Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a device and method for embedding waterproofing material in expansion joints of underground buildings. Background Technology

[0002] In recent years, with my country's rapid economic development, the pace of urbanization has accelerated, the urban population has increased, and the number of motor vehicles has risen year by year, leading to increasing traffic pressure. To improve the traffic environment, my country has adopted various measures. Practice has proven that urban tunnel construction is one of the effective methods to solve urban traffic congestion. The cut-and-cover method in urban tunnel construction is characterized by its low construction difficulty, low cost, and short construction period, and is widely used in urban tunnel construction projects. Most urban cut-and-cover tunnels are constructed using the cast-in-place method. When using the cast-in-place method, the tunnel structure needs to be equipped with an expansion joint every 20-30 meters to prevent expansion and contraction deformation of the tunnel concrete structure caused by changes in temperature and humidity. This also avoids uneven settlement of the tunnel structure causing cracks in the walls or other structural parts. Since the tunnel structure is underground, waterproofing materials need to be installed at the expansion joints.

[0003] For example, Chinese patent CN110387976A discloses a post-embedded waterstop for expansion joints and its installation method. This prior art waterstop is fixed by an anchoring agent, which effectively prevents water leakage at the connection between the waterstop and the concrete. The semi-flexible and semi-rigid waterstop has better durability than traditional rubber-based flexible materials, solving the problem of poor durability of traditional rubber-based flexible materials. Moreover, the waterstop also has a certain elastic deformation capacity, which allows it to adapt to the deformation of uneven settlement of concrete walls. The waterstop is not easily damaged by settlement stretching, and if leakage occurs at the waterstop later, it can be directly repaired by welding, achieving the purpose of easy repair.

[0004] The above has some shortcomings in actual use: 1. The existing waterstops are installed manually. After installation, the position of the new waterstop needs to be manually adjusted to achieve precise alignment with the existing waterstop. However, because the installation joint is filled with anchoring agent, which has a certain degree of adhesion, it is difficult to make fine adjustments to the position of the waterstop after installation, making it difficult to efficiently achieve the installation requirement of precise alignment.

[0005] 2. After the anchoring agent is injected into the installation joint, its fluidity will gradually decrease as the standing time increases. If the fluidity decreases to the critical range, it will increase the resistance to the waterstop installation during subsequent installation, affecting the installation accuracy of the waterstop and failing to guarantee the construction quality.

[0006] Therefore, based on the above-mentioned viewpoints, a device and method for embedding waterproofing material in expansion joints of underground buildings are proposed. Summary of the Invention

[0007] To address the aforementioned problems, this application provides a device for embedding waterproofing materials in underground building expansion joints, employing the following technical solution: It includes a base mechanism, which includes a mouth-shaped seat, and a set of pulleys are symmetrically arranged on the side of the mouth-shaped seat.

[0008] It also includes a mixing mechanism for stirring the anchoring agent in the grouting joint and an adjustment mechanism for adjusting the position of the water-stopping material during installation.

[0009] The adjustment mechanism includes a U-shaped seat that moves laterally on the upper side of the mouth-shaped seat, a slide that moves longitudinally between the inner sides of the U-shaped seat, a second motor installed at the center of the upper side of the slide, and a fixing mechanism installed at the drive end of the second motor.

[0010] The stirring mechanism includes two sets of symmetrically rotating extension tubes mounted on the lower side of the mouth-shaped seat. The lower end of the extension tube is equipped with a stirring head that communicates with it. Both ends of the stirring head are provided with friction plates. The stirring mechanism also includes a deployment component, which drives the two friction plates of each set to move away from each other and press against the inner wall of the fitting seam.

[0011] Preferably, the adjustment mechanism further includes a set of electric cylinders mounted on the upper side of the mouth-shaped seat and located on one side of the girdle-shaped seat, with the telescopic arm end of the electric cylinder facing the girdle-shaped seat and connected thereto.

