Description

Technical Field

[0001] This invention relates to the field of slope drainage technology, specifically a slope drainage method utilizing horizontal directional drilling. Background Technology

[0002] Slopes are typically composed of materials such as soil and rock. In engineering, slopes refer to artificially excavated or constructed slopes, such as highway slopes, dam slopes, and earthwork slopes. The stability of slopes is crucial to the safety of engineering projects.

[0003] Unstable slopes are prone to collapse, primarily because excess water within the slope is not drained in time. Therefore, slope drainage can improve slope stability, reduce the adverse effects of water on the slope, and protect the slope soil and structures.

[0004] When draining deep sections of a slope, drilling and the installation of a deep drainage system are necessary to guide groundwater out from the interior, thereby reducing slope stability issues caused by groundwater pressure and rising groundwater levels. Horizontal directional drilling can be used to create straight holes at a certain angle. After drilling, it is easy to lay pipes to remove excess water from the interior.

[0005] The existing technology has the following main problems when carrying out slope drainage work: 1. When draining the deep part of the slope, the borehole usually has a certain degree of inclination. Therefore, when inserting the pipe into the borehole, it is necessary to ensure that the pipe is inserted into the borehole at a certain angle. It is generally difficult to find the right angle and ensure that the pipe is always inserted at a certain angle during the insertion process, which makes the construction process inconvenient.

[0006] 2. Since the pipes inserted into the deep slope have a certain length, it is difficult to ensure that the required pipe section enters the borehole stably and continuously. Once an insertion deviation occurs during the pipe insertion process, it is easy to damage the inner wall of the borehole, causing internal collapse, which affects the smooth insertion of the pipe and the efficiency of pipe laying.

[0007] Therefore, in order to solve the problems of difficulty in accurately determining the inclination angle during pipeline laying and instability and easy deviation during pipe insertion, this invention provides a slope drainage method using horizontal directional drilling. Summary of the Invention

[0011] S2. Drilling construction: At the designated location of the required drainage slope, use a horizontal directional drilling tool to drill in the designated direction at the designated angle. After reaching the designated drilling depth, remove the horizontal directional drilling tool and then fix a guide steel pipe in the middle of the hole.

[0012] S3. Pipeline laying: Based on the pre-determined drilling data, the mobile machine moves to the corresponding position, then adjusts the tilt angle through the tilt angle adjustment unit, and then adjusts the appropriate docking height through the height adjustment unit.

[0024] In summary, the present invention has at least one of the following beneficial technical effects:

[0025] 1. This invention provides a slope drainage method using horizontal directional drilling. The included tilt angle adjustment unit, through a lifting section, rotates the mounting plate around the installation support at a certain angle to achieve the desired tilt angle. This angle can be set according to the drilling angle to control the flexible adjustment of the lifting section. Ultimately, the mounting plate is stabilized at a certain tilt angle to facilitate subsequent stable PVC pipe installation. The included auxiliary pipe insertion unit first centers and limits the PVC pipe, then clamps it securely in the center. This ensures the PVC pipe can only follow the clamping section in a stable linear feed motion when the hydraulic pusher pushes the clamping section, guaranteeing continuous and smooth pipe insertion. Simultaneously, the highly automated coordination of the moving unit, height adjustment unit, tilt angle adjustment unit, and auxiliary pipe insertion unit in this device ensures smooth drilling and pipe insertion, improving pipeline laying efficiency.

[0026] 2. The central part of the present invention drives the cylindrical sliding pin to move relative to each other through the rotation of the gear disk, so that the sliding push block can slide together on the fixed ring towards the center of the fixed ring, thereby achieving stable centering and limiting of the PVC pipe. This ensures that the PVC pipe can make linear feeding motion along the axis of the fixed ring during the subsequent insertion process. The ball bearings make the PVC pipe move linearly along the central axis of the fixed ring both stable and easy.

[0027] 3. The clamping part of the present invention, together with the concave and convex rubber pads on the opposite surface of the clamp, can increase the friction between the clamp and the PVC pipe, ensuring that the sliding installation part will not slip when it moves to the right, that is, pushes the PVC pipe into the drill hole, thus ensuring stable and continuous pipe insertion.

