Abstract

This invention relates to the field of high slope protection technology, and provides a prefabricated high slope anti-slip device and protection method. The anti-slip device includes a high slope, a fixing frame, and a base. A fixing frame is placed on the slope surface of the high slope. Multiple connecting plates, evenly spaced vertically, are fixedly connected along the length of the fixing frame. A row of positioning cones inserted into the slope surface are fixedly connected to the bottom of each connecting plate. The fixing frame is fixedly connected to the top horizontal surface of the high slope. The fixing frame of this invention can form a fixed position on the high slope surface, preventing the slope surface from sliding down and deforming. Since the connecting base is located on the front of the high slope, if the soil on the front of the high slope is unstable and deforms forward, the connecting base can block and limit the soil movement on the front of the high slope, preventing the slope from collapsing and causing the slope to collapse. This achieves the purpose of providing all-round anti-slip protection for the high slope.

Description

Technical Field

[0001] This invention belongs to the field of high slope protection technology, and more specifically, relates to a prefabricated high slope anti-slip device and protection method. Background Technology

[0002] High slopes refer to artificial slopes and natural slopes that affect the safety or stability of buildings, either formed by the excavation or filling of buildings or municipal engineering projects at or around the site of a building.

[0003] For high slopes, landslide prevention measures should be taken. The factors affecting slope stability mainly include two aspects: internal factors and external factors. Internal factors include the physical properties, geological structure, rock mass structure and geostress of the rock mass that makes up the high slope, and internal factors often play a major controlling role. External factors include the effects of surface water and groundwater, earthquakes, wind erosion, artificial excavation and engineering loads, among which surface water and groundwater are the most important and active external factors affecting slope stability.

[0004] In existing technologies, to prevent landslides on high slopes, multiple protective plates are laid on the slope surface. These plates form a protective layer to prevent landslides caused by slope instability. However, this method mainly focuses on pressing down and shaping the sloping surface. Even if the slope does not extend outwards, the front side (non-sloping side) may still collapse directly towards the ground. In this case, the slope will collapse directly downwards, and traditional guardrails cannot prevent landslides. Therefore, it is necessary to design a prefabricated high slope anti-slip device to solve this problem.

[0005] A search revealed several patents related to slope protection devices. For example, Chinese patent application number 201822092990.2, filed on December 13, 2018, entitled "An Anti-slip Device for Highway Slopes," includes a protective frame comprising a top beam, a bottom beam, and two side beams. The top and bottom beams are connected at both ends by the two side beams. Multiple fastening blocks are installed on the top and bottom beams. Multiple horizontal reinforcing plates connect the two side beams, and vertical reinforcing plates connect the horizontal reinforcing plates. The horizontal and vertical reinforcing plates and the protective frame together form multiple protective zones, each containing a protective component. The protective component includes a protective skeleton and a protective net. The protective net is located at the bottom of the protective skeleton. Multiple support rods are installed inside the protective skeleton, and a water channel is opened on the upper surface of each support rod. The water channels of two adjacent protective components are connected through a first water guide channel.

[0006] The modular protective device designed in this application first forms a protective zone by assembling multiple horizontal and vertical reinforcing plates and a protective frame. Then, a protective skeleton is installed within the protective zone, and finally, a protective net is installed inside the skeleton. Its structural design is relatively complex and installation is cumbersome. Furthermore, the device's compressive effect on the entire slope needs improvement, resulting in poor overall protection. Especially when landslides occur due to slope deformation, the entire anti-slide device is prone to sliding off the slope, and its stability needs further enhancement. Summary of the Invention

[0007] 1. The problem to be solved

[0008] To address the shortcomings of existing high slope protection technologies mentioned above, this invention provides a prefabricated high slope anti-slip device and protection method. The device of this invention effectively protects the slope surface and inhibits slope deformation. It is also resistant to slippage during long-term use. Furthermore, the anti-slip device of this invention has a simple structure, is easy to use, and is low in cost.

[0009] 2. Technical Solution

[0010] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0011] The present invention provides an assembled high slope anti-slip device, comprising a fixing frame, a fixing base, a connecting seat, and an elastic element;

[0012] A fixed frame is placed on the slope surface of the high slope, and a protective component is installed inside the fixed frame. To improve the protective effect, the protective component in this invention adopts a connecting plate and a positioning cone. Multiple connecting plates are fixedly connected along the length of the fixed frame, and a row of positioning cones inserted into the slope surface are fixedly connected to the bottom of each connecting plate. By optimizing the structure of the protective component, the slope surface is compressed and limited, thereby significantly reducing the phenomenon of slope landslide.

