Description

Technical Field

[0001] This invention relates to the field of karst tunnel cleaning equipment technology, and specifically to a karst tunnel drainage and dredging device. Background Technology

[0002] Due to the unique geological characteristics of the western region, many karst tunnels have been built in the mountainous areas to improve transportation convenience and thus promote economic and cultural exchanges and cooperation between different regions.

[0003] The uneven and irregular development of karst formations presents a series of challenges to the construction of karst tunnels, the most common being water and mud inrushes. In actual construction, karst tunnels are generally constructed along slopes, but this can easily lead to blockages in the tunnel's drainage system.

[0004] Based on the causes of blockages in karst tunnel drainage systems, the blockages are classified into two categories: non-crystalline blockages and crystalline blockages. Non-crystalline blockages in tunnel drainage systems are mainly related to construction and design defects, and will not be discussed here. Crystalline blockages, on the other hand, are mainly related to various factors such as CO2 partial pressure, temperature, and hydrodynamics. However, current measures for addressing crystalline blockages in tunnel drainage systems are not ideal, and a more reasonable technical solution is needed to solve the existing technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a drainage and dredging device for karst tunnels, so as to solve the problem that the existing treatment measures for the crystallization blockage of tunnel drainage systems are not ideal.

[0018] The guide tube is provided with a flow guiding structure, which is connected to the injection hole to cause the gas-liquid mixture in the injection chamber to aggregate.

[0019] The partition wall is also provided with a booster pipe extending to the flow guide structure, and the booster pipe is provided with booster holes that are respectively connected to the airflow cavity and the flow guide structure.

[0020] In one possible design, the flow guiding structure includes a first conical hopper and a second conical hopper connected sequentially to the guide tube. The first conical hopper has a first conical hole and a second conical hole. The end of the first conical hopper is inserted into the second conical hole.

[0021] In one possible design, the cavity of the seat body is provided with a stop platform with an annular cross-section, the stop platform being eccentrically positioned relative to the liquid inlet; the stop platform has a height difference, including a high portion near the liquid operating member and a low portion near the guide tube, the height of the high portion being higher than the height of the low portion; the liquid inlet is provided with an adjusting ball, the liquid operating member being movably connected to the seat body and pressing against the adjusting ball;

[0022] The injection chamber has a cleared state and a blocked state; in the blocked state, the adjusting ball is coaxially arranged with the inlet hole, and the spherical surface of the adjusting ball can abut against the high position and the low position to stop the flow of liquid; in the cleared state, the liquid operating member presses the adjusting ball to move, so that a gap is formed between the high position and the spherical surface of the adjusting ball, so that liquid can flow.

The limiting seat is fixedly disposed in the base body, and the base body is provided with a threaded hole. The liquid operating lever is provided with a screw adapted to the threaded hole. The liquid operating lever is sealed to the base body, and the screw is screwed into the threaded hole. When the liquid operating lever rotates, the screw can abut against the adjusting ball.

[0024] In one possible design, the gas operating component includes a gas operating rod and a pressure rod; a positioning cylinder is provided in the airflow cavity, one end of which is connected to the base body and the other end is fixedly connected to the partition wall;

[0025] One end of the gas operating lever is movably connected to the base, and the other end is fitted with a flow-limiting seat; the diameter of the flow-limiting seat is larger than the diameter of the positioning cylinder;

[0026] The positioning cylinder is also provided with a flow plate, which has air holes for gas flow; the gas operating rod is inserted into the middle hole of the flow plate and connected to the pressure rod.

[0027] The booster pipe is fixedly connected to the positioning cylinder, and the booster pipe extends into the first conical hole of the flow guiding structure;

[0028] The airflow cavity has an open state and a blocked state. In the blocked state, the gas operating rod is pushed inward so that the flow limiting seat blocks the positioning cylinder and the pressure rod blocks the pressurizing hole. In the open state, the gas operating rod is pulled outward so that the pressure rod moves away from the pressurizing hole and the flow limiting seat moves away from the positioning cylinder, and the gas is introduced into the pressurizing hole along the air hole.