[0012] Preferably, a horizontal plate is provided on the outer side of the slide block, and a moving groove for longitudinal movement of the slide block is opened on the upper side of the horizontal plate. A set of electric cylinders with telescopic arms facing downward and connected to the horizontal plate is installed on the upper side of the U-shaped seat.

[0013] Preferably, a set of longitudinally running slide rods are symmetrically installed between the inner walls of the moving groove, and an electric cylinder with the end of a telescopic arm connected to the slide is installed on the upper side of the horizontal plate.

[0014] Preferably, the fixing mechanism includes a fixing plate located directly below the horizontal plate, and a U-shaped plate connected to the second drive end of the motor is installed at the center of the upper side of the fixing plate.

[0015] Preferably, a set of suction cups are symmetrically installed on the lower side of the fixing plate, and a negative pressure generator is installed on the upper side of the fixing plate. The driving end of the negative pressure generator is equipped with a multi-port pipe that communicates with the two suction cups.

[0016] Preferably, the stirring mechanism further includes two housings mounted on the upper side of the mouth-shaped seat and respectively above a corresponding set of extension tubes. A motor with the drive end facing downward is installed inside the housing. The upper ends of the two extension tubes in each set extend into the housing and are connected to the end gear of the motor.

[0017] Preferably, the unfolding assembly includes a set of pistons symmetrically arranged inside the stirring head and connected to the friction plate on the same side, with a spring connecting the two pistons in the same set, and a piston 2 adapted to it slidably arranged inside the extension tube.

[0018] Preferably, the extension tube is connected to the stirring head at the center of the side of the stirring head. The area below the piston 2 and the area between the two pistons 1 inside the stirring head form a closed hydraulic chamber. The hydraulic chamber is filled with incompressible hydraulic oil. An extension rod penetrating the outer shell is installed on the upper side of the piston 2. An electric cylinder 4 with the end of the telescopic arm connected to the two extension rods on the same side is installed on the upper side of the outer shell.

[0019] On the other hand, this application also provides a method for embedding waterproofing material in the expansion joints of underground buildings, the method comprising the following steps: S1. Pre-arrangement: Move the device to one side of the expansion joint and place the two mixing heads into the fitting joint; S2, Anchoring agent mixing: The mixing mechanism is used to mix the anchoring agent in the part to be embedded during the movement of the device; S3. Fix the device and use the unfolding component in the stirring mechanism to press the friction plate against the inner wall of the fitting seam; S4. Waterstop plate adjustment: Fine-tune the position of the waterstop plate through the adjustment mechanism to align it with the already installed waterstop plate. S5. Waterstop plate installation: After the position adjustment is completed, the new waterstop plate is installed.

[0020] In summary, this application includes at least one of the following beneficial technical effects: I. In practical application scenarios, the adjustment mechanism configured in this application can perform multi-dimensional adjustments on the waterstop plate fixed on the device, specifically including angle calibration, lateral alignment, and longitudinal position fine-tuning. Through precise control, it can achieve full-range precise alignment with the already installed waterstop plate from a top-down view. Adopting the operation logic of "align first, then install", the new waterstop plate can be directly and seamlessly connected with the installed waterstop plate to form a complete whole after installation. With the rigid adjustment characteristics of the mechanical structure, it not only greatly reduces the human error of the traditional manual adjustment method and ensures the installation accuracy, but also effectively avoids the position adjustment problem caused by the adhesiveness of the anchoring agent after installation, thus improving construction efficiency and sealing reliability of the waterstop system.

[0021] Second, this application is also equipped with a mixing mechanism. When the device carries the newly fixed waterstop plate to the next installation position, the mixing mechanism is started simultaneously to dynamically mix the anchoring agent that has been injected in the installation area. The mixing can significantly improve the fluidity of the anchoring agent, effectively avoiding problems such as increased waterstop plate installation resistance and incomplete installation due to the decrease in the fluidity of the anchoring agent. At the same time, it prevents the installation sealing performance from being affected by uneven distribution of the anchoring agent, ensuring the smoothness of the waterstop plate installation operation and the stability of the installation quality.

