Description

Technical Field

[0001] The invention relates to the technical field of concrete pile casting, and in particular to a mountain photovoltaic cast-in-place pile casting device and a casting process. Background Art

[0002] The photovoltaic support foundation is the key to ensuring the safe and normal operation of photovoltaic modules, and is the main construction content of the civil construction of photovoltaic power stations. The photovoltaic support foundation form adapted to local conditions is of great help in improving the ability of photovoltaic support power station systems to resist wind and snow loads.

[0003] Existing bored piles are divided into the following types: bored pile foundation, steel screw pile foundation, independent foundation, precast pile foundation, etc. In order to ensure the casting effect in mountainous areas, bored piles are usually used. The cost of bored piles is relatively low, and the hole is easy to make. At the same time, the elevation of the top surface of the foundation can be adjusted accordingly according to the terrain environment. Less materials are used, the construction is simple and quick, and the damage to the original terrain and surrounding vegetation is less. It is suitable for geological conditions such as clay, sand, and rock.

[0004] Therefore, when casting bored cast-in-place piles, it is necessary to embed the steel bars in advance to achieve fixation between the concrete and the steel bars. However, after the existing bored cast-in-place piles are cast, the cast-in-place piles need to be disassembled and the solidified concrete needs to be cured after the concrete solidifies. However, the shells of existing cast-in-place piles are mostly integrated structures. After the concrete solidifies, it is very difficult to disassemble the entire cast-in-place pile due to the strong adhesion of the concrete, and it is also easy to damage the surface of the solidified concrete. In addition, the existing integrated cast-in-place piles cannot adjust the internal insulation layer according to the actual temperature conditions, the concrete solidification and curing effect is not good, and the cast-in-place piles and external protective equipment are also prone to rust when exposed to extreme weather such as rain and snow for a long time. Summary of the invention

[0005] In order to overcome the problem that the bored piles with an integrated structure in the above-mentioned background technology are difficult to disassemble after the concrete solidifies, the present invention provides a mountain photovoltaic bored pile casting device and a casting process. The casting device is divided into a multi-layer structure, and each layer is composed of a plurality of side panels. After the concrete solidifies, it is easier to dismantle the blocks, which greatly reduces the damage to the concrete surface. It has the beneficial effects of clever structure and strong practicality. The distance between the side panels can be adjusted through the limiting structure and the adjusting structure, and the overall connection stability can be maintained. The internal insulation layer can also be adjusted according to the actual temperature conditions. The finished product has a good effect after the concrete solidifies.

[0011] Further preferably, the movable block is provided with a groove with a "∏"-shaped longitudinal section, a support frame is installed in the groove, the support frame is provided with an insulation layer, and the bottom of the support frame is fixedly connected to the bottom surface of the mounting groove through a magnetic block; the upper side of the arc-shaped bar body can be snapped into the fixing seat above the outer side surface of the side panel; a number of limit seats equal to the number of arc-shaped bars are provided on the base layer, and when the movable block is pulled out, the movable end of the arc-shaped bar can be inserted into the limit seat.

[0012] Preferably, a support bar is fixedly provided on the top surface of each side panel of the top seat layer along its length direction, and an upwardly protruding block is provided on the support bar. A baffle is laid on the top seat layer, and a card groove is provided on the bottom surface of the baffle. The position and shape of the card groove are matched with the card block; an annular handle is fixed in the middle of the upper surface of the baffle, and a plurality of handle grooves are evenly arranged around the annular handle.

[0013] Preferably, the inner side surface of each side panel is an arc-shaped surface structure, wherein the inner side of each side panel of the top seat layer is connected with a protective pad, the top and bottom of the protective pad respectively exceed the upper and lower surfaces of the side panels of the top seat layer, and the inner side of each side panel of the connecting layer and the top seat layer is connected with a protective plate, the top of the protective plate of the connecting layer is lower than the upper surface of the side panels of the connecting layer, and adjacent protective pads, adjacent protective plates, and adjacent protective pads and protective plates are all tightly connected; the inner walls of the protective pads and protective plates are coated with an anti-adhesion coating; the casting cavity in the connecting layer and the top seat layer is a cylindrical cavity, and the casting cavity in the base is a truncated cone cavity with an upper bottom area smaller than a lower bottom area.

