[0030] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation of the present invention.

[0031] The photovoltaic support anchored foundation 100 according to an embodiment of the present invention will be described below with reference to the drawings.

[0032] As Figures 1-6 shown, the photovoltaic support anchored foundation 100 according to an embodiment of the present invention includes a raft foundation 1, a column 2, and an anchored foundation 31.

[0033] The raft foundation 1 includes a raft foundation steel reinforcement cage 11 and a first matrix 12. The first matrix 12 is a concrete matrix cast on the outer peripheral surface of the raft foundation steel reinforcement cage 11 on site. Specifically, as Figure 1 shown, the raft foundation steel reinforcement cage 11 is made of high-strength steel. The first matrix 12 is a rectangular matrix formed by casting concrete on the outer peripheral surface of the raft foundation steel reinforcement cage 11, which not only strengthens the overall rigidity of the raft foundation 1, but also improves the resistance to environmental erosion of the raft foundation 1 and extends the service life of the raft foundation 1.

[0034] The column 2 is provided on the raft foundation 1 and is adapted to be connected to the photovoltaic panel support to support the photovoltaic panel support. The column 2 includes a column steel reinforcement cage 21 and a second matrix 22. The column steel reinforcement cage 21 is provided on the raft foundation steel reinforcement cage 11 and is connected to the raft foundation steel reinforcement cage 11. The second matrix 22 is a second matrix cast on the outer peripheral surface of the column steel reinforcement cage 21 on site. Specifically, as Figure 1As shown, the column steel reinforcement cage 21 is made of high-strength steel, and the connection method between the lower end of the column steel reinforcement cage 21 and the pile cap steel reinforcement cage 11 adopts mechanical connection or welding technology, ensuring the stability of the overall structure of the column steel reinforcement cage 21 and the pile cap steel reinforcement cage 11. The second matrix 22 is a column formed by pouring concrete on the outer peripheral surface of the column steel reinforcement cage 21 and extending in the up and down directions. The second matrix 22 not only enhances the compressive and bending resistance of the column 2, but also the first matrix 12 and the second matrix 22 are concrete matrices poured together on site, so that the combination of the second matrix 22 and the first matrix 12 further improves the stability of the entire system.

[0035] The anchor rod foundation 31 is arranged below the pile cap 1. The anchor rod foundation 31 includes a first anchor bar 31 and a third matrix 32. The first anchor bar 31 is adapted to be inserted into the anchor hole and the upper end of the first anchor bar 31 extends out of the anchor hole and is connected to the pile cap steel reinforcement cage 11. The third matrix 32 is a concrete matrix poured on site between the outer peripheral surface of the first anchor bar 31 and the anchor hole. Specifically, as Figure 1 shown, the anchor hole is a hole pre-drilled or punched for fixing the anchor cable, anchor rod or other anchor fittings. The first anchor bar 31 is made of high-strength material and is implanted into the preset anchor hole through precise drilling technology. The upper end of the first anchor bar 31 passes through the anchor hole and is welded to the pile cap steel reinforcement cage 11. Thus, a continuous support system from the ground to the underground is formed, greatly enhancing the uplift resistance and the performance of resisting lateral forces of the entire photovoltaic support. The third matrix 32 is a matrix formed by pouring concrete in the anchor hole. The third matrix 32 not only tightly wraps the anchor rod, strengthens the anchoring effect, but also effectively seals the anchor hole, prevents moisture and soil erosion, and extends the service life of the anchor rod.

[0036] For the photovoltaic support anchor rod foundation 100 of the embodiment of the present utility model, first, the anchor hole required for the anchor rod is drilled on site. After the first anchor bar 31 is installed in the anchor hole, the first anchor bar 31 is poured with concrete to form the third matrix 32. Then, the pile cap steel reinforcement cage 11 and the column steel reinforcement cage 21 are assembled on site. After the pile cap steel reinforcement cage 11 and the column steel reinforcement cage 21 are installed, the pile cap steel reinforcement cage 11 and the column steel reinforcement cage 21 are poured with concrete to form the first matrix 12 and the second matrix 22 respectively.

[0037] The photovoltaic bracket anchor foundation 100 of the utility model embodiment is provided with a cap 1, a column 2, and an anchor foundation 31. It only needs to transport the steel required for the anchor, the cap steel frame 11 and the column steel frame 21, as well as the equipment for digging anchor holes. Compared with the use of pile foundation related technologies, there is no need to use large-scale construction machinery for construction, and the transportation of piling machinery is eliminated. There is no need to build roads to allow the machinery to go up the mountain, which reduces the transportation cost. In addition, the diameter of the anchor hole required for the anchor foundation 31 is small, and only an anchor drill is required for drilling. Compared with the manual excavation or blasting construction method, the construction period is short, the construction safety performance is high, and the installation and production cost is low.