[0022] 3. After the mixing mechanism completes the mixing of the anchoring agent, the unfolding mechanism is activated to make the friction plate unfold outward and press tightly against the inner wall of the caulking joint, thereby achieving a stable fixation of the device. When adjusting the operation of the mechanism and making precise adjustments to the position of the waterstop plate, the device displacement caused by the vibration generated by the operation of the mechanism can be effectively avoided, ensuring the stability of the waterstop plate alignment adjustment process and preventing displacement from affecting the alignment accuracy.

[0034] The following is in conjunction with the appendix Figures 1-9 The embodiments of this application will be described in detail.

[0035] This application discloses a device and method for embedding waterstop material in the expansion joint of underground buildings. The configured adjustment mechanism can perform multi-dimensional adjustment of the waterstop plate fixed on the device in actual application scenarios, specifically including angle calibration, lateral alignment and longitudinal position fine adjustment. Through precise control, it can achieve full-range precise alignment with the embedded waterstop plate from a top-down view. Adopting the operation logic of "align first and then embed", the new waterstop plate can be directly and seamlessly connected with the installed waterstop plate to form a complete whole after embedding. With the rigid adjustment characteristics of the mechanical structure, it not only greatly reduces the human error of the traditional manual adjustment method and ensures the installation accuracy, but also effectively avoids the position adjustment problem caused by the adhesiveness of the anchoring agent after embedding, thus improving the construction efficiency and sealing reliability of the waterstop system.

[0036] Example 1: like Figure 1 and Figure 4 As shown, the device includes a base mechanism 1, which includes a mouth-shaped seat 11. A set of pulleys 12 are symmetrically arranged on the side of the mouth-shaped seat 11, allowing the user to move the device by using the pulleys 12.

[0037] like Figures 1-3 and Figure 5 As shown, it also includes an adjustment mechanism 2 for adjusting the position of the water-stopping material during installation. The adjustment mechanism 2 includes a set of slide rods 21 arranged laterally on the upper side of the orifice seat 11. The sculpted seat 22 is slidably arranged laterally on the two slide rods 21. The adjustment mechanism 2 also includes a set of electric cylinders 23 installed on the upper side of the orifice seat 11 and located on one side of the sculpted seat 22. The telescopic arm end of the electric cylinder 23 faces the sculpted seat 22 and is connected to it. The extension and retraction of the electric cylinder 23 can drive the sculpted seat 22 to move laterally on the slide rods 21.

[0038] like Figure 5 As shown, a longitudinally movable slide 25 is provided between the inner sides of the U-shaped base 22, and a horizontal plate 24 is provided on the outer side of the slide 25. A set of electric cylinders 28 with telescopic arms facing downward and connected to the horizontal plate 24 is installed on the upper side of the U-shaped base 22. The telescopic electric cylinders 28 drive the horizontal plate 24 to move up and down, while adjusting the height of the slide 25.

[0039] like Figure 2 and Figure 5As shown, a moving groove for longitudinal movement of the slide block 25 is provided on the upper side of the horizontal plate 24. A set of slide rods 29 with longitudinal direction are symmetrically installed between the inner walls of the moving groove, which pass through the slide block 25 and are slidably connected to it. An electric cylinder 27 with telescopic arm end connected to the slide block 25 is installed on the upper side of the horizontal plate 24. When the electric cylinder 27 extends or retracts, it can drive the slide block 25 to move longitudinally on the slide rod 29, thereby adjusting its longitudinal position.

