Description

Technical Field

[0001] This invention relates to the field of slope reinforcement technology, specifically to an active reinforcement system for high slope rock masses. Background Technology

[0002] High slopes refer to soil slopes with a height greater than 20m and less than 100m, or rock slopes with a height greater than 30m and less than 100m. To prevent landslides and collapses, slopes need to be reinforced and protected.

[0003] A search revealed that patent number CN215252947U discloses a slope reinforcement and anti-collapse structure for rock and soil. This reinforcement structure, through the action of a drive motor, a drive gear, a driven gear, a threaded rod, and a threaded sleeve, can adjust the slope anti-collapse mechanism to accommodate slopes of various angles. With the action of a buffer mechanism, a reinforcing rod, a slider, and a spring, it can minimize wear between the structural components of the anti-collapse mechanism, reduce wear on parts between the components, and increase the service life of the slope anti-collapse mechanism. With the action of a hydraulic rod, a connecting plate, and casters, the anti-collapse structure can be easily moved.

[0004] However, the above-mentioned reinforcement structure requires electric motors for electric drive reinforcement. When there are multiple slopes, multiple reinforcement structures need to be placed, requiring multiple motors to work together, which consumes a lot of resources, and the installation of the reinforcement structure is not convenient. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an active reinforcement system for high slope rock masses. This system can quickly reinforce the slope surface, and the reinforcement structure is easy to assemble and disassemble, improving the convenience of reinforcement operations. It solves the problem of needing to use electric motors for electric drive reinforcement, and when there are multiple slope surfaces, multiple reinforcement structures need to be placed, requiring multiple motors to work together, which consumes a lot of resources.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an active reinforcement system for high slope rock mass, comprising multiple positioning columns set on the slope, the positioning columns being arranged in a Y-shape and inserted into the slope, a sleeve being fixedly provided on the upper end of one side of the positioning column, a sleeve rod being slidably inserted inside the sleeve, and an adjustment positioning mechanism being provided between the sleeve rod and the sleeve to limit the distance between the sleeve rod and the sleeve, which can adjust the distance between the sleeve rod and the sleeve according to the slope structure;

A first connecting hole is opened inside each of the two connecting blocks. Two reinforcing protective nets are provided between the two connecting blocks in the longitudinal direction. Multiple reinforcing rods are fixedly provided on the side of the reinforcing protective nets near the slope. The ends of the reinforcing rods are inserted into the slope. Through the protection of the reinforcing protective nets and the reinforcing rods, the slope can be effectively reinforced and protected.

[0008] The reinforced protective net has a second connecting hole on each side. A limiting connecting mechanism for connecting the reinforced protective net is provided between the second connecting hole and the connecting block, which enables the reinforced protective net to be quickly installed and disassembled.

One end of the first spring is fixedly connected to the inner wall of the groove, and the other end of the first spring is fixedly connected to one end of the positioning rod. The rod wall of the positioning rod slides in contact with the inner wall of the groove, and the other end extends out of the sleeve and outward. The outer wall of the sleeve near the positioning rod has a plurality of spaced positioning holes. The positioning rod is inserted into the positioning holes. By inserting the positioning rod into the positioning holes at different positions, the distance between the sleeve and the sleeve rod can be quickly adjusted.

[0010] Preferably, the cross-sections of the sleeve and the rod are both rectangular, so that the sleeve and the rod can only slide in one direction.

[0018] (III) Beneficial Effects

[0019] Compared with existing technologies, this invention provides an active slope reinforcement system for high rock masses, which has the following beneficial effects:

[0020] 1. This high slope rock mass active reinforcement system uses positioning columns inserted into the slope, and the slope is covered and protected by the reinforcement net and the connection between the reinforcement rod and the positioning column, so as to actively reinforce the slope and minimize the occurrence of landslides and collapses.

[0021] 2. This high slope rock mass active reinforcement system, through the provided sleeves, rods, connecting blocks, as well as adjustment and positioning mechanisms, limit connection mechanisms, and snap-fit ​​mechanisms, can quickly connect the internal components of the reinforcement structure, improve the convenience of reinforcement structure installation, and facilitate disassembly and replacement.

[0022] 3. This high slope rock mass active reinforcement system uses a combination structure of socket and mounting body for the positioning columns. The top of the socket is redefined as a horizontal reference plate. The horizontal reference plate of two adjacent positioning columns facilitates the installation of the reinforcement netting and ensures the tilt angle of the two reinforcement nettings. The reinforcement netting with a certain tilt angle ensures that the reinforcement rod is inserted into the corresponding slope position, thereby ensuring the stability of the high slope structure. Since the tilt angle of the reinforcement netting is greater than the slope angle, the reinforcement depth of the reinforcement rod gradually increases with the anchoring depth near the bottom of the slope, greatly improving the reinforcement and protection of the slope and further ensuring its structural stability and reliability.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] Please see Figure 1-2 The high slope rock mass active reinforcement system includes multiple positioning columns 1 set on the slope. The positioning columns 1 are Y-shaped and the bottom of each positioning column 1 is conical. The positioning columns 1 are inserted into the slope and connected to the slope by mortar, so that the positioning columns 1 can be stably inserted into the slope and the position of the positioning columns 1 is fixed.

[0034] Please see Figure 2 and Figure 4 A sleeve 2 is fixedly installed on the upper end of one side of the positioning column 1. A sleeve rod 3 is slidably inserted inside the sleeve 2. A connecting block 4 is fixedly installed on the upper end of the other side of the positioning column 1 and the end of the sleeve rod 3. A first connecting hole is opened inside the two connecting blocks 4. Two reinforcing protective nets 5 are provided between the two connecting blocks 4 in the longitudinal direction. Multiple reinforcing rods 6 are fixedly installed on the side of the reinforcing protective net 5 near the slope. The slope is covered and protected by the reinforcing rods 6 and the reinforcing protective net 5 to avoid the slope from landslide and collapse as much as possible.

