Description

Technical Field

[0001] This invention is mainly used for the treatment of water hazards caused by large channels, large flow rates, and high water pressure in mining, railway, highway, and water conservancy production processes. Specifically, it relates to an integrated device and operating method for rapid ground drilling, sealing, and recovery of large cross-section water inrush channels. Background Technology

[0002] Mine flooding is one of the five major safety hazards in mine construction and production, especially mine water inrush, which often causes huge casualties and property losses. Mine water inrushes frequently result in mass deaths and injuries. Currently, the common solution for coal mine water inrush accidents in my country is to simultaneously implement mine drainage and grouting to block the water. Grouting to block the water is generally carried out in two phases: the first phase involves sealing the water-carrying roadway to convert the dynamic water flow to stagnant water; the second phase involves treating the water-carrying roadway to completely eliminate the water hazard. The first phase of sealing the water-carrying roadway usually involves drilling holes directly into the roadway on the surface, filling the roadway with aggregates and other auxiliary materials to change the groundwater flow from pipe flow to seepage flow, followed by grouting for consolidation. When facing water-carrying roadways with high flow velocities, directly drilling and filling with aggregates is easily dispersed and difficult to solidify, resulting in a low success rate. Furthermore, the entire treatment process requires first converting to seepage flow and then grouting, which involves a large workload and a long treatment period. There is no limit to the grouting area during grouting, which easily leads to waste of grouting fluid. Therefore, traditional grouting plugging technology has poor stability, with a low success rate and poor stability when facing high water pressure, large flow rate, and large channel water flow.

[0003] To address the aforementioned issues, a new method was introduced in "Zhu Mingcheng, Key Technologies and Equipment for Efficient Sealing of Water Inrush in Large-Channel Water-Flowing Boreholes with Controlled Grouting [J], Coal Geology and Exploration, 2015, 43(4): 55-58". This method utilizes a specific controlled grouting drill bit to send a grout-preserving bag into the water-flowing roadway, and then grouts are injected into the bag within the roadway. The pressure generated by the grouting removes the bag from the controlled grouting drill bit, leaving it in the roadway. Compared to the aforementioned method, this approach avoids the situation where the grout is washed away before it solidifies to a certain extent, thus improving the success rate. However, for high-pressure, high-flow-rate, and large-channel flowing water, this method still suffers from the same problem of the high-speed water flow washing away the grout-preserving bag, and the problem remains unresolved.

[0004] The integrated sealing device for water inrush drilling, airbags, and grouting in large-section water inrush channels, as described in patent CN202022290244.1, also suffers from problems such as the inability of the support structure to adapt to irregular water inrush tunnels, the inability to achieve integrated drilling and sealing, and the inability to recover the sealing device. To address these issues, it is imperative to develop an integrated device and operating method for rapid ground drilling, sealing, and recovery of large-section water inrush channels. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated device and operating method for rapid drilling, sealing, and recovery of large-section water inrush channels. This device can quickly control high-pressure, high-flow-rate, and large-channel dynamic water within a local area of ​​the water inrush channel, providing a new approach and method for water hazard prevention in coal mines and underground engineering.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0007] An integrated device for rapid drilling, plugging, and recovery of large-section water inrush channels includes a rapid integrated drill bit, an adaptive plugging device, a detachable drill rod, a three-channel drilling device, and a control system. One end of the detachable drill rod is snapped into the rapid integrated drill bit, and the other end is threaded into the three-channel drilling device. The adaptive plugging device is located inside the detachable drill rod, with one end threaded into the rapid integrated drill bit and the other end snapped into the detachable drill rod. When drilling reaches the water inrush channel, the detachable drill rod is rotated upwards to detach from the rapid integrated drill bit, exposing the adaptive plugging device outside. Under the control of the control system, the adaptive plugging device rapidly plugs the irregular water inrush channel. After plugging is completed, the detachable drill rod is lowered and rotated under the control system to reconnect with the rapid integrated drill bit, enabling the recovery of both the rapid integrated drill bit and the adaptive plugging device.

