Description

Technical Field

[0001] The present application relates to the field of photovoltaic construction technology, and in particular to a micro-cast-in-place pile precision control device and a control method for photovoltaics in mountainous areas with large slopes. Background Art

[0002] Micro-cast-in-place pile foundations are widely used in mountain photovoltaic support installations, primarily ensuring stable installation of photovoltaic equipment in complex terrain. With the development of new energy technologies, photovoltaic power generation systems are gradually expanding into diverse environments, particularly in mountainous areas with rugged terrain. Micro-cast-in-place piles, due to their flexible construction and compact footprint, have become a key option. This foundation form not only adapts to irregular terrain conditions but also effectively reduces costs and improves construction efficiency, playing a vital role in energy infrastructure development.

[0003] Currently, common practices for micro-cast-in-place pile construction in mountain photovoltaic projects include the following: 1. Relying on traditional drilling machines to prepare appropriately sized holes; 2. Inserting prefabricated steel cages into the completed holes and manually calibrating their positioning; 3. Using concrete pumps or other auxiliary tools to complete the pouring process. Furthermore, during the implementation phase, multi-point measuring instruments are required to repeatedly confirm that various parameters (such as pile center offset, top level, and overall verticality) are within design standards.

[0004] However, in actual operation, this approach was found to have significant shortcomings. Because each step required manual inspection and correction by professionals, it was time-consuming and labor-intensive, especially for large-scale projects. This directly impacted the speed of project progress, necessitating an urgent need for a more efficient solution to optimize process management and shorten construction timelines. Summary of the Invention

[0005] In order to improve the overall construction efficiency, the present application provides a micro-cast-in-place pile precision control device and control method for photovoltaic projects in mountainous areas with large slopes.

[0006] A micro-cast-in-place pile precision control device for photovoltaic systems in mountainous areas with steep slopes comprises a leveling base, a lifting mechanism is provided on the top of the leveling base, a clamping mechanism for clamping a steel cage is provided on the top of the lifting mechanism, a filling cylinder for extending into the interior of the steel cage is also connected to the top of the lifting mechanism, a lifting mechanism for controlling the lifting and lowering of the filling cylinder relative to the clamping mechanism is provided between the lifting mechanism and the filling cylinder, and a casting pipe is provided inside the filling cylinder.

[0007] By adopting this technical solution, the leveling base ensures the precise and stable position of the rebar cage during construction. The lifting mechanism allows the cage to be precisely lowered into the hole, and the clamping mechanism ensures the cage's secure position throughout the construction process. The filling cylinder assists in the smooth pouring of concrete, while the lifting mechanism effectively controls the relative movement of the filling cylinder and the pouring tube, achieving uniform pouring from bottom to top. This overall solution significantly improves construction efficiency, while ensuring the top height and center position accuracy of the bored pile, reducing the need for repeated measurements and adjustments.

[0008] The detailed process is as follows: when in use, a drilling machine is first used to drill a hole, the diameter of the hole being larger than the diameter of the steel cage, and the depth of the hole being larger than the length of the steel cage; After that, a leveling base is built according to the actual construction position of the bored pile. During the construction process, the center axis position of the steel cage is consistent with the calibrated center axis position of the bored pile. After the leveling base is installed, the steel cage with the filling tube inserted inside can be driven downward into the hole by the lifting mechanism. The specific downward distance of the lifting mechanism can be estimated based on the set height of the leveling base so that the top height of the steel cage meets the calibrated height. After that, the gap between the steel cage and the hole is filled with crushed stone to stabilize the steel cage. Then, the concrete is poured into the hole using the pouring pipe. During the pouring process, the filling cylinder and the pouring pipe are gradually lifted up by the lifting mechanism, and the concrete is poured from bottom to top.

[0009] During the entire construction process, it is only necessary to determine the center position of the steel cage and the height of the leveling base when installing the leveling base. The subsequent installation process does not require repeated measurement and adjustment at each step, so that the top height of the finally cast bored pile and the accuracy of the center position of the bored pile can be guaranteed, thus improving efficiency.

[0010] Preferably, a gravel basin is provided on the top of the lifting mechanism, the clamping mechanism is provided on the gravel basin, a clearance hole for the filling cylinder to pass through is provided at the center of the gravel basin, the lifting mechanism is provided on the gravel basin, and a stone dropping hole is provided at the bottom of the gravel basin in the circumference of the clearance hole.

[0011] By adopting this technical solution, the gravel basin is used to centrally store gravel, and the clearance holes ensure that the filling cylinder can smoothly pass through the gravel basin. At the same time, the design of the drop hole allows the gravel to fall evenly into the gap between the steel cage and the formed hole, effectively improving the efficiency and stability of the gravel filling, reducing manual intervention, and further enhancing overall construction efficiency.

