Abstract
Description
Technical Field
[0001] This invention relates to the field of drainage technology for dredged fill soil, and in particular to a device for constructing a drainage structure for dredged fill soil. Background Technology
[0002] Drainage strips, also commonly known as plastic drainage boards, are drainage materials composed of a core board and a filter membrane. In dredged soil filling sites, after being inserted, drainage strips act like countless tiny pipes, providing a rapid drainage channel for water in the dredged soil. Under load (such as the self-weight of the fill or vacuum preloading), pore water in the soil will flow upward or to the sides through the drainage strips and eventually drain out of the site, thereby accelerating soil consolidation and improving the strength and stability of the foundation.
[0003] Currently, during the process of inserting drainage belts into the hydraulic fill, anchor plates are usually required before each insertion to prevent the drainage belt from being pulled up by the drill rod during the ascent. This method requires manual repetition of cutting the drainage belt and installing anchor plates, resulting in decreased work efficiency.
[0004] Therefore, how to achieve automatic fixing and release of the drainage belt during insertion, and how to prevent the drainage belt from being accidentally pulled out during the drill pipe rising process, have become urgent problems to be solved. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to provide a device for constructing a drainage structure for dredged fill soil, in view of the above-mentioned problems.
[0006] The technical solution adopted in this invention is: a device for constructing a drainage structure for dredged fill soil, comprising: The moving mechanism has a rectangular hole at the top and a tower that corresponds to the rectangular hole. The top and bottom of the tower are equipped with support plates, and the adjacent side of the tower is equipped with a winding shaft that can wind up the drainage belt. The moving mechanism can drive the entire device to move. The drive mechanism is located between the top and bottom support plates. Its output end is connected to a drill rod located inside the tower and arranged vertically. The drill rod has a chamber inside that can deliver the drainage belt. The drive mechanism can drive the drill rod to rise or fall vertically. The clamping mechanism is located on the outer wall of the drill pipe, with its output end extending to the inner bottom of both ends of the drill pipe. It can clamp and fix the end of the drainage strip that passes through the internal cavity of the drill pipe. The cutting mechanism, located inside the rectangular hole, can cut the drainage strip at the end after the drill rod rises and resets.
[0007] Using the above-mentioned technical means, when the drainage belt is driven into the dredged soil, the drainage belt inside the drill rod is first clamped by the clamping mechanism. The drill rod is driven down by the drive mechanism, so that the clamped drainage belt can descend with the drill rod until it is inserted into the dredged soil. When the drill rod needs to be reset, the clamping mechanism is used to release the clamping of the drainage belt, and the drive mechanism is used to drive the drill rod up until the drill rod is reset. Then, the cutting mechanism is used to cut the drainage belt, thus realizing the mechanized cutting operation of the drainage belt.
[0008] In some embodiments, the driving mechanism includes a motor, rollers, a first support plate, a second support plate, a connecting belt, a connecting plate, and a transmission assembly. A set of first support plates and a set of second support plates are symmetrically arranged inside the top support plate, and a set of first support plates is symmetrically arranged inside the bottom support plate. The top first support plate corresponds to the bottom first support plate. Rollers are rotatably connected inside both sets of first support plates. A closed connecting belt is sleeved between the top and bottom rollers. The belt surface of the connecting belt is connected to the top end of the drill rod via the connecting plate. The connecting plate has a through groove that communicates with the internal cavity of the drill rod. A motor capable of driving the corresponding roller to rotate is installed on the side wall of the bottom first support plate. A pushing assembly is installed inside the second support plate. The pushing assembly is drively connected to the roller in the top first support plate. The pushing assembly can push the drainage belt to descend synchronously when the drill rod descends.
[0009] In some embodiments, the pushing assembly includes a conveying roller, a shaft, a pulley, a connecting shaft, a limiting ring, an annular plate, a rubber ring, and a first transmission member. A pair of parallel conveying rollers are rotatably connected between a pair of second support plates. The drainage belt on the take-up shaft passes through the conveying rollers and is fed into the internal cavity of the drill rod. The outer wall of the second support plate on the same side as the motor is provided with a pulley and a connecting shaft respectively corresponding to the conveying rollers. The outer wall of the second support plate is connected with a limiting ring located on the outer ring of the connecting shaft. The inner wall of the limiting ring is connected with a rubber ring that can abut against the outer wall of the connecting shaft. The outer wall of the opposite second support plate is provided with a gear corresponding to the conveying roller. The gears at the ends of the two conveying rollers mesh with each other. The outer wall of the first support plate on the same side as the pulley is provided with a shaft. The shaft is connected to the end of the roller. An annular plate is connected to the outside of the shaft via the first transmission member. The annular plate is connected to the pulley. The first transmission member can drive the annular plate to rotate in one direction when the drill rod descends.
