Description

Technical Field

[0001] This invention relates to the field of nuclear power engineering construction, and in particular to a concrete surface water spraying and leveling device. Background Technology

[0002] Concrete is an indispensable building material in modern construction, especially high-strength concrete, which has the characteristic of maintaining structural stability under high temperature, high pressure and radiation environments, making it an essential building material for nuclear power projects.

[0003] Related technology can be found in Chinese Patent No. CN113431238B, which discloses a construction method for stainless steel hot cell floor slabs in nuclear engineering, belonging to the field of nuclear engineering construction technology. By dividing the hot cell floor slab construction into two stages, the stainless steel clad shell is installed as a whole on several channel steel supports pre-embedded in the first concrete pour after the first pour. After passing the water pressure test, a second pressure grouting is performed to form a second grouting layer. This two-stage construction of the floor slab facilitates the work of workers tying the floor slab reinforcement, helps ensure the installation quality of the stainless steel clad shell, and protects the pre-embedded components from damage. The bottom support system of the floor slab consists of concrete walls, horizontal bars and vertical shear braces between the walls, and the panel, forming a stable support system that ensures the engineering quality of the stainless steel clad shell and the floor slab. This solves the problem of difficult operations in confined spaces, reduces personnel input, and significantly shortens the construction period.

[0004] Regarding the aforementioned technologies, water-reducing agents need to be added during the concrete preparation process. With the continuous research and iteration of water-reducing agent technology, its water retention and cohesive properties have improved, and the post-bleeding rate has been greatly reduced. This makes it more difficult to finish the concrete surface slab, reduces the finishing efficiency, and easily affects the subsequent construction progress. Summary of the Invention

[0005] To improve the finishing efficiency of concrete after pouring, this application provides a concrete surface water spraying and leveling device.

[0006] In the first aspect, this application provides a concrete surface water spraying and leveling device, which adopts the following technical solution:

[0007] A concrete surface watering and leveling device includes a sprinkler and a support. The support is located at the upper end of the sprinkler to support and move it. A drive component is located at the lower end of the support to move the support. The sprinkler includes a water outlet pipe and a mounting plate. The mounting plate is located on the side of the support away from the drive component. The support has a support arm for supporting the mounting plate. The water outlet pipe is horizontally fixed to the lower end of the mounting plate, and several water spray nozzles are connected to the lower end of the water outlet pipe along its length. Several rakes are also provided at the lower end of the mounting plate. The rakes are vertically retractable. All the rods are located on the side of the water outlet pipe away from the drive unit, and several rake rods are evenly arranged along the length of the water outlet pipe. The frame is equipped with a film placement frame, which is located above the drive unit. The film placement frame holds the film rolls used to cover the concrete, and the support is rotatably connected to several traction rollers for driving the film rolls to unwind. A film unwinding roller is rotatably connected to the side of the frame near the rake rods. After the film rolls are unwound, they form a film strip. The film strip is wound around the film unwinding roller from top to bottom and laid away from the water outlet pipe. A scraper is provided between the film unwinding roller and the rake rods to smooth the surface of the concrete.

[0008] By adopting the above technical solution, the support frame travels on the concrete surface via a drive mechanism. The support frame is supported by a support arm and mounting plate for the water outlet pipe. As the support frame moves, the rake and water outlet pipe move synchronously with it. The rake initially flattens the upper surface of the concrete. Water is supplied to the water outlet pipe through an external water supply system, allowing the water to be sprayed onto the concrete surface from the sprinkler head. The support frame continues to move, and a scraper further flattens the water-sprayed concrete. The support frame supports the film roll via a film placement frame, and a traction roller unwinds the film roll to form a film strip. This film strip is wrapped around the unloading roller and placed close to the concrete surface. As the unloading roller rotates, the film is laid onto the concrete surface after the second leveling. By spraying water and flattening the concrete, the surface finishing effect is improved, and no manual labor is required for watering and flattening, thus improving construction efficiency.