[0014] Preferably, a plurality of connecting rods are evenly fixed along the circumferential direction at the bottom of the connecting layer, and an annular groove is provided at the top of the base layer, and the movable ends of the connecting rods extend into the annular groove to provide position-limiting support for the connecting layer.

[0015] Preferably, the base layer is also connected to a heat dissipation layer in the circumferential direction, and a plurality of handles and ground nails are evenly fixed to the bottom plate in the circumferential direction, and fixed to the ground by the ground nails; a bottom block is also embedded in the groove at the bottom of the base layer.

[0016] Compared with the prior art, the above technical solution has the following beneficial effects:

[0017] (1) Since the pouring device is divided into a multi-layer structure, and each layer is composed of multiple side panels, it is easier to dismantle the blocks after the concrete solidifies, which greatly reduces the damage to the concrete surface. The divided parts are also easier to transport, which solves the problem in the background technology that the integral structure of the cast-in-place pile needs to be dismantled as a whole, which is very laborious and easy to damage the surface of the solidified concrete.

[0018] (2) By adjusting the limiting structure and the adjusting structure together, the adjacent side panels of the top seat layer can be tightly connected, thereby fixing the top seat layer and maintaining the overall stability of the top seat layer.

[0019] (3) Since the bottom of the support frame in the movable block is fixedly connected to the bottom surface of the mounting groove in the side plate through the magnetic block, and a rotatable arc strip is fixed on the outside of the movable block, the movable block can be pulled out of the movable block as a whole by rotating the arc strip. The casting device after removing the movable block can not only reduce the weight of the casting device as a whole, but also allow the casting device to be ventilated in the circumferential direction, which is conducive to better forming and solidification of concrete. The movable block is inserted into the limit seat and used in conjunction with the heat insulation cloth to prevent the protective equipment and the casting device from being eroded by rain and snow and causing rust, and can also prevent the concrete from cracking when exposed to high temperature for a long time.

[0020] (4) By arranging movable blocks in each side plate of the connecting layer and placing a replaceable thermal insulation layer in the movable blocks, the thermal insulation layer can be replaced in time according to the temperature in the air, thereby improving the solidification and maintenance effects of the concrete. This solves the problem that the existing one-piece structure bored piles in the background technology cannot replace the thermal insulation layer according to the actual temperature conditions, the concrete solidification effect is poor, and the bored piles and external protective equipment are also prone to rust due to long-term exposure to extreme weather such as rain and snow.

[0021] On the basis of the above technical solution, a casting process of a mountain photovoltaic cast-in-place pile casting device is also provided, comprising the following steps:

[0022] S1: Position and install the casting device. According to the orientation, leveling point and coordinate control point of the on-site solar power station, the base layer of the casting device is fixed on the ground by rectangular coordinate method, polar coordinate method, angle intersection method or distance intersection method, and the casting device is installed;

[0023] S2: drilling with a drill rod, adjusting the drill rod angle so that the drill rod can vertically drill a hole on the ground in the casting device, cleaning the loose soil after the hole is formed, and pre-fixing the drill hole with cement;

[0024] S3: placing a steel cage and pouring concrete into it. The steel cage is placed in the pouring cavity of the pouring device, and the mixed concrete is poured into the pouring cavity to solidify the concrete and fix the steel cage into an integrally formed concrete pile.

[0025] S4: Curing concrete piles. After pouring in this pouring device for 12 to 18 hours, the concrete solidifies and the pouring device is removed. After the concrete is finished, first spray the curing agent, then use a film to cover and maintain, and then sprinkle water for maintenance every day.

