[0003] The dam panel refers to a continuous and smooth concrete anti-seepage structure layer poured on the upstream side surface of the rock-fill dam, which is the core component of the rock-fill dam, and is equivalent to wearing a layer of anti-seepage armor on the upstream surface of the dam body, which is used to enhance the anti-seepage and waterproof performance of the rock-fill dam and provide long-term stability for the dam structure.
[0004] The dam panel concrete pouring slipform device is an integrated continuous pouring forming equipment specially designed for the upstream slope surface of the concrete panel rock-fill dam, and the core is to realize the efficient and accurate forming of the dam anti-seepage panel through the uniform sliding of the formwork and the synchronous operation of the concrete pouring, which is the core technical equipment for the construction of the panel rock-fill dam.
[0005] In the current prior art, when the concrete poured between the slipform and the dam body is formed, the slipform is moved up to carry out the next pouring, and auxiliary maintenance work is needed for the dam concrete block.

The two rollers are slidably connected to the inside of the two guide rails respectively.
[0019] The beneficial effects of this invention are as follows: 1. The slipform device for pouring concrete for dam face panels of the present invention uses a scraping component to assist in the surface finishing of the formed concrete blocks, while a spraying component sprays curing agent onto the formed concrete blocks through multiple nozzles for curing. In this way, the device can integrate the spraying and pouring functions, and can spray curing agent onto the concrete blocks on the slope in a timely manner. Compared with manually climbing to spray curing agent onto the slope concrete, it saves manpower, improves the spraying effect on the slope concrete, and is more conducive to the curing of concrete.
[0020] 2. The slipform device for pouring concrete for dam face panels described in this invention, when the elastic block contacts the surface of the dam body, the elastic block is restricted by the dam body surface and moves by squeezing the pressure spring on the limiting rod inside the side formwork. The elastic block will always fit between the dam body surface and the side formwork through elastic deformation, thereby sealing and blocking the gap between the side formwork and the dam body surface. This prevents concrete from flowing out from the gap between the two due to the different heights of the dam body surface during pouring, effectively avoiding the problem of too many construction joints caused by segmented pouring and reducing leakage channels.
[0021] 3. The slipform device for pouring concrete for dam face panels described in this invention initially involves a lowering plate that fits against the dam surface, forming a complete pouring cavity in conjunction with the side and top formwork. At the end of pouring, a hydraulic rod moves the lowering plate up to be flush with the top formwork. This allows for leveling of the top of the concrete and, during the first pour, assists the two side and top formwork in their operation, forming a blocking mold on one side of both. This eliminates the need for separate limiting plates on one side of both formwork during the first pour of concrete into the cavity, saving time and manpower.
[0022] 4. The slipform device for pouring concrete for dam face panels described in this invention, when the hydraulic rod drives the support plate to move upward and reset, the support plate drives the rack to move upward. The rack then drives the gear to rotate through tooth meshing, thereby causing the rack to drive the transverse spray box to move downward from above the support plate on one side. This allows the transverse spray box to move closer to the top of the concrete, facilitating spraying operations on the top of the concrete. This avoids the inability to achieve good and uniform spraying of the top of the concrete due to the transverse spray box being set too high.
[0023] 5. In the slipform device for pouring concrete for dam face as described in this invention, when the curing agent is delivered to the transverse spray box through the liquid flow pipe via the feeding device, the transverse spray box will simultaneously deliver the curing agent to the two lateral spray boxes through the cavity pipe. With the restriction of the baffles in the lateral spray boxes, the curing agent will be sprayed out from the nozzles on one side of the two lateral spray boxes, forming a complete annular spray with the transverse spray box to spray the outside of the concrete. Since the height of the formed concrete is different, the baffle can limit the flow rate in the lateral spray box to prevent the curing agent from being sprayed out from the other nozzles on one side of the lateral spray box, thus preventing waste of the curing agent.

