[0020] Before pouring, the outer formwork 1 is first built, and then the connecting steel bar 4 and the vertical steel bar 2 are tied and fixed, and a ring-shaped pouring port 6 is formed in the middle of the connecting steel bar 4. A pouring port template 39 is built inside the ring-shaped pouring port 6. The pouring port template 39 is composed of an upper ring formwork frame 7 and a lower ring formwork frame 8. The upper ring formwork frame 7 and the lower ring formwork frame 8 are both surrounded by a plurality of arc-shaped templates 12. Adjacent arc-shaped templates 12 are fixedly connected by bolts for easy assembly and fixing. After fixing, the lower ring is fixed by the diagonal brace assembly. The shaped template frame 8 is obliquely supported, and the lower annular template frame 8 below can be prevented from shifting due to the action of the oblique component. The upper annular template frame 7 is laterally supported by the side support component, and the upper annular template frame 7 can be prevented from moving through the lateral support.

[0021] The adjusting mechanism comprises a rotating cylinder 38, which is rotatably mounted on the inner top of the supporting cylinder 21. Two sets of sliding openings are provided on the outer surface of the rotating cylinder 38, and a set of sliding blocks 30 are slidably connected between the two sets of sliding openings. A first screw rod 26 is fixedly connected to the bottom of the sliding block 30, and the first screw rod 26 is rotatably connected to the inside of the adjusting shell 22 through a cross. An adjusting block 27 is screwed on the outer surface of the first screw rod 26, and a hinged plate 23 is hingedly mounted between the adjusting block 27 and the supporting plate 25.

[0022] When using the adjustment mechanism, first rotate the support cylinder 21, and then rotate the first hand wheel 19. When the first hand wheel 19 rotates, it drives the first driven bevel gear 33 to rotate. Since the first active bevel gear 34 is meshed with the first driven bevel gear 33, it drives the rotating cylinder 38 to rotate. When the rotating cylinder 38 rotates, it drives the slider 30 and the first screw rod 26 to rotate. When the first screw rod 26 rotates, it drives the adjustment block 27 to rotate. When the adjustment block 27 rotates, it can drive the support plate 25 to rotate under the action of the hinge plate 23, so that the support plate 25 can contact the placement surface. Then, the ground anchor is inserted into the socket 24, so that the lower annular template frame 8 below can be supported.

[0023] The height adjustment includes an inner gear ring 37, which is rotatably connected to the inner wall of the support tube 21, and a connecting sleeve 36 is integrally connected to the inner gear ring 37.

A threaded block 28 is screwed on the second screw rod 29, and the threaded block 28 is fixedly connected to the adjustment shell 22.

[0024] When the height of the support plate 25 needs to be adjusted, the second hand wheel 20 is rotated. When the second hand wheel 20 rotates, the second active bevel gear 32 is driven to rotate. Since the second active bevel gear 32 is meshed with the second driven bevel gear 35, the inner gear ring 37 is driven to rotate. Since the transmission gear 31 is meshed with the inner gear ring 37, the two sets of second screw rods 29 are driven to rotate. When the second screw rod 29 rotates, it will drive the adjustment shell 22 to move up and down, so that the support plate 25 can better contact the placement surface.

[0025] The first connecting arc plates 9 are fixedly connected to the upper and lower inner sides of the arc template 12 , and the second connecting arc plates 10 are fixedly connected to the inner side walls of the arc template 12 . A plurality of mounting holes 14 are provided on the first connecting arc plates 9 and the second connecting arc plates 10 .

[0026] The provided mounting holes 14 can facilitate bolt connection of the adjacent arc-shaped templates 12 above, below, or to the left and right.

[0027] The inner side of the arc-shaped template 12 is fixedly connected with a plurality of mounting mechanisms, the mounting mechanisms comprising two groups of connecting ribs 13 , and the fixing block 18 on the top of the support tube 21 is hingedly mounted between the two groups of connecting ribs 13 .

