Description

Technical Field

[0001] The invention relates to the technical field of channel grouting equipment, and in particular to a visual channel plugging device for prestressed channel grouting and a plugging method thereof. Background Art

[0002] Grouting in prestressed channels usually refers to using pure cement slurry with external additives. Before grouting, the channel to be grouted is first rinsed with pressurized water, and then the pure cement slurry is pressed into one end of the hole, and the concentrated slurry is discharged from the other end and then sealed; the pressure is increased to 0.5-0.7 MPa and continued for 2-5 minutes before ending. Before grouting, the bridge prestressing should be tensioned. After the bridge prestressing is completed, the channel grouting should be carried out within 48 hours. The channel grouting adopts vacuum grouting. Before grouting, the vacuum pressure of -0.06 to -0.08MPa is maintained for 1 minute, and after grouting, the pressure of 0.5MPa to 0.6MPa is maintained for 3 minutes, and there is no leakage of water or slurry.

[0003] The publication number CN111456442A discloses a channel grouting auxiliary device and a grouting process. The device includes a slurry delivery pipe connected to a mud pump, a grouting pipe connected to the slurry delivery pipe, and an auxiliary sealing plate detachably arranged at the end of the grouting pipe, the auxiliary sealing plate is larger than the sealing hole, the auxiliary sealing plate is penetrated with a slurry outlet hole coaxial with the grouting pipe, the auxiliary sealing plate is also penetrated with a through hole adapted to the anchor rod extending out of the channel, an elastic extrusion layer is fixedly arranged on the surface of the auxiliary sealing plate, the device realizes that the auxiliary sealing plate will abut against the beam body on the peripheral side of the sealing hole after the anchor rod passes through the through hole, and the elastic extrusion layer on the plate surface is used for deformation, so that the auxiliary sealing plate is in close contact with the beam body, and finally the cement delivered through the grouting pipe can be quickly filled in the sealing hole; when the auxiliary sealing plate is subjected to the grouting, the auxiliary sealing plate is subjected to the grouting. During the grouting operation of the hole, the required grouting hole should be flushed with pressurized water before grouting to remove powder and other debris in the hole to ensure that the hole is unobstructed. After flushing, the accumulated water in the hole should be blown away, but the hole should be kept moist to make the cement slurry and the hole wall combine well. After the grouting hole is cleaned, it is necessary to seal the blocked hole with mud. The existing ones are to smooth the stirred mud and cover it on the blocked hole by personnel. After the cement is finally hardened and formed, the grouting operation can be carried out inside the grouting hole, thereby avoiding the leakage of mud through the blocked hole during the grouting operation, thereby affecting the product quality. Bridges generally belong to high-altitude operations and have relatively large safety hazards. However, there is currently no device that can clean the inside of the grouting hole in an integrated manner, and seal the blocked hole with mud after the cleaning is completed, thereby grouting the grouting hole.

[0011] Furthermore, the channel cleaning pipeline is provided with a docking hole.

[0012] A visual plugging method for a duct plugging device for prestressed duct grouting, the plugging method comprising the following steps:

[0013] S1: During the grouting operation of the channel, the required grouting channel should be rinsed with clean water before grouting. First, the mobile hydraulic cylinder is operated to drive the moving block on the driving end of the mobile hydraulic cylinder to move, and the movement of the moving block drives the moving plate to move in the slide groove, thereby driving the channel cleaning device on the moving plate to move in the direction of the grouting channel. After the channel cleaning device moves and passes through the channel blocking device, the moving rod on the moving device will abut against the channel blocking device, thereby also synchronously driving the channel blocking device to move in the direction of the grouting channel. When this device is operating, the position of the grouting channel or the blocking pipe is locked by the lifting device and the moving self-locking universal wheel which are always in a coordinated state, so that the grouting channel corresponds to the channel cleaning pipe, and then the head end of the channel cleaning pipe is inserted into the grouting channel through the operation of the moving device.

[0014] S2: After the head end of the channel cleaning pipe is inserted into the grouting channel, the channel cleaning hydraulic cylinder is operated to drive the channel cleaning piston on the driving end of the channel cleaning hydraulic cylinder to move up and down in the channel cleaning cylinder. When the channel cleaning piston moves from bottom to top in the channel cleaning cylinder, the control valves on the upper right water inlet pipe and the lower left water outlet pipe are in a closed state, while the control valves on the lower right water inlet pipe and the upper left water outlet pipe are in an open state, so that when the channel cleaning piston moves from bottom to top in the channel cleaning cylinder, the water inside the water tank enters the channel cleaning cylinder through the lower right water inlet pipe, and is discharged into the channel cleaning pipe through the upper left water outlet pipe. When the hole cleaning piston moves from top to bottom in the hole cleaning cylinder, the control valves on the upper right water inlet pipe and the lower left water outlet pipe are in an open state, while the control valves on the lower right water inlet pipe and the upper left water outlet pipe are in a closed state. As a result, when the hole cleaning piston moves from top to bottom in the hole cleaning cylinder, the water inside the water tank enters the hole cleaning cylinder through the upper right water inlet pipe, and is discharged into the hole cleaning pipe through the lower left water outlet pipe. The hole cleaning piston repeatedly moves up and down, so that the water inside the water tank is continuously inserted into the grouting hole through the hole cleaning pipe, thereby realizing the cleaning operation of the inserted grouting hole.