[0032] One end of the support rod is rotatably connected to the base, and the other end is rotatably connected to the operating handle; when the operating handle is flipped, the connecting body can move relative to the crossbar, so that the connecting body can drive the gas operating lever to move.

[0033] In one possible design, the guide tube is provided with a flow guide seat and a flow divider seat. The flow guide seat has a third conical hole, the small-diameter end of which faces the flow guide structure, and the large-diameter end of which faces the flow divider seat. The flow divider seat has a plurality of jet channels formed thereon so that the gas-liquid mixture is discharged from the jet channels.

[0034] In one possible design, the karst tunnel drainage and dredging equipment further includes a feeding device communicatively connected to the controller. The feeding device includes a container and a drain pipe connected to the container. A control valve is provided on the drain pipe. The controller is used to control the opening and closing of the drain pipe so as to allow carbonic anhydrase preset in the container to be added to the drain pipe through the drain pipe.

[0035] Using the above technical solution, based on the detection results of the deposits on the drain pipe wall by the detection device, a grinding device can be deployed into the drain pipe to grind away the deposits and complete the cleaning work. Afterwards, a high-pressure jetting device can be activated to output high-pressure fluid, further breaking down the deposits with the high-pressure impact force, or blowing them away from the inner wall of the drain pipe.

Detailed Implementation

[0041] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that while the description of these embodiments is intended to aid in understanding the invention, it does not constitute a limitation thereof. The specific structural and functional details disclosed herein are only for describing exemplary embodiments of the invention. However, the invention can be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0042] According to a first aspect of this disclosure, a drainage and dredging device for karst tunnels is provided. Wherein, Figure 1 and Figure 2 One specific implementation is shown.

[0043] See Figure 1 and Figure 2As shown, the karst tunnel drainage and dredging equipment includes: a detection device for detecting basic information about deposits in the tunnel drainage pipe, including the location, geometry, thickness, and hardness of the deposits; a grinding device for grinding the deposits adhering to the inner wall of the drainage pipe; a high-pressure jetting device for blowing away the deposits adhering to the inner wall of the drainage pipe with high-pressure fluid; and a controller, communicatively connected to the detection device, grinding device, and high-pressure jetting device, which controls the grinding device and high-pressure jetting device to perform corresponding actions based on the received basic information about the deposits.

[0044] In one embodiment provided in this disclosure, the high-pressure injection device includes: an injection seat 1, which has an airflow chamber 103, an injection chamber 104 connected to the airflow chamber 103, and an injection hole for discharging high-pressure fluid. The airflow chamber 103 is located at the upstream end of the injection chamber 104, and the injection hole is located at the downstream end of the injection chamber 104, so that the fluid can be ejected from the injection hole after flowing from the airflow chamber 103 to the injection chamber 104; a jet vacuum pump connected to one side of the injection seat 1 for introducing high-pressure gas into the injection chamber 104; an injection pump connected to the other side of the injection seat 1 for introducing high-pressure liquid into the injection chamber 104 so as to mix with the high-pressure gas; a gas operating member 2 extending to the airflow chamber 103 for controlling the closing and opening of the airflow chamber 103; and a liquid operating member 3 extending to the injection chamber 104 for controlling the closing and opening of the injection chamber 104.

[0045] Based on the structure of the high-pressure jetting device, the jet vacuum pump and the jet pump can respectively introduce fluid and liquid, so that the two are mixed in the injection chamber 104 and then ejected. This enhances the breaking effect on the attached material, allowing the attached material to be effectively broken and detached from the pipe wall of the drain pipe under the impact of the high-pressure gas-liquid mixture. The liquid operating component 3 can control the opening and closing of the injection chamber 104, thereby achieving the interception and unblocking of the liquid; while the gas operating component 2 can correspondingly control the opening and closing of the gas flow chamber 103, thereby achieving the interception and unblocking of the gas.