[0008] Preferably, the adaptive plugging device includes a device fixing pipe connected at one end to a fast integrated drill bit, a pneumatically controlled shears, a plugging airbag, a pneumatically controlled folding telescopic rod base, a pneumatically controlled folding telescopic rod on the pneumatically controlled folding telescopic rod base, a control air pump, a flexible grouting pipe connected to the plugging air, a flexible inflation and deflation pipe, and a flexible sealing power pipe located within the device fixing pipe; the three-channel drilling device includes a three-channel drill rod, a wind control power pipe, a grouting pipe, and an inflation and deflation pipe located within the three-channel drill rod; the grouting pipe, the inflation and deflation pipe, and the wind control power pipe pass through the device fixing pipe and can be detached. The drill rod is connected to the grouting pipe, the air inflation and exhaust pipe, and the pneumatic control power pipe respectively. The operation and control system controls the air pump through the pneumatic control power pipe and the pneumatic control power pipe, so that the pneumatically controlled folding telescopic rod extends out of the device's fixed pipe to form a protective rod. The operation and control system inflates the sealing airbag through the air inflation and exhaust pipe and then grouts the sealing airbag through the grouting pipe and the grouting pipe. After grouting is completed, the control system controls the air pump to control the pneumatically controlled shears to detach the sealing airbag. The control system controls the pneumatically controlled folding telescopic rod to return to the device's fixed pipe and controls the detachable drill rod to connect with the quick-connect integrated drill bit.

[0009] Preferably, the rapid integrated drill bit includes a drill bit body and a slot provided on the drill bit body, and a connecting block is provided on the detachable drill rod. The rapid integrated drill bit and the detachable drill rod are detachably connected through the cooperation of the slot and the connecting block.

[0010] Preferably, the slot is an L-shaped slot, which ensures easy separation and stable connection between the drill rod and the quick-connect drill bit during drilling and retrieval.

[0011] Preferably, the adaptive plugging device further includes a limiter disposed at the other end of the device fixing tube, the limiter ensuring that the adaptive plugging device and the detachable drill rod will not separate when the drill rod is pulled back.

[0012] Preferably, a three-channel drill rod is formed by opening a wind control power pipe, a grouting pipe, and an air filling and exhaust pipe inside the solid drill rod.

[0013] Preferably, the surface of the detachable drill rod is provided with a detachable external thread, which enables external drilling.

[0014] Based on the above-mentioned device, the present invention also provides an operation method for an integrated device for rapid drilling, sealing, and recovery of large-section water inrush channels, comprising the following steps:

[0015] S1. Drill the above-mentioned device to the location of the water inrush channel by ground drilling;

[0016] S2. Open the L-shaped slot, separate the detachable drill pipe from the adaptive sealing device, and return the drill pipe until it contacts the limit switch at the end of the adaptive sealing device, thus exposing the adaptive sealing device.

[0017] S3. Using the control system, through the wind control power pipeline and wind control power pipe, control the air pump, open the pneumatic control folding telescopic rod, so that it extends out of the device fixing pipe to form a support in the water inrush channel.

[0018] S4. Using the control system, inflate the sealing airbag through the inflation and deflation pipes and the inflation and deflation tubes, open the sealing airbag and expand it to match the cross-section of the water inrush channel to form a water inrush channel sealing airbag attached to the support.

[0019] S5. Use grouting pipes and grouting tubes to inject cement mortar into the sealing airbag to displace the gas in the sealing airbag. After the cement mortar solidifies to form stone solid, it will eventually form a filling body to seal the water inrush channel and control the large cross-section water inrush within a local area.

[0020] S6. Using pneumatically controlled shears, separate the sealing airbag from the adaptive sealing device, operate the pneumatically controlled folding telescopic rod to return to the device's fixed tube, and drill back to connect the connecting block that can be detached from the drill rod and the L-shaped slot of the quick integrated drill bit to retrieve the device.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) This device uses a bracket to fix the sealing airbag in the water inrush channel, which prevents the sealing airbag from being washed away by high-pressure water after grouting, thereby improving the success rate of grouting and water plugging and improving the stability of this device.

[0023] (2) This device uses a connecting pin to connect the sealing device to the drill rod, which avoids soil or rock entering the sealing device through the outlet of the pneumatically controlled folding telescopic rod during the drilling process, thus affecting the normal use of the sealing device.