[0013] The fixing frame is fixedly connected to the horizontal surface at the top of the high slope, and the front of the fixing frame is connected to the top of the fixing frame through a traction component. More optimized, the traction component uses multiple traction ropes to achieve the installation connection between the fixing frame and the fixing frame, which is convenient to install and operate and has low cost.

[0014] Meanwhile, in order to further improve the pressing and limiting effect of the anti-slip device on the slope, the present invention fixes the base to the ground and is located on the front of the high slope. The top of the base is equipped with a connecting seat with an open top. The bottom of the fixing frame is fixedly connected to the top side of the connecting seat. A row of vertically oriented mounting rods is inserted through the bottom of the inner wall of the connecting seat and is detachably fixed to the top of the base. Each mounting rod is equipped with an elastic element that can always press the connecting seat downward.

[0015] As a further preferred embodiment of the present invention, each mounting rod has an external thread at the bottom of its circumferential surface, a row of holes is provided at the bottom of the connecting seat, a row of threaded grooves is provided on the base, and the bottom of each mounting rod passes through the connecting seat through the holes and is inserted into the corresponding threaded groove through the engagement of the external thread, so that the mounting rod can form a detachable fixed connection on the base.

[0016] As a further preferred embodiment of the present invention, a limiting block with a diameter larger than that of the mounting rod is fixedly connected to the top of the mounting rod. The elastic element includes a large industrial spring sleeved on the mounting rod and located between the inner wall of the connecting seat and the bottom surface of the limiting block. The large industrial spring will press the connecting seat towards the base through its own elasticity. The connecting seat can drive the fixing frame to press the fixing frame tightly on the slope surface of the high slope, so as to limit the deformation of the slope surface.

[0017] As a further preferred embodiment of the present invention, the top of the limiting block is provided with a hexagonal groove, and a hexagonal wrench can be used to rotate the limiting block to facilitate the disassembly and assembly of the mounting rod.

[0018] As a further preferred embodiment of the present invention, a cover plate is fitted onto the top of the connector to seal the opening at the top of the connector, so as to prevent rainwater from entering the interior of the connector.

[0019] As a further preferred embodiment of the present invention, both sides of the fixing frame are fixedly connected with vertically oriented fixing steel bars, and the bottom of the two fixing steel bars are fixedly inserted into the horizontal surface at the top of the high slope, so that the fixing frame can be fixed on the high slope.

[0020] As a further preferred embodiment of the present invention, there is at least a three-meter gap between the connection point of the bottom of the two fixed steel bars and the top surface of the high slope and the slope surface, so as to prevent the fixed steel bars from tilting along with the slope deformation when the slope surface of the high slope is deformed, and causing the top of the fixed frame to lose its support point.

[0021] As a further preferred embodiment of the present invention, the length of the fixing frame is the same as the length of the high slope surface, and the width of the fixing frame is 4-6 meters, so as to ensure that the fixing frame can effectively prevent slippage on the high slope surface.

[0022] As a further preferred embodiment of the present invention, an angle α is formed between the surface of the fixed frame and the traction rope, where α > 150° and α < 180°, so that the traction rope fixed to the surface of the fixed frame can effectively pull the top of the fixed frame towards the slope surface of the high slope.

[0023] As a further preferred embodiment of the present invention, the fixed frame is internally fixedly connected with a plurality of reinforcing plates that are equally spaced and perpendicular to the connecting plate, so that the fixed frame has sufficient strength to limit the deformation and landslide of the high slope surface and achieve excellent protection effect.

[0024] The present invention provides a method for protecting high slopes, which uses the protective device of the present invention to protect high slopes, specifically including the following steps:

[0025] Step 1: Determine the size and quantity of anti-skid device components based on the terrain characteristics of the high slope;

[0026] Step 2: Install and fix the anti-slip device on the slope surface of the high slope. When installing the fixing frame, ensure that the included angle α between the surface of the fixing frame and the traction rope is greater than 150° and less than 180°; the fixing steel bar installation points on both sides of the fixing frame are at least three meters away from the slope surface of the high slope.

[0027] 3. Beneficial effects

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] The anti-slip device of the present invention can be fixed on the slope surface of a high slope by setting a fixed frame, which can prevent the slope surface of the high slope from sliding down and deforming. Furthermore, since multiple positioning cones on the fixed frame are inserted into the slope surface of the high slope, the positioning cones can block the movement of the soil structure within the slope surface, thereby reducing changes in the soil structure inside the high slope.

