Description

Technical Field

[0001] The invention relates to the technical field of flood discharge tunnel protection engineering, and in particular to a protection reinforcement structure of a reservoir flood discharge tunnel. Background Art

[0002] During the design and operation of a reservoir spillway, there may be a variety of problems that affect not only the function of the spillway, but also the overall safety of the reservoir. Due to long-term exposure to the natural environment, the concrete or metal structure of the spillway may age, corrode or wear, resulting in a decrease in strength. High-speed water flow will scour the bottom and sides of the spillway, which may cause structural damage or unstable foundations. The silt and particles in the water flow may erode the surface material of the spillway, causing surface wear or shedding.

[0003] In order to ensure the safety and effective operation of the reservoir spillway, it is necessary to strictly control the quality of each link in the design, construction, maintenance and management, and promptly discover and solve problems. Through regular inspection, maintenance and necessary reinforcement measures, the service life of the spillway can be effectively extended and the safe operation of the reservoir can be guaranteed.

[0004] For example, Chinese patent publication number CN114320402B discloses a dangerous rock protection device at the top of a flood discharge tunnel; It discloses a dangerous rock protection device at the top of a flood discharge tunnel, comprising a hydraulic support device and a first support arch arranged on the left and right sides of the inside of the tunnel, a second support arch arranged on the top of the first support arch; a plurality of support anchor rods are passed through the arc line on the first support arch and the second support arch; an elastic buffer device is arranged on the support anchor rod, the elastic buffer device comprises a first buffer arc plate fitted with the first support arch, a second buffer arc plate fitted with the second support arch, and an elastic member arranged between the first buffer arc plate and the second buffer arc plate, the first buffer arc plate and the second buffer arc plate are both slidably connected to the outer side of the support anchor rod; a plurality of buffer capsules are also arranged between the first support arch and the second support arch, and the inside of the buffer capsules is filled with non-Newtonian liquid; the present invention can effectively support the rock mass at the top of the tunnel, and support and buffer the rock mass when the rock mass is loose or collapsed, so as to effectively ensure the safety of the tunnel.

[0005] However, the above device still has some shortcomings in actual use: 1. The above-mentioned device effectively supports the rock mass at the top of the tunnel through the guard anchor rods, and supports and cushions the rock mass when the rock mass loosens or collapses, effectively ensuring the safety of the tunnel. However, the simple insertion of the guard anchor rods may cause secondary damage to the tunnel, and there is a lack of devices to reinforce the top of the tunnel during the support process.

[0006] 2. When maintenance is required, the device needs to be removed, and the Hongdong body cannot be supported. The rock mass on the top of the cave will lose the necessary support, which may lead to a series of safety hazards. Especially when personnel enter the cave for maintenance work, the risk is particularly prominent and may cause personal injury.

[0007] Therefore, based on the above-stated viewpoints, it is of great significance to improve and perfect the dangerous rock protection device on the top of the flood discharge tunnel. It can add devices to reinforce the top of the tunnel during the support process, and can further support the rock mass on the top of the tunnel, reducing the risk of maintenance operations.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-Figure 8 Embodiments of the present invention are described in detail.

[0031] The embodiment of the present application discloses a protective reinforcement structure for a reservoir spillway tunnel. The present invention is mainly used in the process of protecting the spillway tunnel. In terms of technical effect, it can avoid the problem that the supporting effect is poor and secondary damage may be caused to the wall by simply inserting the support rod into the wall of the spillway tunnel; further, the present invention can also solve the problem of automatically repairing the top of the spillway tunnel when the spillway tunnel needs to be repaired, and can also provide support during the repair process to ensure safety during the repair process. Example

[0032] Reference Figure 1 , Figure 2 and Figure 4As shown, it includes a support shaft 1, support rings 10 are installed at both ends of the support shaft 1, support devices 2 are arranged on the opposite sides of the two support rings 10, mounting seats 11 are arranged at both ends of the support shaft 1, and walking wheels 12 are slidably arranged on the mounting seats 11.

[0033] It should be noted that the rotation direction of the running wheel 12 is consistent with the extension direction of the support shaft 1, and the running wheel 12 moves the support shaft 1 along the direction of the protection hole.

