[0002] An aqueduct is an elevated water channel that transports water across rivers, canals, valleys, depressions, and roads. It is commonly used for irrigation, flood control, and sediment removal. Large aqueducts can also be navigable. Aqueducts are mainly constructed using materials such as masonry, concrete, and reinforced concrete. Aqueduct projects often employ precast aqueducts for installation. In the production of precast aqueducts, a formwork is first erected, then concrete is poured into the formwork to fill it completely. Once the concrete has fully hardened, the formwork frame is removed, allowing the precast aqueduct to be demolded, forming the precast aqueduct body.

[0003] An existing precast aqueduct body formwork structure that facilitates grouting includes an outer formwork, an inner formwork, and two end formworks. The outer and inner formworks form a casting cavity, and the precast aqueduct is made by injecting concrete into the casting cavity. However, the two end formworks are fixed to the outer and inner formworks with bolts. When demolding the precast aqueduct, multiple bolts need to be removed, which is cumbersome and time-consuming, greatly affecting the demolding efficiency. Utility Model Content

[0038] Please refer to Figures 1-8 The embodiment of the utility model provides an equipment convenient for prefabricated aqueduct demoulding, including formwork assembly 1, fixed assembly 2 and base 3, wherein, formwork assembly 1 includes outer formwork 11, inner formwork 12 and two end formworks 13, inner formwork 11 is located directly above outer formwork 11, two end formworks 13 are arranged at the two ends of outer formwork 11 and inner formwork 12 respectively, and two end formworks 13 are embedded between outer formwork 11 and inner formwork 12, and form pouring cavity with outer formwork 11 and inner formwork 12. Specifically, outer formwork 11 is fixed on the top surface of base 3 through support, outer formwork 11 and inner formwork 12 are both in circular arc shape, the diameter of outer formwork 11 is greater than the diameter of inner formwork 12 and is arranged with the same center, the upper and lower ends of end formwork 13 are both provided with the same arc as the arc of outer formwork 11, when end formwork 13 is embedded between outer formwork 11 and inner formwork 12, pouring cavity is formed by surrounding four thereof, after surrounding, the top of outer formwork 11, inner formwork 12 and end formwork 13 form longitudinal gap communicating with pouring cavity, concrete is injected into pouring cavity through gap, and prefabricated aqueduct is formed after concrete solidification, and the shape of prefabricated aqueduct is consistent with the shape of pouring cavity;

[0039] Preferably, the fixing components 2 are symmetrically arranged in two sets about the length of the outer template 11 and the inner template 12, including a driving component 21 and a fixing component 22. The driving component 21 is connected to the fixing component 22, and the driving component 21 is used to drive the fixing component 22 to move closer to or away from the end template 13, so that the fixing component 22 fixes or releases the connection between the end template 13 and the outer template 11 and the inner template 12. Specifically, the driving component 21 is disposed on the base 3.

[0040] In this embodiment, when assembling the template assembly 1, the end template 13 is first fitted with the outer template 11 and the inner template 12. Then, the driving component 21 drives the fixing component 22 to approach the end template 13. The fixing component 22 fixes the connection between the end template 13 and the outer template 11 and the inner template 12. Subsequently, concrete is injected into the pouring cavity through the grouting equipment. After the concrete solidifies, the demolding operation is performed. During demolding, the driving component 21 drives the fixing component 22 away from the end template 13, so that the fixing component 22 is detached from the connection between the end template 13 and the outer template 11 and the inner template 12, releasing the fixation at the connection. Then, the inner template 12 and the two end templates 13 can be removed to easily take out the precast aqueduct, completing the demolding of the precast aqueduct. Compared with using bolts for fixing, the use of fixing components in this application is more convenient, and the disassembly process does not require disassembling multiple bolts. The connection can be released by operating the driving component 21, making demolding simpler and faster, and improving the demolding efficiency of the precast aqueduct.

[0041] In a preferred embodiment, such as Figure 6 and Figure 7 As shown, positioning grooves are provided at both ends of the top surface of the outer template 12 and at both ends of the bottom surface of the inner template, and positioning strips 131 matching the positioning grooves are provided at both the upper and lower ends of the two end templates 13.

[0042] In this embodiment, the positioning groove is set as an arc-shaped groove, and the positioning strip 131 is also set as an arc-shaped plate structure. When assembling the template assembly 1, the positioning strips 131 at the bottom of the two end templates 13 are first inserted into the positioning grooves on the outer template 11 for fixation, and then the inner template 12 is pressed on the top of the end template 13, and the positioning strips 131 at the top of the end template 13 are embedded in the positioning grooves on the inner template 12 for fixation. The setting of the positioning strips 131 and the positioning grooves facilitates the quick and accurate determination of the installation and fixing positions between the end template 13, the outer template 11, and the inner template 12.

[0043] In a preferred embodiment, such as Figure 3 and Figure 7 As shown, the positioning strip 131 is provided with multiple first fixing holes, and the outer template 11 and the inner template 12 are each provided with multiple second fixing holes 111 and third fixing holes, and the second fixing holes 111 and the third fixing holes correspond one-to-one with the first fixing holes.

[0044] Preferred, such as Figure 4 , Figure 6 and Figure 7 As shown, the fixing member 22 includes a fixing plate 221. The fixing plate 221 is provided with a plurality of fixing posts 222 corresponding one-to-one with the second fixing holes 111 on the side near the end template 13. The driving member 21 is connected to the fixing plate 221. When the driving member 21 drives the fixing plate 221 closer to the end template 13, the fixing posts 222 pass through the second fixing hole 111 and the first fixing hole and are inserted into the third fixing hole for fixation. When the driving member 21 drives the fixing plate 22 away from the end template 13, the fixing posts 222 are pulled out from the first fixing hole and the third fixing hole, releasing the fixation of the template assembly 1.