[0015] S3: Since water may accumulate after cleaning the inserted grouting hole, and the hole must be kept moist so that the cement slurry can be well combined with the hole wall, it is necessary to suck out the water accumulated in the inserted grouting hole, and in the process of sucking out, the accumulated water can be in contact with the grouting hole more evenly, so that the cement slurry can be well combined with the hole wall, so as to facilitate the subsequent grouting operation. At this time, the head end of the hole cleaning pipe is tapered and moves on the moving device. After the head end of the hole cleaning pipe is inserted into the grouting hole, it can effectively fit the grouting hole, so that the hole cleaning pipe and the inserted grouting hole are in a sealed environment. At this time, the hole cleaning hydraulic cylinder is driven to drive the hole cleaning piston on the driving end of the hole cleaning hydraulic cylinder to move up and down in the hole cleaning cylinder. When the hole cleaning piston moves from bottom to top in the hole cleaning cylinder, the lower right water inlet pipe and the upper left water outlet pipe are The control valve on the water pipe is in a closed state, while the control valves on the upper right water inlet pipe and the lower left water outlet pipe are in an open state, so that when the channel cleaning piston moves from bottom to top in the channel cleaning cylinder, a suction force is formed on the inserted grouting channel. When the channel cleaning piston moves from top to bottom in the channel cleaning cylinder, the control valves on the upper right water inlet pipe and the lower left water outlet pipe are in a closed state, while the control valves on the lower right water inlet pipe and the upper left water outlet pipe are in an open state, and at this time a suction force is formed on the inserted grouting channel. The channel cleaning piston repeatedly moves up and down in the channel cleaning cylinder, thereby sucking out the accumulated water in the grouting channel through suction, and also makes the accumulated water flow and the contact with the grouting channel more uniform, realizing the discharge of the accumulated water in the inserted grouting channel, and also facilitating the subsequent good combination of cement slurry and hole wall, thereby improving the quality and efficiency of the product.

[0016] S4: After the cleaning of the inside of the grouting channel is completed, when the moving device drives the channel cleaning device to move in the direction of the blocked channel, one end of the two moving rods will slide a distance in the sliding grooves on both sides of the conversion seat. When the two moving rods slide and hit the ends of the sliding grooves on both sides of the conversion seat, the two moving rods will hit the conversion seat when they continue to move, thereby driving the conversion seat to move in the direction of the blocked channel, and driving the conversion device to move in the direction of the blocked channel, so that the channel blocking pipe and the blocking pipe are pressed together. After the moving channel blocking pipe and the blocking pipe are pressed together, the mud stirred inside the mixing equipment is discharged into the blocking pipe through the connecting pipe by driving the pump, and flows into the blocking pipe that has just been pressed together, thereby facilitating subsequent blocking operations of the blocked channel.

[0017] S5: When the inside of the grouting pipe is cleaned, the extrusion plate in the extrusion device can be supported by the hole cleaning pipe and pass through the hole blocking pipe through the operation of the conversion device. When the mud stirred inside the mixing equipment is discharged into the blocking pipe through the connecting pipe by driving the pump, and flows into the just pressed blocking pipe, the extrusion plate in the extrusion device is supported by the hole cleaning pipe through the operation of the conversion device. Through the action of the limit block, the extrusion piece can only be pushed to move in the hole blocking pipe toward the blocking pipe, thereby pushing the mud inside the hole blocking pipe into the blocking pipe, and limiting the extrusion piece to block the mud in the blocking pipe from flowing back into the hole blocking pipe, etc. After a period of time, when the moving device drives the channel cleaning device to move away from the blocked channel, one end of the two moving rods will slide a distance in the sliding grooves on both sides of the conversion seat. At this time, the channel cleaning pipeline and the conversion device are not in contact. At the same time, the operation of the conversion device drives the channel blocking device to change direction without contacting the channel cleaning device. When the two moving rods slide and hit the end of the other side of the sliding grooves on both sides of the conversion seat, the two moving rods will hit the conversion seat during continuous movement, thereby driving the conversion seat to move away from the blocked channel, thereby driving the channel blocking device on the conversion device to separate from the blocked channel, and the extrusion rod returns to its original position through the rebound force of the extrusion spring, thereby realizing the blocking operation of the blocked pipeline.

