Description

Technical Field

[0001] The invention belongs to the technical field of curtain grouting fast positioning drilling, in particular to a curtain grouting fast positioning drilling device. Background Art

[0002] When constructing tunnels in areas with high altitudes and rich hydropower resources, the use of curtain grouting for advance sealing is almost an inevitable key construction process. At the same time, due to the great depth of the tunnel and the intense geological activities, the tunnel line is likely to encounter high geothermal problems, or even high-temperature hot spring water connected to the stratum fissures, with the highest water temperature reaching 65°C to 90°C. During the drilling process, conventional curtain grouting construction requires the input of high-pressure air or high-pressure air + water by the hollow drill rod to facilitate the discharge of hole slag. However, when encountering high-temperature hot spring water, a large amount of high-temperature water is sprayed out of the guide pipe, which deteriorates the construction environment. At the same time, the high-temperature water is sprayed on the drilling rig equipment, causing the engine oil and hydraulic oil to be heated and emulsified, aggravating equipment wear and even causing equipment paralysis.

[0003] Publication No. CN217950324U A curtain grouting construction device suitable for high-temperature hot spring water formations, including: a splash-proof unit and a grouting unit connected in the axial direction, wherein: the splash-proof unit includes an outer cover and a drainage bucket, wherein: the outer cover is a hollow shell with an open lower portion, and holes are provided at the front and rear ends of the shell and on the same axis, and the front end is an inlet, and the drainage bucket includes a bottom plate, the front and rear ends of the bottom plate are open, and the left and right ends are provided with vertical plates running forward and backward, each vertical plate is an isosceles triangle plate body, and one end of the tip is located at the rear end vertex of the bottom plate, the rear end of the bottom plate is connected to the rear end of the outer cover by a rotating shaft, and its front end extends to the front end of the outer cover, and the bottom plates at the left and right ends are connected to the left and right ends of the outer cover, and can slide up and down to change the opening size between the front end of the drainage bucket and the bottom of the outer cover.

[0004] In the above scheme, three groups of valves consisting of a gate valve, a drain valve, and a slurry inlet valve are provided. When drilling a grouting hole, the gate valve needs to be opened, and the drain valve and the slurry inlet valve need to be closed. When injecting cement mortar into the grouting hole, the gate valve needs to be closed and the slurry inlet valve needs to be opened. When cleaning the pipeline, the drain valve needs to be further opened. Therefore, when performing the above processes, the staff needs to coordinate the opening and closing of the gate valve, the drain valve, and the slurry inlet valve. Due to the large number of valves, the adjustment is not only cumbersome, but also time-consuming and labor-intensive, which reduces the efficiency of construction. For this reason, the present invention provides a curtain grouting rapid positioning drilling device. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve its technical problems is: a curtain grouting rapid positioning drilling device described in the present invention comprises a wire pipe and a drill rod, a valve is arranged at one end of the wire pipe, a slurry inlet main pipe is arranged at the upper end of the valve, a drainage bucket is arranged at one end of the valve, the drill rod passes through the drainage bucket, the valve and the wire pipe in sequence, a discharge port for discharging high-temperature water mixed hole slag is provided at the bottom of the drainage bucket, and the valve comprises: a valve body, a first docking nozzle arranged at one end of the valve body, the first docking nozzle is connected to the wire pipe, a second docking nozzle arranged at the other end of the valve body, the second docking nozzle is connected to the drainage bucket, a third docking nozzle arranged at the upper end of the valve body, the third docking nozzle is connected to the slurry inlet main pipe, a valve ball movably installed in the valve body, a channel is provided on the valve ball, a liquid outlet hole for discharging waste liquid is provided on one side of the channel, and a handle fixedly connected to the valve ball;

[0007] When drilling grouting holes, grouting and cleaning, the connection relationship between the slurry inlet main pipe, the wire pipe and the drainage bucket can be changed by simply adjusting the valve, which simplifies the operation of the staff and improves the efficiency of the construction.