[0010] In some embodiments, the first transmission member includes a limiting block, a connecting block, a plate, and a spring. The inner wall of the annular plate is provided with limiting blocks at equal intervals, and the outer wall of the shaft is provided with a connecting block that corresponds to the limiting block. The connecting block is hinged to the plate, and the end of the plate away from the connecting block is connected to the outer wall of the shaft by a spring, so that the shaft rotates until the end of the plate abuts against the limiting block, thereby driving the annular plate to rotate.
[0011] In some embodiments, a connecting sleeve is provided on the outside of the annular plate, and the connecting sleeve is connected to the pulley via a transmission belt.
[0012] In some embodiments, the clamping mechanism includes an air supply pipe, a rubber diaphragm, and an air supply assembly. The inner walls at both ends of the drill rod are provided with mounting grooves along their own axial direction. The bottom of the inner walls at both ends of the drill rod are provided with fixing grooves that can communicate with the mounting grooves. A rubber diaphragm is provided in the fixing grooves. An air supply pipe is embedded in the mounting grooves. One end of the air supply pipe faces the rubber diaphragm, and the other end of the air supply pipe extends to the outside of the drill rod and is connected to an air supply assembly installed on the outer wall of the drill rod. The air supply assembly is used to supply air to the air supply pipe to control the expansion and clamping or contraction and release of the internal drainage strip by the rubber diaphragms on both sides.
[0013] In some embodiments, the gas supply assembly includes a drive component, a fixed plate, a sleeve, a piston, a rod, a transmission plate, a connecting pipe, a solenoid valve, and a gas delivery pipe. The outer wall of the drill rod is provided with a pair of fixed plates and a drive component on the same axis. The pair of fixed plates are connected to sleeves that can be arranged in opposite directions. A rod is provided between the two sleeves. The two ends of the rod are slidably connected to the corresponding sleeves via pistons. A transmission plate is sleeved at the middle of the outer wall of the rod. The side walls of the two sleeves are connected by a connecting pipe. Solenoid valves are provided at both ends of the connecting pipe. The side wall of the connecting pipe is connected to the gas delivery pipe. The output end of the drive component is connected to the transmission plate. The drive component can drive the rod to slide vertically via the transmission plate to adjust the relative air pressure between the upper sleeve and the lower sleeve, so that the gas in the sleeve can be introduced into the gas delivery pipe or the gas in the gas delivery pipe can be recovered into the sleeve.
[0014] In some embodiments, the cutting mechanism includes a cutting blade, a blade holder, and cylinders. A set of cylinders is symmetrically installed inside the rectangular hole, and the output ends of the set of cylinders are mounted with cutting blades arranged horizontally opposite each other via the blade holder.
[0015] In some embodiments, the mobility mechanism includes a tracked vehicle.
[0016] In some embodiments, the support plate at the bottom is provided with a guide plate located above the cutting mechanism, and the guide plate is provided with a guide groove, through which the drill rod slides.
[0017] The beneficial effects of this invention are: 1. The end of the drainage belt is clamped and fixed by the clamping mechanism, so that when the drive mechanism drives the drill rod to drill into the backfill, the clamping mechanism can pull the drainage belt. The drainage belt is inserted into the backfill along with the drill rod. After the drainage belt is inserted to the preset depth, the clamping mechanism releases the clamping and fixing of the drainage belt. The drive mechanism drives the drill rod to rise and reset, while the drainage belt is retained in place by the friction between its end and the soil. After the drill rod is reset, the cutting mechanism cuts the drainage belt to realize the mechanized operation of the whole process, which can support continuous operation and eliminate the need for frequent manual operation, thus improving construction efficiency.

Specific features, structures, or characteristics may be combined in any suitable manner consistent with this disclosure.
[0027] The term "comprising" is open-ended. As used in the appended claims, it does not exclude additional structures or steps.
[0028] "First," "second," etc. As used in this article, these terms serve as labels for the nouns preceding them and do not imply any type of ordering (e.g., spatial, temporal, logical, etc.). Detailed Implementation
[0029] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below with reference to specific embodiments.
