Description

Technical Field

[0001] This utility model relates to the field of tunnel reinforcement technology, specifically a tunnel reinforcement structure. Background Technology

[0002] Tunnel reinforcement is a key engineering measure in tunnel construction and operation and maintenance. It addresses issues such as unstable surrounding rock, structural cracks, and water seepage by using methods such as concrete grouting, support, and structural reinforcement to improve the tunnel's load-bearing capacity, impermeability, and stability, inhibit the expansion of defects, prevent the risk of collapse, ensure the long-term safe passage of the tunnel, and adapt to complex geological conditions and operational wear scenarios.

[0003] Tunnel surrounding rock is prone to cracks due to changes in geological conditions, leading to frequent water seepage problems. Traditional pumping methods rely heavily on manual operation, resulting in incomplete removal of accumulated water. Residual water can easily react with grouting materials, reducing the bonding strength and leaving potential for future water seepage. At the same time, the timing of reinforcement lacks precise judgment, requiring continuous manual monitoring of seepage and switching between procedures. This is not only inefficient but also prone to errors in judgment, leading to reinforcement before the water has been completely drained or delays in reinforcement after pumping, causing problems with the connection between procedures. Utility Model Content

[0004] The purpose of this invention is to provide a tunnel reinforcement structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tunnel reinforcement structure, including a steel plate support, a pumping component inside the steel plate support, and a reinforcement component inside the steel plate support;

[0006] The pumping assembly includes a pumping pipe, and a pumping pump is fixedly connected to one end of the outer surface of the pumping pipe. A water delivery pipe is fixedly connected inside the pumping pump, and a first water tank is fixedly connected to the end of the water delivery pipe away from the pumping pump. A float plate is provided inside the first water tank, and a first magnet is fixedly connected to one side of the outer surface of the float plate. A plug tube is fixedly connected to the outer surface of the first water tank, and a second magnet is slidably embedded inside the plug tube. A push rod is fixedly connected to one end of the outer surface of the second magnet, and a plug head is slidably embedded inside the plug tube.

[0007] The reinforcement assembly includes multiple air tubes, each with an air cylinder fixedly connected to its outer surface. Each air cylinder has an air rod fixedly connected to its interior, and each air rod has a sealing ring fixedly connected to its outer surface. Each air cylinder has an inner shell fixedly connected to its interior, and each air cylinder has a ventilation pipe fixedly connected to its interior. Each ventilation pipe has a support block fixedly connected to its outer surface, and each air rod has a fixing bolt fixedly connected to its output end.

[0008] Optionally, a spring is fixedly connected to one end of the outer surface of the plug, and the spring is fixedly connected inside the plug tube, and an air pump is fixedly connected to the end of the air tube away from the air cylinder.

[0009] Optionally, the steel plate bracket has multiple ventilation holes inside, and multiple support legs are fixedly connected inside the steel plate bracket.

[0010] Optionally, support plates are fixedly connected to both sides of the outer surface of the steel plate bracket, and multiple air cylinders are fixedly connected to one end of the outer surface of the support plates.

[0011] Optionally, the water pump is fixedly connected to one side of the outer surface of the steel plate support.

[0012] Optionally, the support block is internally connected to the steel plate bracket.

