Numerous specific details are set forth in the following detailed description to provide a comprehensive understanding of this application. However, it will be apparent to those skilled in the art that this application can be implemented without requiring some of these specific details. The following description of embodiments is merely intended to provide a better understanding of this application by illustrating examples. In the accompanying drawings and the following description, at least some well-known structures and techniques are not shown to avoid unnecessarily obscuring the application; and, for clarity, the dimensions of some structures may be exaggerated. Furthermore, the features, structures, or characteristics described below can be combined in any suitable manner in one or more embodiments.

[0122] The directional terms used in the following description refer to the directions shown in the figures and are not intended to limit the specific steps and structures of the support structure and its manufacturing method of this application. It should also be noted in the description of this application that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0123] like Figures 1 to 4 As shown in the figure, this application provides a support structure, wherein the support structure includes a bottom tower 1. Along the axial direction of the bottom tower 1, the bottom tower 1 includes multiple interconnected tower segments 11. The number of tower segments 11 can be flexibly adjusted according to the height of each tower segment 11 and the overall required height of the support structure.

[0124] Optionally, each tower section 11 has an axial dimension of about 30m to facilitate transportation and installation. For example, the bottom tower 1 with an axial dimension of 90m may include three tower sections 11, which are then transported to the installation site and welded together.

[0125] Each pair of adjacent tower sections 11 is connected by a connecting assembly 12 to enable the segmented transportation, storage and assembly of the bottom tower section 1.

[0126] The connecting assembly 12 includes a first connector 121 and a second connector 122 that are fixedly connected along the axial direction of the bottom tower section 1; the first connector 121 is fixedly connected to one of two adjacent tower sections 11; the second connector 122 is fixedly connected to the other of the two adjacent tower sections 11; that is, the first connector 121 and the second connector 122 are respectively connected to two adjacent tower sections 11.

During assembly, the two tower sections 11 can be accurately connected quickly and easily by interlocking the protrusion 1211 and the recess 1221, thereby improving the assembly efficiency of the bottom tower 1. At the same time, after the protrusion 1211 and the recess 1221 are assembled, the structural strength between the two tower sections 11 can be increased radially along the bottom tower 1, thereby improving the overall structural strength of the bottom tower 1, reducing the impact of wind power load on the tower, and reducing the frequency of maintenance and the workload of maintenance personnel.

[0129] Optionally, along the direction from the first connector 121 to the second connector 122, the cross-sectional dimension of the protrusion 1211 along the radial direction of the tower section 11 and the end face dimension of the recess 1221 along the radial direction of the tower section 11 are both gradually reduced to form a cone shape, so as to facilitate the rapid insertion and engagement of the protrusion 1211 and the recess 1221.

The first ring portion 1214 is fixedly connected to the first inner ring plate 1212 and the first outer ring plate 1213 respectively. A protrusion 1211 is formed on one side surface of the first ring portion 1214 along its axial direction.

[0131] The first inner ring plate 1212 and the first outer ring plate 1213 are both made of metal, such as steel; the first ring portion 1214 and the protrusion portion 1211 are formed by concrete pouring and curing.

[0132] like Figure 7 and Figure 8As shown, according to one aspect of the embodiments of this application, the second connector 122 includes a second inner ring plate 1222 and a second outer ring plate 1223. The second outer ring plate 1223 is coaxially sleeved on the outside of the second inner ring plate 1222. A second ring portion 1224 is provided between the second inner ring plate 1222 and the second outer ring plate 1223. The second ring portion 1224 is fixedly connected to the second inner ring plate 1222 and the second outer ring plate 1223 respectively. A recess 1221 is formed on one side surface of the second ring portion 1224 along its axial direction.

[0133] The second inner ring plate 1222 and the second outer ring plate 1223 are both made of metal, such as steel; the second ring portion 1224 and the recess 1221 are formed by concrete pouring and curing.

[0134] like Figure 9 and Figure 10 As shown, according to one aspect of the embodiments of this application, the first inner ring plate 1212 and the second inner ring plate 1222 are connected along the axial direction of the bottom tower 1, and the first outer ring plate 1213 and the second outer ring plate 1223 are connected along the axial direction of the bottom tower 1, so as to form a smooth inner surface and an outer surface after the first connector 121 and the second connector 122 are connected.