[0012] Preferably, a valve plate for sealing the stone-falling hole is rotatably provided at the bottom of the gravel basin, and a control valve for controlling the opening and closing of the valve plate is provided between the valve plate and the gravel basin.

[0013] By adopting this technical solution, the controllable opening and closing of the stone drop hole at the bottom of the gravel basin is achieved. The specific effects are as follows: the valve plate and control valve precisely control the process of gravel falling from the gravel basin into the gap between the steel cage and the hole, avoiding uneven delivery caused by a one-time release. The rotating valve plate enhances operational flexibility, allowing the degree of opening and closing to be adjusted according to actual needs, further optimizing the gravel filling effect. The overall structure simplifies the construction process, ensuring accuracy while improving construction efficiency.

[0014] Preferably, the bottom wall of the gravel basin is provided with a placement groove for inserting the top of the steel cage, and the clamping mechanism is arranged in the placement groove. The placement groove includes an insertion rod and a clamping drive component. The clamping drive component is connected to the gravel basin and is used to drive the insertion rod to insert the steel cage.

[0015] By adopting the above technical solution, the clamping mechanism is set in the placement groove, which includes an insertion rod and a clamping drive. The clamping drive is connected to the gravel basin and can drive the insertion rod to insert the steel cage, thereby achieving stable fixation of the steel cage. Specifically, the placement groove provides a precise positioning space for the steel cage, ensuring the stability of the steel cage in the vertical direction; the insertion rod further enhances the gripping ability of the steel cage. In conjunction with the action of the clamping drive, the steel cage can be firmly locked in a predetermined position to prevent it from shifting or shaking during the construction process. This design effectively improves the accuracy and reliability of the steel cage installation, reduces the repeated adjustment time caused by unstable fixation, and thus improves the overall construction efficiency.

[0016] Preferably, the leveling base includes a base body, the base body is slidably connected to a ground plug, the ground plug threaded sleeve is provided with an upper adjusting nut and a lower adjusting nut, and the upper adjusting nut and the lower adjusting nut respectively abut against the top wall and the bottom wall of the base body.

[0017] By adopting the above technical solution, the leveling base can adapt to installation requirements in various terrain conditions. Specifically, the sliding connection design between the base and the ground plug allows the extension length of the ground plug to be adjusted according to the actual ground conditions, ensuring the overall horizontal state of the leveling base. At the same time, the coordinated use of the upper and lower adjustment nuts further improves the adjustment accuracy. By tightening the nuts, the height and posture of the base can be precisely controlled, effectively ensuring the consistency of the center axis position of the steel cage with the calibrated center axis position of the cast-in-place pile, reducing the repeated measurement and calibration work during the construction process and significantly improving construction efficiency.

[0018] Preferably, the middle section of the ground plug has a coaxially arranged ball head, the ball head is connected to an anti-sinking plate, the anti-sinking plate is provided with a ball socket for the ball head to be inserted into, and the anti-sinking plate is located below the seat body.

[0019] By adopting this technical solution, the anti-sinking plate can freely rotate at multiple angles through the cooperation of the ball head and the ball socket, ensuring that the anti-sinking plate always adheres to the slope surface, effectively preventing the tip of the bottom of the ground plug from sinking into the soil due to uneven force, thereby ensuring the overall stability and accuracy of the leveling base. At the same time, this structural design simplifies the leveling operation and improves construction efficiency.

[0020] Preferably, the lifting mechanism includes a lifting frame, the lifting frame is rotatably provided with a pair of squeezing rods, the lifting frame is provided with an squeezing drive for driving the squeezing rods to rotate, and the two squeezing rods clamp the top of the casting pipe.

[0021] By adopting this technical solution, the squeezing roller grips the pouring tube and rotates, squeezing the tube during rotation, thereby pushing out the concrete inside the tube and achieving pouring. Furthermore, the squeezing roller's rotation also causes the tube to move upward, achieving simultaneous lifting and pouring, improving construction efficiency and ensuring the continuity and accuracy of the pouring process.

[0022] Preferably, the lifting frame is provided with a sliding seat, the extruding roller is rotatably connected to the sliding seat, the extruding drive is connected to the sliding seat, and the lifting frame is provided with a telescopic driving member for driving the sliding seat to achieve adjustment of the distance between the two extruding rollers.