[0008] Preferably, a flow diversion mechanism is provided in the drainage bucket, and the flow diversion mechanism comprises: a rotary sleeve, the rotary sleeve is rotatably mounted on the drainage bucket, six groups of conical plates hinged at equal angles on one end of the rotary sleeve, an external threaded sleeve screwed in the rotary sleeve, a receiving sleeve rotatably mounted in the external threaded sleeve, six groups of connecting rods, one end of the connecting rod is hinged to the receiving sleeve, the other end of the connecting rod is hinged to the conical plate, a sealing sleeve fixedly mounted in the receiving sleeve, the drill rod passes through the sealing sleeve, and the inner ring of the sealing sleeve fits the outer wall of the drill rod;

[0009] As the slurry inlet main pipe and the regulating valve are flushed clean, clean water enters the drainage bucket. Through the conical surface guiding effect of the conical sleeve, the cement mortar adhering to the surrounding areas of the drainage bucket is flushed clean by the clean water, making the inside of the drainage bucket cleaner.

[0010] Preferably, the diversion mechanism further comprises: a worm wheel, the worm wheel is fixedly sleeved on the other end of the rotary sleeve, a worm that meshes with the worm wheel, a horizontal bar is welded on the conical plate, and the worm is rotatably mounted on the diversion bucket;

[0011] As the conical sleeve rotates, the horizontal bars generate centrifugal force on the flushing clean water, causing the clean water to be thrown to a farther position around the drainage bucket, further making the drainage bucket cleaner.

[0012] Preferably, the wire tube comprises: a tube body, one end of the tube body is fixedly connected to the first docking nozzle, a fixed sleeve sleeved on the tube body, a rubber sleeve sleeved on the fixed sleeve, six groups of arc-shaped pressure-bearing plates fixedly connected to the inner ring of the rubber sleeve at equal angles, an internally threaded tube screwed on the tube body, a grouting secondary pipe fixedly mounted on the internally threaded tube for grouting, a pressure relief pipe fixedly mounted on the internally threaded tube for exhaust, and two groups of first through holes are provided at one end of the fixed sleeve, and the two groups of first through holes are respectively connected to the grouting secondary pipe and the pressure relief pipe;

[0013] After the rubber sleeve is squeezed, the rubber sleeve fits more closely to the inner wall of the hole, making the entire wire tube fit more closely to the hole, ensuring that the axes of the wire tube and the hole are in the same straight line, until the secondary slurry inlet pipe and the pressure relief pipe are respectively connected to the two groups of first through holes, and then the secondary slurry inlet pipe is connected to the grouting machine, and cement mortar passes through the secondary slurry inlet pipe and one group of first through holes in turn into between the pipe body and the inner wall of the hole. As the cement mortar enters between the pipe body and the inner wall of the hole, the air between the pipe body and the inner wall of the hole is pressed out from the pressure relief pipe until the space between the pipe body and the inner wall of the hole is filled with cement mortar, which not only makes grouting between the pipe body and the inner wall of the hole more convenient, but also ensures the construction effect of grouting and sealing.

[0014] Preferably, four groups of second through holes are provided at one end of the fixed sleeve, and one end of the internally threaded tube is fixedly connected to the four groups of guide pillars, and the guide pillars are movably plugged into the internally threaded tubes with the second through holes;

[0017] Since the volume of cement mortar passing through the pressure plate is much smaller than that of air, the pressure plate is subjected to a greater impact force from the cement mortar, causing the pressure plate and the guide shaft to move upward, and the guide shaft stretches the spring until the pressure plate blocks the fixed cover and the pin is inserted into the exhaust hole, preventing the cement mortar from being ejected from the pressure relief pipe, thereby avoiding a large amount of cement mortar waste.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. When drilling, grouting and cleaning grouting holes, the connection relationship between the slurry inlet main pipe, the wire pipe and the drainage bucket can be changed by adjusting the valve, which simplifies the operation of the staff and improves the construction efficiency.

[0020] 2. Before cleaning, in the initial state, the six groups of conical plates are in a separated state, and the external threaded sleeve is rotated. As the external threaded sleeve rotates, the external threaded sleeve moves together with the receiving sleeve, and the receiving sleeve pulls the six groups of conical plates to flip through the six groups of connecting rods, so that the six groups of conical plates are combined into a conical sleeve, and the cement mortar mixed with clean water entering the drainage bucket will directly impact the conical surface of the conical sleeve, and the cement mortar mixed with clean water is guided to the surrounding of the drainage bucket through the guidance of the conical surface. Similarly, when the slurry inlet main pipe and the regulating valve are flushed clean, clean water enters the drainage bucket, and the cement mortar adhering to the surrounding of the drainage bucket is flushed clean by the conical surface guiding effect of the conical sleeve, so that the inside of the drainage bucket is cleaned more.