[0135] The surface of the first ring portion 1214 facing the second connector 122 is flush with the edge of the first inner ring plate 1212 near the second connector 122 and the edge of the first outer ring plate 1213 near the second connector 122. The protrusion 1211 protrudes from the surface of the first ring portion 1214 facing the second connector 122.

[0136] The surface of the second ring portion 1224 facing the first connector 121 is flush with the edge of the second inner ring plate 1222 near the first connector 121 and the edge of the second outer ring plate 1223 near the first connector 121. The recess 1221 is recessed on the surface of the second ring portion 1224 facing the first connector 121.

[0137] A stepped surface is formed on both the side of the first connector 121 facing the second connector 122 and the side of the second connector 122 facing the first connector 121. When the protrusion 1211 and the recess 1221 are engaged, not only the outer surface of the protrusion 1211 is in contact with the inner surface of the recess 1221, but also a portion of the plane is in contact, so as to further increase the connection area between the first connector 121 and the second connector 122 and improve the connection strength between them.

[0138] like Figure 2 and Figure 11 As shown, according to one aspect of the embodiments of this application, the tower section 11 includes a plurality of cylindrical sections 111 connected axially along the bottom tower section 1, and optionally, every two adjacent cylindrical sections 111 are welded and fixed together.

[0139] Each cylindrical section 111 includes an inner cylinder 1111, an outer cylinder 1112, and a core 1113. The outer cylinder 1112 is coaxially sleeved on the outside of the inner cylinder 1111. The core 1113 is located between the inner cylinder 1111 and the outer cylinder 1112, and the core 1113 is fixedly connected to both the inner cylinder 1111 and the outer cylinder 1112.

[0140] Both the inner cylinder 1111 and the outer cylinder 1112 are made of metal, such as steel; the core 1113 is formed by concrete pouring and curing. The cylinder section 111, the tower section 11, and the bottom tower 1, which are formed by the combination of steel cylinder and concrete, fully combine the advantages of both. On the one hand, the steel cylinder's restriction on concrete cracking under pressure increases the concrete's bearing capacity; on the other hand, the presence of concrete makes the steel cylinder less prone to buckling, which also greatly increases the steel cylinder's bearing capacity.

[0141] With the first connector 121 fixedly connected to one end of the tower section 11, the first inner ring plate 1212 is connected to the inner cylinder 1111 of the cylinder section 111 located at one end of the tower section 11, the first outer ring plate 1213 is connected to the outer cylinder 1112 of the cylinder section 111 located at one end of the tower section 11, and the first ring portion 1214 is connected to the cylinder core 1113 of the cylinder section 111 located at one end of the tower section 11.

[0142] While connecting the first connector 121 to the tower section 11, the inner surface of the first connector 121 is flush with the inner surface of the tower section 11, and the outer surface of the first connector 121 is flush with the outer surface of the tower section 11, thereby ensuring a smooth connection between the first connector 121 and the tower section 11.

[0143] With the second connector 122 fixedly connected to the other end of the tower section 11, the second inner ring plate 1222 is connected to the inner cylinder 1111 of the cylinder section 111 located at the other end of the tower section 11, the second outer ring plate 1223 is connected to the outer cylinder 1112 of the cylinder section 111 located at the other end of the tower section 11, and the second ring portion 1224 is connected to the cylinder core 1113 of the cylinder section 111 located at the other end of the tower section 11.

[0144] While connecting the second connector 122 to the tower section 11, the inner surface of the second connector 122 is flush with the inner surface of the tower section 11, and the outer surface of the second connector 122 is flush with the outer surface of the tower section 11, thereby ensuring a smooth connection between the second connector 122 and the tower section 11.

[0145] like Figure 9 and Figure 10As shown, according to one aspect of the embodiments of this application, the first ring portion 1214 and the corresponding core 1113 and the second ring portion 1224 and the corresponding core 1113 are bonded and fixed by an adhesive layer 123 to ensure the connection strength between the first ring portion 1214 and the core 1113 and between the second ring portion 1224 and the core 1113.

[0146] Optionally, the adhesive layer 123 is formed by curing a high-strength grout.

