Description

Technical Field

[0001] This invention relates to the field of bridge construction technology, and more specifically, to a method for assembling steel tower segments. Background Technology

[0002] A cable-stayed bridge, also known as a spur bridge, mainly consists of towers, a main girder, and stay cables. It's a type of bridge where the main girder is directly anchored to the towers using multiple stay cables. The stay cables, utilizing the stability of a triangle, form a triangle with the towers and main girder, transferring the forces on the main girder to the towers. The towers, in turn, bear the weight of the main girder and any objects on it. The taller the tower, the greater the inclination angle of the stay cables, and the greater the force the main girder can withstand.

[0003] Therefore, in the construction of large bridges, such as extra-large cable-stayed steel structure bridges, the pylons, or steel towers, have a large structural volume, and the overall construction is quite difficult. Generally, the steel towers are divided into multiple segments, and the installation of the steel towers is completed by manufacturing the segments first and then connecting them as a whole.

[0004] However, errors are prone to occur during the individual manufacturing and overall connection of multiple steel tower segments. In particular, errors occurring during the individual manufacturing of steel tower segments can accumulate during the overall connection of steel tower segments, seriously affecting the construction and installation accuracy of the steel tower and potentially adversely affecting the overall construction quality of the bridge and its post-construction stability. Summary of the Invention

[0005] The problem addressed by this invention is how to improve the manufacturing precision of steel tower segments and the overall construction and installation precision of the steel tower, so as to ensure the overall construction quality of the bridge and its stability after handover.

[0006] To address the above problems, this invention provides a method for assembling steel tower segments, the method comprising:

[0007] The steel tower segment is divided into a central anchor chamber module, a side anchor chamber module, and a side box chamber module, and the central anchor chamber module, the side anchor chamber module, and the side box chamber module are fabricated respectively.

[0008] The central anchor chamber module is placed on the main assembly frame, and two side anchor chamber modules are installed on both sides of the central anchor chamber module, with the central anchor chamber module as the reference.

[0009] Based on the central anchor chamber module and the side anchor chamber module, the side box chamber module is installed on the side of the side anchor chamber module that is away from the central anchor chamber module;

[0010] The central anchor chamber module, the side anchor chamber module, and the side box chamber module are welded and fixed in sequence.

[0011] Compared to existing technologies, the beneficial effects of this invention include: First, the steel tower segments that need to be manufactured separately are divided into a central anchor chamber module, a side box chamber module, and a side anchor chamber module, and these modules are manufactured separately. Since the central anchor chamber module, side box chamber module, and side anchor chamber module can be manufactured simultaneously, the manufacturing time of the separately manufactured steel tower segments can be effectively shortened, thus effectively improving the manufacturing efficiency of the steel tower segments. Second, the manufactured central anchor chamber module is placed on the main assembly frame, and using the central anchor chamber module as a reference, the two side anchor chamber modules are respectively installed on both sides of the central anchor chamber module. Using the central anchor chamber module and the side anchor chamber module as references, the side box chamber module is installed on the side of the side anchor chamber module away from the central anchor chamber module, thus completing the initial assembly of the steel tower segment. Since the assembly is carried out sequentially in the same direction, the assembly accuracy of the initially assembled steel tower segment is relatively reliable, effectively ensuring the manufacturing accuracy of the assembled steel tower segment. Finally, the central anchor chamber module, the side anchor chamber module, and the side box chamber module are welded and fixed in sequence to obtain a steel tower segment with high manufacturing accuracy that can meet the overall construction and installation accuracy of the steel tower, ensuring the overall construction quality of the bridge and its stability after handover.

Detailed Implementation

[0049] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0050] It should be noted that in the XYZ coordinate system provided herein, the positive direction of the X-axis represents the right, and the negative direction of the X-axis represents the left; the positive direction of the Y-axis represents the rear, and the negative direction of the Y-axis represents the front; the positive direction of the Z-axis represents the top, and the negative direction of the Z-axis represents the bottom. Furthermore, it should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0051] A method for assembling steel tower segments includes: dividing the steel tower segment into a central anchor chamber module 1, a side anchor chamber module 3, and a side box chamber module 2, and preparing the central anchor chamber module 1, the side anchor chamber module 3, and the side box chamber module 2 respectively; placing the central anchor chamber module 1 on a general assembly jig, and installing two side anchor chamber modules 3 on both sides of the central anchor chamber module 1, using the central anchor chamber module 1 as a reference; installing the side box chamber module 2 on the side of the side anchor chamber module 3 facing away from the central anchor chamber module 1, using the central anchor chamber module 1 and the side anchor chamber module 3 as references; and welding the central anchor chamber module 1, the side anchor chamber module 3, and the side box chamber module 2 in sequence.

