Description

Technical Field

[0001] The present invention belongs to the technical field of rock formation drilling engineering, and specifically relates to a water plugging treatment device and a water plugging treatment method for engineering construction. Background Art

[0002] In the rock formation drilling project, problems such as water seepage and water gushing are common. Usually, due to the existence of through water-conducting fissures or karst channels in the rock formation on the side wall of the construction surface, the rock is broken after processes such as diagenesis and weathering, increasing the water permeability of the rock formation, thereby accumulating groundwater or forming a channel for underground water flow. This phenomenon may cause water sources to seep into the construction surface, posing safety hazards. To prevent groundwater seepage and reduce water gushing problems, consolidation backfill grouting is usually adopted. By injecting slurry into the rock fissures or karst channels, the slurry diffuses along these channels and hardens, thereby forming a waterproof barrier. This barrier effectively intercepts the underground water flow outside the construction area, reduces the water gushing volume in the well, and reduces casualties or major accidents caused by water gushing.

[0003] In the prior art, when a water plugging device performs grouting water plugging work through a grouting pipe, some slurry will remain in the shunt pipe. When the shunt pipe is taken out and reused, it is necessary to clean the slurry inside the shunt pipe. If not cleaned in time, the slurry is likely to solidify, making it difficult to clean, affecting the subsequent construction efficiency, and possibly increasing the equipment maintenance cost. For this reason, the present invention provides a water plugging treatment device and a water plugging treatment method for engineering construction. Summary of the Invention

[0007] Preferably, a thimble is fixed to the end of the limiting plate away from the grouting pipe. An annular groove is formed in the side wall of the water-blocking block. A sealing film is fixed to the edge position of the annular groove. A water-swellable material is filled in the annular groove. The end of the thimble movably penetrates into the annular groove and is adjacent to the sealing film.

[0008] Preferably, a movable cavity is formed in the side wall of the limiting plate. A telescopic pipe is fixed to the inner wall of the movable cavity away from the grouting pipe. Water is filled in the telescopic pipe. The thimble is hollow. The thimble is communicated with the inside of the telescopic pipe through a one-way valve. A baffle is installed on the water-blocking block at a position adjacent to the central hole. The end of the baffle extends into the movable cavity.

[0009] Preferably, when the grouting pipe is taken out from the central hole, the two limiting plates are abutted against each other under the push of the first spring.

[0010] Preferably, the movable rod is bent in the middle to present an overall L shape, and an inclined portion is arranged at the middle position of the movable rod. The inclined surface of the wedge-shaped block and the inclined portion of the movable rod are both opposite to the central hole.

[0013] A water-blocking treatment method for engineering construction, which uses the above-mentioned water-blocking treatment device for engineering construction, includes the following steps: S1. Use drilling equipment to open a reserved hole at the water seepage position; S2. Connect the grouting pipe to the water-blocking block through the connecting component, sleeved the filter screen cover on the water-blocking block, and then send the water-blocking block and the filter screen cover into the reserved hole together through the grouting pipe; S3. Make the grouting pipe penetrate through the pipe perforation in the middle of the installation pipe and its end cover, and then thread-connect the installation pipe in the reserved hole; S4.

[0014] The beneficial effects of the present invention are as follows: 1. For a water-blocking treatment device and a water-blocking treatment method for engineering construction described in the present invention, a water-blocking operation is carried out on the water seepage position by setting a water-blocking component. First, use a drilling device to open a reserved hole at the water seepage position, and the water corresponding to the water seepage part can flow out along the reserved hole to avoid interfering with the subsequent solidification of the water-blocking slurry. Then, assemble the grouting pipe and the water-blocking block together through the connecting component, and then use the grouting pipe to send the water-blocking block and the filter screen cover into the reserved hole. Inject slurry into the reserved hole through the grouting equipment and the grouting pipe. The slurry accumulates in the reserved hole and flows into the water leakage fissure to fill the crack and achieve the water-blocking effect; By setting the water-blocking block, segmented grouting can be realized, so that the slurry can quickly fill the inner cavity of the water-blocking block, increase the pressure inside the cavity, and then enable the slurry to quickly fill the water seepage crack, improve the water-blocking efficiency, and enable the drilling work of the rock formation to be carried out smoothly.