[0013] Optionally, a drain pipe is fixedly connected inside the first water tank, and a second water tank is fixedly connected to the end of the drain pipe away from the first water tank.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The steel plate bracket is fixed to the tunnel construction area via its bottom support legs, allowing the water pumping pipe to extend to the seepage gap in the tunnel. The water pump, fixed to one side of the steel plate bracket, is turned on. The pump draws in the seepage water through the water pumping pipe and then transports it to the first water tank via the water delivery pipe. At this time, the water level in the first water tank rises, and the floating plate rises synchronously, causing the first magnet fixed to the side of the floating plate to move away from the second magnet inside the plug pipe, preventing seepage water from flowing back into the gap. When the tunnel seepage water is pumped out and the water level in the first water tank gradually drops, the floating plate sinks synchronously with the water level until it falls below the height of the drain pipe. At this point, the first magnet and the second magnet inside the plug pipe approach each other, using the repulsive force of opposite magnetic poles to push the float away from the seepage gap. The second magnet slides, which in turn drives the push rod fixed to the second magnet to compress the plug, causing the plug to move inside the plug tube. After the water is drained, the spring drives the plug to reset, opening the air passage and realizing automatic triggering of reinforcement after the seepage is drained. This ensures that subsequent reinforcement is only initiated when there is no seepage interference in the gap, avoiding dilution of the grouting material by residual seepage. The magnetic trigger response is precise and suitable for intermittent seepage scenarios in tunnels. The combination of a water pump, a water pipe, a first water tank, and a second water tank can completely drain the seepage in the gap. The second water tank is larger than the first water tank to ensure that there is no residual water in the gap when reinforcement is triggered, providing a dry and clean construction environment for grouting and significantly improving the bonding strength between the cement grout and the surrounding rock and support.

[0016] 2. After the plug opens the air passage, the air pump connected to the air pipe is turned on. The air pump delivers airflow through the air pipe to the air cylinder fixed on the steel plate support plate. The airflow pushes the air rod out. Multiple sealing rings on the outer surface of the air rod fit tightly against the inner shell to ensure the airtightness of the air cylinder and prevent airflow leakage from affecting the support force. When the air rod extends, it lifts the support block. The support block at the end of the ventilation pipe fits against the tunnel rock surface or the grouted cement layer to achieve stable support. At the same time, some airflow is discharged from the support block through the ventilation pipe and blown directly into the cement layer to dry it. Combined with the ventilation holes on the surface of the steel plate support to assist in heat dissipation, it accelerates cement curing. Through the above technical solution, the air-driven support can be adapted to the stress requirements of different areas of the tunnel by adjusting the air pressure of the air pump. The sealing rings ensure the stability of the support force. The built-in ventilation pipe prevents the drying airflow from interfering with the grouting layer, realizing the integration of support and drying, improving the efficiency and stability of tunnel reinforcement. The ventilation and drying improve the stability of cement drying, solves the problem of the traditional surface drying with dry outside and wet inside, accelerates the cement curing efficiency, and shortens the construction cycle.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 6 This utility model provides a tunnel reinforcement structure, including a steel plate support 1, a water pumping component inside the steel plate support 1, and a reinforcement component inside the steel plate support 1.

[0027] The pumping assembly includes a pumping pipe 2, and a pumping pump 201 is fixedly connected to one end of the outer surface of the pumping pipe 2. A water delivery pipe 202 is fixedly connected inside the pumping pump 201, and a first water tank 203 is fixedly connected to one end of the water delivery pipe 202 away from the pumping pump 201. A float plate 204 is provided inside the first water tank 203, and a first magnet 205 is fixedly connected to one side of the outer surface of the float plate 204. A plug tube 211 is fixedly connected to the outer surface of the first water tank 203, and a second magnet 207 is slidably embedded inside the plug tube 211. A push rod 208 is fixedly connected to one end of the outer surface of the second magnet 207, and a plug head 210 is slidably embedded inside the plug tube 211.

[0028] The reinforcement assembly includes multiple air pipes 3, and air cylinders 301 are fixedly connected to the outer surfaces of the multiple air pipes 3. Air rods 302 are fixedly connected to the inside of the multiple air cylinders 301, and sealing rings 303 are fixedly connected to the outer surfaces of the multiple air rods 302. Inner shells 304 are fixedly connected to the inside of the multiple air cylinders 301. Ventilation pipes 305 are fixedly connected to the inside of the multiple air cylinders 301, and support blocks 307 are fixedly connected to the outer surfaces of the multiple ventilation pipes 305. Fixing bolts 306 are fixedly connected to the output ends of the multiple air rods 302.