[0035] Please see Figure 1 The ends of the reinforcing rods 6 are inserted into the slope. All reinforcing rods 6 are steel rods, and the reinforcing protective net 5 is a steel mesh. All reinforcing rods 6 are fixedly connected to the reinforcing protective net 5 by welding. The surfaces of the reinforcing protective net 5 and the reinforcing rods 6 are coated with anti-rust paint. The reinforcing rods 6 and the reinforcing protective net 5 have sufficient strength and service life, thus providing stable support and reinforcement for the slope.

[0036] Example 2

[0037] Example 2 is based on Example 1. Please refer to Example 1. Figure 2 and 4 An adjustment and positioning mechanism is provided between the sleeve rod 3 and the sleeve 2 to limit the distance between the sleeve rod 3 and the sleeve 2. The cross-sections of the sleeve 2 and the sleeve rod 3 are both rectangular, so that the sleeve rod 3 and the sleeve 2 can only slide in one direction.

[0038] Please see Figure 4 The adjusting positioning mechanism includes a positioning rod 7 and a first spring 8. A groove is provided on the outer wall of the sleeve rod 3. One end of the first spring 8 is fixedly connected to the inner wall of the groove, and the other end of the first spring 8 is fixedly connected to one end of the positioning rod 7. The rod wall of the positioning rod 7 slides in contact with the inner wall of the groove, and the other end passes through the sleeve 2 and extends to the outside. A plurality of spaced positioning holes are provided on the outer wall of the sleeve 2 near the positioning rod 7. The positioning rod 7 is inserted into the positioning holes. By inserting the positioning rod 7 into the positioning holes at different positions, the distance between the sleeve 2 and the sleeve rod 3 can be adjusted, so that the reinforced protective net 5 can be installed at different angles according to the slope inclination angle, thereby effectively reinforcing slopes of various shapes.

[0039] Example 3

[0040] Example 3 is based on Examples 1-2. Please refer to Example 3. Figure 2 and Figure 5 The reinforced protective net 5 has a second connecting hole on both sides. A limiting connecting mechanism for connecting the reinforced protective net 5 is provided between the second connecting hole and the connecting block 4. The limiting connecting mechanism includes two circular plates 9 and a pin 10. The centers of the first connecting hole and the second connecting hole are on the same horizontal line. The pin 10 is inserted into the first connecting hole and the second connecting hole. The two circular plates 9 are respectively slidably sleeved on the outer ends of the pin 10. The reinforced protective net 5 and the connecting block 4 can be connected by inserting the pin 10 into the first connecting hole and the second connecting hole.

[0041] Please see Figure 3The two circular plates 9 are connected to the reinforced protective net 5 and the connecting block 4 on opposite sides, respectively. The top two ends of the pin 10 are provided with moving grooves. The ends of the positioning rod 7 and the pin 10 are both hemispherical. The pin 10 can be quickly pulled out to complete the disassembly of the reinforced protective net 5.

[0042] Please see Figure 3 Both movable slots are equipped with locking mechanisms for limiting the position of the circular plate 9. The locking mechanism includes a locking rod 11 and a second spring 12. A telescopic rod 13 is fixedly installed on the inner wall of the movable slot. The locking rod 11 is fixedly connected to the top of the telescopic rod 13. The second spring 12 is sleeved on the sleeve end of the telescopic rod 13, and its two ends are fixedly connected to the sleeve ends of the locking rod 11 and the telescopic rod 13, respectively. The top of the locking rod 11 extends out of the movable slot and contacts the circular plate 9. When the circular plate 9 is sleeved on both ends of the pin rod 10, the locking rod 11 locks the circular plate 9 to the outside, fixing the position of the circular plate 9. This makes the reinforced protective net 5 connected and fixed to the connecting block 4, improving the stability of the reinforced protective net 5 in use.

[0043] Example 4 is based on Examples 1-3. Please refer to Example 4. Figure 6 and Figure 7 The positioning post 10 includes an installation body 101 for connecting the sleeve 2 and the connecting block 4, and a socket body 102 inserted into the slope. The socket body 102 and the installation body 101 are connected by three equally spaced circumferentially distributed horizontal state-maintaining structures. The horizontal state-maintaining structure includes a rotating shaft 105 installed on the top of the socket body 102 and a connecting body 103 installed at the bottom center of the installation body 101. The two ends of the rotating shaft 105 are connected to the connecting rod 106 by pins. The end of the connecting rod 106 away from the rotating shaft 105 is connected to the rotating shaft 107 by pins. The three rotating shafts 107 are rotatably installed on the same positioning body 104. The positioning body 104 is provided with through holes for the connecting body 103 to be inserted and fixed. The socket 102 is inserted into the slope beforehand. After insertion, the positioning body 104 on it will be appropriately offset in height and displacement under the combined action of the connecting rod 106, the first rotating shaft 105, and the second rotating shaft 107. This is used to correct the levelness of the top of the socket 102 after it is inserted into the slope and the verticality of the socket 102. The positioning body 104, which is in a redefined horizontal reference state, is used as the levelness of the sleeve 2 and the connecting block 4. This makes it easier to ensure the rated tilt angle of the reinforced protective net 5 and the combined connection of the reinforced protective net 5, the sleeve 2, and the connecting block 4.
