[0001] This invention relates to the field of mine roadway sealing technology, specifically to an adaptive high-strength roadway sealing device and roadway sealing method. Background Technology

[0002] A roadway sealing device is a device installed inside a mine roadway to temporarily or permanently seal it. It is used for optimizing and adjusting the mine ventilation system, preventing air leakage, preventing the leakage of toxic gases in disaster areas, and preventing the spread of fires and explosions. In related technologies, the roadway sealing device includes a support frame and an airbag. The support frame is used to support the roadway, and the airbag is located within the support frame to seal and release the space formed by the support frame. However, in the use of related technologies, gaps exist between the support frame and the roadway roof, and between the support frame and the sidewalls, preventing the roadway sealing device from completely sealing the roadway. Summary of the Invention

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention propose an adaptive high-strength roadway sealing device. This device has a first airbag fitted around the outer periphery of a side beam to seal the gap between the side beam and the roadway sidewall, and a second airbag fitted around the outer periphery of a top beam to seal the gap between the top beam and the roadway roof.

[0008] The first airbag extends along the vertical direction and is sleeved on the outer periphery of the side beam;

[0009] The second airbag extends along the first direction and is fitted around the outer periphery of the top beam;

[0010] A third airbag is connected to the top beam and / or at least two of the side beams, and the third airbag is located inside the opening to be sealed for sealing the opening.

[0011] The adaptive high-strength roadway sealing device of this invention is provided with side beams and top beams to form an opening to be sealed, and the opening to be sealed is sealed by a third airbag. At the same time, a first airbag is fitted around the outer periphery of the side beam to seal the gap between the side beam and the roadway sidewall, and a second airbag is fitted around the outer periphery of the top beam to seal the gap between the top beam and the roadway roof, so that the adaptive high-strength roadway sealing device of this invention can completely seal the roadway.

[0012] In some embodiments, the third airbag can move between a folded position and a blocking position.

[0013] In the folded position, the top of the third airbag is connected to the top of the top beam and / or the top of at least two of the side beams, the side beams having a midpoint in the vertical direction, and the bottom of the third airbag is connected to at least two of the side beams and located on the side of the midpoint facing the top beam.

[0014] At the occlusion position, the top of the third airbag is connected to the top of the top beam and / or the top of at least two of the side beams, and the bottom of the third airbag is connected to the bottom of at least two of the side beams.

[0015] In some embodiments, the top of the side beam is hinged to the top beam so that the side beam can rotate about a second direction relative to the top beam, the second direction being orthogonal to the vertical direction and the first direction.

[0016] In some embodiments, the top beam has a first protrusion and a second protrusion, and the side beam is rotatable between a first position and a second position. In the first position, one side of the side beam abuts against the first protrusion, and in the second position, the other side of the side beam abuts against the second protrusion.

[0017] In some embodiments, the angle between the centerline of the side beam and the centerline of the top beam is 90° to 135°.

[0018] In some embodiments, the adaptive high-strength tunnel sealing device further includes:

[0019] The mounting component is located inside the opening to be sealed, and the top end of the mounting component is connected to the top beam. The mounting component and the third airbag are arranged at intervals in the second direction.

[0020] A first telescopic member is disposed on the mounting member and is connected to a side beam located at the outermost end in the first direction to drive the side beam to rotate about the second direction.

[0021] A second telescopic member is disposed on the mounting member and is connected to another side beam located at the outermost end in the first direction to drive the other side beam to rotate about the second direction.

[0022] In some embodiments, the adaptive high-strength tunnel sealing device further includes a third telescopic member, wherein the side beam located at the outermost end in the first direction is provided with the third telescopic member, one end of the third telescopic member is located on the side of the side beam away from the opening to be sealed, and one end of the third telescopic member is retractable relative to the side beam along the first direction.

[0038] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0039] The following is for reference. Figures 1-2 This invention describes an adaptive high-strength roadway sealing device and a roadway sealing method according to embodiments of the invention.

[0040] like Figures 1-2 As shown, the adaptive high-strength roadway sealing device of this invention includes a side beam 1, a top beam 2, a first airbag 3, a second airbag 4, and a third airbag 5.

[0041] Side beam 1 extends vertically, and there are at least two side beams 1. Top beam 2 extends along the first direction (e.g., Figure 1 Extending in the left and right directions shown, the first direction is orthogonal to the vertical direction, the top beam 2 is connected to at least two side beams 1, and the top beam 2 is located on top of at least two side beams 1, forming an opening to be sealed between the top beam 2 and at least two side beams 1.