[0044] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0045] Please see Figure 1 and Figure 2 A slope drainage method utilizing horizontal directional drilling employs a slope drainage device comprising: a mobile body 1, a height adjustment unit 2, an inclination adjustment unit 3, and an auxiliary pipe insertion unit 4. The mobile body 1 is equipped with the height adjustment unit 2, the height adjustment unit 2 with the inclination adjustment unit 3, and the inclination adjustment unit 3 with the auxiliary pipe insertion unit 4. The specific method for slope drainage using this horizontal directional drilling device is as follows:

[0046] S1. Survey and Design: Determine the characteristics, soil conditions and groundwater level of the required drainage slope through geological survey, and then determine the location, diameter, and spacing of boreholes, as well as the size and route of PVC pipelines based on the geological survey.

[0047] S2. Drilling construction: At the designated location of the required drainage slope, use a horizontal directional drilling tool to drill in the designated direction at the designated angle. After reaching the designated drilling depth, remove the horizontal directional drilling tool and then fix a guide steel pipe in the middle of the hole.

[0048] S3. Pipeline laying: Based on the pre-measured drilling data, the mobile body 1 reaches the corresponding position, then the tilt angle is adjusted by the tilt angle adjustment unit 3, and the appropriate docking height is adjusted by the height adjustment unit 2. Finally, under the guidance of the guide steel pipe, the PVC pipeline is stably inserted into the borehole by the auxiliary pipe insertion unit 4.

[0049] S4. Filling with grouting material: After the PVC pipeline is laid, fill the drilled holes with appropriate grouting material to stabilize the pipeline position.

[0050] S5. Drainage test: Conduct a drainage test to ensure that the drainage system is working properly.

[0051] Please see Figure 3 , Figure 4 and Figure 5 The tilt adjustment unit 3 includes a mounting support 31, a positioning connector 32, a mounting plate 33, a clearance groove 34, a sliding connector 35, an L-shaped load plate 36, and a lifting part 37. The mounting support 31 is symmetrically fixedly installed on the upper left side of the height adjustment unit 2. The mounting support 31 is hinged to each of the mounting supports 31. The mounting plate 33 is fixedly installed on the upper end of the positioning connector 32. The clearance groove 34 is opened on the lower right side of the mounting plate 33. The sliding connector 35 is slidably arranged in the clearance groove 34. The L-shaped load plate 36 is fixedly installed on the height adjustment unit 2. The lifting part 37 is provided on the L-shaped load plate 36. The lifting part 37 is hinged to the sliding connector 35.

[0052] Please see Figure 2The auxiliary insertion unit 4 includes a centering part 41, a centering part 42, a fixed rail 43, a clamping part 44, a mounting base 45, and a hydraulic push rod 46. The centering part 41 is fixedly installed on the upper right side of the mounting plate 33. The centering part 42 is fixedly installed on the upper end of the mounting plate 33 and to the left of the centering part 41. The fixed rail 43 is fixedly installed on the upper end of the mounting plate 33 and to the left of the centering part 42. The clamping part 44 is slidably arranged on the fixed rail 43. The mounting base 45 is fixedly installed on the upper end of the mounting plate 33 and to the left of the fixed rail 43. The hydraulic push rod 46 is fixedly installed on the mounting base 45. The right end of the telescopic rod of the hydraulic push rod 46 is fixedly connected to the clamping part 44.

[0053] Based on the data obtained from the survey and design and drilling construction steps, this device is operated to complete the insertion of PVC pipes. First, the moving body 1 is moved to the construction position. Then, the PVC pipe to be inserted into the borehole is pre-clamped by the centering part 42 and the clamping part 44. The centering part 42 can center and limit the PVC pipe, so that the PVC pipe can only follow the clamping part 44 in a linear feed motion when the hydraulic push rod 46 pushes the clamping part 44. Then, the lifting part 37 pushes the sliding connector 35 to move upward to lift the mounting plate 33. The mounting plate 33 will rotate counterclockwise around the mounting support 31 by a certain angle. During this process, the sliding connector 35 will slide in the allowance groove 34 to compensate for displacement. When the mounting plate 33 rotates to the borehole inclination angle, the lifting part 33 will be lifted. The lifting unit 37 stops, and the height is adjusted by the height adjustment unit 2 so that the centering unit 41 can be aligned with the center of the guide steel pipe. During this process, when the centering unit 41 is aligned with the guide steel pipe, the operation of each unit of the device can make appropriate compensation adjustments until the center line of the centering unit 41 and the axis of the guide steel pipe are on the same horizontal line. Then, the hydraulic push rod 46 pushes the clamping unit 44 to move to the right. At this time, the clamping unit 44 will insert the PVC pipe into the borehole along the guide steel pipe. When the clamping unit 44 is pushed to the rightmost side of the fixed track 43, the clamping unit 44 will release the PVC pipe and quickly return to its original position under the leftward drive of the hydraulic push rod 46. Then the PVC pipe is clamped again, and the pushing work is repeated. This process is repeated until the PVC pipe is stably inserted into the borehole.

