Description

Technical Field

[0001] This invention relates to the field of soft soil foundation treatment and drainage technology, and in particular to a drainage device for soft soil foundation treatment on highways and its usage method. Background Technology

[0002] According to my country's highway industry standards, soft soil foundations are defined as weak soil layers with low strength and high compressibility, often containing a certain amount of organic matter. Due to their low strength and large settlement, soft soil often poses significant risks to road engineering. Improper handling can greatly affect the construction and use of highways. In the construction of soft soil foundation treatment for highways, drainage pipe networks are usually inserted into the soft soil layer to improve the rapid drainage of water and prevent the foundation from being eroded by water.

[0003] For example, in the prior art, there is a gravity-based drainage consolidation system for soft soil foundations disclosed in CN114045812B. Although this consolidation system can improve the efficiency of water drainage in the soft soil layer, it still has certain limitations. For example, the drainage well lacks a structure to prevent the seepage holes and filter cartridges from clogging. During use, particles larger than the seepage holes in the soft soil layer are prone to clogging them, thereby reducing the efficiency of water entering the drainage well. Meanwhile, particles smaller than the seepage holes will enter with the groundwater and accumulate in the drainage well, causing the filter cartridges to become clogged. This makes it difficult to clean the impurities inside the drainage well and reduces the drainage efficiency.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a drainage device for treating soft soil foundations on highways and its usage method, to solve the aforementioned technical defects. First, a transmission structure drives the pumping pipe to rotate, which in turn drives the cleaning component to reciprocate within the seepage pipe and the crushing component to rotate rapidly within the suction hood. This achieves the discharge of some impurities and the crushing of impurities that cannot be discharged, thereby avoiding the problem of pumping pipe blockage and reduced drainage efficiency. Then, the reciprocating cleaning component, in conjunction with the unblocking component, ensures that it only unblocks the seepage holes during the upward movement and reduces the number of impurities entering through the unblocked seepage holes and located below the cleaning component during the downward movement, thus avoiding the problem of excessive impurity accumulation in the suction hood affecting the crushing efficiency.

[0016] A method of using a drainage device for treating soft soil foundations on highways includes the following steps:

[0017] Step 1: Combine multiple seepage pipes in a rectangular array to form a drainage network and insert it into the soft soil layer. Water in the soft soil layer enters the seepage pipes through the seepage holes and is pumped out through the pumping pipes.

[0018] Step 2: The pumping pipe is driven to rotate through the transmission structure. During the rotation of the pumping pipe, the movable plate is driven by the transmission groove on its outer side and moves back and forth in the seepage pipe in conjunction with the vertical rod. As the movable plate rises, it works with the unblocking structure to clear large particles or small particles that are blocking the seepage holes. After clearing, the small particles that have entered the seepage pipe through the seepage holes fall to the top of the movable plate.

[0019] Step 3: After the movable plate rises to the top of the seepage pipe, the support plate moves down under its own weight through the cooperation of the first abutment block on the vertical rod. During the descent of the movable plate, the guide block cannot force the movable column to move, thus avoiding the blockage of the seepage hole and reducing the amount of fine particles that fall into the bottom of the seepage pipe through the unblocking seepage hole. After the movable plate descends to the lowest point, the support plate is reset by the cooperation of the second abutment block on the vertical rod.

[0020] Step 4: During the rotation of the water pump pipe, the crushing component inside the water suction hood is driven to crush the impurities that cannot be discharged from the seepage pipe. After the movable plate rises to the top of the seepage pipe, the impurities on the top of the movable plate are cleaned by the flushing component and discharged from the fixed housing.

[0021] The beneficial effects of this invention are as follows:

[0022] (1) The present invention first uses a transmission structure in conjunction with a suction pipe to make the suction pipe discharge water from the seepage pipe while driving it to rotate, so that the movable plate in the cleaning component moves back and forth in the seepage pipe and discharges the impurities that fall on the top of the movable plate in the seepage pipe. After discharge, the top of the movable plate is rinsed with a flushing component to prevent the discharged impurities from returning to the seepage pipe with the cleaning component. During the upward movement of the movable plate, the guide block at its top, which is resisted by the fixed plate, can be used with the unblocking component to unblock the seepage holes, thereby preventing the accumulation of large or small impurities that block the seepage holes and thus reducing the efficiency of water discharge in the soft soil layer.