[0018] S6: After the cleaning of the grouting pipe and the plugging of the plugging pipe are completed, it is necessary to perform grouting operation on the inside of the grouting pipe. At this time, the operation of the conversion device drives the hole plugging device to rotate, so that the limit block is facing the hole cleaning pipe, so that the hole cleaning pipe lifts the extrusion plate through the hole plugging pipe through the operation of the moving device, and the docking hole on the hole cleaning pipe corresponds to the connecting pipe connected to the hole plugging pipe, and is in a matching state. At this time, the head end of the hole cleaning pipe is also converted and inserted into the grouting pipe, so that the mud stirred by the mixing equipment can be passed through the driving pump. The mud flows into the channel cleaning pipe through the connecting pipe, thereby pressing the mud into the grouting pipe through the channel cleaning pipe, thereby realizing the grouting operation in the grouting pipe; when the grouting operation is completed, the device is moved back to its original position, and there will be unsolidified mud inside the channel cleaning pipe and the channel sealing pipe, which is not convenient for the next grouting operation. At this time, the water inside the water tank is discharged through the operation of the channel cleaning piston, and the head end of the channel cleaning pipe is moved to the channel sealing pipe through the operation of the moving device, thereby realizing the cleaning operation of the channel cleaning pipe and the channel sealing pipe to facilitate the next grouting operation.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] Firstly, in the process of grouting the channel of the present invention, the required grouting channel should be rinsed with clean water before grouting. Firstly, the mobile hydraulic cylinder is operated to drive the moving block on the driving end of the mobile hydraulic cylinder to move, and the movement of the moving block drives the moving plate to move in the slide groove, thereby driving the channel cleaning device on the moving plate to move in the direction of the grouting channel. After the channel cleaning device moves and passes through the channel blocking device, the moving rod on the moving device will abut against the channel blocking device, thereby also synchronously driving the channel blocking device to move in the direction of the grouting channel. When the device is operating, the position of the grouting channel or the blocking pipeline is locked by the matching state of the lifting device and the moving self-locking universal wheel, so that the grouting channel corresponds to the channel cleaning pipeline, and then the head end of the channel cleaning pipeline is inserted into the grouting channel through the operation of the moving device;

[0021] When the head end of the channel cleaning pipe is inserted into the grouting channel, the channel cleaning hydraulic cylinder is operated to drive the channel cleaning piston on the driving end of the channel cleaning hydraulic cylinder to move up and down in the channel cleaning tube. When the channel cleaning piston moves from bottom to top in the channel cleaning tube, the control valves on the upper right water inlet pipe and the lower left water outlet pipe are in a closed state, while the control valves on the lower right water inlet pipe and the upper left water outlet pipe are in an open state, so that when the channel cleaning piston moves from bottom to top in the channel cleaning tube, the water inside the water tank enters the channel cleaning tube through the lower right water inlet pipe, and is discharged into the channel cleaning pipe through the upper left water outlet pipe. When the channel cleaning piston moves from top to bottom in the channel cleaning cylinder, the control valves on the upper right water inlet pipe and the lower left water outlet pipe are in an open state, while the control valves on the lower right water inlet pipe and the upper left water outlet pipe are in a closed state, so that the channel cleaning piston moves from top to bottom in the channel cleaning cylinder to allow the water inside the water tank to enter the channel cleaning cylinder through the upper right water inlet pipe, and is discharged into the channel cleaning pipe through the lower left water outlet pipe. The channel cleaning piston repeatedly moves up and down, so that the water inside the water tank is continuously inserted into the grouting channel through the channel cleaning pipe, thereby realizing the cleaning operation of the inserted grouting channel;

[0022] Since water may accumulate in the inserted grouting hole after cleaning, and the hole must be kept moist so that the cement slurry can be well combined with the hole wall, it is necessary to suck out the water accumulated in the inserted grouting hole, and in the process of sucking out, the accumulated water can be made to contact the grouting hole more evenly, so that the cement slurry can be well combined with the hole wall, so as to facilitate subsequent grouting operations. At this time, the head end of the hole cleaning pipe is tapered and moves on the moving device. After the head end of the hole cleaning pipe is inserted into the grouting hole, it can effectively fit the grouting hole, so that the hole cleaning pipe and the inserted grouting hole are in a sealed environment. At this time, the hole cleaning hydraulic cylinder is driven to drive the hole cleaning piston on the driving end of the hole cleaning hydraulic cylinder to move up and down in the hole cleaning cylinder. When the hole cleaning piston moves from bottom to top in the hole cleaning cylinder, the lower right water inlet pipe and the upper left water outlet pipe The control valve on the channel is in a closed state, while the control valves on the upper right water inlet pipe and the lower left water outlet pipe are in an open state, so that when the channel cleaning piston moves from bottom to top in the channel cleaning cylinder, a suction force is formed on the inserted grouting channel. When the channel cleaning piston moves from top to bottom in the channel cleaning cylinder, the control valves on the upper right water inlet pipe and the lower left water outlet pipe are in a closed state, while the control valves on the lower right water inlet pipe and the upper left water outlet pipe are in an open state, and at this time a suction force is formed on the inserted grouting channel, and the channel cleaning piston repeatedly moves up and down in the channel cleaning cylinder, so that the accumulated water in the grouting channel is sucked out by suction, and the flow of the accumulated water is made to contact the grouting channel more evenly, thereby realizing the discharge of the accumulated water in the inserted grouting channel, and facilitating the subsequent good combination of cement slurry and hole wall, thereby improving the quality and efficiency of the product.