[0040] like Figure 1 , Figure 2 and Figure 6 As shown, a second motor 26 is installed at the center of the upper side of the slide block 25. A fixing mechanism 3 is installed at the drive end of the second motor 26. The fixing mechanism 3 includes a fixing plate 31 located directly below the horizontal plate 24. A U-shaped plate 35 connected to the drive end of the second motor 26 is installed at the center of the upper side of the fixing plate 31. The running second motor 26 drives the fixing plate 31 to rotate through the U-shaped plate 35.

[0041] like Figure 6 As shown, a set of suction cups 32 are symmetrically installed on the lower side of the fixing plate 31, and a negative pressure generator 34 is installed on the upper side of the fixing plate 31. The driving end of the negative pressure generator 34 is equipped with a multi-port pipe 33 that communicates with the two suction cups 32. The upper surface of the waterstop plate is attached to the two suction cups 32, and then the negative pressure generator 34 generates negative pressure in the two suction cups 32 through the multi-port pipe 33, which adsorbs the waterstop plate onto the two suction cups 32.

[0042] It should be noted that the suction cup 32 is made of silicone and has an adaptive air seal ring on the edge. The multi-channel tube 33 integrates a pressure sensor (not shown). When the suction force is lower than the threshold, the negative pressure generator 34 automatically increases the pressure.

[0043] In summary, after attaching the upper surface of the waterstop plate to the two suction cups 32, the negative pressure generator 34 is activated. The generator creates negative pressure inside the suction cups 32 through the multi-port pipe 33, which firmly adheres the waterstop plate to the suction cups 32. Then, the pushing device along the installation seam moves the waterstop plate to be installed to the side of the already installed waterstop plate. If it is observed that the edges of the waterstop plate to be installed and the already installed waterstop plate are not parallel, the motor 26 is activated first to drive the fixing mechanism 3 to rotate, which drives the waterstop plate to rotate synchronously to adjust the edge angle until the edges of the two are completely parallel to the naked eye of the staff.

[0044] After the angle adjustment is completed, the electric cylinder 23 is extended, driving the U-shaped seat 22 to move towards the installed waterstop plate until the adjacent edges of the two waterstop plates overlap from the worker's overhead view. Then, the electric cylinder 27 is extended and retracted, driving the slide 25 to move longitudinally, thereby adjusting the longitudinal position of the waterstop plate on the fixing mechanism 3 until its two side edges are precisely aligned with the corresponding edges of the installed waterstop plate. After the waterstop plate is aligned, the electric cylinder 28 is extended, driving the waterstop plate on the fixing mechanism 3 to move downward until its two side edges are embedded in the two mounting seams. Then, the fixing mechanism 3 is controlled to release the suction fixation of the waterstop plate, and the electric cylinder 28 is shortened, driving the fixing mechanism 3 to rise and reset. This completes the installation of the waterstop plate. After that, the new waterstop plate is fixed on the fixing mechanism 3, and the above operation is repeated for the installation of the next waterstop plate. After the anchoring agent in the mounting seam is completely solidified, the waterstop plate is permanently fixed.

[0045] like Figure 1 , Figure 2 and Figure 7 As shown, the device includes a stirring mechanism 4 for stirring the anchoring agent in the caulking joint. The stirring mechanism 4 includes two sets of extension tubes 42 symmetrically rotated and installed on the lower side of the orifice seat 11. The lower end of the extension tube 42 is equipped with a stirring head 43 connected to it. The two sets of stirring heads 43 are placed into the caulking joints on both sides of the expansion joint beforehand. When the device moves, it drives the stirring heads 43 to move in the caulking joint. The rotating stirring heads 43 are used to stir the anchoring agent that has been injected into the caulking joint, thereby improving the fluidity of the anchoring agent in the corresponding part before caulking and ensuring that the caulking is carried out normally.