[0147] like Figure 12 As shown, both the inner cylinder 1111 and the outer cylinder 1112 are steel cylinders formed by rolling and welding steel plates.

[0148] Optionally, such as Figure 13 As shown, the inner cylinder 1111 and the outer cylinder 1112 can be formed by welding and fixing multiple steel cylinders.

[0149] The axial dimension of tower section 11 is approximately 30m. However, due to the difficulty in controlling the pouring quality at 30m, calculations and analysis, combined with the characteristics of concrete fluidity, suggest that an axial dimension of approximately 9m is a more reasonable pouring length. Therefore, each section 111 is approximately 9m long. Section 111 can be prefabricated and used directly when manufacturing the bottom tower 1, eliminating the 28-day curing period required for on-site concrete pouring and thus shortening the manufacturing cycle of the bottom tower 1.

[0150] like Figure 14 and Figure 15 As shown, according to one aspect of the embodiments of this application, reinforcing members are provided on the inner surface of the inner cylinder 1111, the outer surface of the inner cylinder 1111, the inner surface of the outer cylinder 1112, and / or the outer surface of the outer cylinder 1112 to improve the structural strength of the inner cylinder 1111 and the outer cylinder 1112.

[0151] Optionally, such as Figure 14 and Figure 15 As shown, the reinforcing member is a reinforcing rib, which extends axially along the bottom tower 1 and / or extends circumferentially along the bottom tower 1.

[0152] The inner surface of the inner cylinder 1111 is provided with a plurality of annular reinforcing ribs 11111 that extend in the circumference to form an annular structure. The plurality of annular reinforcing ribs 11111 are spaced apart along the axial direction of the inner cylinder 1111 to improve the circumferential structural strength of the inner cylinder 1111.

[0153] The outer surface of the inner cylinder 1111 is provided with a plurality of first strip reinforcing ribs 11112 extending along its axial direction. The plurality of first strip reinforcing ribs 11112 are arranged at intervals along the circumference of the inner cylinder 1111 to improve the axial structural strength of the inner cylinder 1111.

[0154] The inner surface of the outer cylinder 1112 is provided with a plurality of second strip-shaped reinforcing ribs 11121 extending along its axial direction. The plurality of second strip-shaped reinforcing ribs 11121 are arranged at intervals along the circumference of the outer cylinder 1112 to improve the axial structural strength of the outer cylinder 1112.

[0155] Axially extending reinforcing ribs are provided on the inner surface of the outer cylinder 1112 and the outer surface of the inner cylinder 1111. When concrete is poured between the inner cylinder 1111 and the outer cylinder 1112, it is beneficial to the flow of concrete and ensures that the concrete is fully filled between the inner cylinder 1111 and the outer cylinder 1112.

[0156] Optionally, the first strip reinforcing rib 11112 and the second strip reinforcing rib 11121 are alternately arranged to ensure uniform structural strength of the cylinder section 111.

[0157] According to one aspect of the embodiments of this application, each cylindrical section 111 has a core 1113 with multiple through holes, each through hole extending axially along the core 1113 and penetrating both ends of the core 1113 along its axial direction, and the multiple through holes are spaced apart circumferentially along the core 1113; the through holes of each cylindrical section 111 of each tower section 11 are connected one-to-one to form multiple prestressing channels 1114, and the multiple prestressing channels 1114 are spaced apart circumferentially along the tower section 11; at least a portion of the prestressing channels 1114 are provided with prestressing cables 1115, and the two ends of the prestressing cables 1115 are respectively fixed to the two ends of the tower section 11 along its axial direction. By providing prestressing channels 1114 and prestressing cables 1115, the structural strength of the tower section 11 can be further improved.

[0158] like Figure 16 and Figure 17 As shown, according to one aspect of the embodiments of this application, a plurality of flexible tubes 11141 are embedded in the core 1113 of each cylindrical section 111. The flexible tubes 11141 extend along the axial direction of the core 1113 and penetrate both ends of the core 1113 along its axial direction. The plurality of flexible tubes 11141 are arranged at intervals along the circumference of the core 1113. A prestressed channel 1114 is formed inside the flexible tubes 11141.