[0030] A plurality of reinforcing steel bar rings 5 ​​are formed inside the annular gate 6 , and the reinforcing steel bar rings 5 ​​are tied and fixed to the connecting steel bars 4 .

[0031] The strength of the cast structure can be improved by providing the reinforcing steel bar ring 5.

[0032] The side support assembly includes a support plate 15, which has a plurality of through holes, through which locking anchor rods are inserted, a support column 16 is fixedly connected to the support plate 15, a mounting plate 40 is fixedly sleeved on the support column 16, and a side reinforcement plate 17 is bolted between the mounting plate 40 and the arc-shaped formwork 12 on the upper annular formwork frame 7.

[0033] After the installation of the diagonal bracing assembly is completed, the side reinforcement plate 17 is installed between the support column 16 and the arc-shaped template 12 on the upper annular template frame 7, thereby supporting the upper annular template frame 7 above and improving the overall structural strength of the gate template 39.

[0034] A plurality of anti-slip protrusions are fixedly connected to the outer surface of the first hand wheel 19 and the outer surface of the second hand wheel 20 .

[0035] The adjacent left and right arc-shaped templates 12 are fixedly connected by connecting bolts, and the adjacent upper and lower arc-shaped templates 12 are fixedly connected by reinforcing bolts.

[0036] Working principle: Before pouring, first build the outer formwork 1, then tie and fix the connecting steel bar 4 and the vertical steel bar 2, form a ring-shaped pouring port 6 in the middle of the connecting steel bar 4, and build a pouring port template 39 inside the ring-shaped pouring port 6. The pouring port template 39 is composed of an upper ring formwork frame 7 and a lower ring formwork frame 8. The upper ring formwork frame 7 and the lower ring formwork frame 8 are surrounded by a number of arc-shaped templates 12. The adjacent arc-shaped templates 12 are fixed and connected by bolts for easy assembly and fixation. After fixation, the lower arc-shaped templates 12 are fixed by the diagonal brace assembly. The lower annular template frame 8 is obliquely supported. Under the action of the oblique component, the lower annular template frame 8 below can be prevented from shifting. The upper annular template frame 7 above is laterally supported by the side support component, and the upper annular template frame 7 above can be prevented from moving through the lateral support. Under the action of the side support component, the gate template 39 can be evenly stressed. Under the action of the oblique support component and the side support component, the gate mold 39 can improve the overall stability of the template, avoid the mold running and slurry leakage between the templates, and thus improve the stability of the annular gate template inside the base; When the height of the support plate 25 needs to be adjusted, the second hand wheel 20 is rotated. When the second hand wheel 20 rotates, the second active bevel gear 32 is driven to rotate. Since the second active bevel gear 32 is meshed with the second driven bevel gear 35, the inner gear ring 37 is driven to rotate. Since the transmission gear 31 is meshed with the inner gear ring 37, the two sets of second screw rods 29 are driven to rotate. When the second screw rod 29 rotates, it drives the adjustment shell 22 to move up and down, so that the support plate 25 can better contact the placement surface. When the height of the support plate 25 needs to be adjusted, the second hand wheel 20 is rotated. When the second hand wheel 20 rotates, the second active bevel gear 32 is driven to rotate. Since the second active bevel gear 32 is meshed with the second driven bevel gear 35, the inner gear ring 37 is driven to rotate. Since the transmission gear 31 is meshed with the inner gear ring 37, the two sets of second screw rods 29 are driven to rotate. When the second screw rod 29 rotates, it drives the adjustment shell 22 to move up and down, so that the support plate 25 can better contact the placement surface. After the installation of the diagonal bracing assembly is completed, the side reinforcement plate 17 is installed between the support column 16 and the arc-shaped template 12 on the upper annular template frame 7, thereby supporting the upper annular template frame 7 above and improving the overall structural strength of the gate template 39.