[0015] 2. For a water-blocking treatment device and a water-blocking treatment method for engineering construction described in the present invention, as the slurry in the reserved hole increases, push the water-blocking block closer to the installation pipe until it contacts the installation pipe. At this time, the connection component's restriction on the grouting pipe can be released through the quick-release component to disassemble the grouting pipe and the installation pipe for convenient next use; And leave the water-blocking block in the reserved hole to continuously block the slurry leakage.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0021] Embodiment 1: As Figures 1 to 6 shown, a water plugging treatment device and a water plugging treatment method for engineering construction according to an embodiment of the present invention include a grouting body 1, a water plugging assembly and a quick-release assembly; A reserved hole 2 is opened on the grouting body 1 at the water seepage position; The water blocking component is arranged in the reserved hole 2 and is used to block the water leakage position of the grouting body 1. The water blocking component includes a mounting pipe 3 and a water blocking block 6. The mounting pipe 3 is threadedly installed in the reserved hole 2. A grouting pipe 4 is movably installed in the middle of the mounting pipe 3. The grouting pipe 4 is rotatably installed in the mounting hole 7 opened in the center of the water blocking block 6 through a connecting component. The water blocking block 6 is inserted into the innermost side of the reserved hole 2 through the grouting pipe 4; The connecting assembly includes a sliding cavity 13 symmetrically opened on both sides of the mounting hole 7, and a limit plate 9 is slidably arranged in the sliding cavity 13 on both sides, and an annular slot 8 adapted to the limit plate 9 is opened on the side wall of the grouting pipe 4, and a spring 14 is installed inside the sliding cavity 13 to reset the limit plate 9; The quick-release assembly is arranged on the water blocking block 6, and the grouting pipe 4 and the water blocking block 6 are separated by the quick-release assembly; During operation, a drilling device is used to open a reserved hole 2 at the water seepage position, and the water corresponding to the water seepage position can flow out along the reserved hole 2 to avoid interference with the subsequent curing of the water plugging slurry. Then, the two limit plates 9 are opened from one side of the installation hole 7, and the grouting pipe 4 is inserted from the other side of the installation hole to quickly complete the assembly of the grouting pipe 4 and the water plugging block 6. Then, the grouting pipe 4 is used to send the water plugging block 6 into the reserved hole 2, and then the installation pipe 3 is threadedly connected to the reserved hole 2. After that, the end of the grouting pipe 4 is connected to the grouting equipment. The slurry output port is connected, and the water-blocking slurry is injected into the side of the water-blocking block 6 away from the installation pipe 3 through the grouting equipment and the grouting pipe 4. The slurry accumulates in the reserved hole 2 and flows into the leaking cracks. The slurry solidifies in the cracks to fill the cracks and achieve the water-blocking effect. By setting the water-blocking block 6, segmented grouting can be achieved, so that the slurry can quickly fill the cavity on the side of the water-blocking block 6 away from the installation pipe 3, so that the internal pressure of the cavity is increased, and the slurry can quickly fill the seepage cracks and improve the water-blocking efficiency. As the slurry in the reserved hole 2 increases, the water blocking block 6 is pushed toward the installation pipe 3 until it contacts the installation pipe 3. At this time, the restriction of the connecting assembly on the grouting pipe 4 can be released by the quick-release assembly, so that the grouting pipe 4 and the installation pipe 3 can be disassembled for the next use; and the water blocking block 6 is left in the reserved hole 2 to continuously prevent slurry leakage.

