Description

Technical Field

[0001] This utility model relates to the field of reservoir support technology, specifically a grid-type anchor-pull reinforcement structure for reservoir dam slope construction. Background Technology

[0002] In the construction and operation of water conservancy projects, reservoir dams, as core flood control and water storage facilities, have slope stability that is directly related to project safety and the safety of life and property in the surrounding areas. With the rapid development of my country's water conservancy industry, the service life of existing dams is increasing, the demand for new dams in areas with complex geological conditions is increasing, and the risk of slope instability caused by extreme weather is intensifying. Upgrading and optimizing dam slope reinforcement technology has become one of the core issues of concern in the industry.

[0003] However, in the use of existing technologies, lattice-type anchored structures are a commonly used reinforcement method. However, traditional anchor rods are mostly single rods that are fixed by friction after being inserted into the anchor hole. They have weak pull-out resistance and are easily pulled out by embankment slippage or external forces, leading to the failure of the lattice beam fixation. This makes it difficult to meet the long-term stable protection requirements. Therefore, a lattice-type anchored reinforcement structure for reservoir dam slope construction is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a grid-type anchored reinforcement structure for the construction of reservoir dam slopes, in order to solve the problem mentioned in the background art that the grid-type anchored structure is a commonly used reinforcement form, but traditional anchor rods are mostly single rods that are fixed by friction after being inserted into the anchor hole. They have weak pull-out resistance and are easily pulled out by embankment slippage or external forces, leading to the failure of grid beam fixation and making it difficult to meet the long-term stable protection requirements.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grid-type anchored reinforcement structure for reservoir dam slope construction, comprising a grid beam, a plurality of fixing blocks fixedly connected to the lower surface of the grid beam, a rotating block rotatably connected inside each fixing block, a connecting rod fixedly connected to the bottom end of the rotating block, a limiting block fixedly connected to the end of the connecting rod away from the rotating block, an anchor rod sleeved on the outer surface of the limiting block, a first spring sleeved on the outer surface of the connecting rod, the two ends of the first spring being fixedly connected to the upper surface of the limiting block and the inner top wall of the anchor rod respectively, a limiting groove being formed at the bottom end of the anchor rod, and a fixing device being provided at the bottom end of the anchor rod.

[0006] Preferably, the fixing device includes a support block, the outer surface of which is rotatably connected to the inner wall of the limiting groove.

[0007] Preferably, the anchor rod has a groove inside, and a fixing plate is slidably connected inside the groove.

[0008] Preferably, a second spring is fixedly connected to the top of the fixed plate, and the end of the second spring away from the fixed plate is fixedly connected to the inner wall of the slide groove.

[0009] Preferably, two sliders are fixedly connected to the lower surface of the fixing plate, and the bottom end of the slider is in contact with the surface of the support block.

[0010] Preferably, a baffle is fixedly connected to the front of the lattice beam, a water guide plate is fixedly connected to the back of the lattice beam, and a drain pipe is fixedly connected between the baffle and the water guide plate.

[0011] Preferably, a protrusion is fixedly connected to the left side of the water guide plate, and a groove is provided on the right side of the water guide plate, with the shape of the protrusion matching the shape of the groove.

[0012] Preferably, a locking block is fixedly connected to the left side of the lattice beam, and a locking groove is opened on the right side of the lattice beam, wherein the shape of the locking block is adapted to the shape of the locking groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are: The lattice-type anchored reinforcement structure for the reservoir dam slope construction utilizes a limiting groove at the bottom of the anchor rod, with a rotatable support block inside. When the anchor rod is inserted into the anchor hole, the support block is compressed and contracts. After full insertion, a second spring pushes a fixing plate, causing a slider to compress the support block, giving it a tendency to rotate out. When the anchor rod is subjected to a pull-out force, the support block unfolds and inserts into the inner wall of the anchor hole under the scraping of the soil, effectively preventing the anchor rod from being pulled out. This significantly improves the anchor rod's tensile strength and enhances the stability of the lattice beam. Simultaneously, when the lattice beam is subjected to impact or embankment slippage, generating tensile force, the lattice beam drives the connecting rod and the limiting block. The limiting block compresses the first spring, which provides shock absorption and buffering, preventing damage to the lattice beam due to severe stress and extending the structural service life.

[0016] Please see Figure 1-5 This utility model provides a technical solution: a grid-type anchored reinforcement structure for reservoir dam slope construction, including a grid beam 1. Multiple fixing blocks 12 are fixedly connected to the lower surface of the grid beam 1. Each fixing block 12 has a rotating block 19 rotatably connected inside. The fixing blocks 12 limit the position of the rotating block 19. A connecting rod 13 is fixedly connected to the bottom end of the rotating block 19. A limiting block 15 is fixedly connected to the end of the connecting rod 13 away from the rotating block 19. An anchor rod 8 is sleeved on the outer surface of the limiting block 15. The anchor rod 8 limits the position of the limiting block 15 and the connecting rod 13, allowing the limiting block 15 and the connecting rod 13 to slide inside the anchor rod 8.