[0021] 3. When installing the wire tube, insert the entire wire tube into the hole drilled on the stop wall, fix the fixing sleeve with a set of open-end wrenches, and rotate the tube body with another set of open-end wrenches. As the tube body rotates, the internal threaded tube will move toward the inside of the fixing sleeve, and the fixing sleeve will squeeze the six sets of arc-shaped pressure plates, so that the arc-shaped pressure plates squeeze the rubber sleeve. The rubber sleeve will be deformed by the squeezing, so that the hole end is blocked by the rubber sleeve. After the rubber sleeve is squeezed, the rubber sleeve fits more closely with the inner wall of the hole, so that the entire wire tube fits more closely with the hole, ensuring Ensure that the axes of the conductor pipe and the hole are in the same straight line until the secondary slurry inlet pipe and the pressure relief pipe are respectively connected to the two groups of first through holes, and then the secondary slurry inlet pipe is connected to the grouting machine, and the cement mortar passes through the secondary slurry inlet pipe and one group of first through holes in turn into the space between the pipe body and the inner wall of the hole. As the cement mortar enters the space between the pipe body and the inner wall of the hole, the air between the pipe body and the inner wall of the hole is pressed out from the pressure relief pipe until the space between the pipe body and the inner wall of the hole is filled with cement mortar, which not only makes grouting between the pipe body and the inner wall of the hole more convenient, but also ensures the construction effect of grouting and sealing.

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1

[0035] like Figures 1 to 3As shown, a curtain grouting fast positioning drilling device according to an embodiment of the present invention comprises a conductor pipe 1 and a drill rod 5. A valve 2 is arranged at one end of the conductor pipe 1, a slurry inlet main pipe 3 is arranged at the upper end of the valve 2, a drainage bucket 4 is arranged at one end of the valve 2, the drill rod 5 passes through the drainage bucket 4, the valve 2 and the conductor pipe 1 in sequence, and a discharge port 401 for discharging high-temperature water mixed hole slag is opened at the bottom of the drainage bucket 4. The valve 2 comprises: a valve body 201, a first butt nozzle 202 arranged at one end of the valve body 201, and a first butt nozzle 203. The nozzle 202 is connected to the wire pipe 1, a second nozzle 203 is arranged at the other end of the valve body 201, the second nozzle 203 is connected to the drainage bucket 4, a third nozzle 204 is arranged at the upper end of the valve body 201, the third nozzle 204 is connected to the slurry inlet main pipe 3, a valve ball 206 is movably installed in the valve body 201, a channel 2061 is provided on the valve ball 206, a liquid outlet hole 2062 for excreting waste liquid is provided on one side of the channel 2061, and a handle 205 is fixedly connected to the valve ball 206.