[0009] Optionally, the driving component includes two moving belts and a fixed frame. The two moving belts are located on both sides of the support along the length direction. The support is fixed with a drive motor for driving the moving belts to rotate. The fixed frame is located between the two moving belts and is fixedly connected to the support. A person-carrying plate is provided at the lower end of the fixed frame, and the person-carrying plate extends away from the water outlet pipe.

[0010] By adopting the above technical solution, under the support of the bracket, two moving belts are driven by a drive motor to rotate. The lower end face of the moving belt contacts the upper surface of the concrete. When the moving belt rotates, it drives the bracket to move along the upper surface of the concrete. The moving belt helps to increase the contact area with the concrete, reducing the marks left on the upper surface of the concrete when the bracket moves. The personnel board is used to support the operators, reducing the amount of work required by the workers.

[0011] Optionally, the support arm is hinged vertically to the bracket, the bracket is provided with a power component for driving the support arm to rotate vertically, the mounting plate is located on the side of the support arm away from the bracket, and a rotating rod is fixed at the upper end of the mounting plate. The rotating rod is arranged parallel to the water outlet pipe, and the rotating rod passes through the mounting plate and is rotatably connected to the mounting arm around its own axis. The bracket is fixed with a positioning rod corresponding to the rotating rod. A sprocket one is coaxially fixed to the positioning rod, and a sprocket two corresponding to the sprocket one is coaxially fixed to the rotating rod. A ring chain meshes between the sprocket one and the sprocket two.

[0012] By adopting the above technical solution, when the rake arm is not in operation, the power component drives the support arm to rotate, causing the support arm to move the mounting plate vertically. The positioning rod and sprocket one are both fixed. When the support arm rotates, it drives sprocket two to rotate around the axis of sprocket one. Under the connection of the ring chain, when the support arm drives sprocket two to rotate, sprocket two drives the rotating rod to rotate around its own axis, keeping the rake arm vertical and improving its stability when entering or leaving the concrete.

[0013] Optionally, the film placement frame includes two mounting rollers, two support blocks, and a drive roller. The two support blocks are located on both sides of the support along its length and are slidably connected to the support vertically. The support is rotatably connected to an adjusting rod for moving the support blocks. The mounting rollers are arranged parallel to the water outlet pipe and are rotatably connected to the support blocks. The film roll is sleeved on the outside of the mounting rollers and in contact with them. The drive roller is located at the upper end of the mounting rollers and is rotatably connected to the support around its own axis. The drive roller is parallel to the mounting rollers. The support is equipped with a rotary motor for driving the drive roller to rotate.

[0014] By adopting the above technical solution, the bracket supports the support block through the adjusting rod, and it is easy to adjust the position of the support block vertically. The support block supports the mounting roller, so that the mounting roller supports the film roll. The active roller and the mounting roller cooperate to clamp the film roll. Under the action of friction, when the rotary motor drives the active roller to rotate, it drives the film roll to unwind.

[0015] Optionally, the bracket is fixedly connected to an air supply component, which is connected to an air inlet pipe and an air outlet pipe. When the air supply component is working, it drives the gas in the air inlet pipe to flow to the air outlet pipe. The bracket is fixedly connected to a support plate, and the film feeding roller is rotatably connected to the support plate. The support plate has an air intake groove connected to the air inlet pipe on the side near the film feeding roller, and an air outlet connected to the air outlet pipe on the side near the film feeding roller. The air outlet and the air intake groove are arranged opposite each other with the film feeding roller axis as the center, and the air outlet is located at the lower end of the air intake groove. The film feeding roller has several air supply channels corresponding to the air intake groove and the air outlet along the axial direction. When the film feeding roller rotates, it drives the air outlet and the air intake groove to pass through the air supply channels in sequence. The outer circle of the feeding pipe has several through holes connected to the air supply channels along the circumferential direction. The film feeding roller is connected to a traction roller, and when the traction roller rotates, it drives the film feeding roller to rotate.