[0026] The beneficial effects of this technical solution are:

[0027] The installation position of the casting device is determined by a position determination method, and then the casting device is installed. A hole is drilled in the ground inside the casting device by a drill rod, and a steel cage is placed and poured with concrete. After the concrete solidifies, the casting devices are removed one by one, and the solidified concrete piles are maintained. The concrete piles made by this casting process have accurate fixed positions and good overall stability, and can improve the quality of the finished concrete piles and their service life. They are suitable for use with mountain photovoltaic equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] Example 1: Figures 1 to 6 A mountain photovoltaic cast-in-place pile casting device shown includes a base layer 3, a connecting layer 2 and a top seat layer 1. The base layer 3, the connecting layer 2 and the top seat layer 1 are stacked together from bottom to top, and the inner walls of the three together form a casting cavity 41, that is, the base layer 3, the connecting layer 2 and the top seat layer 1 are a cavity structure, and concrete can be poured into the cavity. Each layer of the base layer 3, the connecting layer 2 and the top seat layer 1 is respectively spliced ​​by multiple sections of side panels 42, and each layer uses 3 to 6 side panels 42 to form a fence structure, wherein the number of side panels 42 of each layer is the same, and in this embodiment, each layer is spliced ​​by 4 side panels 42.

[0038] When in use, firstly, the base layer 3, the connection layer 2 and the top seat layer 1 of the pouring device are stacked one by one from bottom to top, and then the steel cage is placed in the pouring cavity 41, and the concrete transport pipe is placed on the top of the top seat layer 1 to pour concrete into the pouring cavity 41 from the opening of the top seat layer 1, and the concrete flows to the base layer 3 and flows into the drilled hole in the middle of the ground. After the pouring is completed, the concrete transport pipe is removed, and after the concrete is left to stand until it is basically solidified, the side panels 42 of each layer are disassembled one by one from top to bottom, and the concrete pile is made. Since the pouring device is divided into a multi-layer structure, and each layer is spliced ​​by multiple side panels 42, it is easier to dismantle the blocks after the concrete solidifies, which greatly reduces the damage to the concrete surface. The parts after the blocks are also easier to transport, which solves the problem that the cast-in-place piles of the integrated structure in the background technology need to be disassembled as a whole, which is very laborious and easy to damage the surface of the solidified concrete.

[0039] Embodiment 2: Based on the embodiment 1, the top seat layer 1 is preferably designed, such as Figure 2 As shown, a limiting structure 10 is arranged at the top between the adjacent side plates 42 of the top seat layer 1, such as Figure 4 As shown, the limiting structure 10 includes a limiting head 11 and a limiting plate 12. The limiting head 11 is vertically fixed to the outer end surface of the top end of the side plate 42. The limiting plate 12 is horizontally arranged between adjacent side plates 42. The limiting plate 12 is provided with a plurality of limiting holes 121 along its length direction. The limiting holes 121 are inserted into the limiting heads 11 on both sides. The limiting heads 11 can be connected to different limiting holes 121 to adjust the spacing between adjacent side plates 42 and keep the adjacent side plates 42 of the top seat layer 1 closely connected. Figure 2 As shown, an adjustment structure 13 is also arranged on the top between the adjacent side plates 42 of the top seat layer 1, such as Figure 4 As shown, the adjustment structure 13 includes an adjustment seat 14 and a screw rod 15. The adjustment seat 14 is vertically fixed to the outer end surface of the top end of the side plate 42. A threaded hole is provided in the adjustment seat 14. The screw rod 15 is horizontally arranged between adjacent side plates 42, and both ends pass through the threaded holes. The screw rod 15 is rotated to adjust the spacing between adjacent side plates 42 to keep the adjacent side plates 42 of the top seat layer 1 closely connected. Among them, the limiting structure 10 and the adjustment structure 13 are arranged at intervals at the top between the adjacent side plates 42, that is, one end of each side plate 42 of the top seat layer 1 is connected to the limiting structure 10, and the other end is connected to the adjustment structure 13.

