Description

Technical Field

[0001] The present invention relates to the technical field of pouring construction equipment. More specifically, the present invention relates to a dam pouring construction device. Background Art

[0002] In the field of water conservancy projects, as the core structure for flood control, water storage, and water resource regulation, the structural stability and durability of dams are directly related to project safety. In traditional concrete dam construction, to control the cracking risk of mass concrete caused by temperature changes, shrinkage, and creep, a layered and segmented pouring process is generally adopted, and expansion joints or induced joints are preset between adjacent pouring blocks. The formation of such joints usually depends on an embedded formwork system: during construction, metal or plastic formwork is buried in the concrete, and after the concrete initial sets, the formwork is removed by external force to form continuous joints. The prior art uses mechanical claws to remove the formwork, but during the grasping process, the formwork is prone to deformation and jamming under multi-directional uneven stress, resulting in a sharp increase in the formwork removal resistance, and local stress concentration is likely to cause the concrete at the edge of the formwork to crack. Summary of the Invention

[0003] An object of the present invention is to provide a dam pouring construction device that separates the poured concrete from the formwork by setting vertical cutting blades and horizontal cutting blades. This setting can not only reduce the influence of external forces but also reduce jamming.

A first gear is provided at the end of the threaded adjusting rod. Any two adjacent first gears are meshed through a second gear. A handle is provided on one of the first gears to drive the first gear to rotate.

[0008] Preferably, a plurality of first telescopic motors are provided on the positioning frame. The plurality of first telescopic motors are arranged along the length direction of the driving block. The ends of the output shafts of the first telescopic motors are all connected to the driving block to drive the driving block to move up and down; Two mounting seats that can move horizontally along it are provided on one of the threaded adjusting rods. The two mounting seats are arranged in one-to-one correspondence with the two moving blocks. A fixed rod is provided on the mounting seat. The fixed rod is arranged vertically. The bottom end of the fixed rod passes through the positioning frame and is located below the inclined plate. The fixed rod can move horizontally relative to the positioning frame. A connecting plate is provided at the bottom end of the fixed rod. A pressure sensor is provided on the connecting plate. The pressure sensor is connected to a controller. The pressure sensor corresponds to the top of the inclined plate. When the top of the inclined plate contacts the pressure sensor, the pressure sensor transmits a sensor signal to the controller. The controller receives the sensor signal and sends a shutdown instruction to the plurality of first telescopic motors, and the driving block stops moving downward.

[0009] Preferably, a third slider is provided on the mounting seat, and a third sliding rail is provided on the support frame. The third slider is slidably connected to the third sliding rail to enable the mounting seat to move horizontally along the threaded adjusting rod.

[0010] Preferably, a self-lubricating and wear-resistant coating is applied to the two inclined surfaces of the driving block and the two opposite surfaces of the inclined plate.

[0011] Preferably, two lead screws are vertically arranged on the movable support. A threaded seat capable of moving up and down is arranged on each lead screw. A cross beam is commonly connected between the two threaded seats. Two longitudinal beams are arranged on the cross beam. A plurality of second telescopic motors are arranged on each longitudinal beam. The ends of the second telescopic motors are all connected to the support frame to drive the vertical cutting blade to move downward. Among them, the lead screw is driven to rotate by a rotary motor.