[0046] like Figure 7 and Figure 9 As shown, the stirring mechanism 4 also includes two housings 41 mounted on the upper side of the mouth-shaped seat 11 and respectively above a set of corresponding extension tubes 42. A motor 48 with the drive end facing downward is installed inside the housing 41. The upper end of each set of two extension tubes 42 extends into the housing 41 and is equipped with a gear 411. The drive end of the motor 48 is equipped with a gear 412 that meshes with the two gears 411 on the same side. The running motor 48 drives the two gears 411 to rotate through the gear 412, thereby driving the stirring head 43 to rotate through the extension tubes 42.

[0047] like Figure 7 and Figure 8 As shown, friction plates 45 are provided at both ends of the stirring head 43. The stirring mechanism 4 also includes a spreading component. The spreading component drives the two friction plates 45 in each group to move away from each other and press against the inner wall of the fitting seam to stabilize the device.

[0048] like Figure 7 and Figure 8As shown, the unfolding assembly includes a set of pistons 44 symmetrically arranged inside the stirring head 43 and connected to the friction plate 45 on the same side. A spring 46 is connected between the two pistons 44 in the same set. When the two pistons 44 move away from each other, they will cause the two friction plates 45 to move away from each other, and at the same time stretch the piston 47. When the piston 47 rebounds, it will cause the piston 44 to return to its original position, thereby causing the friction plate 45 to return to its original position.

[0049] like Figure 7 and Figure 8 As shown, a number of evenly distributed friction heads 413 are installed on the outer side of the friction plate 45 to enhance the static friction of the surface of the friction plate 45 and improve stability when the friction plate 45 is pressed against the inner wall of the fitting seam.

[0050] like Figure 7 and Figure 8 As shown, a piston 47 adapted to the extension tube 42 is slidably disposed inside the extension tube 42. The extension tube 42 is connected to the stirring head 43 at the center of the side of the stirring head 43. The area below the piston 47 inside the extension tube 42 and the area between the two pistons 44 inside the stirring head 43 form a closed hydraulic chamber. The hydraulic chamber is filled with incompressible hydraulic oil. When the piston 47 descends, it will squeeze the hydraulic oil below it, and use the hydraulic oil to squeeze the two pistons 44 away from each other.

[0051] like Figure 7 and Figure 8 As shown, an extension rod 410 penetrating the outer casing 41 is installed on the upper side of piston 2 47. An electric cylinder 49 connected to the end of the telescopic arm and the two extension rods 410 on the same side is installed on the upper side of the outer casing 41. The telescopic electric cylinder 49 drives piston 2 47 to rise and fall through the extension rod 410.

[0052] It should be noted that in the initial state, the stirring head 43 is in the longitudinal state, the motor 48 is equipped with a photoelectric encoder and a brake, and the controller presets the number of rotations and the stop position to ensure that the stirring head 43 rotates a full number of times each time it rotates. When the stirring head 43 stops, it is still in the longitudinal state, so that the friction plate 45 can abut against the inner wall of the fitting seam.

[0053] The caulking joints are located on both sides of the expansion joints in the underground building, and the distance between the two expansion joints is the same as the width of the waterstop that needs to be installed, so that the waterstop can be caulked in it. At the same time, an anchoring agent is injected into the caulking joints before caulking.

[0054] After the device is used, the four surfaces need to be cleaned to remove any residual anchoring agent and prevent the anchoring agent from solidifying on them for an extended period of time.

[0055] In summary, before operation, the two sets of mixing heads 43 are placed into the caulking joints on both sides of the expansion joint, with the mixing heads 43 positioned on one side of the device's forward direction. Then, the new waterstop plate is installed onto the fixing mechanism 3. When the device moves and the new waterstop plate is moved to the next installation position, the motor 3 48 is started to drive the mixing heads 43 to rotate. The rotating mixing heads 43 are used to mix the anchoring agent that has been injected into the caulking joint, thereby improving the fluidity of the anchoring agent in the corresponding part before the waterstop plate is installed, ensuring the installation effect.