[0022] A limiting groove 15 is formed on the side of the sliding cavity 13. A sliding block 16 is fixedly connected to the side wall of the end of the limiting plate 9 away from the grouting pipe 4. The quick-release assembly includes an installation cavity 20. A fixed sleeve 21 is fixedly connected inside the installation cavity 20. The installation cavity 20 communicates with the limiting groove 15. A wedge block 22 is slidably installed inside the fixed sleeve 21. Restricted by the shape of the inner wall of the fixed sleeve 21, the wedge block 22 can only move linearly along the fixed sleeve 21. The end of the wedge block 22 movably penetrates into the limiting groove 15. A connecting plate 25 is arranged at the end of the fixed sleeve 21. A second spring 26 is fixed between the connecting plate 25 and the inner wall of the installation cavity 20. A third spring 27 is fixed between the connecting plate 25 and the wedge block 22. A magnet 32 is fixedly connected to the end of the installation pipe 3. A through groove 23 is formed in the middle of the wedge block 22. A sliding groove 28 is formed in the side wall of the connecting plate 25. A movable rod 24 is slidably installed in the sliding groove 28. The movable rod 24 is bent in the middle so that the end away from the connecting plate 25 movably penetrates through the through groove 23. A sleeve 30 is fixedly connected to the side of the fixed sleeve 21 away from the movable rod 24. The sleeve 30 communicates with the fixed sleeve 21. A movable block 31 is hermetically slidably installed inside the sleeve 30. A pull rope 29 is fixed between the movable block 31 and the movable rod 24. The pull rope 29 penetrates through the fixed sleeve 21; During operation, the water-blocking block 6 moves towards the installation pipe 3 until it contacts the installation pipe 3. The magnet 32 at the end of the installation pipe 3 generates a suction force to attract the connecting plate 25 to move outwards. Then, the wedge block 22 is pulled to move through the third spring 27, so that the wedge block 22 moves towards the inside of the fixed sleeve 21, thereby compressing the air inside the fixed sleeve 21. The compressed air is pressed into the sleeve 30 on the side wall, and then the movable block 31 inside the sleeve 30 is pushed to slide. The movable block 31 pulls the movable rod 24 to move through the pull rope 29. The end of the movable rod 24 moves along the through groove 23 in the middle of the wedge block 22. And as the pull rope 29 moves, the side sliding block 16 is squeezed, and then the limiting plate 9 is driven to move towards the direction of the moving grouting pipe 4, so that the end of the limiting plate 9 disengages from the slot 8 on the outer wall of the grouting pipe 4, thereby removing the restriction on the grouting pipe 4. The grouting pipe 4 can be quickly disassembled, which is convenient for the next use. At this time, the water-blocking block 6 remains in the reserved hole 2 to continuously block the leakage of the slurry; In addition, when the movable rod 24 contacts the end of the fixed sleeve 21, an impact feeling is generated to prompt the operator to quickly pull out the grouting pipe 4. Due to the friction force between the wedge block 22 and the inner wall of the fixed sleeve 21, the wedge block 22 continues to slowly move towards the inside of the fixed sleeve 21, leaving more time for the operator to take out the grouting pipe 4, and the movement of the sliding block 16 is continuously blocked during the process.

[0023] One end of the limiting plate 9 away from the grouting pipe 4 is fixed with a thorn needle 18. An annular groove 17 is formed in the side wall of the water blocking block 6. A sealing film 19 is fixed at the edge position of the annular groove 17. The annular groove 17 is filled with a water-swellable material. The end of the thorn needle 18 movably penetrates into the annular groove 17 and is adjacent to the sealing film 19; During operation, when the limiting plates 9 on both sides move away from the grouting pipe 4, the thorn needle 18 is synchronously driven to move. The sealing film 19 is punctured by the thorn needle 18, so as to release the water-swellable material (such as bentonite) in the annular groove 17. The water-swellable material contacts the inner wall of the reserved hole 2 and the water in the slurry, and its volume becomes larger, thereby blocking the gap between the water blocking block 6 and the inner wall of the reserved hole 2, and further preventing the slurry from leaking.