[0024] (3) This device first inflates the sealing airbag using the inflation and deflation pipes and inflation and deflation pipes, so that the sealing airbag matches the cross-section of the water inrush channel. Then, the gas is replaced with cement mortar through the grouting pipes and grouting pipes, so that the sealing airbag after grouting can also match the cross-section of the water inrush channel, so that the water in the water inrush channel can be completely sealed in one go, improving the success rate of grouting and water blocking, and completing the task in one go, simplifying the operation.

[0025] (4) This device utilizes the fact that the drill rod surface can be detached from the external thread of the drill rod to achieve external discharge drilling. After drilling to the position of the water inrush channel, the device can re-drill a part and then directly perform grouting and sealing, thus achieving integrated drilling and sealing, improving the efficiency of grouting and water plugging projects, and simplifying operation.

[0026] (5) This device uses pneumatically controlled shears to separate the sealing airbag from the adaptive sealing device and to recover the adaptive sealing device, thus saving the cost of grouting sealing project;

[0027] (6) This method is simple to operate, has a high success rate of grouting and water plugging, and is highly flexible. It is suitable for rapid grouting and sealing of water channels with high water pressure, large flow rate and large moving water. Attached Figure Description

The rapid integrated drill bit 1 is connected to one end of the adaptive plugging device 2, and one end of the detachable drill rod 3 is connected to the three-channel drilling device. During drilling, the adaptive plugging device 2 is located inside the detachable drill rod 3, with the other end of the detachable drill rod 3 connected to the rapid integrated drill bit 1. During plugging, the detachable drill rod 3 is controlled to detach from the rapid integrated drill bit 1, exposing the adaptive plugging device 1 outside the detachable drill rod 3. The control system 5 is used to achieve plugging by the adaptive plugging device 2. After plugging is completed, the detachable drill rod 3 is controlled to connect back to the rapid integrated drill bit 1, so that the adaptive plugging device 2 is located inside the detachable drill rod 3, completing the recovery process.

[0052] The specific rapid integrated drill bit 1 includes a drill bit body, an L-shaped chuck 1-3, and a connecting internal thread 1-4. The drill bit body includes a wedge-shaped drill bit 1-1 and a wedge-shaped drill bit holder 1-2. The L-shaped chuck 1-3 is set on the wedge-shaped drill bit holder 1-2, and the connecting internal thread 1-4 is set in the center of the wedge-shaped drill bit holder 1-2.

[0053] The adaptive sealing device 2 includes a pneumatically controlled shears 2-1, a sealing airbag 2-2, a pneumatically controlled folding telescopic rod 2-3, a control air pump 2-4, a limiter 2-5, a grouting pipe 2-6, an inflation / exhaust valve 2-7, a pneumatically controlled folding telescopic rod base 2-8, a connecting boss thread 2-9, a device fixing pipe 2-10, a pneumatically controlled power pipe 2-11, and a hose connecting external thread 2-12. Figure 4 , 5 As shown, the connecting boss thread 2-9 is located at one end of the device fixing tube 2-10, and the device fixing tube 2-10 is connected to the connecting internal thread 1-4 located on the quick integrated drill bit 1 via the connecting boss thread 2-9. Figure 6 , 7As shown, the pneumatically controlled shears 2-1, sealing airbag 2-2, pneumatically controlled folding telescopic rod 2-3, control air pump 2-4, grouting pipe 2-6, inflation and deflation pipe 2-7, pneumatically controlled folding telescopic rod base 2-8, and air control power pipe 2-11 are all located inside the device fixing pipe 2-10. A limiter 2-5 is installed at one end of the device fixing pipe 2-10 to ensure that the adaptive sealing device 2 and the detachable drill rod 3 do not detach during drilling back. Figure 8 , 9 As shown, the pneumatically controlled folding telescopic rod 2-3 is mounted on the pneumatically controlled folding telescopic rod base 2-8. The grouting pipe 2-6, inflation / exhaust pipe 2-7, and pneumatic control power pipe 2-11 all use flexible hoses. The pneumatic control power pipe 2-11 is connected to the control air pump 2-4, providing power to the control air pump. The control air pump 2-4 is connected to the pneumatically controlled folding telescopic rod 2-3 and the pneumatically controlled scissors 2-1, used to control the extension and retraction of the pneumatically controlled folding telescopic rod 2-3, control the opening and closing of the pneumatically controlled scissors, separate the sealing airbag and the sealing device, and achieve adaptive sealing device retrieval. The inflation / exhaust pipe 2-7 and the grouting pipe 2-6 are connected to the sealing airbag 2-2.