[0045] In this embodiment, when the driving component 21 drives the fixing plate 221 closer to the end template 13, the fixing post 222 sequentially passes through the second fixing hole 111, the first fixing hole, and then inserts into the third fixing hole, thereby fixing the end template 13 to the outer template 11 and the inner template 12, allowing for rapid assembly of the template assembly 1. After the precast aqueduct is formed, the driving component 21 again drives the fixing plate 221 away from the end template 13, causing the fixing post 222 to disengage from the first fixing hole, the second fixing hole 111, and the third fixing hole, releasing the fixing at the connection between the end template 13 and the outer template 11 and the inner template 12. Then, the inner template 12 and the end template 13 can be removed, making it easy to remove the precast aqueduct. Compared to using bolts for fixing, this application is faster and more convenient in terms of demolding time.

[0046] In a preferred embodiment, such as Figure 4 and Figure 6 As shown, a baffle plate 223 is provided on the side of the fixing plate 221 near the end template 13. Specifically, the baffle plate 223 is located in the middle of the fixing plate 221. When the fixing post 222 is inserted into the third fixing hole for fixing, the baffle plate 223 abuts against the surface of the end template 13. The baffle plate 223 can apply force to the end template 13, so that the fixing post 222 is firmly stuck in the third fixing hole.

[0047] In a preferred embodiment, such as Figure 1 and Figure 5 As shown, the drive component 21 includes two sets of threaded rods 211 rotatably mounted on the base 3, a connecting plate 212 threadedly connected to the threaded rods 211, and a synchronous pulley 213 fixedly sleeved on the outside of the threaded rods 211. The fixing plate 221 is fixedly connected to the connecting plate 212. The two sets of threaded rods 211 are arranged in parallel, and one end of one set of threaded rods 211 is provided with a rotating handle 214. The two sets of synchronous pulleys 213 are connected by a synchronous belt 215.

[0048] In this embodiment, rotating the handle 214 can drive the threaded rod 211 to rotate, thereby causing the fixing plate 221 to translate along the axial direction of the threaded rod 211. The two sets of threaded rods 211 serve as limiters, so that when the threaded rods 211 rotate, they can drive the connecting plate 212 connected to them to translate along its axial direction. The surfaces of both sets of threaded rods 211 are provided with threads, which can improve the stability of the fixing plate 221 when it is fixed, thereby improving the firmness of the fixing post 222 inserted into the third fixing hole.

[0049] In a preferred embodiment, such as Figure 7 and Figure 8 As shown, the fixing component 2 also includes a locking component 23, which includes a locking sleeve 231, a locking rod 232 threadedly fitted inside the locking sleeve 231, and a fixing sleeve 233 fixedly connected to the locking rod 232. The fixing sleeve 233 is slidably connected to the threaded rod 211. The cross-section of the locking sleeve 231 is annular. When the fixing post 222 is inserted into the first fixing hole for fixing, the locking sleeve 231 moves downward and inserts into the locking hole 31 opened on the base 3 for fixing.

[0050] In this embodiment, the locking hole 31 on the base 3 is a circular hole, and the diameter of the circular hole is slightly larger than the diameter of the locking sleeve 231.

[0051] Each set of threaded rods 211 is equipped with a locking element 23. The locking element 23 is located on the side of the fixing plate 221 away from the end template 13. The fixing sleeve 233 is annular, and the diameter of the through hole in the center of the fixing sleeve 233 is larger than the diameter of the threaded rod 211. When the fixing post 222 on the fixing plate 221 is inserted into the third fixing hole for fixation, the locking element 23 can be manually moved so that the side of the fixing sleeve 233 abuts against the connecting plate 212. Then, the locking sleeve 231 is rotated and moves downward until the locking sleeve 231 is inserted into the locking hole 31 for fixation. The locking element 23 can further fix the position of the fixing plate 221, prevent the fixing plate 221 from slipping off the threaded rod 211, improve the firmness of the fixing post 222 inserted into the third fixing hole, and thus improve the connection stability of the end template 13, the outer template 11, and the inner template 12.

[0052] Working principle:

[0053] When assembling the template assembly 1, the end template 13 is first fitted with the outer template 11 and the inner template 12. Then, the fixing plate 221 is driven close to the end template 13 by the driving component 21, so that the fixing column 222 passes through the second fixing hole 111 and the first fixing hole in sequence and is inserted into the third fixing hole for fixation, thus fixing the connection between the end template 13 and the outer template 11 and the inner template 12. Then, the locking component 23 is inserted into the locking hole 31 for fixation. Subsequently, concrete is injected into the pouring cavity by the grouting equipment. After the concrete solidifies, the demolding operation is carried out. During demolding, the fixing plate 22 is driven away from the end template 13 by the driving component 21, and the fixing column 222 is pulled out from the first fixing hole and the third fixing hole, releasing the fixation of the template assembly 1. Then, the inner template 12 and the end template are manually removed to achieve demolding. Compared with the use of bolts for fixation, the use of fixing components in this application is more convenient, and the disassembly process does not require the removal of multiple bolts. The connection can be released by operating the driving component 21, making demolding simpler and faster, and improving the demolding efficiency of the precast aqueduct.
