Description

Technical Field

[0001] This invention relates to the field of drilling rig support technology, specifically to a wellbore wall positioning rock drilling rig and construction method. Background Technology

[0002] Installing shaft equipment and platforms within vertical and inclined shafts requires openings in the shaft wall for work and installing embedded parts. Since the shaft wall cannot be damaged and the opening area needs to be controlled, methods such as blasting are unsuitable. Currently, water-cooled drills are commonly used to drill holes within the opening area. This method of stacking boreholes to remove the foundation pit is suitable for complex working environments such as narrow spaces, high altitudes, and areas exposed to water within the shaft.

[0003] However, water-cooled drills are quite heavy, requiring manual support and maintenance of the rig throughout the process. This necessitates slowing down the drilling speed, significantly increasing the time required for single-hole construction and resulting in low overall efficiency. Furthermore, prolonged operation can lead to unstable manual gripping, causing the rig to shake, tip over, or even slip, which could easily injure operators or collide with surrounding equipment. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a wellbore wall positioning rock drilling rig and construction method.

[0005] The technical solution adopted by this invention to solve its technical problem is: A wellbore wall positioning rock drilling rig and construction method include a support assembly. The support assembly provides precise drilling guidance and a stable drilling environment for the water-cooled drill. The support assembly includes a guide component and two support components. The guide component ensures that the water-cooled drill can drill along a set route. The support components stabilize and adjust the drilling posture of the water-cooled drill. The guide component includes a guide rail platform with a support slide plate slidably connected to it. Two side pressure plates are symmetrically slidably connected to the support slide plate. Each of the two side pressure plates has an upper pressure plate at its top and a pressure rod threaded to the top surface of each of the two side pressure plates. The support components include two upper legs symmetrically arranged at the bottom of the guide rail platform. Each of the two upper legs has a lower leg slidably connected to its bottom, and an extension plate is slidably connected to both lower legs.

[0006] Furthermore, the guide component also includes a threaded rod, which is threadedly connected to the bottom of the support slide plate. Both ends of the threaded rod are rotatably connected to the lower surface of the guide rail. An electric cylinder is fixedly connected to the lower surface of the guide rail. The electric cylinder includes a fixed end and an output shaft. The output shaft end of the electric cylinder is fixedly connected to the threaded rod. A bellows is sleeved on the threaded rod and is fixedly connected to the support slide plate. Both ends of the bellows are fixedly connected to the guide rail. Multiple guide rods are fixedly connected in a linear array inside the support slide plate. Both side pressure plates are slidably connected to the guide rods. Each guide rod is fitted with a tension spring. Both ends of the tension spring are fixedly connected to the side of the two side pressure plates that are close to each other. Two guide rods are symmetrically fixedly connected to the top of each of the two side pressure plates. The two upper pressure plates are slidably connected to the two adjacent guide rods. Each guide rod is fitted with a tension spring. Both ends of the tension spring are fixedly connected to the top surface of the side pressure plate and the lower surface of the upper pressure plate.

[0007] Furthermore, the support component also includes four closely spaced toothed discs, arranged in pairs. Two discs in the same pair are symmetrically rotatably connected to the top of the upper support leg. The toothed discs are fixedly connected to the guide rail. Two torsion springs are symmetrically arranged on the top of each of the two upper support legs, with their ends fixedly connected to the upper support leg and the adjacent toothed disc, respectively. A tension spring (type 3) is installed inside each of the two upper support legs, with its ends fixedly connected to the top of the inner wall of the upper support leg and the top of the lower support leg, respectively. Multiple slots (type 1) are arranged in a vertical straight line on each of the two lower support legs. A crossbar is fixedly connected between the two sides of the crossbar. Two guide rods three are symmetrically fixedly connected to the crossbar. Each guide rod three is fitted with a tension spring four. A connecting rod is slidably connected to the two guide rods three. Each end of the connecting rod is fixedly connected with an insert rod one. A wedge block is slidably connected to the bottom of the crossbar. Each of the two lower support legs is fixedly connected to a caster wheel. Each of the two lower support legs has two slots two. An insert rod two is inserted into the top of the extension plate. Each end of the insert rod two is fitted with a tension spring five. The two ends of the tension spring five are fixedly connected to the extension plate and the insert rod two, respectively.