[0012] The present invention further provides a method for separating the formwork of the dam pouring construction device described above, including the following steps: S1. A laser ranging module is installed on the movable support. The movable support is moved to a predetermined position of the dam pouring formwork. The distance between the two formworks is scanned by the laser ranging module to generate distance data and transmit it to the controller. The controller calculates the adjustment amount of the vertical cutting blade according to the distance data, drives the first rotary motor of the bidirectional threaded adjusting rod to operate, and the bidirectional threaded adjusting rod drives the two moving blocks to move away from each other in the horizontal direction, so that the interval between the two vertical cutting blades matches the formwork interval; S2. An infrared position sensor is installed at the bottom of the support frame to detect the relative position between the vertical cutting blade and the bottom of the expansion joint. The second telescopic motor is started to drive the support frame to drive the vertical cutting blade to move vertically downward along the surface of the formwork. When the bottom end of the vertical cutting blade is aligned with the bottom of the expansion joint, the infrared position sensor sends a positioning completion signal to the controller; S3. After receiving the positioning completion signal, the controller starts a plurality of first telescopic motors on the positioning frame to drive the driving block to move downward in the vertical direction, so that the two inclined surfaces at the lower part of the driving block contact the inclined plates of the horizontal cutting blade. During the downward movement of the driving block, through the sliding cooperation between the inclined surface and the inclined plate, the two horizontal cutting blades are synchronously driven to move away from each other along the first slide rail of the positioning plate until the cutting ends of the horizontal cutting blades are inserted into the bottom end of the formwork. When the horizontal cutting blade moves to the preset position, the top of the inclined plate contacts the pressure sensor on the connecting plate. The pressure sensor transmits the contact signal to the controller. After receiving the contact signal, the controller sends a shutdown instruction to the plurality of first telescopic motors to stop the downward movement of the driving block; S4. After receiving the contact signal, the controller simultaneously sends a start instruction to the second telescopic motor to start the second telescopic motor to run in the reverse direction, driving the support frame to drive the vertical cutting blade and the horizontal cutting blade to move upward synchronously, and using the bidirectional cutting action of the vertical cutting blade and the horizontal cutting blade to lift the formwork upward and separate it from the concrete; S5. Then move the dam pouring construction device to the position of the pre-placed formwork, start the first telescopic motor to drive the driving block to move upward, use the driving part to pull the horizontal cutting blade to reset along the first slide rail, and use the laser rangefinder installed at the end of the horizontal cutting blade to monitor the distance between the two horizontal cutting blades in real time. When the distance is less than the preset safety threshold, the first telescopic motor is turned off, and the formwork is separated from the horizontal cutting blade and the vertical cutting blade, and the formwork removal is completed.

[0013] The present invention has at least the following beneficial effects: First, the present invention realizes the separation of the poured concrete from the formwork by setting the vertical cutting blade and the horizontal cutting blade. This setting can not only reduce the influence of external forces, but also reduce jamming. The present invention realizes the separation of the poured concrete from the surface of the formwork by setting the vertical cutting blade, and realizes the separation of the bottom end of the formwork by setting the horizontal cutting blade. The vertical cutting blade and the horizontal cutting blade support the formwork to move the formwork upward. The present invention can adjust the distance between the two vertical cutting blades, which is convenient for adjusting according to the thickness of the formwork and the width of the expansion joint, so as to improve the application range of the dam pouring construction device. By setting two horizontally movable horizontal cutting blades, it is convenient to adjust the horizontal cutting blade according to the position of the vertical cutting blade. By setting the driving block, the driving part, and the inclined plate, the horizontal cutting blade is driven to move in the horizontal direction. The inclined plate of the horizontal cutting blade is closely attached to the inclined surface of the driving block to ensure the synchronization of the two-way cutting.

[0014] Second, the present invention is provided with a telescopic rod. On the one hand, the telescopic rod is used to support the inclined plate to improve the stability of the inclined plate. On the other hand, by setting the second spring, the second spring and the driving part cooperate with each other, which is beneficial to the reset of the horizontal cutting blade and improves the construction efficiency.

[0015] Third, the present invention limits the moving distance of the inclined plate (limits the horizontal moving distance of the horizontal cutting blade) by setting the connecting plate, avoids the moving distance of the horizontal cutting blade exceeding the vertical cutting blade, and realizes the protection of the first telescopic motor on the other hand.

[0016] Fourth, through the collaborative innovation of the two-way composite cutting mechanism and the intelligent sensing system, the present invention significantly improves the formwork separation efficiency and quality. The adaptive spacing control technology that combines laser ranging and two-way threaded adjusting rod linkage is adopted to realize the 1-second-level dynamic matching of the formwork spacing, and the operation efficiency is increased by more than 47% compared with the traditional method. Combining infrared positioning and pressure sensing double verification, the cutting positioning accuracy is controlled within ±1mm, and the damage rate of the concrete structure integrity is less than 0.5%. The innovative design of the inclined surface driving horizontal blade mechanism, under the guarantee of the pressure feedback mechanism, makes the blade insertion depth error ≤0.5mm, and at the same time reduces the adhesion resistance by 60% through the two-way cutting synchronization improvement technology.

[0017] Other advantages, objectives, and features of the present invention will be partially reflected by the following description and partially understood by those skilled in the art through the research and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The present invention will be further described in detail below with reference to the accompanying drawings so that those skilled in the art can implement it according to the description in the specification.

