[0029] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0030] The mountain anchor foundation 100 according to an embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0031] As Figure 1-6 shown, the mountain anchor foundation 100 according to an embodiment of the present utility model includes a bearing platform 1, a pre-embedded steel pipe 2, and an anchor foundation 3.

[0032] The bearing platform 1 includes a steel bar framework 11 and a first base body 12. The first base body 12 is a concrete base body cast on the outer peripheral surface of the steel bar framework 11 on site. The bearing platform 1 extends in the horizontal direction and slopes downward from top to bottom. Specifically, as Figure 1 shown, the steel bar framework 11 is a rectangular steel bar framework made of high-strength steel, extending from left to right and sloping upward from bottom to top. The first base body 12 is a rectangular base body formed by casting concrete on the outer peripheral surface of the steel bar framework 11. The cast-in-place first base body 12 not only ensures the firm combination of the foundation with the ground surface, but also enhances the overall stiffness of the bearing platform 1, improves the resistance to environmental erosion of the bearing platform 1, and the inclination angle of the bearing platform 1 is set according to the mountain slope (for example: the inclination angle of the bearing platform 1 is equal in size and the same in direction as the inclination angle of the mountain slope). The inclined design of the bearing platform 1 can not only conform to the terrain, fully adapt to various terrains, but also adjust the light angle in combination with the high and low steel structures embedded in the bearing platform, and can also promote rainwater drainage to a certain extent, reduce the scouring and erosion of rainwater on the foundation, and extend the service life of the bearing platform 1.

[0033] The pre-embedded steel pipe 2 extends in the up and down direction, and the lower end of the pre-embedded steel pipe 2 is inserted into the first base body 12. The upper end of the pre-embedded steel pipe 2 is adapted to be connected to the photovoltaic support. Specifically, as Figure 1 shown, the pre-embedded steel pipe 2 is a square steel pipe or a round steel pipe extending in the up and down direction. The pre-embedded steel pipe 2 can also be a section steel (for example: angle steel, channel steel, I-beam). The lower end of the pre-embedded steel pipe 2 can be connected to the steel bar framework 11 (for example: welding, fastener connection). The upper end of the pre-embedded steel pipe 2 can be installed with a photovoltaic support, thereby providing an installation foundation for the photovoltaic support.

[0034] The anchor foundation 3 is arranged below the bearing platform 1. The anchor foundation 3 includes a first anchor bar 31 and a second base body 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 steel bar framework 11. The second base body 32 is a concrete base body cast on site between the first anchor bar 31 and the anchor. Specifically, as Figure 1As shown, the anchor hole is a hole pre-drilled or bored for fixing anchor bars or other anchor fittings. The first anchor bar 31 is made of high-strength material and implanted into the preset anchor hole through precise drilling technology. The upper end of the first anchor bar 31 penetrates out of the anchor hole and is welded to the steel bar skeleton 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 second matrix 32 is a matrix formed by pouring concrete into the anchor hole. The second matrix 32 not only tightly wraps the anchor rod, strengthening the anchoring effect, but also effectively seals the anchor hole, preventing moisture and soil erosion, prolonging the service life of the anchor rod, and further enhancing the combination of the anchor rod and the surrounding soil, improving the uplift resistance and overall stability of the entire foundation.

[0035] In the mountainous area anchor foundation 100 of the embodiment of the present utility model, first, the anchor hole required for the first anchor bar 31 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 second matrix 32. Then, the steel bar skeleton 11 and the embedded steel pipe 2 are assembled on-site. After the steel bar skeleton 11 and the embedded steel pipe 2 are installed, the steel bar skeleton 11 and the embedded steel pipe 2 are poured with concrete to form the first matrix 12.

[0036] For the mountainous area anchor foundation 100 of the embodiment of the present utility model, the cap 1, the embedded steel pipe 2, and the anchor foundation 3 are provided. Only the steel materials required for the anchor rods, the steel bar skeleton 11, and the embedded steel pipe 2, as well as the machinery for anchor hole excavation, etc. need to be transported. Compared with the related pile foundation technology, there is no need to use large construction machinery for construction, eliminating the transportation of pile driving machinery, and there is no need to build roads for the machinery to go up the mountain, reducing the transportation cost. In addition, the diameter of the anchor hole required for the anchor foundation 3 is small, and only an anchor rod drilling rig is needed for drilling. Compared with the method of manual excavation or blasting construction, the construction period is short, the construction safety performance is high, and the installation and production cost is low.

