Description

Technical Field

[0001] This utility model relates to the field of wind power, specifically to a tower foundation and a wind turbine tower. Background Technology

[0002] The tower foundation is the bottom structure of the wind turbine tower, serving to support and anchor the tower to the ground, ensuring the safe and stable operation of the wind turbine. In related technologies, a tower foundation includes a foundation cylinder, a top plate, and supporting components. The foundation cylinder supports the wind turbine tower, the top plate is located at the top of the foundation cylinder, and the supporting components, which are inclined bent frames or ribs, are placed around the outer perimeter of the foundation cylinder to support it. The supporting components need to be connected to the foundation cylinder through the top plate to ensure effective support. However, the structure of the supporting components connecting to the foundation cylinder through the top plate is relatively complex, resulting in a complex tower foundation structure with many components, which is inconvenient for tower foundation installation and component transportation.

Detailed Implementation

[0035] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0036] The following is for reference. Figures 1-11 This invention describes the tower foundation and wind turbine tower provided in the embodiments of the present invention.

[0037] like Figures 1-11 As shown, the tower foundation provided in this embodiment of the present invention includes a foundation cylinder 3 and side support members 4.

[0038] The side support 4 is located on the outer side of the peripheral wall of the foundation cylinder 3 and has a connecting end that connects to the foundation cylinder 3. The side support 4 is used to support the foundation cylinder 3 from the outer side of the peripheral wall of the foundation cylinder 3. The foundation cylinder 3 includes a post-cast strip 32 and multiple cylindrical plates 31. The multiple cylindrical plates 31 are arranged sequentially along a circumference. Adjacent cylindrical plates 31 are connected by the post-cast strip 32. The connecting end of the side support 4 is connected to the adjacent two cylindrical plates 31 through the post-cast strip 32.

[0039] like Figure 5 and Figure 7 As shown, optionally, the foundation cylinder 3 can be a hollow cylinder, and the circumference of the foundation cylinder 3 can be parallel to the vertical direction. The foundation cylinder 3 can be used to support the wind turbine tower, and the top of the wind turbine tower can be used to assemble a wind turbine generator for wind power generation. Side supports 4 can be, but are not limited to, multiple supports 4. Multiple side supports 4 are located on the outer side of the peripheral wall of the foundation cylinder 3 and are arranged at intervals along the circumference of the foundation cylinder 3. The side supports 4 can extend vertically and be arranged radially inclined along the foundation cylinder 3. The top end of the side support 4 is closer to the foundation cylinder 3 horizontally than its bottom end. The top end of the side support 4 can serve as the connecting end for connecting the side support 4 to the foundation cylinder 3.

[0040] The basic cylinder 3 includes a post-cast strip 32 and multiple cylindrical sections 31. The multiple cylindrical sections 31 are arranged sequentially along a circumference. The post-cast strip 32 is cast between two adjacent cylindrical sections 31 to connect the two adjacent cylindrical sections 31.

[0041] The top of the side support 4 is cast and connected to the post-cast strip 32 of the cylinder, thereby connecting it to two adjacent cylinder sections 31 through the post-cast strip 32. This ensures the reliability and stability of the connection between the side support 4 and the foundation cylinder 3, enabling the side support 4 to support the foundation cylinder 3.

[0042] During the transportation and installation of the tower foundation, the side support member 4, being a simple rod structure, is easy to transport and place. The foundation cylinder 3 is mainly transported by multiple cylindrical sections 31, thus facilitating its transportation and placement. Connecting adjacent cylindrical sections 31 via the post-cast strip 32 ensures high connection stability and reliability, guaranteeing the structural strength of the foundation cylinder 3.

[0043] In this embodiment of the tower foundation, the connecting end of the side support member 4 is connected to the two adjacent cylindrical sections 31 via a post-cast strip 32 for connecting the two adjacent sections 31. This allows the side support member 4 to be directly connected to the foundation cylinder 3 through its connecting end. Compared with related technologies, the side support member 4 no longer needs to be connected to the foundation cylinder 3 via a top plate, eliminating the need for a top plate and the connection process between the side support member 4 and the top plate. Furthermore, the connection between the two adjacent cylindrical sections 31 and the connection between the side support member 4 and the foundation cylinder 3 can be achieved simultaneously through the post-cast strip 32, thereby enabling a stable and reliable connection between the side support member 4 and the foundation cylinder 3. This allows the side support member 4 to stably and reliably support the foundation cylinder 3, simplifies the connection structure between the side support member 4 and the foundation cylinder 3, reduces the connection difficulty, reduces the types of tower foundation components, and the simpler structure of the side support member 4 facilitates the installation, construction, and transportation of the tower foundation components.

