Technical Field
[0001] This invention relates to the field of civil engineering surveying technology, and in particular to a setting-out device and method for civil engineering surveying. Background Technology
[0002] Civil engineering generally refers to civil engineering projects, which encompass the planning, construction, and maintenance of all infrastructure related to water, soil, and culture. Currently, typical civil engineering projects include: housing, roads, waterworks, irrigation systems, flood control, and transportation.
[0003] For example, patent application number CN201820363210.0 discloses "a civil engineering surveying line laying device that improves the convenience of line laying", which includes a first upright, a line laying bucket and a second roller. A connecting shaft is installed inside the first upright, and a winding roller is provided on the outside of the connecting shaft. The winding roller is connected to the connecting shaft through a spiral spring.
[0004] However, when the above-mentioned device is used in rainy weather or after rain, the construction site is often damp and muddy, and the surface of the pull rope is prone to sticking with mud and other debris. If it is wound up directly, the pull rope and mud and debris will be wound into the winding roller at the same time, increasing its weight and making it inconvenient to carry. In addition, the mud and other debris adhering to the surface of the pull rope will also cover the scale on the surface of the pull rope, affecting the workers' observation and measurement values and reducing work efficiency. Summary of the Invention
[0005] The purpose of this invention is to solve the problems in the existing technology where, during rainy days or after rain, the construction site is often damp and muddy, and the surface of the rope is prone to adhering to mud and other debris. Direct winding can easily cause the rope and debris to be rolled into the winding roller, increasing its weight and making it inconvenient to carry. Furthermore, the mud and other debris adhering to the surface of the rope can cover the markings on the rope, affecting the workers' ability to observe and measure values and reducing work efficiency. Therefore, this invention proposes a setting-out device and method for civil engineering surveying.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A surveying and setting-out device for civil engineering includes a wire box, in which a spool is rotatably installed in the middle.

A wire hole is opened on the left side of the wire box corresponding to the measuring rope. A measuring rod is fixedly installed at the other end of the measuring rope. A groove formed by external force compression and deformation is present on the outer side of the measuring rope.

[0008] Preferably, each of the lifting plates has an electric push rod fixedly installed at one of its far ends, and a slider is fixedly installed at the right end of each electric push rod. An arc-shaped groove is opened on the left end of the cleaning ring corresponding to the slider. The right end of the slider is slidably connected to the cleaning ring, and a locking screw is threaded on each slider.
[0009] Preferably, a fixed plate is slidably installed on the right end of the movable plate, the fixed plate is fixedly connected to the left end of the junction box, and a spring four is fixedly installed on the lower end of the movable plate, the lower end of the spring four being fixedly connected to the fixed plate.
[0010] Preferably, an airbag is fixedly installed at the lower end of the movable plate, the lower end of the airbag is fixedly connected to the fixed plate, and a connecting pipe is fixedly connected to the lower end of the airbag. A nozzle ring is fixedly installed at the left end of the cleaning ring corresponding to the measuring rope. The outer sides of the nozzle rings on both sides are respectively connected and fixedly connected to the outlet end of the connecting pipe. A conical rod is fixedly installed at the upper end of the movable plate, and rotating rods are fixedly installed at equal intervals on the outer side of the spool corresponding to the conical rod.
[0011] Preferably, each of the pressure rollers is rotatably mounted with a bracket, and the brackets are fixedly connected to one end of the lifting plate close to each other. The brackets are symmetrically mounted with movable frames on the outer side, and electric push rods are fixedly mounted on the end of the movable frames away from the measuring rope.

[0012] Preferably, a limiting block is fixedly installed on the middle part of the movable frame near the measuring rope, and a limiting strip is fixedly installed on the front and rear sides of the elastic sheet corresponding to the limiting block.