[0023] By adopting this technical solution, the sliding seat enables relative sliding between the extrusion rods and the lifting frame. The telescopic drive element allows for flexible adjustment of the spacing between the two extrusion rods. This design not only facilitates the clamping and extrusion of pouring tubes of varying diameters, but also allows for the release of pouring tubes when needed to facilitate replenishment or replacement of concrete, significantly enhancing the operational flexibility and adaptability of the equipment. Furthermore, varying the spacing between the extrusion rods directly affects the squeezing force applied to the pouring tube, optimizing construction efficiency while ensuring pouring quality.

[0024] A control method for a micro-cast-in-place pile precision control device based on photovoltaic systems in steep mountainous areas. When in use, a drilling machine is first used to drill a hole. The diameter of the hole is larger than the diameter of the steel cage, and the depth of the hole is greater than the length of the steel cage. After that, a leveling base is built according to the actual construction position of the bored pile. During the construction process, the center axis position of the steel cage is consistent with the calibrated center axis position of the bored pile. After the leveling base is installed, the steel cage with the filling tube inserted inside can be driven downward into the hole by the lifting mechanism. The specific downward distance of the lifting mechanism can be estimated based on the set height of the leveling base so that the top height of the steel cage meets the calibrated height. After that, the gap between the steel cage and the hole is filled with crushed stone to stabilize the steel cage. Then, the concrete is poured into the hole using the pouring pipe. During the pouring process, the filling cylinder and the pouring pipe are gradually lifted up by the lifting mechanism, and the concrete is poured from bottom to top.

[0025] By adopting the above technical solution, the following effects are achieved: The setting of the leveling base can ensure that the center axis of the steel cage coincides with the calibrated center axis of the cast-in-place pile, thereby improving positioning accuracy and reducing the workload of subsequent adjustments.

[0026] The use of the lifting mechanism in conjunction with the filling cylinder and the clamping mechanism simplifies the installation process of the steel cage and ensures the position accuracy of the steel cage when it descends into the hole.

[0027] The filling cylinder and the lifting mechanism work together to effectively improve the quality of concrete pouring during the bottom-up pouring process, avoiding the problems that may be caused by traditional one-time pouring.

[0028] The gravel filling process further strengthens the fixing effect of the steel cage and enhances the overall stability and bearing capacity of the structure.

[0029] In summary, this control method significantly improves the construction efficiency of photovoltaic micro-cast-in-place piles in steep mountainous areas while also ensuring construction quality.

[0030] Preferably, during the concrete pouring process, a lifting mechanism is used to control the filling cylinder and the pouring pipe to move up and down continuously as a whole, and still maintain an overall upward state.

[0031] By adopting this technical solution, the filling cylinder and pouring tube continuously move up and down during the pouring process while maintaining an overall upward position. This effectively squeezes the concrete filled into the steel cage downward, allowing the concrete to be squeezed out of the cage more evenly, improving the uniformity of the concrete entering the surrounding gravel of the cage, and significantly improving the overall density after the final pour. In addition, this dynamic up and down movement promotes the fluidity and distribution of the concrete, reducing residual bubbles and localized voids, further ensuring the quality stability and structural strength of the cast-in-place pile.

[0032] In summary, this application includes at least one of the following beneficial technical effects: 1. The coordination between the leveling base and the lifting mechanism can accurately control the position and height of the steel cage, reducing the need for repeated manual measurement and adjustment, and significantly improving construction efficiency; 2. The filling cylinder and the lifting mechanism work together to achieve precise pouring from bottom to top during the concrete pouring process, ensuring pouring quality while improving operational convenience; 3. The combination of gravel filling and steel cage fixation enhances structural stability, reduces the risk of errors caused by complex terrain, and ensures that the final pile foundation quality meets the standards.

DETAILED DESCRIPTION

[0035] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. The described embodiments are only possible technical implementations of the present invention and do not constitute a complete implementation. Those skilled in the art can fully combine the embodiments of the present invention to derive other embodiments without creative work, and these embodiments are also within the scope of protection of the present invention.

[0036] The inventors of this application found that each link in the construction of micro-cast-in-place piles requires repeated manual measurement and calibration, resulting in low overall efficiency. For this reason, this application mainly adopts a micro-cast-in-place pile precision control device for large-slope mountain photovoltaics, including a leveling base, a lifting mechanism, a clamping mechanism, a filling cylinder, a lifting mechanism and a pouring pipe and other components. The integrated design significantly reduces human intervention and improves construction efficiency and precision. The following is a further detailed description of this application.