[0034] A repair device 3 is also provided on the support shaft 1. The repair device 3 enters the spillway tunnel through the running wheels 12. The cracks generated inside the spillway tunnel are repaired by the repair device 3, and the spillway tunnel is reinforced to ensure the operation of the spillway tunnel.

[0035] The repair device 3 includes a movable rod 30, and the two supporting rings 10 are each provided with an arc-shaped sliding groove 31, and a connecting block 32 is slidably arranged in the sliding groove 31. The two connecting blocks 32 are jointly provided with the movable rod 30, and the two connecting blocks 32 slide in the sliding groove 31. When the repair device 3 enters the interior of the spillway tunnel, the rotation angle of the movable rod 30 is adjusted according to the top of the spillway tunnel with an arc-shaped top to adapt to the upper end of the spillway tunnel. A penetrating driving groove is provided on the movable rod 30, and a reciprocating screw 33 is rotatably installed in the driving groove, and a threaded seat 34 is threadedly installed on the reciprocating screw 33. A penetrating fixed shaft 35 is arranged on the threaded seat 34, and a repair unit 36 ​​is arranged inside the fixed shaft 35. The reciprocating screw 33 moves the repair unit 36 ​​on the threaded seat 34 along the length direction of the movable rod 30, and the position of the movable rod 30 and the position of the repair unit 36 ​​on the movable rod 30 can be adjusted. The top of the spillway tunnel between the two supporting rings 10 can be repaired and reinforced.

[0036] Reference Figure 2 and Figure 3 As shown, it is a schematic diagram of the structure for supporting the top of the flood discharge tunnel; specifically, the supporting device 2 includes a fixed plate 20, which is sleeved on the supporting shaft 1 on the opposite side of the supporting ring 10, and a driving plate 21 is also rotatably arranged on the opposite side of the two fixed plates 20. A plurality of support rods 22 are equidistantly slidably arranged on the fixed plate 20 along its axis, and a plurality of arc-shaped guide grooves 23 are opened on the driving plate 21 along its axis. A matching shaft 24 is installed on one end of the support rod 22 close to the supporting shaft 1, and the matching shaft 24 is slidably arranged in the guide groove 23.

[0037] When it is necessary to drive the support rod 22 to slide on the fixed plate 20 to adapt to the top of the flood discharge tunnel, the driving plate 21 is rotated, and the guide groove 23 on the driving plate 21 will drive the matching shaft 24 to slide in the reverse direction. At this time, the matching shaft 24 will slide on the fixed plate 20 with the support rod 22.

[0038] It should be noted that the support rod 22 of the present invention slides radially along the fixed plate 20, and it cannot rotate circumferentially around the support shaft 1. The support rod 22 is controlled by the guide groove 23 on the drive plate 21, that is, by driving the drive plate 21 to rotate, and then the support rod 22 is moved radially along the fixed plate 20 with the cooperation of the matching shaft 24 and the guide groove 23. This means that when the drive plate 21 does not rotate, the support rod 22 will remain stationary, that is, it will not slide radially along the fixed plate 20.

[0039] Reference Figure 2 and Figure 3 As shown, it is a schematic diagram of the structure that causes the driving plate 21 to rotate; specifically, a driving member 5 that rotates the driving plate 21 is provided on the support rod 22, and the driving member 5 includes a first gear 50, and the two first gears 50 are rotatably arranged on the side surface opposite to the fixed plate 20, and a first gear ring 51 is provided on the outer side of the driving plate 21, and the first gear 50 is meshed with the first gear ring 51.

[0040] The first gear 50 rotates with the first gear ring 51 , and the first gear ring 51 rotates with the driving plate 21 . The first gear 50 controls the rotation angle of the driving plate 21 , thereby controlling the sliding distance of the support rod 22 .

[0041] An arc plate is installed between the two supporting rings 10, and a first motor is installed on the arc plate. The first motor is a dual-axis motor. The two output shafts of the first motor are respectively connected to the first gears 50 on the two fixed plates 20. The support rods 22 at both ends of the support shaft 1 are controlled by the first motor to slide synchronously.