[0038] In some embodiments, the anchor foundation 31 further includes a positioning steel bar 4, which is disposed between the first anchor bar 31 and the anchor hole and abuts against the outer circumference of the first anchor bar 31 and the inner circumference of the anchor hole, so that the positioning steel bar 4 positions the first anchor bar 31. Specifically, Figure 1 , Figure 5 and Figure 6 As shown, the positioning steel bar 4 is an arc-shaped smooth round positioning bar, which is sleeved on the first anchor bar 31 and arranged in the anchor hole. The outer circumference of the positioning steel bar 4 and the inner circumference of the anchor hole are against each other, so that the positioning steel bar 4 positions the first anchor bar 31 to ensure that the position of the first anchor bar 31 will not deviate during the pouring of concrete, and ensure that the anchor rod maintains a vertical or predetermined angle during the installation process, avoiding uneven force or structural safety hazards caused by installation deviation.

[0039] In some embodiments, there are multiple positioning steel bars 4, and the multiple positioning steel bars 4 are arranged on the first anchor bar 31 at intervals along the vertical direction. Figure 1 As shown, the positioning steel bars 4 can be two (such as Figure 1 As shown in the two figures, one positioning steel bar 4 is arranged adjacent to the upper end of the first anchor bar 31, and the other positioning steel bar 4 is arranged adjacent to the lower end of the first anchor bar 31. Thus, by arranging the positioning steel bars 4 at different heights of the first anchor bar 31, it is not only ensured that the first anchor bar 31 remains in a vertical state during concrete pouring to avoid deflection, thereby improving the vertical bearing capacity and stability of the entire foundation structure, but also can better disperse the load applied to the first anchor bar 31, avoid local stress concentration, reduce the risk of bending of the first anchor bar 31 during the force-bearing process, and enhance its tensile and shear resistance.

[0040] In some embodiments, the third base 32 includes a first section 321 and a second section 322. The first section 321 is arranged below the second section 322. In a projection plane orthogonal to the up and down direction, the projection of the second section 322 is located in the first section 321. The first anchor bar 31 is arranged in the first section 321 and the second section 322. Specifically, Figure 1As shown, the anchor hole has a first part and a second part that communicate with each other. The aperture of the first part is larger than that of the second part, and the first part is located below the second part. After the first anchor bar 31 is inserted into the first part and the second part, concrete is poured into the first part and the second part. The first section 321 is a variable-diameter part and is formed in the first part, and the second section 322 is formed in the second part. Thus, the uplift and compressive bearing capacities of the anchor foundation 31 of the anchor bar foundation 31 are improved through the second section 322.

[0041] In some embodiments, the anchor bar foundation 31 further includes a plurality of second anchor bars 33. The plurality of second anchor bars 33 are all welded to the upper end portion of the first anchor bar 31. The plurality of second anchor bars 33 are arranged at intervals along the circumferential direction of the first anchor bar 31, and the plurality of second anchor bars 33 are arranged within the bearing platform steel bar framework 11. Specifically, as Figure 2 and Figure 3 shown, the plurality of second anchor bars 33 are welded to the outer peripheral surface of the first anchor bar 31 at equal intervals along the circumferential direction of the first anchor bar 31, and the first anchor bar 31 and the second anchor bars 33 extend into the bearing platform steel bar framework 11 and are welded to the bearing platform steel bar framework 11. Thus, the overall connection strength between the bearing platform 1 and the foundation is enhanced through the plurality of second anchor bars 33, the bearing capacity of the bearing platform 1 is enhanced, while ensuring the bearing capacity of the bearing platform 1, the height of the bearing platform 1 will be reduced, and the spaced arrangement of the plurality of second anchor bars 33 is also beneficial to the full pouring of concrete, ensuring the close combination between the concrete and the anchor bar, and improving the durability of the anchoring area.

[0042] In some embodiments, there are a plurality of anchor bar foundations 31. The plurality of anchor bar foundations 31 are arranged at intervals along the length direction of the bearing platform 1 (such as the left-right direction as shown in Figure 1 ) below the bearing platform 1, and the plurality of anchor bar foundations 31 are all connected to the bearing platform 1. Specifically, as Figure 1 shown, there are three anchor bar foundations 31 (such as the three shown in Figure 1 ). The three anchor bar foundations 31 are arranged at intervals in the left-right direction below the bearing platform 1 and are connected to the bearing platform 1. Thus, the load on the bearing platform 1 is evenly distributed into the foundation through the plurality of anchor bar foundations 31, avoiding local foundation overload, reducing the risk of foundation settlement or uneven deformation, and improving the stability and bearing capacity of the photovoltaic support anchor bar foundation 100.