[0008] Furthermore, the side pressure plates are L-shaped, and the side of the two side pressure plates that are close to each other is made of frosted rubber anti-slip surface. The two upper pressure plates are staggered, and the lower surface of the upper pressure plates is made of frosted rubber anti-slip surface.

[0009] Furthermore, the pressure bar and the supporting slide plate are pressed together, and the top surface of the upper pressure plate is provided with a handle for easy operation by the user.

[0010] Furthermore, the top of the first insertion rod is engaged with the fine-toothed disc, the bottom of the first insertion rod is engaged with the first slot, the second insertion rod is engaged with the second slot, the top of the wedge is set as an inclined surface, the wedge is engaged with the connecting rod, and the bottom surface of the extension plate is set as a non-slip surface with a frosted finish.

[0011] A method for constructing a wellbore wall-positioning rock drilling rig includes the following steps: Step 1: Installing the positioning water drill: The user holds the handle of the upper pressure plate and pulls it to the sides and upwards to separate the two upper pressure plates and the two side pressure plates, causing the tension springs one and two to deform elastically, forming a rectangular gap with an opening at the top. Then, the water drill is placed into the gap and the upper pressure plate is released. Under the action of elasticity, the side pressure plates and the upper pressure plates hug and clamp the water drill. Finally, the pressure rod is tightened to press and cooperate with the support slide plate to lock the clamping state.

[0012] Step 2: Moving and coarsely adjusting the equipment position: Push the guide rail table and use the casters to move the whole machine to the construction area, so that the water drill bit is aligned with the vicinity of the hole to be drilled.

[0013] Further, step three: fine-tuning the equipment posture and fixing: push the wedge block limit linkage upward to unlock the insertion of the pair of fine-tooth discs of the insertion rod into slot one. Press the guide rail table as needed to adjust the height off the ground, or rotate the guide rail table to adjust the tilt angle. After adjustment, move the wedge block down to reset insertion rod one, lock the height and angle, then pull insertion rod two to move the extension plate down to contact the ground and fix it. Lock the casters to complete the stabilization of the whole machine.

[0014] Step 4: Start the drilling machine to carry out drilling: Drive the electric cylinder to rotate the threaded rod, so that the support plate slides along the guide rail axially, and simultaneously drive the water drill to move to the position to be drilled. At the same time, start the water drill and complete the drilling construction under the guidance of the preset trajectory.

[0015] Further, step five: Reset the equipment and remove it from the site: After drilling is completed, drive the electric cylinder to run in reverse, drive the water drill to reset to the initial end of the guide rail table, adjust the guide rail table to level with the assistance of the torsion spring, retract the extension plate and unlock the universal wheels, and push the whole machine away from the construction area.

[0016] Compared with the prior art, the beneficial effects of the present invention are: The support assembly allows for quick and easy fixation of the water drill, ensuring verticality and accuracy. The support also fully supports the drill's weight, significantly reducing operator fatigue and enabling single-person drilling operations, thus improving efficiency. Furthermore, the support features a non-slip extension plate and safety locking device, ensuring secure fixation even in complex conditions and preventing accidents caused by drill wobbling. This balances construction quality with personnel safety.

[0017] Through the operation of the support assembly, the guide rail, support slide, and threaded rod form a linear guiding system. The clamping part can move horizontally in a straight line along the guide, which can constrain the water drill to drill only along the preset trajectory, avoiding drilling deviation caused by vibration and uneven manual force, ensuring hole position accuracy. In addition, the rigid frame structure of the support can effectively disperse the vibration energy of the water drill during operation, weaken the impact of vibration on the stability of the support, and transmit the vibration to the ground through the extension plate, reducing the probability of vibration being transmitted to the operator's hands, and further improving the safety of operation.

[0021] Example 1: Reference Figures 1 to 12 As shown, a wellbore wall positioning rock drilling rig includes a support assembly, which provides precise drilling guidance and a stable drilling environment for the water drill 11.

[0022] The support assembly includes a guide component and two support components. The guide component is used to ensure that the water drill 11 can drill along a set route, and the support components are used to stabilize and adjust the drilling posture of the water drill 11.

[0023] The guiding component includes a guide rail 21, on which a supporting slide plate 22 is slidably connected.