[0015] A method for setting out lines using a civil engineering surveying equipment, the specific steps of which are as follows: Step 1: The staff first fixes the junction box to the ground at the starting point of the measurement location by inserting the grounding pin at the bottom; Step 2: Hold the measuring rod and pull the measuring rope to continuously rotate it and release the line. Step 3: After laying out the lines, insert the measuring rod at the end point of the measurement. Step 4: Rotate the lead screw to bring the connecting plates, guide rods, springs, and cleaning rings on both sides closer together, clamping and fixing the measuring rope.
[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the worker first fixes the junction box to the ground at the starting point of the measurement point by inserting the bottom pin, then holds the measuring rod and pulls the measuring rope to continuously rotate and release the rope from the measuring rod. After the rope is released, the measuring rod is inserted at the end point of the measurement point. The screw is rotated to drive the connecting plates, guide rods, springs and cleaning rings on both sides to move closer to each other, clamping and fixing the measuring rope to prevent the measuring rope between the junction box and the measuring rod from loosening.
[0017] 2. In this invention, after the civil construction survey is completed, the measuring rope is wound up. First, the measuring rod is pulled out of the ground, and then the screw is rotated in the opposite direction to move the connecting plates on both sides away from each other. At this time, the stored force of the first spring will gradually relax, ensuring that the cleaning rings on both sides will not have too much clamping force on the measuring rope due to the large compression force of the first springs on both sides, making it impossible to pass through. Then, the worker rotates the handle to drive the spool to rotate and wind up the measuring rope. The cleaning rings on both sides facilitate the scraping and cleaning of the mud and debris adhering to the outside of the measuring rope, avoiding the situation where a large amount of mud and debris adheres to the outer surface of the measuring rope, causing the scale on the measuring rope to be unclear, thereby improving work efficiency and avoiding the situation where a large amount of mud adheres to the outer surface, increasing the weight of the cable box and making it inconvenient to carry. At the same time, the cleaning rings on both sides apply a certain clamping force to the outer surface of the measuring rope, which can prevent the measuring rope from becoming loose and tangled during winding, which is beneficial for subsequent reuse.
[0018] 3. In this invention, when the spool rotates, it also drives the rotating rod to rotate synchronously. The rotating rod intermittently squeezes the conical rod, causing the conical rod to drive the movable plate to slide down on the fixed plate, compressing the fourth spring. The fourth spring plays a reset role, thereby causing the movable plate to drive the lead screw, the connecting plates on both sides, the guide rod, the first spring, and the cleaning ring to move up and down synchronously. This is beneficial for shaking off the dirt and debris cleaned at the connection between the cleaning ring and the measuring rope, improving the cleaning quality and efficiency of the cleaning ring.
[0019] 4. In this invention, the movable plate will also intermittently squeeze the airbag, causing the gas in the airbag to be ejected through the connecting pipe and nozzle ring. This helps to spray off the mud and debris accumulated at the connection between the cleaning ring and the measuring rope, keeping the measuring rope clean and playing an auxiliary role.
[0020] 5. In this invention, when encountering a depression groove caused by external force squeezing and deformation of the measuring rope surface, first rotate the slider to drive the electric actuator, lifting plate, telescopic rod, and elastic plate to rotate synchronously, so that the elastic plate is located on the side close to the depression groove. After adjustment, rotate the locking screw to lock and fix the slider position. Start the electric actuator to drive the lifting plate, telescopic rod, and elastic plate to move synchronously closer to the depression groove until the elastic plate abuts and fits in the depression groove. As the spool rotates continuously, it drives the measuring rope to be wound up. The elastic plate makes it easy to scrape and clean the mud and debris in the depression groove, avoiding the situation where mud and debris in the dead corners of the depression groove on the surface of the measuring rope cannot be cleaned, ensuring the cleanliness of the measuring rope surface, clear visibility of the scale, and improved work efficiency.