[0056] Before the new waterstop plate is installed, the control cylinder 49 retracts, driving the two pistons 47 downwards via the extension rod 410, creating downward pressure on the hydraulic oil. Under pressure, the hydraulic oil squeezes the inner side of each set of pistons 44, causing them to move away from each other, which in turn causes the two friction plates 45 to move away from each other. Simultaneously, the spring 46 is stretched until the friction plates 45 are tightly pressed against the inner wall of the installation seam. This enhances the stability of the device and effectively prevents displacement due to vibration during subsequent adjustment. After the new waterstop plate is installed, the control cylinder 49 extends, driving the pistons 47 upwards to reset. At the same time, the spring 46 rebounds and retracts, driving the two pistons 44 closer to their initial position, causing the friction plates 45 to detach from the inner wall of the installation seam, releasing the device from its fixed state. Then, the new waterstop plate is installed on the fixing mechanism 3, and the stirring head 43 continues to rotate. Repeating the above operations completes the subsequent waterstop plate installation.

[0057] Beforehand, two sets of mixing heads 43 are placed into the caulking joints on both sides of the expansion joint, with the mixing heads 43 positioned on the side of the device's forward direction. Then, the new waterstop plate is installed on the fixing mechanism 3. When the device moves to move the new waterstop plate to the next installation position, the running motor 3 48 drives the mixing heads 43 to rotate. The rotating mixing heads 43 are used to mix the anchoring agent that has been injected into the caulking joint, thereby improving the fluidity of the anchoring agent in the corresponding part before caulking.

[0058] Before the new waterstop is installed, the electric cylinder 49 shortens and drives the two pistons 47 to descend via the extension rod 410, pressing down the hydraulic oil. The hydraulic oil squeezes the inner surfaces of each set of pistons 44, causing them to move away from each other. This causes the two friction plates 45 to move away from each other while stretching the spring 46 until the friction plates 45 press against the inner wall of the installation seam. This enhances the stability of the device and prevents the device from shifting due to vibration during the subsequent adjustment mechanism operation. After the new waterstop is installed, the electric cylinder 49 extends and drives the pistons 47 to rise. At the same time, the spring 46 shortens and drives the two pistons 44 to move closer to each other until they return to their original positions, so that the friction plates 45 no longer press against the inner wall of the installation seam. This releases the fixation, and then the new waterstop is installed on the fixing mechanism 3. Meanwhile, the stirring head 43 continues to rotate. The operation can be repeated.

[0059] Example 2: Based on Embodiment 1, a U-shaped seat 13 is installed on the upper side of the U-shaped seat 11 on one side of each pulley 12. A vertical screw 14 is rotatably installed between the inner surfaces of the U-shaped seats 13. A threaded seat 15 is threadedly connected to the screw 14 and slidably connected to the inner surface of the U-shaped seat 13. The threaded seat 15 is fixedly connected to the bracket of the adjacent pulley 12. A motor 16 is installed on the upper side of the U-shaped seat 13, with its driving end connected to the end of the screw 14. The running motor 16 drives the screw 14 to rotate, thereby driving the threaded seat 15 to move. The moving threaded seat 15 drives the pulley 12 to rise and fall, thereby adjusting the height of the U-shaped seat 11.

[0060] After aligning the two sets of stirring heads 43 on the device with the two fitting seams on both sides of the expansion joint, all motors 16 run synchronously to drive the screw 14 to rotate, causing the threaded seat 15 to rise on the screw 14. Since the pulley 12 is supported on the building surface, the orifice seat 11 is lowered relative to it, causing the stirring head 43 to descend and extend into the fitting seam. Then, the motors 16 drive the screw 14 in the opposite direction to raise the orifice seat 11, which will then drive the stirring head 43 to move out of the fitting seam.