Multiple guide rods 27 are fixedly connected in a linear array inside the supporting slide plate 22. Both side pressure plates 26 are slidably connected to guide rod 27. Each guide rod 27 is fitted with a tension spring 28. The two ends of the tension spring 28 are fixedly connected to the sides of the two side pressure plates 26 that are close to each other. The top of each side pressure plate 26 is symmetrically fixedly connected to two guide rods 29. Each side pressure plate 26 is provided with an upper pressure plate 210. The two upper pressure plates 210 are slidably connected to the two adjacent guide rods 29. Each guide rod 29 is fitted with a tension spring 211. The two ends of the tension spring 211 are fixedly connected to the top surface of the side pressure plate 26 and the lower surface of the upper pressure plate 210, respectively. The top surface of each side pressure plate 26 is threaded with a pressure rod 212.

[0024] Among them, the side pressure plate 26 is set in L shape, and the side of the two side pressure plates 26 that is close to each other is set with a frosted rubber anti-slip surface.

[0025] Among them, the two upper pressure plates 210 are staggered, and the lower surface of the upper pressure plate 210 is a rubber anti-slip surface with a frosted treatment.

[0026] Among them, the pressure rod 212 and the support slide plate 22 are in a pressing fit.

[0027] The top surface of the upper pressure plate 210 is equipped with a handle for easy operation by the user.

[0028] Two support components are symmetrically arranged at the bottom of the guide rail platform 21. Each support component includes two upper legs 31. The tops of each upper leg 31 are symmetrically rotatably connected to two closely spaced gear discs 32, which are fixedly connected to the guide rail platform 21. The tops of each upper leg 31 are symmetrically provided with two torsion springs 33, whose ends are fixedly connected to the upper leg 31 and the adjacent closely spaced gear disc 32, respectively. The bottoms of each upper leg 31 are slidably connected to a lower leg 34. Each upper leg 31 contains a tension spring 35, whose ends are fixedly connected to the top of the inner wall of the upper leg 31 and the top of the lower leg 34, respectively. Each lower leg 34 has multiple slots 36 arranged in a vertical straight array. The two upper legs 31 are connected to each other... A crossbar 37 is fixedly connected between the two sides of the crossbar 37. Two guide rods 38 are symmetrically fixedly connected to the crossbar 37. Each of the two guide rods 38 is fitted with a tension spring 39. A connecting rod 310 is slidably connected to the two guide rods 38. A plug rod 311 is fixedly connected to each end of the connecting rod 310. A wedge block 312 is slidably connected to the bottom of the crossbar 37. A caster wheel 313 is fixedly connected to the bottom of each of the two lower support legs 34. Two slots 314 are opened on each of the two lower support legs 34. An extension plate 315 is slidably connected to the two lower support legs 34. A plug rod 316 is inserted into the top of the extension plate 315. A tension spring 317 is fitted to each end of the plug rod 316. The two ends of the tension spring 317 are fixedly connected to the extension plate 315 and the plug rod 316, respectively.

[0029] Specifically: the top end of the insertion rod 311 is inserted into the toothed disc 32, and the bottom end of the insertion rod 311 is inserted into the slot 36.

[0030] Among them, the second insertion rod 316 and the second slot 314 are inserted and mated.

[0031] Wherein: the top of the wedge block 312 is set as an inclined surface, and the wedge block 312 is pressed into the connecting rod 310.

[0032] Among them, the universal wheel 313 is a known existing technology, and the universal wheel 313 has a self-locking function.

[0033] Among them, the bottom surface of the expansion plate 315 is set as a non-slip surface with a frosted finish.

[0034] In the initial state of the support assembly, i.e. when drilling is not required using the water drill 11, the internal structures of the support assembly are as follows: The support slide plate 22 is located on the guide rail 21 near the electric cylinder 24. The tension spring 28 does not exhibit elastic deformation, and the distance between the two side pressure plates 26 is closest at this time. The tension spring 211 does not exhibit elastic deformation, and the distance between the upper pressure plate 210 and the side pressure plates 26 is closest at this time. The pressure rod 212 is not threaded onto the side pressure plate 26, and the bottom end of the pressure rod 212 does not contact or press against the support slide plate 22. The torsion spring 33 does not exhibit elastic deformation, and the upper support leg 31 is vertically downward at the bottom of the guide rail 21. The tension spring 35 does not exhibit elastic deformation. The top end of the insertion rod 311 engages with the fine-tooth disc 32, and the bottom end of the insertion rod 311 engages with the slot 36 at the very top. The tension spring 39 does not exhibit elastic deformation, the wedge block 312 does not contact or press against the connecting rod 310, the insertion rod 316 engages with the slot 314 at the top, and the tension spring 317 does not exhibit elastic deformation.