[0044] In practical applications, multiple side support members 4 and multiple post-cast strips 32 can be connected in a one-to-one correspondence, but are not limited to one-to-one correspondence.

[0045] In one embodiment of the present invention, the base cylinder 3 may further include a post-gating gate 33 and a post-gating channel 34. The post-gating gate 33 and the post-gating channel 34 may be disposed between two adjacent cylinder plates 31 and communicate with each other. The post-gating gate 33 may be disposed at the top of at least a portion of the post-gating channel 34. The cylinder post-gating strip 32 may be formed in the post-gating gate 33 and the post-gating channel 34. The connecting end of the side support 4 may be connected to the portion of the cylinder post-gating strip 32 formed in the post-gating gate 33.

[0046] like Figures 1-5 as well as Figures 9-11 As shown, optionally, a post-gating gate 33 and a post-gating channel 34 can be provided between two adjacent cylindrical sections 31. The post-gating gate 33 and the post-gating channel 34 can be respectively provided and connected in a direction parallel to the axial direction of the foundation cylinder 3. Along the radial direction of the foundation cylinder 3, the size of the post-gating gate 33 can be, but is not limited to, larger than the size of the post-gating channel 34. The post-gating gate 33 can be, but is not limited to, located at the top of the outer part of the post-gating channel 34 along the radial direction of the foundation cylinder 3. The casting medium can be poured in through the post-gating gate 33, and then flow downward through the post-gating gate 33 into the post-gating channel 34, and continue to flow downward along the post-gating channel 34, finally filling the post-gating gate 33 and the post-gating channel 34, so as to form a post-gating strip 32 in the post-gating gate 33 and the post-gating channel 34, thereby stably and reliably connecting the two adjacent cylindrical sections 31 and ensuring the structural strength of the foundation cylinder 3. The post-gate 33 may form an opening on the outer peripheral wall of at least two adjacent cylindrical plates 31, so that the top end of the side support 4 can extend into the post-gate 33 between the two adjacent cylindrical plates 31 through the opening. The post-gate 33 may, but is not limited to, penetrate the two adjacent cylindrical plates 31 radially.

[0047] The top of the side support 4 can be connected to the portion of the post-cast strip 32 formed in the post-cast gate 33. In other words, the top of the side support 4 can be located in the post-cast gate 33. After the post-cast strip 32 is formed by casting in the post-cast gate 33 and the post-cast channel 34, the top of the side support 4 is cast and connected by the post-cast strip 32, thereby ensuring the stability and reliability of the connection between the side support 4 and the foundation cylinder 3. Furthermore, the connection between two adjacent cylinder plates 31 and the connection between the side support 4 and the foundation cylinder 3 can be achieved simultaneously through the post-cast strip 32.

[0048] By setting the post-gating gate 33, it is convenient to pour the casting medium to form the post-gating strip 32 of the cylinder. It is also convenient for the top of the side support 4 to extend into the post-gating gate 33 between two adjacent cylinders 31 so that it can be cast and connected by the post-gating strip 32 of the cylinder.

[0049] In practical applications, the post-gate 33 may be located, but is not limited to, at the top of the outer portion of the post-gate runner 34.

[0050] In one embodiment of this utility model, the post-gating gate 33 can be located at the top of the post-gating channel 34.

[0051] This design facilitates the setting of the post-gate 33 and the post-gate runner 34.

[0052] In one embodiment of this utility model, in the circumferential direction of the base cylinder 3, the cylinder plate 31 may have two sidewalls, and the sidewalls may be provided with multiple flow channel protrusions 312. The flow channel protrusions 312 may extend in a portion of the sidewall parallel to the axial direction of the base cylinder 3 and protrude toward adjacent cylinder plates 31. The multiple flow channel protrusions 312 may be arranged at intervals in the radial direction of the base cylinder 3, and the gap between two adjacent flow channel protrusions 312 may form a flow channel groove 313. The portions of two adjacent sidewalls of two adjacent cylinder plates 31 that are not provided with flow channel protrusions 312 may jointly form a post-gating gate 33. Both sidewalls of the cylindrical plate 31 may be provided with flow channel grooves 313. The two adjacent flow channel grooves 313 of two adjacent cylindrical plates 31 may be connected to form a post-cast flow channel 34. Alternatively, one sidewall of the two sidewalls of the cylindrical plate 31 may be provided with a flow channel groove 313. The flow channel groove 313 of one cylindrical plate 31 may be connected with the sidewall of the other cylindrical plate 31 to form a post-cast flow channel 34.