[0042] Specifically, the side beam 1 extends in the vertical direction, and there are two side beams 1. The two side beams 1 are arranged alternately in the horizontal direction. The top beam 2 extends in the horizontal direction. The left end of the top beam 2 is connected to the top of one side beam 1, and the right end of the top beam 2 is connected to the top of the other side beam 1, so that the two side beams 1 and the top beam 2 form a door-shaped frame. The internal space of the frame is the opening to be sealed.

[0043] The first airbag 3 extends vertically and is fitted around the outer periphery of the side beam 1. The second airbag 4 extends along the first direction and is fitted around the outer periphery of the top beam 2. The third airbag 5 is connected to the top beam 2 and / or at least two side beams 1, and is located within the opening to be sealed for sealing the opening.

[0044] Specifically, such as Figure 1 As shown, the first airbag 3 extends vertically and is fitted around the outer periphery of the side beam 1. In other words, the first airbag 3 is cylindrical. The cylindrical first airbag 3 can be a one-piece structure or a flat airbag connected to the side beam 1 by straps or adhesive tapes at both ends. Preferably, the dimension of the first airbag 3 in the vertical direction is greater than or equal to the dimension of the side beam 1 in the vertical direction. The second airbag 4 extends horizontally and is fitted around the outer periphery of the top beam 2. In other words, the second airbag 4 is cylindrical. The cylindrical second airbag 4 can be a one-piece structure or a flat airbag connected to the top beam 2 by straps or adhesive tapes at both ends. Preferably, the dimension of the second airbag 4 in the horizontal direction is greater than or equal to the dimension of the top beam 2 in the horizontal direction.

[0045] The third airbag 5 is located inside the frame formed by the side beam 1 and the top beam 2. The top of the third airbag 5 can be connected to the top beam 2, or the upper part of its left end can be connected to the left side beam 1, and the upper part of its right end can be connected to the right side beam 1. The lower part of the left end of the third airbag 5 can be connected to the left side beam 1, and the lower part of its right end can be connected to the right side beam 1, so as to fix the third airbag 5 to the frame and enable the third airbag 5 to seal the opening to be sealed when inflated. Preferably, the top of the third airbag 5 is connected to the top beam 2, and the left and right ends of the third airbag 5 are respectively connected to the side beam 1 on the corresponding side.

[0046] The third airbag 5 can be directly connected to the top beam 2 and the side beam 1. For example, the top beam 2 and the side beam 1 each have protrusions. The protrusion of the top beam 2 passes through the second airbag 4 and connects to the third airbag 5, and the protrusion of the side beam 1 passes through the first airbag 3 and connects to the third airbag 5. The third airbag 5 can also be indirectly connected to the top beam 2 and the side beam 1 via connecting components. For example, the top beam 2 and the side beam 1 each have connecting components, such as connecting ropes or connecting bolts. The connecting component of the top beam 2 passes through the second airbag 4 and connects to the third airbag 5, and the connecting component of the side beam 1 passes through the first airbag 3 and connects to the third airbag 5. The third airbag 5 can also be indirectly connected to the side beam 1 by connecting to the first airbag 3, and indirectly connected to the top beam 2 by connecting to the second airbag 4.

[0047] The adaptive high-strength roadway sealing device of this invention is provided with side beams and top beams to form an opening to be sealed, and the opening to be sealed is sealed by a third airbag. At the same time, a first airbag is fitted around the outer periphery of the side beam to seal the gap between the side beam and the roadway sidewall, and a second airbag is fitted around the outer periphery of the top beam to seal the gap between the top beam and the roadway roof, so that the adaptive high-strength roadway sealing device of this invention can completely seal the roadway.

[0048] In some embodiments, the third airbag 5 is movable between a folded position and a blocking position. In the folded position, the top of the third airbag 5 is connected to the top of the top beam 2 and / or the top of at least two side beams 1, the side beams 1 having a midpoint in the vertical direction, and the bottom of the third airbag 5 is connected to the at least two side beams 1 and located on the side of the midpoint facing the top beam 2. In the blocking position, the top of the third airbag 5 is connected to the top of the top beam 2 and / or the top of at least two side beams 1, and the bottom of the third airbag 5 is connected to the bottom of the at least two side beams 1.