[0016] By adopting the above technical solution, the air conveying component operates, drawing airflow from the suction groove through the air inlet pipe and delivering the airflow to the air outlet through the exhaust pipe. When any air conveying channel rotates to the upper end of the film-dispensing roller, it connects with the suction groove. Under the action of the through hole, the film-dispensing roller adsorbs the film. When the film-dispensing roller rotates, connecting the air conveying channel with the air outlet, the airflow in the air outlet enters the air conveying channel and is discharged along the through hole, thereby blowing the film onto the concrete surface, which helps to improve the stability of film laying.

[0017] Optionally, the support plate is rotatably connected to a swing plate in the vertical direction. An elastic element is provided between the swing plate and the support plate. In the natural state of the elastic element, the swing plate is close to the water outlet pipe and tilted upward. The scraper is located on the side of the swing plate away from the support plate and is hinged to the swing plate in the vertical direction. An elastic element is provided between the swing plate and the scraper. When both the elastic element and the elastic element are in the natural state, the lower end face of the scraper is lower than the lower end face of the unloading roll. A collision wheel is rotatably connected to the end of the swing plate away from the support plate in the vertical direction. The diameter of the collision wheel is larger than the width of the swing plate.

[0018] By adopting the above technical solution, when both elastic element one and elastic element two are in their natural state, the scraper is in working state. When the scraper collides with other objects, it can be flipped and avoided by the connecting action of the swing plate. When there is a protruding wall at the edge of the construction site after watering and leveling, after the support arm drives the rake to retract, the swing plate collides with the protruding wall through the collision wheel. Under the guidance of the collision wheel, the swing plate drives the scraper to flip and avoid the protruding wall, so that the paving roller is close to the protruding wall, which is conducive to improving the paving effect.

[0019] Optionally, a straight plate is fixedly connected to one end of the support plate near the water outlet pipe. The straight plate is horizontally arranged. A cutting plate is provided between the scraper and the film feeding roller. The film strip passes through the cutting plate and the film feeding roller. The cutting plate is slidably connected to the straight plate in the direction close to or away from the film feeding roller. An elastic element three is provided between the straight plate and the cutting plate. In its natural state, the elastic element three drives the cutting plate away from the film feeding roller. A stop block is fixedly connected to the upper end of the cutting plate. When the swing plate swings upward, it drives the scraper to approach the stop block.

[0020] By adopting the above technical solution, in the initial state, the cutting plate moves away from the film feeding roller under the action of the elastic element three. When the swing arm flips, it drives the scraper to contact the stop block. Then, under the support of the straight plate, it pushes the cutting plate closer to the film, so that the cutting plate and the film feeding roller cooperate to cut the film, improving the convenience of cutting the film.

[0021] Secondly, this application provides a construction method for a concrete surface water spraying and leveling device, comprising the following steps:

[0022] Pouring: The process of pouring concrete grout into the pre-designated construction location;

[0023] Vibration: An immersion vibrator is selected and used to vibrate the concrete slurry to remove air bubbles inside the concrete.

[0024] Leveling: The drive support moves and the rake rod is inserted into the concrete. When the support moves, the rake rod is used to level the surface of the concrete.

[0025] Sprinkling water; water is supplied through the water pipe and sprayed onto the leveled concrete surface through the sprinkler head;

[0026] Leveling: The support continues to move, using a scraper to level the surface of the sprayed concrete.