[0023] (2) The present invention also drives the water suction hood to rotate synchronously through the water suction pipe, thereby driving the crushing component to crush the fine part impurities that enter the water suction hood in multiple ways, reducing the size of the part of the impurities that cannot be discharged in the water seepage pipe, thereby avoiding the problem of blockage of the water suction pipe.

[0024] (3) When the movable plate in this invention rises to the top, the fixed plate contacts the abutting block at the top of the vertical rod, forcing the fixed plate to rotate. Under the weight of the support plate itself, the guide block and the fixed plate are automatically separated. This prevents the guide block from forcing the unblocking component to unblock the seepage hole during the descent of the movable plate, reducing the number of fine particles that enter through the unblocked seepage hole and are located below the movable plate. This avoids the accumulation of too many impurities in the water suction hood, which reduces the crushing efficiency of the crushing component and thus affects the drainage efficiency. In addition, when the movable plate descends to the bottom, the support plate contacts the abutting block at the bottom of the vertical rod, automatically resetting the guide block. This allows the unblocking component to unblock the seepage hole and discharge some impurities again during the descent of the movable plate. Attached Figure Description

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Example 1:

[0047] To address the problem of reduced drainage efficiency due to the lack of anti-clogging structures in existing technologies, the following solutions can be implemented:

[0048] Please see Figures 1-8 As shown, this embodiment of a drainage device for treating soft soil foundations on highways includes a base plate 1. A seepage pipe 11 is fixedly connected to the base plate 1. The top of the seepage pipe 11 extends through to the top of the base plate 1 for connection with the end of the fixed housing 3. Several seepage holes 12 are opened through the outer wall of the seepage pipe 11 for water in the soft soil layer to seep into the seepage pipe 11. Several unblocking components 2 are installed on the inner wall of the seepage pipe 11 for unblocking the seepage holes 12. The top of the base plate 1 is bolted to a fixed housing 3 sleeved on the outside of the seepage pipe 11. A pumping pipe 31 extending into the seepage pipe 11 is rotatably connected to the fixed housing 3. The top of the pumping pipe 31 is fixedly connected to a suction pipe 33 through a rotary joint 32. The free end of the pumping pipe 31 is connected to an external pump for use in conjunction with the pumping pipe 31 to discharge the water in the seepage pipe 11.

[0049] A transmission groove 34 is provided on the outer wall of the water-drawing pipe 31 inside the seepage pipe 11. The transmission groove 34 is composed of two threaded grooves with the same pitch and opposite directions of rotation, and the ends of the two threaded grooves are smoothly connected to each other. This is used to enable the water-drawing pipe 31 to drive the cleaning component 4 to reciprocate without changing the direction of rotation. The cleaning component 4 is installed on the outside of the water-drawing pipe 31 to drive the impurities inside the seepage pipe 11 and located at its top to be discharged. The cleaning component 4 cooperates with the transmission structure 5 installed on the base plate 1 through the transmission groove 34 to drive its reciprocating motion. The transmission structure 5 drives the water-drawing pipe 31 to rotate, thereby realizing the reciprocating motion of the cleaning component 4. The cleaning component 4 cooperates with the unblocking component 2. The reciprocating cleaning component 4, together with the unblocking component 2, performs unblocking treatment on the seepage hole 12. The bottom of the water-drawing pipe 31 is fixedly connected to the water-absorbing cover 35, and the water-absorbing cover 35 is equipped with a crushing component 6. The inside of the fixed housing 3 is equipped with a rinsing component 7 for cleaning the cleaning component 4.