[0023] Secondly, after the cleaning of the inside of the grouting channel is completed, when the moving device drives the channel cleaning device to move in the direction of the blocked channel, one end of the two moving rods will slide a distance in the sliding grooves on both sides of the conversion seat. When the two moving rods slide and hit the ends of the sliding grooves on both sides of the conversion seat, the two moving rods will hit the conversion seat during continuous movement, thereby driving the conversion seat to move in the direction of the blocked channel, thereby driving the conversion device to move in the direction of the blocked channel, thereby driving the channel blocking pipe and the blocking pipe to be pressed together. After the pressing of the moving channel blocking pipe and the blocking pipe is completed, the mud stirred inside the stirring equipment is discharged into the blocking pipe through the connecting pipe by driving the pump, and flows into the blocking pipe that has just been pressed together, thereby facilitating subsequent blocking operations of the blocked channel.

[0024] Thirdly, when the present invention is cleaning the inside of the grouting pipe, the extrusion plate in the extrusion device can be supported by the channel cleaning pipe and pass through the channel blocking pipe through the operation of the conversion device. When the mud stirred inside the stirring equipment is discharged into the blocking pipe through the connecting pipe by driving the pump, and flows into the just pressed blocking pipe, the extrusion plate in the extrusion device is supported by the channel cleaning pipe through the operation of the conversion device. Through the action of the limit block, the extrusion piece can only be pushed to move in the channel blocking pipe in the direction of the blocking pipe, thereby pushing the mud inside the channel blocking pipe into the blocking pipe, and the extrusion piece is limited to block the mud in the blocking pipe from flowing back into the channel blocking pipe. After waiting for a while, when the moving device drives the channel cleaning device to move away from the blocked channel, one end of the two moving rods will slide a distance in the sliding grooves on both sides of the conversion seat. At this time, the channel cleaning pipeline and the conversion device are not in contact. At the same time, the operation of the conversion device drives the channel blocking device to change direction without contacting the channel cleaning device. When the two moving rods slide and hit the end of the other side of the sliding grooves on both sides of the conversion seat, the two moving rods will hit the conversion seat during continuous movement, thereby driving the conversion seat to move away from the blocked channel, thereby driving the channel blocking device on the conversion device to separate from the blocked channel, and the extrusion rod returns to its original position through the rebound force of the extrusion spring, thereby realizing the blocking operation of the blocked pipeline.

[0025] Fourthly, in the present invention, after the cleaning of the grouting pipe and the sealing of the plugging pipe are completed, it is necessary to perform grouting operation on the inside of the grouting pipe. At this time, the operation of the conversion device drives the hole plugging device to rotate, so that the limit block is directed toward the hole cleaning pipe, so that the hole cleaning pipe lifts the extrusion plate through the hole plugging pipe through the operation of the moving device, and the docking hole on the hole cleaning pipe just corresponds to the connecting pipe connected to the hole plugging pipe, and is in a matching state. At this time, the head end of the hole cleaning pipe is also converted and inserted into the grouting pipe, so that the mud stirred by the stirring equipment can be driven by the operation of the pump. The mud flows into the channel cleaning pipe through the connecting pipe, thereby pressing the mud into the grouting pipe through the channel cleaning pipe, thereby realizing the grouting operation in the grouting pipe; when the grouting operation is completed, the device is moved back to its original position, and there will be unsolidified mud inside the channel cleaning pipe and the channel sealing pipe, which is not convenient for the next grouting operation. At this time, the water inside the water tank is discharged through the operation of the channel cleaning piston, and the head end of the channel cleaning pipe is moved to the channel sealing pipe through the operation of the moving device, thereby realizing the cleaning operation of the channel cleaning pipe and the channel sealing pipe to facilitate the next grouting operation.

