[0017] It should be noted that the illustrations provided in the following embodiments are only used to illustrate the basic concept of the present invention in a schematic manner, and thus the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0018] See also Figure 1-7As shown, the channel construction device for water conservancy engineering provided by the embodiment of the present invention includes a template assembly 10, a support frame 30 and a slurry guide device 20; two rows of the template assemblies 10 are respectively arranged on both sides of the cast-in-place channel bottom plate 100, and each row of the template assemblies 10 includes an inner template 12 and an outer template 11, and a cavity for casting the channel side wall is formed between the inner template 12 and the outer template 11; the support frame 30 is arranged between the inner templates 12 of the two rows of the template assemblies 10, and is used to support the inner template 12; the slurry guide device 20 is arranged above the support frame 30, and the slurry guide device 20 includes two mutually hinged slurry guide plates 21, the hinge shaft 23 between the two slurry guide plates 21 is supported on the support frame 30, and the ends of the two slurry guide plates 21 away from the hinge shaft 23 are respectively placed on the upper edges of the two rows of the inner templates 12, so that the two slurry guide plates 21 form a slope-like structure that gradually decreases from the center of the cast-in-place channel bottom plate 100 to both sides; the upper ends of the two slurry guide plates 21 are respectively provided with comb-tooth structures 211, and the comb-tooth structures 211 of the two slurry guide plates 21 cross each other to form a receiving trough 201 for receiving concrete slurry. It should be noted that in a specific embodiment, a corresponding support structure should also be provided on the outside of the outer template 11. Since the support structure of the outer template 11 is not the focus of the protection required by the present invention, it will not be described in detail.

[0019] The present invention forms a sloped structure that gradually descends from the center of the channel bottom plate to both sides through two mutually hinged slurry guide plates 21. This design uses the principle of gravity to allow the concrete slurry to flow naturally to the cavities on both sides, greatly reducing the need for manual intervention, thereby improving the pouring efficiency. The upper ends of the two slurry guide plates 21 are provided with mutually intersecting comb-shaped structures 211 to form a receiving trough 201. This design can not only effectively receive and guide the concrete slurry, but also play a certain role in dispersion and uniform distribution during the slurry flow process, effectively avoiding the problem of local accumulation or insufficient supply, thereby improving the uniformity of concrete pouring. In addition, the present invention hinges the two slurry guide plates 21, which can flexibly adjust the span of the slurry guide device 20 according to the width of the channel on the one hand, and on the other hand, it is also convenient to reduce the volume of the slurry guide device 20 during transportation, reduce transportation costs, and improve flexibility.

[0020] See also Figure 1-4As shown, in an optional embodiment of the present invention, the slurry guide device 20 is connected to the support frame 30 in a detachable manner, or the slurry guide device 20 is movably connected to the support frame 30 along the length direction of the cast-in-place channel bottom plate 100. The detachable connection mode allows the slurry guide device 20 to be easily assembled and disassembled. This design is not only convenient for rapid installation before construction, but also convenient for cleaning and maintenance after construction. When the construction device needs to be replaced or repaired, the construction personnel can quickly remove the slurry guide device 20 without interfering with the entire construction system, thereby improving the flexibility and efficiency of construction; the movable connection mode allows the slurry guide device 20 to move freely along the length direction of the cast-in-place channel bottom plate 100. This design enables the slurry guide device 20 to adapt to the construction requirements of channels of different lengths and shapes, and flexibly adjust its position and angle to ensure that the concrete slurry can be most evenly distributed to the cavities on both sides. In addition, the movable connection can also reduce the potential impact on the slurry guide device 20 caused by the deformation or movement of the template or the support frame 30 during the construction process, further ensuring the construction quality.

[0021] See also Figure 5-7 As shown, in an optional embodiment of the present invention, the two sides of the slurry guide plate 21 are provided with side plates 22, and the side plates 22 are hinged with the slurry guide plate 21 so that the side plates 22 can switch between the vertical and parallel states relative to the slurry guide plate 21; and a holding mechanism is also included, and the holding mechanism is equipped to keep the side plates 22 in a vertical state with the slurry guide plate 21 in a vertical state with the slurry guide plate 21. When the side plates 22 and the slurry guide plate 21 are in a vertical state, the side plates 22 can effectively close the two side edges of the slurry guide plate 21 to form a complete slurry guide channel to prevent the concrete slurry from overflowing during the pouring process; when transporting, storing or adjusting the structure of the construction device, the slurry guide plate 21 and the side plates 22 may need to be folded or unfolded. When the side plates 22 and the slurry guide plate 21 are in a parallel state, the side plates 22 can be flush with the slurry guide plate 21, further reducing the occupied space of the slurry guide device 20 after folding, facilitating the loading of the transport vehicle and the arrangement of the storage site, thereby reducing the transportation and storage costs of the construction device.