[0035] When the user needs to use the water drill 11 for drilling, the support assembly operates as follows: At this point, the user needs to install the water drill 11 first. The user holds the handles on the two upper pressure plates 210 and pulls them to the sides to separate the two upper pressure plates 210. At this time, the two upper pressure plates 210 drive the corresponding side pressure plates 26 to move to the sides, so that the two side pressure plates 26 slide to the sides on the support slide plate 22. At the same time, the two side pressure plates 26 slide to the sides on the guide rod 27, so that the tension spring 28 is pulled and produces elastic deformation.

[0036] Simultaneously, the user pulls the two upper pressure plates 210 upwards, causing them to slide upwards on the guide rod 29. This causes the tension spring 211 to elastically deform, resulting in the two side pressure plates 26 moving away from each other and increasing the distance between them. Meanwhile, the two upper pressure plates 210 move upwards, increasing the distance between them and the side pressure plates 26. As the side pressure plates 26 move away from each other, the two upper pressure plates 210 move synchronously until a gap is exposed between them. This means the distance between the top surface of the supporting slide plate 22, the two side pressure plates 26, and the two upper pressure plates 210 increases. At this point, the supporting slide plate 22, the side pressure plates 26, and the upper pressure plates 210 form a rectangular gap with an open top.

[0037] After completion, while keeping the two upper pressure plates 210 pulled, the user inserts the water drill 11 into the rectangular gap, so that one end of the drill bit of the water drill 11 faces away from the electric cylinder 24. At this time, the water drill 11 is in contact with the top surface of the support slide plate 22. Then, the user stops pulling the two upper pressure plates 210. At this time, under the elastic restoring action of the tension spring 1 28 and tension spring 211, the two side pressure plates 26 are pulled closer to each other, and the two upper pressure plates 210 are pulled downward, so that the two side pressure plates 26 are pressed against the sides of the water drill 11, and the two upper pressure plates 210 are pressed against the top of the water drill 11. As the two side pressure plates 26 move closer to each other, the two upper pressure plates 210 move closer to each other simultaneously, so that the two upper pressure plates 210 overlap at the top of the water drill 11. At this time, the bottom of the water drill 11 is pressed against by the support slide plate 22, the two sides of the water drill 11 are pressed against by the two side pressure plates 26 through the rubber anti-slip surface, and the top of the water drill 11 is pressed against by the two upper pressure plates 210 through the rubber anti-slip surface. Under the elastic force of the tension spring 1 28 and tension spring 211, the side pressure plates 26 and upper pressure plates 210 always apply inward pressure to the water drill 11, thereby forming a wrap-around clamping and limiting of the water drill 11, thus limiting the water drill 11 on the support slide plate 22. After completion, the user tightens the two pressure rods 212 by screwing them together, so that the bottom ends of the two pressure rods 212 abut against the top surface of the support plate 22. This limits the two side pressure plates 26 on the support plate 22 by limiting the pressure rods 212 on the support plate 22, thus limiting the clamping and limiting state of the water drill 11, and thus firmly clamping and limiting the water drill 11 on the support plate 22.

[0038] After completion, the user needs to move the water drill 11 to the construction site and adjust its drilling path according to the construction requirements. At this point, the user can move the guide rail 21 by pushing the casters 313, causing the guide rail 21 to move around the construction site as needed until the drill bit of the water drill 11 faces the hole to be drilled. However, at this point, the drill bit of the water drill 11 is not yet aligned with the hole to be drilled, and the user needs to adjust the position and orientation of the water drill 11, as follows: The user pushes the wedge 312 upward, causing it to slide upward on the crossbar 37. As the wedge 312 moves upward, its inclined surface abuts against and presses against the connecting rod 310. Guided by the inclined surface, the connecting rod 310 is pushed away from the crossbar 37. At this time, the connecting rod 310 slides on the two guide rods 38, causing the tension spring 39 to undergo elastic deformation. The user pushes the wedge 312 upward until its inclined surface no longer abuts against the connecting rod 310. At this time, the wedge 312 is clamped between the connecting rod 310 and the crossbar 37. Due to the obstruction of the wedge 312, the tension spring 39 cannot elastically return to its original position, thus fixing the position of the connecting rod 310.