Detailed Implementation
[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0028] like Figures 1 to 10As shown in the embodiment of the present invention, a slipform device for pouring concrete for a dam face includes a formwork box 1. A horizontal plate 102 is fixedly installed inside the formwork box 1. Side templates 10 are symmetrically arranged at the bottom of the horizontal plate 102. A top template 11 is arranged between the two side templates 10, forming a mold cavity between the two side templates 10 and the top template 11. A pull ring 201 and a chute 103 are fixedly installed on the outer wall of the formwork box 1. The chute 103 is located below the pull ring 201 and is used to pass concrete into the mold cavity formed between the two side templates 10 and the top template 11. The pull ring 201... Ropes 2 are threaded through the outer wall of the formwork box 1. The ropes 2 are used to pull the formwork box 1 to move on the surface of the dam body. A scraping component is installed inside the formwork box 1. The scraping component is located on one side of the two side templates 10. The scraping component is used to scrape the surface of the formed concrete block when the top template 11 and the two side templates 10 are separated from the formed concrete block. A spraying component is installed inside the formwork box 1. The spraying component is located on one side of the scraping component. The spraying component includes multiple nozzles 9. The spraying component is used to spray curing agent onto the formed concrete block through the multiple nozzles 9. Since the construction of dam face panels is mostly carried out on high slopes, after the slipform is removed, it is difficult for manual spraying of curing agent onto the slope concrete quickly and evenly. This may result in the slope concrete not being covered properly or having local gaps in curing due to untimely curing, which in turn causes uneven strength growth of the concrete and affects its crack resistance and impermeability. When concrete pouring is required for the dam, this device is placed on the surface of the dam body. Then, rope 2 is passed through the pull ring 201, and one end of rope 2 is connected to a winch. When the device is on the dam surface, concrete grouting is performed from the chute 103 into the formwork box 1 via the grouting device. The concrete enters the mold cavity formed by the two side formworks 10 and the top formwork 11 through the chute 103. When the concrete completely fills the mold cavity, grouting is stopped. When the grout in the mold cavity has solidified, the winch is activated. The machine drives the rope 2 to rewind and move, and the rope 2 will pull the formwork box 1 to move through the pull ring 201. This causes the formwork box 1 to move the two side formworks 10 and the top formwork 11 inside it to a pouring position on the surface of the dam body, thereby realizing continuous pouring operation on the surface of the dam body. By pouring the dam body surface in this way, continuous pouring operation can be achieved. The formwork sliding and concrete pouring are carried out simultaneously, which greatly reduces the interval time between processes. It is especially suitable for the construction of large-span, large-area rockfill dam panels and significantly shortens the overall construction period. Meanwhile, slipform construction reduces the repeated disassembly and assembly of formwork materials, lowers construction costs, and solves the problems of traditional formwork construction, which requires segmented formwork erection, disassembly, and transportation, resulting in cumbersome procedures and long construction periods. When the formwork box 1 moves, the scraping component assists in scraping the surface of the formed concrete block through its movement, performing surface finishing work. At the same time, the spraying component sprays curing agent onto the formed concrete block through multiple nozzles 9 through its movement, thereby performing curing work. In this way, this device integrates the spraying function and the pouring function. The chemical spraying method allows for timely application of curing agents to the concrete blocks on the slope. Compared to manual climbing, this method saves manpower, improves the spraying effect, and facilitates concrete curing. It should be noted that the winch includes a drive source and a winding reel, primarily used to pull and wind up rope 2. The grouting device includes a vibrator and a grouting pipe, mainly used to inject concrete into the mold cavity for vibration and shaping. Both are existing technologies, so they are only described in this solution without showing their specific structures.