[0053] like Figures 9-11 As shown, optionally, the circumferential sidewall of the cylinder 31 is provided with two flow channel protrusions 312, which may be strips extending in the vertical direction. The two flow channel protrusions 312 may be arranged at a radial interval along the cylinder 31 so that a flow channel groove 313 extending in the vertical direction is formed between the two cylinder flow channel protrusions 312.

[0054] The circumferential sidewall of the tube 31 may also have a portion without the runner flange 312. This portion may be located above the two runner flanges 312 and serve as a gating space 311 for forming the post-gating gate 33. The gating space 311 may communicate with the runner groove 313 between the two runner flanges 312 and be located above the runner groove 313. In this case, the post-gating gate 33 may be located at the top of the entire post-gating runner 34.

[0055] The cylindrical plate 31 may have a first side wall and a second side wall, both of which are provided with a gating space 311, a runner flange 312, and a runner groove 313. In two adjacent cylindrical plates 31, the first side wall of one cylindrical plate 31 and the second side wall of the other cylindrical plate 31 may be arranged opposite each other along the circumference of the base cylinder 3. The gating spaces 311 on the opposite first side wall and the gating spaces 311 on the opposite second side wall may be arranged side by side and connected along the circumference of the base cylinder 3 to form a post-gating gate 33. The runner flanges 312 on the opposite first side wall and the runner flanges 312 on the opposite second side wall may abut one-to-one, so that the runner grooves 313 on the opposite first side wall and the runner grooves 313 on the opposite second side wall may be arranged side by side and connected along the circumference of the base cylinder 3 to form a post-gating runner 34.

[0056] The first and second sidewalls are provided with multiple flow channel protrusions 312 and flow channel grooves 313, so that the flow channel grooves 313 on the first and second sidewalls form a casting channel 34, which can increase the circumferential dimension of the casting channel 34 in the foundation cylinder 3, thereby improving the connection strength and connection stability of adjacent cylinder plates 31, and thus improving the structural strength of the foundation cylinder 3.

[0057] The top of the side support 4 can be located at the opening formed by the post-gating gate 33 on the outer peripheral wall of two adjacent cylindrical sections 31. Optionally, the width of the side support 4 can be the same as the width of the opening so that it can serve as a partial casting template at the post-gating gate 33 when the post-gating strip 32 is cast.

[0058] In practical applications, the post-cast runner 34 may be formed by connecting the runner groove 313 on the first side wall and the runner groove 313 on the second side wall, which are arranged opposite to each other.

[0059] In another embodiment of this utility model, on the first and second sidewalls arranged opposite to each other, the first sidewall is provided with a plurality of flow channel protrusions 312 spaced radially in the base cylinder 3, while the second sidewall is not provided with flow channel protrusions 312. The plurality of flow channel protrusions 312 on the first sidewall abut against the second sidewall, so that the flow channel grooves 313 on the first sidewall and the second sidewall together form the post-cast flow channel 34. In other words, one of the first and second sidewalls is provided with a plurality of flow channel protrusions 312 and forms a flow channel groove 313, which forms the post-cast flow channel 34. Therefore, the cylinder 31 only needs to have flow channel protrusions 312 on one of its sidewalls to form the flow channel groove 313, which facilitates the prefabrication of the cylinder 31.