[0039] As the connecting rod 310 is limited to the side of the guide rod 38 away from the crossbar 37, the connecting rod 310 drives the two insert rods 311 at both ends to move synchronously, so that the insert rods 311 move away from the upper support leg 31. Then, the top of the insert rod 311 is no longer engaged with the toothed disc 32, and the bottom of the insert rod 311 is pulled out from the slot 36. Then, the upper support leg 31 is no longer restricted from rotating, and the lower support leg 34 is no longer restricted from sliding within the upper support leg 31.

[0040] At this point, the height of the water drill 11 needs to be adjusted so that it is flush with the hole to be drilled. The user then presses down on the guide rail 21, causing the upper support leg 31 to slide down on the lower support leg 34. Simultaneously, the tension spring 35 undergoes elastic deformation until the water drill 11 moves to the required height. Then, the user pulls down on the wedge block 312, causing it to move down until it is no longer in the position of the connecting rod 310. At this point, under the elastic reset action of the tension spring 49, the tension spring 49 pulls the connecting rod 310 to move and reset towards the crossbar 37. As the connecting rod 310 moves and resets, it drives the insertion rods 311 at both ends to reset synchronously. This allows the top of the insertion rod 311 to engage with the toothed disc 32, and the bottom of the insertion rod 311 to insert into the slot 36 at the current position, thereby limiting the lower support leg 34 to the upper support leg 31, thus fixing the height of the water drill 11 off the ground.

[0041] If the water drill 11 needs to be drilled at an inclined angle, that is, the pitch angle of the drill bit end of the water drill 11 needs to be adjusted. At this time, the user keeps the wedge 312 clamped between the crossbar 37 and the connecting rod 310, so that the upper support leg 31 and the lower support leg 34 are no longer locked. The user can adjust the two support components separately. Specifically, the user can adjust the height position of the two ends of the guide rail 21, so that the guide rail 21 rotates on the upper support leg 31 and drives the fine toothed disc 32 to rotate synchronously. At the same time, the torsion spring 33 produces elastic deformation. During this process, the upper support leg 31 and the lower support leg 34 always remain in a vertical state. Meanwhile, the upper support leg 31 slides on the lower support leg 34 to adapt to the height change of the end of the guide rail table 21 after it rotates. After the pitch angle of the guide rail table 21 is adjusted, the user moves the wedge block 312 downward so that the insertion rod 311 is reset to reconnect the fine-tooth disc 32 with the slot 36 at the current position, thereby locking the posture of the guide rail table 21 at this time, that is, locking the tilt angle of the water drill 11.

[0042] After completion, the user locks the caster 313 to restrict its rotation, and then pulls the second insertion rod 316 away from the lower support leg 34. At the same time, the tension spring 317 undergoes elastic deformation, causing the second insertion rod 316 to be pulled out of the slot 314. After completion, while keeping the second insertion rod 316 pulled, the user pushes the extension plate 315 downward until the extension plate 315 touches the ground of the construction site. After completion, the user stops pulling the second insertion rod 316. Under the elastic reset action of the tension spring 317, the second insertion rod 316 inserts into the slot 314 at the bottom, fixing the position of the extension plate 315. Since the caster 313 is locked and rotating, the extension plate 315 touches the ground of the construction site, thus restricting the movement of the guide rail 21. At this time, the extension plate 315 increases the contact area between the guide rail 21 and the ground, which can better disperse the vibration generated by the water drill 11 during operation.

[0043] At this point, the installation and positioning adjustment of the water drill 11 are complete. The user can drive the electric cylinder 24 to rotate the threaded rod 23. When the threaded rod 23 rotates, the support slide plate 22 tends to deflect along the thread direction. However, the deflection of the support slide plate 22 is restricted by the guide rail 21, so that the support slide plate 22 can only slide along the axial direction of the guide rail 21. As the electric cylinder 24 runs, the support slide plate 22 moves along the axial direction of the guide rail 21. At the same time, the support slide plate 22 drives the water drill 11, which is limited on it, to move synchronously, pushing the water drill 11 to move linearly towards the position to be drilled. During this process, the user can drive the water drill 11 to run, so that the water drill 11 drills while being guided and moved.