[0030] Combination Figures 1 to 7 As shown, this embodiment is a device for constructing a drainage structure for dredged fill, including a moving mechanism 1, a driving mechanism, a clamping mechanism, and a cutting mechanism. The moving mechanism 1 has a rectangular hole 38 at its top, and a tower 2 corresponding to the rectangular hole 38 is located at the top of the moving mechanism 1. Support plates 4 are provided at the top and bottom of the tower 2, and a winding shaft 3 capable of winding up the drainage tape is provided on the adjacent side of the tower 2. The moving mechanism 1 can drive the entire device to move. A driving mechanism is provided between the top support plate 4 and the bottom support plate 4. The output end of the driving mechanism is connected to a drill rod 14, which is located inside the tower 2 and is arranged vertically. The drill rod 14 has a chamber inside that can transport the drainage tape. The driving mechanism can drive the drill rod 14 to rise or fall vertically. A clamping mechanism is provided on the outer wall of the drill rod 14, and the output end of the clamping mechanism extends to the inner bottom of both ends of the drill rod 14. The clamping mechanism can clamp and fix the end of the drainage tape passing through the inner chamber of the drill rod 14. A cutting mechanism is provided inside the rectangular hole 38. The cutting mechanism can cut the drainage strip at the end after the drill rod 14 rises and resets.
[0031] When the drill rod 14 needs to be lowered, the end of the drainage belt is clamped by the clamping mechanism. As the drill rod 14 is lowered and inserted into the fill soil, the drainage belt is pulled down along with the drill rod 14, eliminating the need for manual installation of a device to fix the drainage belt and ensuring that the drainage belt can be properly inserted into the fill soil. When the drill rod 14 and the drainage belt are inserted into the fill soil to a preset depth, and the drill rod 14 needs to be raised, the clamping mechanism releases its grip on the drainage belt. Because there is a certain conveying space inside the drill rod 14 and the drainage belt, and the end of the drainage belt is retained in place by the friction of the fill soil, the drill rod 14 can rise under the drive of the drive mechanism. After the drill rod 14 is reset, the drainage belt is cut by the cutting mechanism, eliminating the need for manual cutting operations and achieving fully automated drainage belt laying.
[0032] Furthermore, in this embodiment, the moving mechanism 1 includes a tracked vehicle.
[0033] The entire device is moved by a tracked vehicle, which is adapted to soft foundations and can move freely in muddy areas, thus moving to the next insertion point after completing a single operation.
[0034] Furthermore, the bottom support plate 4 is provided with a guide plate 13 located above the cutting mechanism. The guide plate 13 is provided with a guide groove, and the drill rod 14 slides through the guide groove of the guide plate 13.
[0035] In some implementation schemes, such as Figure 2 and Figure 3 As shown, the drive mechanism includes a motor 15, rollers 7, a first support plate 5, a second support plate 8, a connecting belt 6, a connecting plate 11, and a transmission assembly. A set of first support plates 5 and a set of second support plates 8 are symmetrically arranged inside the top support plate 4, and a set of first support plates 5 are symmetrically arranged inside the bottom support plate 4. The top first support plate 5 corresponds to the bottom first support plate 5. Rollers 7 are rotatably connected inside both sets of first support plates 5. A closed connecting belt 6 is fitted between the top and bottom rollers 7. The belt surface of the connecting belt 6 is connected to the top end of the drill rod 14 via the connecting plate 11. The connecting plate 11 has a through groove that can communicate with the internal cavity of the drill rod 14. A motor 15 capable of driving the corresponding roller 7 to rotate is installed on the side wall of the bottom first support plate 5. A pushing assembly is installed inside the second support plate 8. The pushing assembly is drively connected to the roller 7 inside the top first support plate 5. The pushing assembly can push the drainage belt to descend synchronously when the drill rod 14 descends.
[0036] The bottom roller 7 is driven to rotate by the motor 15. The top and bottom rollers 7 are connected by a connecting belt 6. During rotation, the connecting belt 6 drives the connecting plate 11 and the drill rod 14 to move vertically up and down. The connecting plate 11 has a through groove for the drainage belt to pass through, so as not to affect the conveying path of the drainage belt. The guide plate 13 slides with the drill rod 14, so that the guide plate 13 provides lifting guidance for the drill rod 14 to ensure the smooth operation of the drill rod 14 and avoid the drill rod 14 from tilting or shaking.
