Abstract
Description
Technical Field
[0001] This disclosure relates to the field of offshore photovoltaic equipment technology, and more specifically, to a pile arrangement structure for an offshore photovoltaic test pile area. Background Technology
[0002] Among renewable energy sources, solar photovoltaic power generation is a hot topic in renewable energy utilization. Offshore photovoltaic construction will use a large number of pile foundation structures. Fixed pile foundation structures are fixed at one end in the sea and extend to the sea level at the other end, thus serving as the foundation for subsequent fixed construction. The design of the structural parameters of the pile foundation not only determines the fixing capacity of the pile foundation, but also affects the overall cost.
[0003] For offshore photovoltaic projects, the grid structure needs to be reliably fixed on the pile foundation to provide a supporting foundation for the subsequent installation of photovoltaic modules. Before a large number of pile foundations in offshore photovoltaic projects are laid on the sea surface, it is necessary to conduct pile testing to verify the reliability of the pile foundation structure. Therefore, how to reasonably and effectively arrange the pile testing area is one of the key tasks in the basic construction of offshore photovoltaic projects.

[0029] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description
[0030] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this disclosure and, together with the description, serve to explain the principles of this disclosure. It is obvious that the drawings described below are merely some embodiments of this disclosure, and those skilled in the art can obtain other drawings based on these drawings without any inventive effort.

[0034] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.
[0035] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.
[0036] In related technologies, offshore photovoltaic projects face complex geological conditions (such as silt, sand, and rock), and preliminary geological survey data may contain errors. If large-scale pile installation is undertaken hastily, it may lead to unreasonable pile foundation design later, affecting the normal operation of the photovoltaic structure. Therefore, test pile operations are necessary before large-scale pile installation. Test piles can verify parameters such as soil layer distribution, bearing capacity, and friction coefficient, ensuring the reliability of the design basis. However, optimizing the pile layout in the test pile area is a challenge and a key task in offshore photovoltaic projects.
[0037] Based on this, see Figure 1 This disclosure provides a pile arrangement structure for a marine photovoltaic test pile area, which includes a first pile area 1, a second pile area 2, and a third pile area 3. The test pile area has a first direction 5 and a second direction 6, which intersect. Within the test pile area, along the first direction 5, the first pile area 1, the second pile area 2, the third pile area 3, the second pile area 2, and the first pile area 1 are arranged sequentially. The first pile area 1 is used to provide a stable foundation for the second pile area 2 and the third pile area 3. The second pile area 2 is used to provide reaction support for the third pile area 3. The third pile area 3 is used to provide a basis for the subsequent pile design and arrangement in the test pile area.
[0038] It is understood that in this embodiment, the test pile area can be set as a rectangle, with the first direction 5 being the width direction of the rectangle and the second direction 6 being the length direction of the rectangle. It should also be noted that in other embodiments, the test pile area can be of other shapes, which will not be elaborated upon in this application.
[0039] It should be noted that in some embodiments, the test pile area may have multiple identical repeating units, but this disclosure only describes one repeating unit.
[0040] In some embodiments of this disclosure, see Figure 1The first pile area 1 includes a plurality of foundation piles 11 evenly arranged along the second direction 6; wherein the spacing between adjacent foundation piles 11 is between 14000 and 15000 mm. For example, the spacing between adjacent foundation piles 11 can be 14000 mm, 14400 mm, 14800 mm, or 15000 mm, etc.
[0041] It should be noted that the spacing between adjacent foundation piles 11 as described in this disclosure refers to the distance between the centers of adjacent foundation piles 11.
[0042] In some embodiments of this disclosure, the number of foundation piles 11 in the test pile area is between 3 and 5. For example, the number of foundation piles 11 can be 3, 4, or 5. It should be noted that in other embodiments, the number of foundation piles 11 is not limited to these. It should also be noted that the number of foundation piles 11 here refers to the number of foundation piles 11 in the entire test pile area.
[0043] As an example, the number of foundation piles 11 is set to 4. It can be understood that in this embodiment of the disclosure, the first pile area 1, the second pile area 2, the third pile area 3, the second pile area 2 and the first pile area 1 are arranged along the first direction 5. That is to say, the number of foundation piles 11 in the two first pile areas 1 can be set to 2 each. This arrangement can provide a more stable foundation for the second pile area 2 and the second pile area 2.
[0044] As another example, the first pile area 1 includes a plurality of foundation piles 11 evenly arranged along the second direction 6; wherein the spacing between adjacent foundation piles 11 is between 14,000 and 15,000 mm; and the number of foundation piles 11 in the test pile area is between 3 and 5.
[0045] In some embodiments of this disclosure, see Figure 1 The second pile area 2 includes a plurality of anchor piles 21 evenly arranged along the second direction 6; wherein the spacing between adjacent anchor piles 21 is between 6120 and 8280 mm. For example, the spacing between adjacent anchor piles 21 can be 6120 mm, 6620 mm, 7200 mm, or 8280 mm, etc.
[0046] It should be noted that the spacing between adjacent anchor piles 21 as described in this disclosure refers to the distance between the centers of adjacent anchor piles 21.
[0047] In some embodiments of this disclosure, the number of anchor piles 21 in the test pile area is between 7 and 9. For example, the number of anchor piles 21 can be 7, 8, or 9. It should be noted that in other embodiments, the number of anchor piles 21 is not limited to these. It should also be noted that the number of anchor piles 21 here refers to the number of anchor piles 21 in the entire test pile area.