[0027] Film covering: The film is applied to the flattened concrete surface using a film-spreading roller.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] The support frame moves across the concrete surface via a drive mechanism. The support frame is supported by a support arm and mounting plate, which in turn supports the water outlet pipe. As the support frame moves, the rake and water outlet pipe move synchronously with it. The rake initially flattens the upper surface of the concrete. Water is supplied to the water outlet pipe via an external water supply system, allowing the water to be sprayed onto the concrete surface from the sprinkler head. The support frame continues to move, further flattening the concrete a second time using a scraper. The support frame supports the film roll via a film placement frame, and a traction roller unwinds the film roll to form a film strip. This film strip is wrapped around a release roller and placed close to the concrete surface. As the release roller rotates, the film is laid onto the concrete surface after the second leveling. By spraying water and flattening the concrete, the surface finish is improved, and this watering and flattening process requires no manual intervention, increasing construction efficiency.

[0030] Supported by the scaffold, two moving belts are driven by a motor to rotate. The lower end of each moving belt contacts the upper surface of the concrete. As the moving belts rotate, they move the scaffold along the upper surface of the concrete. The moving belts increase the contact area with the concrete, reducing the marks left on the concrete surface by the scaffold during movement. The personnel board is used to support the operators, reducing their workload. Attached Figure Description

Detailed Implementation

[0037] The present application will be further described in detail below with reference to all the accompanying drawings.

[0038] This application discloses a concrete surface water spraying and leveling device. Example

[0039] Reference Figure 1 and Figure 2 A concrete surface watering and leveling device includes a support frame 1 and a sprinkler. A driving component is located at the lower end of the support frame 1, comprising two moving belts 31 and a fixed frame 32. The two moving belts 31 are located on opposite sides of the support frame 1 along its length. Each moving belt 31 includes an annular belt and rotating rollers. The rotating rollers are horizontally positioned and rotatably connected to the support frame 1 around their own axis. A drive motor 14 is fixedly connected to the support frame 1. The output shaft of the drive motor 14 passes through the support frame 1 and is coaxially fixed to any rotating roller. Multiple rotating rollers are arranged horizontally in the radial direction. The annular belt is sleeved on the outside of multiple rotating rollers and is tumbledly connected to them. When the rotating rollers rotate, they drive the annular belts to rotate.

[0040] Reference Figure 1 and Figure 2 During construction, the support frame 1 is placed on the vibrated concrete surface. Two moving belts 31 support the support frame 1. The rotating annular belts move the support frame 1, and their smooth outer surface helps minimize marks left by the support frame 1 on the concrete surface. A fixed frame 32 is located between the two moving belts 31 and is fixedly connected to the support frame 1. A rotating roller is rotatably connected to the fixed frame 32, which supports the roller. A personnel platform 321 is fixedly connected to one side of the fixed frame 32. Operators stand on the personnel platform 321 during construction, and the support frame 1 moves, causing the operator to move via the personnel platform 321.

[0041] Reference Figure 1 and Figure 2 The sprinkler includes a water outlet pipe 21 and a mounting plate 22. The mounting plate 22 is located on the side of the bracket 1 away from the passenger board 321. A support arm 11 is provided between the bracket 1 and the mounting plate 22. A positioning rod 15 corresponding to the support arm 11 is fixedly connected to the bracket 1. The positioning rod 15 is parallel to the rotating rod 221 and passes through the support arm 11 and is rotatably connected to the support arm 11. The mounting plate 22 is located on the side of the support arm 11 away from the positioning rod 15, and a rotating rod 221 parallel to the positioning rod 15 is fixedly connected to the mounting plate 22. The rotating rod 221 passes through the support arm 11 and is rotatably connected to the support arm 11.

[0042] Reference Figure 1 and Figure 2 The bracket 1 is equipped with a power component 111 for rotating the support arm 11. The power component 111 is a hydraulic cylinder, which is hinged vertically to the bracket 1, and its output end is rotatably connected to the support arm 11. When the output end of the hydraulic cylinder moves, it drives the support arm 11 to swing vertically, causing the support arm 11 to move the mounting plate 22. The water outlet pipe 21 is fixed to the end of the mounting plate 22 and moves synchronously with the mounting plate 22, and is arranged parallel to the rotating roller. The water outlet pipe 21 is used to connect to an external water supply system, such as a water tank or tap water pipe. Multiple sprinkler heads 211 are installed along the length of the lower end of the water outlet pipe 21. When the external water supply system delivers water to the water outlet pipe 21, the water is evenly sprayed from the sprinkler heads 211.