[0159] Before pouring the core 1113, a flexible tube 11141 is pre-installed between the outer cylinder 1112 and the inner cylinder 1111. Then, concrete is poured between the outer cylinder 1112 and the inner cylinder 1111. After the concrete has cured, the flexible tube 11141 is fixed.

[0160] Specifically, such as Figure 18As shown, the flexible tube 11141 is installed on the first strip reinforcing rib 11112 on the outer surface of the inner cylinder 1111 by positioning hooks 11142. Each flexible tube 11141 is installed by multiple positioning hooks 11142, and the multiple positioning hooks 11142 are spaced apart along the extension direction of the first strip reinforcing rib 11112.

[0161] According to one aspect of the embodiments of this application, anchors 1116 are respectively connected to both ends of the prestressed cable 1115, and the two anchors 1116 are respectively located at both ends of the axial direction of the tower section 11. The prestressed cable 1115 is tensioned between the two anchors 1116. Along the radial direction of the prestressed channel 1114, the size of the anchor 1116 is larger than the size of the prestressed channel 1114 to prevent the anchor 1116 from entering the prestressed channel 1114 and causing the prestressed cable 1115 to fail to be tensioned.

[0162] Anchor 1116 is embedded in adhesive layer 123, which fixes it and enhances its corrosion resistance.

[0163] Optionally, such as Figures 19 to 25 As shown, according to one aspect of the embodiment of this application, the cylindrical section 111 is provided with connecting ring pieces 1118 at both ends along its axial direction. The outer periphery of the connecting ring piece 1118 is fixedly connected to the outer cylinder 1112, the inner periphery of the connecting ring piece 1118 is fixedly connected to the inner cylinder 1111, and the connecting ring piece 1118 is fixedly connected to the cylinder core 1113.

[0164] Before pouring the core 1113, the inner cylinder 1111 and the outer cylinder 1112 are fixedly connected by two connecting rings 1118 to form a pouring space. The two connecting rings 1118 can maintain the relative position of the inner cylinder 1111 and the outer cylinder 1112 to ensure that the dimensions of the pouring space are uniform.

[0165] Two adjacent cylindrical sections 111 of each tower section 11 are fixedly connected by two connecting rings 1118 that are close to each other. By setting the connecting rings 1118, the connection area between the two adjacent cylindrical sections 111 can be increased to ensure the connection strength between the two cylindrical sections 111.

[0166] The connecting ring 1118 has multiple through holes 11181 spaced apart along its circumference. Each through hole 11181 is connected to a prestressed channel 1114 so that the prestressed cable 1115 can pass through.

[0167] Along the radial direction of the through hole 11181, the maximum size of the anchor 1116 is larger than the diameter of the through hole 11181, and when the prestressed cable 1115 is tensioned, the anchor 1116 is confined to the side of the connecting ring 1118 away from the core 1113.

[0168] Alternatively, the anchor 1116 is embedded in the through hole 11181, and the maximum size of the anchor 1116 is larger than the inner diameter of the prestressed channel 1114 along the radial direction of the through hole 11181, so as to confine the anchor 1116 to the axial end face of the core 1113.

[0169] like Figures 19 to 25 As shown, according to one aspect of the embodiment of this application, the connecting ring 1118 is provided with a casting hole 11182 to facilitate the casting of the core 1113.

[0170] Optionally, such as Figure 24 and Figure 25 As shown, a prestress transfer layer 1117 is provided in the prestress channel 1114. The prestress transfer layer 1117 covers the prestress cable 1115 and is fixedly connected to the inner surface of the prestress channel 1114.

[0171] like Figure 26 and Figure 27 As shown, according to one aspect of the embodiments of this application, the support structure further includes a top tower 2, which is located at the first end of the bottom tower 1 along its axial direction; since the top is subjected to less force, the top tower 2 is a steel structure tower.

[0172] The bottom tower 1 is connected to a first flange 21 at its first end, and the top tower 2 is connected to the end of the bottom tower 1 with a second flange 22. The first flange 21 and the second flange 22 are detachably connected by bolts or other fasteners.

[0173] Both the first flange 21 and the second flange 22 are provided with connection holes. The connection holes of the first flange 21 and the second flange 22 are located on the inside, so as to facilitate the maintenance and repair of the support structure by the staff inside.