[0024] An activity cavity 10 is formed in the side wall of the limiting plate 9. A telescopic pipe 12 is fixed to the inner wall of the activity cavity 10 away from the grouting pipe 4. The telescopic pipe 12 is filled with water. The thorn needle 18 is hollow. The thorn needle 18 is communicated with the inside of the telescopic pipe 12 through a one-way valve. A baffle 11 is installed on the water blocking block 6 at a position adjacent to the central hole. The end of the baffle 11 extends into the activity cavity 10; During operation, when the limiting plates 9 on both sides move towards the middle of the mounting hole 7, the baffle 11 blocks the movement of the telescopic pipe 12, and then squeezes the telescopic pipe 12, so that the water inside the telescopic pipe 12 is sprayed into the expansion material through the hollow thorn needle 18 to promote the swelling of the expansion material; and the limiting plate 9 synchronously drives the thorn needle 18 to move together, so that the water sprayed from the thorn needle 18 can contact more expansion material, so as to improve the swelling effect and further improve the sealing effect.

[0025] When the grouting pipe 4 is taken out from the central hole, the limiting plates 9 on both sides are abutted against each other under the push of the first spring 14; during operation, when the wedge block 22 completely moves into the fixed sleeve 21, it no longer blocks the slider 16. At this time, under the push of the first spring 14, the limiting plates 9 on both sides are driven to move towards the middle, and the limiting plates 9 on both sides are abutted against each other to block the mounting hole 7, which can prevent the slurry from leaking out of the mounting hole 7 and make the slurry better solidify in the reserved hole 2; In addition, the activity cavity 10 on the limiting plate 9 is set to be non-penetrating, so that the limiting plate 9 remains intact and can effectively block the leakage of the slurry.

[0026] The movable rod 24 is bent from the middle and integrally presents an L shape, and an inclined portion is provided at the middle position of the movable rod 24. The inclined surface of the wedge block 22 and the inclined portion of the movable rod 24 are both opposite to the central hole. During operation, when installing the limit plate 9 into the sliding cavity 13, first place the first spring 14, and then insert the limit plate 9 into the sliding cavity 13. When pushing the limit plate 9 inward, the slider 16 on the side of the limit plate 9 first contacts the inclined portion of the movable rod 24, pushing the movable rod 24 to move towards the inside of the movable cavity 10. Then, when contacting the inclined surface of the wedge block 22, the wedge block 22 is pushed to move towards the inside of the fixed sleeve 21. After that, the slider 16 can completely pass by the wedge block 22, and under the action of the second spring 26 and the third spring 27, the wedge block 22 is driven to reset, blocking the slider 16 from moving back, thereby restricting the limit plate 9 to be installed inside the sliding cavity 13.

[0027] A filter screen cover 5 is slidably sleeved on the outer side of the water blocking block 6. During operation, first sleeve the filter screen cover 5 on the outer side of the water blocking block 6, and then push the water blocking block 6 and the filter screen cover 5 into the reserved hole 2 together through the grouting pipe 4. The filter screen cover 5 fits against the inner wall of the reserved hole 2, which can support the inner wall of the reserved hole 2 and prevent the crack from expanding when water leaks out from the water seepage part.

[0028] Embodiment 2: As Figure 1 and Figure 2 shown, compared with Embodiment 1, another implementation manner of the present invention is that an end cover is detachably installed at the end of the installation pipe 3, and a pipe through hole adapted to the grouting pipe 4 is opened in the middle of the end cover. During operation, by providing the end cover to support the grouting pipe 4, the grouting pipe 4 is more stable during use.

