Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic casting, in particular to a photovoltaic support foundation casting device. Background Art

[0002] The construction process of photovoltaic support foundation mainly includes line positioning - drilling rig placement - point re-measurement - drilling holes - drilling rig relocation - steel cage and embedded steel pipe transportation and installation - re-inspection - concrete pouring - formwork removal and maintenance.

[0003] Before pouring concrete, it is necessary to remove the waste residue in the pile hole, and then use the pouring device to cast the pouring hole in one go.

[0004] When pouring the foundation, Figure 1 As shown, there is a layout process above the casting hole, and then the ground pile (rebar cage and steel pipe) is placed in the casting hole. A short crowbar is inserted into the upper end of the ground pile. Since the ground pile is relatively low from the ground, a worker is required to bend over and hold the short crowbar with both hands, and then look down from top to bottom to see if the ground pile is horizontal and directly below the layout, so as to ensure the verticality of the ground pile. During casting, another worker is required to cooperate with the side to use a long top stick to extend into the casting hole to support the lower end of the ground pile to prevent the concrete from shaking and deviating from the ground pile during the casting process, thereby affecting the verticality and horizontality of the ground pile. If the ground pile tilts or deviates from the positioning position during casting, it will affect the subsequent installation of photovoltaic panels. In addition to these two workers, a worker is also required to be equipped a few meters away to visually inspect whether the ground pile casting is offset from the direction of the layout, because the two workers at the ground pile position are looking down at the verticality, horizontality and concentricity of the ground pile at a very close distance, which can easily cause visual errors.

[0005] Therefore, when pouring a ground pile, at least three workers are needed to complete the task, and all inspections are done by visual inspection. During the entire pouring process, short crowbars are used manually to maintain the work, and the shaking caused by pouring concrete requires constant manual adjustment of the ground pile, which brings great inconvenience to the pouring. During the pouring process, positioning and fixation are all done manually, which results in large errors, resulting in low pouring efficiency, low quality control of ground pile pouring, and a high rework rate during subsequent photovoltaic power generation installation.

[0006] On this basis, the present invention provides a photovoltaic bracket foundation casting device to solve the above technical problems. Summary of the invention

DETAILED DESCRIPTION

[0037] The above and other technical contents, features and effects of the present invention are described in detail below with reference to the attached Figures 1 to 12 The details of the embodiments will be clearly presented. The contents mentioned in the following embodiments are all based on the drawings in the specification.

[0038] Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings.

[0039] The present invention is a photovoltaic bracket foundation casting device, which is mainly used for the casting construction of pile foundation in the early stage of photovoltaic power generation installation. The environment is that it is necessary to lay out the lines on the construction site, locate the location of the prepared drilling, and start drilling the location after the point is re-measured and confirmed to be correct. After the drilling is completed, the ground pile needs to be placed in the drilled hole for casting.

[0040] The "left" and "right" directions described below in the present invention are based on the Figure 2 , Attachment Figure 4 , Attachment Figure 6 , Attachment Figure 7 , Attachment Figure 8 , Attachment Fig. 9 For reference, Figure 3 , Attachment Figure 5 , Attachment Fig.10 The "left" and "right" directions are opposite.

[0041] It includes a plurality of cast holes 1 that have been drilled, and a positioning line is arranged above the cast holes 1. Ground piles 2 (steel pipes and steel cages) are placed in the cast holes 1 for casting.

[0042] The left frame 3 and the right frame 4 are rectangular in shape as a whole, have the same structure and are symmetrically arranged. The left frame 3 and the right frame 4 are connected integrally by an upper cross bar 5 and a lower cross bar 6 at the upper and lower ends and front and back, respectively. A fixing plate 7 is integrally connected to the outer side of the lower end of the left frame 3 and the right frame 4. A fixing hole 8 is opened on the fixing plate 7, and the fixing hole 8 is fixed with bolts or pin holes.

[0043] A vertical mounting shell is fixed at the middle vertical position of the left frame 3 and the right frame 4. The interior of the mounting shell is a cavity with the upper end passing through it. A positioning rack 9 is slidably installed inside the shell. The positioning rack 9 is meshed with a positioning gear 10. The positioning gear 10 is placed in the cavity inside the left frame 3 and the right frame 4. The positioning gear 10 is coaxially connected to a first hand wheel 11 placed outside. A bearing seat is sleeved on the corresponding shaft. A U-shaped wire clamping groove 12 is fixed at the upper end of the positioning rack 9. The positioning wire that has been placed needs to pass between the two wire clamping grooves 12.