[0174] like Figure 1 and Figure 28 As shown, according to one aspect of the embodiments of this application, the support structure further includes a foundation 3, and the second end of the bottom tower 1 along its axial direction is connected to the foundation 3 through a connecting component 12, so as to facilitate the quick and convenient accurate assembly of the bottom tower 1 and the foundation 3.

[0175] The second end of the bottom tower 1 is connected to one of the first connector 121 and the second connector 122, and the other of the first connector 121 and the second connector 122 is provided on the foundation 3.

[0176] like Figure 28 As shown, according to one aspect of the embodiments of this application, the base 3 is formed with a platform, and a positioning cylinder 31 is fixedly provided on the platform. The first connector 121 or the second connector 122 is connected to the positioning cylinder 31, and the projection of the first connector 121 or the second connector 122 falls into the projection of the positioning cylinder 31 along the circumference of the positioning cylinder 31.

[0177] Specifically, the positioning cylinder 31 is connected to and flush with the first outer ring plate 1213 of the first connector 121 or the second outer ring plate 1223 of the second connector 122 to ensure that the support structure has a smooth outer surface.

[0178] like Figure 28 As shown, according to one aspect of an embodiment of this application, a support column 32 is provided between the first connector 121 or the second connector 122 and the positioning cylinder 31. Along the direction from the base 3 to the bottom tower cylinder 1, the support column 32 is inclined towards the axis of the bottom tower cylinder 1. One end of the support column 32 is in contact with the inner surface of the positioning cylinder 31, and the other end of the support column 32 is in contact with the first connector 121 or the second connector 122. By providing the support column 32, the first connector 121 or the second connector 122 connected to the positioning cylinder 31 can be supported, thereby improving the connection strength between the positioning cylinder 31 and the bottom tower cylinder 1.

[0179] This application also provides a method for manufacturing a support structure, wherein the method for manufacturing the support structure includes:

[0180] Manufacturing the bottom tower 1 includes:

[0181] Multiple tower sections 11 are set up, each with an axial dimension of about 30m to facilitate transportation and installation. For example, the bottom tower 1 with an axial dimension of 90m can include three tower sections 11. The three tower sections 11 are transported to the installation site and then welded together. Specifically, the number of tower sections 11 can be flexibly adjusted according to the height of each tower section 11 and the overall height required by the support structure.

[0182] A connecting assembly 12 is provided with a first connector 121 and a second connector 122, such that the first connector 121 has a protrusion 1211 and the second connector 122 has a recess 1221.

[0183] A connecting assembly 12 is provided between every two adjacent tower sections 11, with the first connector 121 of each connecting assembly 12 connected to one of the two adjacent tower sections 11, and the second connector 122 of each connecting assembly 12 connected to the other of the two adjacent tower sections 11.

[0184] The protrusion 1211 of the first connector 121 of each connecting component 12 is engaged with the recess 1221 of the corresponding second connector 122, and the first connector 121 and the second connector 122 of each set of connecting components 12 are fixedly connected; that is, the first connector 121 and the second connector 122 are respectively connected to two adjacent tower sections 11. During assembly, the two tower sections 11 are assembled by connecting the first connector 121 and the second connector 122.

[0185] The manufacturing method of the support component provided in this application embodiment connects the first connector 121 and the second connector 122 to two adjacent tower sections 11 respectively. The first connector 121 has a protrusion 1211 and the second connector 122 has a recess 1221. During assembly, the engagement of the protrusion 1211 and the recess 1221 can easily and quickly achieve precise docking of the two tower sections 11, thereby improving the assembly efficiency of the bottom tower 1. At the same time, after the protrusion 1211 and the recess 1221 are assembled, the structural strength between the two tower sections 11 can be increased radially along the bottom tower 1, thereby improving the overall structural strength of the bottom tower 1, reducing the impact of wind power load on the tower, and reducing the frequency of maintenance and the workload of maintenance personnel.