[0021] 6. In this invention, when facing a curved groove, as the electric actuator moves the lifting plate, telescopic rod, and elastic sheet closer to the groove, the middle of the elastic sheet will first contact and abut against the groove. As the lifting plate descends, the telescopic rod adaptively contracts, compressing the spring. The lifting plate also moves the supports and pressure rollers on both sides towards the groove simultaneously. At this time, the pressure rollers will squeeze the sides of the elastic sheet, forcing it to undergo elastic deformation. As the pressure rollers move closer to the groove, the elastic sheet will be continuously squeezed until both sides of the elastic sheet completely fit and wrap around the curved groove. This facilitates the complete cleaning of mud and debris in the curved groove, improving the cleaning quality of mud and debris on the surface of the measuring rope.
[0022] 7. In this invention, after the pressure rollers on both sides have finished squeezing the elastic sheet, the electric actuator is activated to drive the movable frame and the limiting block to move towards the recessed groove simultaneously until the limiting block is engaged in the limiting groove. The limiting block and the limiting groove are designed to limit the elastic sheet that has undergone elastic deformation, preventing the elastic sheet from loosening from the pressure rollers and causing it to fail to fit tightly against the recessed groove. This ensures the quality of cleaning the mud and debris in the recessed groove, maintains the cleanliness of the measuring rope surface, and improves work efficiency.
[0023] 8. In this invention, when the movable frame moves closer to the recessed ditch, it also drives the Z-shaped plate and spring three to move closer to the recessed ditch simultaneously. During the movement of the Z-shaped plate, it will be blocked and squeezed by the inclined plate, thereby driving the Z-shaped plates on both sides to move away from each other and compressing spring three. When the limiting block one is inserted into the limiting groove, the Z-shaped plates on both sides also move between the limiting blocks two on both sides until the Z-shaped plates on both sides move away from each other and abut against the limiting blocks two on both sides and stop. The Z-shaped plate is designed to facilitate the flattening and limiting of the four corners of the elastic sheet, preventing the four corners of the elastic sheet from being lifted or curled due to the squeezing force of the soil and debris when the elastic sheet scrapes the soil and debris in the recessed ditch, thus ensuring the cleaning quality of the soil and debris in the recessed ditch by the elastic sheet.

[0027] Reference Figures 1-11A surveying and setting-out device for civil engineering includes a cable box 1. A spool 2 is rotatably mounted in the center of the cable box 1. The spool 2 is rotatably mounted at the upper center of the cable box 1. A handle is provided at the upper end of the spool 2.

A measuring rod 4 is fixedly mounted at the other end of the measuring rope 3. The outer side of the measuring rope 3 has a groove 301 formed by deformation under external force. A cleaning mechanism is also provided for scraping off dirt and debris adhering to the surface of the measuring rope 3. The cleaning mechanism includes two cleaning rings located on the upper and lower sides of the measuring rope 3. 5. Guide rods 6 are fixedly installed at the opposite ends of the cleaning rings 5. Connecting plates 7 are slidably installed through the opposite ends of the guide rods 6. Springs 8 are sleeved on the outer sides of the guide rods 6. The two ends of the springs 8 are fixedly connected to the cleaning rings 5 and the connecting plates 7 respectively. Lead screws 9 are threaded onto the connecting plates 7 on both sides. Movable plates 10 are rotatably installed on the upper and lower sides of the lead screws 9. The connecting plates 7 are slidably installed on the movable plates 10. Elastic plates 11 are abutting and fitting against the grooves 301 on the front side of the cleaning rings 5 corresponding to the measuring rope 3. Telescopic rods 12 are fixedly installed on the middle of the opposite ends of the elastic plates 11. Each telescopic rod 12 has a lifting plate 13 fixedly installed at one of its opposite ends. A second spring 14 is fitted onto the outer side of each telescopic rod 12, with both ends of the second spring 14 fixedly connected to the elastic plates 11 on both sides and the lifting plate 13, respectively. An electric push rod 15 is fixedly installed at one of the opposite ends of each lifting plate 13. A slider 16 is fixedly installed at the right end of each electric push rod 15. An arc-shaped groove is formed on the left end of the cleaning ring 5 corresponding to the slider 16. The right end of the slider 16 is slidably connected to the cleaning ring 5, and a locking screw 17 is threaded onto each slider 16. A fixed plate 29 is slidably installed on the right end of the movable plate 10. The fixed