[0029] Through the above technical solution, the steel plate bracket 1 is fixed to the tunnel construction area via the bottom support leg 103, allowing the water pumping pipe 2 to extend to the tunnel seepage gap. The water pump 201, fixed to one side of the steel plate bracket 1, is activated. The water pump 201 draws in seepage water through the water pumping pipe 2, and then transports the seepage water to the first water tank 203 via the water delivery pipe 202. At this time, the water level in the first water tank 203 rises, and the floating plate 204 floats upwards simultaneously, causing the first magnet 205 fixed to the side of the floating plate 204 to move away from the second magnet 207 inside the plug pipe 211, preventing seepage water from flowing back into the gap. When the tunnel seepage water is pumped out and the water level in the first water tank 203 gradually decreases, the floating plate 204 sinks synchronously with the water level until it drops below the height of the drain pipe 206. At this point, the first magnet 205 and the second magnet 207 inside the plug pipe 211 move closer to each other. The magnetic attraction force of opposite magnetic poles repulses and pushes the second magnet 207 to slide, which in turn drives the push rod 208 fixed to the second magnet 207 to compress the plug head 210, causing the plug head 210 to move inside the plug tube 211. After the water is drained, the spring 209 drives the plug head 210 to reset, opening the passage of the air tube 3, realizing automatic triggering of reinforcement after the seepage is drained. This ensures that subsequent reinforcement is only started when there is no seepage interference in the gap, avoiding the grouting material being diluted by residual seepage. The magnetic triggering response is accurate and suitable for intermittent seepage scenarios in tunnels. The combination of the water pump 201, the water pipe 2, the first water tank 203, and the second water tank 5 can completely drain the seepage in the gap. The second water tank 5 is larger than the first water tank 203, ensuring that there is no residual water in the gap when reinforcement is triggered, providing a dry and clean construction environment for grouting, and greatly improving the bonding strength between the cement grout and the surrounding rock and support.

[0030] Through the above technical solution, when the plug 210 opens the air pipe 3 passage, the air pump 4 connected to the air pipe 3 is turned on. The air pump 4 delivers airflow to the air cylinder 301 fixed on the support plate 102 of the steel plate bracket 1 through the air pipe 3. The airflow pushes the air rod 302 to extend. Multiple sealing rings 303 fitted on the outer surface of the air rod 302 are tightly fitted with the inner shell 304 to ensure the airtightness of the air cylinder 301 and prevent airflow leakage from affecting the supporting force. When the air rod 302 extends, it lifts the support block 307. The support block 307 at the end of the ventilation pipe 305 fits against the tunnel rock surface or the cement layer after grouting to achieve stable support. At the same time, some airflow passes through... Ventilation duct 305 extends from support block 307 and blows air directly into the cement layer for drying. It works in conjunction with ventilation holes 101 on the surface of steel plate bracket 1 to assist in heat dissipation and accelerate cement curing. Through the above technical solution, the air-driven support can adapt to the stress requirements of different areas of the tunnel by adjusting the air pressure of air pump 4. Sealing ring 303 ensures stable support force. The built-in ventilation duct 305 avoids the airflow from interfering with the grouting layer, realizing the integration of support and drying, improving the efficiency and stability of tunnel reinforcement. The ventilation and drying improve the stability of cement drying, solve the problem of traditional surface drying with dry outside and wet inside, accelerate cement curing efficiency, and shorten the construction cycle.

[0031] Specifically, a spring 209 is fixedly connected to one end of the outer surface of the plug 210, and the spring 209 is fixedly connected to the inside of the plug tube 211. An air pump 4 is fixedly connected to the end of the air tube 3 away from the air cylinder 301.

[0032] Through the above technical solution, the spring 209 resets the plug 210, and the air pump 4 supplies air to the air cylinder 301.

[0033] Specifically, the steel plate bracket 1 has multiple ventilation holes 101 inside, and multiple support legs 103 are fixedly connected inside the steel plate bracket 1.

[0034] The above technical solution allows the steel plate support 1 to be air-dried through the ventilation hole 101 and supported by the support leg 103.

[0035] Specifically, support plates 102 are fixedly connected to both sides of the outer surface of the steel plate bracket 1, and multiple air cylinders 301 are fixedly connected to one end of the outer surface of the support plate 102.