[0044] A sliding base plate 58 is integrally connected to the inner side of the upper cross bar 5, and a slide rail 59 is provided on the sliding base plate 58, so that an adjustment frame 13 is slidably installed in the left and right directions on the upper ends of the left frame 3 and the right frame 4, and a slide bar 60 that slides in the slide rail 59 is fixed to the lower end of the adjustment frame 13.

[0045] A bidirectional screw rod 14 is rotatably installed in the adjusting frame 13, and the thread directions of the two ends of the bidirectional screw rod 14 are opposite. A bearing seat is also sleeved at the position corresponding to the adjusting frame 13. A limiting light rod 15 is also fixed in the adjusting frame 13 and on one side of the bidirectional screw rod 14. A bearing seat is also sleeved at the position corresponding to the adjusting frame 13. The two ends of the bidirectional screw rod 14 are respectively threadedly connected with an arc-shaped upper clamping plate 16. The two arc-shaped upper clamping plates 166 form a circle. A through hole is provided at one end of the upper clamping plate 16, and the limiting light rod 15 passes through the through hole. The upper clamping plate 16 can slide on the limiting light rod 15, so that the upper clamping plate 16 can realize lateral movement. A locking plate is provided at the other end of the upper clamping plate 16, and a bolt hole is provided on the locking plate.

[0046] It should be emphasized that the axis of the upper clamping plate 16 is in a straight line with the middle of the wire clamping groove 12. When the positioning line has been placed through the wire clamping groove 12, it can be ensured that the diameter of the upper clamping plate 16 is located directly below the positioning line, and the center of the circle of the upper clamping plate 16 is concentric with the ground pile it clamps, which can ensure that the ground pile is directly below the positioning line.

[0047] At the same time, an adjusting sleeve 17 is fixed on the left outer side of the adjusting frame 13, and an embedded groove 18 with an inner diameter larger than the inner diameter of the adjusting sleeve 17 is opened in the adjusting sleeve 17, and a threaded hole is opened on the left frame 3 at the corresponding position, and an adjusting screw 19 is connected to the thread in the threaded hole, and one end of the adjusting screw 19 is connected to a second hand wheel 20, and a pulling plate 21 is fixed to the other end of the adjusting screw 19, and the pulling plate 21 is rotatably placed in the embedded groove 18, and no thread is set on the part of the adjusting screw 19 in the adjusting sleeve 17.

[0048] A clamping and pouring device is fixed on the lower cross bar 6, and the clamping and pouring device is used for subsequent pouring and further for clamping the ground piles. Because single-point fixation may cause the ground piles to deviate and shake while pouring concrete, a clamping and pouring device is needed to further fix the ground piles. Double-point fixation can ensure that the ground piles remain stable without shaking or deviating.

[0049] Furthermore, the clamping and casting device includes a clamping shell 22 slidably mounted on the lower cross bar 6. Specifically, the clamping shell 22 is rectangular as a whole, with a cavity inside and openings on both sides of the front end. A slide groove 51 is provided on the lower cross bar 6, and a slider 52 sliding in the slide groove 51 is fixed below the clamping shell 22. A large gear 23 is rotatably installed in the clamping shell 22, and a right pinion 24 is meshed on the right side of the large gear 23, and a reversing gear 25 is meshed on the left side of the large gear 23. The reversing gear 25 is meshed with a left pinion 26. A lower clamping plate 27 is coaxially sleeved above the left pinion 26 and the right pinion 24. The left pinion 26, the reversing gear 25, and the right pinion 24 are of the same size, so that the left pinion 26 and the right pinion 24 rotate synchronously, and the size of the large gear 23 is larger than the left pinion 26, the reversing gear 25, and the right pinion 24, so as to achieve rapid rotation.

[0050] It should be noted that the lower clamping plate 27 includes a lower rotating rod and a lower clamping plate integrally connected thereto, but the height of the lower clamping plate is greater than the lower rotating rod, the lower clamping plate is flush with the upper end surface of the lower rotating rod, and the lower clamping plate extends downward beyond the lower rotating rod and is close to the ground.

[0051] The upper end of the large gear 23 is coaxially connected to the first worm wheel 28, and the first worm gear 28 is meshed with the first worm 29 on the side. The first worm gear 29 passes through the clamping shell 22, and a bearing seat is sleeved at the corresponding position. The end of the first worm gear 29 is connected to the third hand wheel 30 placed on the outer side of the rear end of the clamping shell 22.

