Description

Technical Field

[0001] The invention relates to the technical field of disaster prevention and control equipment, in particular to a landslide protection structure for geological disaster prevention and control. Background Art

[0002] Geological disasters refer to geological actions or phenomena caused by natural or human factors that cause losses to human life and property and damage to the environment. Currently, humans can only prevent geological disasters but cannot solve them fundamentally.

[0003] Geological disasters are the result of the interaction between humans and nature. At present, humans are unable to effectively solve the problem of geological disasters fundamentally. They can only reduce casualties and property losses through early warning. For example, the protective structures set up on the slopes on both sides of the highway. The existing equipment covers the slopes with a mesh structure, which can fix large fallen rocks. This equipment has a simple structure and has a certain protective effect, preventing large rolling rocks from falling and affecting traffic. However, it cannot withstand large-scale landslide disasters. Landslides in the entire area will not only directly damage the fixed anchor points of the protective equipment, but also destroy the single-layer barrier structure due to the weight of large pieces of earth and rocks. In addition, the large pieces of earth and rocks will gradually increase the power of the disaster with the slope of the slope.

[0004] To this end, technical personnel in this field have proposed a landslide protection structure for geological disaster prevention and control, and designed a device that can protect against area landslides, which is not easily lost due to the falling of individual anchor points. At the same time, it can slow down landslides and intercept loose soil and rocks. This device can be more effectively used in slope protection to ensure the safety of life and property.

[0015] Preferably, the top bearing of the fixed side plate is provided with a driving shaft adapted to the transmission belt, and the side of the covering mesh cover is fixedly provided with driving teeth adapted to the driving shaft, and the driving shaft drives the covering mesh cover to move by meshing with the driving teeth.

[0016] The present invention discloses a landslide protection structure for preventing and controlling geological disasters, which has the following beneficial effects:

[0017] The landslide protection structure for geological disaster prevention and control is an improvement on the simple blocking protection structure in the prior art. It not only uses the blocking structure to fix the soil and rocks on the slope, but also arranges graded blocking components at intervals along the slope. The blocking and the graded blocking components form a mutually pulling relationship, and the height of each graded blocking component gradually increases from high to low. When part of the soil and rocks on the slope slide down, the soil and rocks are intercepted by installing a bottom plate and a fixed side plate to avoid the accumulation of loose soil and rocks in the blocking to cause a large-scale landslide. In addition, a covering mesh cover is also provided in the graded blocking component, and the soil and rocks dropped into the graded blocking component touch the pressure-sensitive plate. Then, when the soil and rocks accumulate to a certain mass, the loose soil and rocks in the graded blocking component are fixed by the covering mesh cover to avoid further sliding. The subsequent sliding soil and rocks are again intercepted and fixed by the next row of graded blocking components, which can reduce the occurrence of landslide disasters caused by the accumulation of loose soil and rocks.

[0018] The landslide protection structure used for geological disaster prevention and control has a graded barrier component that is set up in multiple levels based on the barrier net. The structure gradually increases from top to bottom of the slope. Cement piles are pre-anchored in the slope, and the installation base plate is then anchored through the piles to increase the stability of the equipment installation. A barrier interval is formed between the fixed side plates fixed with the installation base plate as the installation surface and the installation base plate. Scattered soil and rocks are intercepted in the interval. After a certain amount of soil and rocks are intercepted in the upper-level graded barrier component, the subsequent sliding soil and rocks pass over the upper-level graded barrier component and are intercepted by the lower-level graded barrier component, thereby achieving a larger amount of interception protection and avoiding the problem of a large amount of loose soil and rocks accumulating to cause the collapse of a single barrier structure and lead to landslide disasters.

[0019] In order to prevent a large amount of soil and rock accumulated in the graded barrier assembly from sliding down together with subsequent soil and rock to cause a landslide disaster, the landslide protection structure for geological disaster prevention and control is provided with a covering mesh cover based on a fixed side plate. When soil and rock fall to one side of the fixed side plate, pressure is applied to the pressure-sensitive plate. The pressure is controlled by a transmission structure to advance the covering mesh cover, so that after the graded barrier assembly intercepts a certain amount of soil and rock, the graded barrier assembly covers and fixes the internal soil and rock through the covering mesh cover, thereby preventing the internally intercepted soil and rock from sliding down together with subsequent soil and rock to cause a landslide.