[0020] As Figure 1-2 shown, the present invention provides a dam pouring construction device, including: A movable support 1, on which there is a support frame 5 that can slide up and down; Two vertical cutting blades 8, which are arranged on the support frame 5, and the interval between the two vertical cutting blades 8 is adjustable; A horizontal cutting assembly, which includes a positioning frame 12 arranged on the support frame 5, two support plates 13 vertically arranged on the positioning frame 12, a positioning plate 14 is jointly arranged at the lower ends of the two support plates 13, an opening 15 is arranged on the positioning plate 14, and the two support plates 13 are located on both sides of the opening 15. Among them, two horizontally movable cutting blades 18 are arranged on the lower surface of the positioning plate 14, the two horizontally movable cutting blades 18 are arranged in one-to-one correspondence with the two vertical cutting blades 8, and an inclined plate 17 is arranged at the end of the horizontally movable cutting blade 18 located in the opening 15, and the inclined plate 17 passes through the opening 15 and can slide horizontally relative to the opening 15; A driving assembly, which includes a driving block 19 arranged on the positioning frame 12 and capable of moving up and down relative to the positioning frame 12. The lower part of the driving block 19 is two inclined surfaces, and the two inclined surfaces are adapted to the two inclined plates 17 so that the driving block 19 moves downward to drive the horizontally movable cutting blade 18 to move. Among them, a plurality of driving members 20 are arranged on the horizontally movable cutting blade 18, and the plurality of driving members 20 are connected to the bottom end of the driving block 19.

[0021] In this technical solution, a steel structure frame is adopted, and universal wheels with locking functions are installed at the bottom. A hydraulic lifting guide rail is provided in the middle of the support. The support frame 5 is connected to the guide rail through a slider to achieve up and down sliding. The lower ends of the horizontal cutting blade 18 and the vertical cutting blade 8 are flush. Two support plates 13 are vertically fixed on both sides. The lower ends of the support plates 13 are connected to the positioning plate 14 by bolts or welding. The two support plates 13 and the two vertical cutting blades 8 are arranged in parallel one by one. The horizontal cutting blade 18 is horizontally arranged. The two ends of the horizontal cutting blade 18 are flush with the two ends of the positioning plate 14. An inclined plate 17 is welded to the end of the horizontal cutting blade 18. The inclined plate 17 passes through the opening 15 and is located above the positioning plate 14 and is in contact with the inclined surface of the driving block 19. The driving block 19 is a wedge-shaped metal block, and a symmetrical inclined surface (matching the angle of the inclined plate 17) is machined at the lower part, and the top is connected to the piston rod of the hydraulic cylinder. The hydraulic cylinder is fixed on the fixed seat at the top of the positioning frame 12, and the lifting of the piston rod is controlled by a solenoid valve. When the driving block 19 moves downward, the inclined surface presses the inclined plate 17 to slide outward, driving the horizontal blade to move away from each other. When the driving block 19 moves upward, the driving block 19 pulls the horizontal cutting blade to reset through the driving member 20. The driving member 20 is a steel wire rope or a connecting rod. When the driving member 20 is a steel wire rope, one end of the steel wire rope is fixedly connected to the driving block, and the other end is connected to the horizontal cutting blade 18. When the driving member 20 is a connecting rod, one end of the connecting rod is hinged to the driving block, and the other end is hinged to the horizontal cutting blade.

[0022] During the use process, the two vertical cutting blades 8 (the two vertical cutting blades 8 respectively correspond to the opposite surfaces of the two templates) are adjusted according to the distance between the two templates at the expansion joint. The distance between the horizontal cutting blade 18 and the corresponding vertical cutting blade 8 is adjusted to be slightly greater than the thickness of the template. Then, the support frame 5 is moved downward. The support frame 5 drives the vertical cutting blade to move downward along the surface of the template. When the lower end of the vertical cutting blade 8 is flush with the lower end of the template, the driving block 19 is moved downward. The driving block 19 contacts the inclined plate 17, and the inclined plate 17 drives the horizontal cutting blade 18 to cut along the lower end of the template. After the cutting is completed, the support frame 5 is moved upward. Under the action of the horizontal cutting blade 18 and the vertical cutting blade 8, the template moves upward. Then, the horizontal cutting blade 18 is moved to separate the template from the horizontal cutting blade 18. Finally, asphalt hemp yarn is poured into the expansion joint and tamped tightly.