[0037] Example 1 The embodiment of the present application provides a micro-cast-in-place pile precision control device for photovoltaic systems in mountainous areas with steep slopes, comprising a leveling base 1, the center of which is hollow. A gravel basin 2 is provided above the leveling base 1, and the middle of the gravel basin 2 is also hollow. A lifting mechanism 3 is provided between the gravel basin 2 and the leveling base 1. The lifting mechanism 3 in this embodiment is a motor combined with a screw to achieve the lifting and lowering of the gravel basin 2. A filling tube 4 is provided at the center of the gravel basin 2. The filling tube 4 is made of a plastic tube or other material, and a pouring pipe 41 is provided inside the filling tube 4. The pouring pipe 41 itself is a hose, but a section of the pouring pipe 41 located inside the filling tube 4 is fixedly connected to the filling tube 4. The edge of the gravel basin 2 is also connected to a lifting mechanism 5 through a bracket. The lifting mechanism 5 is connected to the top of the pouring pipe 41, and is used to achieve the lifting and lowering of the pouring pipe 41 and the filling tube 4 as a whole.

[0038] Reference Figure 2 and Figure 3The leveling base 1 is composed of a base body 11 made of steel plates and a steel ground plug 12. The outer surface of the ground plug 12 is galvanized to prevent rust, and the bottom is processed into a conical shape for quick insertion into the soil. The outer side of the ground plug 12 is also provided with an upper adjusting nut 131 and a lower adjusting nut 132 through a threaded sleeve. The upper adjusting nut 131 and the lower adjusting nut 132 respectively abut the top wall and the bottom wall of the base body 11. When the leveling base 1 needs to be erected on an uneven ground, the height of the ground plug 12 relative to the leveling base 1 can be adjusted according to the actual situation of each corner by adjusting the upper adjusting nut 131 and the lower adjusting nut 132 at the four corners of the leveling base 1, so as to ultimately ensure that the leveling base 1 itself is in a horizontal state. In addition, the middle section of the ground plug 12 also has an integrally formed, coaxially arranged ball head 14, and the ball head 14 is connected to an anti-sinking plate 15, and the anti-sinking plate 15 is provided with a ball socket 140 for the ball head 14 to fit in and insert, so as to realize the rotational connection of the anti-sinking plate 15 relative to the ball head 14. When installing the leveling base 1, the depth of the ground plug 12 inserted into the soil layer must be sufficient to allow the anti-sinking plate 15 to stably abut against the ground. The tip of the bottom of the ground plug 12 is prone to gradually downward after being affected by the overall gravity. In order to avoid this situation, the precise state of the leveling base 1 that has been precisely adjusted is affected by the automatic rotation characteristics of the anti-sinking plate 15, so that it can fit the slopes of different angles, so as to avoid the tip of the bottom of the ground plug 12 from sinking excessively after being subjected to force, which affects the state stability of the leveling base 1.

[0039] Reference Figure 4 The bottom wall of the gravel basin 2 is provided with a placement slot 21 for inserting the top of the steel cage 23. The placement slot 21 is arranged circumferentially along the central hollow portion of the gravel basin 2. A clamping mechanism 22 is provided on one side of the inner portion of the placement slot 21, close to the outer edge. The clamping mechanism 22 includes an insertion rod 221 and a clamping drive 222. The clamping drive 222 is connected to the gravel basin 2 and is used to drive the insertion rod 221 to insert into the steel cage 23. The steel cage 23 itself is a structure in which steel bars are tied horizontally and vertically. Therefore, the insertion rod 221 is inserted into the thick part of the wall of the steel cage 23 and pressed against it to achieve the fixation of the steel cage 23 relative to the gravel basin 2. The clamping drive 222 drives the insertion rod 221 to be withdrawn, and the steel cage 23 can be separated, which is convenient to operate.

[0040] A clearance hole 20 for the filling cylinder 4 to pass through is provided at the center of the gravel basin 2. Stone drop holes 24 are also evenly distributed around the clearance hole 20 at the bottom of the gravel basin 2. In actual practical scenarios, the gravel basin 2 is loaded with gravel of the required specifications. On the one hand, the gravel can increase the overall weight, making the leveling base 1 more stable, because wind resources are relatively abundant in mountainous areas, which can increase stability. On the other hand, the gravel can also fill the gap between the steel cage 23 and the drilled hole, thereby improving the position accuracy of the steel cage 23 after installation. Accordingly, in order to control the fall of the gravel, a valve plate 25 for covering the stone drop hole 24 is provided at the bottom of the gravel basin 2 through hinge rotation, and a control valve 26 for controlling the opening and closing of the valve plate 25 is provided between the valve plate 25 and the gravel basin 2. The control valve 26 is used to control the opening and closing of the valve plate 25 to achieve the falling and interruption of the gravel.

