Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water channel leakage plugging, in particular to a water conveying trunk channel leakage point plugging device and method. BACKGROUND

[0002] As a key infrastructure in the fields of agricultural irrigation and urban water supply, the water conveying trunk channel is prone to leakage points in the channel body (especially the joint part of the soil channel and the concrete channel) due to factors such as geological subsidence, water flow erosion, and biological erosion during long-term use. If not plugged in time, it may cause chain problems such as channel slope collapse, soil salinization, and water resource waste. In the prior art, a group of grouting holes are drilled in advance at the dam body leakage point, and then a grouting head is used to inject plugging slurry into the grouting hole.

[0003] However, in the plugging operation of the prior art, since the drilled grouting hole is connected with the soil retaining slope, the water flow in the channel may impact the soil retaining slope, which may cause soil loss and collapse of the soil retaining slope. The collapsed soil may enter the grouting hole, and in the subsequent grouting operation, the plugging cavity may be formed due to the soil in the grouting hole, which affects the plugging quality. In addition, after grouting plugging in the prior art, the left side of the plugging plate is prone to residual grouting gaps due to the pulling out of the grouting head. For the residual grouting gaps, the prior art generally uses manual grouting, but the effect of manual grouting may be low in efficiency, and the grouting material after grouting may not be fully mixed with the initial grouting material, which may not be uniformly filled, and the grouting quality and effect need to be further improved.

[0015] Further, a second magnet is fixedly connected to the first sliding plug, and a second electromagnet is fixedly connected in the second storage cavity, and the second magnet is attracted to the second electromagnet.

[0016] In order to enable the first sliding plug to be quickly reset, further, a first spring is fixedly connected to the first sliding plug, and one end of the first spring away from the first sliding plug is fixedly connected to an inner side wall of the second storage cavity.

[0017] In order to improve the stability of the sliding of the blocking plate, further, a sliding groove is formed in the grouting head, a sliding block is slidably connected in the sliding groove, the sliding block is fixedly connected to the blocking plate, an elastic pull rope is fixedly connected to the sliding block, and one end of the elastic pull rope away from the sliding block is fixedly connected to an inner side wall of the sliding groove.

[0018] Furthermore, a third electromagnet is fixedly connected to the reinforcing baffle, the slider is a magnetic block, the third electromagnet attracts the slider, and a fourth electromagnet is fixedly connected to the groove, the fourth electromagnet attracts the slider.

[0019] In order to enable the second slide to quickly reset, a second spring is further fixedly connected to the second slide, and the end of the second spring away from the second slide is fixedly connected to the bottom wall of the slide cavity.

[0020] A method for sealing seepage points in a water conveyance canal, using the aforementioned sealing equipment, comprises the following steps:

[0021] Step 1: Workers use a drilling machine to drill grouting holes at the seepage points on the canal slope, and then move the vehicle to the grouting location.

[0022] Step 2: The staff member holds the grouting head and dives underwater, inserting the grouting head into the grouting hole. At this time, the reinforcing baffle is located at the farthest end of the grouting hole.

[0023] Step 3: Inflate the air delivery chamber through the third air supply pipe. At this time, the first airbag inflates and presses against the inner wall of the grouting hole. Excess gas is input into the first storage chamber after passing through the first airbag. The material in the first storage chamber is sprayed out and expands to fill the gap between the channel slope and the reinforcing baffle.

[0024] Step 4: The reinforcing baffle separates from the sealing plate, the sealing plate slides along the grouting head, and the second airbag inflates and abuts against the inner wall of the grouting hole;

[0025] Step 5: Two sets of material conveying pipes respectively input grout material A and grout material B into the grouting head, and then spray the mixed grout material into the grouting hole through the grouting head;

[0026] Step 6: The staff pulls the grouting head backward, and the grouting hole is gradually filled and sealed with grout.

[0027] Step 7: Finally, the staff pulls the grouting head backward, and the material stored in the second storage chamber is squeezed out to fill the grouting gap remaining on the left side of the sealing plate.