[0052] In this embodiment, as Figure 1 S1 to S4 and Figure 2 As shown, in step S1, the steel tower segments that need to be manufactured separately are divided into a central anchor chamber module 1, a side box chamber module 2, and a side anchor chamber module 3, and these modules are manufactured separately. Since the central anchor chamber module 1, side box chamber module 2, and side anchor chamber module 3 can be manufactured simultaneously, the manufacturing time of the separately manufactured steel tower segments can be effectively shortened, thus effectively improving the manufacturing efficiency of the steel tower segments. In step S2, the manufactured central anchor chamber module 1 can be placed on the main assembly frame, and with the central anchor chamber module 1 as the reference, the two side anchor chamber modules 3 are respectively installed on both sides of the central anchor chamber module 1. In step S3, using the central anchor chamber module 1 and the side anchor chamber module 3 as references, the side box chamber module 2 is installed on the side of the side anchor chamber module 3 away from the central anchor chamber module 1, thus completing the preliminary assembly of the steel tower segment. Since the assembly is carried out sequentially in the same direction, the assembly accuracy of the preliminarily assembled steel tower segment is relatively reliable. Based on this, in step S4, the central anchor chamber module 1, the side anchor chamber module 3, and the side box chamber module 2 are welded and fixed in sequence to obtain a steel tower segment with high manufacturing precision that can meet the overall construction and installation accuracy of the steel tower, ensuring the overall construction quality of the bridge and its stability after handover.

[0053] It should be noted that in this embodiment, the division of each module of the steel tower segment is based on minimizing the structure at the connection between adjacent modules, so as to reduce stress concentration after welding and fixing at the connection and improve structural stability.

[0054] In addition, in the embodiments of the various modules of the steel tower segment described below, the "partition" is used to be horizontally arranged in the steel tower segment, for example, the first partition 13, the second partition 21, and the third partition 32; the "wall panel" is used to be vertically arranged in the steel tower segment and is used to form the outer structure of the steel tower segment, for example, the first wall panel 11, the second wall panel 22, and the third wall panel 33; the "anchor plate" is used to be vertically arranged in the steel tower segment and is used inside the steel tower segment, for example, the first anchor plate 12 and the third anchor plate 31.

[0055] Optionally, before installing two side anchor chamber modules 3 on both sides of the central anchor chamber module 1, the steel tower segment assembly method further includes obtaining first parameter data of the central anchor chamber module 1, determining whether the first parameter data is within a first preset range, and if so, installing the side anchor chamber module 3; before installing the side box chamber module 2 on the side of the side anchor chamber module 3 away from the central anchor chamber module 1, the steel tower segment assembly method further includes: obtaining second parameter data of the side anchor chamber module 3, determining whether the second parameter data is within a second preset range, and if so, installing the side box chamber module 2; before sequentially welding and fixing the central anchor chamber module 1, the side anchor chamber module 3, and the side box chamber module 2, the steel tower segment assembly method further includes: obtaining third parameter data of the side box chamber module 2, determining whether the third parameter data is within a third preset range, and if so, welding and fixing; wherein, the first parameter data, the second parameter data, and the third parameter data all include at least one of verticality, box opening size, and gap size between adjacent plate structures.

[0056] It should be noted that, in this embodiment, verticality refers to the angle between intersecting structural plates in each module. Taking one structural plate as a reference, when the angle between another structural plate and it is 90 degrees, the verticality meets the requirements, ensuring the structural accuracy between perpendicularly intersecting plate structures. The box opening size is the design size. Under the premise of meeting the design error, the box opening size is ensured to be within the preset range, thereby ensuring the docking accuracy between adjacent modules. The gap size between adjacent plate structures is within the preset range, which can ensure that the gap between adjacent plate structures is not too large, thereby ensuring the manufacturing accuracy of each module and steel tower segment after assembly.