[0060] In another embodiment of this utility model, on the first side wall and the second side wall that are arranged opposite to each other, the flow channel protrusion 312 on the first side wall and the flow channel protrusion 312 on the second side wall are spaced apart in the radial direction of the base cylinder 3. The flow channel protrusion 312 on the first side wall abuts against the second side wall, and the flow channel protrusion 312 on the second side wall abuts against the first side wall, so that the flow channel groove 313 on the first side wall and the flow channel groove 313 on the second side wall respectively form the post-cast flow channel 34. The gap between the flow channel protrusion 312 on the first side wall and the flow channel protrusion 312 on the second side wall in the radial direction of the base cylinder 3 can also form the post-cast flow channel 34. In this configuration, a flow channel protrusion 312 can be provided on both the first and second sidewalls. The flow channel protrusions 312 on the first and second sidewalls are staggered to form flow channel grooves 313. These flow channel grooves 313 form post-cast flow channels 34, so that only one flow channel protrusion 312 needs to be prefabricated on each sidewall of the cylindrical section 31, which can improve the prefabrication quality of the flow channel protrusions 312. In this configuration, multiple flow channel protrusions 312 can also be provided on both the first and second sidewalls to increase the number of flow channel protrusions 312 between adjacent cylindrical sections 31, thereby increasing the contact area between the casting medium and the cylindrical section 31, improving the connection strength and stability of adjacent cylindrical sections 31, and thus improving the structural strength of the foundation cylinder 3.

[0061] In one embodiment of the present invention, the surface of one of the multiple flow channel protrusions 312 on the side wall facing the inner space of the base cylinder 3 can be flush with the inner peripheral wall of the base cylinder 3, and the surface of the other flow channel protrusion 312 facing the outer space of the base cylinder 3 can be flush with the outer peripheral wall of the base cylinder 3.

[0062] like Figures 9-11As shown, optionally, in the two flow channel protrusions 312 on the same side wall of the cylindrical plate 31, along the radial direction of the cylindrical plate 31, the inner wall of the inner flow channel protrusion 312 can be flush with the inner peripheral wall of the cylindrical plate 31, and the outer wall of the outer flow channel protrusion 312 can be flush with the outer peripheral wall of the cylindrical plate 31, so that the flow channel protrusions 312 of the two adjacent cylindrical plates 31 can abut one-to-one. On the basis of making the inner and outer peripheral walls of the base cylinder 3 smooth and continuous surfaces, the distance between the two adjacent flow channel protrusions 312 in the radial direction of the base cylinder 3 can be increased as much as possible, so as to increase the size of the post-cast flow channel 34 in the radial direction of the base cylinder 3 as much as possible, thereby increasing the size of the post-cast strip 32 in the radial direction of the base cylinder 3, and thus improving the connection strength and connection stability between the two adjacent cylindrical plates and the side support and the base cylinder.

[0063] In one embodiment of this utility model, the portion of the side wall without the flow channel flange 312 may be provided with a plurality of first cylindrical ribs 35, and the portion of the side wall with the flow channel flange 312 may be provided with a plurality of second cylindrical ribs 36. The first cylindrical ribs 35 and the second cylindrical ribs 36 may both extend toward the adjacent cylindrical plate 31 relative to the side wall. The connecting end of the side support member 4 may be provided with a plurality of second end connecting ribs 42. The plurality of second end connecting ribs 42 may extend into the post-gating gate 33. The first cylindrical ribs 35, the second cylindrical ribs 36 and the second end connecting ribs 42 may all be cast in the post-gating strip 32 of the cylinder.

[0064] like Figure 2 , Figure 3 , Figure 5 as well as Figures 9-11 As shown, optionally, the side wall of the cylindrical plate 31 may be provided with a plurality of first cylindrical ribs 35 and a plurality of second cylindrical ribs 36. The plurality of first cylindrical ribs 35 may extend from the side wall of the cylindrical plate 31 into the gating space 311. The plurality of first cylindrical ribs 35 may be provided at intervals along the contour of the side wall of the cylindrical plate 31 along the gating space 311.

[0065] Multiple second cylindrical ribs 36 can extend from the side wall of the cylindrical plate 31 into the flow channel groove 313. The second cylindrical ribs 36 can be configured as two rows arranged at intervals along the radial direction of the base cylindrical body 3. Each row can include multiple second cylindrical ribs 36 arranged at intervals along the vertical direction and arranged at intervals from the upper end to the lower end of the flow channel groove 313.

[0066] The first cylindrical protruding rib 35 and the second cylindrical protruding rib 36 can both be used to be cast into the post-cast strip 32, thereby ensuring the stability and reliability of the connection between the post-cast strip 32 and the cylindrical plate 31.

[0067] Optionally, in two adjacent cylindrical sections 31, the first side wall of one cylindrical section 31 and the second side wall of the other cylindrical section 31 can be arranged opposite to each other along the circumference of the foundation cylinder 3. The first cylindrical ribs 35 on the opposite side wall and the first cylindrical ribs 35 on the opposite side wall are overlapped one-to-one, and the second cylindrical ribs 36 on the opposite side wall and the second cylindrical ribs 36 on the opposite side wall are overlapped one-to-one, thereby ensuring the stability and reliability of the connection between the two adjacent cylindrical sections 31 by the post-cast strip 32.

