[0033] As shown in the specific implementation, Figure 5 and Figure 6 at least one caulking opening 25 is arranged between backflow groove 24 and the front side outer wall of inner smoothing plate 14, through caulking opening 25 and caulking groove 23, the recessed part can be filled multiple times, so that the filling is sufficient, similarly, when the concrete passes through the recessed wall surface, it can be filled through the distillation of caulking opening 25, when there is no recess, the concrete can flow into collecting groove 21 through backflow groove 24, and then can be circulated.

[0034] In a specific implementation, a plurality of air flap strips 26 are installed on the inner wall of the backflow groove 24, and the air flap strips 26 are arranged below the filling groove 23 and the filling opening 25. The air flap strips 26 can prevent the concrete from flowing directly downward from the backflow groove 24. When passing through the recess, the concrete can be preferentially discharged through the filling groove 23 and the filling opening 25 under the action of the air flap strips 26 to complete the filling. When there is no recess, the air flap strips 26 can be pushed downward by the pressure above, so that enough space can be formed between the air flap strips 26 and the backflow groove 24 for the concrete to flow downward.

[0035] In a specific implementation, as shown in Figure 5 , Figure 7 and Figure 8 , an auxiliary discharging assembly 27 for preventing blockage in the collection opening 22 is arranged between the outer frame plate 13 and the inner troweling plate 14.

The driving motor 2703 can drive the connecting piece 2702 and the roller 2701 to rotate. When the roller 2701 rotates, the concrete at the collection opening 22 can be continuously pushed into the collection groove 21, thereby preventing blockage. A plurality of pushing pieces 28 are uniformly installed on the edges of the roller 2701. The pushing pieces 28 can further enhance the pushing effect.

[0036] In a specific implementation, as shown in Figure 1 , a variable frequency vibrator 9 is installed on the rear side of the outer frame plate 13. The variable frequency vibrator 9 can facilitate the vibration of the entire slip form 5 during troweling.

[0037] In a specific implementation, the driving arm structure 2 includes a fixed arm 10, an adjusting arm 4, a three-head connecting block 3, a first adjusting oil cylinder 12, and a mechanical joint 7. The fixed arm 10 is fixedly installed on the construction vehicle 1. The three-head connecting block 3 is rotatably connected to the fixed arm 10. The first adjusting oil cylinder 12 is rotatably installed on the fixed arm 10. One end of the three-head connecting block 3 is rotatably installed on the output end of the first adjusting oil cylinder 12. The adjusting arm 4 is fixedly connected to the three-head connecting block 3. The mechanical joint 7 is rotatably connected to the end of the adjusting arm 4 and the outer frame plate 13. The first adjusting oil cylinder 12 can control the three-head connecting block 3 to rotate with the fixed arm 10 as the center, so as to control the adjusting arm 4 and the slip form 5 to move up and down, thereby facilitating the control of the slip form 5 to move up and down on the wall surface.

[0038] In the specific implementation, the driving arm structure 2 further comprises a second adjusting oil cylinder 6, a hinged seat 8 and a telescopic rod set 11. The second adjusting oil cylinder 6 is rotatably installed at the end of the adjusting arm 4, and the telescopic end of the second adjusting oil cylinder 6 is rotatably connected to the upper rear side of the outer frame plate 13. The hinged seat 8 is rotatably connected to the lower side of the adjusting arm 4 and the lower rear side of the outer frame plate 13, respectively. The telescopic rod set 11 is rotatably installed at one end of the lower side of the adjusting arm 4 and at the other end of the hinged seat 8. The telescopic rod set 11 can be controlled to rotate by the telescopic extension of the second adjusting oil cylinder 6, so that the sliding formwork 5 can be always closely attached to the wall surface when moving up and down. When the first adjusting oil cylinder 12 is extended, the second adjusting oil cylinder 6 is retracted. At this time, the adjusting arm 4 and the sliding formwork 5 move downward. The upper half of the sliding formwork 5 is rotatably driven by the second adjusting oil cylinder 6 to rotate the hinged seat 8, and the telescopic rod set 11 is extended and the end thereof is adaptively rotated. When the first adjusting oil cylinder 12 is retracted, the second adjusting oil cylinder 6 is extended. At this time, the adjusting arm 4 and the sliding formwork 5 move upward. The upper half of the sliding formwork 5 is rotatably driven by the second adjusting oil cylinder 6 to rotate the hinged seat 8, and the telescopic rod set 11 is retracted and the end thereof is adaptively rotated. Therefore, the sliding formwork 5 can be always closely attached to the wall surface when moving up and down.

[0039] In this embodiment, the wall surface sprayed with concrete can be smoothed by the construction equipment. The excess concrete can be automatically recycled and the recessed part can be filled by the internal structure of the sliding formwork 5 during smoothing, so as to greatly improve the wall surface quality and ensure the effective use of materials, prevent waste, and smooth the wall surface sprayed with concrete by the sliding formwork 5 during processing. The sliding formwork 5 can be conveniently moved to the wall surface by the construction vehicle 1, and the sliding formwork 5 can be moved up and down on the wall surface by the driving arm structure 2 and can be ensured to be tightly attached to the wall surface. It should be noted that the sliding formwork 5 needs to be operated from the top of the wall surface to the bottom. When the sliding formwork 5 moves downward, the uppermost position of the collection slope 16 contacts and smooths the concrete on the wall surface. There is a certain space between the collection slope 16 and the concrete layer. During smoothing, the inner smoothing plate 14 can scrape the excess concrete to the position of the collection slope 16, and the concrete is extruded to the material blocking groove 18 as it moves downward. The concrete above the material blocking groove 18 can be recycled into the collection groove 21 through the collection port 22, so as to collect the excess concrete, reduce material waste, and reduce subsequent cleaning work. The concrete collected in the collection groove 21 can be pumped into the upper storage tank 19 by the sand pumping pump 15. It should be noted that the storage tank 19 needs to be filled with concrete in the initial stage. The concrete in the storage tank 19 can be discharged from the caulking groove 23 under the action of pressure under the transfer of the sand pumping pump 15. The concrete can fill the recessed wall surface when it passes through the recessed wall surface. When there is no recess, the air flap strip 26 can be pushed downward by the upper pressure, so that enough space can be formed between the air flap strip 26 and the backflow groove 24 for the concrete to flow downward. Then the concrete can be circulated. The caulking port 25 and the caulking groove 23 can be filled for multiple times, so as to ensure sufficient filling, and thus the work of automatically collecting excess concrete and automatically filling recesses can be completed.