[0036] Specifically, the drill rod 5 is installed on the drilling rig, the slurry inlet main pipe 3 is connected to the grouting machine, the valve ball 206 is coated with a rubber layer to enhance the sealing between the valve ball 206 and the inner wall of the valve body 201, the inner diameter of the channel 2061 is larger than the outer diameter of the drill rod 5, and in the initial state, the two ends of the channel 2061 are respectively opposite to the first docking nozzle 202 and the second docking nozzle 203, and the third docking nozzle 204 is blocked by the valve ball 206. When it is necessary to drill a grouting hole, the wire pipe 1 is inserted into the hole drilled in advance on the slurry stop wall, and then the drill rod 5 is passed through the drainage bucket 4, the channel 2061, The wire pipe 1 is started, the drill rod 5 is started to rotate to open a grouting hole at the bottom of the hole, and the high-temperature water mixed with the hole slag produced by the drilling is discharged in the reverse direction along the drill rod 5, and passes through the wire pipe 1, the channel 2061, the drainage bucket 4 in sequence, and finally discharged from the drainage bucket 4 through the discharge port 401. When grouting is required, the drill rod 5 is withdrawn, and the handle 205 is turned so that the handle 205 drives the valve ball 206 to rotate 90 degrees along the inner cavity of the valve body 201, so that one end of the channel 2061 is facing the third docking nozzle 204, and the other end of the channel 2061 is blocked by the inner wall of the valve body 201, and the liquid outlet hole 2062 is facing the first docking nozzle 202, the grouting machine injects cement mortar into the valve body 201 through the grout inlet pipe 3, and the cement mortar passes through the third docking nozzle 204, the channel 2061, the liquid outlet 2062, the first docking nozzle 202, and the wire pipe 1 in sequence until it enters the grouting hole. When it is necessary to clean the grout inlet pipe 3 and the valve 2, the handle 205 is turned again to rotate the valve ball 206 back 180 degrees along the inner cavity of the valve body 201, so that one end of the channel 2061 is blocked by the inner wall of the valve body 201, and the other end of the channel 2061 is facing the third docking nozzle 204, the liquid outlet 2062, the first docking nozzle 202, and the wire pipe 1 until it enters the grouting hole. 2 is facing the second docking nozzle 203, and the grouting machine is changed to suck clean water. The clean water passes through the slurry inlet main pipe 3, the third docking nozzle 204, the channel 2061, the liquid outlet hole 2062, the second docking nozzle 203, and the drainage bucket 4 in sequence. Finally, the cement mortar mixed with the clean water is discharged from the drainage bucket 4 through the discharge port 401. Compared with the prior art, when drilling, grouting and cleaning the grouting hole, it is only necessary to adjust the valve 2 to change the connection relationship between the slurry inlet main pipe 3, the wire pipe 1 and the drainage bucket 4, which simplifies the operation of the staff and improves the construction efficiency.

[0037] like Figure 2 , Figure 4 , Figure 5As shown, a flow guide mechanism 6 is provided in the drainage bucket 4, and the flow guide mechanism 6 includes: a spin-on sleeve 601, the spin-on sleeve 601 is rotatably installed on the drainage bucket 4, six groups of conical plates 602 are hinged at one end of the spin-on sleeve 601 at equal angles, an external threaded sleeve 603 screwed in the spin-on sleeve 601, a socket sleeve 604 rotatably installed in the external threaded sleeve 603, six groups of connecting rods 605, one end of the connecting rod 605 is hinged to the socket sleeve 604, the other end of the connecting rod 605 is hinged to the conical plate 602, a sealing sleeve 606 fixedly installed in the socket sleeve 604, the drill rod 5 passes through the sealing sleeve 606, and the inner ring of the sealing sleeve 606 fits the outer wall of the drill rod 5.

[0038] Specifically, during the above cleaning, the cement mortar mixed with clean water enters the drainage bucket 4, and the cement mortar mixed with clean water will splash onto the inner wall of the drainage bucket 4, so that the drainage bucket 4 is covered with the cement mortar mixed with clean water. As the clean water is continuously injected, the slurry inlet main pipe 3 and the regulating valve 2 will be rinsed clean, and the clean water entering the drainage bucket 4 from the regulating valve 2 will be clean. Since the direction of the clean water discharged into the drainage bucket 4 remains unchanged, the direction of the clean water flushing the drainage bucket 4 remains unchanged, resulting in the cement mortar covered around the drainage bucket 4 cannot be thoroughly cleaned. Therefore, before cleaning, in the initial state, the six groups of conical plates 602 are in a separated state, and the external threaded sleeve 603 is rotated. As the external thread The sleeve 603 rotates, and the external threaded sleeve 603 moves together with the receiving sleeve 604. The receiving sleeve 604 pulls the six groups of conical plates 602 to flip through the six groups of connecting rods 605, so that the six groups of conical plates 602 are combined into a conical sleeve. The cement mortar mixed with clean water entering the drainage bucket 4 will directly impact the conical surface of the conical sleeve. Through the guidance of the conical surface, the cement mortar mixed with clean water is guided to the surrounding of the drainage bucket 4. Similarly, when the slurry inlet main pipe 3 and the regulating valve 2 are flushed clean, clean water enters the drainage bucket 4. Through the guiding effect of the conical surface on the conical sleeve, the cement mortar adhering to the surrounding of the drainage bucket 4 is flushed clean by clean water, so that the inside of the drainage bucket 4 is cleaned more cleanly.