When the two moving rods 24 slide and hit the ends of the sliding grooves 42 on both sides of the conversion seat 41, the two moving rods 24 will hit the conversion seat 41 as they continue to move, thereby driving the conversion seat 41 to move in the direction of the blocked channel, thereby driving the conversion device 4 to move in the direction of the blocked channel, thereby driving the channel blocking pipe 53 to be pressed together with the blocking pipe. After the moving channel blocking pipe 53 is pressed together with the blocking pipe, the mud stirred inside the stirring device 51 is discharged into the blocking pipe through the connecting pipe 55 by driving the pump 52, and flows into the blocking pipe that has just been pressed together, thereby facilitating subsequent blocking operations of the blocked channel.

After waiting for a period of time, when the moving device 2 drives the channel cleaning device 3 to move away from the blocked channel, one end of the two moving rods 24 will slide a distance in the sliding grooves 42 on both sides of the conversion seat 41. At this time, the channel cleaning pipe The channel 37 and the conversion device 4 do not contact each other, and the conversion device 4 drives the channel plugging device 5 to change direction when it is running, and will not contact the channel cleaning device 3.

[0055] A visual plugging method for a duct plugging device for prestressed duct grouting, the plugging method comprising the following steps:

[0056] S1: During the grouting operation of the channel, the required grouting channel should be rinsed with clean water before grouting. First, the mobile hydraulic cylinder 22 is operated to drive the moving block 23 on the driving end of the mobile hydraulic cylinder 22 to move. The movement of the moving block 23 drives the moving plate 25 to move in the slide groove 13, thereby driving the channel cleaning device 3 on the moving plate 25 to move in the direction of the grouting channel. After the channel cleaning device 3 moves and passes through the channel blocking device 5, the moving rod 24 on the moving device 2 will abut against the channel blocking device 5, thereby also synchronously driving the channel blocking device 5 to move in the direction of the grouting channel. When this device is operating, the position of the grouting channel or the blocking pipe is locked by the matching state of the lifting device 1 and the moving self-locking universal wheel 11, so that the grouting channel corresponds to the channel cleaning pipe 37, and then the head end of the channel cleaning pipe 37 is inserted into the grouting channel through the operation of the moving device 2.

[0057] S2: After the head end of the channel cleaning pipe 37 is inserted into the grouting channel, the channel cleaning hydraulic cylinder 34 is operated to drive the channel cleaning piston 35 on the driving end of the channel cleaning hydraulic cylinder 34 to move up and down in the channel cleaning tube 32. When the channel cleaning piston 35 moves from bottom to top in the channel cleaning tube 32, the control valves on the upper right water inlet pipe 39 and the lower left water outlet pipe 393 are in a closed state, while the control valves on the lower right water inlet pipe 391 and the upper left water outlet pipe 392 are in an open state, so that when the channel cleaning piston 35 moves from bottom to top in the channel cleaning tube 32, the water inside the water tank 31 enters the channel cleaning tube 32 through the lower right water inlet pipe 391, and is discharged into the channel cleaning pipe through the upper left water outlet pipe 392. In the channel 37, when the channel cleaning piston 35 moves from top to bottom in the channel cleaning cylinder 32, the control valves on the upper right water inlet pipe 39 and the lower left water outlet pipe 393 are in an open state, while the control valves on the lower right water inlet pipe 391 and the upper left water outlet pipe 392 are in a closed state, so that when the channel cleaning piston 35 moves from top to bottom in the channel cleaning cylinder 32, the water inside the water tank 31 enters the channel cleaning cylinder 32 through the upper right water inlet pipe 39, and is discharged into the channel cleaning pipe 37 through the lower left water outlet pipe 393. The channel cleaning piston 35 repeatedly moves up and down, so that the water inside the water tank 31 is continuously inserted into the grouting channel through the channel cleaning pipe 37, thereby realizing the cleaning operation of the inserted grouting channel.