[0052] It should also be noted that a locking plate is also integrally extended from the other end of the lower clamping plate 27 , and a bolt hole is provided on the locking plate for achieving locking.

[0053] Furthermore, a vertical positioning groove 31 is provided in the middle outer side of the arc of each lower clamping plate 27, and the bottom of the positioning groove 31 is close to the bottom of the lower clamping plate 27. A positioning shell 32 that can be flipped outward is rotatably installed in the positioning groove 31 and is limited by friction, so it needs to rely on external force to rotate. The interior of the positioning shell 32 is a cavity with an opening at the upper end, and a positioning plate 33 is slidably installed inside it. The dimensions are marked on the positioning plate 33, and the end of the positioning plate 33 is integrally connected to a top plate that is larger than the thickness of the positioning plate.

[0054] Furthermore, a threaded hole is opened on the lower cross bar 6 on the front side, and a tightening screw 34 passes through the threaded hole. One end of the tightening screw 34 is connected to a rotating wheel, and the other end of the tightening screw 34 is movably and rotatably connected to an arc-shaped casting shell 35 with a certain elasticity. The interior of the casting shell 35 is a cavity, and casting plates 36 are slidably installed at both ends of the casting shell 35. One end of the casting plates 36 is provided with a plug 37, and the other end of the casting plate 36 is provided with a slot 38. For the convenience of description, the position here is called the front casting shell and the front casting plate.

[0055] A casting shell 35 and a casting plate 36 having the same structure as the casting shell 35 and the casting plate 36 are provided at the rear side of the lower cross bar 6, and are called a post-casting shell and a post-casting plate.

[0056] A casting shell 35 and a casting plate 36 having the same structure as the casting shell 35 and the casting plate 36 are provided at the left frame 3, and are referred to as a left casting shell and a left casting plate.

[0057] A casting shell 35 and a casting plate 36 having the same structure as the casting shell 35 and the casting plate 36 are provided at the right frame 4, and are referred to as a right casting shell and a right casting plate.

[0058] The front casting shell, the front casting plate, the rear casting shell, the rear casting plate, the left casting shell, the left casting plate, the right casting shell and the right casting plate can be connected to form a complete circle, and the position of the arc is placed at the outer diameter of the casting hole 1.

[0059] Installation grooves are provided at the rear side of the lower cross bar 6, the lower end of the left frame 3, and the lower end of the right frame 4. A reel 39 is rotatably installed in the installation groove. A pull rope 41 is wound around the reel 39 and a coil spring 40 is installed. A mounting plate is installed on the front side of the installation groove. The mounting plate is provided with a through hole for the pull rope 41 to pass through. The pull rope 41 passes through the through hole and is connected to the casting shell 35 at the corresponding position.

[0060] It should be emphasized that the casting shell 35 and the casting plate 36 have a certain elasticity, and do not need to be very elastic, such as aluminum plate, stainless steel plate (non-rigid), plastic, rubber, etc.

[0061] The casting shell 35 and the casting plate 36 are in the position of the casting hole 1 during casting. At this time, the curvature of the casting shell 35 and the casting plate 36 can form a complete circle. After the casting in the casting hole 1 is completed, it is necessary to cast a large-diameter ground on the ground outside the casting hole 1 in order to improve the strength of the casting hole 1. Therefore, at this time, it is necessary to increase the diameter of the casting shell 35 and the casting plate 36 to cast a pier, and move the casting shell 35 and the casting plate 36 outward to change the casting diameter. However, when the casting plate 36 is adjusted in sliding, it still rotates around the original center of the circle when sliding. Then, the casting plate 36 will not be able to dock to form a new large-diameter circle when sliding. Therefore, the casting shell 35 and the casting plate 36 need to have a certain elasticity so that the plug 37 and the slot 38 can be smoothly matched and docked. This elasticity only needs to meet the requirements of the plug 37 docking with the slot 38.

[0062] Furthermore, two symmetrically arranged vertical side baffles 42 are fixed at the corresponding pouring hole 1 position between the upper cross bar 5 and the lower cross bar 6 on the rear side, and a pouring bucket 43 is rotatably connected between the two side baffles 42 via a rotating shaft. When not in use, the pouring bucket 43 is vertically placed between the two side baffles 42. When pouring, the pouring bucket 43 is rotated to tilt toward the pouring hole 1. At the same time, a feeding hopper 44 is rotatably connected to the end of the pouring bucket 42, and the lower end of the feeding hopper 44 contacts the pouring shell 35. The upper end of the pouring bucket 43 is used to place a feeding pipe for pouring concrete.

