Description

Technical Field

[0001] This invention relates to the field of barrier technology, and in particular to a debris flow barrier system that is easy to install and use. Background Technology

[0002] Debris flows are special types of torrents containing large amounts of solid materials such as mud, sand, and rocks, triggered by flash floods caused by heavy rainfall or snowmelt in mountain valleys. They are characterized by sudden eruptions, with turbid fluids rushing and roaring down steep gullies, causing ground tremors and a thunderous roar in the valley. In a very short time, they wash large amounts of mud, sand, and rocks out of the gully, cascading and depositing them in wide accumulation areas, often causing significant damage to human life and property. Debris flows are classified according to their gully morphology into valley-type and hillside-type debris flows.

[0003] Common engineering prevention and control measures for debris flow geological hazards mainly include two categories: diversion and containment. Diversion engineering aims to improve the flow potential of the debris flow, increase the drainage capacity of bridges and other structures, and ensure the debris flow is discharged smoothly according to design specifications. Diversion engineering includes diversion dikes, rapid flow channels, and constriction dikes. Containment engineering is used to control the solid material in the debris flow and the runoff from rainstorms and floods, weakening the flow rate, discharge volume, and energy of the debris flow to reduce the damage caused by scouring, impact, and burial of downstream structures. Containment measures include spoil dams, silt storage sites, retaining structures, and flood interception structures. Among these, permeable containment dams that block solid material in debris flows mainly include slotted dams, sieve dams, and grid dams.

[0004] The traditional method for installing retaining dams in gullies is as follows: first, several anchor holes are drilled at the corresponding locations in the gully, the rigid retaining structure of the retaining dam is suspended in the gully, and the installation of the rigid retaining structure in the gully is completed using anchor rods and anchor holes.

[0005] When drilling anchor holes, the complex terrain in the valley often results in uneven drilling surfaces, leading to inconsistent hole diameters. This is especially problematic when the hole diameter is much larger than the anchor bolt's outer diameter. Using the original anchor bolts cannot securely and effectively fix them in the large-diameter holes, affecting the stability of the retaining dam after installation. Replacing the anchor bolts with larger outer diameters also impacts installation efficiency and timeline. Summary of the Invention

[0006] To address the technical problems mentioned in the background section, this invention provides a debris flow barrier system that is easy to install and use.

[0007] The present invention is achieved by the following technical solution: a debris flow interception system that is easy to install and use, comprising at least one interception dam set sequentially in the valley along the flow direction and monitoring equipment set at the position corresponding to each of the interception dams, wherein the monitoring equipment is used to monitor the environmental information at the interception dam in real time;

[0008] Anchor holes corresponding to the location of the retaining dam are pre-drilled in the gully, and anchor rods that can be inserted into the anchor holes are installed on the retaining dam. A positioning device is installed in the anchor holes.

[0009] When the diameter of the anchor hole is larger than the outer diameter of the anchor rod, the positioning device is used to lock and fix the anchor rod in the corresponding anchor hole.

[0010] As a further improvement to the above solution, the positioning device includes a pre-installed cylinder, one end of which is closed and can be inserted into the anchor hole, and the other end has an opening for the anchor rod to be inserted. The pre-installed cylinder is provided with a diagonal bracing mechanism.

[0011] When the anchor rod is inserted into the pre-installed cylinder, the diagonal bracing mechanism is used to lock and fix the anchor hole and the pre-installed cylinder.

[0012] As a further improvement to the above solution, the diagonal bracing mechanism includes two rollers that are rotatably disposed opposite to each other along the axial direction of the pre-assembly cylinder and on the outer wall of the pre-assembly cylinder. Part of the roller body extends into the pre-assembly cylinder to contact the outer wall of the anchor rod inserted into the pre-assembly cylinder. A first diagonal bracing rod is fixed to the outer periphery of the roller. When the anchor rod is inserted into the pre-assembly cylinder, the end of the first diagonal bracing rod away from the roller rotates with the roller and extends out of the pre-assembly cylinder to press and contact the inner wall of the anchor hole, preventing the pre-assembly cylinder from detaching from the anchor hole.

[0013] As a further improvement to the above solution, a locking groove is provided at one end of the pre-assembled cylinder away from its opening, and the anchor rod has a locking block that engages with the locking groove.

[0014] As a further improvement to the above solution, the outer side of the lock block is provided with external threads, and the inner side of the lock groove is provided with internal threads that are compatible with the external threads.