[0020] The landslide protection structure for geological disaster prevention and control has a pressure-sensitive plate hinged with a fixed side plate. When soil and rocks fall onto the pressure-sensitive plate, the angle of the pressure-sensitive plate changes due to the mass of the soil and rocks, and then a rack arranged on its side moves forward. The rack drives the rotating shaft to rotate through meshing, and the rotation of the rotating shaft drives the driving shaft through a transmission belt, and then the rotation and advancement of the coated mesh cover are quantitatively driven through meshing with the driving teeth. In order to enhance and quantify the pressure-sensitive effect of the pressure-sensitive plate, a second spring is arranged on the side of the pressure-sensitive plate to press against a telescopic rod, and the pressing force of the telescopic rod on the pressure-sensitive plate can be adjusted by adjusting the screw rod.

[0021] In the landslide protection structure for geological disaster prevention and control, when the pressure-sensitive plate rotates, the angle of the rack arranged on its side also changes. Therefore, if the rotating shaft and the fixed rack are fixed, continuous meshing transmission cannot be achieved. Therefore, the rack and the pressure-sensitive plate are connected in a hinged manner, and a first spring is arranged to press the rack tightly, so that the rack can not only adapt to the angle change according to the angle change, but also maintain the meshing transmission relationship between the two.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The embodiment of the present invention discloses a landslide protection structure for preventing and controlling geological disasters.

[0035] According to the attached Figure 1 As shown, it includes a barrier net 1 and graded barrier components 2, the barrier net 1 is arranged on the surface of the slope protection, and multiple groups of graded barrier components 2 are evenly arranged on the barrier net 1. The barrier net 1 structure is composed of flat thin plates, and the barrier net 1 structure is laid according to the shape of the slope protection to provide slope protection, and multiple graded barrier components 2 are connected to each other through the barrier net 1 to form a connected whole.

[0036] Anchor nails 3 are provided through the side of the installation base plate 201. The barrier net 1 has the same function as the metal wire of the existing barrier net 1 but has a slightly different structure. It has the same equipment as the existing barrier net 1 to cover the slope surface, which can prevent a small amount of rolling stones from falling. At the same time, the metal wire is replaced by a metal strip, which has a better supporting effect. Multiple graded barrier components 2 can be supported in series, and sporadic falling soil and rocks can be intercepted and collected through the graded barrier components 2, so as to avoid the accumulation of a large amount of soil and rocks in the barrier net 1 and eventually cause a landslide disaster. The graded barrier components 2 are installed on the slope surface through anchor nails 3.

[0037] According to the attached Figure 2As shown, the mounting base plate 201 is fixedly arranged on the side of the slope protection, the upper surface of the mounting base plate 201 is fixedly arranged with a fixed side plate 202, and a covering mesh cover 203 is arranged above the mounting base plate 201, and the covering mesh cover 203 is used to cover and fix part of the sliding soil and rocks, thereby reducing the amount of sliding soil and rocks.

[0038] The installation base plate 201 is fixed on the slope by means of anchor nails 3 and is fixed to the barrier net 1. A blocking interval is formed by the fixed side plates 202 on its sides. Falling soil and rocks are intercepted above the fixed side plates 202. In order to achieve a better use of the equipment, a covering mesh cover 203 is also provided through the fixed side plates 202. After a certain amount of soil and rocks have fallen and accumulated, the soil and rocks are wrapped by the covering mesh cover 203 to prevent a large amount of soil and rocks from sliding down and causing landslides.

[0039] The anchor nail 3 passes through one end of the installation base plate 201 and is provided with a foundation pile 4, which is arranged on the side of the slope protection. A drainage groove 5 is opened on the side of the fixed side plate 202. The foundation pile 4 is installed deep into the slope, which is conducive to the stable installation between the equipment and the slope. The drainage groove 5 is opened on the side of the fixed side plate 202 to pass the water in the soil and stone, avoiding the accumulation of a large amount of mass in a short time. Rainwater can flow out of the drainage groove 5 to dry the soil and stone.

[0040] According to the attached Figure 3-5 As shown, a slider 6 is fixedly connected to the top of the fixed side plate 202, and the covering mesh cover 203 is slidably set on the side of the fixed side plate 202 through the slider 6. The slider 6 is set at the top of the fixed side plate 202, and the covering mesh cover 203 is slidably installed through the slider 6 to ensure the stability of the covering mesh cover 203 when used.