[0023] With this technical solution, the present invention separates the cast concrete from the formwork by setting up the vertical cutting blade 8 and the horizontal cutting blade 18. This setting can not only reduce the influence of external forces but also reduce jamming. The present invention separates the cast concrete from the surface of the formwork by setting up the vertical cutting blade 8, and separates the bottom end of the formwork by setting up the horizontal cutting blade 18. Moreover, the vertical cutting blade 8 and the horizontal cutting blade 18 support the formwork to move the formwork upward. The present invention can adjust the distance between the two vertical cutting blades, which is convenient for adjusting according to the thickness of the formwork and the width of the expansion joint, so as to improve the application range of the dam pouring construction device. By setting two horizontally cutting blades 18 that can move relative to each other, it is convenient for the horizontal cutting blade 18 to be adjusted according to the position of the vertical cutting blade 8. By setting the driving block 19, the driving member 20, and the inclined plate 17, the horizontal cutting blade 18 is driven to move in the horizontal direction. The inclined plate 17 of the horizontal cutting blade 18 is closely attached to the inclined surface of the driving block 19 to ensure the synchronism of bidirectional cutting.

[0024] In another technical solution, two pairs of first slide rails are provided on the positioning plate 14 (two pairs of parallel first slide rails are machined on the lower surface of the positioning plate 14 (the material is quenched steel)). The two pairs of first slide rails are arranged in one-to-one correspondence with the two horizontal cutting blades 18. Two first sliders are welded on the horizontal cutting blade 18, and the two first sliders are slidably connected to the corresponding first slide rails (the two first slide rails in each pair of first slide rails are respectively located on both sides of the opening 15). A limit baffle is installed on the outer side of the first slider to prevent the blade from disengaging from the first slide rail when moving. The inclined angle between the inclined surface of the lower part of the driving block 19 and the inclined plate 17 is 45°. When the driving block 19 moves downward, the inclined surface presses the inclined plate 17 to slide outward, driving the horizontal cutting blade 18 to move away from each other along the first slide rail. When the driving block 19 moves upward, the driving member 20 pulls the blade to reset. With this technical solution, the present invention realizes the relative movement between the horizontal cutting blade 18 and the positioning plate 14 by setting the first slide rail and the second slider.

[0025] In another technical solution, a plurality of telescopic rods 16 are arranged at intervals on the support plate 13. The telescopic rods 16 are horizontally arranged, and the ends of the telescopic rods 16 are connected to the corresponding inclined plates 17 to support the inclined plates 17 (the telescopic rods 16 are composed of sleeves, second springs, and rod bodies: the sleeves are welded to the surface of the support plate 13, the second springs are arranged inside, the ends of the second springs are connected to the rod bodies, and the rod bodies are connected to the sides of the inclined plates 17). With this technical solution, on the one hand, the present invention supports the inclined plate 17 by setting the telescopic rod 16 to improve the stability of the inclined plate 17. On the other hand, by setting the second spring, the second spring and the driving member 20 cooperate with each other, which is beneficial to the reset of the horizontal cutting blade 18 and improves the construction efficiency.

[0026] In another technical solution, a plurality of bidirectional threaded adjusting rods 6 are provided on the support frame 5 (each threaded adjusting rod 6 is machined with left- and right-handed symmetric threads, and the threads are symmetric on both sides of the middle of the threaded adjusting rod 6). Two moving blocks 7 are provided on the threaded adjusting rod 6 (the moving block 7 has a threaded hole adapted to the threaded adjusting rod 6, so that the rotation of the threaded adjusting rod 6 drives the moving block 7 to move in the horizontal direction). The top end of the moving block 7 is slidably connected to the support frame 5, and the bottom end of the moving block 7 is connected to the corresponding vertical cutting blade 8 to drive the vertical cutting blade 8 to move in the horizontal direction. A first gear is provided at the end of the threaded adjusting rod 6, and any two adjacent first gears are meshed through a second gear. The number of second gears is determined by the distance between two adjacent first gears. The rotation directions of all the first gears are the same, and one of the first gears is connected to a first rotation motor to drive the first gear to rotate. With this technical solution, the present invention realizes the simultaneous driving of a plurality of threaded adjusting rods 6 to rotate by setting the first gear, so that the two vertical cutting blades 8 move synchronously.