[0186] According to one aspect of the embodiments of this application, a connecting assembly 12 having a first connector 121 and a second connector 122 is provided, such that the first connector 121 has a protrusion 1211 and the second connector 122 has a recess 1221, including:

The first inner ring plate 1212 and the first outer ring plate 1213 are formed by rolling steel plates, so that the first outer ring plate 1213 is coaxially sleeved on the outside of the first inner ring plate 1212.

[0188] A second inner ring plate 1222 and a second outer ring plate 1223 are provided. The second inner ring plate 1222 and the second outer ring plate 1223 are formed by rolling steel plates, so that the second outer ring plate 1223 is coaxially sleeved on the outside of the second inner ring plate 1222.

[0189] A second ring portion 1224 is provided between the second inner ring plate 1222 and the second outer ring plate 1223, and a first ring portion 1214 is provided between the first inner ring plate 1212 and the first outer ring plate 1213.

[0192] A bottom template is provided between the second inner ring plate 1222 and the second outer ring plate 1223. The bottom template has an annular sheet structure. The inner edge of the bottom template is sealed and fixedly connected to the second inner ring plate 1222, and the outer edge of the bottom template is sealed and fixedly connected to the second outer ring plate 1223.

[0193] The bottom template is made of steel plate, and the bottom template is fixed to the first inner ring plate 1212 and the bottom template is fixed to the first outer ring plate 1213 by welding.

[0194] A middle template is provided between the second inner ring plate 1222 and the second outer ring plate 1223. The middle template has a ring structure. The inner edge of the middle template is fixedly connected to the connection between the first inner ring plate 1212 and the second inner ring plate 1222 by spot welding. The outer edge of the middle template is fixedly connected to the connection between the first outer ring plate 1213 and the second outer ring plate 1223 by spot welding, so as to facilitate the connection and disassembly of the middle template.

[0195] A ring groove is formed on the middle template. The second inner ring plate 1222, the second outer ring plate 1223, the bottom template and the middle template enclose and form a first cavity. The groove wall and / or the bottom of the ring groove are provided with through holes that communicate with the first cavity.

[0196] Liquid concrete is injected into the annular groove. The liquid concrete flows into and fills the first cavity through the through hole. After the liquid concrete filling the first cavity solidifies, it forms the second annular part 1224.

[0197] Release agent is applied to the surface of the bottom template facing the middle template and the surface of the middle template facing the bottom template, so that the bottom template and the middle template can be easily separated from the second ring 1224 after the second ring 1224 is cured.

[0198] According to one aspect of the embodiments of this application, a first ring portion 1214 is provided between the first inner ring plate 1212 and the first outer ring plate 1213, including:

[0199] Partitions are installed at each through hole of the middle template, with each partition covering the through hole to seal it.

[0200] Liquid concrete is injected between the first inner ring plate 1212 and the first outer ring plate 1213 above the middle template. After the liquid concrete filling the space between the first inner ring plate 1212 and the first outer ring plate 1213 solidifies, it forms the first ring portion 1214.

[0201] Both sides of the partition and the side of the middle template facing away from the bottom template are coated with a release agent to facilitate the separation of the middle template and the partition from the first ring 1214 after the first ring 1214 has been cured.

[0202] According to one aspect of the embodiments of this application, after forming the first ring portion 1214 and the second ring portion 1224, a connecting assembly 12 having a first connector 121 and a second connector 122 is provided, such that the first connector 121 has a protrusion 1211 and the second connector 122 has a recess 1221, and the assembly further includes:

[0203] Separate the first inner ring plate 1212 from the second inner ring plate 1222, separate the first outer ring plate 1213 from the second outer ring plate 1223, separate the middle template and partition from the first ring portion 1214, separate the middle template and partition from the second ring portion 1224, and separate the bottom template from the second ring portion 1224, the second inner ring plate 1222, and the second outer ring plate 1223 to form a first connector 121 and a second connector 122 that are independent of each other and can be connected.

[0204] Since the first inner ring plate 1212 and the second inner ring plate 1222, as well as the first outer ring plate 1213 and the second outer ring plate 1223, are welded together, and the first ring portion 1214 and the second ring portion 1224 are formed by the curing of liquid concrete, the first connector 121 and the second connector 122 have good rigidity. After the first inner ring plate 1212 and the second inner ring plate 1222 are separated, and the first outer ring plate 1213 and the second outer ring plate 1223 are separated, the first connector 121 and the second connector 122 will not deform, which facilitates on-site docking.