[0028] Step 8: After the grout has pre-set, the staff removes the grouting head to complete the sealing grouting.

[0029] Compared with the prior art, the present invention provides a seepage point sealing device and method for water conveyance main canals, which has the following beneficial effects:

[0030] After the grouting head is inserted into the grouting hole, the first airbag in this invention quickly inflates and presses against the inner wall of the grouting hole, achieving immediate fixation of the reinforcing baffle and effectively preventing the soil of the retaining slope from collapsing into the grouting hole. At the same time, the excess gas in the first airbag drives liquid A and liquid B in the first storage chamber to spray out and mix. After mixing, they quickly fill the gap between the reinforcing baffle and the retaining slope, forming a seepage-proof and solidified layer that is tightly bonded to the soil, effectively blocking the scouring path of water flow on the retaining slope and preventing soil loss into the grouting hole.

[0031] This invention features a second storage chamber within the sealing plate. During grouting, some grout naturally flows into this chamber and pushes the first sliding plug to compress the first spring. When grouting is complete and the grouting head is pulled out, the second electromagnet is de-energized, and the spring force generated by the reset of the first spring pushes the first sliding plug, automatically squeezing out the grout stored in the second storage chamber to precisely fill the gap on the left side of the sealing plate formed by the withdrawal of the grouting head. This eliminates the need for manual secondary grouting, solving the problems of low efficiency and uneven mixing in existing technologies, and improving the overall grouting quality and the durability of the sealing effect.

[0032] This invention utilizes a pneumatic linkage structure between the second storage chamber, the sliding chamber, and the scraper. During the grouting process, as the grout is injected, it pushes the first sliding plug, and the compressed gas enters the sliding chamber through the fifth air supply pipe, driving the scraper to move downward and adhere tightly to the inner wall of the grouting hole. When the worker moves the grouting head outward, the scraper can simultaneously scrape out a small amount of residual soil and mud generated by the slight collapse of the retaining slope in the grouting hole, preventing impurities from forming an isolation layer in the grouting hole, ensuring that the injected grout can be tightly bonded to the hole wall, and further eliminating the hidden danger of sealing voids.

Detailed Implementation

[0046] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0047] Example 1: Refer to Figures 1-8 A seepage point sealing device for a water conveyance canal includes two sets of conveying pipes 402 connected to the vehicle body 1, and also includes a connecting seat 4021 fixedly connected to a grouting pipe 202, the connecting seat 4021 being connected to the conveying pipe 402.

[0048] Grouting head 2 is fixedly connected to grouting pipe 202, and grouting head 2 is connected to grouting pipe 202;

[0049] A reinforcing baffle 5 is detachably connected to the grouting head 2; a first airbag 7 is fixedly connected to the reinforcing baffle 5; multiple sets of through holes 501 and a first material storage chamber 502 are opened on the reinforcing baffle 5; a nozzle 5021 is fixedly connected to the reinforcing baffle 5; the nozzle 5021 is connected to the first material storage chamber 502.

[0050] The sealing plate 6 is slidably connected to the grouting head 2, and the reinforcing baffle 5 is connected to the sealing plate 6; a second material storage cavity 601 is provided in the sealing plate 6, and a first sliding plug 6014 is slidably connected in the second material storage cavity 601.

[0051] The sealing plate 6 also has a sliding cavity 603, which is connected to the second storage cavity 601; a second sliding plug 6031 is slidably connected in the sliding cavity 603, and a connecting rod 6033 is fixedly connected to the second sliding plug 6031. A scraper 13 is fixedly connected to the end of the connecting rod 6033 away from the second sliding plug 6031.

[0052] It should be noted that a pressure relief valve is also provided on the side wall of the second airbag 8. When the grouting head 2 is pulled out, the staff opens the pressure relief valve on the second airbag 8, so that the second airbag 8 will no longer press against the side wall of the grouting hole, making it easier for the grouting head 2 to be pulled out.