[0041] The covering mesh cover 203 is an arc-shaped structure, and the end of the covering mesh cover 203 is fixedly connected with a buckle 7 adapted to the mounting base plate 201, and the side of the mounting base plate 201 is provided with a slot 8 adapted to the covering mesh cover 203, and the inner side of the slot 8 is provided with a block 9 corresponding to the buckle 7, and the end of the covering mesh cover 203 is provided with a buckle 7 for fastening the covering mesh cover 203 after closing, so as to prevent the covering mesh cover 203 from opening when soil and rocks pour down from above.

[0042] In addition, the mounting base plate 201 is provided with a clamping groove 8 and a clamping block 9 adapted to the clamping buckle 7 to cooperate with each other to limit the covering mesh cover 203 .

[0043] A pressure-sensitive plate 10 is hingedly provided on the side of the fixed side plate 202 near one end of the mounting base plate 201, and the pressure-sensitive plate 10 senses the amount of soil and rocks intercepted inside the graded barrier assembly 2, and controls the advancement of the covering mesh cover 203 accordingly.

[0044] According to the attached Figure 6-7As shown, a rack 11 is hingedly provided on the side of the pressure-sensitive plate 10, and one end of the rack 11 away from the pressure-sensitive plate 10 passes through the fixed side plate 202, and a rotating shaft 12 adapted to the rack 11 is provided on the inner bearing of the fixed side plate 202, and the rotating shaft 12 is transmission-connected to the covering mesh cover 203.

[0045] The pressure-sensitive plate 10 drives the rotating shaft 12 to rotate through the meshing of the rack 11 , and then drives the rotating shaft 12 to rotate and advance the covering mesh cover 203 .

[0046] A gear 13 adapted to the rack 11 is fixedly sleeved on the side of the rotating shaft 12, and a first spring 14 is arranged between the rack 11 and the pressure-sensitive plate 10. The rotating shaft 12 is meshed with the rack 11 through the gear 13, and the rack 11 and the gear 13 are meshed for transmission to ensure accurate control.

[0047] According to the attached Figure 8-9 As shown, a transmission belt 15 is provided on the side of the rotating shaft 12, and the transmission belt 15 extends away from one end of the rotating shaft 12 to the top of the fixed side plate 202. The rotation of the rotating shaft 12 is transmitted through the transmission belt 15, thereby driving the covering mesh cover 203 to rotate and cover around the rotation center.

[0048] A telescopic rod 16 is fixedly arranged between the pressure-sensitive plate 10 and the mounting base plate 201 , an adjustment block 17 is slidably engaged on the inner side of the telescopic rod 16 , and a second spring 18 adapted to the adjustment block 17 is arranged on the inner side of the telescopic rod 16 , and the telescopic rod 16 is tightly arranged between the pressure-sensitive plate 10 and the fixed side plate 202 through the second spring 18 .

[0049] The pressure-sensitive plate 10 and the mounting base plate 201 are balanced and supported by a telescopic rod 16 to control the amount of soil and rocks intercepted in the graded barrier assembly 2. In addition, a soft barrier structure is provided between the pressure-sensitive plate 10 and the mounting base plate 201 to prevent sporadic soil and rocks from falling into the gap and blocking the advancement movement of the pressure-sensitive plate 10.

[0050] An adjusting screw 19 is passed through the side of the pressure-sensitive plate 10 and the bearing is provided thereon. The adjusting screw 19 passes through the adjusting block 17 and is threadedly connected thereto. A limiting block 20 adapted to the telescopic rod 16 is fixedly provided on the side of the adjusting block 17 .

[0051] The position of the adjusting block 17 is adjusted by adjusting the rotation of the screw rod 19 , thereby controlling the elastic force of the second spring 18 on the telescopic rod 16 , thereby controlling the strength of the telescopic rod 16 on the pressure-sensitive plate 10 .

[0052] The top bearing of the fixed side plate 202 is provided with a driving shaft 21 adapted to the transmission belt 15, and the side of the covering mesh cover 203 is fixedly provided with driving teeth 22 adapted to the driving shaft 21. The driving shaft 21 drives the covering mesh cover 203 to move by meshing with the driving teeth 22.