[0029] like Figures 5 to 6 As shown, a closed motor 1004 is symmetrically fixedly installed on the top of the horizontal plate 102. The output ends of the two closed motors 1004 are respectively fixedly connected to the top of the two side templates 10. The outer walls of the two side templates 10 are slidably connected to the inner wall of the mold box 1. Limiting rods 1003 are fixedly installed on the inner walls of the two side templates 10. Elastic blocks 1001 are slidably connected to the outer walls of the two limiting rods 1003. A pressure spring 1002 is provided between the top of the two elastic blocks 1001 and the inner walls of the two side templates 10. The two pressure springs 1002 are respectively placed outside the two limiting rods 1003. When this device is placed on the surface of the dam, the operation is performed by the closing motor 1004 at the top of the drive plate 102. The closing motor 1004 will drive the side template 10 to move downwards and fit against the surface of the dam. When the side template 10 moves downwards, it will also drive the elastic block 1001 downwards. When the elastic block 1001 contacts the surface of the dam, the closing motor 1004 will continue to drive the side template 10 to move. At this time, the elastic block 1001 will be restricted by the surface of the dam and will move by pressing the pressure spring 1002 against the limiting rod 1003 inside the side template 10. When the closing motor... When the machine 1004 pushes the side formwork 10 to contact the surface of the dam body, the operation of the closing motor 1004 is stopped. At this time, the elastic block 1001 will always fit between the dam body surface and the side formwork 10 through elastic deformation inside the side formwork 10, thereby sealing and blocking the side formwork 10 and the surface of the dam body. This prevents concrete from flowing out from the gap between the two due to the different heights of the dam body surface during pouring, and plays a role in tightly fitting the surface of the dam body. This can avoid the problem of too many construction joints caused by segmented pouring, reduce leakage channels, and make the concrete panel after pouring stronger in integrity and better in terms of impermeability and crack resistance.
[0030] like Figures 5 to 6 As shown, a hydraulic cylinder 12 is fixedly installed on the top of the horizontal plate 102. The output end of the hydraulic cylinder 12 passes through the inner wall of the horizontal plate 102 and is fixedly connected to the top of the top template 11. The outer wall of the top template 11 can be slidably connected to the inner side of the two side templates 10. When the closed motor 1004 drives the side formwork 10 to contact the dam surface, the hydraulic cylinder 12 is driven to work. The hydraulic cylinder 12 will drive the top formwork 11 to move between the two side formworks 10, thereby adjusting the position of the top formwork 11 up and down, and thus adjusting the thickness of the concrete to be poured on the dam surface. This helps to adjust the thickness of the concrete poured on the dam surface and increases the adaptability during use.
[0031] like Figures 7 to 8 As shown, the scraping assembly includes a support plate 7. The outer wall of the support plate 7 can be slidably connected to one side of the two side templates 10 and the top template 11 respectively. A hydraulic rod 8 is fixedly installed on the top of the mold box 1. The output end of the hydraulic rod 8 passes through the inner wall of the mold box 1 and is fixedly connected to the top of the support plate 7. The bottom end of the support plate 7 can be flush with the bottom of the top template 11. The bottom end of the support plate 7 can contact the surface of the dam body. The bottom end of the support plate 7 is made of elastic silicone. When the top formwork 11 and side formwork 10 are completed, the hydraulic rod 8 drives the positioning plate 7 to move downwards. The bottom end of the positioning plate 7 then comes into contact with the dam surface, forming a complete casting cavity. Concrete can then be poured into the cavity. When the concrete has set and it is necessary to move the top formwork 11 and side formwork 10, the hydraulic rod 8 drives the positioning plate 7 to move upwards, so that the bottom end of the positioning plate 7 is flush with the top formwork 11. When the formwork box 1 is moved on the dam surface by the rope 2, The bottom of the support plate 7 will scrape and smooth the surface of the concrete by moving, so as to avoid the surface of the concrete being uneven due to the scraping of the concrete surface when the top formwork 11 moves with the concrete. On the one hand, it can smooth the top of the concrete. On the other hand, during the first pour, the support plate 7 can assist the two side formworks 10 and the top formwork 11 to work, forming a blocking mold on one side of the two. This makes it easier to pour the concrete in the mold cavity for the first time. There is no need to set a limit plate on one side of the two during the first pour, which can save time and manpower.
[0032] like Figures 4 to 10 As shown, the spraying assembly also includes a horizontal spray box 6 and two side spray boxes 601. The horizontal spray box 6 and the two side spray boxes 601 are all located inside the mold box 1. The two side spray boxes 601 are fixedly installed on one side inside the mold box 1, and the horizontal spray box 6 is placed between the two side spray boxes 601. Multiple nozzles 9 are fixedly installed at the bottom of the horizontal spray box 6 and on one side of the two side spray boxes 601. The two side spray boxes 601 can be placed on both sides of the concrete block, and the horizontal spray box 6 can be placed directly above the concrete. When the formwork box 1 moves on the dam body by being pulled by the rope 2, the formwork box 1 will drive the transverse spray box 6 and the lateral spray box 601 to move together. When the transverse spray box 6 and the lateral spray box 601 are moving, they will spray curing agent on the top and sides of the formed concrete through the nozzle 9. With the continuous movement of the formwork box 1, a continuous moving and circling spray is formed on the formed concrete, which plays the role of circling spraying the formed concrete.