[0040] When installing the top seat layer 1, first place the side panels 42 of the top seat layer 1 one by one on the corresponding side panels 42 of the connecting layer 2, and then the two sides of each side panel 42 of the top seat layer 1 are tightly connected with the adjacent side panels 42 through the limiting structure 10 and the adjusting structure 13 respectively. When installing the limiting structure 10, the limiting hole 121 at the appropriate position in the limiting plate 12 is inserted into the two limiting heads 11 of the adjacent side panels 42 to keep the two side panels 42 tightly connected. When installing the adjusting structure 13, rotate the screw rod 15 and pass the screw rod 15 through the threaded holes of the two adjusting seats 14 of the adjacent side panels 42 until the two side panels 42 are tightly connected. During actual use, the limiting structure 10 and the adjusting structure 13 can be adjusted repeatedly until the adjacent side panels 42 of the top seat layer 1 can be tightly connected. If the limiting structure 10 or the adjusting structure 13 is used alone, due to the limited number of limiting holes 121 of the limiting plate 12, the adjustment position is also limited, and it is impossible to ensure that each group of adjacent side panels 42 can be tightly connected. If it is only connected through the screw rod 15 of the adjusting structure 13, since the screw rod 15 needs to maintain a straight line when rotating, if each side panel 42 is connected by the screw rod 15, gaps are likely to appear between the adjacent side panels 42. In more serious cases, concrete will accumulate at the screw rod 15, making it impossible to disassemble the screw rod 15. Therefore, only through the coordinated adjustment of the limiting structure 10 and the adjusting structure 13, the adjacent side panels 42 of the top seat layer 1 can be tightly connected, thereby fixing the top seat layer 1 and maintaining the overall stability of the top seat layer 1. When the top seat layer 1 needs to be removed, the limit plate 12 is pulled out from the limit head 11, and then the screw rod 15 is rotated in the opposite direction to disengage the screw rod 15 from the threaded hole of the adjustment seat 14 on one side, and then the side plates 42 of the top seat layer 1 are removed one by one from the side plates 42 of the connecting layer 2. The block-by-block removal operation is easy and can also reduce damage to the solidified concrete.

[0041] Embodiment 3: Based on Embodiment 1, the connection layer 2 is preferably designed, such as Figures 5 and 6 As shown, each side panel 42 of the connecting layer 2 is provided with a mounting groove 21, and the mounting groove 21 penetrates the side panel 42 from the inside to the outside. A movable block 22 is connected to the mounting groove 21, and the bottom of the movable block 22 is stably connected to the mounting groove 21. A connecting seat 23 is fixed to the lower part of the outer side surface of the movable block 22, and the bottom of the arc-shaped bar 24 is inserted into the connecting seat 23. The connecting shaft 231 passes through the connecting seat 23 and the arc-shaped bar 24 to connect the two, and the arc-shaped bar 24 can rotate around the connection point, and the top of the arc-shaped bar 24 can be arranged tilted toward the outside of the side panel 42. When the movable block 22 rotates clockwise toward the inside of the side panel 42, the movable block 22 can be pulled out of the mounting groove 21 through the connecting seat 23.

[0042] Further, such as Figure 5As shown, the movable block 22 is provided with a slot 25 having a "∏"-shaped longitudinal section, and a support frame 26 is placed in the slot 25. The support frame 26 slides upward into the slot 25 from the opening at the bottom of the slot 25. The bottom of the support frame 26 is fixedly connected to the bottom surface of the mounting slot 21 in the side panel 42 through a magnetic block 261. The longitudinal section of the support frame 26 is a "]"-shaped structure, and a placement slot 27 is provided therein, and a heat insulation layer 28 is installed in the placement slot 27.

[0043] Furthermore, a fixing seat 29 is fixed to the outer side surface of the upper part of the side plate 42 of the connecting layer 2 (above the mounting groove 21 ). When the arc strip 24 is fixed, the upper side of its body can be snapped into the fixing seat 29 , further improving the connection stability between the movable block 22 and the side plate 42 .

[0044] Furthermore, if Figure 1 As shown, a plurality of limiting seats 37 are provided on the base layer 3 , the number of which is the same as that of the arc strips 24 . When the movable block 22 is pulled out, the movable end of the arc strip 24 can be inserted into the limiting seat 37 .