plate 29 is connected to... The left end of the junction box 1 is fixedly connected, and the lower end of the movable plate 10 is fixedly installed with a spring 30. The lower end of the spring 30 is fixedly connected to the fixed plate 29. The lower end of the movable plate 10 is fixedly installed with an airbag 31. The lower end of the airbag 31 is fixedly connected to the fixed plate 29. The lower end of the airbag 31 is fixedly connected to a connecting pipe 32. The left end of the cleaning ring 5 is fixedly installed with a nozzle ring 33 corresponding to the measuring rope 3. The outer sides of the nozzle rings 33 on both sides are respectively connected to the outlet end of the connecting pipe 32. The upper end of the movable plate 10 is fixedly installed with a conical rod 35, and the outer side of the spool 2 is fixedly installed with rotating rods 34 at equal intervals corresponding to the conical rod 35. During operation, the worker first secures the junction box 1 to the ground at the starting point of the measurement location using the lower insertion pin. Then, holding the measuring rod 4, the worker pulls the measuring rope 3, continuously rotating it to release the rope. After releasing the rope, the worker inserts the measuring rod 4 at the ending point of the measurement location. Rotating the screw 9 causes the connecting plates 7, guide rods 6, springs 8, and cleaning rings 5 on both sides to move closer together, clamping and securing the measuring rope 3 to prevent it from loosening between the junction box 1 and the measuring rod 4. After the civil engineering measurement is completed, the worker retracts the measuring rope 3. First, the measuring rod 4 is pulled out of the ground, then the screw 9 is rotated in the opposite direction to move the connecting plates 7 away from each other. At this time, the stored force of springs 8 gradually relaxes, ensuring that the subsequent retraction of the rope is not caused by excessive compression of springs 8 on both sides, which could lead to loosening of the cleaning rings 5. If the clamping force of the guide ring 5 on the measuring rope 3 is too great and it cannot pass through, the operator will then turn the handle to drive the spool 2 to rotate and wind up the measuring rope 3. The cleaning rings 5 on both sides facilitate the scraping and cleaning of dirt and debris adhering to the outer surface of the measuring rope 3, preventing the markings on the measuring rope 3 from becoming unclear due to a large amount of dirt and debris adhering to its outer surface, thus improving work efficiency and preventing the weight of the wire box 1 from increasing its portability due to a large amount of dirt adhering to it. At the same time, the cleaning rings 5 on both sides apply a certain clamping force to the outer surface of the measuring rope 3, which can prevent the measuring rope 3 from becoming loose and tangled during winding, which is beneficial for subsequent reuse. When the spool 2 rotates, it will also drive the rotating rod 34 to rotate synchronously. The rotating rod 34 intermittently... The conical rod 35 is squeezed, causing the movable plate 10 to slide and descend on the fixed plate 29, compressing the spring 30. The spring 30 then acts as a reset mechanism, causing the movable plate 10 to move synchronously up and down, along with the lead screw 9, the connecting plates 7 on both sides, the guide rod 6, the spring 8, and the cleaning ring 5. This helps to shake off the dirt and debris at the connection between the cleaning ring 5 and the measuring rope 3, improving the cleaning quality and efficiency of the cleaning ring 5. At the same time, the movable plate 10 intermittently squeezes the air bladder 31, causing the gas in the air bladder 31 to be ejected through the connecting pipe 32 and the nozzle ring 33. This helps to spray off the dirt and debris accumulated at the connection between the cleaning ring 5 and the measuring rope 3, keeping the measuring rope 3 clean and providing an auxiliary effect. When the surface of the measuring rope 3 is deformed by external force... When forming the groove 301, first rotate the slider 16 to drive the electric actuator 15, lifting plate 13, telescopic rod 12, and elastic plate 11 to rotate synchronously, so that the elastic plate 11 is located on the side close to the groove 301. After adjustment, rotate the locking screw 17 to lock and fix the position of the slider 16. Start the electric actuator 15 to drive the lifting plate 13, telescopic rod 12, and elastic plate 11 to move towards the groove 301 synchronously until the elastic plate 11 abuts and fits in the groove 301. As the spool 2 rotates continuously, it drives the measuring rope 3 to be wound up. The elastic plate 11 facilitates the scraping and cleaning of mud and debris in the groove 301, avoiding the situation where mud and debris in the dead corners of the groove 301 on the surface of the measuring rope 3 cannot be cleaned, thus ensuring the cleanliness of the surface of the measuring rope 3.The scale is clearly visible, improving work efficiency.