[0043] In some embodiments, the bearing platform steel bar framework 11 includes a first main steel bar 111, a second main steel bar 112, a supporting bar 113, and a web bar 114. The first main steel bar 111 and the second main steel bar 112 are arranged at intervals in the up-down direction. The supporting bars 113 are all arranged between the first main steel bar 111 and the second main steel bar 112 and are respectively connected to the first main steel bar 111 and the second main steel bar 112. The web bars 114 are arranged between the first main steel bar 111 and the second main steel bar 112 and are connected to the supporting bars 113. Specifically, as Figure 1As shown, the first main reinforcement bars 111 and the second main reinforcement bars 112 are arranged alternately along the vertical direction (up and down direction) of the pile cap 1. Such a layout can effectively disperse the vertical loads borne by the pile cap 1, such as the weight of the superstructure and the reaction force from the ground. The spaced arrangement ensures effective stress transfer between the steel bars while maintaining a reasonable spacing between the steel bars, which is conducive to the full wrapping of concrete and enhances the bond performance between the steel bars and the concrete. Through the collaborative work of the various steel bars in the pile cap steel bar framework 11, a strong system is formed that can resist both vertical loads and effectively cope with horizontal loads. The first main reinforcement bars 111 and the second main reinforcement bars 112 are responsible for bearing the vertical forces, and the erection bars 113 and the web bars 114 strengthen the resistance of the structure in the horizontal and shear directions. The combination of the four enhances the load-bearing capacity of the pile cap 1 for complex loads and ensures the long-term safety and durability of the structure.

[0044] In some embodiments, the column 2 includes a first column 23 and a second column 24. The first column 23 and the second column 24 are both provided on the pile cap 1 and are spaced relatively along the length direction of the pile cap 1. The heights of the first column 23 and the second column 24 are different in the up and down direction so that the photovoltaic panels can be inclinedly installed on the first column 23 and the second column 24. Specifically, as Figure 1 shown, the number of columns 2 can be two, namely the first column 23 and the second column 24. The first column 23 and the second column 24 are spaced along the left and right direction on the pile cap 1, and the heights of the first column 23 and the second column 24 can be set according to the actual situation (the orientation and inclination angle of the photovoltaic panel), so that the photovoltaic panel can be installed at an ideal inclination angle, reducing the light loss caused by the change of the solar altitude angle and significantly improving the photoelectric conversion efficiency.

[0045] In some embodiments, the column steel bar framework 21 includes a plurality of third main reinforcement bars 211 and a plurality of stirrups 212.

[0046] A plurality of third main reinforcement bars 211 all extend along the up and down direction, and the lower ends of the plurality of third main reinforcement bars 211 are connected to the pile cap steel bar framework 11. The plurality of third main reinforcement bars 211 are spaced along the circumferential direction of the column 2. Specifically, as Figure 1 shown, the third main reinforcement bars 211 are high-strength steel bars extending along the up and down direction to provide the main compressive and tensile strength of the column 2. The plurality of third main reinforcement bars 211 are equally spaced along the circumferential direction of the column 2, which can ensure the uniform stress and structural balance of the column 2 in all directions. Moreover, the connection of the lower ends of the third main reinforcement bars 211 to the pile cap steel bar framework 11 (such as welding, fastener connection) ensures the effective force transfer between the column 2 and the pile cap 1, helps to evenly distribute the load of the superstructure to the pile cap 1, and thus enhances the stability of the entire column 2 structure system.

[0047] In some embodiments, a plurality of stirrups 212 are arranged at intervals in the up-down direction, and a plurality of third main reinforcements 211 are all inserted into the stirrups 212 and connected to the third main reinforcements 211. Specifically, as Figure 1 shown, a plurality of stirrups 212 are arranged at intervals in the up-down direction, and all the third main reinforcements 211 are inserted into the stirrups 212 and tied together with wire (in other words, the stirrups 212 form a closed loop structure around the third main reinforcements 211). Thus, by the stirrups 212, the lateral restraint force of the column 2 is enhanced, not only the shear strength of the column 2 is enhanced, but also the toughness of the overall structure is improved, so that the column 2 can better maintain its shape under the stress state, preventing the column 2 from shear failure when subjected to lateral forces (such as wind load, seismic force), and at the same time reducing the generation of cracks.