[0042] The sliding walking wheel 12 can control the height of the support shaft 1. When the spillway is arc-shaped on the top and straight on both sides, it can support the spillway. The supporting device 2 can also support a circular spillway. It can adapt to a variety of construction environments and be adjusted according to specific circumstances to ensure the effectiveness and stability of the support.

[0043] An arc-shaped abutment plate 40 is hingedly provided at one end of the support rod 22 away from the support shaft 1 , and a matching ball 41 is evenly rotatably mounted on the abutment plate 40 .

[0044] The rotation direction of the matching ball 41 is consistent with that of the running wheel 12. When the running wheel 12 moves with the supporting ring 10, the matching ball 41 will roll on the inner wall of the flood discharge tunnel to facilitate entry.

[0045] Reference Figure 4 and Figure 7As shown, it is a schematic diagram of the structure for reinforcing the spillway tunnel; specifically, the repair unit 36 ​​includes a repair shaft 360, a working groove 361 is opened inside the fixed shaft 35, the repair shaft 360 is rotatably and slidably set in the working groove 361, a matching block 362 is set at the bottom of the repair shaft 360, a spiral groove 363 is opened on the inner wall of the working groove 361, and the matching block 362 is slidably set in the spiral groove 363.

[0046] As the repair shaft 360 slides in the fixed shaft 35, the matching block 362 on the repair shaft 360 will slide inside the spiral groove 363, and then the spiral groove 363 can drive the repair shaft 360 to rotate in the reverse direction during the movement. When the spillway tunnel is repaired and reinforced, the repair shaft 360 will rotate into the spillway tunnel.

[0047] By controlling the moving distance of the repair shaft 360, adjustments can be made for spillways with different diameters or heights.

[0048] Reference Figure 4 and Figure 7 As shown, it is a schematic diagram of the structure that drives the repair shaft 360 to move; specifically, a driving ring 60 is sleeved on the bottom of the repair shaft 360, a sleeve rod 61 is rotatably installed on the support shaft 1, a support block 62 is slidably provided on the sleeve rod 61, and an electric push rod 63 is connected to the support block 62. The telescopic end of the electric push rod 63 passes through the fixed shaft 35 and is connected to the driving ring 60. The driving ring 60 is pushed by the electric push rod 63 to slide inside the fixed shaft 35, and the repair shaft 360 moves inside the fixed shaft 35.

[0049] A spring telescopic rod 64 is installed on the threaded seat 34 , and the telescopic end of the spring telescopic rod 64 is connected to the support block 62 .

[0050] When the threaded seat 34 moves with the fixed shaft 35 along the length direction of the reciprocating screw 33, the spring telescopic rod 64 will move the support block 62 and the threaded seat 34 synchronously, ensuring that the electric push rod 63 on the support block 62 and the fixed shaft 35 on the threaded seat 34 move synchronously, thereby ensuring the working efficiency of the repair shaft 360.

[0051] Reference Figure 4 and Figure 7 As shown, it is a structural schematic diagram of repairing the flood discharge tunnel; specifically, a baffle 70 is connected between the two supporting rings 10 below the supporting shaft 1, a storage box 71 is installed on the baffle 70, a self-priming pump 72 is installed above the storage box 71, the input end and the output end of the self-priming pump 72 are respectively connected to the storage box 71 and the inside of the repair shaft 360, and a plurality of discharge ports 73 are evenly opened on the repair shaft 360.

[0052] When the repair shaft 360 is inserted into the wall of the spillway tunnel, the self-priming pump 72 is started to transport the repair material in the storage box 71 to the inside of the repair shaft 360. The repair material will enter the cracks in the spillway tunnel through the discharge port 73 to repair the cracks, thereby achieving reinforcement and protection of the spillway tunnel.

[0053] Among them, the self-priming pump 72 is preferably an existing grouting pump that can suck and deliver cement repair slurry.

[0054] In addition, the repair materials include but are not limited to high-strength quick-drying cement-based repair mortar or chemical grouting materials. Different types of repair materials are selected according to the specific crack conditions to repair cracks and potholes on the wall of the flood discharge tunnel.