[0063] Furthermore, a threaded hole is opened on the upper cross bar 5 above the two side baffles 42, and a clamping screw 45 passes through the threaded hole. A rotating wheel is fixed to the upper end of the clamping screw 45, and a clamping plate 46 is movably connected to the lower end of the clamping screw 45. The clamping screw 45 is rotated to move the clamping screw 45 downward, thereby driving the clamping plate 46 to move downward, so as to clamp the feeding pipe for pouring concrete and prevent the feeding pipe from shaking over a large range.

[0064] Furthermore, a cap 48 is provided. The cap 48 is cylindrical, has a cavity inside, and an opening at the lower end. The cap 48 is used to buckle on the upper end of the ground pile to prevent concrete from entering the steel pipe of the ground pile when pouring concrete. Hook holes 47 are provided on both sides of the front end of the feeding hopper 44. Tension springs 49 are welded on both sides of the cap 48. The tension spring 49 is fixedly connected with a draw hook 50, which can be hooked in the hook hole 47.

[0065] The cap 48 is buckled onto the upper end of the ground pile steel pipe, and at the same time, the draw hook 50 is hooked into the hook hole 47 to ensure that the inclination angle of the feeding hopper can smoothly allow the concrete to enter the pouring hole 1.

[0066] Furthermore, in addition to the cooperation of the slide groove 51 and the slider 52, a connecting rod 53 is fixed between the clamping shell 22 and the adjusting frame 13 for the sliding of the clamping shell 22, so that when the adjusting frame 13 slides, the clamping shell 22 follows the synchronous sliding, so that the upper clamping plate 16 and the lower clamping plate 27 can remain concentrically fixed when fixing the ground pile.

[0067] Furthermore, in order to ensure the stability of the upper clamping plate 16 after clamping the ground pile, an adjusting shell 54 placed between the adjusting frame 13 and the left frame 3 is fixed on the outside of the adjusting frame 13, and a second worm gear 55 and a second worm 56 are installed on the adjusting shell 54. The second worm gear 55 is meshed with the second worm 56. The second worm gear 55 is coaxially connected to the bidirectional screw 14, and the second worm 56 is coaxially connected to a fourth hand wheel 57 placed on the outside of the upper end of the adjusting shell 54.

[0068] Furthermore, in addition to the cooperation between the slide rail 59 and the slide bar 60 , the inner end of the adjustment frame 13 extends out of the sliding base plate 58 , that is, part of the adjustment frame 13 slides on the sliding base plate 58 and part of the adjustment frame 13 is placed outside the sliding base plate 58 , and this part is used to fix the connecting rod 53 .

[0069] It should also be noted that in order to ensure that the adjustment frame 13 is more accurate when adjusting the position and reduce shaking, a hydraulic shock absorber rod 61 is installed between the upper end of the adjustment frame 13 and the right frame 4. The hydraulic shock absorber rod 61 is a telescopic shock absorber rod to ensure the stability of the adjustment frame 13.

[0070] More detailed operating principles and methods: 1. Sweep the ground flat, place the whole invention above the casting hole 1, adjust the middle of the frame 13 to be roughly placed at the center of the casting hole 1, put the ground pile into the casting hole 1, and at the same time, turn the fourth hand wheel 57, the fourth hand wheel 57 drives the second worm 56 and the second worm wheel 55 to rotate, the second worm wheel 55 drives the bidirectional screw 14 to rotate, and the two upper clamping plates 16 are directed toward the ground pile steel pipe under the action of the bidirectional screw 14 with opposite threads and the limit light rod 15 to clamp the steel pipe, and then the two upper clamping plates 16 are locked with bolts from the bolt holes.

[0071] 2. Turn the first hand wheel 11 on both sides, the first hand wheel 11 drives the positioning gear 10 to rotate, the positioning gear 10 meshes with the positioning rack 9 to rise, the positioning rack 9 drives the wire clamping groove 12 to rise, so that the placed positioning line passes through the U-shaped mouth of the two wire clamping grooves 12. Since the U-shaped mouth of the wire clamping groove 12 has a sufficient height, it is not necessary for the wire clamping grooves 12 on both sides to be at the same height, only need to be roughly the same. At this time, the positioning line passes through the two wire clamping grooves 12, and the two points can form a straight line. Since the center of the upper clamping plate 16 and the middle of the wire clamping groove 12 are on the same plane, the casting hole 1, the pile steel pipe, and the positioning line are on a straight line.