[0045] During use, when it is necessary to install the connecting layer 2, first put the support frame 26 with the insulation layer 28 placed on it into the slot 25 from the opening at the bottom of the movable block 22, and then put the movable block 22 into the mounting slot 21 of the side panel 42. The magnetic block 261 at the bottom of the support frame 26 is fixedly connected to the bottom surface of the mounting slot 21 by magnetic attraction. Then, the arc strip 24 is rotated upward, and the body of the arc strip 24 is inserted into the fixed seat 29 to maintain a stable connection between the movable block 22 and the side panel 42. Finally, the installed side panels 42 are placed one by one on the side panels 42 corresponding to the base layer 3, and the adjacent side panels 42 are tightly connected together. Since the top seat layer 1 is also placed above the connecting layer 2, under the action of gravity of the top seat layer 1, the side panels 42 of the connecting layer 2 that are tightly connected together are not easy to move. Therefore, there is no need to set a connecting mechanism between the side panels 42 of the connecting layer 2 to maintain the tightly connected state of the adjacent side panels 42. When the connection layer 2 needs to be removed, after the top seat layer 1 is removed, the side panels 42 of the connection layer 2 are removed one by one, and then the movable blocks 22, the support frame 26 and the heat insulation layer 28 inside are taken out in sequence.

[0046] In addition, after the concrete pouring is completed, the heat insulation layer 28 in the support frame 26 needs to be adjusted according to the temperature in the air at that time to achieve the protective effect on the concrete and ensure the quality of the finished concrete pile. Since the bottom of the support frame 26 is fixedly connected to the bottom surface of the mounting groove 21 in the side plate 42 through the magnetic block 261, the movable block 22 is rotated clockwise toward the inside of the side plate 42, and the arc strip 24 can be used to pull the movable block 22 out of the mounting groove 21 as a whole through the connecting seat 23, and then the support frame 26 is slid downward from the opening at the bottom of the slot 25 out of the slot 25, and then the heat insulation layer 28 is taken out from the side of the support frame 26 to replace the heat insulation layer 28; similarly, when the concrete needs to be poured, When the concrete is ventilated, the movable block 22 can also be pulled out of the mounting groove 21 as a whole by rotating the arc strip 24, which can not only reduce the weight of the casting device as a whole, but also enable the casting device to be ventilated in the circumferential direction, which is conducive to better forming and solidification of the concrete; in addition, after the arc strip 24 is removed, the top end of the arc strip 24 can be inserted upside down into the limit seat 37, and the heat insulation cloth can be covered on the top seat layer 1 in rainy, snowy and exposed weather. The bottom of the heat insulation cloth is tilted and supported by the top of the movable block 22, and the external protective equipment is placed under the heat insulation cloth, which can prevent the protective equipment and the casting device from being eroded by rain and snow and rusting, and can also prevent the concrete from cracking when exposed to high temperature for a long time.

[0047] Embodiment 4: Based on the embodiment 1, the top seat layer 1 is preferably designed, such as Figure 2 As shown, a support bar 16 is fixed to the outer side of the top surface of each side plate 42 of the top seat layer 1 along its length direction, and a clamping block 17 protruding upward is provided on the support bar 16, as shown in FIG. Figure 1 As shown, the top surface of the top seat layer 1 is connected with a horizontally arranged baffle 18, and the bottom surface of the baffle 18 is provided with a slot, and the opening position and shape of the slot are matched with the block 17. When the pouring device needs to be shielded, the baffle 18 is placed on the top seat layer 1, and the block 17 is aligned with the slot and embedded in the slot, so as to keep the baffle 18 stably connected to the top seat layer 1 and achieve a sealing and protective effect on the concrete. A ring handle 181 is fixed in the middle of the surface of the baffle 18, and a plurality of handle grooves 182 are evenly opened around the ring handle 181. The handle groove 182 is provided to facilitate the removal of the baffle 18.