[0030] Meanwhile, since the anti-slip device of the present invention has a connecting seat that is located on the front of the high slope, if the soil on the front of the high slope is unstable and deforms forward, the connecting seat can block and limit the soil deformation on the front of the high slope, thus preventing the slope from collapsing and causing the slope to fall. When the anti-slip device of the present invention is used to protect the high slope, it can achieve the purpose of providing all-round anti-slip protection for the high slope.

[0040] Obviously, many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0041] Example 1

[0042] This embodiment of a prefabricated high slope anti-slip device includes a fixing frame 6, a fixing frame 2, a base 8, a connecting seat 9, and an elastic element 11. The fixing frame 6 is located at the top of the high slope 1 and is connected to the fixing frame 2 via a traction member. The fixing frame 2 is placed on the slope surface of the high slope 1, and a protective component is installed inside the fixing frame 2. The base 8 is fixedly installed on the ground and is connected to the fixing frame 2 via the connecting seat 9. An elastic element 11 is installed at the connection point between the connecting seat 9 and the base 8, and this elastic element 11 is used to pull the connecting seat 9 towards the base 8.

[0043] Specifically, such as Figure 1-3 As shown, the fixing frame 6 is fixedly connected to the top horizontal surface of the high slope 1, and the traction component fixedly connected between the front of the fixing frame 6 and the top of the fixing frame 2 can use existing connecting components, mainly serving a connecting function, so that the fixing frame 2 as a whole can form an effective fixation on the slope surface of the high slope 1, thereby improving the protective effect of the fixing frame on the slope surface. As a preferred embodiment, the traction component of this embodiment consists of multiple spaced traction ropes 7, with both ends of the traction ropes 7 fixedly connected to the fixing frame 6 and the fixing frame 2 respectively. The structure is simple, easy to install, and has low manufacturing cost.

[0044] In addition, to further ensure the installation effect, the multiple traction ropes 7 in this embodiment are evenly distributed to form a reliable and stable tension between the fixed frame 6 and the fixed frame 2.

[0045] In addition, the length of the fixed frame 2 is the same as the length of the slope 1 (that is, the distance from the top to the bottom of the slope), and the width of the fixed frame 2 is 4-6 meters to ensure that the fixed frame 2 can effectively prevent the slope 1 from slipping. At the same time, if the slope 1 is wide, multiple such devices can be set up for slope prevention treatment, and there should be a gap of about two meters between each fixed frame 2.

[0046] See Figure 4 An angle α is formed between the surface of the fixed frame 2 and the traction rope 7, where α > 150° and α < 180°, so that the traction rope 7 fixed to the surface of the fixed frame 6 can pull the top of the fixed frame 2 toward the slope surface of the high slope 1, so as to ensure that the top of the fixed frame 2 can be in close contact with the slope surface of the high slope 1 and prevent the slope surface from deforming.

[0047] like Figure 1 and Figure 2 As shown, the base 8 is fixedly connected to the ground and located on the front of the high slope 1. A connecting seat 9 with an open top is placed on top of the base 8; that is, the connecting seat 9 is processed into an open box structure to facilitate subsequent installation. The bottom of the fixing frame 2 is fixedly connected to one side of the top of the connecting seat 9, and also includes a mounting rod 10, as shown... Figure 5-7 As shown, a row of vertically oriented mounting rods 10 are inserted into the bottom of the inner wall of the connecting seat 9 and are detachably fixed to the top of the base 8. Each mounting rod 10 is equipped with an elastic element 11 that can always press the connecting seat 9 downward. Through this design, the fixing frame 2 can be fixed on the slope surface of the high slope 1, which can prevent the slope surface of the high slope 1 from sliding down and deforming. Since multiple positioning cones 4 on the fixing frame 2 are inserted into the slope surface of the high slope 1, the positioning cones 4 can block the movement of the soil structure in the slope surface, reduce the change of the soil structure inside the high slope 1. At the same time, since the connecting seat 9 is located on the front of the high slope 1, if the soil on the front of the high slope 1 is unstable and deforms forward, the connecting seat 9 can block and limit the change of the soil on the front of the high slope 1, avoid the problem of the slope surface collapsing due to the front of the high slope 1, and thus achieve the purpose of providing all-round anti-slip protection for the high slope 1.

[0048] Even better, the base 8 has an L-shaped structure, so that when the high slope 1 collapses, the base 8 can also support the front of the connecting seat 9 and the high slope 1 to improve stability.