[0039] Furthermore, the flow guide mechanism 6 also includes: a worm wheel 607, a worm wheel 607 fixing sleeve 102 installed on the other end of the rotating sleeve 601, a worm 608 meshing with the worm wheel 607, a horizontal bar 6021 welded on the conical plate 602, and the worm 608 is rotatably installed on the drainage bucket 4.

[0040] Specifically, when clean water flushes the conical surface on the conical sleeve, the worm 608 is rotated. As the worm 608 rotates, the worm wheel 607 rotates together with the spin-on sleeve 601 and the conical sleeve. Since the conical plate 602 is provided with a horizontal bar 6021, as the conical sleeve rotates, the horizontal bar 6021 generates centrifugal force on the flushing clean water, so that the clean water is thrown to a farther position around the drainage bucket 4, further making the drainage bucket 4 cleaned more thoroughly.

[0041] Embodiment 2

[0042] like Figure 6 and Figure 7 As shown, compared with Example 1, another implementation of the present invention is: the wire tube 1 includes: a tube body 101, one end of the tube body 101 is fixedly connected to the first docking nozzle 202, a fixed sleeve 102 sleeved on the tube body 101, a rubber sleeve 103 sleeved on the fixed sleeve 102, six groups of arc-shaped pressure-bearing plates 104 fixedly connected to the inner circle of the rubber sleeve 103 at equal angles, an internal threaded tube 105 screwed on the tube body 101, a slurry inlet secondary pipe 106 fixedly installed on the internal threaded tube 105 for grouting, a pressure relief pipe 107 fixedly installed on the internal threaded tube 105 for exhaust, and two groups of first through holes 1021 are opened at one end of the fixed sleeve 102, and the two groups of first through holes 1021 are respectively connected to the slurry inlet secondary pipe 106 and the pressure relief pipe 107.

[0043] Specifically, the rubber sleeve 103 is hollow and filled with air. The wire tube 1 plays a role in rapid positioning and guiding for the subsequent drilling of the drill rod 5 of the drilling rig for grouting. Since cement mortar needs to be poured between the outer wall of the wire tube 1 and the inner wall of the borehole, the inner diameter of the borehole is larger than the outer diameter of the wire tube 1. Therefore, when the wire tube 1 is placed in the borehole, the axis of the wire tube 1 deviates from the axis of the borehole. The drilling position of the drill rod 5 for grouting deviates from the axis of the borehole. If the inner diameter of the borehole is equal to the outer diameter of the wire tube 1, the inner diameter of the borehole is smaller than the outer diameter of the wire tube 1. The larger the difference, the greater the deviation of the grouting drilling position, which will affect the effect of the entire grouting plugging. If the numerical difference between the inner diameter of the borehole and the outer diameter of the wire tube 1 is small, it will be difficult to inject cement mortar between the outer wall of the guide tube and the inner wall of the borehole. Therefore, when installing the wire tube 1, after the entire wire tube 1 is inserted into the hole drilled in the stop wall, a set of open-end wrenches are used to fix the fixing sleeve 102, and another set of open-end wrenches are used to rotate the tube body 101. As the tube body 101 rotates, the internal threaded tube 105 will move toward the inside of the fixing sleeve 102, The fixing sleeve 102 will squeeze the six groups of arc-shaped pressure-bearing plates 104, so that the arc-shaped pressure-bearing plates 104 squeeze the rubber sleeve 103. The rubber sleeve 103 will be deformed by the squeezing, so that the hole end is blocked by the rubber sleeve 103. After the rubber sleeve 103 is squeezed, the rubber sleeve 103 fits more closely with the inner wall of the hole, so that the entire wire tube 1 fits more closely with the hole, ensuring that the axis of the wire tube 1 and the hole are on the same straight line, until the slurry inlet pipe 106 and the pressure relief pipe 107 are respectively connected with the two groups of first through holes 102. 1, and then connect the grouting secondary pipe 106 to the grouting machine, and the cement mortar enters between the pipe body 101 and the inner wall of the hole through the grouting secondary pipe 106 and one group of first through holes 1021 in sequence. As the cement mortar enters between the pipe body 101 and the inner wall of the hole, the air between the pipe body 101 and the inner wall of the hole is pressed out from the pressure relief pipe 107 until the space between the pipe body 101 and the inner wall of the hole is filled with cement mortar, which not only makes the grouting between the pipe body 101 and the inner wall of the hole more convenient, but also ensures the construction effect of grouting and plugging.