[0068] The top of the side support 4 can be located at the opening formed by the post-gating gate 33 on the outer peripheral wall of two adjacent cylindrical plates 31. The top of the side support 4 can be provided with multiple second end connecting ribs 42. The second end connecting ribs 42 can extend from the top surface of the side support 4 and extend into the corresponding post-gating gate 33. The second end connecting ribs 42 can extend along the extension direction of the side support 4, in other words, they can extend along the length direction of the side support 4. Multiple second end connecting ribs 42 can be provided at intervals along the outer peripheral contour of the top surface of the side support 4.

[0069] The second end connecting rib 42 can be used to be cast into the post-cast strip 32 of the cylinder, thereby ensuring the stability and reliability of the connection between the post-cast strip 32 of the cylinder and the side support 4.

[0070] In one embodiment of the present invention, some of the first cylindrical ribs 35 can be arranged radially at intervals along the base cylinder 3, and some of the second end connecting ribs 42 can be arranged circumferentially at intervals along the base cylinder 3 and extend radially along the base cylinder 3 for overlapping with some of the first cylindrical ribs 35 arranged radially at intervals along the base cylinder 3.

[0071] like Figure 2 , Figure 3 , Figure 8 and Figure 9 As shown, optionally, a plurality of first cylindrical ribs 35 may be arranged at intervals along the outline of the side wall of the cylindrical plate 31 in the gating space 311, wherein some of the first cylindrical ribs 35 may be located at the top of the gating space 311 and arranged at intervals along the radial direction of the base cylinder 3. In other words, some of the first cylindrical ribs 35 may be located at the top of the gating space 311 and arranged at intervals along the top surface of the cylindrical plate 31.

[0072] The top surface of the side support member 4 can be vertically arranged, and multiple second-end connecting ribs 42 can be spaced along the outer periphery of the top surface of the side support member 4. Some of the second-end connecting ribs 42 can be located at the upper end of the top surface of the side support member 4 and arranged at intervals along the circumference of the foundation cylinder 3. In other words, some of the second-end connecting ribs 42 can be located at the upper end of the top surface of the side support member 4 and arranged at intervals along the width direction of the side support member 4. In other words, some of the second-end connecting ribs 42 can be located at the upper end of the top surface of the side support member 4 and arranged at intervals along the top edge line of the top surface of the side support member 4. These second-end connecting ribs 42 extend along the length direction of the side support member 4, then bend and extend radially along the foundation cylinder 3 to overlap with the first cylinder protruding ribs 35 located at the top of the gating space 311 and arranged at intervals along the radial direction of the foundation cylinder 3 in the post-gating gate 33, and are cast into the cylinder post-gating strip 32, thereby ensuring the stability and reliability of the connection between the foundation cylinder 3 and the side support member 4.

[0073] Optionally, among the plurality of first cylindrical protrusions 35, another portion of the first cylindrical protrusions 35 may be arranged at intervals along the length direction of the side support 4 and overlap with the portion of the bent second end connecting rib 42 that extends along the length direction of the side support 4, so as to ensure the stability and reliability of the connection between the foundation cylinder 3 and the side support 4.

[0074] In one embodiment of the present invention, the cylindrical plate 31 may be provided with an anchoring boss 37. The anchoring boss 37 may protrude toward the inner space of the foundation cylindrical body 3 relative to the inner circumferential wall of the cylindrical plate 31.

[0075] like Figure 5 , Figure 7 and Figure 9 As shown, the top of the inner peripheral wall of the cylindrical plate 31 may be provided with an anchoring boss 37. The surface of the anchoring boss 37 along the circumferential direction of the cylindrical plate 31 may serve as part of the side wall surface of the cylindrical plate 31 and be used to form a partial gating space 311. A portion of the first cylindrical rib 35 may be provided on the surface of the anchoring boss 37 along the circumferential direction of the cylindrical plate 31 and extend into the gating space 311. In two adjacent cylindrical plates 31, the anchoring boss 37 of one cylindrical plate 31 may form a partial post-gating gate 33 with the anchoring boss 37 of the other cylindrical plate 31 and be used to cast the post-gating strip 32.