[0058] S3: Since water may accumulate in the inserted grouting channel after cleaning, and the channel must be kept moist so that the cement slurry can be well combined with the hole wall, it is necessary to suck out the water accumulated in the inserted grouting channel, and in the process of sucking out, the accumulated water can be in contact with the grouting channel more evenly, so that the cement slurry can be well combined with the hole wall, so as to facilitate subsequent grouting operations. At this time, the head end of the channel cleaning pipe 37 is tapered and moves on the moving device 2. After the head end of the channel cleaning pipe 37 is inserted into the grouting channel, it can effectively fit the grouting channel, so that the channel cleaning pipe 37 and the inserted grouting channel are in a sealed environment. At this time, the channel cleaning hydraulic cylinder 34 is driven to drive the channel cleaning piston 35 on the driving end of the channel cleaning hydraulic cylinder 34 to move up and down in the channel cleaning tube 32. When the channel cleaning piston 35 moves from bottom to top in the channel cleaning tube 32, the lower right water inlet pipe 391 and the upper left water outlet pipe 39 2 is in a closed state, while the control valves on the upper right water inlet pipe 39 and the lower left water outlet pipe 393 are in an open state, so that when the channel cleaning piston 35 moves from bottom to top in the channel cleaning cylinder 32, a suction force is formed on the inserted grouting channel. When the channel cleaning piston 35 moves from top to bottom in the channel cleaning cylinder 32, the control valves on the upper right water inlet pipe 39 and the lower left water outlet pipe 393 are in a closed state, while the control valves on the lower right water inlet pipe 391 and the upper left water outlet pipe 392 are in an open state. At this time, a suction force is formed on the inserted grouting channel. The channel cleaning piston 35 repeatedly moves up and down in the channel cleaning cylinder 32, so that the accumulated water in the grouting channel is sucked out by suction, and the accumulated water flow is made to contact the grouting channel more evenly, thereby realizing the discharge of the accumulated water in the inserted grouting channel, and facilitating the subsequent good combination of cement slurry and hole wall, thereby improving the quality and efficiency of the product.

[0059] S4: After the cleaning of the inside of the grouting channel is completed, when the moving device 2 drives the channel cleaning device 3 to move in the direction of the blocked channel, one end of the two moving rods 24 will slide a distance in the sliding grooves 42 on both sides of the conversion seat 41. When the two moving rods 24 slide and hit the ends of the sliding grooves 42 on both sides of the conversion seat 41, the two moving rods 24 will hit the conversion seat 41 as they continue to move, thereby driving the conversion seat 41 to move in the direction of the blocked channel, thereby driving the conversion device 4 to move in the direction of the blocked channel, thereby driving the channel blocking pipe 53 to be pressed together with the blocking pipe. After the moving channel blocking pipe 53 is pressed together with the blocking pipe, the mud stirred inside the stirring device 51 is discharged into the blocking pipe through the connecting pipe 55 by driving the pump 52, and flows into the blocking pipe that has just been pressed together, thereby facilitating subsequent blocking operations of the blocked channel.

[0060] S5: When the inside of the grouting pipe is cleaned, the extrusion plate 64 in the extrusion device 6 can be supported by the channel cleaning pipe 37 through the operation of the conversion device 4, and pass through the channel blocking pipe 53. When the mud stirred inside the stirring device 51 is discharged into the blocking pipe through the connecting pipe 55 by the driving pump 52, and flows into the just pressed blocking pipe, the extrusion plate 64 in the extrusion device 6 is supported by the channel cleaning pipe 37 through the operation of the conversion device 4. Through the action of the limit block 65, the extrusion piece 66 can only be pushed to move in the channel blocking pipe direction in the channel blocking pipe 53, thereby pushing the mud inside the channel blocking pipe 53 into the blocking pipe, and the extrusion piece 66 is limited to block the mud in the blocking pipe from flowing back into the channel blocking pipe 53, etc. After a period of time, when the moving device 2 drives the channel cleaning device 3 to move away from the blocked channel, one end of the two moving rods 24 will slide a distance in the sliding grooves 42 on both sides of the conversion seat 41. At this time, the channel cleaning pipe 37 and the conversion device 4 are not in contact. At the same time, the operation of the conversion device 4 drives the channel blocking device 5 to change direction without contacting the channel cleaning device 3. When the two moving rods 24 slide and contact the ends on the other side of the sliding grooves 42 on both sides of the conversion seat 41, the two moving rods 24 will contact the conversion seat 41 as they continue to move, thereby driving the conversion seat 41 to move away from the blocked channel, thereby driving the channel blocking device 5 on the conversion device 4 to disengage from the blocked channel, and the extrusion rod 62 returns to its original position through the rebound force of the extrusion spring 63, thereby realizing the blocking operation of the blocked pipe.

[0061] S6: After the cleaning of the grouting pipe and the plugging of the plugging pipe are completed, it is necessary to perform grouting operation on the inside of the grouting pipe. At this time, the operation of the conversion device 4 drives the channel plugging device 5 to rotate, so that the limit block 65 is directed toward the channel cleaning pipe 37, so that the channel cleaning pipe 37 is lifted by the operation of the moving device 2 to pass through the channel plugging pipe 53, and the docking hole 38 on the channel cleaning pipe 37 corresponds to the connecting pipe 55 connected to the channel plugging pipe 53, and is in a matching state. At this time, the head end of the channel cleaning pipe 37 is also converted and inserted into the grouting pipe, so that the mud mixed by the mixing equipment 51 can be moved by driving the pump 52. The slurry flows into the channel cleaning pipe 37 through the connecting pipe 55, thereby pressing the mud into the grouting pipe through the channel cleaning pipe 37, thereby realizing the grouting operation in the grouting pipe; when the grouting operation is completed, the device is moved back to its original position, and there will be unsolidified mud inside the channel cleaning pipe 37 and the channel blocking pipe 53, which is not convenient for the next grouting operation. At this time, the water inside the water tank 31 is discharged through the operation of the channel cleaning piston 35, and the head end of the channel cleaning pipe 37 is moved to the channel blocking pipe 53 through the operation of the moving device 2, thereby realizing the cleaning operation of the channel cleaning pipe 37 and the channel blocking pipe 53, so as to facilitate the next grouting operation.