[0050] The unblocking assembly 2 includes a vertical rod 21 and an unblocking structure 22. The top of the vertical rod 21 is fixedly connected to the top of the fixed housing 3. A groove 13 adapted to the corresponding vertical rod 21 is provided on the inner wall of the seepage pipe 11 for stable connection of the vertical rod 21 within the seepage pipe 11. An unblocking structure 22 is installed on the vertical rod 21 at the position corresponding to each seepage hole 12. The unblocking structure 22 includes a movable column 23, an unblocking rod 24, and a return spring 25. A movable column 23 is installed on one side of the vertical rod 21, and a spring groove is provided on the side of the vertical rod 21 away from the seepage pipe 11. The movable column 23 is slidably connected to the corresponding... The spring groove provides space for the cleaning component 4 to move when it abuts against the movable column 23. One end of the movable column 23 is fixedly connected to a cleaning rod 24 that is slidably connected to the vertical rod 21. When the movable column 23 moves, it drives the cleaning rod 24 to move, and through its extension into the seepage hole 12, it achieves the effect of unblocking the seepage hole 12. A reset spring 25 is sleeved on the outside of the cleaning rod 24. The two ends of the reset spring 25 are fixedly connected to the spring groove and the movable column 23 respectively, so as to achieve the reset effect after the movable column 23 moves. The free end of the cleaning rod 24 passes through the vertical rod 21 and extends into the corresponding seepage hole 12.

[0051] The cleaning component 4 includes a movable plate 41, a chute 42, a filter screen 43, a support plate 44, and a guide block 45. A movable plate 41, which is slidably connected to the inner wall of the seepage pipe 11, is threaded onto the outer wall of the pumping pipe 31. The movable plate 41 engages with a transmission groove 34 on the outer wall of the pumping pipe 31. A chute 42, which slidably connects to the corresponding vertical rod 21, is also provided on the outer wall of the movable plate 41. By cooperating with the vertical rod 21 through the chute 42, the movable plate 41 is prevented from rotating along with the pumping pipe 31, thus achieving a reciprocating motion effect. A through groove is provided on the movable plate 41 between adjacent chute 42s, and a filter screen 43 is fixedly installed within the through groove. 3. The filter screen 43 prevents the water in the seepage pipe 11 from being squeezed back into the soft soil layer through the seepage hole 12 during the downward movement of the movable plate 41. The top of the movable plate 41 is slidably connected to the vertical rod 21, and the top of the support plate 44 is equipped with a guide block 45. As the movable plate 41 rises, the guide block 45 on its support plate 44 contacts the end of the movable column 23 at the position of the seepage hole 12, compressing the reset spring 25 and driving the unblocking rod 24 to move. The end of the unblocking rod 24 extends out of the seepage hole 12, thereby clearing large particles or small particles that are blocked in the seepage hole 12.

[0052] The guide block 45 is slidably connected to the support plate 44. The guide block 45 has an elliptical structure, which makes it easy to force the movable column 23 to move. By sliding the guide block 45 to the support plate 44, the movable plate 41 can be lowered without the guide block 45 forcing the movable column 23 to move. The guide block 45 has symmetrical limit grooves 46 on both sides. The support plate 44 is equipped with limit blocks 47 that are slidably connected to the corresponding limit grooves 46. The limit grooves 46 and limit blocks 47 prevent the guide block 45 from separating from the support plate 44. The top of the movable plate 41 is fixedly connected to a fixed seat 48 on one side of each support plate 44. A fixed plate 49 is rotatably connected inside the fixed seat 48. The fixed plate 49 abuts against the guide block 45, so that the guide block 45 forces the movable column 23 to move.

[0053] A fixing hole 410 is provided on the side of the fixed plate 49 near the support plate 44. A fixing post 411 that matches the fixing hole 410 is fixedly connected to the support plate 44. The fixing hole 410 and the fixing post 411 cooperate to fix the position of the support plate 44, so as to prevent the support plate 44 from moving up and down during the upward movement of the movable plate 41, and to prevent the fixed plate 49 from hitting the guide block 45. A second return spring 412 connected to the fixed plate 49 is installed in the fixed seat 48. The two ends of the second return spring 412 are fixedly connected to the inner side wall of the fixed seat 48 and the fixed plate 49 respectively, thereby realizing the reset effect after the fixed plate 49 rotates.