[0054] Please see Figure 3 , Figure 4 and Figure 5The lifting part 37 includes a fixed sliding sleeve 371, a sliding rack 372, a second mounting support 373, a second motor 374, a drive pulley 375, a positioning mounting part 376, a drive gear 377, a driven pulley 378, and a conveyor belt 379. The fixed sliding sleeve 371 is fixedly installed on the upper end of the horizontal plate of the L-shaped carrying plate 36. The sliding rack 372 is connected to the fixed sliding sleeve 371 in a sliding fit. The upper end of the sliding rack 372 is fixedly installed with a mounting support. Support 2 373 is hinged to sliding connector 35. A motor 2 374 is fixedly mounted on the upper horizontal plate of the L-shaped carrying plate 36, located in front of fixed sleeve 371, via a motor mount. The output shaft of motor 2 374 is fixedly connected to drive pulley 375. A positioning mounting piece 376 is fixedly mounted on the right end of the vertical plate of the L-shaped carrying plate 36, located in front of fixed sleeve 371. A drive gear 377 is rotatably connected to the positioning mounting piece 376. The right end of the drive gear 377 is fixedly connected to the driven pulley 378. The drive pulley 375 and the driven pulley 378 are connected by a transmission belt 379. The drive gear 377 meshes with the sliding rack 372. The drive pulley 375 is driven to rotate by the rotation of the second motor 374. The drive pulley 375 transmits the rotational power to the driven pulley 378 through the transmission belt 379. The driven pulley 378 drives the drive gear 377 to rotate synchronously, so as to drive the sliding rack 372 to rise steadily on the fixed sliding sleeve 371. Finally, the mounting plate 33 can rotate counterclockwise around the mounting support 31. When it rotates to the specified tilt angle, the second motor 374 stops rotating. At this time, the mounting plate 33 is in an inclined position consistent with the drilling angle. Similarly, the reverse rotation of the second motor 374 can make the sliding rack 372 move down, so that the mounting plate 33 can rotate clockwise to adjust the tilt angle, and finally return to a horizontal state.

[0055] Please see Figure 6 , Figure 7 and Figure 8The central part 42 includes a fixed base 421, a fixed ring 422, a sliding push block 423, a cylindrical sliding pin 424, a ball bearing 425, a gear disk 426, an arc-shaped through hole 427, a mating limiting member 428, and a drive assembly 429. A fixed base 421 is fixedly installed on the upper end of the mounting plate 33, located to the left of the fixed center part 41. A fixed ring 422 is fixedly installed on the upper end of the fixed base 421. Sliding push blocks 423 are evenly slidably arranged on both the left and right end faces of the fixed ring 422. Cylindrical sliding pins 424 are fixedly installed on each sliding push block 423. A ball bearing 425 is rolled on the end of the sliding push block 423 pointing towards the center of the fixed ring 422. A gear disk 426 is symmetrically rotatably connected to the front and rear ends of the fixed ring 422. Arc-shaped through holes 427 are evenly opened on each gear disk 426 along the circumference. The cylindrical sliding pins 424 pass through the arc-shaped through holes 427 and are aligned with the arc-shaped through holes. The through holes 427 slide together. The outer circumferential end of the fixed ring 422 is uniformly fixed with matching limiting parts 428. The upper end of the mounting plate 33 and the rear side of the fixed base 421 are fixedly installed with a drive group 429. The drive group 429 meshes with the gear disk 426 for transmission. When the PVC pipe is inserted into the fixed ring 422, the drive group 429 provides rotational power to the gear disk 426. During the rotation, the gear disk 426 pushes the corresponding cylindrical sliding pin 424 to move relative to each other through the arc-shaped through holes 427, so that the sliding push block 423 can slide together towards the center of the fixed ring 422 to achieve the centering and limiting of the PVC pipe. The reverse rotation of the gear disk 426 can release the PVC pipe. The ball bearings 425 make the PVC pipe move stably and easily when it moves linearly along the central axis of the fixed ring 422.