[0027] In another technical solution, a plurality of first telescopic motors are provided on the positioning frame 12. The plurality of first telescopic motors are arranged at intervals along the length direction of the driving block 19. The output shafts of the first telescopic motors extend and contract in the vertical direction, and the ends of the output shafts of the first telescopic motors are all connected to the driving block 19 to drive the driving block 19 to move up and down; One of the threaded adjusting rods 6 is provided with two mounting seats 9 that can move horizontally along it (the mounting seats 9 have threaded holes adapted to the threaded adjusting rods 6, and the positions of the mounting seats 9 are adjusted by rotating the threaded adjusting rods 6). The two mounting seats 9 are arranged in one-to-one correspondence with the two moving blocks 7. A fixing rod 10 is welded or bolted to the mounting seat 9. The fixing rod 10 is arranged vertically. The bottom end of the fixing rod 10 passes through the positioning frame 12 and is located below the inclined plate 17 (the positioning frame 12 has a sliding hole through which the fixing rod 10 can move horizontally). The fixing rod 10 can move horizontally relative to the positioning frame 12. A connecting plate 11 is provided at the bottom end of the fixing rod 10 (the two connecting plates 11 are arranged in parallel in one-to-one correspondence with the two support plates 13) (the support plate 13 is located between the vertical cutting blade 8 and the connecting plate 11). A pressure sensor (model reference DSTP300 pressure transmitter, measuring range 0 - 500N, accuracy ±0.5%FS) is provided on the connecting plate 11. The pressure sensor is connected to a controller. The pressure sensor corresponds to the top of the inclined plate 17. When the top of the inclined plate 17 contacts the pressure sensor, the pressure sensor transmits a sensor signal to the controller. The controller receives the sensor signal and sends a shutdown instruction to multiple first telescopic motors, and the driving block 19 stops moving downward. During use, first, the positions of the vertical cutting blade 8 and the connecting plate 11 are adjusted by rotating the threaded adjusting rod 6. When taking the template, the driving block 19 is driven to move downward by the first telescopic motor. The driving block 19 drives the horizontal cutting blade 18 to move by cooperating with the inclined plate 17. When the horizontal cutting blade 18 moves below the vertical cutting blade 8, at this time, the inclined plate 17 presses the sensor on the connecting plate 11, and the signal is transmitted by the sensor to shut down the first telescopic motor. With this technical solution, the present invention limits the moving distance of the inclined plate 17 (limits the horizontal moving distance of the horizontal cutting blade 18) by setting the connecting plate 11 on the one hand, avoiding the moving distance of the horizontal cutting blade 18 exceeding that of the vertical cutting blade 8, and protecting the first telescopic motor on the other hand.

[0028] In another technical solution, a third slider is provided on the mounting seat 9, and a third sliding rail is provided on the support frame 5. The third slider is slidably connected to the third sliding rail to enable the mounting seat 9 to move horizontally along the threaded adjusting rod 6. With this technical solution, the mounting seat 9 can move horizontally along the threaded adjusting rod 6.

[0029] In another technical solution, a self-lubricating and wear-resistant coating is applied to both inclined surfaces of the driving block 19 and the two opposite surfaces of the inclined plate 17. With this technical solution, it is convenient for the driving block 19 to drive the inclined plate 17 to move, and the service life of the inclined plate 17 can be extended.

[0030] In another technical solution, two lead screws are vertically arranged on the movable support 1. Threaded seats that can move up and down are arranged on the lead screws. A cross beam 2 is commonly connected between the two threaded seats. Two longitudinal beams 3 are arranged on the cross beam 2. A plurality of second telescopic motors 4 are arranged on each longitudinal beam 3. The ends of the second telescopic motors 4 are all connected to the support frame 5 to drive the vertical cutting blade 8 to move downward. Wherein, the lead screw is driven to rotate by a rotating motor. By adopting this technical solution, the present invention realizes driving the support frame 5 to move up and down by arranging the lead screw, the threaded seat and the rotating motor.