[0049] Specifically, the side beam 1 has a midpoint in the vertical direction, and the third airbag 5 can move between a folded position and a blocked position. In the folded position, the top of the third airbag 5 is connected to the top beam 2, the left end of the bottom of the third airbag 5 is connected above the midpoint of the left side beam 1, and the right end of the bottom of the third airbag 5 is connected above the midpoint of the right side beam 1. At this time, the third airbag 5 is not inflated, and the third airbag 5 is in a folded, stacked, or rolled-up state in the vertical direction.

[0050] At the sealing position, the top of the third airbag 5 is connected to the top beam 2, the left end of the bottom of the third airbag 5 is connected to the bottom of the left side beam 1, and the right end of the bottom of the third airbag 5 is connected to the bottom of the right side beam 1. In the projection plane perpendicular to the paper, the projection of the third airbag 5 coincides with the projection of the opening to be sealed, and the projection area of ​​the third airbag 5 is greater than or equal to the projection area of ​​the opening to be sealed. The opening to be sealed is completely blocked by the third airbag 5. At this time, the third airbag 5 can be inflated or not inflated, and the third airbag 5 is in an deployed state in the vertical direction. When sealing the opening to be sealed, the third airbag 5 is in an inflated state.

[0051] In other words, during the movement of the third airbag 5 between the folded position and the blocking position, the top of the third airbag 5 is always connected to the top beam 2, and the bottom of the third airbag 5 moves vertically relative to the corresponding side beam 1. The third airbag 5 can move by folding, stacking, or rolling up.

[0052] When the third airbag 5 is indirectly connected to the side beam 1 by connecting the first airbag 3, the first airbag 3 moves up and down synchronously with the bottom of the third airbag 5. In other words, when the bottom of the third airbag 5 moves up and down, the first airbag 3 moves up and down synchronously on the corresponding side beam 1. When the third airbag 5 is in the folded position, the first airbag 3 is in a stacked state.

[0053] When the third airbag is in the blocking position, the opening to be blocked is blocked, and personnel and equipment cannot pass through. When the third airbag is in the folded position, the lower part of the opening to be blocked is released, and personnel and equipment can pass through.

[0054] It is understood that the third airbag is not limited to having a folded position and a blocking position. In other embodiments, the third airbag only has a blocking position. When personnel and equipment need to pass through the opening to be blocked, the third airbag needs to be disassembled, or personnel and equipment cannot pass through the opening to be blocked.

[0055] In some embodiments, the top of the side beam 1 is hinged to the top beam 2 so that the side beam 1 can rotate relative to the top beam 2 about a second direction (the direction perpendicular to the plane of the paper), the second direction being orthogonal to the vertical direction and the first direction.

[0056] In some embodiments, the angle between the centerline of the side beam 1 and the centerline of the top beam 2 is 90° to 135°.

[0057] like Figure 1 As shown, the left end of the top beam 2 is hinged to the top of the left side beam 1, so that the left side beam 1 can rotate clockwise and counterclockwise relative to the top beam 2. Preferably, the angle between the centerline of the left side beam 1 and the centerline of the top beam 2 is 90° to 135°. In other words, the left side beam 1 can extend vertically in the up-down direction, or it can extend from top to bottom and tilt to the left.

[0058] The right end of the top beam 2 is hinged to the top of the right side beam 1, so that the right side beam 1 can rotate clockwise and counterclockwise relative to the top beam 2. Preferably, the angle between the centerline of the right side beam 1 and the centerline of the top beam 2 is 90° to 135°. In other words, the right side beam 1 can extend vertically in the up-down direction, or it can extend from top to bottom and tilt to the right.

[0059] So that the frame formed by the top beam 2 and the side beam 1 can have a rectangular state and a trapezoidal state, so as to adapt to the roadway sidewalls with different shapes and different inclination angles.

[0060] The top beam 2 has a first protrusion and a second protrusion, and the side beam 1 can rotate between a first position and a second position. In the first position, one side of the side beam 1 abuts against the first protrusion, and in the second position, the other side of the side beam 1 abuts against the second protrusion.