[0048] As an example, the number of anchor piles 21 is set to 8. It can be understood that in the embodiment of this disclosure, the first pile area 1, the second pile area 2, the third pile area 3, the second pile area 2 and the first pile area 1 are arranged along the first direction 5. That is to say, the number of foundation piles 11 in the two second pile areas 2 can be set to 4 each. This arrangement allows the anchor piles 21 to better provide counter-support force to the third pile area 3, thereby improving the accuracy and reliability of the test pile.
[0049] As another example, the second pile area 2 includes a plurality of anchor piles 21 evenly arranged along the second direction 6; wherein the spacing between adjacent anchor piles 21 is between 6120 and 8280 mm; and the number of anchor piles 21 in the test pile area is between 7 and 9.
[0050] In some embodiments of this disclosure, see Figure 1 The third pile area 3 includes a plurality of test piles 31 evenly arranged along the second direction 6; wherein the spacing between adjacent test piles 31 is between 6120 and 8280 mm. For example, the spacing between adjacent test piles 31 can be 6120 mm, 6620 mm, 7200 mm or 8280 mm.
[0051] It should be noted that the spacing between adjacent test piles 31 as described in this disclosure refers to the distance between the centers of adjacent test piles.
[0052] In some embodiments of this disclosure, the number of test piles 31 is between 2 and 4. For example, the number of test piles 31 can be 2, 3, or 4. It should be noted that in other embodiments, the number of test piles 31 is not limited to this.
[0053] As an example, the third pile area 3 includes a plurality of test piles 31 uniformly arranged along the second direction 6; wherein the spacing between adjacent test piles 31 is between 6120 and 8280 mm; and the number of test piles 31 is between 2 and 4.
[0054] In some embodiments of this disclosure, see Figure 1 Multiple test piles 31 are located on the axis of symmetry of the test pile area along the second direction 6. It is understood that, as described above, in this embodiment of the present disclosure, the test pile area can be rectangular, and the axis of symmetry along the second direction 6 refers to the longer axis of symmetry of the test pile area.
[0055] It is understood that, in other embodiments, the axis of symmetry along the second direction 6 can be determined according to the shape of the test pile area, which will not be elaborated in this application.
[0056] Furthermore, as an example, multiple test piles 31 are located on the same horizontal line. This arrangement can further improve the reliability and accuracy of the test piles.
[0057] In some embodiments of this disclosure, see Figure 1 The arrangement structure includes multiple pile groups 4 arranged in an array along the second direction 6; some test piles 31 are located between adjacent pile groups 4.
[0058] As an example, a test pile 31 can be set between adjacent pile groups 4.
[0059] Furthermore, the test pile 31 set between adjacent pile groups 4 can be located at the center between adjacent pile groups 4. This setting can improve the accuracy and reliability of the test pile 31 while ensuring better support for the test pile 31 by the foundation pile 11 and anchor pile 21.
[0060] In this embodiment, the pile group 4 includes a subgroup 41, a foundation pile 11, and a test pile 31 symmetrically arranged along the first direction 5; wherein the foundation pile 11 and the test pile 31 are located between adjacent subgroups 41.
[0061] As an example, subgroup 41 includes anchor piles 21 arranged symmetrically along the second direction 6.
[0062] That is to say, a pile group 4 includes 4 anchor piles 21, 1 test pile 31 and 2 foundation piles 11.
[0063] The following is a detailed description of the arrangement of pile group 4.
[0064] See Figure 1 Four anchor piles 21 are set, including the first anchor pile 211, the second anchor pile 212, the third anchor pile 213 and the fourth anchor pile 214; two foundation piles 11 are set as the first foundation pile 111 and the second foundation pile 112.
[0065] The first anchor pile 211 and the second anchor pile 212 are symmetrically arranged about the first direction 5 of the test pile area, and the first foundation pile 111 is located on the line of symmetry between the first anchor pile 211 and the second anchor pile 212. Similarly, the third anchor pile 213 and the fourth anchor pile 214 are symmetrically arranged about the first direction 5 of the test pile area, and the second foundation pile 112 is located on the line of symmetry between the third anchor pile 213 and the fourth anchor pile 214.
[0066] Furthermore, the first anchor pile 211 and the third anchor pile 213 are located on the same horizontal line, as are the second anchor pile 212 and the second anchor pile 213. Naturally, the first foundation pile 111 and the second foundation pile 112 are also located on the same horizontal line.
[0067] In some embodiments of this disclosure, within the same pile group 4, the foundation pile 11 and the test pile 31 are located on the same horizontal line. Specifically, within the same pile group 4, the first foundation pile 111, the second foundation pile 112, and the test pile 31 are located on the same horizontal line.
[0068] In some embodiments of this invention, within the same pile group 4, along the first direction 5, the ratio of the distance between the foundation pile 11 and the anchor pile 21 to the distance between the anchor pile 21 and the test pile 31 is between 0.36 and 0.48.
[0069] For example, along the first direction 5, the ratio of the distance between the first foundation pile 111 and the first anchor pile 211 (or the second anchor pile 212) to the distance between the first anchor pile 211 and the test pile 31 can be 0.36, 0.42, or 0.48. It should be noted that in other embodiments, the ratio of the distance between the first foundation pile 111 and the first anchor pile 211 (or the second anchor pile 212) to the distance between the first anchor pile 211 and the test pile 31 is not limited to this, and will not be elaborated upon in this application.
[0070] As an example, along the first direction 5, the distance between the first foundation pile 111 and the first anchor pile 211 can be 1500mm; the distance between the first anchor pile 211 and the test pile 31 can be 3600mm.