[0044] After drilling is completed, the user needs to reset the water drill 11. At this time, the user drives the output shaft of the electric cylinder 24 to rotate in the opposite direction, so that the water drill 11 moves to the end of the guide rail table 21 near the electric cylinder 24. Then the user pushes the wedge block 312 upward. With the elastic reset assistance of the torsion spring 33, the guide rail table 21 is adjusted to a horizontal state. After completion, the wedge block 312 moves down to reset. Then the second insertion rod 316 is inserted into the slot 314 located at the top, so that the extension plate 315 moves upward until it is no longer in contact with the ground. At this time, the user can directly push the guide rail table 21 away from the construction site.

[0045] It should be noted that in the above process, the function of tension spring 35 is to provide auxiliary force when adjusting the height of the guide rail 21 and the tilt angle of the water drill 11, making the adjustment easier.

[0046] The function of the extension plate 315 is to increase the contact area with the ground, achieve anti-slip and improve the anti-overturning moment, and at the same time disperse the vibration of the water drill 11 during operation, ensuring the stability of the water drill 11 drilling construction.

[0047] In summary, the following beneficial effects can be achieved through the operation of the support assembly: The support assembly allows for quick and easy fixation of the water drill 11, ensuring drilling verticality and accuracy. Simultaneously, the weight of the water drill 11 is fully supported by the support, significantly reducing the operator's physical exertion. Drilling can be completed by a single person, improving construction efficiency. Furthermore, the support is equipped with a non-slip extension plate 315 and a safety locking device, ensuring secure fixation even in complex working conditions and preventing accidents caused by the water drill 11 shaking. This balances construction quality and personnel safety.

[0048] Through the operation of the support assembly, the guide rail 21, support slide plate 22, and threaded rod 23 form a linear guiding system. The clamping part can move horizontally in a straight line along the guide, which can constrain the water drill 11 to drill only along the preset trajectory, avoiding drilling deviation caused by vibration and uneven manual force, ensuring hole position accuracy. In addition, the rigid frame structure of the support can effectively disperse the vibration energy of the water drill 11 during operation, weaken the impact of vibration on the stability of the support, and transmit the vibration to the ground through the extension plate 315, reducing the probability of vibration being transmitted to the operator's hands, and further improving the safety of operation.

[0049] Example 2: A method for constructing a wellbore wall-positioning rock drilling rig includes the following steps: Step 1: Install and position the water drill 11: The user holds the handle of the upper pressure plate 210 and pulls it to the sides and upwards to separate the two upper pressure plates 210 and the two side pressure plates 26, causing the tension springs 1 28 and 2 11 to undergo elastic deformation, forming a rectangular gap with an opening at the top. Then, the water drill 11 is placed into the gap and the upper pressure plate 210 is released. Under the action of elasticity, the side pressure plates 26 and the upper pressure plate 210 hug and clamp the water drill 11. Finally, the pressure rod 212 is tightened to press and cooperate with the support slide plate 22 to lock the clamping state.

[0050] Step 2: Moving and coarsely adjusting the position of the equipment: Push the guide rail table 21 and move the whole machine to the construction area through the casters 313, so that the drill bit end of the water drill 11 is aligned with the vicinity of the hole to be drilled.

[0051] Step 3: Fine-tuning the equipment posture and fixing: Push the wedge block 312 upward to limit the connecting rod 310, unlock the insertion of the first insertion rod 311 into the toothed disc 32 and the slot 36. Press the guide rail 21 as needed to adjust the height from the ground, or rotate the guide rail 21 to adjust the tilt angle. After adjustment, move the wedge block 312 down to reset the first insertion rod 311, lock the height and angle, then pull the second insertion rod 316 to move the extension plate 315 down to contact the ground and fix it. Lock the caster wheel 313 to complete the overall machine stabilization.

[0052] Step 4: Start the drilling machine to carry out drilling: Drive the electric cylinder 24 to rotate the threaded rod 23, so that the support plate 22 slides along the guide rail 21 axially, and simultaneously drive the water drill 11 to move to the position to be drilled. At the same time, start the water drill 11 and complete the drilling construction under the guidance of the preset trajectory.

[0053] Step 5: Reset the equipment and remove it from the site: After drilling is completed, drive the electric cylinder 24 to run in reverse, drive the water drill 11 to reset to the initial end of the guide rail table 21, adjust the guide rail table 21 to the horizontal with the assistance of the torsion spring 33, retract the extension plate 315 and unlock the universal wheels 313, and push the whole machine away from the construction area.