[0061] Specifically, the top beam 2 includes a beam body and a connecting shaft. The side beam 1 is connected to the connecting shaft so that the side beam 1 and the top beam 2 are hinged. The connecting shaft can be fixedly connected to the beam body or rotatably connected to the beam body. When the connecting shaft is fixedly connected to the beam body, the connecting shaft or the beam body is provided with a first protrusion and a second protrusion. The first and second protrusions are used to abut against the side beam 1. When the included angle between the side beam 1 and the top beam 2 is 90°, the first protrusion abuts against the side beam 1. When the included angle between the side beam 1 and the top beam 2 is 135°, the second protrusion abuts against the side beam 1, thereby limiting the included angle range between the side beam 1 and the top beam 2 through the first and second protrusions. When the connecting shaft is rotatably connected to the beam body, the beam body is provided with the first and second protrusions.

[0062] In some embodiments, the adaptive high-strength tunnel sealing device of the present invention further includes a mounting member 6, a first telescopic member 7, and a second telescopic member 8. The mounting member 6 is located within the opening to be sealed, and its top end is connected to a top beam 2. The mounting member 6 and the third airbag 5 are arranged at intervals in a second direction. The first telescopic member 7 is mounted on the mounting member 6 and connected to a side beam 1 located at the outermost end in the first direction to drive the side beam 1 to rotate around the second direction. The second telescopic member 8 is mounted on the mounting member 6 and connected to another side beam 1 located at the outermost end in the first direction to drive the other side beam 1 to rotate around the second direction.

[0063] like Figure 1 As shown, the mounting member 6 is preferably a mounting rod. The mounting member 6 is located inside the opening to be sealed, and the mounting member 6 and the third airbag 5 are spaced apart in the direction perpendicular to the paper. The top of the mounting member 6 is connected to the top beam 2, and the bottom of the mounting member 6 is provided with a first telescopic member 7 and a second telescopic member 8. The first telescopic member 7 and the second telescopic member 8 are also spaced apart from the third airbag 5 in the direction perpendicular to the paper. The first telescopic member 7 extends to the left from the mounting member 6, and the left end of the first telescopic member 7 is connected to the left-side side beam 1, so that the left-side side beam 1 can be driven to rotate by the telescopic movement of the first telescopic member 7 in the left-right direction. The second telescopic member 8 extends to the right from the mounting member 6, and the right end of the second telescopic member 8 is connected to the right-side side beam 1, so that the right-side side beam 1 can be driven to rotate by the telescopic movement of the second telescopic member 8 in the left-right direction.

[0064] The first telescopic member 7 and the second telescopic member 8 can be connected to the corresponding side beam 1 by abutment, or they can be connected to the corresponding side beam 1 by a slide rail extending in the vertical direction, so that when the first telescopic member 7 and the second telescopic member 8 are extended or retracted, the end of the first telescopic member 7 and the second telescopic member 8 used to connect to the side beam 1 can move relative to the corresponding side beam in the vertical direction. The first telescopic member 7 and the second telescopic member 8 are preferably hydraulic telescopic rods.

[0065] The second airbag 4 has a through hole for the mounting member 6 to pass through, and the first airbag 3 has a strip-shaped through hole for the corresponding first telescopic member 7 or second telescopic member 8 to pass through, the strip-shaped through hole extending in the vertical direction.

[0066] Preferably, the first telescopic member 7 and the second telescopic member 8 are located above the midpoint of the side beam 1.

[0067] It is understandable that the structure of the adaptive high-strength roadway sealing device is not limited to, for example... Figure 1 In some embodiments of the structure shown, the top beam and side beams are fixedly connected, in which case there is no need to provide mounting parts, a first telescopic member and a second telescopic member, and the top beam does not need to have a first protrusion and a second protrusion.

[0068] In some embodiments, the adaptive high-strength roadway sealing device of the present invention further includes a third telescopic member 9. The side beam 1 located at the outermost end in the first direction is provided with the third telescopic member 9. One end of the third telescopic member 9 is located on the side of the side beam 1 away from the opening to be sealed, and one end of the third telescopic member 9 can telescopically move relative to the side beam 1 in the first direction.

[0069] like Figure 1 As shown, a third telescopic member 9 is provided on the left side beam 1. The left end of the third telescopic member 9 is located on the left side of the left side beam 1. The third telescopic member 9 can extend and retract in the left and right directions so that the left end of the third telescopic member 9 can extend to the left to abut against the side wall of the tunnel and then automatically retract. Another third telescopic member 9 is provided on the right side beam 1. The right end of the third telescopic member 9 is located on the right side of the right side beam 1. The third telescopic member 9 can extend and retract in the left and right directions so that the right end of the third telescopic member 9 can extend to the right to abut against the side wall of the tunnel and then automatically retract.