[0033] like Figures 7 to 8 As shown, a rack 703 is fixedly installed on one side of the horizontal spray box 6, a rack 701 is fixedly installed inside the abutment plate 7, a shaft is fixedly connected to the top of the horizontal plate 102, a gear 702 is rotatably connected to the outer wall of the shaft, the inner wall of the abutment plate 7 can slide and connect with the outer wall of the shaft, the teeth on the rack 701 and the rack 703 can mesh with the teeth on the gear 702, and one side of the horizontal spray box 6 is slidably connected with the outer wall of the abutment plate 7. When the hydraulic rod 8 moves the abutment plate 7 upward to reset, the abutment plate 7 will move the rack 701 upward. The rack 701 will then drive the gear 702 to rotate through tooth meshing. The gear 702 will then drive the rack 703 to move downward, thereby causing the rack 703 to move the transverse spray box 6 downward from above the abutment plate 7 on one side. When the bottom end of the abutment plate 7 moves to be flush with the bottom of the top formwork 11, the transverse spray box 6 will be positioned above the concrete, thus moving the transverse spray box 6 closer to the top of the concrete for easy spraying. The purpose of this setting is to spray the top of the concrete close to the transverse spray box 6, avoiding the inability to spray the top of the concrete evenly due to the transverse spray box 6 being set too high. It should be noted that in the initial state, the transverse spray box 6 is placed directly above the inside of the formwork box 1 to avoid damage to the dam surface protrusions in the initial state.
[0034] like Figures 3 to 9 As shown, a feeding device 5 is fixedly installed on the top of the horizontal plate 102, and a liquid flow pipe 501 is fixedly installed on the outer wall of the feeding device 5. The liquid flow pipe 501 is a rubber hose, and one end of the liquid flow pipe 501 is fixedly connected to the inner wall of the horizontal spray box 6. The outer wall of the liquid flow pipe 501 can be slidably connected to the inner wall of the horizontal plate 102. When the transverse spray box 6 sprays concrete through the nozzle 9, the feeding device 5 operates by driving the feeding device 5. The feeding device 5 then introduces the curing agent into the transverse spray box 6 through the liquid flow pipe 501, so that the transverse spray box 6 sprays the curing agent onto the surface of the concrete through the nozzle 9. This serves to replenish the curing agent in the transverse spray box 6. It should be noted that the transverse spray box 6 initially contains curing agent. The feeding device 5 includes a high-pressure liquid pump and a liquid storage tank. It is mainly used to introduce the curing agent in the liquid storage tank into the transverse spray box 6 through the high-pressure liquid pump. This is existing technology, so it is only described in this solution and the specific structure is not shown.
[0035] like Figures 9 to 10 As shown, multiple nozzles 9 are symmetrically and slidably equipped with blocking blocks 605 inside. The outer walls of the multiple blocking blocks 605 can be slidably connected to the inner walls of the two side spray boxes 601 and the transverse spray box 6, respectively. A return spring 606 is provided between the outer walls of the multiple blocking blocks 605 and the inner walls of the two side spray boxes 601 and the transverse spray box 6. An inclined pressure port is opened on one side of each of the multiple blocking blocks 605. When the feeding device 5 delivers the curing agent into the transverse spray box 6 through the liquid flow pipe 501, the curing agent will generate a certain pressure in the transverse spray box 6 due to the high pressure delivery of the feeding device 5. The curing agent will then squeeze the block 605 in the nozzle 9. The block 605 will then open the return spring 606 in the nozzle 9 due to the pressure of the curing agent. The curing agent placed in the transverse spray box 6 will then enter the nozzle 9 through the two blocks 605 and finally be sprayed onto the surface of the concrete through the nozzle 9. When the nozzle 9 finishes spraying the concrete, by stopping the feeding device 5 to deliver the internal material, the block 605 will lose its squeezing force. The return spring 606 will then push the two blocks 605 to close in the nozzle 9 through elasticity, thereby blocking the nozzle 9 and preventing the curing agent from flowing out. This plays the role of controlling the spraying and closing of the curing agent.