[0028] As an embodiment of the present invention, a bending limiting mechanism for bending and limiting the elastic sheet 11 is also provided. The bending limiting mechanism includes two pressure rollers 18 that are abutting and fitted together with the elastic sheet 11 at opposite ends and symmetrically arranged front and back. A bracket 19 is rotatably mounted on the outer side of each pressure roller 18. The brackets 19 are fixedly connected to the lifting plate 13 at opposite ends. A movable frame 20 is slidably mounted on the outer side of each bracket 19. An electric push rod 21 is fixedly mounted on the end of each movable frame 20 away from the measuring rope 3. The outer side of each electric push rod 21 is fixedly connected to the bracket 19. The movable frame 20 is positioned closer to the measuring rope 3. Limiting blocks 22 are fixedly installed in the middle of each elastic sheet 11. Limiting strips 23 are fixedly installed on the front and rear sides of each elastic sheet 11 corresponding to the limiting blocks 22. Limiting grooves 24 are opened on the end of each limiting strip 23 near the limiting block 22. Z-shaped plates 25 are symmetrically slidably installed on the outer side of the movable frame 20. Springs 26 are fixedly installed on the ends of the Z-shaped plates 25 that are far apart from each other. The other end of the springs 26 is fixedly installed on the movable frame 20. Inclined plates 27 are fixedly installed on the bracket 19 below the Z-shaped plates 25. Limiting blocks 28 are fixedly installed at the four corners of the ends of the elastic sheets 11 that are far apart from each other, corresponding to the Z-shaped plates 25. During operation, when facing the curved groove 301, as the electric actuator 15 drives the lifting plate 13, telescopic rod 12, and elastic plate 11 to continuously approach the groove 301, the middle part of the elastic plate 11 will first contact and abut against the groove 301. As the lifting plate 13 continues to descend, the telescopic rod 12 adaptively retracts, compressing the spring 14. The lifting plate 13 also drives the supports 19 on both sides and the pressure rollers 18 to simultaneously approach the groove 301. At this time, the pressure rollers 18 will squeeze the sides of the elastic plate 11, forcing the elastic plate 11 to undergo elastic deformation. As the pressure rollers 18 continue to descend... As the elastic sheet 11 moves closer to the groove 301, it is continuously compressed until both sides of the elastic sheet 11 completely adhere to and wrap around the curved groove 301. This facilitates the complete cleaning of mud and debris from the curved groove 301, improving the cleaning quality of mud and debris on the surface of the measuring rope 3. After the pressure rollers 18 on both sides have finished compressing the elastic sheet 11, the electric actuator 21 is activated to drive the movable frame 20 and the limiting block 22 to move towards the groove 301 simultaneously until the limiting block 22 engages in the limiting groove 24. The limiting block 22 and the limiting groove 24 facilitate the compression of the elastic sheet 11. The deformable elastic plate 11 is limited to prevent it from loosening from the pressure roller 18, thus ensuring the quality of cleaning the mud and debris in the groove 301, keeping the surface of the measuring rope 3 clean, and improving work efficiency. At the same time, when the movable frame 20 moves closer to the groove 301, it also drives the Z-shaped plate 25 and the spring 26 to move closer to the groove 301. During the movement of the Z-shaped plate 25, it will be blocked and squeezed by the inclined plate 27, thereby causing the two Z-shaped plates 25 on both sides to move away from each other. When the spring 26 is compressed, the Z-shaped plates 25 on both sides move to the space between the two limit blocks 28 on both sides. The Z-shaped plates 25 on both sides move away from each other and stop abutting against the two limit blocks 28 on both sides. The Z-shaped plates 25 are designed to flatten and limit the four corners of the elastic plate 11, preventing the four corners of the elastic plate 11 from being squeezed by the soil and debris when scraping the soil and debris in the recessed trench 301, thus ensuring the cleaning quality of the soil and debris in the recessed trench 301 by the elastic plate 11.