[0015] As a further improvement to the above solution, the positioning device also includes a sealing mechanism, which is disposed on the side of the pre-assembly cylinder near the opening, and is used to simultaneously seal the gap between the inner wall of the anchor hole at the opening and the outer wall of the pre-assembly cylinder when the first diagonal brace rotates out of the tilt.

[0016] As a further improvement to the above solution, the sealing mechanism includes a ring body sleeved and fixed to the outside of the opening end of the pre-assembly cylinder and a pressure regulating component. An annular groove is formed on the outer periphery of the ring body. The opening of the annular groove is covered with an elastic layer that can completely seal the opening. Hydraulic oil is contained in the annular groove. The pressure regulating component is disposed on the pre-assembly cylinder and driven by the roller. When the anchor rod is inserted into the pre-assembly cylinder, it can pressurize the hydraulic oil to cause the elastic layer to expand and deform so as to squeeze and seal against the inner wall of the anchor hole.

[0017] As a further improvement to the above solution, the elastic layer is a rubber ring, and the inner side of the rubber ring is sealed with the wall of the settling tank to form a liquid phase space that allows the hydraulic oil to flow.

[0018] As a further improvement to the above solution, the pressure regulating component includes a first bevel tooth, which is coaxially fixed to the axle of the roller. A limit groove is fixed on the pre-assembly cylinder, and a limit block is slidably engaged in the limit groove. A screw is fixed to one end of the limit block, and a transmission cylinder parallel to the axial direction of the pre-assembly cylinder is threaded onto one end of the screw. The transmission cylinder is rotatably mounted on the outer wall of the pre-assembly cylinder via a bracket. A second bevel tooth that mates with the first bevel tooth is fixed to one end of the transmission cylinder, and a connecting rod is fixed to the other end of the limit block. The ring body has a plug groove with one end connected to the sinker, and a piston that mates with the plug groove is provided inside the other end of the plug groove. One side of the piston is fixedly connected to one end of the connecting rod, and hydraulic oil is contained in the plug groove.

[0019] As a further improvement to the above solution, the end of the anchor bolt located outside the anchor hole has a screw head.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. The debris flow interception system of the present invention, which is easy to install and use, can easily complete the installation and positioning of the anchor rod in the large-diameter anchor hole by adding a positioning device in the anchor rod and the large-diameter anchor hole. It is firm and stable, ensuring installation efficiency and construction period. At the same time, the monitoring equipment can monitor the environmental information at the interception dam in real time when a debris flow occurs, so as to understand the interception status of each interception dam on the debris flow.

[0022] 2. The debris flow blocking system of the present invention, which is easy to install and use, can achieve the following by means of a diagonal bracing mechanism in the positioning device: when the anchor rod is inserted into the pre-installed cylinder, the outer wall of the anchor rod will contact the roller and drive the roller to rotate. The end of the first diagonal bracing rod away from the roller will tilt after rotating with the roller and extend out of the outer side of the pre-installed cylinder to press and fit with the inner wall of the anchor hole, so as to prevent the pre-installed cylinder from detaching from the anchor hole. This can make the anchor hole, anchor rod and pre-installed cylinder form a strong and connected whole, ensuring the installation stability of the anchor rod in the large-diameter anchor hole.

[0023] 3. The debris flow barrier system of the present invention, which is easy to install and use, can work simultaneously with the diagonal bracing mechanism when the anchor rod is inserted into the pre-installed cylinder through the sealing mechanism in the positioning device. It can completely seal the outer side of the pre-installed cylinder and the inner side of the anchor hole at the opening position of the pre-installed cylinder. This not only prevents the environmental erosion of the various structural components of the positioning device in the anchor hole after the anchor rod is inserted, but also allows the elastic layer that expands and deforms to a certain extent to abut and squeeze against the inner wall of the anchor hole, playing a role in positioning and fixing. This further prevents the pre-installed cylinder from detaching from the anchor hole, making the installation of the barrier dam in the gully more stable.

[0024] 4. The debris flow blocking system of the present invention, which is easy to install and use, can work simultaneously with the diagonal bracing mechanism and sealing mechanism in the positioning device when the anchor is inserted into the pre-installed cylinder, through the structure of the first sprocket, the second sprocket, and the second diagonal bracing rod. It can not only support the first diagonal bracing rod against the anchor hole, but also fix the position of the limiting block in the limiting groove, so as to ensure that the expansion and deformation state of the elastic layer can be effectively maintained, making the connection between the anchor and the pre-installed cylinder in the anchor hole more stable.