[0055] Reference Figure 4 , Figure 5 and Figure 6 As shown, that is, a schematic diagram of the structure for driving the matching block 362 to slide inside the working groove 361; specifically, a driving unit 8 for driving the connecting block 32 to slide inside the slide groove 31 is provided on the supporting ring 10, and the driving unit 8 includes a driving shaft, and the driving shaft is rotatably arranged on the connecting block 32 passing through the supporting ring 10, and a second gear 81 is installed on one end of the driving shaft located on the outside of the supporting ring 10, and an arc-shaped second rack 82 is provided on the supporting ring 10, and the second rack 82 is meshed with the second gear 81.

[0056] A second motor is also installed on the connecting block 32 through a bracket, and the output end of the second motor is connected to the second gear 81. The second motor drives the second gear 81 to rotate, so that the second gear 81 slides along the slide groove 31 under the reverse action of the second rack 82, and then controls the movable rod 30 on the connecting block 32 to rotate along the axis of the fixed plate 20 to adapt to the upper surface of the flood discharge tunnel. Example

[0057] On the basis of the first embodiment, in order to further improve the repair effect of the repair device 3, a connecting rod 9 is also proposed, which is conducive to enhancing the synchronization of the movable rod 30 and the electric push rod 63, and ensuring that the electric push rod 63 moves synchronously with the fixed shaft 35 on the drive plate 21.

[0058] Reference Figure 8 As shown, it is a structural schematic diagram of the synchronous operation of the movable rod 30 and the electric push rod 63; specifically, the connecting rod 9 is arranged at both ends of the sleeve rod 61, and the end of the connecting rod 9 away from the sleeve rod 61 is connected to the second motor. When the connecting block 32 slides inside the slide groove 31, it will move synchronously with the second motor. At this time, the second motor will drive the sleeve rod 61 to rotate along the support shaft 1 as the center through the connecting rod 9, ensuring that when the fixed shaft 35 on the movable rod 30 moves with the movable rod 30, the electric push rod 63 can rotate synchronously without affecting the electric push rod 63 pushing the drive ring 60.

[0059] During operation: the first step is to move the support shaft 1 along the direction of the protection hole through the walking wheel 12. During the movement of the supporting ring with the walking wheel 12, the matching ball 41 will roll on the inner wall of the flood discharge hole, making it easy to enter.

[0060] Step 2: When driving to a fixed position, the first motor starts, and the first motor controls the first gear 50 at both ends of the support shaft 1 to rotate. The first gear 50 rotates with the first gear ring 51, and the first gear ring 51 rotates with the driving plate 21. The first gear 50 controls the rotation angle of the driving plate 21, and the guide groove 23 drives the matching shaft 24 to slide in the reverse direction, thereby controlling the sliding distance of the support rod 22 to adapt to the top shape of the flood discharge tunnel.

[0061] Step 3: The second motor drives the second gear 81 to rotate, so that the second gear 81 slides along the working groove 361 under the reverse action of the second rack 82, and then controls the driving plate 21 on the matching block 362 to rotate along the axis of the fixed plate 20.

[0062] Step 4: After the angle adjustment is completed, the reciprocating screw 33 moves the repair unit 36 ​​on the threaded seat 34 along the length direction of the movable rod 30 to adjust the position of the repair unit 36 ​​on the threaded seat 34 .

[0063] Step 5: After the adjustment is completed, the electric push rod 63 pushes the drive ring 60 to slide inside the fixed shaft 35, and moves the repair shaft 360 inside the fixed shaft 35. At this time, the matching block 362 on the repair shaft 360 will slide inside the spiral groove 363, and then the spiral groove 363 can drive the repair shaft 360 to rotate in the reverse direction during the movement. When the spillway tunnel is repaired and reinforced, the repair shaft 360 will rotate into the wall of the spillway tunnel.

[0064] Step 6: After entering the wall of the spillway tunnel, start the self-priming pump 72 to transport the repair material in the storage box 71 to the inside of the repair shaft 360. The repair material will enter the cracks of the spillway tunnel through the discharge port 73 to repair the cracks, thereby achieving reinforcement and protection of the spillway tunnel.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.

[0066] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