[0036] like Figures 5 to 9 As shown, two cavity tubes 602 are symmetrically fixedly installed on one side of the transverse spray box 6. One end of each cavity tube 602 is placed inside the two side spray boxes 601, and the outer walls of the two cavity tubes 602 can be slidably connected to the inner walls of the two side spray boxes 601. A flow limiting plate 604 is fixedly installed on the outer walls of both cavity tubes 602. The inner sides of the two flow limiting plates 604 are slidably connected to the outer walls of the two side spray boxes 601. A baffle 603 is fixedly installed on one end of each cavity tube 602. The outer walls of the two baffles 603 are slidably connected to the inner walls of the two side spray boxes 601. When the transverse spray box 6 moves, it moves the cavity tube 602 along with it. The cavity tube 602 then moves the flow restrictor 604 to conform to the outer wall of the side spray box 601. Simultaneously, the cavity tube 602 moves the baffle 603 within the side spray box 601. When the transverse spray box 6 stops moving, and the feeding device 5 delivers curing agent to the transverse spray box 6 through the liquid flow pipe 501, the transverse spray box 6 delivers curing agent to both side spray boxes 601 through the cavity tube 602. Combined with the restriction of the baffle 603 within the side spray box 601, the curing agent squeezes and pushes the block 605 to open, thereby... The curing agent is sprayed from the nozzles 9 on one side of the two side spray boxes 601, forming a complete ring spray with the transverse spray box 6 to spray the outside of the concrete, thus spraying the side of the concrete. Due to the different heights of the formed concrete, the baffle 603 can limit the flow rate in the side spray box 601 to prevent the curing agent from being sprayed out from the other nozzles 9 on one side of the side spray box 601, thus avoiding waste of the curing agent and limiting the spray range of the curing agent. It should be noted that in the initial state, the two side spray boxes 601 are the same as the transverse spray box 6, and the curing agent is introduced into both of them.
[0037] like Figures 1 to 2As shown, a counterweight 101 is installed inside the mold box 1. The counterweight 101 is used to tilt the mold box 1 for counterweight. A mounting frame 3 is fixedly installed on the top of the mold box 1. The mounting frame 3 is located directly above the pull ring 201 and the guide rail 4. A lighting lamp is installed inside the mounting frame 3. The surface of the dam body is symmetrically fixedly provided with guide rails 4. Two guide rails 4 are respectively placed on one side of the mold box 1. Rollers 401 are symmetrically fixedly installed on both sides of the guide rails 4. The two rollers 401 are slidably connected to the inside of the two guide rails 4. The mold box 1 moves on the surface of the dam body through the rollers 401. When installing this device onto the dam surface, a counterweight 101 of appropriate weight is placed inside the formwork box 1. Two guide rails 4 are then symmetrically placed on the dam surface, and rollers 401 are placed within each guide rail 4. When the winch pulls the formwork box 1 across the dam surface via the rope 2, the formwork box 1 can slide within the guide rails 4 via the rollers 401, providing auxiliary sliding and making the formwork box 1 more stable when sliding on the dam surface. Furthermore, as the formwork box 1 moves across the dam surface, the lighting inside the mounting frame 3 provides illumination. Illumination is applied between rope 2 and pull ring 201 and between chute 103 and formwork box 1 to facilitate inspection during operations and to facilitate pouring work on the dam surface at night. Rockfill dams have steep slopes and narrow working surfaces, making traditional formwork difficult and unsafe. This device, with its matching traction and anchoring system, can be stably attached to the dam slope, adapting to steep slope construction environments, reducing the risk of working at heights, and ensuring the safety of construction personnel. It should be noted that the weight of the counterweight 101 needs to be set according to the actual inclination of the dam surface.