[0054] The device fixing tube 2-10 is equipped with pneumatically controlled folding telescopic rod 2-3 outlets on both sides and a sealing airbag 2-2 outlet on the front. When the detachable drill rod 3 separates from the quick-connect integrated drill bit 1, the control air pump 2-4 applies air pressure to push the pneumatically controlled folding telescopic rod 2-3 out from the outlets on both sides, forming an umbrella-shaped protective bracket. A slot is provided on the pneumatically controlled folding telescopic rod base 2-8, which is used to fix the umbrella-shaped protective bracket when it extends out of the device fixing tube 2-10. In this embodiment, the end of the pneumatically controlled folding telescopic rod 2-3 is arrow-shaped, which can fix the pneumatically controlled folding telescopic rod to the channel surface. When the pneumatically controlled folding telescopic rod is opened, the sealing airbag 2-2 is inflated by controlling the inflation and exhaust pipe 2-7, so that it opens from the front outlet and expands to match the cross-section of the water inrush channel, forming an inflated sealing airbag attached to the pneumatically controlled folding telescopic rod 2-3. Under the grouting action of the grouting pipe and the exhaust action of the inflation and exhaust pipe, the gas in the inflated sealing airbag 2-2 is replaced by cement mortar.

[0055] The detachable drill rod 3 is externally equipped with a detachable drill rod external thread 3-1, an external discharge soil chute 3-2, and a connecting block 3-3. The detachable drill rod external thread 3-1 enables external discharge drilling, such as... Figure 4 , 5 As shown, during drilling, the drill rod 3 can be detached and maintained connected to the L-shaped slot 1-3 via the connecting block 3. For example... Figure 2As shown, after drilling to the appropriate position, the drill rod is pulled back, causing the connecting block 3-3 to separate from the L-shaped slot 1-3, allowing the detachable drill rod 3 to separate from the quick-connect integrated drill bit. Due to the presence of the limiter 2-5, the detachable drill rod will not detach from the adaptive sealing device 2. After sealing is completed, the detachable drill rod 3 is controlled to connect the connecting block 3 to the L-shaped slot 1-3.

[0056] The three-hole drilling device 4 includes a three-hole drill rod 4-1, a ventilation and power pipe 4-2, a grouting pipe 4-3, and an air-filling and venting pipe 4-4 located inside the three-hole drill rod 4-1, an external thread 4-5, an external discharge trough 4-6, a pull-ring switch protrusion 4-7, and a pull-ring switch groove 4-8. In this embodiment, the three-hole drill rod 4-1 is formed by opening the ventilation and power pipe 4-2, the grouting pipe 4-3, and the air-filling and venting pipe 4-4 inside a solid drill rod. Each of the three pipes is equipped with an internal pipe connection thread 4-9, while the grouting pipe 2-6, the air-filling and venting pipe 2-7, and the sealing power pipe 2-11 are each equipped with a matching external hose connection thread 2-12. The internal pipe connection thread 4-9 and the external hose connection thread 2-12 ensure a one-to-one connection between the three pipes and the three hoses. The detachable drill rod 3 is connected to the three-hole drill rod 4-1 by a threaded connection. The other two adjacent three-hole drill rods 4-1 are connected by matching pull ring switch protrusions 4-7 and pull ring switch grooves 4-8.

[0057] The control system 5 specifically includes a grouting device 5-1, an air injection device 5-2, and a control device 5-3. The grouting device 5-1 is connected to the grouting pipe 4-3 and is used to control the grouting process. The air injection device 5-2 is connected to the inflation and deflation pipe 4-4 and is used to control the inflation and deflation processes. The control device 5-1 is connected to the pneumatic power pipe 4-2 and is used to provide air pressures of different levels and control the control air pump 2-4.

