on the outer end thereof, which is used to introduce the water flow inside the triangular reinforcement box a51 into the triangular reinforcement box b52 to increase the weight of the triangular reinforcement box b52. The cross-sections of the triangular reinforcement box a51 and the triangular reinforcement box b52 in the present invention are both set to be right-angled triangles, and the stability of the triangle is utilized to enable them to support the retaining wall 1. At the same time, the water flow drained from the water diversion platform 4 and the water diversion channel 3 can be used to increase the dead weight of the triangular reinforcement box a51 and the triangular reinforcement box b52, thereby further increasing the supporting force applied by the triangular reinforcement box a51 and the triangular reinforcement box b52 on the retaining wall 1, improving the reinforcement effect of the retaining wall 1, and making the water flow under the diversion also play a role, killing two birds with one stone.

[0048] like Figure 7 As shown, a plurality of drainage holes 55 connected to the interior of the triangular reinforcement box b52 are provided at the top thereof. If the amount of water drained by the water diversion platform 4 and the water diversion channel 3 due to heavy rain or long-term continuous rainfall exceeds the amount that can be accommodated inside the triangular reinforcement box a51 and the triangular reinforcement box b52, the water flow can be discharged through the drainage holes 55 on the top of the triangular reinforcement box b52 to ensure normal drainage.

[0049] In this embodiment, the number of the reinforcement box connecting pipes 53 is set to two, and a solenoid valve 54 is fixed to the outer end of each reinforcement box connecting pipe 53. A control mechanism for controlling the opening and closing of the solenoid valve 54 is provided on the top of the triangular reinforcement box a51. The control mechanism is used to control the solenoid valve 54 to open only after the water flow inside the triangular reinforcement box a51 is full, so as to introduce excess water into the interior of the triangular reinforcement box b52;

[0050] The specific structure of the control mechanism is as follows Figure 6As shown, the control mechanism includes a control box 56 fixed in the middle of the top of the triangular reinforcement box a51, a vent hole 512 is provided on one side of the control box 56, and the vent hole 512 connects the inside of the control box 56 with the outside world, and a water hole 57 for connecting the control box 56 is provided inside the triangular reinforcement box a51, and a piston plate 58 is provided at the bottom end of the control box 56, and the cross-sectional shape of the piston plate 58 and the cross-sectional shape of the inner cavity of the control box 56 are both circular, and a short rod 59 and a spring 511 are fixed to the top of the piston plate 58, and the short rod 59 is located inside the spring 511, and the short rod 59 The top is fixed to the top of the inner cavity of the control box 56. A touch switch 510 for controlling the opening and closing of the electromagnetic valve 54 is provided at the top of the inner cavity of the control box 56. When the water discharged from the water diversion channel 3 and the water diversion platform 4 fills the interior of the triangular reinforcement box a51, the water inside the triangular reinforcement box a51 will enter the interior of the control box 56 through the water hole 57, and simultaneously push the piston plate 58 to drive the short rod 59 to move up until the short rod 59 contacts the touch switch 510, and then the electromagnetic valve 54 is opened, so that the water flowing into the interior of the triangular reinforcement box a51 can enter the interior of the triangular reinforcement box b52 through the reinforcement box connecting pipe 53. When there is no water or the water is not full inside the triangular reinforcement box a51, the piston plate 58 will be located at the bottom of the inner cavity of the control box 56 under the elastic force of the spring 511, so that the short rod 59 is away from the touch switch 510, and the control electromagnetic valve 54 is in a closed state.

[0051] It is worth emphasizing that the touch switch 510 used in the present invention is a normally open touch switch, which connects the circuit when pressed and disconnects the circuit when released; the solenoid valve 54 uses a 2W-F straight-pull diaphragm flange solenoid valve, which is suitable for water or liquid as the working medium, and can automatically control or remotely control the on and off of water, oil, liquid and other working medium pipelines.

[0052] The circuit where the touch switch 510 and the solenoid valve 54 are located in the present invention also includes a PLC for controlling the reinforcement box connecting pipe 53. The PLC is a digital operation electronic system specially designed for use in an industrial environment. It uses a programmable memory to store instructions for performing operations such as logical operations, sequential control, timing, counting and arithmetic operations, and controls various types of machinery or production processes through digital and analog inputs and outputs. It is known that using PLC to control valve switches is a commonly used technical means in the prior art, so the present invention will not be further described here.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