[0038] Working principle: When concrete pouring is required for the dam, this device is placed on the surface of the dam body. Then, rope 2 is passed through the pull ring 201, and one end of rope 2 is connected to a winch. When the device is placed on the dam surface, concrete grouting is performed from the chute 103 into the mold box 1 via the grouting device. The concrete enters the mold cavity formed by the two side molds 10 and the top mold 11 through the chute 103. When the concrete completely fills the mold cavity, grouting is stopped. When the grout in the mold cavity forms, it is driven... The winch drives the rope 2 to move and rewind. The rope 2 then pulls the formwork box 1 through the pull ring 201, thereby moving the two side formworks 10 and the top formwork 11 inside the formwork box 1 to a pouring position on the surface of the dam body. This enables continuous pouring operations on the dam body surface. By performing pouring operations on the dam body surface in this way, continuous pouring operations can be achieved. The formwork sliding and concrete pouring are carried out simultaneously, which greatly reduces the interval time between processes. It is especially suitable for the construction of large-span, large-area rockfill dam panels and significantly shortens the overall construction period. Meanwhile, slipform construction can reduce the repeated disassembly and assembly of formwork materials, reduce construction costs, and solve the problems of traditional formwork construction, which requires segmented formwork erection, disassembly and transportation, which is complicated and has a long construction period. When the formwork box 1 is moving, the scraping component will assist in scraping the surface of the formed concrete block through its movement, and perform surface finishing work. At the same time, the spraying component will spray curing agent on the formed concrete block through multiple nozzles 9 through its movement, thereby performing curing work. In this way, the device can integrate the spraying function and the pouring function, and can spray curing agent on the slope concrete block in a timely manner. Compared with manually climbing to spray curing agent on the slope concrete, it saves manpower, improves the spraying effect on the slope concrete, and is more conducive to the curing work of concrete. When this device is placed on the surface of the dam, the operation is performed by the closing motor 1004 at the top of the drive plate 102. The closing motor 1004 will drive the side template 10 to move downwards and fit against the surface of the dam. When the side template 10 moves downwards, it will also drive the elastic block 1001 downwards. When the elastic block 1001 contacts the surface of the dam, the closing motor 1004 will continue to drive the side template 10 to move. At this time, the elastic block 1001 will be restricted by the surface of the dam and will move by pressing the pressure spring 1002 against the limiting rod 1003 inside the side template 10. When the closing motor... When the machine 1004 pushes the side formwork 10 to contact the surface of the dam body, the closing motor 1004 stops operating. At this time, the elastic block 1001 will always fit between the dam body surface and the side formwork 10 through elastic deformation inside the side formwork 10, thereby sealing and blocking the side formwork 10 and the surface of the dam body. This prevents concrete from flowing out from the gap between the two due to the different heights of the dam body surface during pouring, and plays a role in tightly fitting the surface of the dam body. This can avoid the problem of too many construction joints caused by segmented pouring, reduce leakage channels, and make the concrete panel after pouring stronger in integrity and better in terms of impermeability and crack resistance. When the closed motor 1004 drives the side formwork 10 to contact the dam surface, the hydraulic cylinder 12 is driven to work. The hydraulic cylinder 12 will drive the top formwork 11 to move between the two side formworks 10. The position of the top formwork 11 is adjusted up and down by its movement, thereby adjusting the thickness of the concrete to be poured on the dam surface. This plays a role in adjusting the thickness of the concrete poured on the dam surface and increasing the adaptability during use. When the top formwork 11 and side formwork 10 are completed, the hydraulic rod 8 drives the positioning plate 7 to move downwards. The bottom end of the positioning plate 7 then comes into contact with the dam surface, forming a complete casting cavity. Concrete can then be poured into the cavity. When the concrete has set and it is necessary to move the top formwork 11 and side formwork 10, the hydraulic rod 8 drives the positioning plate 7 to move upwards, so that the bottom end of the positioning plate 7 is flush with the top formwork 11. When the formwork box 1 is moved on the dam surface by the rope 2, The bottom of the support plate 7 will scrape and smooth the surface of the concrete by moving, so as to avoid the surface of the concrete being uneven due to the scraping of the concrete surface when the top formwork 11 moves with the concrete. On the one hand, it can smooth the top of the concrete. On the other hand, during