[0054] On the vertical rod 21, at the top and bottom ends near the movable plate 41, abutment block 1 26 and abutment block 27 are fixedly connected respectively. After the movable plate 41 rises to the top of the seepage pipe 11, the fixed plate 49 on the movable plate 41 contacts the abutment block 1 26, forcing the fixed plate 49 to deflect and compress the reset spring 2 412. The fixing hole 410 on the fixed plate 49 separates from the fixing post 411 on the support plate 44. The support plate 44 moves down under its own weight, so that the fixed plate 49 no longer abuts against the guide block 45. After the movable plate 41 descends to the lowest point, the bottom of the support plate 44 contacts the abutment block 2 27 and pushes the support plate 44 up, forcing the fixed plate 49 to deflect again and compress the reset spring 2 412. The fixed plate 49 abuts against the guide block 45 again. The fixed plate 49 resets under the compression of the reset spring 2 412, completing the engagement of the fixing post 411 and the fixing hole 410, and fixing the position of the support plate 44.

[0055] The transmission structure 5 includes a motor 51, a drive wheel 52, a driven wheel 53, and a belt 54. The motor 51 is bolted to one side of the top of the base plate 1, and the drive wheel 52 is fixedly connected to the head of the conveying shaft of the motor 51. The driven wheel 53 is fixedly connected to the outer side of the fixed housing 3 on the outer wall of the water pumping pipe 31. The drive wheel 52 and the driven wheel 53 are connected by a belt 54 to realize the rotation of the water pumping pipe 31.

[0056] Example 2:

[0057] To address the issue of impurities accumulating inside the seepage pipe and causing blockages in the pumping pipe, the following solutions can be implemented:

[0058] Please see Figure 6 and Figure 11 As shown, in this embodiment, the pulverizing component 6 includes a second filter screen 61, a mounting plate 62, a transmission housing 63, a rotating shaft 64, a first bevel gear 65, a rotating tube 66, a second bevel gear 67, a first pulverizing blade 68, a transmission rod 69, a third bevel gear 610, a blade holder 611, and a second pulverizing blade 612. The second filter screen 61 and the mounting plate 62 are fixedly connected inside the water absorption hood 35, and the mounting plate 62 is located between the second filter screen 61 and the water suction pipe 31. The second filter screen 61 is used to block fine particulate impurities that enter the seepage pipe 11 and prevent them from entering the water suction pipe. Inside the pipe 31, a transmission housing 63 is fixedly connected to the bottom of the seepage pipe 11 for the installation of the rotating pipe 66. A rotating shaft 64 is rotatably connected to the mounting plate 62, which passes through the transmission housing 63. A bevel gear 65 is fixedly connected to the free end of the rotating shaft 64. A rotating pipe 66 is rotatably connected to the outer wall of the rotating shaft 64. One end of the rotating pipe 66 passes through the transmission housing 63 and is fixedly connected to a bevel gear 67. The rotating pipe 66 is rotatably connected to the transmission housing 63. Multiple crushing blades 68 are installed on the outer wall of the rotating pipe 66 inside the water absorption cover 35.

[0059] A transmission rod 69 is rotatably connected to one side of the transmission housing 63. One end of the transmission rod 69 is fixedly connected to a bevel gear 610 that meshes with bevel gear 65 and bevel gear 67. During the rotation of the water suction pipe 31, the rotating shaft 64 is driven to rotate. The rotating shaft 64 drives the rotating tube 66 to rotate rapidly through the meshing bevel gears 65, 610, and 67. The rotating tube 66 drives the crushing blade 68 and works with the filter screen 61 to crush the impurities accumulated in the water suction hood 35, reducing the size of the impurities that cannot be discharged from the seepage pipe 11, thereby avoiding the problem of blockage in the water suction pipe 31. The free end of the transmission rod 69 extends to the outside of the transmission housing 63 and is fixedly connected to a blade holder 611. Multiple crushing blades 612 are installed on the outer wall of the blade holder 611. During the rotation of the bevel gear 610, the crushing blades 612 drive the transmission rod 69 to perform preliminary crushing of the impurities. Combined with the secondary crushing by the crushing blade 68, the impurities become even finer.