[0017] A first spring 14 is fitted on the outer surface of the connecting rod 13. The two ends of the first spring 14 are fixedly connected to the upper surface of the limiting block 15 and the inner top wall of the anchor rod 8, respectively. The first spring 14 plays a role in damping the shock when the connecting rod 13 and the rotating block 19 are subjected to tension, and damping the impact force on the lattice beam 1 to prevent the lattice beam 1 from being damaged by violent impact. A limiting groove 9 is opened at the bottom end of the anchor rod 8, and a fixing device is provided at the bottom end of the anchor rod 8.

[0018] The fixing device includes a support block 10, the outer surface of which is rotatably connected to the inner wall of the limiting groove 9. The limiting groove 9 serves to limit the position of the support block 10. The anchor rod 8 has a sliding groove 16 inside, and a fixing plate 18 is slidably connected inside the sliding groove 16. The sliding groove 16 serves to limit the position of the fixing plate 18.

[0019] The top of the fixed plate 18 is fixedly connected to a second spring 17. The end of the second spring 17 away from the fixed plate 18 is fixedly connected to the inner wall of the slide groove 16. The fixed plate 18 is pushed by the second spring 17, causing the fixed plate 18 to drive the slider 11 to move downward under the limiting action of the slide groove 16.

[0020] Two sliders 11 are fixedly connected to the lower surface of the fixing plate 18. The bottom end of the slider 11 contacts the surface of the support block 10. Through the slider 11, the support block 10 is pushed to unfold inside the limiting groove 9, thereby improving the pull-out resistance of the anchor rod 8.

[0021] Among them, the front of the lattice beam 1 is fixedly connected to the baffle 2, and the back of the lattice beam 1 is fixedly connected to the water guide plate 3. The baffle 2 and the water guide plate 3 are fixedly connected to the drainage pipe 20. The baffle 2 plays a role in resisting the possible impact of floods, and the water guide plate 3 and the drainage pipe 20 guide the water flow on the bank, so that the water flow enters the reservoir through the drainage pipe 20, thus preventing the water flow from eroding the embankment and causing damage to the embankment.

[0022] The water guide plate 3 has a protrusion 4 fixedly connected to its left side and a groove 5 opened on its right side. The shape of the protrusion 4 matches the shape of the groove 5. Through the cooperation between the protrusion 4 and the groove 5, the water flows inside the water guide plate 3.

[0023] The left side of the lattice beam 1 is fixedly connected with a locking block 7, and the right side of the lattice beam 1 is provided with a locking groove 6. The shape of the locking block 7 is adapted to the shape of the locking groove 6. Through the limiting effect between the locking block 7 and the locking groove 6, it can facilitate the rapid splicing of multiple lattice beams 1.

[0024] Working principle: In use, the construction personnel first drill multiple anchor holes at the location where the lattice beam 1 is to be placed, matching the positions of the anchor rods 8. Then, the anchor rods 8 are inserted into the anchor holes one by one. At this time, the support block 10 is squeezed back into the limiting groove 9 by the anchor hole until the anchor rod 8 is fully inserted into the anchor hole. Then, under the pushing action of the second spring 17, the fixing plate 18 drives the slider 11 to slide inside the sliding groove 16 under the limiting action of the sliding groove 16, so that the slider 11 squeezes the support block 10, making the support block 10 tend to rotate out of the limiting groove 9. Then, the fixing block 12 and the rotating block 19 at the bottom of the lattice beam 1 are connected by bolts. Then, the locking block 7 of another lattice beam 1 is inserted into the locking groove 6, so that the two lattice beams 1 are spliced. At this time, the protrusion 4 and the groove 5 are also spliced. By fixing the position of the lattice beam 1, the lattice beam 1 is aligned with the embankment. To protect the lattice beam 1, baffle 2 is used to block potential floods, preventing the strong force of the floodwaters from carrying mud and damaging the embankment. At the same time, water guide plate 3 and drainage pipe 20 are used to guide the water on the embankment, preventing the water from scouring the embankment as it flows into the river channel. When the lattice beam 1 is pulled out by the slippage of the embankment, causing the anchor rod 8 to move out of the anchor hole, the support block 10, which was originally inclined to open, is scraped by the mud on the inner wall of the anchor hole, causing the support block 10 to insert into the inner wall of the anchor hole, thus opening the support block 10 and preventing the anchor rod 8 from being pulled out. This makes the position of the lattice beam 1 more stable and improves the service life of the lattice beam 1. At the same time, when the lattice beam 1 is subjected to a violent impact, the lattice beam 1 can drive the rotating block 19 and the connecting rod 13 to slide inside the anchor rod 8, causing the limiting block 15 to compress the first spring 14. The first spring 14 reduces the impact force on the lattice beam 1 and reduces the probability of damage to the lattice beam 1.