[0053] Reference Figures 1-3 The vehicle body 1 is also fixedly connected to a grouting pump 4, an air pump 3 and a storage tank 10. The grouting pump 4 has a grouting pipe 401 connected to its grouting end, which is connected to the storage tank 10. The grouting pump 4 has a discharge end connected to a conveying pipe 402. The air pump 3 has an air supply pipe 301 connected to its air outlet end, which is connected to a third air supply pipe 902 and is used to replenish air to the first airbag 7 and the second airbag 8.

[0054] An air supply chamber 504 is provided in the reinforcing baffle 5. A second air supply pipe 5042 is fixedly connected in the reinforcing baffle 5. One end of the second air supply pipe 5042 is connected to the air supply chamber 504, and the other end of the second air supply pipe 5042 is connected to the first airbag 7. A first air supply pipe 701 is fixedly connected in the reinforcing baffle 5. One end of the first air supply pipe 701 is connected to the first airbag 7, and the other end of the first air supply pipe 701 is connected to the first storage chamber 502.

[0055] Reference Figure 6 In practice, the first gas supply pipe 701 is equipped with a commercially available one-way pressure valve.

[0056] A connecting pipe 5041 is fixedly connected to the reinforcing baffle 5, and the connecting pipe 5041 is connected to the air delivery chamber 504. A third air supply pipe 902 is fixedly connected to the sealing plate 6, and a plug 9 is fixedly connected to the third air supply pipe 902. The plug 9 is connected to the connecting pipe 5041. A fourth air supply pipe 14 is fixedly connected to the side wall of the third air supply pipe 902, and the fourth air supply pipe 14 is connected to the second airbag 8.

[0057] Reference Figure 6 , Figure 7 In practice, a one-way air inlet valve is installed on the connecting pipe 5041, and a commercially available solenoid valve is installed on the fourth air supply pipe 14.

[0058] A first magnet 503 is fixedly connected to the reinforcing baffle 5, and a first electromagnet 602 is fixedly connected to the sealing plate 6. The first magnet 503 and the first electromagnet 602 are attracted to each other.

[0059] A second magnet 6013 is fixedly connected to the first slide plug 6014, and a second electromagnet 6012 is fixedly connected to the second storage cavity 601. The second magnet 6013 and the second electromagnet 6012 are attracted to each other.

[0060] A first spring 6011 is fixedly connected to the first slide plug 6014, and the end of the first spring 6011 away from the first slide plug 6014 is fixedly connected to the inner wall of the second storage cavity 601.

[0061] Reference Figure 6 The first spring 6011 can be quickly reset by setting it.

[0062] The grouting head 2 has a groove 201, and a slider 2011 is slidably connected in the groove 201. The slider 2011 is fixedly connected to the sealing plate 6. An elastic pull rope 11 is fixedly connected to the slider 2011, and the end of the elastic pull rope 11 away from the slider 2011 is fixedly connected to the inner wall of the groove 201.

[0063] By allowing the slider 2011 to slide in the groove 201, the stability of the sealing plate 6 sliding on the grouting head 2 can be improved.

[0064] The elastic pull rope 11 can be used to pull the slider 2011 to slide backward quickly, so that the slider 2011 can be attracted to the fourth electromagnet 2012 quickly.

[0065] A third electromagnet 505 is fixedly connected to the reinforcing baffle 5. The slider 2011 is a magnetic block. The third electromagnet 505 and the slider 2011 are attracted to each other. A fourth electromagnet 2012 is fixedly connected to the slide groove 201. The fourth electromagnet 2012 and the slider 2011 are attracted to each other.

[0066] Reference Figures 3-4 , Figure 6 , Figure 7 , Figure 12 Before use, the staff connects the reinforcing baffle 5 to the sealing plate 6. After the first electromagnet 602 is energized, it attracts the first magnet 503. At this time, the plug 9 is inserted into the connecting tube 5041 to complete the assembly.