[0060] Example 3:

[0061] To address the issue that impurities discharged from the cleaning components can easily flow back into the seepage pipe, the following solutions can be implemented:

[0062] Please see Figure 9 and Figure 10As shown, in this embodiment, the rinsing assembly 7 includes a rinsing nozzle 71, an annular pipe 72, a telescopic pipe 73, a water inlet pipe 74, and a waste discharge pipe 75. A rinsing nozzle 71 is installed between two adjacent vertical rods 21 inside the fixed housing 3, and an annular pipe 72 is installed on the top of the fixed housing 3. A telescopic pipe 73 is fixedly connected between each rinsing nozzle 71 and the annular pipe 72. A water inlet pipe 74 is fixedly connected to the annular pipe 72, and the free end of the water inlet pipe 74 is connected to an external water pump. Cleaning water is injected into the annular pipe 72 through the external water pump and the water inlet pipe 74. The water in the annular pipe 72 passes through the telescopic pipe 73 and is sprayed out through the rinsing nozzle 71 to rinse the impurities on the top of the movable plate 41. A waste discharge pipe 75 is fixedly connected to one side of the bottom of the fixed housing 3. The rinsed impurities fall to the bottom of the fixed housing 3 and are discharged from the waste discharge pipe 75.

[0063] A mounting base 76 is fixedly connected to the top of the fixed housing 3, corresponding to the position of each flushing nozzle 71. A swing seat 77 for mounting the flushing nozzle 71 is rotatably connected to the mounting base 76 via a rotating pin, enabling the flushing nozzle 71 to swing back and forth, thereby increasing the flushing area and improving the flushing effect. A slide rod 78 is slidably connected to the side of the mounting base 76 near the water pipe 31. Pins 79 are symmetrically fixedly connected to both sides of the slide rod 78 within the mounting base 76. The swing seat 77 has a slot 7 that slidably connects to the corresponding pin 79. 10. A rotating disc 36 is fixedly connected to the outer wall of the water pump pipe 31, which abuts against the ends of each slide rod 78. A return spring 311 is fixedly connected between the free end of the slide rod 78 and the inner wall of the mounting base 76. During the rotation of the water pump pipe 31, the rotating disc 36 is driven to rotate. The rotating disc 36, in conjunction with the return spring 311, pushes the slide rod 78 to reciprocate. The slide rod 78 drives the swing seat 77 to swing back and forth through the pin 79 and the slot 710, continuously changing the spray angle of the flushing nozzle 71 and improving the flushing efficiency.

[0064] Example 4:

[0065] Please see Figures 1-11 As shown, a method of using a drainage device for treating soft soil foundations on highways includes the following steps:

[0066] Step 1: Combine multiple seepage pipes 11 in a rectangular array to form a drainage network and insert it into the soft soil layer. Connect the free end of the suction pipe 33 to an external water pump and the free end of the inlet pipe 74 to an external water pump. Water in the soft soil layer enters the seepage pipe 11 through the seepage hole 12. The water in the seepage pipe 11 is pumped out by the external water pump in conjunction with the pumping pipe 31.

[0067] Step 2: Start the motor 51, which, together with the active transmission wheel 52, the driven transmission wheel 53 and the belt 54, drives the pumping pipe 31 to rotate. During the rotation of the pumping pipe 31, the transmission groove 34 on its outer side drives the movable plate 41 and the vertical rod 21 to reciprocate in the seepage pipe 11. As the movable plate 41 rises, the guide block 45 on its support plate 44, under the action of the fixed plate 49, contacts the end of the movable column 23 at the corresponding seepage hole 12. While compressing the reset spring 25, it drives the unblocking rod 24 to move. The end of the unblocking rod 24 extends out of the seepage hole 12 and clears the large particles or small particles that are blocking the seepage hole 12, improving the efficiency of water entering the seepage pipe 11 from the soft soil layer. The fine particles that enter from the cleared seepage hole 12 fall to the top of the movable plate 41. After the guide block 45 separates from the movable column 23, the unblocking rod 24 is reset under the compression of the reset spring 25.