[0029] A method for setting out lines using a civil engineering surveying equipment, the specific steps of which are as follows: Step 1: The staff first fixes the junction box 1 to the ground at the starting point of the measurement location by inserting the grounding pin at the bottom; Step 2: Hold the measuring rod 4 and pull the measuring rope 3 to continuously rotate it off the measuring rod 4 to release the line; Step 3: After laying out the lines, insert measuring rod 4 at the end point of the measurement. Step 4: Rotate the lead screw 9 to bring the connecting plates 7, guide rods 6, springs 8 and cleaning rings 5 closer together, clamping and fixing the measuring rope 3.
[0030] Working principle: In use, the worker first fixes the junction box 1 to the ground at the starting point of the measurement location using the bottom insertion pin. Then, holding the measuring rod 4, the worker pulls the measuring rope 3 to continuously rotate and release the rope. After releasing the rope, the worker inserts the measuring rod 4 at the ending point of the measurement location. Rotating the screw 9 causes the connecting plates 7, guide rods 6, springs 8, and cleaning rings 5 on both sides to move closer together, clamping and fixing the measuring rope 3 to prevent it from loosening between the junction box 1 and the measuring rod 4. After the civil construction measurement is completed, the worker retracts the measuring rope 3. First, the worker pulls the measuring rod 4 out of the ground, then rotates the screw 9 in the opposite direction to move the connecting plates 7 on both sides away from each other. At this time, the stored force of the springs 8 will gradually relax, ensuring that the subsequent retraction of the rope will not be caused by the large compression force of the springs 8 on both sides, resulting in the rope being pulled up too quickly. If the cleaning ring 5 exerts excessive clamping force on the measuring rope 3, preventing it from passing through, the operator can then rotate the handle to rotate the spool 2 and wind up the measuring rope 3. The cleaning rings 5 on both sides facilitate the scraping and cleaning of dirt and debris adhering to the outer surface of the measuring rope 3, preventing unclear markings on the rope 3 due to excessive dirt and debris, thus improving work efficiency and avoiding increased weight and portability of the cable box 1 due to excessive dirt. Simultaneously, the cleaning rings 5 apply a certain clamping force to the outer surface of the measuring rope 3, preventing slackness and tangling during winding, which is beneficial for subsequent reuse. When the spool 2 rotates, it also drives the rotating rod 34 to rotate synchronously. The rotating rod 34 intermittently... The conical rod 35 is squeezed, causing the movable plate 10 to slide and descend on the fixed plate 29, compressing the spring 30. The spring 30 then acts as a reset mechanism, causing the movable plate 10 to move synchronously up and down, along with the lead screw 9, connecting plates 7 on both sides, guide rod 6, spring 8, and cleaning ring 5. This helps to shake off the dirt and debris at the connection between the cleaning ring 5 and the measuring rope 3, improving the cleaning quality and efficiency of the cleaning ring 5. At the same time, the movable plate 10 also intermittently squeezes the air bladder 31, causing the gas in the air bladder 31 to be ejected through the connecting pipe 32 and nozzle ring 33. This helps to spray off the dirt and debris accumulated at the connection between the cleaning ring 5 and the measuring rope 3, keeping the measuring rope 3 clean and providing an auxiliary effect. When the surface of the measuring rope 3 is deformed by external force... When creating the depression 301, first