[0046] When the injection chamber 104 is blocked, the fluid discharged from the injection hole is only gas; when the airflow chamber 103 is blocked, the fluid discharged from the injection hole is only liquid; when both the injection chamber 104 and the airflow chamber 103 are open, the discharged fluid is a gas-liquid mixture. In actual operation, the output state of the fluid can be changed by operating the gas operating component 2 and the liquid operating component 3, which has good flexibility and practicality.

[0047] Using the above technical solution, based on the detection results of the deposits on the drain pipe wall by the detection device, a grinding device can be deployed into the drain pipe to grind away the deposits and complete the cleaning work. Afterwards, a high-pressure jetting device can be activated to output high-pressure fluid, further breaking down the deposits with the high-pressure impact force, or blowing them away from the inner wall of the drain pipe. By pre-detecting the deposit morphology, initially breaking down hard deposits, and then deeply breaking them down and blowing them away from the drain pipe, the removal effect of deposits at the drain pipe opening can be guaranteed, completely solving the drain pipe blockage problem and restoring the basic function of the drain pipe.

[0048] This high-pressure jetting device can blow air at a high pressure onto the tunnel drainage pipe, using the high pressure to promptly remove sediment, silt, and surrounding rock fragments adhering to the tunnel drainage pipe wall, thereby extending the service life of the drainage pipe.

[0049] It should be noted that in this disclosure, "inner" and "outer" refer to the inner and outer sides relative to the outline of the component. The ordinal numbers such as "first" and "second" used in the text are only used to distinguish one feature from another, and do not have importance or order, and should not be interpreted as limitations on the technical features.

[0050] It should be noted that the jet vacuum pump is equipped with a conventional air pump capable of outputting high-pressure gas; while the ejector pump is equipped with a conventional hydraulic pump. Those skilled in the art can flexibly configure different types or specifications of fluid pumps according to actual needs.

[0051] In one exemplary embodiment provided in this disclosure, the injection seat 1 includes a seat body 11 and a guide tube 12 connected in sequence. The seat body 11 is provided with an air inlet 101, a liquid inlet 102, and a cavity. The air inlet 101 is disposed at the upper end of the cavity, and the liquid inlet 102 is disposed at the lower end of the cavity. A partition wall 13 is formed in the cavity. Along the direction of fluid flow, the partition wall 13 has a first blocking surface and a second blocking surface opposite to each other. The area between the air inlet 101 and the first blocking surface is formed as an airflow cavity 103. The cavity wall of 03 has a first curved surface, and the first curved surface protrudes towards the gas operating member 2; the area between the liquid inlet 102 and the second blocking surface is formed as the liquid injection cavity 104, the cavity wall of the liquid injection cavity 104 has a second curved surface, and the second curved surface protrudes towards the guide tube 12; the guide tube 12 is provided with a flow guiding structure, which is used to aggregate the gas-liquid mixture in the liquid injection cavity 104; the partition wall 13 is also provided with a pressure boosting pipe 15 extending to the flow guiding structure, and the pressure boosting pipe 15 is provided with pressure boosting holes that are respectively connected to the gas flow cavity 103 and the flow guiding structure.

[0052] The design based on the first curved surface facilitates the gathering and flow of gas towards the pressurization orifice. After being ejected from the orifice, the gas is guided into the flow-guiding structure. Simultaneously, the design based on the second curved surface allows the liquid to flow towards the flow-guiding structure, gradually converging during the flow process before being guided into the structure. This allows both gas and liquid to converge simultaneously within the flow-guiding structure. The aggregation effect of the flow-guiding structure promotes thorough mixing of the gas-liquid mixture, ultimately resulting in high-pressure ejection from the structure, thus achieving a pressurization effect and ensuring pressure stability during continuous high-pressure fluid injection.