[0053] The transmission belt 15 rotates synchronously with the rotating shaft 12 and drives the driving shaft 21 to rotate through meshing transmission, and then the meshing action between the driving shaft 21 and the driving teeth 22 is used to control the advance of the covering mesh cover 203 in a controllable manner.

[0054] The landslide protection structure for geological disaster prevention and control is an improvement on the simple barrier net 1 protection structure in the prior art. It not only uses the barrier net 1 structure to fix the soil and rocks on the slope, but also arranges graded barrier components 2 at intervals along the slope. The barrier net 1 and the graded barrier components 2 form a mutually pulling relationship, and the height of each graded barrier component 2 gradually increases from high to low. When part of the soil and rocks on the slope slide down, the soil and rocks are intercepted by installing a bottom plate 201 and a fixed side plate 202 to avoid the accumulation of loose soil and rocks in the barrier net 1 and causing a large-scale landslide. In addition, a covering mesh cover 203 is also provided in the graded barrier component 2. The soil and rocks that fall into the graded barrier component 2 touch the pressure-sensitive plate 10. When the soil and rocks accumulate to a certain mass, the loose soil and rocks in the graded barrier component 2 are fixed by the covering mesh cover 203 to avoid further sliding. The subsequent sliding soil and rocks are intercepted and fixed again by the next row of graded barrier components 2, which can reduce the occurrence of landslide disasters caused by the accumulation of loose soil and rocks.

[0055] The graded barrier components 2 are arranged in multiple levels based on the barrier net 1, and gradually increase in height from top to bottom according to the slope. Cement foundation piles 4 are pre-anchored in the slope, and then the installation base plate 201 is anchored through the foundation piles 4 to increase the stability of the equipment installation. A barrier interval is formed between the fixed side plates 202 fixed with the installation base plate 201 as the installation surface and the installation base plate 201. Sporadic falling soil and rocks are intercepted in this interval. After a certain amount of soil and rocks are intercepted in the upper-level graded barrier components 2, the subsequent sliding soil and rocks pass through the upper-level graded barrier components 2 and are intercepted by the lower-level graded barrier components 2, thereby achieving a larger amount of interception protection, and can avoid the problem of a large amount of loose soil and rocks accumulating to cause the collapse of the structure of the single barrier net 1 and lead to landslide disasters.

[0056] In order to prevent a large amount of soil and rocks accumulated in the graded barrier assembly 2 from sliding down together with subsequent soil and rocks and causing landslide disasters, a covering mesh cover 203 is provided based on the fixed side plate 202. When the soil and rocks fall to one side of the fixed side plate 202, pressure is applied to the pressure-sensitive plate 10. The pressure is controlled by the transmission structure to advance the covering mesh cover 203. After the graded barrier assembly 2 intercepts a certain amount of soil and rocks, the graded barrier assembly 2 covers and fixes the internal soil and rocks through the covering mesh cover 203, which can prevent the internally intercepted soil and rocks from sliding down together with subsequent soil and rocks and causing landslides.

[0057] The pressure-sensitive plate 10 is hinged to the fixed side plate 202. When soil and rocks fall onto the pressure-sensitive plate 10, the angle of the pressure-sensitive plate 10 changes due to the mass of the soil and rocks, and then the rack 11 arranged on its side advances. The rack 11 drives the rotating shaft 12 to rotate through the meshing action. The rotation of the rotating shaft 12 drives the driving shaft 21 through the transmission belt 15, and then the rotation and advancement of the coated mesh cover 203 are quantitatively driven through the meshing action with the driving teeth 22. In order to enhance and quantify the pressure-sensitive effect of the pressure-sensitive plate 10, a second spring 18 is also arranged on the side of the pressure-sensitive plate 10 to press against the telescopic rod 16, and the pressing force of the telescopic rod 16 on the pressure-sensitive plate 10 can be adjusted by adjusting the screw 19.

[0058] When the pressure-sensitive plate 10 rotates, the angle of the rack 11 arranged on its side also changes. Therefore, if the rotating shaft 12 and the rack 11 are fixedly arranged, they cannot continuously engage and transmit. Therefore, the rack 11 and the pressure-sensitive plate 10 are connected in a hinged manner, and a first spring 14 is arranged to press against the rack 11, so that the rack 11 can not only adaptably change its angle according to the angle change, but also maintain the meshing transmission relationship between the two.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