[0037] Furthermore, such as Figure 4 As shown, the pushing assembly includes a conveying roller 10, a shaft 25, a pulley 22, a connecting shaft 21, a limiting ring 19, an annular plate 16, a rubber ring 20, and a first transmission component. A pair of parallel conveying rollers 10 are rotatably connected between a pair of second support plates 8. The drainage belt on the take-up shaft 3 passes through the conveying rollers 10 and is fed into the internal cavity of the drill rod 14. The outer wall of the second support plate 8, located on the same side as the motor 15, is provided with pulleys 22 and connecting shafts 21 respectively connected to the conveying rollers 10. The outer wall of the second support plate 8 is connected to a limiting ring 19 located on the outer ring of the connecting shaft 21. The inner wall of the limiting ring 19 is connected to a rubber ring 20 that can abut against the outer wall of the connecting shaft 21. The outer wall of the second support plate 8 on the opposite side is provided with a gear 9 that is connected to the conveying roller 10. The gears 9 located at the ends of the two conveying rollers 10 mesh with each other. The outer wall of the first support plate 5 located on the same side as the pulley 22 is provided with a shaft 25. The shaft 25 is connected to the end of the roller 7. The shaft 25 is connected to an annular plate 16 via a first transmission component. The annular plate 16 is connected to the pulley 22. The first transmission component can drive the annular plate 16 to rotate in one direction when the drill rod 14 descends.
[0038] When the drill rod 14 descends, the top roller 7 rotates, driving the shaft 25, which in turn drives the first transmission component. The first transmission component triggers the annular plate 16 to rotate, which in turn drives the belt 23 to drive the pulley 22. The pulley 22 drives the conveyor roller 10 to rotate. Since the ends of the conveyor roller 10 are engaged with the gear 9, the two conveyor rollers 10 rotate in opposite directions. Thus, while the drill rod 14 descends, the drainage belt can be automatically pushed into the chamber of the drill rod 14, ensuring continuous operation. When the drill rod 14 rises, the gear 9 cannot drive the conveyor roller 10 to rotate. The friction between the rubber ring 20 and the connecting shaft 21 can lock the conveyor roller 10, ensuring that the drainage belt is not driven.
[0039] Furthermore, the first transmission component includes a limiting block 26, a connecting block 28, a plate 27, and a spring 29. The inner wall of the annular plate 16 is provided with equally spaced limiting blocks 26, each with an inclined surface structure. The outer wall of the shaft 25 is provided with a connecting block 28 corresponding to the limiting blocks 26. The connecting block 28 is hinged to the plate 27. The end of the plate 27 away from the connecting block 28 is connected to the outer wall of the shaft 25 via the spring 29, allowing the shaft 25 to rotate until the plate 27 abuts against the end of the limiting block 26, thereby driving the annular plate 16 to rotate. Specifically, corresponding connecting blocks 28, plate 27, and limiting blocks 26 form a group; in this embodiment, three groups are provided.
[0040] Furthermore, a connecting sleeve 24 is fitted around the annular plate 16, and the connecting sleeve 24 is connected to the pulley 22 via a transmission belt 23.
[0041] When the drill rod 14 descends, the bottom roller 7 is driven by the motor 15 to rotate in the first direction. The bottom roller 7 drives the top roller 7 to rotate via the connecting belt 6. The roller 7 drives the shaft 25 to rotate accordingly. When the shaft 25 rotates, it drives the plate 27 to rotate via the connecting block 28. Under the elastic action of the spring 29, the end of the plate 27 abuts against the inner wall of the annular plate 16. Then, when the plate 27 contacts the limiting block 26, it drives the annular plate 16 to rotate. Through the transmission cooperation of the connecting sleeve 24, the pulley 22 and the transmission belt 23, the conveying roller 10 corresponding to the pulley 22 is driven to rotate. Through the meshing of the two gears 9 on one side of the pair of conveying rollers 10, the two conveying rollers 10 rotate in opposite directions, thereby realizing the conveying of the drainage belt to the internal cavity of the drill rod 14.