[0022] See also Figure 5As shown, in an optional embodiment of the present invention, the slurry guide plate 21 is connected to the side plate 22 by a limit hinge 27, and the limit hinge 27 is assembled to limit the relative position of the side plate 22 and the slurry guide plate 21 between the vertical and parallel states. During the pouring process, the side plate 22 needs to be kept in a vertical state to prevent the slurry from overflowing. The limit hinge 27 can firmly lock the side plate 22 in a vertical position to avoid accidental movement of the side plate 22 due to slurry impact or construction vibration, thereby ensuring the stability of the construction and the precise delivery of the slurry; when the slurry guide device 20 needs to be folded, the limit hinge 27 can quickly and accurately switch the side plate 22 to a parallel state, flush with the slurry guide plate 21, thereby reducing the size of the device. This fast switching function improves the adjustment efficiency of the construction device and facilitates transportation, storage and on-site deployment. Construction workers can switch the side panel 22 between the vertical and parallel states with simple movements without using additional tools or making complicated adjustments, thereby improving the convenience of operation and construction efficiency; the limit hinge 27 avoids the situation where the side panel 22 is in the middle position due to improper operation and affects the construction effect, further improving the reliability of construction.

[0023] See also Figure 5 , 7 As shown, in an optional embodiment of the present invention, the holding mechanism includes a swing arm 24, the swing arm 24 is rotatably arranged relative to the guide plate 21, and the rotation axis is parallel to the hinge shaft 23 between the two guide plates 21, the swing arm 24 is configured to be able to swing between at least a first position and a second position, when the swing arm 24 is in the first position, the swing arm 24 is in contact with the outer wall of the side plate 22 in the first state, the first state is a state when the side wall is perpendicular to the guide plate 21, and when the swing arm 24 is in the second position, the swing arm 24 is separated from the side plate 22. In a specific embodiment, the two side plates 22 on the same side of the two guide plates 21 share the same swing arm 24, and one of the two side plates 22 located on the outer side is provided with a slot 25 that cooperates with the swing arm 24. The swing arm 24 is used to limit the position of the side panel 22. On the one hand, it can effectively support the side panel 22 to keep it stably in a vertical state. On the other hand, the swing arm 24 can swing to a state parallel to the guide plate 21, further reducing the occupied space after folding.

[0024] See also Figure 5 , 7 As shown, in an optional embodiment of the present invention, the swing arm 24 is rotatably connected to the hinge shaft 23 between the two guide plates 21. Figure 7As shown, when the slurry guiding device 20 is in a folded state, the swing arm 24 is located between the two layers of slurry guiding plates 21 and does not occupy additional space, thereby minimizing the storage and transportation space requirements of the slurry guiding device 20 after being folded.

[0025] See also Figure 3 , 5 As shown, in an optional embodiment of the present invention, a buffer pad 26 is provided on the bottom surface of one end of the guide plate 21 away from the hinge shaft 23, which is matched with the upper edge of the inner template 12. The buffer pad 26 is a tubular structure made of elastic material with a semicircular cross-section. The elastic material properties of the buffer pad 26 enable it to effectively absorb the impact force generated when the guide plate 21 contacts the upper edge of the inner template 12. During the construction process, the guide plate 21 may collide with the inner template 12 due to the flow of concrete slurry or the movement of the construction device. The elastic effect of the buffer pad 26 can reduce the direct impact of such collision on the inner template 12 and the guide plate 21, thereby reducing the wear of both and extending the service life of the device. The semicircular cross-sectional design of the buffer pad 26 enables it to better cooperate with the upper edge of the inner template 12. The elastic effect of the buffer pad 26 enables the slurry guide plate 21 to be placed on the upper edge of the inner template 12 more stably, reducing the shaking of the slurry guide plate 21 caused by construction vibration or slurry flow, thereby improving the stability of the slurry guide device 20. The improved stability of the slurry guide plate 21 helps the concrete slurry to flow more evenly into the cavities on both sides, avoiding the problem of uneven slurry distribution caused by the shaking of the slurry guide plate 21, thereby improving the construction quality; the elastic material properties of the buffer pad 26 enable it to adapt to different construction conditions. During the construction process, the inner template 12 may undergo slight deformation due to the pressure of the concrete slurry or external environmental factors. The elastic effect of the buffer pad 26 can compensate for this deformation, ensuring that the slurry guide plate 21 is always in close contact with the inner template 12, thereby ensuring the smooth progress of the construction; the semicircular cross-sectional design of the buffer pad 26 enables it to adapt to the upper edge of the inner template 12 of different sizes and shapes, improving the versatility and adaptability of the slurry guide device 20.