rotate the slider 16 to drive the electric actuator 15, lifting plate 13, telescopic rod 12, and elastic plate 11 to rotate synchronously, so that the elastic plate 11 is located on the side close to the depression 301. After adjustment, rotate the locking screw 17 to lock and fix the position of the slider 16. Start the electric actuator 15 to drive the lifting plate 13, telescopic rod 12, and elastic plate 11 to move towards the depression 301 synchronously until the elastic plate 11 abuts and fits in the depression 301. As the spool 2 rotates continuously, it drives the winding of the measuring rope 3. The elastic plate 11 facilitates the scraping and cleaning of mud and debris in the depression 301, avoiding the situation where mud and debris in the dead corners of the depression 301 on the surface of the measuring rope 3 cannot be cleaned, thus ensuring the cleanliness of the surface of the measuring rope 3.The scale is clearly visible, improving work efficiency. When facing the curved groove 301, as the electric actuator 15 drives the lifting plate 13, telescopic rod 12, and elastic plate 11 to move closer to the groove 301, the middle of the elastic plate 11 will first contact and abut against the groove 301. As the lifting plate 13 continues to descend, the telescopic rod 12 adaptively retracts, compressing the spring 14. The lifting plate 13 will also drive the supports 19 on both sides and the pressure rollers 18 to move closer to the groove 301 simultaneously. At this time, the pressure rollers 18 will squeeze the two sides of the elastic plate 11, forcing the elastic plate 11 to undergo elastic deformation. As the pressure rollers 18 move closer to the recessed groove 301, the elastic sheet 11 is continuously squeezed until both sides of the elastic sheet 11 completely adhere to and wrap around the curved recessed groove 301. This facilitates the complete cleaning of mud and debris in the curved recessed groove 301, improving the cleaning quality of mud and debris on the surface of the measuring rope 3. After the pressure rollers 18 on both sides have finished squeezing the elastic sheet 11, the electric actuator 21 is activated to drive the movable frame 20 and the limiting block 22 to move closer to the recessed groove 301 simultaneously until the limiting block 22 is engaged in the limiting groove 24. The limiting block 22 and the limiting groove 24 are set. 4. This facilitates the limiting of the elastic sheet 11, preventing it from loosening from the pressure roller 18 and thus ensuring its tight fit within the groove 301. This ensures the quality of cleaning the mud and debris in the groove 301, maintains the cleanliness of the measuring rope 3, and improves work efficiency. Simultaneously, when the movable frame 20 approaches the groove 301, it also drives the Z-shaped plate 25 and spring 26 to move towards the groove 301. During the movement of the Z-shaped plate 25, it is blocked and squeezed by the inclined plate 27, causing the Z-shaped plates 25 on both sides to move away from each other. The movement in the direction of separation compresses the spring 26. When the limiting block 22 is inserted into the limiting groove 24, the Z-shaped plates 25 on both sides also move between the limiting blocks 28 on both sides until the Z-shaped plates 25 move away from each other and abut against the limiting blocks 28 on both sides. The Z-shaped plates 25 are designed to flatten and limit the four corners of the elastic plate 11, preventing the four corners of the elastic plate 11 from lifting or warping due to the squeezing force of the soil and debris when scraping the soil and debris in the recessed trench 301. This ensures the cleaning quality of the soil and debris in the recessed trench 301 by the elastic plate 11.