4. A method for visualizing a prestressed channel grouting duct plugging device according to any one of claims 1 to 3, the plugging method comprising the following steps: S1: During the grouting operation of the channel, the required grouting channel should be rinsed with clean water before grouting. First, the mobile hydraulic cylinder (22) is operated to drive the moving block (23) on the driving end of the mobile hydraulic cylinder (22) to move. The movement of the moving block (23) drives the moving plate (25) to move in the slide groove (13), thereby driving the channel cleaning device (3) on the moving plate (25) to move in the direction of the grouting channel. After the channel cleaning device (3) moves and passes through the channel blocking device (5), the moving device ( 2) will contact the channel plugging device (5), thereby synchronously driving the channel plugging device (5) to move in the direction of the grouting channel. When the device is in operation, the lifting device (1) and the movable self-locking universal wheel (11) are always in a coordinated state to lock the position of the grouting channel or the plugging pipeline, so that the grouting channel corresponds to the channel cleaning pipeline (37), and then the head end of the channel cleaning pipeline (37) is inserted into the grouting channel through the operation of the moving device (2); S2: After the head end of the hole cleaning pipe (37) is inserted into the grouting hole, the hole cleaning hydraulic cylinder (34) is operated to drive the hole cleaning piston (35) on the driving end of the hole cleaning hydraulic cylinder (34) to move up and down in the hole cleaning cylinder (32). When the hole cleaning piston (35) moves from bottom to top in the hole cleaning cylinder (32), the control valves on the upper right water inlet pipe (39) and the lower left water outlet pipe (393) are in a closed state, while the control valves on the lower right water inlet pipe (391) and the upper left water outlet pipe (392) are in an open state, so that when the hole cleaning piston (35) moves from bottom to top in the hole cleaning cylinder (32), the water inside the water tank (31) enters the hole cleaning cylinder (32) through the lower right water inlet pipe (391), and is discharged into the hole cleaning pipe through the upper left water outlet pipe (392). In the channel (37), when the channel cleaning piston (35) moves from top to bottom in the channel cleaning cylinder (32), the control valves on the upper right water inlet pipe (39) and the lower left water outlet pipe (393) are in an open state, while the control valves on the lower right water inlet pipe (391) and the upper left water outlet pipe (392) are in a closed state, so that when the channel cleaning piston (35) moves from top to bottom in the channel cleaning cylinder (32), the water inside the water tank (31) enters the channel cleaning cylinder (32) through the upper right water inlet pipe (39), and is discharged into the channel cleaning pipe (37) through the lower left water outlet pipe (393), and the channel cleaning piston (35) repeatedly moves up and down, so that the water inside the water tank (31) is continuously inserted into the grouting channel through the channel cleaning pipe (37), thereby realizing the cleaning operation of the inserted grouting channel; S3: Since water may accumulate in the grouting channel after cleaning, and the channel must be kept moist so that the cement slurry can be well combined with the hole wall, it is necessary to suck out the water accumulated in the grouting channel, and in the process of sucking out, the accumulated water can be more evenly contacted with the grouting channel, so that the cement slurry can be well combined with the hole wall, so as to facilitate the subsequent grouting operation. At this time, the first end of the channel cleaning pipe (37) is tapered and moves on the moving device (2), so that the channel cleaning pipe (37) After the head end is inserted into the grouting hole, it can effectively fit the grouting hole, so that the hole cleaning pipe (37) and the inserted grouting hole are in a sealed environment. At this time, the hole cleaning hydraulic cylinder (34) is driven to drive the hole cleaning piston (35) on the driving end of the hole cleaning hydraulic cylinder (34) to move up and down in the hole cleaning cylinder (32). When the hole cleaning piston (35) moves from bottom to top in the hole cleaning cylinder (32), the lower right water inlet pipe (391) and the upper left water outlet pipe (392) are opened. ) is in a closed state, while the control valves on the upper right water inlet pipe (39) and the lower left water outlet pipe (393) are in an open state, so that when the channel cleaning piston (35) moves from bottom to top in the channel cleaning cylinder (32), a suction force is formed on the grouting channel inserted. When the channel cleaning piston (35) moves from top to bottom in the channel cleaning cylinder (32), the control valves on the upper right water inlet pipe (39) and the lower left water outlet pipe (393) are in a closed state, while the lower right water inlet pipe ( 391) and the control valve on the upper left water outlet pipe (392) are in an open state, and at this time, a suction force is formed in the inserted grouting channel, and the channel cleaning piston (35) repeatedly moves up and down in the channel cleaning cylinder (32), so