[0205] According to one aspect of the embodiments of this application, a predetermined distance is formed between the second ring portion 1224 and the side edge of the second inner ring plate 1222 away from the first inner ring plate 1212, between the second ring portion 1224 and the side edge of the second outer ring plate 1223 away from the first outer ring plate 1213, between the first ring portion 1214 and the side edge of the first inner ring plate 1212 away from the second inner ring plate 1222, and between the first ring portion 1214 and the side edge of the first outer ring plate 1213 away from the second outer ring plate 1223, so that after the first connector 121 and the second connector 122 are connected to the tower section 11, a gap is formed between the end of the first ring portion 1214 and the end of the tower section 11, and between the second ring portion 1224 and the end of the tower section 11. In subsequent steps, an adhesive layer 123 can be provided in the gap to improve the connection strength between the first ring portion 1214 and the tower section 11 and between the second ring portion 1224 and the tower section 11.

[0207] With the side of the first ring portion 1214 away from the corresponding second connector 122 facing upward, liquid grout is injected between the first ring portion 1214, the first inner ring plate 1212, and the first outer ring plate 1213, so that one end of the tower section 11 along its axial direction is coaxially connected with the first connector 121 above it. After the liquid grout has solidified, the first connector 121 is bonded and fixed to one end of the tower section 11.

[0208] With the side of the second ring portion 1224 away from the corresponding first connector 121 facing upwards, liquid grout is injected between the second ring portion 1224, the second inner ring plate 1222, and the second outer ring plate 1223, so that one end of the tower section 11 along its axial direction is coaxially connected with the second connector 122 above it. After the liquid grout has solidified, the second connector 122 is bonded and fixed to the other end of the tower section 11.

[0209] Liquid grouting material is a high-strength grouting material that has good structural strength and bonding performance after curing.

[0210] According to one aspect of the embodiments of this application, a connecting assembly 12 is provided between every two adjacent tower sections 11, wherein a first connector 121 of each connecting assembly 12 is connected to one of the two adjacent tower sections 11, and a second connector 122 of each connecting assembly 12 is connected to the other of the two adjacent tower sections 11, further comprising:

[0211] The first inner ring plate 1212, the first outer ring plate 1213, the second inner ring plate 1222, and the second outer ring plate 1223 are welded and fixed to the corresponding tower section 11, respectively. Specifically, the inner surfaces of the first inner ring plate 1212 and the second inner ring plate 1222 are flush with the inner surface of the tower section 11, and the outer surfaces of the first outer ring plate 1213 and the second outer ring plate 1223 are flush with the outer surface of the tower section 11, so as to ensure the flatness of the overall inner and outer surfaces of the bottom tower 1.

[0212] According to one aspect of an embodiment of this application, the tower section 11 includes:

[0213] Manufacture cylindrical section 111, arrange multiple cylindrical sections 111 along its axial direction and weld them together;

[0214] Manufacturing section 111 includes:

[0215] A plurality of first cylinders are formed by winding and fixing sheet metal (optional steel plate), and at least two first cylinders are fixedly connected along their axial direction to form an inner cylinder 1111.

[0216] A plurality of second cylinders are formed by winding and fixing a sheet (optional steel plate), and at least two second cylinders are fixedly connected along their axial direction to form an outer cylinder 1112;

[0217] Multiple first cylinders and multiple second cylinders are fixed by welding. The welding method can be horizontal welding, that is, two first cylinders or two second cylinders are coaxially stacked in the vertical direction and the two first cylinders or second cylinders aligned vertically are welded and fixed; or the welding method between multiple first cylinders and multiple second cylinders can be flat welding, that is, the axial direction of each first cylinder and each second cylinder extends in the horizontal direction. However, it should be noted that since the diameter-to-thickness ratio of the first cylinder and the second cylinder is very large, anti-deformation tooling needs to be set when performing flat welding to prevent the first cylinder and the second cylinder from deforming.