[0026] See also Figure 2 , 3As shown, in an optional embodiment of the present invention, a support rod 40 is provided between the slurry guide device 20 and the support frame 30, and the support rod 40 includes a fixed portion 41 and a telescopic portion 42, the fixed portion 41 is fixedly connected to the support frame 30, and the telescopic portion 42 is movably connected to the fixed portion 41 in the vertical direction, and a locking mechanism 44 for maintaining the telescopic portion 42 at any height is provided between the fixed portion 41 and the telescopic portion 42, and an arc-shaped support plate 43 for accommodating the hinge shaft 23 is provided at the upper end of the telescopic portion 42. In a specific embodiment, an expansion tube can be provided on the fixed portion 41, and the telescopic portion 42 can be inserted into the expansion tube. The locking mechanism 44 can be, for example, a screw sleeve threadedly connected to the expansion tube, and the fixing and release of the telescopic portion 42 are achieved by tightening the screw sleeve. It should be understood that the channel width and height of different construction projects may be different. The present invention can adjust the span of the slurry guiding device 20 by hinged connection between the two slurry guiding plates 21. At the same time, the support rod 40 provided by the present invention can adapt to different heights of the slurry guiding device 20, thereby improving the versatility of the slurry guiding device 20.

[0027] See also Figure 1 , 3 As shown in Figure 4, in an optional embodiment of the present invention, the support frame 30 includes columns 31, cross braces 32, cross beams 34 and longitudinal beams 33. The two rows of columns 31 are respectively fitted with the inner walls of the two rows of inner templates 12. A plurality of cross braces 32 are supported between the two rows of columns 31 in the horizontal direction. Both ends of the cross braces 32 are respectively provided with retractable top rods 321. Each adjacent cross brace 32 is connected to each other through the cross beam 34 and the longitudinal beam 33. The fixed portion 41 of the support rod 40 is fixedly connected to the cross brace 32 in a detachable manner. In a specific embodiment, the column 31 can be, for example, a channel steel, the cross brace 32, the cross beam 34 and the longitudinal beam 33 can be, for example, a disc-type scaffolding, and the top rods 321 at both ends of the cross brace 32 can adopt the same design as the retractable portion 42 of the support rod 40.

[0028] In summary, the present invention forms a slope-like structure that gradually decreases from the center of the channel bottom plate to both sides through two mutually hinged slurry guide plates 21. This design uses the principle of gravity to allow the concrete slurry to flow naturally to the cavities on both sides, greatly reducing the need for manual intervention, thereby improving the pouring efficiency. The upper ends of the two slurry guide plates 21 are provided with mutually intersecting comb-like structures 211 to form a material receiving trough 201. This design can not only effectively receive and guide the concrete slurry, but also play a certain role in dispersion and uniform distribution during the slurry flow process, effectively avoiding the problem of local accumulation or insufficient supply, thereby improving the uniformity of concrete pouring. In addition, the present invention hinges the two slurry guide plates 21, which can flexibly adjust the span of the slurry guide device 20 according to the width of the channel on the one hand, and on the other hand, it is also convenient to reduce the volume of the slurry guide device 20 during transportation, reduce transportation costs, and improve flexibility. The detachable connection mode enables the slurry guide device 20 to be easily assembled and disassembled. This design is not only convenient for quick installation before construction, but also convenient for cleaning and maintenance after construction. When the construction device needs to be replaced or repaired, the construction personnel can quickly remove the slurry guide device 20 without interfering with the entire construction system, thereby improving the flexibility and efficiency of the construction; the movable connection mode allows the slurry guide device 20 to move freely along the length direction of the cast-in-place channel bottom plate 100. This design enables the slurry guide device 20 to adapt to the construction requirements of channels of different lengths and shapes, and flexibly adjust its position and angle to ensure that the concrete slurry can be most evenly distributed to the cavities on both sides. In addition, the movable connection can also reduce the potential impact on the slurry guide device 20 caused by deformation or movement of the formwork or support frame 30 during construction, further ensuring the construction quality. When the side panels 22 and the slurry guide plate 21 are in a vertical state, the side panels 22 can effectively close the two side edges of the slurry guide plate 21 to form a complete slurry guide channel to prevent the concrete slurry from overflowing during the pouring process; during transportation, storage or when the construction device structure needs to be adjusted, the slurry guide plate 21 and the side panels 22 may need to be folded or unfolded. When the side panels 22 and the slurry guide plate 21 are in a parallel state, the side panels 22 can be flush with the slurry guide plate 21, further reducing the space occupied by the slurry guide device 20 after folding, facilitating the loading of transportation vehicles and the layout of storage sites, thereby reducing the transportation and storage costs of the construction equipment.