[0044] like Figure 8As shown, one end of the fixing sleeve 102 is provided with four groups of second through holes 1022 , one end of the internal threaded tube 105 is fixedly connected to four groups of guide pillars 1051 , and the guide pillars 1051 are movably plugged into the internal threaded tube 105 in the second through holes 1022 .

[0045] Specifically, the internal threaded tube 105 moves toward the fixing sleeve 102 , and the internal threaded tube 105 pushes the guide post 1051 to slide along the second through hole 1022 . The cooperation between the guide post 1051 and the second through hole 1022 guides the movement of the internal threaded tube 105 .

[0046] like Fig. 9 As shown, the pressure relief pipe 107 includes: a pipe 1071, the pipe 1071 is fixedly installed on the internal threaded pipe 105, a fixed cover 1072 fixedly installed on one end of the pipe 1071, a guide shaft 1073 movably plugged into the fixed cover 1072, a pressure plate 1074 fixedly connected to one end of the guide shaft 1073, a spring 1075 sleeved on the guide shaft 1073, two groups of pins 1076 fixedly installed on the lower end surface of the fixed cover 1072, two groups of exhaust holes 741 for ventilation are opened on the pressure plate 1074, the pins 1076 are used to block the exhaust holes 741, one end of the spring 1075 is fixedly connected to the upper end surface of the fixed cover 1072, and the other end of the spring 1075 is fixedly connected to the other end of the guide shaft 1073.

[0047] Specifically, the outer diameter of the pressure plate 1074 is smaller than the inner diameter of the pipe 1071, and the air between the pipe body 101 and the inner wall of the hole is discharged through the pressure relief pipe 107. When the space between the pipe body 101 and the inner wall of the hole is filled with cement mortar, the cement mortar will flow into the pressure relief pipe 107 and be ejected through the pressure relief pipe 107. When the staff finds that the cement mortar is ejected from the pressure relief pipe 107, even if the grouting machine is turned off, the cement mortar will be wasted during the process of turning off the grouting machine. Therefore, when the air between the pipe body 101 and the inner wall of the hole enters the pressure relief pipe 107, the air will flow along the pipe 1071. When the air contacts the pressure plate 1074, part of the air passes through the pressure plate 1074 and the pipe 1071. 71, and the other part is discharged through the exhaust hole 741. Secondly, the spring force of the spring 1075 offsets the impact force of the air on the pressure plate 1074, making the pressure plate 1074 unable to move until the cement mortar flows into the tube body 101. Since the cement mortar passing through the pressure plate 1074 is much smaller than the air, the pressure plate 1074 is subjected to a greater impact force of the cement mortar, causing the pressure plate 1074 to move upward together with the guide shaft 1073, and the guide shaft 1073 stretches the spring 1075 until the pressure plate 1074 blocks the fixing cover 1072, and the pin 1076 is inserted into the exhaust hole 741, so that the cement mortar cannot be ejected from the pressure relief pipe 107, thereby avoiding a large amount of cement mortar waste.

[0048] Working principle: When it is necessary to drill a grouting hole, insert the conductor pipe 1 into the hole drilled in advance on the grout-stopping wall, and then make the drill rod 5 pass through the drainage bucket 4, the channel 2061, and the conductor pipe 1 in sequence, start the drill rod 5 to rotate to open a grouting hole at the bottom of the hole, and the high-temperature water mixed with the hole slag produced by the drilling is discharged in the reverse direction along the drill rod 5, and passes through the conductor pipe 1, the channel 2061, the drainage bucket 4 in sequence, and finally discharged from the drainage bucket 4 through the discharge port 401;

[0049] When grouting is required, the drill rod 5 is withdrawn, and the handle 205 is turned, so that the handle 205 drives the valve ball 206 to rotate 90 degrees along the inner cavity of the valve body 201, so that one end of the channel 2061 faces the third docking nozzle 204, and the other end of the channel 2061 is blocked by the inner wall of the valve body 201, and the liquid outlet 2062 faces the first docking nozzle 202. The grouting machine injects cement mortar into the valve body 201 through the grout inlet main pipe 3, and the cement mortar passes through the third docking nozzle 204, the channel 2061, the liquid outlet 2062, the first docking nozzle 202, and the wire pipe 1 in sequence until it enters the grouting hole;