[0037] In some embodiments, there are multiple anchor foundations 3. The multiple anchor foundations 3 are spaced along the length direction of the cap 1 (such as Figure 1 the left-right direction shown) and arranged below the cap 1. The multiple anchor foundations 3 are all connected to the cap 1. Specifically, as Figure 1 shown, there are three anchor foundations 3 (such as Figure 1 the three shown). The three anchor foundations 3 are spaced along the left-right direction and arranged below the cap 1 and connected to the cap 1. Thus, the load on the cap 1 is evenly distributed to the foundation through the multiple anchor foundations 3, avoiding local foundation overload, reducing the risk of foundation settlement or uneven deformation, and improving the stability and bearing capacity of the mountainous area anchor foundation 100.

[0038] In some embodiments, the anchor foundation 3 includes a first anchor foundation 33, a second anchor foundation 34, and a third anchor foundation 35. The first anchor foundation 33, the second anchor foundation 34, and the third anchor foundation 35 are arranged at intervals along the length direction of the bearing platform 1, and the first anchor foundation 33, the second anchor foundation 34, and the third anchor foundation 35 are all connected to the bearing platform 1. The first anchor foundation 33 is higher than the second anchor foundation 34, and the second anchor foundation 34 is higher than the third anchor foundation 35. Specifically, as Figure 1 shown, the first anchor foundation 33, the second anchor foundation 34, and the third anchor foundation 35 are arranged at intervals in the left-right direction. First anchor holes, second anchor holes, and third anchor holes are provided on the mountain area. The first anchor foundation 33, the second anchor foundation 34, and the third anchor foundation 35 are respectively formed in the first anchor hole, the second anchor hole, and the third anchor hole. The upper ends of the first anchor foundation 33, the second anchor foundation 34, and the third anchor foundation 35 are connected to the bearing platform 1, and the heights of the first anchor foundation 33, the second anchor foundation 34, and the third anchor foundation 35 decrease in sequence. Thus, the first anchor foundation 33, the second anchor foundation 34, and the third anchor foundation 35 can better adapt to the natural slope of the terrain, reduce excessive interference with the ground surface, and at the same time ensure that each level of foundation can be firmly anchored in its respective geological layer, improving the stability of the overall structure.

[0039] In some embodiments, the anchor foundation 3 further includes a plurality of flanges 36. The plurality of flanges 36 are provided on the outer peripheral surface of the second base 32 and are arranged at intervals in the up-down direction. Specifically, as Figure 1 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 anchor rod is inserted into the first part and the second part, concrete is poured into the first part and the second part. The flange 36 is a variable-diameter part and is formed in the first part, and the second base 32 is formed in the second part. Thus, the anti-pulling and compressive bearing capacities of the anchor foundation 3 of the anchor foundation 3 are improved through the flange 36.

[0040] In some embodiments, the anchor foundation 3 further includes a plurality of positioning members 37. The plurality of positioning members 37 are all inserted through the first anchor bar 31 at intervals in the up-down direction and are located in the anchor hole. The outer peripheral surface of the positioning member 37 abuts against the inner peripheral surface of the anchor hole so as to position the first anchor bar 31 by the positioning member 37. Specifically, as Figure 1 、 Figure 4 and Figure 5As shown, the positioning member 37 is an arc-shaped smooth round positioning rib. The positioning member 37 is sleeved on the first anchor bar 31 and is arranged in the anchor hole. The outer peripheral surface of the positioning member 37 abuts against the inner peripheral surface of the anchor hole. Thus, the positioning member 37 positions the first anchor bar 31, ensuring that the position of the first anchor bar 31 does not deviate during the concrete pouring process, ensuring that the anchor rod remains vertical or at a predetermined angle during the installation process, and avoiding uneven stress or structural safety hazards caused by installation deviation. In addition, there may be two positioning steel bars (such as Figure 1 shown). One positioning steel bar is arranged adjacent to the upper end of the first anchor bar 31, and the other positioning steel bar is arranged adjacent to the lower end of the first anchor bar 31. Thus, by arranging positioning steel bars at different heights of the first anchor bar 31, not only can it ensure that the first anchor bar 31 remains vertical during concrete pouring, avoiding deflection, thereby improving the vertical bearing capacity and stability of the entire foundation structure, but also it can better disperse the load applied to the first anchor bar 31, avoid local stress concentration, reduce the bending risk of the first anchor bar 31 during the stress process, and enhance its tensile and shear resistance performance.