[0076] When the tower foundation is in use, the top of the foundation cylinder 3 can support the wind turbine tower cylinder, and the bottom section 6 of the tower cylinder can be located on the foundation cylinder 3. The top surface of the foundation cylinder 3 may, but is not limited to, have an annular groove, and the bottom section 6 of the tower cylinder can be embedded in the annular groove for restraint. The anchoring boss 37 can be used for anchoring connection with at least the bottom section 6 of the wind turbine tower cylinder.

[0077] The anchoring boss 37 can also increase the radial length of the post-gating gate 33 along the cylindrical section 31, so that the second end connecting rib 42 can extend into the post-gating gate 33, and increase the length of the second end connecting rib 42 that can extend into the post-gating gate 33, and increase the radial dimension of the part of the post-gating strip 32 in the post-gating gate 33 in the foundation cylinder 3, thereby ensuring the stability and reliability of the connection between the foundation cylinder 3 and the side support 4.

[0078] In practical applications, when pouring the post-pouring strip 32 of the cylinder, the bottom surface and inner peripheral wall of the anchoring boss 37 can be provided with a pouring template extending from the side wall of the cylinder 31 along the circumference of the cylinder 31, so as to prevent the pouring medium from overflowing from the post-pouring port 33.

[0079] In one embodiment of the present invention, the anchoring boss 37 may be provided with a plurality of anchor holes 38 extending vertically, and the plurality of anchor holes 38 may be arranged at intervals along the circumference of the foundation cylinder 3. The anchor holes 38 are used to insert anchors 5 for connecting the wind turbine tower cylinder.

[0080] like Figure 5 , Figure 7 and Figure 9 As shown, optionally, the anchoring boss 37 may be provided with a plurality of anchor holes 38 arranged at intervals along the circumference of the cylindrical plate 31. The anchor holes 38 penetrate the anchoring boss 37 in the vertical direction for inserting the anchor 5.

[0081] When the tower foundation is in use, the top of the foundation cylinder 3 can support the wind turbine tower cylinder. The bottom section 6 of the tower cylinder can be located on the foundation cylinder 3. The top surface of the foundation cylinder 3 may, but is not limited to, have an annular groove, and the bottom section 6 of the tower cylinder is embedded in the annular groove for restraint. The anchor 5 provided in the anchor hole 38 extends upward into the cylinder wall of the bottom section 6 of the tower cylinder to anchor the anchoring boss 37 and at least the bottom section 6 of the wind turbine tower cylinder.

[0082] Optionally, the tower foundation may also include a base plate 1, the foundation cylinder 3 may be located on the base plate 1, and the side support 4 may be connected between the post-cast strip 32 of the cylinder and the base plate 1.

[0083] like Figure 5 and Figure 7 As shown, optionally, the base plate 1 can be set horizontally, the foundation cylinder 3 can be set vertically on the base plate 1, the top of the side support 4 can be cast and connected to the post-cast strip 32 of the foundation cylinder 3, and the bottom of the side support 4 can be connected to the base plate 1 to support between the foundation cylinder 3 and the base plate 1 and bear tension and pressure, thereby reducing and dispersing the bending moment borne by the base plate 1, and being able to distribute and transfer the force on the foundation cylinder 3 to the base plate 1, so that the entire base plate 1 is evenly stressed, thereby ensuring the structural stability of the tower foundation.

[0084] Optionally, the bottom end of the side support 4 can be cast and connected to the base plate 1.

[0085] like Figure 5 and Figure 7 As shown, the base plate 1 may include a precast slab portion 11 and a post-cast slab portion 12. The precast slab portion 11 needs to be prefabricated in a prefabrication site such as a production workshop or manufacturing plant, and then transported to the installation site and placed in a designated position. The post-cast slab portion 12 can be cast on-site at a designated position in the installation site and is connected to the bottom end of the precast slab portion 11 and the side support member 4, thereby ensuring the reliability and stability of the connection between the side support member 4 and the base plate 1, while enabling the side support member 4 to distribute the bending moment of the base plate 1.

[0086] Optionally, the post-cast slab section 12 may include a post-cast strip 121 and a post-cast slab 122, and the precast slab section 11 may include a plurality of precast slabs 111. The plurality of precast slabs 111 may be arranged at intervals in a circumferential direction. Adjacent precast slabs 111 may be connected by the post-cast strip 121. The post-cast slab 122 may surround the post-cast strip 121 and the plurality of precast slabs 111 and be connected to the post-cast strip 121 and the plurality of precast slabs 111 respectively. The side support 4 may be connected to the bottom plate 1 through the post-cast slab 122.