[0033] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0034] Example 1

[0035] Please combine Figures 1 to 6 The debris flow containment system is easy to install and use, including at least one retaining dam 2 set sequentially in the valley 1 along the flow direction and monitoring equipment 3 set at the corresponding position of each retaining dam 2. The monitoring equipment is used to monitor the environmental information at the retaining dam 2 in real time.

[0036] The monitoring equipment in this embodiment can be a camera installed at the retaining dam 2 and its back-end information processing equipment. The monitoring equipment can facilitate real-time observation of the blocking effect of each retaining dam 2 on the debris flow in the valley when a debris flow occurs.

[0037] Anchor holes 4, corresponding to the positions of retaining dam 2, are pre-drilled in the gully 1. Anchor rods 6, which can be inserted into the anchor holes 4, are installed on the retaining dam 2. A positioning device is installed in the anchor holes 4. When the diameter of the anchor hole 4 is larger than the outer diameter of the anchor rod 6, the positioning device is used to lock and fix the anchor rod 6 in the corresponding anchor hole 4, so that the anchor rod 6 can be stably and reliably riveted and positioned in the anchor hole 4 with a diameter larger than its rod diameter, thereby improving the adaptability of the anchor rod 6 to the larger diameter anchor hole 4 and the stability of the retaining dam 2 installed in the gully 1.

[0038] The positioning device includes a pre-installed cylinder 5, one end of which is closed and can be inserted into the anchor hole 4, and the other end has an opening (not shown) for the anchor rod 6 to be inserted. The pre-installed cylinder 5 is provided with a diagonal bracing mechanism. When the anchor rod 6 is inserted into the pre-installed cylinder 5, the diagonal bracing mechanism is used to lock and fix the anchor hole 4 and the pre-installed cylinder 5 to prevent the pre-installed cylinder 5 from dislodging from the anchor hole 4.

[0039] The diagonal bracing mechanism includes two rollers 7 that are axially opposite to each other and rotatably mounted on the outer wall of the pre-assembly cylinder 5. Part of the roller 7 extends into the pre-assembly cylinder 5 to contact the outer wall of the anchor rod 6 inserted into the pre-assembly cylinder 5. A first diagonal bracing rod 8 is fixed to the outer periphery of the roller 7.

[0040] In this embodiment, when the anchor rod 6 is inserted into the pre-installed cylinder 5, the outer wall of the anchor rod 6 will contact the roller 7 and drive the roller 7 to rotate. The end of the first diagonal brace 8 away from the roller 7 will tilt after rotating with the roller 7 and extend out of the outer side of the pre-installed cylinder 5 to press and fit with the inner wall of the anchor hole 4, so as to prevent the pre-installed cylinder 5 from detaching from the anchor hole 4.

[0041] A locking groove 21 is provided at one end of the pre-installed cylinder 5 away from its opening. The anchor rod 6 has a locking block 22 that locks into the locking groove 21. This allows the anchor rod 6 to form a firmly connected whole with the pre-installed cylinder 5 after it is inserted into the pre-installed cylinder 5. It also helps to maintain the stability of the first diagonal brace 8 in its tilted state, thereby forming a stable abutting fixed structure between the pre-installed cylinder 5 and the anchor hole 4.

[0042] Specifically, in this embodiment, the outer side of the locking block 22 is provided with external threads, and the inner side of the locking groove 21 is provided with internal threads that are compatible with the external threads, so as to facilitate the assembly and disassembly of the locking block 22 and the locking groove 21.

[0043] The positioning device also includes a sealing mechanism, which is located on the side of the pre-installed cylinder 5 near the opening. When the first diagonal brace 8 rotates out of the tilt, it simultaneously seals the gap between the inner wall of the anchor hole 4 at the opening and the outer wall of the pre-installed cylinder 5, so as to prevent the environment from corroding the various structural components of the positioning device in the anchor hole 4 after the anchor rod 6 is inserted.

[0044] The sealing mechanism includes a ring 16 sleeved and fixed to the outside of the opening end of the pre-installed cylinder 5 and a pressure regulating component. The outer periphery of the ring 16 has an annular groove 19, the opening of which is covered by an elastic layer 20 capable of completely sealing. Hydraulic oil is contained within the annular groove 19. The pressure regulating component, mounted on the pre-installed cylinder 5 and driven by rollers 7, pressurizes the hydraulic oil when the anchor rod is inserted into the pre-installed cylinder 5, causing the elastic layer 20 to expand and deform, thus sealing against the inner wall of the anchor hole 4. This not only prevents environmental corrosion of the positioning device components within the anchor hole 4 after the anchor rod 6 is inserted, but also allows the expanded elastic layer 20 to a certain extent to abut and press against the inner wall of the anchor hole 4, providing a positioning and fixing function. This further prevents the pre-installed cylinder from detaching from the anchor hole 4, making the installation of the retaining dam 2 in the valley 1 more stable.