[0041] In some embodiments, the anchor rod foundation 3 further includes a plurality of second anchor bars 38. The plurality of second anchor bars 38 are all welded to the upper end of the first anchor bar 31. The plurality of second anchor bars 38 are arranged at intervals along the circumferential direction of the first anchor bar 31. The plurality of second anchor bars 38 are arranged in the steel bar cage 11 of the bearing platform 1. Specifically, as Figure 2 and Figure 3 shown, the plurality of second anchor bars 38 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 38 extend into the steel bar cage 11 and are welded to the steel bar cage 11. Thus, the overall connection strength between the bearing platform 1 and the foundation is enhanced by the plurality of second anchor bars 38, 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 interval arrangement of the plurality of second anchor bars 38 is also beneficial to the full perfusion of concrete, ensuring the close combination between the concrete and the anchor rod, and improving the durability of the anchoring area.

[0042] 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, the anchoring ability of the anchor rod assembly in the deep underground can be significantly enhanced by the plurality of first anchor bars 31, the load of the upper structure can be effectively transmitted and dispersed, and the stability of the anchor rod assembly is improved.

[0043] In some embodiments, the steel reinforcement cage 11 includes a first main reinforcement bar 111, a second main reinforcement bar 112, erection reinforcement bars 113, and web reinforcement bars 114. The first main reinforcement bar 111 and the second main reinforcement bar 112 are arranged at intervals in the up-down direction. The erection reinforcement bars 113 are all arranged between the first main reinforcement bar 111 and the second main reinforcement bar 112 and are respectively connected to the first main reinforcement bar 111 and the second main reinforcement bar 112. The web reinforcement bars 114 are arranged between the first main reinforcement bar 111 and the second main reinforcement bar 112 and are connected to the erection reinforcement bars 113. Specifically, as Figure 1 shown, the first main reinforcement bar 111 and the second main reinforcement bar 112 are alternately arranged along the vertical direction (up-down direction) of the bearing platform 1. Such a layout can effectively disperse the vertical loads borne by the bearing platform 1, such as the weight of the upper structure and the reaction force from the ground. The interval setting 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 bonding performance between the steel bars and the concrete. Through the coordinated work of each part of the steel bars in the steel reinforcement cage 11 of the bearing platform 1, a strong system that can resist both vertical loads and effectively cope with horizontal loads is formed. The first main reinforcement bar 111 and the second main reinforcement bar 112 are responsible for bearing the vertical forces, while the erection reinforcement bars 113 and the web reinforcement bars 114 strengthen the resistance of the structure in the horizontal and shear directions. The combination of the four improves the bearing capacity of the bearing platform 1 for complex loads and ensures the long-term safety and durability of the structure.

[0044] In some embodiments, the embedded steel pipes 2 include a first embedded steel pipe 21 and a second embedded steel pipe 22. The first embedded steel pipe 21 and the second embedded steel pipe 22 are both arranged on the bearing platform 1 and are arranged opposite to each other at intervals along the length direction of the bearing platform 1. Specifically, as Figure 1 and Figure 6 shown, the number of the embedded steel pipes 2 can be two, namely the first embedded steel pipe 21 and the second embedded steel pipe 22. The first embedded steel pipe 21 and the second embedded steel pipe 22 are arranged at intervals in the left-right direction on the bearing platform 1, and the heights of the first embedded steel pipe 21 and the second embedded steel pipe 22 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 embedded steel pipe 2 is provided with a plurality of through holes 23 that penetrate the radial direction of the embedded steel pipe 2 along the radial direction of the embedded steel pipe 2. The plurality of through holes 23 are arranged in multiple rows at intervals along the extending direction of the embedded steel pipe 2, and each row includes several through holes 23 that are arranged at intervals along the circumferential direction of the embedded steel pipe 2. The through holes 23 are suitable for installing anchor bolts 24. Specifically, as Figure 1As shown in the figure, a plurality of through holes 23 penetrating the embedded steel pipe 2 in the inner and outer directions are provided at the upper end of the embedded steel pipe 2. The plurality of through holes 23 are arranged in multiple rows at intervals in the up and down directions. Each row includes several through holes 23 arranged at intervals in the circumferential direction of the embedded steel pipe 2. When the photovoltaic support is inserted into the upper end of the embedded steel pipe 2, the photovoltaic support and the embedded steel pipe 2 are fixed together through the anchor bolts 24. Thus, the connection ability between the embedded steel pipe 2 and the photovoltaic support is enhanced, ensuring the stability and safety of the structure of the embedded steel pipe 2 and the photovoltaic support.