[0070] The third telescopic component 9 includes a telescopic component body 91, an explosion-proof power supply 92, and a support 93. The explosion-proof power supply 92 is located on the inner side of the side beam 1. In other words, there is an explosion-proof power supply 92 on the right side of the left side beam 1 and an explosion-proof power supply 92 on the left side of the right side beam 1. The first airbag 3 has a through hole for accommodating the explosion-proof power supply 92.

[0071] The telescopic body 91 is preferably a hydraulic cylinder. The telescopic body 91 is electrically connected to a corresponding explosion-proof power supply 92 so as to telescopically move under the drive of the explosion-proof power supply 92. The outer end of the telescopic body 91 telescopically moves outward from the corresponding side beam 1 by a distance of 0m to 0.3m. Therefore, most of the telescopic body 91 is located inside the side beam 1, and most of the telescopic body 91 is arranged at intervals with the third airbag 5 in a direction perpendicular to the paper plane. The first airbag 3 is provided with a through hole for the telescopic body 91 to pass through.

[0072] A support 93 is located at the outer end of the telescopic component body 91. The support 93 is disc-shaped, having a larger end face area than the outer end of the telescopic component body 91, to abut against the tunnel sidewall and increase friction with it. Preferably, the end face area of ​​the support 93 is 0.2 m². 2 up to 0.4m 2 .

[0073] The outer end of the third expansion joint abuts against the sidewall of the roadway to fix the frame formed by the top beam and side beam, preventing the adaptive high-strength roadway sealing device from shifting or tipping over when subjected to external forces. When the adaptive high-strength roadway sealing device has a third expansion joint, the first and second expansion joints also serve to support the side beams, preventing the side beams from rotating inward under the pressure of the third expansion joint.

[0074] It is understood that the adaptive high-strength roadway sealing device is not limited to having a third telescopic member. In some other embodiments, the adaptive high-strength roadway sealing device does not have a third telescopic member, and the friction between the first airbag and the roadway sidewall, and the friction between the second airbag and the roadway roof, play a fixing role.

[0075] In some embodiments, the adaptive high-strength roadway sealing device of the present invention further includes a movable frame 10 and a connector. The movable frame 10 includes a frame body 101 and movable wheels 102. The movable wheels 102 are located at the bottom of the frame body 101. The frame body 101 is detachably connected to the side beam 1 through the connector. The first airbag 3 has a through hole for the connector to pass through.

[0076] like Figure 1 and Figure 2 As shown, the mobile frame 10 includes a frame body 101 and casters 102. The frame body 101 is preferably triangular. The top of the frame body 101 is detachably connected to the side beam 1 via a connector. The first airbag 3 has a through hole for the connector to pass through, and the first airbag 3 is located between the frame body 101 and the side beam 1. The bottom of the frame body 101 is provided with casters 102. Preferably, the connector is a bolt, and the casters 102 are casters. This facilitates the movement of the frame formed by the top beam and the side beam, and facilitates the rotation of the side beam within the tunnel.

[0077] It is understood that the adaptive high-strength roadway sealing device is not limited to having a movable frame and connectors; in other embodiments, the adaptive high-strength roadway sealing device does not have a movable frame and connectors.

[0078] In some embodiments, the dimensions of the top beam 2 in the first direction can be increased or decreased. The dimensions of the side beam 1 in the vertical direction can be increased or decreased.

[0079] The top beam 2 and side beam 1 can be telescopic beams, allowing their lengths to be increased or decreased by extending or contracting them. The top beam 2 and side beam 1 can also have multiple sub-beams, with adjacent sub-beams connected by bolts. The number of sub-beams connected allows for adjustments to the lengths of the top beam 2 and side beam 1.

[0080] like Figures 1-2 As shown, the tunnel sealing method of this invention includes...

[0081] The adaptive high-strength roadway sealing device is moved to the location in the roadway to be sealed. Specifically, the top beam 2 and the side beam 1 are in a retracted state, and the side beam 1 is equipped with a movable frame 10. By pushing the adaptive high-strength roadway sealing device, the adaptive high-strength roadway sealing device is moved to the location in the roadway to be sealed, while the roadway cross-section at the location to be sealed is quickly adjusted.

[0082] Adjust the dimensions of the top beam 2 in the first direction and the dimensions of the side beam 1 in the vertical direction. Specifically, adjust the lengths of the top beam 2 and the side beam 1 according to the cross-sectional height and width of the roadway, extending the top beam 2 and the side beam 1 from their contracted state.