[0050] When it is necessary to clean the slurry inlet main pipe 3 and the valve 2, the handle 205 is turned again to rotate the valve ball 206 back 180 degrees along the inner cavity of the valve body 201, so that one end of the channel 2061 is blocked by the inner wall of the valve body 201, and the other end of the channel 2061 faces the third docking nozzle 204, and the liquid outlet 2062 faces the second docking nozzle 203. The grouting machine is changed to suck clean water, and the clean water passes through the slurry inlet main pipe 3, the third docking nozzle 204, the channel 2061, the liquid outlet 2062, the second docking nozzle 203, and the drainage bucket 4 in sequence, and finally the cement mortar mixed with clean water is discharged from the drainage bucket 4 through the discharge port 401;

[0051] Before cleaning, in the initial state, the six groups of conical plates 602 are in a separated state, and the external threaded sleeve 603 is rotated. As the external threaded sleeve 603 rotates, the external threaded sleeve 603 moves together with the receiving sleeve 604. The receiving sleeve 604 pulls the six groups of conical plates 602 to flip through the six groups of connecting rods 605, so that the six groups of conical plates 602 are combined into a conical sleeve. The cement mortar mixed with clean water entering the drainage bucket 4 will directly impact the conical surface of the conical sleeve, and the cement mortar mixed with clean water will be guided to the drainage bucket 4 through the guidance of the conical surface. Similarly, around the flow bucket 4, when the slurry inlet main pipe 3 and the regulating valve 2 are flushed, the clean water enters the drainage bucket 4, and the worm 608 is rotated at the same time. As the worm 608 rotates, the worm wheel 607 rotates together with the rotating sleeve 601 and the conical sleeve. Since the conical plate 602 is provided with a horizontal bar 6021, as the conical sleeve rotates, the horizontal bar 6021 generates centrifugal force on the flushed clean water, so that the clean water is thrown to a farther position around the drainage bucket 4, so that the cement mortar adhering to the surroundings of the drainage bucket 4 is flushed clean by the clean water;

[0052] When installing the wire pipe 1, after inserting the entire wire pipe 1 into the hole drilled in the mortar-stopping wall, use a set of open-end wrenches to fix the fixing sleeve 102, and use another set of open-end wrenches to screw the pipe body 101 to rotate. As the pipe body 101 rotates, the internal threaded pipe 105 will move toward the inside of the fixing sleeve 102, and the fixing sleeve 102 will squeeze the six sets of arc-shaped pressure-bearing plates 104, so that the arc-shaped pressure-bearing plates 104 squeeze the rubber sleeve 103. The squeezed rubber sleeve 103 will be deformed, so that the hole end is blocked by the rubber sleeve 103, until the slurry inlet secondary pipe 106 and the pressure relief pipe 107 are respectively connected to the two sets of first through holes 1021, and then the slurry inlet secondary pipe 106 is connected to the grouting machine, and cement mortar passes through the slurry inlet secondary pipe 106 and one of the first through holes 1021 in turn and enters between the pipe body 101 and the inner wall of the hole. As the cement mortar enters between the pipe body 101 and the inner wall of the hole, the gap between the pipe body 101 and the inner wall of the hole When the air enters the pressure relief pipe 107, the air will flow along the pipe 1071. When the air contacts the pressure plate 1074, part of the air flows out through the gap between the pressure plate 1074 and the inner wall of the pipe 1071, and the other part is discharged through the exhaust hole 741. Secondly, the spring force of the spring 1075 offsets the impact force of the air on the pressure plate 1074, so that the pressure plate 1074 cannot move until the cement mortar flows into the pipe body 101. Since the cement mortar passing through the pressure plate 1074 is much smaller than the air, the pressure plate 1074 is subjected to a greater impact force of the cement mortar, so that the pressure plate 1074 moves upward together with the guide shaft 1073, and the guide shaft 1073 stretches the spring 1075 until the pressure plate 1074 blocks the fixing cover 1072, and the pin 1076 is inserted into the exhaust hole 741, so that the cement mortar cannot be sprayed out from the pressure relief pipe 107.