[0029] As Figure 7 shown, a water blocking treatment method for engineering construction uses the above-mentioned water blocking treatment device for engineering construction, including the following steps: S1. Use a drilling device to open a reserved hole 2 at the water seepage position; S2. Connect the grouting pipe 4 to the water blocking block 6 through a connecting component, sleeve the filter screen cover 5 on the water blocking block 6, and then send the water blocking block 6 and the filter screen cover 5 into the reserved hole 2 together through the grouting pipe 4; S3. Make the grouting pipe 4 penetrate through the installation pipe 3 and the pipe through hole in the middle of its end cover, and then thread the installation pipe 3 onto the reserved hole 2; S4. Connect the end of the grouting pipe 4 to the slurry output port of the grouting device, and inject slurry through the grouting device and the grouting pipe 4 to the side of the water blocking block 6 away from the installation pipe 3. The slurry accumulates in the reserved hole 2 and flows into the leakage fissures to fill the cracks and achieve the water blocking effect; S5. As the slurry in the reserved hole 2 increases, push the water blocking block 6 towards the installation pipe 3 until it contacts the installation pipe 3; S6. Automatically trigger the quick-release component through magnetic force, driving the limiting plates 9 on both sides to move in opposite directions, so as to release the restriction on the grouting pipe 4, and then the grouting pipe 4 and the installation pipe 3 can be disassembled; S7. The limiting plate 9 synchronously drives the thorn needle 18 to move. The sealing film 19 is punctured by the thorn needle 18, and the water-swellable material inside the annular groove 17 comes into contact with water and expands in volume, and then the movable block 31 is stably restricted in the reserved hole 2; S8. Push the limiting plates 9 on both sides to abut against each other through the first spring 14 to close the installation hole 7 and prevent the slurry from leaking; S9. Wait for the slurry to solidify, and then completely fill the reserved hole 2 to complete the water blocking work.

7. An apparatus for water blocking treatment in engineering construction according to claim 6, characterized in that: A filter screen cover (5) is slidably sleeved on the outer side of the water blocking block (6).

8. An anti-seepage treatment device for engineering construction according to claim 7, characterized in that: The end of the installation pipe (3) is detachably provided with an end cover, and a pipe through hole adapted to the grouting pipe (4) is formed in the middle of the end cover.

9. A water plugging treatment method for engineering construction, which uses a water plugging treatment device for engineering construction described in claim 8, and is characterized in that: It includes the following steps: S1. Use a drilling device to open a reserved hole (2) at the water seepage position; S2. Connect the grouting pipe (4) and the water blocking block (6) through a connecting component, sleeved the filter screen cover (5) on the water blocking block (6), and then send the water blocking block (6) and the filter screen cover (5) into the reserved hole (2) together through the grouting pipe (4); S3. Make the grouting pipe (4) penetrate through the installation pipe (3) and the pipe through hole in the middle of its end cover, and then thread the installation pipe (3) onto the reserved hole (2); S4. Connect the end of the grouting pipe (4) to the slurry output port of the grouting device, and inject slurry through the grouting device and the grouting pipe (4) to the side of the water blocking block (6) away from the installation pipe (3). The slurry accumulates in the reserved hole (2) and flows into the water leakage crack to fill the crack and achieve the water blocking effect.

10. A water plugging treatment method for engineering construction according to claim 9, characterized in that: This method further includes: S5. As the slurry in the reserved hole (2) increases, push the water blocking block (6) closer to the installation pipe (3) until it contacts the installation pipe (3); S6. Automatically trigger the quick-release component through the magnetic force, drive the two limiting plates (9) to move in opposite directions to release the restriction on the grouting pipe (4), and then disassemble the grouting pipe (4) and the installation pipe (3); S7. The limiting plate (9) synchronously drives the thorn needle (18) to move, pierce the sealing film (19) through the thorn needle (18), and the water-swellable material inside the annular groove (17) contacts with water and its volume increases, thereby stably restricting the movable block (31) in the reserved hole (2); S8. Push the two limiting plates (9) to abut against each other through the first spring (14) to close the installation hole (7) and prevent slurry leakage; S9. Wait for the slurry to solidify, and then completely fill the reserved hole (2), that is, complete the water blocking work.