[0057] In this embodiment, after placing the middle anchor chamber module 1 on the assembly jig, the middle anchor chamber module 1 can be measured to obtain its first parameter data. The first parameter data is then judged to determine whether it falls within a first preset range, thus determining whether the manufacturing precision of the middle anchor chamber module 1 meets the requirements. If the first parameter data falls within the first preset range, it indicates that the manufacturing precision of the middle anchor chamber module 1 meets the requirements. At this time, the side anchor chamber modules 3 are assembled using the middle anchor chamber module 1, whose manufacturing precision meets the requirements, as the initial reference, ensuring the assembly precision of the side anchor chamber modules 3. Simultaneously, the side anchor chamber modules 3 can be measured to obtain their second parameter data. The second parameter data is then judged to determine whether it falls within a second preset range, thus determining whether the manufacturing precision of the side anchor chamber modules 3 meets the requirements. If the second parameter data falls within the second preset range, it indicates that the manufacturing precision of the middle anchor chamber module 3 meets the requirements. If the manufacturing accuracy is within the preset range, it indicates that the manufacturing precision of the side anchor chamber module 3 meets the requirements. Finally, using the middle anchor chamber module 1 and the side anchor chamber module 3, which meet the manufacturing precision requirements, as a benchmark, the side box chamber module 2 is assembled to ensure the assembly precision of the side box chamber module 2. After the side box chamber module 2 is assembled, it can be measured to obtain the third parameter data of the side box chamber module 2. The third parameter data is judged to determine whether it is within the third preset range, so as to determine whether the manufacturing precision of the side box chamber module 2 meets the requirements. If the third parameter data is within the third preset range, it indicates that the manufacturing precision of the side box chamber module 2 meets the requirements. When the manufacturing precision of the middle anchor chamber module 1 and the side anchor chamber module 3 both meet the requirements, and the manufacturing precision of the side box chamber module 2 also meets the requirements, the manufacturing precision of the assembled steel tower segment can be effectively guaranteed.

[0058] It should be noted that in other embodiments of the present invention, the first parameter data, the second parameter data, and the third parameter data may include other parameter types such as the diagonal size of the box opening.

[0059] Optionally, the middle anchor chamber module 1 includes a first wall panel 11, a first anchor plate 12, and a first partition plate 13. Two first anchor plates 12 are parallel to each other and spaced apart. Two first wall panels 11 are located on both sides of the two first anchor plates 12 and are connected to the two first anchor plates 12 to form a first hollow structure with openings at both ends. Multiple first partition plates 13 are spaced apart and fixed inside the first hollow structure along the opening direction of the first hollow structure. The preparation of the middle anchor chamber module 1 specifically includes: erecting a first set of splicing frames for the middle anchor chamber module 1; hoisting a first anchor plate 12 into the leveled first set of splicing frames and placing it horizontally on the first set of splicing frames for alignment; after alignment, marking the middle anchor plate 12 on the first anchor plate 12. The assembly line of the first partition 13 of the anchor chamber module 1; according to the assembly line of the first partition 13, multiple first partitions 13 are spaced apart and vertically assembled on the first anchor plate 12, and then spot-welded to fix them; two first wall panels 11 are respectively assembled on both sides of the first anchor plate 12 and abut against the first partition 13, and the first wall panels 11 are spot-welded to the first anchor plate 12 and the first partition 13 respectively; another first anchor plate 12 is hoisted from top to bottom between the two first wall panels 11 and abut against the first partition 13, and the first anchor plate 12 is spot-welded to the first wall panel 11 and the first partition 13 respectively; the spot-welded joints of the assembled middle anchor chamber module 1 are welded to fix it, thus obtaining the middle anchor chamber module 1.