[0061] A bubble level is installed at the center of the upper side of the U-shaped seat 22. When the construction surface is uneven, the bubble in the bubble level will deviate from the center position, causing the entire device to be tilted. At this time, the motor 16 in the corresponding direction can be started according to the direction of the bubble in the bubble level. After the motor runs, it drives the screw 14 to rotate in the opposite direction, so that the corresponding offset position of the U-shaped seat 11 is raised, thereby adjusting the horizontal state of the U-shaped seat 11. Continue to adjust until the bubble in the bubble level returns to the center position, which means that the U-shaped seat 11 has reached the horizontal state. At this time, the normal installation of the waterstop plate can be carried out.

[0062] This application also discloses a method for embedding waterproofing material in expansion joints of underground buildings, the steps of which are as follows: S1. Pre-equipment: Move the device to one side of the expansion joint and place the two stirring heads 43 into the caulking joint. Specifically, first place the two sets of stirring heads 43 into the caulking joints on both sides of the expansion joint, and position the stirring heads 43 on one side of the device's forward direction. After attaching the upper surface of the waterstop plate to the two suction cups 32, start the negative pressure generator 34. Through the multi-port pipe 33, a negative pressure is formed inside the suction cups 32, which firmly adsorbs the waterstop plate onto the suction cups 32.

[0063] S2. Anchoring agent mixing: The mixing mechanism 4 mixes the anchoring agent in the part to be installed during the movement of the device. Specifically, when the device is moved manually to move the new waterstop to the next installation position, the running motor 3 48 drives the mixing head 43 to rotate. The rotating mixing head 43 mixes the anchoring agent that has been injected into the installation seam, improving the fluidity of the anchoring agent in the corresponding part before installation.

[0064] S3. The device is fixed. The friction plate 45 is pressed against the inner wall of the fitting seam using the unfolding component in the stirring mechanism 4. Specifically, before the new waterstop is installed, the electric cylinder 49 is shortened and the two pistons 47 are lowered through the extension rod 410. The hydraulic oil is pressed down and the inner side of each set of pistons 44 is squeezed by the hydraulic oil to make them move away from each other. At the same time, the two friction plates 45 are pulled away from each other and the spring 46 is stretched until the friction plate 45 is pressed against the inner wall of the fitting seam, which enhances the stability of the device.

[0065] S4. Waterstop plate adjustment: The position of the waterstop plate is finely adjusted by adjusting mechanism 2 to align it with the already installed waterstop plate. Specifically, motor 26 is started to drive the fixing mechanism 3 to rotate, which in turn drives the waterstop plate to rotate synchronously to adjust the edge angle until the edges of the two plates are completely parallel to the naked eye. After the angle adjustment is completed, the electric cylinder 23 is extended to move the U-shaped seat 22 toward the installed waterstop plate until the adjacent edges of the two waterstop plates overlap from the worker's top view. Then, the electric cylinder 27 is operated to extend and retract, driving the slide 25 to move longitudinally, thereby adjusting the longitudinal position of the waterstop plate on the fixing mechanism 3 until its two side edges are precisely aligned with the corresponding edges of the installed waterstop plate. After the waterstop plate is aligned, the waterstop plate alignment is completed.

[0066] S5. Waterstop Plate Installation: After the position adjustment is completed, the new waterstop plate is installed. Specifically, after the waterstop plate is aligned, the electric cylinder 28 is extended to move the waterstop plate on the fixing mechanism 3 downwards until its two side edges are embedded in the two installation seams and contact the bottom of the seams. At this time, the installation is completed and the old and new waterstop plates are connected. Then, the fixing mechanism 3 is controlled to release the suction fixation of the waterstop plate, and the electric cylinder 28 is shortened to move the fixing mechanism 3 upwards to reset. The electric cylinder 49 is extended to move the piston 47 upwards, and at the same time, the spring 46 is shortened to move the two pistons 44 closer to each other until the position is restored, so that the friction plate 45 no longer abuts against the inner wall of the installation seam, and the fixation is released. Then, the new waterstop plate is installed on the fixing mechanism 3, and the stirring head 43 continues to rotate. The operation is repeated.