[0072] 3. However, the fixation of the upper clamping plate 16 to the ground pile steel pipe is a single-point fixation, that is, there is only one fixed position, so the ground pile steel pipe may shake, deviate, or this situation may occur during the pouring of concrete. Therefore, at this time, the third hand wheel 30 is rotated, and the third hand wheel 30 drives the first worm 29 and the first worm gear 28 to rotate, and the first worm gear 28 drives the large gear 23 to rotate. The large gear 23 drives the two lower clamping plates 27 to clamp the lower end of the ground pile steel pipe through the right pinion 24, the reversing gear 25 and the left pinion 26. At this time, the clamping position is close to the ground, so the steel pipe has two fixed points, and the steel pipe will be in a vertical state without deviation.

[0073] 4. Flip the positioning shell 32 in the positioning groove 31 outward. The length of the positioning shell 32 is less than the radius of the casting hole 1. The lengths of the two positioning shells 32 are the same. Then pull out the positioning plates 33 so that one of the positioning plates 33 is attached to the inner wall of the casting hole 1. The two positioning plates 33 are pulled out to the same length. Then observe whether the other positioning plate 33 is attached to the inner wall on the other side of the casting hole 1. If it is attached, it means that the steel pipe is exactly at the center of the casting hole 1. If the other positioning plate 33 is not attached, it means that the steel pipe is eccentric to the casting hole 1 and is not in the center.

[0074] 5. Then rotate the second hand wheel 20, and the second hand wheel 20 drives the adjusting screw 19 to rotate. Since the pulling plate 21 of the adjusting screw 19 is rotatably connected with the embedded groove 18, the adjusting screw 19 can pull and push the adjusting frame 13 laterally for lateral adjustment. During the adjustment, the adjusting frame 13 drives the clamping shell 22 and the lower clamping plate 27 to move synchronously through the connecting rod 53, so that the upper clamping plate 16 and the lower clamping plate 27 drive the steel pipe to adjust synchronously. After the adjustment, continue to pull the positioning plate 33 until the positioning plates 33 pulled at both ends are the same size and all stick to the inner wall of the casting hole 1. At this time, the steel pipe is concentric with the casting hole 1 and is just below the positioning line. Then the positioning plate 33 is retracted and the positioning shell 32 is flipped back to the positioning groove 31.

[0075] 6. Turn the tightening screw 34, which is rotatably connected to the casting shell 35, so that the casting shell 35 moves toward the position of the casting hole 1, until the casting shell 35 moves to the outer diameter position of the casting hole 1 and stops, pull the casting shells 35 in the other three directions to the outer diameter of the casting hole 1, and then slide the casting plate 36, so that the plug 37 of one casting plate 36 is matched with the slot 38 of another casting plate 36 in turn. At this time, the four casting shells 35 and the casting plates 36 form a circular enclosure placed on the outer diameter of the casting hole 1.

[0076] 7. Turn over the feeding hopper 44, and then turn over the pouring hopper 43 inward so that the pouring hopper 43 and the feeding hopper 44 form an inclined surface, then buckle the cap 48 on the steel pipe to prevent concrete from being poured into the inside of the steel pipe, and then hook the hook 50 into the hook hole 47 on the feeding hopper 44 to provide stable support for the feeding hopper 44 and the pouring hopper 43.

[0077] 8. Place the feeding pipe for pouring concrete on the pouring bucket 43, and then rotate the clamping screw 45. Since the clamping screw 45 is rotatably connected to the clamping plate 46, the clamping plate 46 can be moved above the feeding pipe to fix the feeding pipe to prevent the feeding pipe from shaking widely when conveying concrete.

[0078] 9. When the pouring of the pouring hole 1 is completed, a vibrating rod is inserted into the concrete for vibration. After the vibration is completed, the concrete pier needs to be poured on the periphery of the pouring hole 1. At this time, the three pouring plates 36 are pulled outward to separate them from the circular enclosure. The pouring shell 36 is held by hand and moved outward under the action of the pull rope 41, the reel 39, and the coil spring 40 to form a large outer diameter. Then the tightening screw 34 is rotated in the opposite direction to drive the pouring shell 35 to increase the outer diameter. Since the outer diameter increases and the center of the circle deviates at this time, the sliding trajectory of the pouring plate 36 sliding therein cannot form a complete circular enclosure. Therefore, the pouring shell 35 and the pouring plate 36 have a certain elasticity, and then the plug 37 and the slot 38 of the adjacent pouring plate 36 cooperate to form a circular enclosure with a large diameter.