[0048] Embodiment 5: Based on Embodiment 1, the side plate 42 is preferably designed as follows: Figure 3As shown, the inner side surface of each side panel 42 is an arc-shaped surface structure, wherein each side panel 42 of the top seat layer 1 is fixedly connected to the inner wall with a protective pad 43, the top of the protective pad 43 extends upward beyond the upper surface of the side panel 42 of the top seat layer 1, wherein the top of the protective pad 43 protrudes outward to form a protrusion 431, and the protrusion 431 is fixedly connected to the inner side of the upper surface of the side panel 42 of the top seat layer 1, and the protrusion 431 is also flush with the support bar 16 in Example 4, and supports the baffle 18 together with it, and the inner side of each side panel 42 of the connecting layer 2 and the top seat layer 1 is connected to a protective plate 44, and the setting of the protective pad 43 and the protective plate 44 can isolate the base layer 3, the connecting layer 2 and the top seat layer 1 from the internal concrete to avoid sticking to the concrete and being difficult to remove. The bottom of the protective pad 43 extends downward beyond the lower surface of the side panel 42 of the top seat layer 1, and the top of the protective plate 44 of the connecting layer 2 is lower than the upper surface of the side panel 42 of the connecting layer 2. The thickness of the protective plate 44 is greater than the thickness of the protective pad 43. When installing the top seat layer 1, the side panel 42 of the top seat layer 1 is stacked on the corresponding side panel 42 of the connecting layer 2, and its protective pad 43 will extend downward beyond the side panel 42 of the top seat layer 1 and intersect with the side panel 42 of the connecting layer 2 in height and be connected to the protective plate 44 of the connecting layer 2, that is, the top seat layer 1 and the connecting layer 2 are cross-connected. This cross-connection method can make the connection between the top seat layer 1 and the connecting layer 2 more stable.

[0049] Furthermore, adjacent protective pads 43, adjacent protective plates 44, and adjacent protective pads 43 and protective plates 44 are all tightly connected, that is, the protective pads 43 in the adjacent side panels 42 of the top seat layer 1, the protective plates 44 in the adjacent side panels 42 of the connecting layer 2, and the protective plates 44 in the adjacent side panels 42 of the base layer 3 are all tightly connected, and similarly, the upper and lower sides of the protective plates 44 of the connecting layer 2 are also tightly connected to the corresponding protective pads 43 of the top seat layer 1 and the corresponding protective plates 44 of the base layer 3, respectively, to prevent the concrete from flowing out from the gaps at the joints before solidification, causing concrete loss and damaging the outer components, wherein the top surface of the protective plates 44 of the connecting layer 2 is flush with the inner side of the connection point of the protective pads 43 of the top seat layer 1, and similarly, the bottom surface of the protective plates 44 of the connecting layer 2 is flush with the connection point of the protective plates 44 of the base layer 3, which is beneficial for the concrete to maintain a good shape after solidification and can also prevent concrete loss.

[0050] Furthermore, the inner walls of the protection pad 43 and the protection plate 44 are coated with an anti-adhesion coating, and the anti-adhesion coating is selected from polymer coating or silicate coating. The use of the anti-adhesion coating can better solve the problem of easy adhesion of concrete.

[0051] Furthermore, the casting cavity 41 in the connecting layer 2 and the top seat layer 1 is a cylindrical cavity, and the casting cavity 41 in the base is a truncated cone cavity with an upper bottom area smaller than a lower bottom area. By setting the upper part of the casting cavity 41 to a cylindrical shape and the bottom to a truncated cone shape, it is more conducive to the solidification of the concrete pile into a standard shape after casting.

[0052] Embodiment 6: Based on Embodiment 1, the connection method of the connection layer 2 is optimally designed, such as Figure 3 As shown, a number of vertically arranged connecting rods 20 are evenly fixed along the circumferential direction at the bottom of the connecting layer 2, and an annular groove 31 is provided at the top of the base layer 3. The movable end of the connecting rod 20 extends into the annular groove 31 to provide limited support for the connecting layer 2. When installing the connecting layer 2, the position of the side panels 42 of the connecting layer 2 can be adjusted at any time so that adjacent side panels 42 can be closely connected. During adjustment, the connecting rod 20 slides in the annular groove 31 to keep the side panels 42 of the connecting layer 2 stably connected to the base layer 3.

[0053] Embodiment 7: Based on Embodiment 1, the base layer 3 is preferably designed as follows: Figure 1 to Figure 2 As shown, the base layer 3 is also connected to the heat dissipation layer 32 in the circumferential direction, that is, each side plate 42 of the base layer 3 is fixedly connected with a section of the heat dissipation layer 32, and the heat dissipation layer 32 is a block structure made of aluminum and heat-resistant plastic, and its shape is matched with the connection of the base layer 3. By setting the heat dissipation layer 32, the overall weight of the base layer 3 can be reduced, the separation effect is convenient, and the internal concrete can be better promoted to conduct heat and dissipate heat to the outside.