[0049] As a further improvement to this embodiment, such as Figure 5 and Figure 6As shown, the specific connection method between the mounting rod 10 and the base 8 is as follows: each mounting rod 10 has an external thread 13 at the bottom of its circumferential surface, the bottom of the connecting seat 9 has a row of holes, and the base 8 has a row of threaded grooves 12. The bottom of each mounting rod 10 passes through the holes of the connecting seat 9 and is inserted into the corresponding threaded groove 12 through the engagement of the external thread 13, so that the mounting rod 10 can form a detachable fixed connection on the base 8. This design is more reasonable.

[0050] Furthermore, in order to keep the connecting seat 9 pressed downwards at all times, some embodiments propose that a limiting block 14 with a diameter larger than that of the mounting rod 10 be fixedly connected to the top of the mounting rod 10. The elastic element 11 includes a large industrial spring sleeved on the mounting rod 10 and located between the inner wall of the connecting seat 9 and the bottom surface of the limiting block 14. Since the mounting rod 10 and the limiting block 14 are fixed to the base 8, the large industrial spring is compressed as a whole in the inner cavity of the connecting seat 9. The large industrial spring will press the connecting seat 9 towards the base 8 through its own elasticity. The connecting seat 9 can then drive the fixing frame 2 to press the fixing frame 2 tightly on the slope surface of the high slope 1, thereby limiting the deformation of the slope surface.

[0051] Furthermore, there are even more optimized ones, such as Figure 7 As shown, the top of the limiting block 14 is provided with a hexagonal groove, and a hexagonal wrench can be used to rotate the limiting block 14 to facilitate the disassembly and assembly of the mounting rod 10.

[0052] like Figure 6 As shown, a cover plate 15 is fitted on the top of the connector 9 to seal the top opening (i.e., the vent) of the connector 9, so as to prevent rainwater from entering the interior of the connector 9 and causing the surface of the mounting rod 10 and the elastic element 11 to be soaked and corroded by rainwater.

[0053] As a further improvement to this embodiment, the protective component installed within the fixed frame 2 can be composed of existing protective netting or a protective frame, serving to fix and limit the slope surface, preventing deformation caused by internal or external interference factors. Furthermore, to significantly improve the protective effect of the anti-slip device, the protective component includes multiple connecting plates 3, to... Figure 1 and Figure 3 Taking the orientation in the middle as an example, the fixed frame 2 has multiple connecting plates 3 that are distributed vertically and horizontally along its length. The bottom of each connecting plate 3 is fixedly connected to a row of positioning cones 4 that are inserted into the slope surface of the high slope 1.

[0054] In a more optimized configuration, multiple connecting plates 3 and multiple positioning cones 4 are evenly spaced. That is, the multiple connecting plates 3 are perpendicular to the length direction of the fixed frame 2 from the top of the slope to the bottom of the slope and are evenly distributed. The multiple positioning cones 4 are evenly distributed along the length direction of the connecting plates 3.

[0055] Furthermore, the fixed frame 2 has multiple reinforcing plates 5 that are evenly spaced and perpendicular to the connecting plate 3. The reinforcing plates 5 can enhance the overall strength of the fixed frame 2 and the connecting plate 3, so that the fixed frame 2 has sufficient strength to limit the deformation and landslide of the high slope 1. This design is more reasonable.

[0056] As a further improvement to this embodiment, the specific connection method between the fixing frame 6 and the high slope 1 is as follows: Vertically oriented fixing steel bars 16 are fixedly connected to both sides of the fixing frame 6. The bottoms of both fixing steel bars 16 are fixedly inserted into the top horizontal surface of the high slope 1, allowing the fixing frame 6 to be fixed on the high slope 1. It should be noted that there is at least a three-meter gap between the connection point between the bottom of the two fixing steel bars 16 and the top surface of the high slope 1 and the slope surface of the high slope 1. This is to prevent the fixing steel bars 16 from tilting due to slope deformation when the slope surface of the high slope 1 deforms, thus preventing the top of the fixing frame 2 from losing its support point.

[0057] The present invention provides a method for protecting high slopes, which uses the anti-slip device of the present invention for protection, and mainly includes the following steps:

[0058] Step 1: Determine the size and quantity of anti-skid components based on the terrain characteristics of high slope 1;

[0059] Step 2: Install and fix anti-slip devices on the slope surface of high slope 1;

[0060] When installing the fixing frame 6, the included angle α between the surface of the fixing frame 2 and the traction rope 7 must be greater than 150° and less than 180°; the installation points of the fixing steel bars 16 on both sides of the fixing frame 6 must be at least three meters away from the slope surface of the high slope 1.

[0061] It should be noted that in the description of this invention, the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0062] Furthermore, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "setting," "connection," "fixing," "screw connection," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.