[0048] In some embodiments, the photovoltaic support anchor foundation 100 further includes a mounting member 5. The mounting member 5 is provided on the column 2 and at least part of the mounting member 5 extends out of the upper end of the column 2, and the photovoltaic support can be inserted into the mounting member 5. Specifically, as Figure 1 shown, the mounting member 5 can be a steel pipe (square steel pipe, round steel pipe), or a steel section (angle steel, channel steel, I-beam, etc.), and the corresponding steel section form can be selected according to the steel structure type of the upper support. The lower end of the mounting member 5 is embedded in the second base body 22 of the column 2, and the upper end of the mounting member 5 extends out of the second base body 22. The photovoltaic support can be inserted into the mounting member 5 and connected by embedded anchor bolts. Thus, the mounting member 5 provides a passing channel for the photovoltaic support, ensuring the stable connection between the photovoltaic support and the foundation, and also facilitating the installation and adjustment of the support. Especially when it is necessary to adjust the height of the support or perform maintenance, the reserved part of the steel pipe provides the necessary operating space.

[0049] In some embodiments, there are a plurality of first anchor bars 31, and the plurality of first anchor bars 31 are welded into a whole. Thus, through the plurality of first anchor bars 31, the anchoring ability of the anchor bolt assembly in the deep underground can be significantly enhanced, the load of the upper structure can be effectively transmitted and dispersed, and the stability of the anchor bolt assembly is improved.

[0050] It should be noted that the photovoltaic support anchor foundation 100 of the embodiment of the present invention can be used for the support foundation construction of mountain photovoltaic power stations, or for foundations with thin upper covering layers and underlying weathered rocks, or for the support foundation construction of photovoltaic power stations with high requirements for environmental protection and short construction periods, or for infrastructure fields such as industrial and civil construction, road and bridge construction, communication equipment, and power construction, or for foundation positions of photovoltaic power stations with a certain thickness of overlying soil layer and underlying weathered rocks. It is applicable to various terrains such as flat land, hills, and mountains, but the advantages in mountainous areas are greater. For photovoltaic power stations located in mountainous areas, the geological conditions generally have a thin upper soil layer and underlying weathered rocks, or are basically in a state of exposed bedrock. The terrain conditions generally have a large slope, mostly in the slope range of 20 - 35 degrees. From the perspective of construction period and construction safety, mechanized operation will greatly compress the construction period and thus reduce construction risks; from the perspective of environmental protection and water conservation, the original soil foundation needs to be considered to minimize the damage to the surrounding environment and reduce soil erosion; from the perspective of economic benefits, the characteristics of rocks or the original soil itself can be fully utilized to reduce the foundation engineering quantity, and a significant optimization of the engineering quantity can be achieved; from the perspective of adapting to terrain and light, the coordination with terrain and light angles can be achieved by setting steel structure supports or high and low main column foundations. Thus, a photovoltaic support anchor foundation 100 can comprehensively cover the above-mentioned problems or difficulties and achieve all benefits of safety, economy, and environmental protection.

[0051] In summary, (1) The photovoltaic support anchor foundation 100 of the embodiment of the present invention can make full use of the mechanical properties of the rock itself to reduce the material quantity of the foundation itself, so as to minimize the size of the foundation, and achieve comprehensive advantages such as reduced operation risks, shortened construction period, and high economic benefits.

[0052] (2) The photovoltaic support anchor foundation 100 of the embodiment of the present invention can fully realize mechanized construction. Due to the "miniaturization" and "lightweight" of the construction equipment, the construction efficiency can be greatly improved and the construction risk can be reduced when constructing in mountainous areas;

[0053] (3) The size of the foundation cap 1 of the photovoltaic support anchor foundation 100 of the embodiment of the present invention is small, which also effectively reduces the excavation area of the rock / soil body. "Using rock instead of formwork" effectively reduces the usage amount of casting formwork; "enlarged heads" are arranged at intervals in the middle and bottom of each anchor rod, which can increase the overall anti-pulling bearing capacity of the anchor rod and the foundation, and has an obvious effect on reducing the foundation material quantity;

[0054] (4) The arrangement of the first column 23 and the second column 24 of the photovoltaic support anchor foundation 100 according to the embodiments of the present invention can fully adapt to various terrains, that is, all terrains such as flat land, hilly land, and mountainous land are applicable, but the advantages in mountainous areas are greater. In this way, the amount of foundation excavation can be effectively reduced; the rigid base of high and low concrete columns replaces the flexible support of high and low steel structures, effectively increasing the safety of the overall photovoltaic system.

[0055] In this way, this foundation type can significantly shorten the construction period, reduce the project investment cost, reduce the construction risk, be suitable for mechanized construction, and at the same time be beneficial to soil and water conservation and environmental protection.