the first pour, the support plate 7 can assist the two side formworks 10 and the top formwork 11 to work, forming a blocking mold on one side of the two, which can facilitate the first pour of concrete in the mold cavity. There is no need to set a limit plate on one side of the two during the first pour, which can save time and manpower. When the formwork box 1 moves on the dam body by being pulled by the rope 2, the formwork box 1 will drive the transverse spray box 6 and the lateral spray box 601 to move together. When the transverse spray box 6 and the lateral spray box 601 are moving, they will spray curing agent on the top and sides of the formed concrete through the nozzle 9. With the continuous movement of the formwork box 1, a continuous moving and surrounding spray is formed on the formed concrete, which plays the role of surrounding spraying the formed concrete. When the hydraulic rod 8 moves the abutment plate 7 upward to reset, the abutment plate 7 will move the rack 701 upward. The rack 701 will then drive the gear 702 to rotate through tooth meshing. The gear 702 will then drive the rack 703 to move downward, thereby causing the rack 703 to move the transverse spray box 6 downward from above the abutment plate 7 on one side. When the bottom of the abutment plate 7 moves to be flush with the bottom of the top formwork 11, the transverse spray box 6 will be positioned above the concrete, thus moving the transverse spray box 6 closer to the top of the concrete to facilitate spraying the top of the concrete. The purpose of this setting is to use the transverse spray box 6 to spray the top of the concrete closer to it, which can avoid the inability to spray the top of the concrete evenly due to the transverse spray box 6 being set too high. When the horizontal spray box 6 sprays concrete through the nozzle 9, the feeding device 5 is driven to operate. The feeding device 5 will then pass the curing agent into the horizontal spray box 6 through the liquid flow pipe 501, so that the horizontal spray box 6 sprays the curing agent onto the surface of the concrete through the nozzle 9, which plays the role of replenishing the curing agent in the horizontal spray box 6. When the feeding device 5 delivers the curing agent into the transverse spray box 6 through the liquid flow pipe 501, the curing agent will generate a certain pressure in the transverse spray box 6 due to the high pressure delivery of the feeding device 5. The curing agent will then squeeze the block 605 in the nozzle 9. The block 605 will then squeeze the return spring 606 in the nozzle 9 to open due to the pressure of the curing agent. The curing agent placed in the transverse spray box 6 will then enter the nozzle 9 through the two block 605 and finally be sprayed onto the surface of the concrete through the nozzle 9. When the nozzle 9 finishes spraying the concrete, by stopping the feeding device 5 to deliver the internal material, the block 605 will lose its squeezing force. The return spring 606 will then push the two block 605 in the nozzle 9 to close through elasticity, thereby blocking the nozzle 9 and preventing the curing agent from flowing out. This plays the role of controlling the spraying and closing of the curing agent. When the transverse spray box 6 moves, it moves the cavity tube 602 along with it. The cavity tube 602 then moves the flow restrictor 604 to conform to the outer wall of the side spray box 601. Simultaneously, the cavity tube 602 moves the baffle 603 within the side spray box 601. When the transverse spray box 6 stops moving, and the feeding device 5 delivers curing agent to the transverse spray box 6 through the liquid flow pipe 501, the transverse spray box 6 delivers curing agent to both side spray boxes 601 simultaneously through the cavity tube 602, in conjunction with the baffle 603's constriction within the side spray box 601. The curing agent will squeeze and push the block 605 to open, so that it will be sprayed out from the nozzles 9 on one side of the two side spray boxes 601, forming a complete ring spray with the transverse spray box 6 to spray the outside of the concrete, which can spray the side of the concrete. Since the height of the formed concrete is different, the baffle 603 can limit the flow in the side spray box 601 to prevent the curing agent from being sprayed out from the other nozzles 9 on the side of the side spray box 601, which would cause waste of the curing agent and limit the spraying range of the curing agent. When installing this device onto the dam surface, a counterweight 101 of appropriate weight is placed inside the formwork box 1. Then, two guide rails 4 are symmetrically placed on the dam surface, and rollers 401 are placed in the two guide rails 4 respectively. When the winch pulls the formwork box 1 on the dam surface via the rope 2, the formwork box 1 can slide on the guide rails 4 via the rollers 401 to assist in sliding operations, making the formwork box 1 more stable when sliding on the dam surface. When the formwork box 1 moves on the dam surface, the lighting in the mounting frame 3 can illuminate the area between the rope 2 and the pull ring 201 and between the chute 103 and the formwork box 1, making it easier to check the operation between the two and facilitating the pouring operation on the dam surface at night.