[0087] like Figure 1 and Figure 5 As shown, optionally, but not limited to, multiple precast slabs 111 may be arranged at intervals in a circumferential direction. There may be a gap between two adjacent precast slabs 111 along the interval arrangement direction of the multiple precast slabs 111. The gap is used for casting post-cast strips 121. In other words, post-cast strips 121 are cast between adjacent precast slabs 111 to connect adjacent precast slabs 111.

[0088] The post-cast slab 122 may be annular, and may be selectively, but not limited to, circular. The post-cast slab 122 may surround the outer periphery of a plurality of precast slabs 111 connected by the post-cast strip 121, and may be connected to the post-cast strip 121 and the precast slabs 111 respectively.

[0089] During transportation, the base slab 1 mainly involves transporting multiple precast slabs 111, facilitating its transport and installation. The post-cast strip 121 connects adjacent precast slabs 111, ensuring high connection stability and reliability, thus guaranteeing the structural strength of the base slab 1. The post-cast slab 122 further secures the multiple precast slabs 111, further ensuring the structural strength of the base slab 1.

[0090] The bottom end of the side support 4 can be connected to the post-cast slab 122 in place to ensure the stability and reliability of the connection between the side support 4 and the base slab 1. At this time, the precast slab 111 can have a smaller volume, especially a smaller radial dimension, so as to facilitate transportation and construction and have a lower production cost.

[0091] Optionally, such as Figure 1 and Figure 7 As shown, the base plate 1 can be annular, and the internal space surrounding the base plate 1 can be located below the internal space of the foundation cylinder 3 and connected to the internal space of the foundation cylinder 3. The precast slab 111 can be fan-shaped to reduce the amount of material used in the base plate 1, thereby reducing the production cost, while reducing the volume and weight of the precast slab 111 to facilitate transportation and installation.

[0092] Optionally, such as Figure 1 and Figure 5 As shown, the post-cast slab 122 can be annular, and is optional but not limited to being circular. The post-cast slab 122 can surround the outer periphery of multiple precast slabs 111 connected by the post-cast strip 121, and is connected to the post-cast strip 121 and the precast slabs 111 respectively, so as to form a fastening effect on the multiple precast slabs 111 and further ensure the structural strength of the base plate 1.

[0093] In practical applications, when pouring the post-pouring strip 121 and the post-pouring slab 122, pouring templates can be set at the bottom and outer periphery of the annular space used to form the post-pouring slab 122, and at the bottom and inner periphery of the interval space, so as to avoid the overflow of the pouring medium.

[0094] It is understood that the bottom end of the side support 4 may be connected to the post-cast slab 122 by casting. In another embodiment of the present invention, the bottom end of the side support 4 may be connected to the post-cast strip 121 of the slab by casting.

[0096] like Figure 2 , Figure 4 and Figure 8 As shown, optionally, the bottom end of the side support member 4 may be provided with a plurality of first end connecting ribs 41. The first end connecting ribs 41 may extend from the bottom surface of the side support member 4 into the annular space. A plurality of annular ribs 123 may be provided in the annular space at intervals. The annular ribs 123 may be in the shape of a ring and surround the outer periphery of a plurality of precast slabs 111 connected by the slab post-pouring strip 121.

[0097] The annular reinforcement 123 may be configured as two rows, and the two rows of annular reinforcement 123 may be arranged at intervals in the vertical direction. Each row of annular reinforcement 123 may include multiple annular reinforcement 123 arranged in a radial direction from the inside to the outside and at intervals. The annular reinforcement 123 is used to be cast into the post-cast slab 122, thereby improving the strength of the post-cast slab 122.

[0098] The annular rib 123, as the first plate connecting rib, can be staggered with the first end connecting rib 41 and cast into the post-cast slab 122. Optionally, the upper row of annular ribs 123 can be staggered with the first end connecting rib 41 and cast into the post-cast slab 122, thereby ensuring the reliability and stability of the connection between the side support 4 and the bottom plate 1.

[0099] In one embodiment of this utility model, the angle between the side support 4 and the cross-sectional direction of the base plate 1 can be 45° to 60°. For example, 45°, 50°, 55°, 60°, etc., to ensure that the side support 4 can distribute the bending moment of the base plate 1.