[0053] In one embodiment provided in this disclosure, the flow guiding structure includes a first conical hopper 4 and a second conical hopper 5 sequentially connected to the guide tube 12. The first conical hopper 4 has a first conical hole and a second conical hole. The end of the first conical hopper 4 is inserted into the second conical hole. The centerlines of the first and second conical holes are parallel to the centerline of the guide tube 12, which helps the fluid to flow along the same straight line, reducing channel resistance while ensuring pressure stability. The large-diameter end of the first conical hole faces the injection chamber 104, thereby guiding the liquid to converge. In this way, a multi-stage polymerization and pressurization structure can be formed, thereby ensuring the pressure stability of the mixed fluid during injection.

[0054] Specifically, the guide tube 12, the first conical hopper 4, and the second conical hopper 5 are integrally formed, thereby ensuring the connection strength between them, ensuring the stability of the pressure, and facilitating the molding and manufacturing process.

[0055] In other embodiments, the first conical bucket 4 and the second conical bucket 5 may be welded to the guide tube 12.

[0056] In one embodiment provided in this disclosure, a stop plate 14 with an annular cross-section is provided in the cavity of the seat 11. The stop plate 14 is eccentrically arranged relative to the liquid inlet hole. The stop plate 14 has a height difference, including a high part near the liquid operating member 3 and a low part near the guide tube 12. The height of the high part is higher than the height of the low part. An adjusting ball 6 is provided in the liquid inlet hole. The liquid operating member 3 is movably connected to the seat 11 and presses against the adjusting ball 6.

[0057] The injection chamber 104 has a clearing state and a blocking state. In the blocking state, the adjusting ball 6 is coaxially arranged with the inlet hole, and the spherical surface of the adjusting ball 6 can abut against the high position and the low position to stop the flow of liquid. In the clearing state, the liquid operating member 3 presses the adjusting ball to move so that a gap is formed between the high position and the spherical surface of the adjusting ball 6 so that the liquid can flow.

[0058] In this way, the unobstructed state of the injection chamber 104 can be changed by adjusting the position of the liquid operating component 3, and the gap size can be adjusted by moving the liquid operating component 3 slightly, thereby changing the flow rate and velocity of the liquid, so that the liquid and gas have different mixing ratios.

[0059] In one possible design, the liquid operating component includes a liquid operating rod 31 and a limiting seat 32. The limiting seat 32 is fixedly disposed in the seat body 11, and the seat body 11 is provided with a threaded hole. The liquid operating rod 31 is provided with a screw that is adapted to the threaded hole. The liquid operating rod 31 is sealed to the seat body 11, and the screw is screwed into the threaded hole. When the liquid operating rod 31 rotates, the screw can abut against the adjusting ball 6, thereby adjusting the position of the adjusting ball, thereby changing the gap size and adjusting the liquid flow state.

[0060] Specifically, the liquid operating lever 31 is connected to the motor drive, so that the power output of the motor drives the liquid operating lever 31 to rotate, thereby changing the position of the adjusting ball 6.

[0061] Of course, in other embodiments, a handle 33 can be provided at the end of the liquid operating lever 31, so that the liquid operating lever 31 can be driven to rotate manually, thereby adjusting the position of the adjusting ball 6.

[0062] In one specific embodiment, the gas operating component 2 includes an operating handle 23, a gas operating rod 21, and a pressing rod 22; a positioning cylinder 71 is provided in the airflow cavity 103, one end of the positioning cylinder 71 is connected to the base 11, and the other end is fixedly connected to the partition wall 13; one end of the gas operating rod 21 is movably connected to the base 11, and the other end is sleeved with a flow-limiting seat; the diameter of the flow-limiting seat is larger than the diameter of the positioning cylinder 71, so that when the flow-limiting seat is away from the positioning cylinder 71, gas can enter the positioning cylinder 71 through the gap; and when the flow-limiting seat is in contact with the positioning cylinder 71, a sealing structure can be formed, thereby preventing gas from entering the positioning cylinder 71.