[0043] Reference Figure 1 and Figure 2 Multiple rakes 23 are fixedly connected to the lower end of the mounting plate 22. The rakes 23 are located on the side of the water outlet pipe 21 away from the man-carrying plate 321, and the multiple rakes 23 are evenly arranged along the length of the mounting plate 22. In the initial state, the lower ends of the rakes 23 are inserted into the concrete. When the drive unit moves the bracket 1, the rakes 23 initially flatten the upper surface of the concrete. After the initial flattening is completed, the water outlet pipe 21 sprays water onto the upper surface of the concrete through the sprinkler head 211. The positioning rod 15 is coaxially fixed with a sprocket 151, and the rotating rod 221 is coaxially fixed with a sprocket 151 that is adapted to the sprocket 222. A ring chain 152 meshes between the sprocket 151 and the sprocket 222. When the support arm 11 drives the sprocket 222 to move through the rotating rod 221, the sprocket 222 drives the rotating rod 221 to rotate around its own axis, so that the rake rod 23 remains vertical during the rotation of the support arm 11, which helps to improve the stability of the rake rod 23 when it enters or leaves the concrete.

[0044] Reference Figure 1 and Figure 2The frame also includes a film placement rack, which comprises two mounting rollers 41, two support blocks 42, and a drive roller 43. The two support blocks 42 are located at both ends of the frame along its length and are slidably connected to the support 1 vertically. The support 1 is vertically provided with an adjusting rod 44, which is rotatably connected to the support 1 around its own axis. The adjusting rod 44 has an external thread and passes through and is threadedly connected to the support rod. When the adjusting rod 44 is rotated, it causes the support blocks 42 to move vertically.

[0045] Reference Figure 1 and Figure 2 The mounting roller 41 is located on one side of the two support blocks 42 that are close to each other, and the mounting roller 41 is arranged parallel to the water outlet pipe 21. A round rod is slidably connected to the support block 42 along the axis of the mounting roller 41. The mounting roller 41 is sleeved on the outside of the round rod and rotatably connected to the round rod. A return spring 45 is provided between the round rod and the mounting roller 41. One end of the return spring 45 is fixedly connected to the support block 42, and the other end is fixedly connected to the round rod. In its natural state, the return spring 45 pushes the mounting roller 41 away from the support block 42.

[0046] Reference Figure 1 and Figure 2 The drive roller 43 is located at the upper end of the two mounting rollers 41 and is rotatably connected to the bracket 1 around its own axis. The bracket 1 is equipped with a rotary motor 46 for driving the drive roller 43 to rotate. When placing the film roll, the mounting roller 41 is pushed towards the support block 42. After the film roll enters between the two mounting rollers 41, the mounting rollers 41 are reset under the action of the return spring 45. At this time, both mounting rollers 41 are located inside the film roll, and the two mounting rollers 41 cooperate to support the film roll. By rotating the adjusting rod 44, the support block 42 drives the mounting roller 41 to move closer to the drive roller 43, thereby making the mounting roller 41 and the drive roller 43 cooperate to clamp and position the film roll. Under the action of friction, when the rotary motor 46 drives the drive roller 43 to rotate, the drive roller 43 drives the film roll to rotate.

[0047] Reference Figure 1 and Figure 2 The support frame 1 is also rotatably connected to multiple traction rollers 12. The multiple traction rollers 12 are all located on the side of the drive roller 43 away from the manned plate 321. One end of the film roll is wound around multiple traction rollers 12 in sequence, so that the traction rollers 12 cooperate to clamp the end of the film roll. The frame is also equipped with an unwinding motor 121 for driving any traction roller 12 to rotate. When the traction roller 12 rotates, it drives the film roll to be continuously unwound.