[0079] 10. Continue pouring inside the large diameter circular enclosure to form a circular pier for increased strength.

[0080] 11. The pouring is now completed and the reverse operation is performed to recover the entire invention.

[0081] Other things that need to be noted during the construction process are: Measuring and setting out Measure and place the cast-in-place pile foundation according to the drawings. Measure and place the position of each row of cast-in-place pile foundations in each array, as well as the pile positions and elevations at both ends of each group of cast-in-place pile foundations. Wooden piles can be used as pile fixing points and driven into the soil for fixation. At the same time, use a ruler to pull out the position of each cast-in-place pile foundation.

[0082] Drilling holes When drilling a hole with a drilling machine, the drilling machine first moves to the hole position. After the machine is tested and no faults are found, the hole position is measured and laid out, and the hole position is strictly adjusted to ensure that the hole position is vertical.

[0083] The drilling rig must not shake during the hole-making process. The drilling should be carried out layer by layer from top to bottom. The drilling speed and advancement should be strictly controlled according to the performance of the drilling rig and the actual situation of the underlying layer to prevent the hole from twisting and changing in diameter.

[0084] During the drilling process, a dedicated person should be assigned to be responsible for providing timely feedback on the drilling status of each hole and some special situations, and taking measures to complete each hole faster, more efficiently and in accordance with design requirements.

[0085] After the hole is made, inspectors are arranged to check whether the hole depth meets the design and specification requirements. If the hole collapses or the depth does not meet the design requirements, personnel are arranged to clean the hole.

[0086] Steel cage and embedded steel pipe The pile foundation reinforcement and embedded steel pipes are prefabricated according to the pile foundation size and design drawing requirements, and transported to the construction site for installation after the pile hole is formed.

[0087] Cast-in-place pile pouring 1) Before pouring concrete, the waste residue in the bored pile hole is removed, and after the steel cage is installed and corrected, the bored pile is poured using the present invention, and the bored pile is cast in one time.

[0088] 2) Control the concrete pouring speed to ensure uniform pouring, reduce the impact of concrete on the hole wall, and continuously pour to ensure that there is no broken pile, shrinkage, etc.

[0089] 3) Exposed concrete formwork engineering The cast-in-place pile is exposed by 15 cm, and the casting shell and casting plate of the present invention are used to cast the pier column.

[0090] 5. Quality control measures To avoid rust and contamination during storage and transportation, steel cages and embedded parts should be stacked in warehouses. When stacked in the open air, they should be raised and covered. During the concrete pouring process, the stability of the embedded parts should be checked in time to prevent them from shifting.

[0091] The allowable deviation of cast-in-place pile construction shall comply with the provisions in the following table: The present invention has the following technical effects: 1. The upper and lower clamping plates are used to realize the upper and lower double fixing positioning of the ground pile to ensure that the steel pipe does not deviate.

[0092] 2. Form a straight line through the two wire-clamping grooves, and then pass the positioning line through the two wire-clamping grooves. The wire-clamping groove, the upper clamping plate and the lower clamping plate are directly above the diameter of the casting hole, so it is ensured that the ground pile steel pipe must be on the diameter line of the casting hole and directly below the positioning line.

[0093] 3. Measure the distance from the inner wall of the casting hole by flipping the positioning shell and the positioning plate, and then coordinate the movement and adjustment of the frame so that the upper clamping plate and the lower clamping plate are at the center of the casting hole. At this time, the pile steel pipe is completely concentric with the casting hole and is just below the positioning line.

[0094] 4. Through the cooperation of four casting shells and casting plates as well as casting buckets and feeding hoppers, the outer baffle of the casting hole can be realized. After the casting of the casting hole is completed, the position of the casting shells and casting plates can be adjusted to realize the casting of the outer pier of the casting hole.

[0095] 5. The present invention can improve the positioning accuracy of the ground pile steel pipe and the casting hole in terms of horizontality, verticality and concentricity. The positioning no longer needs to rely on the workers' visual inspection and hand-held crowbars, which ensures the accurate positioning of the ground pile steel pipe during casting and avoids deviation, thereby affecting the subsequent installation of photovoltaic panels and causing inconvenience in work. At the same time, it does not require the cooperation of three workers, and only one person is needed to install it and watch over it on the side, which saves the workers' labor, saves time, improves casting efficiency, provides convenience for the subsequent installation of photovoltaic panels, and reduces rework.