[0083] The first telescopic member 7 and the second telescopic member 8 are activated to bring the outermost side beam 1 in the first direction closer to the corresponding tunnel sidewall. Specifically, the first telescopic member 7 and the second telescopic member 8 are activated. The first telescopic member 7 drives the left side beam 1 to rotate clockwise so that the left side beam 1 moves closer to the left tunnel sidewall until the centerline of the left side beam 1 is parallel to the extension direction of the projection of the left tunnel sidewall onto the tunnel cross-section. The second telescopic member 8 drives the right side beam 1 to rotate counterclockwise so that the right side beam 1 moves closer to the right tunnel sidewall until the centerline of the right side beam 1 is parallel to the extension direction of the projection of the right tunnel sidewall onto the tunnel cross-section.

[0084] The movable frame 10 is disassembled to detach from the side beam 1, and the bottom of the side beam 1 is positioned on the bottom surface of the roadway. Specifically, the connecting piece is removed from the side beam 1, allowing the movable frame 10 to detach from the corresponding side beam 1. The side beam 1 and the top beam 2 fall due to gravity, so that the bottom of the side beam 1 is positioned on the bottom surface of the roadway. This prevents the side beam 1 and the top beam 2 from shifting due to the movable wheel 102 during the sealing process. At this time, the vertical distance between the side beam 1 and the corresponding roadway sidewall is less than 10cm, and the vertical distance between the top beam 2 and the roadway roof is less than 15cm.

[0085] The third telescopic member 9 is activated so that it abuts against the corresponding tunnel sidewall. Specifically, the explosion-proof power supply 92 is turned on to activate the telescopic member body 91 and drive the support 93 to move outward until the support 93 abuts against the corresponding tunnel sidewall. The support 93 on the left side beam 1 abuts against the left tunnel sidewall, and the support 93 on the right side beam 1 abuts against the right tunnel sidewall. This secures the frame formed by the side beam 1 and the top beam 2 through the third telescopic member 9, preventing the frame from shifting and tipping over during the sealing process due to external forces. Preferably, the hydraulic pressure in the telescopic member body 91 is greater than or equal to 5 MPa.

[0086] Preferably, the installation time from the start of adjusting the top beam 2 and side beam 1 until the third expansion joint 9 abuts against the corresponding roadway sidewall is less than 8 minutes.

[0087] The first airbag 3 is inflated to abut against the roadway sidewall, the second airbag 4 is inflated to abut against the roadway roof, and the third airbag 5 is inflated to seal the opening to be sealed. Specifically, the third airbag 5 is moved from its folded position to its sealing position. The first airbag 3, the second airbag 4, and the third airbag 5 have medium inlets and outlets, each equipped with a quick-connect valve. These quick-connect valves are connected to the underground compressed air pipeline via a high-pressure hose to inflate the first airbag 3, the second airbag 4, and the third airbag 5, ensuring that the first airbag 3 abuts against the roadway sidewall, the second airbag 4 abuts against the roadway roof, and the third airbag 5 seals the opening to be sealed. The inflation pressure of the first airbag 3, the second airbag 4, and the third airbag 5 is 0.5 MPa to 2 MPa, and the inflation time is less than 2 minutes. After inflation, the high-pressure hose is disconnected from the quick-connect valve. At this point, the adaptive high-strength roadway sealing device has completed the sealing of the roadway.

[0088] During the sealing process of the adaptive high-strength roadway sealing device, the explosion-proof power supply 92 is in a dormant state. When the pressure inside the telescopic component body 91 is less than 5MPa, the explosion-proof power supply 92 automatically starts to raise the pressure inside the telescopic component body 91 to greater than or equal to 5MPa.

[0089] When the roadway needs to be unblocked, the recovery process of the adaptive high-strength roadway sealing device includes releasing the gas from the first airbag 3, the second airbag 4, and the third airbag 5. The third airbag 5 is moved from the blocking position to the folded position. The third telescopic member 9 retracts to detach from the corresponding roadway sidewall. The moving frame 10 is connected to the corresponding side beam 1. The first telescopic member 7 and the second telescopic member 8 retract so that the angle between the side beam 1 and the top beam 2 changes to 90°. The dimension of the top beam 2 in the first direction and the dimension of the side beam 1 in the vertical direction are shortened. The adaptive high-strength roadway sealing device is then withdrawn from the roadway.