[0048] Reference Figure 2 and Figure 3Two support plates 16 are fixedly connected to the lower end of the support frame 1. The two support plates 16 are located at both ends of the support frame 1 along its length. The same film-laying roller 5 is rotatably connected between the two support plates 16. The film-laying roller 5 is arranged parallel to the traction roller 12, and the lower end of the film-laying roller 5 is close to the upper surface of the concrete. A pulley assembly is provided between the film-laying roller 5 and the traction roller 12. When the traction roller 12 rotates, it drives the film-laying roller 5 to rotate. The film is wrapped around the film-laying roller 5 from top to bottom and extends towards the direction close to the passenger board 321. When the support frame 1 moves, the film is laid along the travel path.

[0049] Reference Figure 2 and Figure 3 The bracket 1 is also equipped with a scraper 13. Both support plates 16 are vertically rotatably connected to a swing plate 17. The scraper 13 is located on the side of the swing plate 17 away from the support plate 16 and is vertically rotatably connected to the swing plate 17. An elastic element 171, a torsion spring, is provided between the swing plate 17 and the support plate 16. One end of the torsion spring is fixedly connected to the support plate 16, and the other end is fixedly connected to the swing plate 17. The support plate 16 is also fixedly connected to a stop plate corresponding to the swing plate 17. In its natural state, the lower end face of the support plate 16 abuts against the upper end face of the stop plate. At this time, the swing plate 17 moves closer to the outlet pipe 21 and is tilted upwards.

[0050] Reference Figure 2 and Figure 3 An elastic element 172 is provided between the scraper 13 and the swing plate 17. The elastic element 172 is also a torsion spring, with one end fixedly connected to the scraper 13 and the other end fixedly connected to the swing plate 17. When the support plate 16 contacts the stop plate and the elastic element 172 is in its natural state, the scraper 13 is in a vertical state, and the lower end face of the scraper 13 is lower than the lower end face of the film-laying roller 5. When the bracket 1 moves, the scraper 13 performs a secondary leveling of the concrete surface after watering. After the secondary leveling is completed, the film-laying roller 5 lays the film onto the concrete surface.

[0051] Reference Figure 2 and Figure 3 The side of the swing plate 17 away from the support plate 16 is vertically connected to an anti-collision wheel. When there is a protruding wall at the edge of the construction site, when the support 1 travels to the position of the protruding wall, the support arm 11 drives the rake 23 to retract, so that the swing plate 17 collides with the protruding wall through the collision wheel 173. Under the guidance of the collision wheel 173, after the collision wheel 173 contacts the protruding wall, it drives the swing plate 17 to rotate, so that the swing plate 17 drives the scraper 13 to flip and avoid the protruding wall, thereby making the paving roller close to the protruding wall, which is beneficial to improving the paving effect.

[0052] Reference Figure 2 and Figure 3A straight plate 163 is fixedly connected to the side of the support plate 16 away from the manned plate 321. A cutting plate 18 is slidably connected between the two straight plates 163 in the direction of approaching or moving away from the film-feeding roller 5. An elastic element 181 is provided between the cutting plate 18 and the straight plate 163. The elastic element 181 is a spring, with one end fixedly connected to the cutting plate 18 and the other end fixedly connected to the straight plate 163. In its natural state, the elastic element 181 drives the cutting plate 18 away from the film-feeding roller 5.

[0053] Reference Figure 2 and Figure 3 The film passes between the cutting plate 18 and the film feeding roller 5. A stop block 182 is fixedly connected to the upper end of the cutting plate 18. When the swing plate 17 drives the scraper 13 to move vertically, the scraper 13 moves closer to the stop block 182. After the scraper 13 contacts the stop block 182, it pushes the stop block 182 to move, so that the stop block 182 drives the cutting plate 18 closer to the film feeding roller 5, so that the cutting plate 18 and the film feeding roller 5 cooperate to cut the film, thereby completing the film cutting, which is more convenient.