[0045] In this embodiment, the elastic layer 20 can be a rubber ring, and the inner side of the rubber ring and the wall of the settling tank 19 are sealed to form a liquid phase space that allows hydraulic oil to flow.

[0046] The pressure regulating assembly includes a first bevel tooth 9, which is coaxially fixed on the axle of the roller 7. A limit groove 13 is fixed on the pre-assembly cylinder 5. A limit block 14 is slidably engaged in the limit groove 13. A screw 12 is fixed to one end of the limit block 14. A transmission cylinder 11 parallel to the axial direction of the pre-assembly cylinder 5 is threaded onto one end of the screw 12. The transmission cylinder 11 is rotatably mounted on the outer wall of the pre-assembly cylinder 5 via a bracket. A second bevel tooth 10 that cooperates with the first bevel tooth 9 is fixed to one end of the transmission cylinder 11. A connecting rod 15 is fixed to the other end of the limit block 14. The ring body 16 has a plug groove 17 with one end connected to the sinker 19. A piston 18 that cooperates with the plug groove 17 is provided inside the other end of the plug groove 17. One side of the piston 18 is fixedly connected to one end of the connecting rod 15. Hydraulic oil is contained in the plug groove 17.

[0047] In this embodiment, when the anchor rod 6 is inserted into the pre-installed cylinder 5, it will not only cause the first diagonal brace 8 to rotate and tilt and press against the inner wall of the anchor hole 4, preventing the pre-installed cylinder 5 from leaving the anchor hole, but the roller 7 will also drive the first bevel tooth 9, the second bevel tooth 10, and the transmission cylinder 11 to rotate, so that the transmission cylinder 11 and the screw 12 have mutual thread action, and under the action of the limiting groove 13, the limiting block 14 will move. The limiting block 14 drives the piston 18 to squeeze the hydraulic oil in the plug groove 17 through the connecting rod 15, changing the hydraulic pressure in the liquid phase space, so that the elastic layer 20 expands and deforms to press and seal against the inner wall of the anchor hole 4.

[0048] The anchor bolt 6 has a screw head at one end located outside the anchor hole 4 to facilitate the installation and removal of the anchor bolt 6 during manual operations.

[0049] Example 2

[0050] The difference between this embodiment and embodiment 1 is that in this embodiment, a first sprocket 23 is coaxially fixed on the roller 7, a second sprocket 24 is elastically inserted on the first diagonal support rod 8, the first sprocket 23 and the second sprocket 24 are connected by chain drive, a second diagonal support rod 25 is fixed on the outer periphery of the second sprocket 24, and a rod slot 26 is provided on the limiting block 14 to engage with the free end of the second diagonal support rod 25.

[0051] A spool (not shown) is fixedly inserted into the center of the second sprocket 24. A rotating hole (not shown) is opened on the first diagonal brace 8. One end of the spool is inserted into the rotating hole, and a coil spring (not shown) is sleeved on the outer side of the end of the spool inserted into the rotating hole. One end of the coil spring is fixed to the inner side wall of the rotating hole, and the other end is fixed to the outer side wall of the spool.

[0052] When the anchor rod 6 is not inserted into the pre-installed cylinder 5, the first diagonal brace 8 and the second diagonal brace 25 are both parallel to the axis of the pre-installed cylinder 5. When the anchor rod 6 is inserted into the pre-installed cylinder 5, the first diagonal brace 8 rotates outward and tilts, and the second diagonal brace 25 moves synchronously with the first diagonal brace 8. At the same time, the roller 7 drives the first sprocket 23, and the first sprocket 23 drives the second sprocket 24 to rotate through the chain (the coil spring deforms), so that the free end of the second diagonal brace 25 rotates towards the limiting block 14 under the drive of the second sprocket 24, and gradually engages into the rod slot 26 on the limiting block 14. This allows the second diagonal brace 25 to not only support the first diagonal brace 8 against the anchor hole 4, but also to fix the position of the limiting block 14 in the limiting groove 13, so as to ensure that the expansion deformation state of the elastic layer 20 can be effectively maintained.

[0053] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