[0063] The positioning cylinder 71 is also provided with a flow plate 72, which has air holes for gas flow. The gas operating rod 21 is inserted into the middle hole of the flow plate 72 and connected to the pressure rod 22. The middle hole can play a certain role in straightening the gas operating rod 21, so that the axis of the gas operating rod 21 can coincide with the axis of the positioning cylinder 71, which is beneficial to enable the gas operating rod 21 to move smoothly, thereby driving the pressure rod 22 to move smoothly.

[0064] Specifically, multiple air holes are arranged in a circular array on the flow plate 72, which helps to make the gas flow evenly through the air holes and ensures the stability of the pressure when the gas is injected into the pressurization hole.

[0065] The booster pipe 15 is fixedly connected to the positioning cylinder 71 to ensure the reliability of their relative positions (specifically, they are connected by welding). The booster pipe 15 extends into the first conical hole of the flow guide structure, so that the high-pressure gas can be accurately injected into the first conical hole, thereby achieving a better boosting effect.

[0066] The airflow chamber 103 has an open state and a blocked state. In the blocked state, the gas operating rod 21 is pushed inward so that the flow limiting seat blocks the positioning cylinder 71 and the pressure rod 22 blocks the pressurization hole. In the open state, the gas operating rod 21 is pulled outward so that the pressure rod 22 moves away from the pressurization hole and the flow limiting seat moves away from the positioning cylinder 71, and the gas is introduced into the pressurization hole along the air hole.

[0067] To improve the limiting effect on the booster pipe 15, the karst tunnel drainage and dredging equipment also includes a guide cylinder 16. The guide cylinder 16 is fixedly connected to the partition wall 13 and coaxially sleeved around the booster pipe 15. The guide cylinder 16 has a guide hole adapted to the booster pipe 15, and a positioning and straightening seat is sleeved around the booster pipe 15 and inserted into the guide hole. The outer wall of the positioning and straightening seat abuts against the inner wall of the guide pipe 12, and the inner wall of the positioning and straightening seat abuts against the outer wall of the booster pipe 15. This design provides support and straightening for the position of the booster pipe 15, ensuring that the booster pipe 15 and the guide cylinder 16 remain coaxial, which facilitates the smooth flow of gas along the booster pipe 15.

[0068] In this disclosure, the positioning and straightening seat is provided with weight reduction holes, which are spaced apart along the circumference of the positioning and straightening seat.

[0069] In one embodiment provided in this disclosure, the gas operating component 2 further includes an operating handle 23, a crossbar 24, a connecting body 25, and a support rod 26. The crossbar 24 and the support rod 26 are respectively located on both sides of the base 11. The operating handle 23 is connected to the gas operating rod 21 through the connecting body 25. One end of the crossbar 24 is fixedly connected to the base 11, and the other end is inserted into the positioning hole of the connecting body 25. One end of the connecting body 25 is rotatably connected to the operating handle 23, and the other end is connected to the gas operating rod 21.

[0070] One end of the support rod 26 is rotatably connected to the base 11, and the other end is rotatably connected to the operating handle 23. When the operating handle 23 is flipped, the connecting body 25 can move relative to the crossbar 24, so that the connecting body 25 can drive the gas operating rod 21 to move, thereby adjusting the position of the gas operating rod 21 through this manual control method.

[0071] In other embodiments, the cylinder can be indirectly connected to the gas operating lever 21, thereby driving the gas operating lever 21 to move laterally through the power output of the cylinder, thereby changing the blocking state of the positioning cylinder 71 and the pressurization hole. The cylinder is communicatively connected to the controller.