[0218] A ring-shaped reinforcing rib 11111 is provided on the inner surface of the inner cylinder 1111, a first strip-shaped reinforcing rib 11112 extending axially is provided on the outer surface of the inner cylinder 1111, and a second strip-shaped reinforcing rib 11121 extending axially is provided on the inner surface of the outer cylinder 1112. The use of only strip-shaped reinforcing ribs in the pouring space is conducive to the flow of concrete, and at the same time improves the structural strength of the inner cylinder 1111 and the outer cylinder 1112, thus avoiding the bottom tower 1 from being damaged by stress.

[0219] Optionally, the first strip reinforcing rib 11112 and the second strip reinforcing rib 11121 are alternately arranged to ensure uniform structural strength of the cylinder section 111.

[0220] A first connecting ring is set on a horizontal plane. One end of the inner cylinder 1111 is welded and fixed to the inner edge of the first connecting ring. The outer cylinder 1112 is sleeved on the outside of the inner cylinder 1111. One end of the outer cylinder 1112 is welded and fixed to the outer edge of the first connecting ring.

[0221] The other end of the outer cylinder 1112 is welded and fixed to the outer edge of the second connecting ring piece, and the other end of the inner cylinder 1111 is welded and fixed to the inner edge of the second connecting ring piece, so that the first connecting ring piece, the second connecting ring piece, the inner cylinder 1111 and the outer cylinder 1112 enclose and form a casting space.

[0222] Liquid concrete is filled into the pouring space. After the liquid concrete solidifies, a core 1113 is formed. The core 1113 is fixedly connected to the first connecting ring, the second connecting ring, the inner cylinder 1111, and the outer cylinder 1112.

[0223] The axial dimension of tower section 11 is approximately 30m. However, due to the difficulty in controlling the pouring quality at 30m, after calculation and analysis considering the fluidity of concrete, an axial dimension of approximately 9m is deemed a more reasonable pouring length. Therefore, each section 111 is approximately 9m long. Sections 111 can be prefabricated, and multiple sections 111 can be poured and cured simultaneously. They can then be used directly when manufacturing the bottom tower 1, eliminating the 28-day curing period required for on-site concrete pouring and thus shortening the manufacturing cycle of the bottom tower 1.

[0224] According to one aspect of the embodiments of this application, before filling the casting space with liquid concrete, the method further includes:

[0225] Multiple flexible tubes 11141 are placed in the casting space. The flexible tubes 11141 extend along the axial direction of the tower section 11. The two ends of each flexible tube 11141 are connected to the first connecting ring and the second connecting ring, respectively. The multiple flexible tubes 11141 are spaced apart along the circumference of the tower section 11.

[0226] Prestressed cables 1115 are inserted inside each flexible tube 11141, and anchors 1116 are respectively installed at the first connecting ring and the second connecting ring. The two ends of the prestressed cables 1115 are fixedly connected to the two anchors 1116 respectively, and the prestressed cables 1115 are tensioned to improve the structural strength of the tower section 11.

[0227] According to one aspect of the embodiments of this application, after the prestressed cable 1115 is tensioned, liquid grout is filled into the flexible tube 11141, and after the liquid grout solidifies, a prestress transfer layer 1117 is formed to optimize the uniform stress distribution of the tower section 11.

[0228] According to one aspect of the embodiments of this application, the above are the design and manufacturing steps of the bottom tower 1. The top of the bottom tower 1 is connected to the top tower 2, and the bottom of the bottom tower 1 is connected to the foundation 3. The manufacturing method of the support structure further includes:

[0229] A first flange 21 is provided at one end of the bottom tower 1, and a second flange 22 is provided at one section of the top tower 2. The first flange 21 and the second flange 22 are connected by bolts or other fasteners.

[0230] The other end of the bottom tower 1 is fixedly connected to the foundation 3 via connecting assembly 12 to form a complete support structure. Since the diameter of the connection between the bottom tower 1 and the foundation 3 is relatively large, the flange production cost is very high. Furthermore, the connection between the bottom tower 1 and the foundation 3 can be easily achieved using automatic welding. Therefore, connecting assembly 12 is provided to connect to both the bottom tower 1 and the foundation 3 before assembly. Based on the stress conditions between the bottom tower 1 and the foundation 3, a bracket can be installed to enhance the structural strength of the connection point.

[0231] Although this application has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of this application. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