[0056] Please see Figure 7 , Figure 8 and Figure 9 The drive assembly 429 includes an L-shaped mounting platform 4291, a linkage shaft 4292, a meshing gear 4293, and a motor 4294. The L-shaped mounting platform 4291 is fixedly mounted on the upper end of the mounting plate 33 and located behind the fixed base 421. The linkage shaft 4292 is rotatably connected to the vertical platform of the L-shaped mounting platform 4291. The meshing gears 4293 are symmetrically fixedly mounted on the linkage shaft 4292, and mesh with corresponding gear discs 426. A motor 4294 is fixedly mounted on the upper part of the platform 1 via a motor mount. The output shaft of the motor 4294 is fixedly connected to the linkage shaft 4292. The rotation of the motor 4294 drives the linkage shaft 4292 to rotate, which in turn drives two mating gears 4293 to rotate synchronously in the same direction. Ultimately, this drives the opposing gear discs 426 to rotate synchronously in the same direction, thereby enabling the sliding push block 423 to move concentrically closer or further away, thus achieving the centered clamping or loosening of the PVC pipe.

[0057] Please see Figure 10 , Figure 11 and Figure 12 The clamping part 44 includes a sliding mounting part 441, a bidirectional threaded rod 442, a motor 443, a sliding support block 444, a mating fixture 445, and a concave-convex rubber pad 446. The sliding mounting part 441 is slidably mounted on the fixed track 43, and the bidirectional threaded rod 442 is rotatably connected to the sliding mounting part 441. The motor 443 is fixedly mounted at the front end of the fixed track 43, and the output shaft of the motor 443 is fixedly connected to the bidirectional threaded rod 442. The bidirectional threaded rod 442 is symmetrically threaded with the sliding support block 444, and the sliding support block 444 is slidably engaged with the sliding mounting part 441. The upper end of each sliding support block 444 is fixedly mounted with a mating fixture 445. Each of the mating clamps 445 has a raised rubber pad 446 on its opposite end face. The left end of the sliding mounting part 441 is fixedly connected to the telescopic rod of the hydraulic push rod 46. Initially, the mating clamps 445 are far apart. After the PVC pipe is centered and aligned by the centering part 42, the motor 443 drives the bidirectional threaded rod 442 to rotate, so that the mating clamps 445 move closer to each other and finally clamp the PVC pipe in the center. The raised rubber pads 446 can increase the friction between the PVC pipe and the sliding mounting part 441, ensuring that the PVC pipe will not slip when the sliding mounting part 441 moves to the right and pushes the PVC pipe into the borehole, thus ensuring stable and continuous pipe insertion.

[0058] Please see Figure 1 and Figure 3 The centering part 41 includes a placement base 411, an electric push rod 412, and a laser positioning device 413. The placement base 411 is fixedly installed on the upper right side of the mounting plate 33. The electric push rod 412 is fixedly installed on the mounting plate 33 and below the placement base 411. The telescopic rod of the electric push rod 412 passes through the placement base 411 and is fixedly installed with the laser positioning device 413. Initially, the laser positioning device 413 is at its highest position with the support of the electric push rod 412, that is, the laser beam of the laser positioning device 413 is aligned with the central axis of the fixed ring 422 (clamping part 4). 4) The center) is on the same horizontal line; after the tilt angle of the mounting plate 33 is adjusted, the height adjustment unit 2 cooperates with the moving body 1, and the laser ranging positioning of the laser positioning instrument 413 is used to find the center axis of the guide steel pipe (i.e., the drilling center). During the debugging process, each unit can be controlled to make certain coordination adjustments, so that the center line of the laser beam of the laser positioning instrument 413 coincides with the center axis of the guide steel pipe; finally, the laser positioning instrument 413 is lowered and placed on the placement base 411 by the electric push rod 412 to ensure that it does not affect the insertion work of the PVC pipe.