[0067] Reference Figures 3-12 During grouting, the worker holds the grouting head 2 underwater and inserts it into the grouting hole. At this time, the reinforcing baffle 5 and the sealing plate 6 move synchronously. After the grouting head 2 is inserted a certain distance, the reinforcing baffle 5 moves to the farthest end of the grouting hole. At this time, the air pump 3 is started. The air pump 3 injects air into the air delivery chamber 504 through the air delivery pipe 301 and the third air delivery pipe 902. The gas injected into the air delivery chamber 504 is then input into the first airbag 7 through the second air delivery pipe 5042. After the first airbag 7 is inflated, it bulges up and presses against the inner wall of the grouting hole. As gas is continuously injected, the air pressure in the first airbag 7 reaches the threshold set by the pressure valve. At this time, the one-way pressure valve on the first air supply pipe 701 opens, and the excess gas in the first airbag 7 enters the first storage chamber 502 through the first air supply pipe 701. At this time, the expanded material in the first storage chamber 502 will be sprayed out through the nozzle 5021. After the expanded material is sprayed out, it expands and fills the gap between the filling channel slope and the reinforcing baffle 5.

[0068] It should be noted that the gas flow rate of the first gas supply pipe 701 is equal to the gas injection flow rate of the second gas supply pipe 5042.

[0069] It should also be noted that multiple sets of first storage chambers 502 are evenly distributed on the reinforcing baffle 5, and adjacent sets of first storage chambers 502 store liquid A and liquid B respectively; when liquid A and liquid B are sprayed out and mixed, they will gel and expand, thereby filling the gap between the filling channel slope and the reinforcing baffle 5.

[0070] In practice, solution A can be commercially available acrylate monomers, and solution B can be a commercially available initiator, specifically methyl ethyl ketone peroxide.

[0071] Reference Figures 5-12 After the expanded material solidifies, the first electromagnet 602 and the third electromagnet 505 are de-energized. At this time, the first electromagnet 602 is no longer attracted to the first magnet 503, and the slider 2011 is no longer attracted to the third electromagnet 505. Under the pulling force of the elastic rope 11, the slider 2011 will drive the sealing plate 6 to slide backward. After the sealing plate 6 slides a certain distance, the slider 2011 slides to the maximum limit in the slide groove 201 and is attracted to the energized fourth electromagnet 2012. At this time, the solenoid valve on the fourth gas supply pipe 14 is opened, and the gas supplied will be filled into the second air bag 8 through the fourth gas supply pipe 14. The second air bag 8 will be inflated and pressed against the inner wall of the grouting hole.

[0072] Reference Figures 3-8 During grouting, the staff starts two sets of grouting pumps 4. The two sets of grouting pumps 4 will draw grouting material A and grouting material B from the two sets of storage tanks 10, and pump the two sets of grouting materials into the grouting head 2, and then spray them into the grouting hole through the grouting head 2.

[0073] As the slurry is continuously injected, the pressure on the left side of the sealing plate 6 will gradually increase. When the pressure on the left side of the sealing plate 6 reaches the threshold, the sealing plate 6 and the grouting head 2 will be squeezed and slid to the right simultaneously. At this time, the slurry will also flow into the second storage chamber 601 and squeeze the first sliding plug 6014 in the second storage chamber 601. After being squeezed, the first sliding plug 6014 will slide to the right and squeeze the gas in the second storage chamber 601. After the first sliding plug 6014 slides a certain distance, the second magnet 6013 on the first sliding plug 6014 will attract the second electromagnet 6012 after it is energized.

[0074] As the sealing plate 6 and the grouting head 2 are simultaneously squeezed and begin to slide to the right, the workers begin to pull the grouting head 2 outward, and then gradually begin to perform grouting operations into the grouting hole.

[0075] Reference Figure 8 The sealing plate 6 is fixedly connected to the fifth gas supply pipe 604. One end of the fifth gas supply pipe 604 is connected to the second storage chamber 601, and the other end of the fifth gas supply pipe 604 is connected to the sliding chamber 603.