[0031] The present invention provides a method for separating formworks of a dam pouring construction device, including the following steps: S1. A laser ranging module is installed on the movable support. The movable support is moved to a predetermined position of the dam pouring formwork. The distance between the two formworks is scanned by the laser ranging module to generate distance data and transmit it to the controller. The controller calculates the adjustment amount of the vertical cutting blade according to the distance data, and drives the first rotating motor of the bidirectional threaded adjusting rod to operate. The bidirectional threaded adjusting rod drives the two moving blocks to move away from each other in the horizontal direction, so that the interval between the two vertical cutting blades matches the formwork interval; S2. An infrared position sensor is installed at the bottom of the support frame to detect the relative position between the vertical cutting blade and the bottom of the expansion joint. The second telescopic motor is started to drive the support frame to drive the vertical cutting blade to vertically move down along the surface of the formwork. When the bottom end of the vertical cutting blade is aligned with the bottom of the expansion joint, the infrared position sensor sends a positioning completion signal to the controller; S3. After the controller receives the positioning completion signal, it starts a plurality of first telescopic motors on the positioning frame to drive the driving block to move down vertically, so that the two inclined surfaces at the lower part of the driving block contact the inclined plates of the horizontal cutting blade. During the downward movement of the driving block, through the sliding cooperation between the inclined surface and the inclined plate, the two horizontal cutting blades are synchronously driven to move away from each other along the first slide rail of the positioning plate until the cutting ends of the horizontal cutting blades are inserted into the bottom end of the formwork. When the horizontal cutting blade moves to the preset position, the top of the inclined plate contacts the pressure sensor on the connecting plate. The pressure sensor transmits the contact signal to the controller. After receiving the contact signal, the controller sends a closing instruction to the plurality of first telescopic motors to stop the downward movement of the driving block; S4. After the controller receives the contact signal, it simultaneously sends a start instruction to the second telescopic motor to start the second telescopic motor to run in the reverse direction, driving the support frame to drive the vertical cutting blade and the horizontal cutting blade to move up synchronously, and separating the formwork from the concrete by the bidirectional cutting action of the vertical cutting blade and the horizontal cutting blade; S5. Then move the dam pouring construction device to the position where the template is to be placed. Start the first telescopic motor to drive the driving block to move upward, and use the driving member to pull the horizontal cutting blade to reset along the first slide rail. The distance between the two horizontal cutting blades is monitored in real time by the laser rangefinder installed at the end of the horizontal cutting blade. When the distance is less than the preset safety threshold, the first telescopic motor is turned off, and the template is separated from the horizontal cutting blade and the vertical cutting blade, and the template removal is completed.

9. The method for separating the formwork of the dam pouring construction device according to any one of claims 1-8, characterized in that, It includes the following steps: S1. A laser ranging module is installed on the movable support. The movable support is moved to a predetermined position of the dam casting formwork. The distance between the two formworks is scanned by the laser ranging module to generate distance data and transmit it to the controller. The controller calculates the adjustment amount of the vertical cutting blade according to the distance data, and operates the first rotating motor of the bidirectional threaded adjusting rod. The bidirectional threaded adjusting rod drives the two moving blocks to move away from each other horizontally, so that the interval between the two vertical cutting blades matches the formwork interval. S2. An infrared position sensor is installed at the bottom of the support frame to detect the relative position between the vertical cutting blade and the bottom of the expansion joint. The second telescopic motor is started to drive the support frame to drive the vertical cutting blade to move vertically downward along the surface of the formwork. When the bottom end of the vertical cutting blade is aligned with the bottom of the expansion joint, the infrared position sensor sends a positioning completion signal to the controller. S3. After the controller receives the positioning completion signal, it starts a plurality of first telescopic motors on the positioning frame to drive the driving block to move downward vertically, so that the two inclined surfaces at the lower part of the driving block are in contact with the inclined plate of the horizontal cutting blade. During the downward movement of the driving block, through the sliding cooperation between the inclined surface and the inclined plate, the two horizontal cutting blades are synchronously driven to move away from each other along the first slide rail of the positioning plate until the cutting ends of the horizontal cutting blades are inserted into the bottom end of the formwork. When the horizontal cutting blade moves to the preset position, the top of the inclined plate contacts the pressure sensor on the connecting plate. The pressure sensor transmits the contact signal to the controller. After receiving the contact signal, the controller sends a closing instruction to the plurality of first telescopic motors to stop the downward movement of the driving block. S4. After the controller receives the contact signal, it simultaneously sends a start instruction to the second telescopic motor to start the second telescopic motor to run in reverse, driving the support frame to drive the vertical cutting blade and the horizontal cutting blade to move upward synchronously, and using the bidirectional cutting action of the vertical cutting blade and the horizontal cutting blade to lift the formwork upward and separate it from the concrete. S5. Then move the dam casting construction device to the position where the formwork is to be placed. Start the first telescopic motor to drive the driving block to move upward, and use the driving member to pull the horizontal cutting blade to reset along the first slide rail. The distance between the two horizontal cutting blades is monitored in real time by the laser rangefinder installed at the end of the horizontal cutting blade. When the distance is less than the preset safety threshold, the first telescopic motor is turned off, and the formwork is separated from the horizontal cutting blade and the vertical cutting blade, and the formwork removal is completed.