[0059] Please see Figure 2 and Figure 3The height adjustment unit 2 includes a loading groove 21, a mating groove 22, a threaded rod 23, a central slider 24, a connecting push rod 25, an opening and closing part 26, a load-bearing plate 27, and a motor 28. The moving body 1 is provided with a loading groove 21. A mating groove 22 is provided at the bottom of the loading groove 21. A threaded rod 23 is rotatably connected to the mating groove 22. A central slider 24 is threadedly connected to the threaded rod 23, and the central slider 24 slides within the mating groove 22. A connecting push rod 25 is fixedly installed on the central slider 24. An opening and closing part 26 is provided at the bottom of the loading groove 21, and the opening and closing part 26 is fixedly connected to the connecting push rod 25. A load-bearing plate 27 is provided at the upper end of the opening and closing part 26. The upper left side of the load-bearing plate 27... The front and rear are symmetrically fixed with mounting supports 31. An L-shaped load plate 36 is fixedly installed at the middle of the right end of the load-bearing plate 27. A motor 28 is fixedly installed at the middle of the left end of the moving body 1 through a motor mount. The output shaft of the motor 28 is fixedly connected to the threaded rod 23. The rotation of the motor 28 drives the threaded rod 23 to rotate forward or backward, which ultimately causes the central slider 24 to move to the left or right. When the central slider 24 moves to the right, it can drive the connecting push rod 25 to act on the opening and closing part 26, so that the load-bearing plate 27 rises under the support of the opening and closing part 26. When the central slider 24 moves to the left, it can drive the connecting push rod 25 to act on the opening and closing part 26, so that the load-bearing plate 27 moves downward with the opening and closing part 26 for adjustment.

[0060] Please see Figure 2 , Figure 3 and Figure 4The opening and closing part 26 includes a limiting slide rail 261, a sliding support 262, a connecting support plate 263, a fixed support 264, a connecting support plate 265, a limiting slide rail 266, a sliding support 267, and a fixed support 268. A limiting slide rail 261 is symmetrically fixedly installed on the left side of the bottom of the loading groove 21. A sliding support 262 is slidably mounted on each limiting slide rail 261, and a connecting support plate 263 is hinged to each sliding support 262. The sliding supports 262 are fixedly connected to each other by a connecting push rod 25. A fixed support 264 is fixedly installed at the bottom of the loading groove 21 and to the right of the limiting slide rail 261. A connecting support plate 265 is hinged to each fixed support 264. On the same side... The first connecting support plate 263 and the second connecting support plate 265 are hinged together.

The second fixed support 268 is fixedly installed on the lower end of the load-bearing plate 27 and on the right side of the second limiting slide rail 266. The second fixed support 268 is hinged to the first connecting support plate 263. When the connecting push rod 25 pushes the first sliding support 262 to the right to move on the first limiting slide rail 261, the first connecting support plate 263 and the second connecting support plate 265 jointly support the load-bearing plate 27 to move upward, realizing the height adjustment; conversely, the height decreases.

[0061] The working principle of this invention is as follows: First, the moving body 1 is moved to the construction position. Then, the PVC pipe to be inserted into the borehole is pre-installed and clamped by the centering part 42 and the clamping part 44. The centering part 42 can center and limit the PVC pipe, so that the PVC pipe can only follow the clamping part 44 in a straight line when the hydraulic push rod 46 pushes the clamping part 44. Then, the lifting part 37 pushes the sliding connector 35 upward to lift the mounting plate 33. The mounting plate 33 will rotate counterclockwise around the mounting support 31 by a certain angle. During this process, the sliding connector 35 will slide in the allowance groove 34 to compensate for displacement. When the mounting plate 33 rotates to the borehole inclination angle, the lifting part 37 stops. Then, the height adjustment unit... 2. Adjust the height so that the centering part 41 can be aligned with the center of the guide steel pipe. During this process, when the centering part 41 is aligned with the guide steel pipe, the entire unit of the device can be operated to make appropriate compensation adjustments until the center line of the centering part 41 and the axis of the guide steel pipe are on the same horizontal line. Then, the clamping part 44 is pushed to the right by the hydraulic push rod 46. At this time, the clamping part 44 will insert the PVC pipe into the borehole along the position of the guide steel pipe. When the clamping part 44 is pushed to the rightmost side of the fixed track 43, the clamping part 44 will release the PVC pipe and quickly return to its original position under the leftward drive of the hydraulic push rod 46. Then, the PVC pipe is clamped again and the pushing work is repeated until the PVC pipe is stably inserted into the borehole.