[0076] Reference Figures 6-8The compressed gas in the second storage chamber 601 at the bottom is also input into the sliding chamber 603 through the fifth gas supply pipe 604. The gas input into the sliding chamber 603 will compress and push the second sliding plug 6031 and the connecting rod 6033 to move, thereby pushing the scraper 13 to move down. After the scraper 13 moves down a certain distance, the scraper 13 will be in contact with the inner wall of the grouting hole. In the subsequent grouting process, when the worker moves the grouting head 2 outward, the scraper 13 can also scrape out the impurities that may be deposited on the bottom wall of the grouting hole due to drilling or soil erosion, thereby ensuring the compactness of the subsequent grouting and reducing the occurrence of voids after grouting.

[0077] Reference Figures 5-7 After grouting is completed, the fourth electromagnet 2012 is de-energized. At this time, the fourth electromagnet 2012 is no longer attracted to the slider 2011, and the second airbag 8 is still inflated and pressed against the side wall of the grouting hole. The operator pulls the grouting head 2 outward and simultaneously de-energizes the second electromagnet 6012. At this time, under the restoring force of the first spring 6011, the first spring 6011 will push the first sliding plug 6014 to reset, thereby pushing out the grout stored in the second storage chamber 601, and filling the grouting gap left on the left side of the sealing plate 6 due to the removal of the grouting head 2, ensuring the overall compactness and stability of the grouting. This improves the sealing effect.

[0078] In practical implementation, by using the slurry stored in the second storage chamber 601 to fill the grouting gap left on the left side of the sealing plate 6 due to the removal of the grouting head 2, it can ensure that the grouting gap is fully filled by the slurry reserved in the second storage chamber 601. On the other hand, it can solve the problem that in actual operation, when the grouting head 2 is being pulled out while grouting, the staff cannot effectively control the amount of grouting, which may lead to over-grouting and squeezing the sealing plate 6 out of the grouting hole. This improves the stability of grouting and the tightness of gap filling.

[0079] A second spring 6032 is fixedly connected to the second slide plug 6031, and the end of the second spring 6032 away from the second slide plug 6031 is fixedly connected to the bottom wall of the slide cavity 603.

[0080] The second spring 6032 enables the second slider 6031 to be quickly reset.

[0081] Reference Figure 8 In practice, a pressure relief pipe 6034 is also fixedly connected to the sealing plate 6, and the pressure relief pipe 6034 is connected to the sliding cavity 603.

[0082] It should be noted that the pressure relief pipe 6034 is equipped with a commercially available electromagnetic pressure relief valve.

[0083] The pressure relief pipe 6034 prevents excessive air pressure in the sliding cavity 603 from causing the scraper 13 to be damaged due to excessive downward pressure.

[0084] Example 2: A method for sealing seepage points in a water conveyance canal, using sealing equipment, and the steps are as follows:

[0085] Step 1: The staff uses a drilling machine to drill grouting holes at the seepage points on the canal slope. The diameter of the drill hole is slightly larger than the outer diameter of the grouting head 2. After drilling, the residual mud and sand in the hole are flushed with low-pressure clean water, and then the vehicle body 1 is moved to the grouting position.

[0086] Step 2: The staff assembles the reinforcing baffle 5 and the sealing plate 6, then holds the grouting head 2 and dives underwater, inserting the grouting head 2 into the grouting hole. At this time, the reinforcing baffle 5 and the sealing plate 6 will move synchronously. After the grouting head 2 is inserted a certain distance, the reinforcing baffle 5 moves to the farthest end of the grouting hole. At this time, the air pump 3 is started.