[0054] Furthermore, the outer side of the bottom of the base layer 3 protrudes outward to form a bottom plate 33, that is, a section of the bottom plate 33 is fixed integrally to the bottom of each side plate 42 of the base layer 3, and a plurality of handles 34 and ground nails 35 are arranged on the bottom plate 33, and the handles 34 and ground nails 35 are evenly arranged around the bottom plate 33. When installing the base, first splice the side plates 42 of the base so that the adjacent protective plates 44 in the base are tightly connected, and then the ground nails 35 are knocked to move the ground nails 35 downward, and the cooperation between the ground nails 35 and the ground is used to achieve the fixing effect of the base layer 3, and the positioning of the casting device as a whole is achieved, and the base layer 3 can be removed by pulling out the ground nails 35 upward. After fixing the base layer 3, the connection layer 2 and the top seat layer 1 are installed one by one. Since the side panels 42 of the base layer 3 and the top seat layer 1 are fixed in position by connecting pieces, and the connection layer 2 is between the base layer 3 and the top seat layer 1 and keeps a stable connection with the two, the side panels 42 of the connection layer 2 can keep in position without other connecting pieces. An annular groove is provided at the bottom of the base layer 3, and a bottom block 36 is also embedded in the groove. By further splitting the side panels 42 of the connection layer 2, it is more convenient to remove the base layer 3.

[0055] Embodiment 8: Based on the technology of the above embodiment, this embodiment also provides a casting process of a mountain photovoltaic cast-in-place pile casting device, comprising the following steps:

[0056] S1: Position and install the casting device. Determine the approximate installation position of the casting device according to the orientation of the on-site solar power station, leveling points and coordinate control points. Then determine the specific fixed position of the base layer 3 of the casting device on the ground by the rectangular coordinate method, polar coordinate method, angle intersection method or distance intersection method. Fix the side panels 42 of the base layer 3 at the corresponding positions by ground nails 35. The rectangular coordinate method, polar coordinate method, angle intersection method and distance intersection method are all different methods used in the prior art to determine the position of an object. The most appropriate method can be selected for positioning according to factors such as the form of the on-site control network, terrain conditions, on-site conditions and accuracy requirements. Determine the installation position of the casting device. Then install the base layer 3, connection layer 2 and top seat layer 1 of the casting device in sequence from bottom to top, and make the internal protective plate 44 and protective pad 43 closely connected.

[0057] S2: Drilling with a drill rod. The construction is arranged according to the on-site terrain and equipment deployment. The drill rod angle is adjusted so that the drill rod can vertically drill a hole in the ground inside the pouring device. After the hole is formed, the loose soil is cleaned and the drilled hole is fixed and pre-treated with cement to facilitate the subsequent formation of the concrete pile to be firmly fixed on the ground.

[0058] S3: placing a steel cage and pouring concrete into it. The steel cage is placed in the pouring cavity 41 of the pouring device, and the mixed concrete is poured into the pouring cavity 41, so that the concrete solidifies and the steel cage is fixed as a whole to form a concrete pile, thereby enhancing the overall stability of the concrete pile;

[0059] S4: Curing concrete piles. After the concrete solidifies 12 to 18 hours after pouring, remove the pouring device. In areas with dry climates, it can be removed in advance for maintenance. After the concrete piles are finished, spray the curing agent first, then use a film to cover and maintain, and then sprinkle water every day for maintenance, but do not sprinkle too much water to soak the low-lying areas. By curing the concrete piles after solidification and removing the pouring device, the quality of the finished concrete piles can be improved, and their service life can be increased, which can be more suitable for use with mountain photovoltaic equipment.

[0060] Therefore, the installation position of the casting device is first determined by the position determination method, and then the casting device is installed. A hole is drilled in the ground inside the casting device through a drill rod, and a steel cage is placed and poured with concrete. After the concrete solidifies, the casting devices are removed one by one, and the solidified concrete piles are maintained. The concrete piles made by this casting process have accurate fixed positions and good overall stability, and can improve the quality of the finished concrete piles and their service life. It is suitable for use with mountain photovoltaic equipment.

[0061] The above embodiments only express the specific implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the protection scope of the present application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the technical solution concept of the present application, and these all belong to the protection scope of the present application.