[0058] This invention also provides an operation method for an integrated device for rapid drilling, sealing, and recovery of large-section water inrush channels, comprising the following steps:

[0059] S1. By drilling through the ground, the above-mentioned device is drilled to the position of the water inrush channel. At this time, it can be detached from the drill rod 3 and connected to the quick integrated drill bit 1. The adaptive sealing device 2 is located inside it. This way, the drilling process is not affected, and the adaptive sealing device can be protected.

[0060] S2, S2, Open L-shaped slots 1-3 to separate the detachable drill pipe from the adaptive sealing device. Drill back and lift the pipe until it contacts the limit switch at the end of the adaptive sealing device, exposing the adaptive sealing device.

[0061] S3. Using the control system 5, through the wind control power pipe 4-2 and the wind control power pipe 2-11, control the air pump 2-4 to open the pneumatic control folding telescopic rod 2-3 so that it extends out of the device fixing pipe 2-10 to form a protective support in the water inrush channel.

[0062] S4. Using the control system, inflate the sealing airbag 2-2 through the inflation and deflation pipe 4-4 and the inflation and deflation pipe 2-7, open the sealing airbag 2-2, and expand it to match the cross-section of the water inrush channel, forming a water inrush channel sealing airbag 2-2 attached to the support.

[0063] S5. Using grouting pipes 4-3 and 2-6, cement mortar is injected into the sealing airbag 2-2 to displace the gas in the sealing airbag 2-2. After the cement mortar solidifies to form a stone solid, it finally forms a filling body to seal the water inrush channel, controlling the large cross-section water inrush within a local area.

[0064] S6. Using pneumatically controlled shears, after the sealing is completed, the pneumatically controlled shears cut the airbag under the action of air pressure, separating the airbag from the drill rod. Control the pneumatically controlled folding telescopic rod to return to the fixed tube of the device, and drill back to the slot of the connecting block that can be detached from the drill rod and connected to the quick integrated drill bit for device recovery.

[0065] S6. Using pneumatically controlled shears 2-1, separate the sealing airbag 2-2 from the adaptive sealing device 2, and manipulate the pneumatically controlled folding telescopic rod 2-3 back into the device fixing tube 2-10. Drill back to the connecting block 3-3 that can be detached from the drill rod 3 and connect to the L-shaped slot 1-3 of the fast integrated drill bit 1 to retrieve the device.

[0066] When inflating the sealing airbag 2-2, first open the grouting pipe and the inflation and deflation pipe to inflate the sealing airbag. Under the action of air pressure, the sealing airbag opens through the airbag outlet. When the sealing airbag expands to match the cross-section of the water inrush channel, grout is injected into the sealing airbag through the grouting pipe. The inflation and deflation pipe is used as the exhaust pipe to displace the gas in the sealing airbag. When grout is discharged from the inflation and deflation pipe, the grouting is stopped.

An operating method for an integrated device for rapid drilling, sealing, and recovery of large-section water inrush channels, performed according to any one of claims 1-5, characterized in that: Includes the following steps: S1. Drill the above-mentioned device to the location of the water inrush channel by ground drilling; S2. Open the L-shaped slot, separate the detachable drill pipe from the adaptive sealing device, and return the drill pipe until it contacts the limit switch at the end of the adaptive sealing device, thus exposing the adaptive sealing device. S3. Using the control system, through the wind control power pipeline and wind control power pipe, control the air pump, open the pneumatic control folding telescopic rod, so that it extends out of the device fixing pipe to form a support in the water inrush channel. S4. Using the control system, inflate the sealing airbag through the inflation and deflation pipes and the inflation and deflation tubes, open the sealing airbag and expand it to match the cross-section of the water inrush channel to form a water inrush channel sealing airbag attached to the support. S5. Use grouting pipes and grouting tubes to inject cement mortar into the sealing airbag to displace the gas in the sealing airbag. After the cement mortar solidifies to form stone solid, it will eventually form a filling body to seal the water inrush channel and control the large cross-section water inrush within a local area. S6. Using pneumatically controlled shears, separate the sealing airbag from the adaptive sealing device, operate the pneumatically controlled folding telescopic rod to return to the device's fixed tube, and drill back to connect the connecting block that can be detached from the drill rod and the L-shaped slot of the quick integrated drill bit to retrieve the device.