[0087] Step 3: Gas enters the gas delivery chamber 504 through the gas delivery pipe 301, the third gas supply pipe 902, and the connecting pipe 5041, and then fills the first airbag 7 through the second gas supply pipe 5042; the first airbag 7 expands to press against the hole wall, thereby fixing the reinforcing baffle 5. When the internal pressure of the first airbag 7 reaches the threshold of the one-way pressure valve, the excess gas enters the first storage chamber 502 through the first gas supply pipe 701, pushing liquids A and B to be sprayed out from the nozzle 5021 and mixed; the mixed material gel expands, filling the gap between the reinforcing baffle 5 and the retaining slope, forming the first waterproof sealing layer;

[0088] Step 4: De-energize the first electromagnet 602 and the fifth electromagnet 9021 to release the adsorption; de-energize the third electromagnet 505, and the elastic rope 11 pulls the slider 2011 backward along the slide groove 201, causing the sealing plate 6 to move away from the reinforcing baffle 5. When the slider 2011 slides to its maximum stroke, the fourth electromagnet 2012 is energized, adsorbing the slider 2011 to achieve the positioning of the sealing plate 6; open the solenoid valve of the fourth gas supply pipe 14, and gas fills the second airbag 8, causing it to expand and press against the hole wall;

[0089] Step 5: Start the two sets of grouting pumps 4. Grouting materials A and B enter the grouting head 2 through the conveying pipe 402 and the grouting pipe 202, and are then mixed and sprayed into the grouting hole after being injected through the grouting head 2.

[0090] Step Six: As the slurry is injected, some of it enters the second storage chamber 601, pushing the first sliding plug 6014 to compress the first spring 6011. When the second magnet 6013 and the second electromagnet 6012 are attracted, the compressed gas enters the sliding chamber 603 through the fifth gas supply pipe 604, pushing the second sliding plug 6031 downward, causing the scraper 13 to adhere tightly to the hole wall. The operator slowly pulls the grouting head 2 outward, while maintaining a stable grouting pressure. The scraper 13 moves with the grouting head 2, scraping away the mud, sand, and gravel deposited at the bottom of the hole to ensure that the slurry fills the bottom of the hole.

[0091] Step 7: After grouting is completed, the staff pulls the grouting head 2 backward, and the material stored in the second storage chamber 601 is squeezed out to fill the grouting gap left by the removal of the grouting head 2 in the sealing plate 6.

[0092] Step 8: After the grout has pre-set, open the pressure relief valve of the second airbag 8. After it contracts, completely pull the grouting head 2 out of the grouting hole. The first airbag 7 remains in the grouting hole with the reinforcing baffle 5 as a filling support.

[0093] In specific implementation, grouting material A consists of low-viscosity flexible asphalt W200, environmentally friendly rubber aromatic oil, rosin polyester polyol JC-380, wanenate PM200, dibutyltin disilicate, and additives; grouting material B is a curing agent, specifically TMR-2.

[0094] It should be noted that after the expanded material is mixed with the gel and expanded, the material will also be filled and expanded in the through hole 501. After expansion, it will be solidified and connected with the reinforcing baffle 5. The reinforcing baffle 5 can block the retaining slope at the far end of the grouting hole to prevent the retaining slope from collapsing and causing a large amount of soil to enter the grouting hole, which would affect subsequent grouting. On the other hand, it can seal the gap between the reinforcing baffle 5 and the retaining slope after the expanded material is sprayed out, effectively improving the overall strength and stability of subsequent grouting and reducing the problem of secondary leakage caused by the collapse of the retaining slope due to voids.

[0095] Example 3: Reference Figure 7 A seepage point sealing device for a water conveyance canal is basically the same as that in Embodiment 1. Furthermore, a third magnet 12 is fixedly connected to the connecting pipe 5041, and a fifth electromagnet 9021 is fixedly connected to the third gas conveying pipe 902. The third magnet 12 and the fifth electromagnet 9021 attract each other.

[0096] It should be noted that when the first electromagnet 602 is de-energized, causing the reinforcing baffle 5 to separate from the sealing plate 6, the fifth electromagnet 9021 is simultaneously de-energized, thereby ensuring that the sealing plate 6 can be stably pulled and slid by the elastic rope 11.

[0097] Reference Figure 7 In specific implementation, a sealing ring 901 is fixedly connected to the side wall of the plug 9. When the plug 9 is inserted into the connecting tube 5041, the sealing ring 901 abuts against the inner side wall of the connecting tube 5041.

[0098] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