[0041] Reference Figure 5 The lifting mechanism 5 includes a lifting frame 51, which is slidably provided with a pair of slides 52, which are symmetrically arranged. Each slide 52 is rotatably provided with a pair of squeezing rods 53. Each slide 52 is provided with an squeezing drive, such as a motor, for driving the squeezing rods 53 to rotate. In addition, the lifting frame 51 is also provided with a telescopic drive member 55, such as a hydraulic cylinder, for driving the slide 52 to slide to adjust the distance between the two squeezing rods 53. The two squeezing rods 53 clamp the top of the pouring pipe 41. The squeezing rods 53 clamp the pouring pipe 41 and rotate. During the rotation, the pouring pipe 41 is squeezed, thereby pushing out the concrete inside the pouring pipe 41 to achieve pouring. In addition, the squeezing rods 53 clamp the pouring pipe 41 and rotate, which also causes the pouring pipe 41 to move upward, thereby achieving simultaneous lifting and pouring. During the sliding process of the squeezing rollers, in addition to adjusting the distance between the squeezing rods 53, the tightness of the squeezing rods 53 on the casting pipe 41 can also be adjusted. In addition, the two squeezing rods 53 can also be opened to pour concrete into the casting pipe 41, thereby improving the convenience of operation.

[0042] The implementation principle of the micro-cast-in-place pile precision control device for photovoltaic systems in mountainous areas with large slopes is as follows: the leveling base 1 realizes terrain-adaptive leveling through the sliding ground plug 12 and the adjusting nut; the lifting mechanism 3 drives the steel cage 23 down accurately to the hole; the clamping mechanism 22 fixes the steel cage 23 through the insertion rod 221 and the driving member; the filling cylinder 4 has a built-in casting pipe and cooperates with the lifting mechanism 5 to realize bottom-up concrete pouring. The control method includes the steps of hole preparation, construction of the leveling base 1, positioning of the steel cage 23, gravel filling and concrete pouring. The present invention solves the problems of excessive manual intervention, low efficiency and poor precision in traditional construction by integrating the leveling, clamping, gravel filling and dynamic pouring functions, significantly improving the positioning accuracy of the steel cage 23, the uniformity of concrete pouring and the construction efficiency, and is particularly suitable for environments with large slopes and complex terrains.

[0043] In addition, refer to Figures 6 to 8 The present application also discloses a control method for a micro-cast-in-place pile precision control device based on photovoltaics in steep mountainous areas: When in use, a drilling machine is first used to drill a hole 60 in the ground 6. The diameter of the hole is larger than the diameter of the steel cage 23, and the depth of the hole is larger than the length of the steel cage 23. After that, the leveling base 1 is constructed according to the actual construction position of the bored pile. During the construction process, the center axis position of the steel cage 23 is aligned with the calibrated center axis position of the bored pile. After the leveling base 1 is installed, the steel cage 23 with the filling tube 4 inserted inside can be driven downward into the hole by the lifting mechanism 3. The specific downward distance of the lifting mechanism 3 can be estimated based on the set height of the leveling base 1 so that the top height of the steel cage 23 meets the calibrated height. Then, gravel 61 is filled along the gap between the steel cage 23 and the hole to stabilize the steel cage 23. Then, the pouring pipe 41 is used to pour concrete into the hole. During the pouring process, the lifting mechanism 5 is used to gradually lift the filling cylinder 4 and the pouring pipe 41 as a whole, and pouring is performed in a bottom-up pouring manner.

[0044] During the entire construction process, it is only necessary to determine the center position of the steel cage 23 and the height of the leveling base 1 when installing the leveling base 1. The subsequent installation process does not require repeated measurement and adjustment at each step, so that the top height of the finally cast bored pile and the accuracy of the center position of the bored pile can be guaranteed, thereby increasing efficiency.

[0045] Furthermore, during the concrete pouring process, the lifting mechanism 5 is used to control the continuous upward and downward movement of the filling cylinder 4 and the casting pipe, while maintaining the overall upward position. As the filling cylinder 4 and the casting pipe move downward, the concrete filled into the steel cage 23 is pressed downward, thereby better squeezing the concrete out of the steel cage 23, thereby improving the uniformity of the concrete entering the crushed stone around the steel cage 23 and improving the overall density after the final pouring.

[0046] The solutions described in the embodiments of the present invention are only possible technical implementations of the present invention, and are not all possible implementations. Those skilled in the art can fully combine the embodiments of the present invention to obtain other embodiments without creative work, and these embodiments are also within the scope of protection of the present invention.