[0054] Reference Figure 2 and Figure 4 The support frame 1 is also equipped with an air supply component 6, which includes a fan and a sealed box. The sealed box is fixedly connected to the support frame 1, and the fan is installed inside the sealed box. The sealed box is connected to an air inlet pipe 61 and an exhaust pipe 62. The fan is located between the air inlet pipe 61 and the exhaust pipe 62. When the fan is working, it drives the airflow in the air inlet pipe 61 to flow towards the exhaust pipe 62. The end face of the support plate 16 that contacts the film feeding roller 5 is provided with an air suction groove 161. The air suction groove 161 is connected to the air inlet pipe 61. When the air inlet pipe 61 is working, it draws in the airflow in the air suction groove 161.

[0055] Reference Figure 4 and Figure 5 The support plate 16 has an air outlet 162 on the end face of the air intake groove 161. The exhaust pipe 62 is connected to the air outlet 162. The air outlet 162 is located below the air intake groove 161. Both the air intake groove 161 and the air outlet 162 are directly opposite the end face of the film feeding roller 5 along its length. The film feeding roller 5 has multiple air channels 51 along its axial direction. The multiple air channels 51 are evenly arranged around the circumference of the film feeding roller 5. The film feeding roller 5 also has multiple through holes 52 along its circumference that communicate with the air channels 51. The through holes 52 are arranged along the length of the film feeding roller 5. For any air channel 51, when it moves to the upper end of the film feeding roller 5, it communicates with the air intake groove 161. At this time, the air intake groove 161 draws in external airflow through the air channel 51 and the corresponding through hole 52, and adsorbs the cut film. When the film feeding roller 5 rotates, it drives the film to move.

[0056] Reference Figure 4 and Figure 5When the air delivery channel 51 moves to the lower end of the film-laying roller 5, it connects with the air outlet 162. The airflow in the exhaust pipe 62 enters the air delivery channel 51 along the air outlet 162 and is discharged from the through hole 52, thereby pushing the film to separate from the film-laying roller 5. The airflow pushes the film to adhere to the concrete surface, which is beneficial to further improve the film laying effect.

[0057] The implementation principle of the concrete surface water spraying and leveling device in this embodiment is as follows: A ring belt drives the support 1 to move, increasing the contact area between the support 1 and the concrete. As the support 1 moves, the rake 23 and water outlet pipe 21 move synchronously with it. The rake 23 initially levels the upper surface of the concrete. Then, an external water supply system delivers water to the water outlet pipe 21, which sprays water from the sprinkler head 211 onto the concrete surface. After watering, a scraper 13 levels the watered concrete a second time. Finally, a film is applied to the concrete surface using a film-laying roller 5. By watering, leveling, and applying a film to the concrete, the surface finishing effect is improved. Furthermore, watering and leveling do not require manual labor, thus improving construction efficiency.

[0058] This application also discloses a construction method for a concrete surface water spraying and leveling device, including the following steps:

[0059] Pouring: The process of pouring concrete grout into the pre-designated construction location;

[0060] Vibration: An immersion vibrator is selected and used to vibrate the concrete slurry to remove air bubbles inside the concrete.

[0061] Leveling: Drive the support 1 to move and insert the rake 23 into the concrete. When the support 1 moves, the rake 23 will level the upper surface of the concrete.

[0062] Sprinkling water; water is supplied to the outlet pipe 21 and sprinkled onto the flattened concrete surface through the sprinkler head 211.

[0063] Leveling: The support 1 continues to move, and the scraper 13 is used to level the surface of the sprayed concrete.

[0064] Film covering: The film is covered onto the flattened concrete surface by the film-spreading roller 5.

[0065] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