[0072] In this disclosure, the guide tube 12 is provided with a flow guide seat 81 and a flow divider seat 82. The flow guide seat 81 has a third conical hole, the small diameter end of which faces the flow guide structure, and the large diameter end of which faces the flow divider seat 82. The flow divider seat 82 has multiple jet channels formed so that the gas-liquid mixture can be discharged from the jet channels, thereby allowing the gas-liquid mixture to be sprayed out in a split manner, thereby increasing the crushing area of ​​the attached material and improving the removal efficiency under stable output pressure.

[0073] Specifically, the jet channel is configured with a variable diameter structure, and the channel size gradually decreases along the direction of fluid injection.

[0074] Specifically, the jet channel has a spiral structure, which allows the discharged gas-liquid mixture to form a swirling flow, thereby improving the removal effect on the attached substances.

[0075] In one embodiment of this disclosure, the karst tunnel drainage and dredging equipment further includes a feeding device that is communicatively connected to the controller. The feeding device includes a container and a drain pipe connected to the container. A control valve is provided on the drain pipe. The controller is used to control the opening and closing of the drain pipe so that carbonic anhydrase preset in the container can be added to the drain pipe through the drain pipe.

[0076] Introducing bacteria that efficiently produce carbonic anhydrase (CA) into the pipeline promotes greater CO2 conversion and facilitates the fusion of precipitates and crystals produced in the drainage pipes. Electronic monitoring equipment checks the CA bacteria content, allowing for timely adjustments to the bacterial species and quantity. Timely addition of scale inhibitors, such as HEDP, is also crucial.

[0077] In other embodiments, the karst tunnel drainage and dredging equipment further includes a dispensing device containing an acidic solvent or acidic solution, capable of introducing the acidic solvent or acidic solution into the drain pipe to adjust the pH value of the water in the drain pipe. In one embodiment, the pH of the water in the drain pipe is set to <6.4, which can dissolve precipitated crystals.

[0078] Alternatively, drain the water from the drain pipe and then introduce a solution with a pH < 6 into the area of ​​crystallization in the drain pipe, thereby dissolving the crystals.

[0079] In this disclosure, the detection device includes a ground-penetrating radar (GPR). This GPR can transmit pulsed high-frequency or very-high-frequency electromagnetic waves into the drainage pipe using specific instruments. When the electromagnetic waves encounter an underground target with a difference in electrical properties during propagation through the medium, they are reflected and received by a receiving antenna upon return. Based on the radar waveform, two-way time, and intensity parameters received by the receiving antenna, the spatial location, electrical properties, structure, and geometry of the attached material (e.g., crystals) can be inferred. Utilizing the principle of GPR detection, combined with the electrical differences in the media such as tunnel lining, reinforcing steel, drainage pipes, sediment, silt, and surrounding rock fragments, the specific location, shape, and scale of blockages (e.g., sediment) within the tunnel drainage pipe can be detected, allowing for targeted treatment.

[0080] Since ground-penetrating radar is existing technology, it will not be described in detail here.

[0081] In this disclosure, the controller is an integrated circuit chip with signal processing capabilities. In implementation, the aforementioned functions can be accomplished through integrated logic circuits in the controller's hardware or through software instructions.

[0082] In other embodiments, the controller described above can also be a general-purpose processor, including a central processing unit (CPU), a network processor (NP), etc.; it can also be a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, or discrete hardware components. Those skilled in the art can obtain this through conventional improvements based on existing technology.

[0083] Furthermore, the detection device, grinding device, high-pressure injection device, feeding device, and controller can transmit data via various well-known wireless transmission protocols in the art, such as GPRS, WiFi, and Bluetooth, thereby reducing the need for signal cable laying. Of course, wired data transmission via communication cables is also possible, and this invention does not limit this approach.

[0084] Finally, it should be noted that this invention is not limited to the optional embodiments described above, and anyone can derive other various forms of products under the guidance of this invention. The specific embodiments described above should not be construed as limiting the scope of protection of this invention, which should be determined by the claims, and the specification can be used to interpret the claims.