[0042] When the drill rod 14 rises, the motor 15 drives the roller 7 to rotate in the second direction, which is the opposite of the first direction. The bottom roller 7 drives the top roller 7 to rotate via the connecting belt 6. The roller 7 correspondingly drives the shaft 25 to rotate, and the shaft 25 drives the connecting block 28 and the hinged plate 27 to rotate. Due to the inclined structure of the limiting block 26 on the inner wall of the annular plate 16 and the elasticity of the spring 29, the plate 27 rotates around the connecting block 28. At the same time, the plate 27 slides along the inclined surface of the limiting block 26, and the plate 27 will not push the annular plate 16 to rotate continuously. The friction between the connecting shaft 21 and the rubber ring 20 can prevent the conveying roller from rotating, so that the two conveying rollers 10 remain fixed, thus ensuring that the drainage belt is not driven to rise during the rise of the drill rod 14.
[0043] In some implementation schemes, such as Figure 5 and Figure 6As shown, the clamping mechanism includes an air supply pipe 35, a rubber diaphragm 36, and an air supply assembly. The inner walls at both ends of the drill rod 14 have mounting grooves 37 along their axial direction. The bottom of the inner walls at both ends of the drill rod 14 has fixing grooves that connect to the mounting grooves 37. A rubber diaphragm 36 is placed in the fixing grooves. An air supply pipe 35 is embedded in the mounting grooves 37. One end of the air supply pipe 35 faces the rubber diaphragm 36, and the other end extends to the outside of the drill rod 14 and is connected to an air supply assembly installed on the outer wall of the drill rod 14. The air supply assembly is used to supply air to the air supply pipe 35 to control the expansion and clamping or contraction and release of the internal drainage strip by the rubber diaphragms 36 on both sides. Specifically, in this embodiment, the rubber diaphragm 36 is made of wear-resistant rubber to ensure a certain degree of fatigue resistance and stability of the clamping effect under repeated deformation.
[0044] The air supply assembly controls the air supply pipe 35 to ventilate or ventilate. Changes in the internal air pressure of the air supply pipe 35 cause the rubber membrane 36 to expand or contract. When it expands, it can clamp the end of the drainage strip; when it contracts, it releases the drainage strip. In this embodiment, the rubber membrane 36 is used as a flexible clamp, which will not damage the surface of the drainage strip.
[0045] Furthermore, such as Figure 5 As shown, the air supply assembly includes a drive component, a fixed plate 17, a sleeve 18, a piston 30, a rod 32, a transmission plate 31, a connecting pipe 34, a solenoid valve 33, and an air supply pipe 35. The outer wall of the drill rod 14 is provided with a pair of fixed plates 17 and a drive component on the same axis. The pair of fixed plates 17 are connected to sleeves 18 arranged facing each other. A rod 32 is provided between the two sleeves 18. Pistons 30 are fixed to both ends of the rod 32, and the pistons 30 are slidably connected to the corresponding sleeves 18. The middle portion of the outer wall of the rod 32... A transmission plate 31 is provided, and the side walls of the two sleeves 18 are connected by a connecting pipe 34. Both ends of the connecting pipe 34 are equipped with solenoid valves 33. The side wall of the connecting pipe 34 is connected to a gas supply pipe 35. The output end of the driving component is connected to the transmission plate 31. The driving component can drive the sleeve rod 32 to slide vertically via the transmission plate 31, thereby adjusting the relative air pressure between the upper and lower sleeves 18, allowing gas in the sleeves 18 to flow into the gas supply pipe 35 or gas in the gas supply pipe 35 to be returned to the sleeves 18. Specifically, in this embodiment, the driving component includes an electric push rod 12, which is installed on the outer wall of the drill rod 14. The output end of the electric push rod 12 is connected to the transmission plate 31. The electric push rod 12 and the sleeve rod 32 are arranged parallel to each other, and the electric push rod 12 pushes the transmission plate 31 to drive the sleeve rod 32 to slide along its own axial direction.
[0046] Considering the large size and inconvenient installation of the air pump, this embodiment uses air pressure adjustment to control the rubber diaphragm 36 to achieve the clamping effect. Initially, the piston at the top of the sleeve 32 is located at the inner top of the upper sleeve 18. By activating the electric push rod 12, the electric push rod 12 drives the transmission plate 31 to move, causing the transmission plate 31 to descend. The transmission plate 31 causes the sleeve 32 to slide downwards towards the lower sleeve 18, resulting in a decrease in the air pressure inside the upper sleeve 18 and an increase in the air pressure inside the lower sleeve 18. This activates the lower solenoid valve 33, allowing the gas in the lower sleeve 18 to enter the air supply pipe 35 through the solenoid valve 33 and the connecting pipe 34. This causes the rubber diaphragm 36 to expand and deform, squeezing the drainage strip between the two rubber diaphragms 36, thus fixing the drill rod 14 and the drainage strip together.