[0046] The mountain anchor foundation 100 according to the embodiment of the present invention is mainly used for the foundation tower positions in photovoltaic power stations with a certain thickness of soil layer on the upper part and weathered rock on the lower part. It can be applied to various terrains such as flat land, hills, and mountains, but the advantages in mountainous areas are greater. The cap 1 and the anchor part of the foundation are both made of cast-in-place reinforced concrete components. At the same time, steel pipes 2 or steel sections are directly embedded in the cap 1. Finally, the embedded steel pipes or steel sections are connected to the upper support structure through bolts.

[0047] The mountain anchor foundation 100 of the embodiment of the present invention can be used for the construction of the support foundation of a mountain photovoltaic power station; or for the foundation with a thin upper covering layer and weathered rock on the lower part; or for the construction of the support foundation of a photovoltaic power station with high requirements for environmental protection of water and soil and high requirements for construction period.

[0048] Specifically, the mountain anchor foundation 100 of the embodiment of the present invention is mainly used for the foundation tower positions in photovoltaic power stations with a certain thickness of soil layer on the upper part and weathered rock on the lower part. It can be applied to various terrains such as flat land, hills, and mountains, but the advantages in mountainous areas are greater. For a photovoltaic power station located in a mountainous area, the geological conditions generally have a thin soil layer on the upper part and weathered rock on the lower part, or are basically in a state of exposed bedrock. The terrain conditions generally have a relatively 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, thereby reducing the construction risk. Canceling the setting of the main column can save the construction period (omitting processes such as steel bar binding, formwork support, pouring, and curing of the main column); from the perspective of environmental protection of water and soil, minimizing the damage to the surrounding environment and reducing soil erosion, it is necessary to consider the original soil foundation. At the same time, the inclination of the cap minimizes the excavation of foundation pit soil, reducing the damage to environmental protection of water and soil; from the perspective of economic benefits, making full use of the characteristics of the rock or the original soil itself to reduce the foundation engineering quantity, and at the same time canceling the concrete main column can achieve a large-scale optimization of the engineering quantity; from the perspective of adapting to the terrain and light, the coordination with the terrain and light angle can be achieved by setting the inclination of the cap and the combination of the height of the embedded parts. In this way, a mountain anchor foundation can comprehensively cover the above-mentioned existing problems or difficulties, realizing all the benefits of safety, economy, and environmental protection.

[0049] The mountain anchor foundation 100 according to the embodiment of the utility model can make full use of the mechanical properties of the rock itself and thus reduce the amount of material of the foundation itself; it can fully realize mechanized construction, because the "miniaturization" and "lightweight" of the construction equipment can greatly improve the construction efficiency and reduce the construction risk when constructing in mountainous areas; the size of the cap 1 is small, which also effectively reduces the excavation area of ​​the rock / soil body; the middle and bottom of each anchor are spaced apart with an "enlarged head", which can increase the overall pull-out bearing capacity of the anchor and the foundation, and has a significant effect on reducing the amount of foundation materials; by tilting the cap 1, it can fully adapt to various terrains, and at the same time, the light angle can be adjusted in combination with the high and low steel structures pre-buried in the cap 1; the cancellation of the main column of the foundation significantly reduces the amount of foundation materials, and at the same time reduces the construction period and improves the construction efficiency; the cancellation of the main column and the tilted arrangement of the superimposed cap 1 can minimize the excavation of the foundation pit, and minimize the damage to the impact on environmental water conservation. In this way, the investment cost of the project can be significantly reduced, and it is also beneficial to soil and water conservation and environmental protection.