that the accumulated water in the grouting channel is sucked out by the suction force, and the accumulated water flows and contacts the grouting channel more evenly, so that the accumulated water in the inserted grouting channel is discharged, and the subsequent cement slurry is well combined with the hole wall, thereby improving the quality and efficiency of the product; S4: After the cleaning of the inside of the grouting channel is completed, when the moving device (2) drives the channel cleaning device (3) to move in the direction of blocking the channel, one end of the two moving rods (24) will slide a certain distance in the sliding grooves (42) on both sides of the conversion seat (41). When the two moving rods (24) slide to the ends of the sliding grooves (42) on both sides of the conversion seat (41), the two moving rods (24) will continue to move and will contact the conversion seat (41), thereby driving the conversion seat (41). 1) moving in the direction of the blocked channel, so as to drive the conversion device (4) to move in the direction of the blocked channel, thereby driving the channel blocking pipe (53) to be pressed together with the blocking pipe. After the moving channel blocking pipe (53) and the blocking pipe are pressed together, the driving pump (52) is operated to discharge the slurry stirred inside the stirring device (51) into the blocking pipe through the connecting pipe (55), and then into the just pressed blocking pipe, so as to facilitate the subsequent blocking operation of the blocked channel; S5: When the inside of the grouting pipe is cleaned, the extrusion plate (64) in the extrusion device (6) can be supported by the hole cleaning pipe (37) and pass through the hole blocking pipe (53) through the operation of the conversion device (4). When the mud stirred inside the stirring device (51) is discharged into the blocking pipe through the connecting pipe (55) by the driving pump (52) and flows into the just pressed blocking pipe, the extrusion plate (64) in the extrusion device (6) is supported by the hole cleaning pipe (37) through the operation of the conversion device (4). Through the action of the limit block (65), the extrusion piece (66) can only be pushed to move in the hole blocking pipe (53) in the blocking pipe direction, thereby pushing the mud inside the hole blocking pipe (53) into the blocking pipe, and the extrusion piece (66) is limited to block the mud in the blocking pipe from flowing back into the hole blocking pipe (53), waiting for a while. After a period of time, when the moving device (2) drives the channel cleaning device (3) to move away from the blocked channel, one end of the two moving rods (24) will slide a certain distance in the sliding grooves (42) on both sides of the conversion seat (41). At this time, the channel cleaning pipeline (37) and the conversion device (4) are not in contact. At the same time, the conversion device (4) drives the channel blocking device (5) to change direction without contacting the channel cleaning device (3). When the two moving rods (24) slide and contact the ends of the other side of the sliding grooves (42) on both sides of the conversion seat (41), the two moving rods (24) will contact the conversion seat (41) when they continue to move, thereby driving the conversion seat (41) to move away from the blocked channel, thereby driving the channel blocking device (5) on the conversion device (4) to separate from the blocked channel, and the extrusion rod (62) returns to its original position due to the rebound force of the extrusion spring (63), thereby achieving the blocking operation of the blocked pipeline. S6: After the cleaning of the grouting pipe is completed and the plugging of the plugging pipe is completed, it is necessary to perform grouting operation on the inside of the grouting pipe. At this time, the operation of the conversion device (4) drives the hole plugging device (5) to rotate, so that the limit block (65) faces the hole cleaning pipe (37), so that the operation of the moving device (2) causes the hole cleaning pipe (37) to lift the extrusion plate (64) through the hole plugging pipe (53), and the docking hole (38) on the hole cleaning pipe (37) just corresponds to the connecting pipe (55) connected to the hole plugging pipe (53), and is in a matching state. At this time, the head end of the hole cleaning pipe (37) is also converted and inserted into the grouting pipe, so that the stirring device (51) can be stirred by driving the pump (52). The slurry formed flows into the bore cleaning pipe (37) through the connecting pipe (55), thereby pressing the slurry into the grouting pipe through the bore cleaning pipe (37), thereby realizing the grouting operation in the grouting pipe; after the grouting operation is completed, the device is moved back to the original position, and there will be unsolidified slurry inside the bore cleaning pipe (37) and the bore plugging pipe (53), which is not convenient for the next grouting operation. At this time, the water inside the water tank (31) is discharged through the operation of the bore cleaning piston (35), and the head end of the bore cleaning pipe (37) is moved to the bore plugging pipe (53) through the operation of the moving device (2), thereby realizing the cleaning operation of the inside of the bore cleaning pipe (37) and the bore plugging pipe (53), so as to facilitate the next grouting operation.