[0036] Through the above technical solution, the support plate 102 is fixed by the steel plate bracket 1, and the air cylinder 301 is fixed by the support plate 102.

[0037] Specifically, the water pump 201 is fixedly connected to one side of the outer surface of the steel plate bracket 1.

[0038] The above technical solution is used to fix the water pump 201 by means of the steel plate bracket 1.

[0039] Specifically, the support block 307 is internally connected to the steel plate bracket 1.

[0040] The above technical solution enables the air-drying steel plate bracket 1 through the air holes of the support block 307.

[0041] Specifically, a drain pipe 206 is fixedly connected inside the first water tank 203, and a second water tank 5 is fixedly connected to the end of the drain pipe 206 away from the first water tank 203.

[0042] The above technical solution allows water to be discharged to the second water tank 5 via the drain pipe 206.

[0043] In use, the steel plate bracket 1 is fixed to the tunnel construction area via the bottom support leg 103, allowing the water pumping pipe 2 to extend to the tunnel seepage gap. The water pump 201, fixed to one side of the steel plate bracket 1, is turned on. The water pump 201 draws in seepage water through the water pumping pipe 2, and then transports the seepage water to the first water tank 203 via the water delivery pipe 202. At this time, the water level in the first water tank 203 rises, and the float 204 floating in the water rises simultaneously, causing the first magnet 205 fixed to the side of the float 204 to move away from the second magnet 207 inside the plug pipe 211, preventing seepage water from flowing back into the gap. When the tunnel seepage water is pumped out and the water level in the first water tank 203 gradually decreases, the float 204 sinks synchronously with the water level until it drops below the height of the drain pipe 206. At this point, the first magnet 205 and the second magnet 207 inside the plug pipe 211 move closer together, utilizing... The opposing magnetic attraction forces push the second magnet 207 to slide, which in turn drives the push rod 208 fixed to the second magnet 207 to compress the plug head 210, causing the plug head 210 to move inside the plug tube 211. After the water is drained, the spring 209 drives the plug head 210 to reset, opening the passage of the air tube 3, realizing automatic triggering of reinforcement after the seepage is drained. This ensures that subsequent reinforcement is only started when there is no seepage interference in the gap, avoiding the grouting material being diluted by residual seepage. The magnetic trigger response is accurate and suitable for intermittent seepage scenarios in tunnels. The combination of the water pump 201, the water pipe 2, the first water tank 203, and the second water tank 5 can completely drain the seepage in the gap. The second water tank 5 is larger than the first water tank 203, ensuring that there is no residual water in the gap when reinforcement is triggered, providing a dry and clean construction environment for grouting, and greatly improving the bonding strength between cement grout and surrounding rock and support.

[0044] When the plug 210 opens the air passage 3, the air pump 4 connected to the air passage 3 is turned on. The air pump 4 delivers airflow through the air passage 3 into the air cylinder 301 fixed on the support plate 102 of the steel plate bracket 1. The airflow pushes the air rod 302 to extend. Multiple sealing rings 303 fitted on the outer surface of the air rod 302 fit tightly against the inner shell 304 to ensure the airtightness of the air cylinder 301 and prevent airflow leakage from affecting the supporting force. When the air rod 302 extends, it lifts the support block 307. The support block 307 at the end of the ventilation pipe 305 fits against the tunnel rock surface or the grouted cement layer to achieve stable support. At the same time, some airflow passes through the ventilation pipe 305. 5. Air is blown directly into the cement layer from the support block 307 to dry it. The ventilation holes 101 on the surface of the steel plate bracket 1 assist in heat dissipation and accelerate cement curing. Through the above technical solution, the air-driven support can adapt to the stress requirements of different areas of the tunnel by adjusting the air pressure of the air pump 4. The sealing ring 303 ensures the stability of the support force. The built-in ventilation pipe 305 avoids the airflow from interfering with the grouting layer, realizing the integration of support and air drying, improving the efficiency and stability of tunnel reinforcement. The ventilation and drying improve the stability of cement drying, solve the problem of the traditional surface drying with dry outside and wet inside, accelerate the cement curing efficiency, and shorten the construction cycle.