[0047] In some implementation schemes, such as Figure 7 As shown, the cutting mechanism includes a cutting blade 41, a blade holder 40, and a cylinder 39. A set of cylinders 39 are symmetrically installed inside the rectangular hole 38. The output ends of the set of cylinders 39 are connected to the cutting blades 41 arranged horizontally opposite each other via the blade holder 40.
[0048] After the drill rod 14 is fully raised, the switches of the two cylinders 39 are turned on. When the two cylinders 39 are working, they drive the two tool holders 40 and the cutting blades 41 to cut horizontally relative to each other, thereby cutting the drainage belt through the two cutting blades 41 that are close to and abutting each other.
[0049] The implementation principle of a dredged fill drainage structure construction device is as follows: When in use, first wind the drainage belt onto the winding shaft 3, then stretch the drainage belt upwards until it passes between the two conveying rollers 10 from above, and finally pass the drainage belt through the drill rod 14 until it passes through the bottom of the drill rod 14.
[0050] The device is then moved to a suitable position by a tracked vehicle. The switch of the electric push rod 12 is turned on. When the electric push rod 12 is working, it drives the transmission plate 31 to descend. The transmission plate 31 drives the sleeve rod 32 to move downward to the sleeve 18, which reduces the air pressure inside the upper sleeve 18 and increases the air pressure inside the lower sleeve 18. The switch of the lower solenoid valve 33 is turned on, which allows the gas in the lower sleeve 18 to enter the air supply pipe 35 through the solenoid valve 33 and the connecting pipe 34. This causes the rubber diaphragm 36 to expand and deform. The rubber diaphragms 36 at both ends squeeze the drainage belt towards the middle, thus fixing the drill rod 14 and the drainage belt.
[0051] When the motor 15 is switched on, it drives the connecting belt 6 to rotate via the roller 7. The enclosed connecting belt 6 drives the top roller 7 to rotate, which in turn drives the drill rod 14 to move via the connecting plate 11, causing the drill rod 14 to descend and insert the drainage belt into the backfill. During the rotation of the upper roller 7, the shaft 25 rotates. When the shaft 25 rotates, it drives the plate 27 to rotate via the connecting block 28. Under the action of the spring 29, the end of the plate 27 abuts against the inner wall of the annular plate 16. When the plate 27 contacts the limiting block 26 at the bottom, it drives the annular plate 16 to rotate. Through the action of the connecting sleeve 24, the pulley 22 and the transmission belt 23, the conveying roller 10 is driven to rotate. Through the action of the two gears 9, the two conveying rollers 10 rotate in opposite directions, thereby realizing the conveying of the drainage belt. This reduces the friction between the drainage belt and the drill rod 14 during the descent of the drill rod 14, thus ensuring that the drainage belt can be smoothly inserted into the backfill.
[0052] During the reset process, the upper solenoid valve 33 is first switched on, and the gas in the gas supply pipe 35 enters the upper sleeve 18 through the connecting pipe 34, so that the rubber diaphragm 36 is reset, releasing the fixation between the drainage belt and the drill rod 14. Finally, the electric push rod is controlled to drive the transmission plate 31 and the sleeve rod 32 to reset, and the solenoid valve 33 is closed after reset.
[0053] When the roller 7 rotates in the reverse direction, the inclined structure of the side wall of the limiting block 26 causes the plate 27 to rotate around the connecting block 28. Combined with the friction between the connecting shaft 21 and the rubber ring 20, the two conveying rollers 10 remain fixed, thus ensuring that the drainage belt is not conveyed during the rise of the drill rod 14.
[0054] When the drill rod 14 is fully raised above the rectangular hole 38, the switches of the two cylinders 39 are turned on. When the two cylinders 39 are working, they drive the two tool holders 40 and the cutting blades 41 to move closer to each other. Then, the drainage strip exposed at the bottom of the drill rod 14 is cut by the two cutting blades 41 that move closer to each other and abut against each other.
[0055] This device enables automatic clamping, insertion, release, and cutting of drainage tape, significantly reducing manual intervention and improving construction efficiency.