[0068] Step 3: After the movable plate 41 rises to the top of the seepage pipe 11, the fixed plate 49 on the movable plate 41 contacts the abutment block 26, forcing the fixed plate 49 to deflect and compress the reset spring 412. The fixed hole 410 on the fixed plate 49 separates from the fixed column 411 on the support plate 44. The support plate 44 moves down under its own weight, so that during the descent of the movable plate 41, the fixed plate 49 is reset under the compression of the reset spring 412. The fixed plate 49 no longer abuts against the guide block 45. The guide block 45 cannot force the movable column 23 to move and cannot clear the blockage of the seepage hole 12. This prevents small particles of impurities from falling into the bottom of the seepage pipe 11 through the clear seepage hole 12 during the descent of the movable plate 41, causing blockage of the pumping pipe 31.

[0069] Step 4: After the movable plate 41 descends to its lowest point, the bottom of the support plate 44 contacts the second abutment block 27 and pushes the support plate 44 upward. At the same time, it forces the fixed plate 49 to deflect and compress the second return spring 412. The fixed plate 49 then abuts against the guide block 45 again. Under the compression of the second return spring 412, the fixed plate 49 is reset, completing the engagement of the fixed column 411 and the fixed hole 410, thus limiting the downward movement of the support plate 44 during the upward movement of the movable plate 41.

[0070] Step 5: During the rotation of the water suction pipe 31, the rotating shaft 64 is driven to rotate. The rotating shaft 64 drives the rotating pipe 66 to rotate rapidly through the meshing bevel gear 1 65, bevel gear 3 610 and bevel gear 2 67. The rotating pipe 66 drives the crushing blade 1 68 and works with the filter screen 2 61 to crush the impurities accumulated in the water suction hood 35. At the same time, during the rotation of the bevel gear 3 610, the crushing blade 2 612 is driven through the transmission rod 69 to perform preliminary crushing of the impurities. Combined with the secondary crushing of the crushing blade 1 68, the impurities become smaller, thereby preventing the water suction pipe 31 from becoming blocked.

[0071] Step Six: After the movable plate 41 rises to the top of the seepage pipe 11, it moves the impurities that have fallen on top of it out of the seepage pipe 11. At this time, the external water pump, in conjunction with the water inlet pipe 74, injects cleaning water into the annular pipe 72. The water in the annular pipe 72 is sprayed out through the telescopic pipe 73 and the flushing nozzle 71 to wash the impurities on the top of the movable plate 41. The washed-off impurities fall to the bottom of the fixed housing 3 and are discharged from the waste discharge pipe 75. During the rotation of the water pump 31, the rotating disc 36 is driven to rotate. The rotating disc 36, in conjunction with the return spring 711, pushes the slide rod 78 to reciprocate. The slide rod 78, through the pin 79 and the slot 710, drives the swing seat 77 to swing back and forth, continuously changing the spray angle of the flushing nozzle 71 and improving the flushing efficiency.

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.

4. A method of using a drainage device for treating soft soil foundations on highways, as described in claim 3, characterized in that... Includes the following steps: Step 1: Combine multiple seepage pipes (11) in a rectangular array to form a drainage network and insert them into the soft soil layer. Water in the soft soil layer enters the seepage pipes (11) through the seepage holes (12) and is pumped out through the pumping pipes (31). Step 2: Drive the pumping pipe (31) to rotate through the transmission structure (5). During the rotation of the pumping pipe (31), the movable plate (41) is driven by the transmission groove (34) on its outer side and moves back and forth in the seepage pipe (11) in conjunction with the vertical rod (21). As the movable plate (41) rises, it works with the unblocking structure (22) to clear the large particles or small particles that are blocked in the seepage hole (12).