[0060] In this embodiment, as Figure 1 and Figure 3As shown, a first anchor plate 12, a first partition plate 13, and a first wall panel 11 are assembled to form a middle anchor chamber module 1, thereby obtaining the middle anchor chamber module 1 used for assembling and manufacturing steel tower segments. Specifically, firstly, a first set of assembly frames for assembling the middle anchor chamber module 1 is erected, and longitudinal and transverse baselines and measuring points are set on the first set of assembly frames for reference when assembling the first anchor plate 12, the first partition plate 13, and the first wall panel 11. Secondly, a first anchor plate 12 is hoisted into the leveled first set of assembly frames, and the longitudinal baseline of the first anchor plate 12 is aligned with the longitudinal baseline of the first set of assembly frames to ensure the accuracy of the first anchor plate 12 as the basic unit for assembly. Thirdly, after alignment, the assembly line of the first partition plate 13 can be drawn on the first anchor plate 12. Using this assembly line as a reference, the first partition plate 13 is then assembled. Plate 13 is assembled onto the first anchor plate 12 and spot-welded to ensure assembly accuracy. Next, two first wall plates 11 are respectively placed on both sides of the first anchor plate 12 and spot-welded to the first anchor plate 12 and the first partition plate 13 respectively. Then, another first anchor plate 12 is hoisted from top to bottom between the two first wall plates 11 to avoid collision with the first wall plates 11. After hoisting, it is spot-welded to the first wall plate 11 and the first partition plate 13 respectively, forming a first hollow structure as the main structural frame of the middle anchor chamber module 1, while the first partition plate 13 is located inside the first hollow structure to provide support. Finally, the welds at each spot weld of the middle anchor chamber module 1 are welded to ensure the structural stability of the entire middle anchor chamber module 1, resulting in a middle anchor chamber module 1 that meets the manufacturing accuracy requirements.

[0061] It should be noted that, in this embodiment, in order to ensure the stability of the other first anchor plate 12 when it is placed on the first partition plate 13, a temporary support structure can be set between the two first anchor plates 12. For example, a temporary support rod can be set between the two first anchor plates 12.

[0062] Optionally, after the first wall panel 11, the first anchor plate 12 and the first partition plate 13 are assembled in pairs and before spot welding is performed, the assembly method of the steel tower segment further includes: obtaining the first parameter data of the middle anchor chamber module 1 during the assembly process, and determining whether the first parameter data is within the first preset range; if yes, spot welding is performed; if no, correction is performed and the determination is repeated.

[0063] It should be noted that, in this embodiment, the first parameter data includes verticality.

[0064] In this embodiment, after each assembly step of the various plate structures of the middle anchor chamber module 1 is completed, in order to ensure the assembly accuracy, the verticality of the assembled structure can be measured to obtain the first parameter data. Based on the comparison between the first parameter data and the first preset range, it is determined whether the assembled structure meets the accuracy requirements. If the accuracy requirements are met, spot welding is then performed to ensure the assembly accuracy of each assembly step between the various plate structures of the middle anchor chamber module 1.

[0065] In addition, it should be noted that after all the plate structures are assembled, the opening size of the assembled middle anchor chamber module 1 is measured to determine whether the opening size meets the requirements. If the first parameter data such as verticality or opening size does not meet the requirements, it can be corrected to ensure the manufacturing accuracy of the middle anchor chamber module 1 and the steel tower segment.

[0066] Optionally, before the multiple first partitions 13 are spaced apart along the first direction and vertically assembled on the upper surface of the first anchor plate 12 and spot-welded, the assembly method of the steel tower segment further includes: drawing the assembly line of the first anchor box 14 of the middle anchor chamber module 1 on the first anchor plate 12, assembling the first anchor box 14 on the first anchor plate 12 according to the assembly line of the first anchor box 14 and spot-welding it, wherein the first anchor box 14 is located between adjacent first partitions 13.

[0067] In current cable-stayed bridges, after the individual steel tower segments are assembled into a steel tower, anchor pipes need to be inserted into anchor boxes to connect the stay cables and transfer forces between the tower and the main girder. Therefore, each steel tower segment needs to be equipped with an anchor box to meet the connection requirements of the stay cables. In this embodiment, as shown... Figure 1 and Figure 3 As shown, before the first partition plate 13 is assembled onto the first anchor plate 12 via the assembly line and then spot-welded, the assembly line of the first anchor box 14 of the middle anchor chamber module 1 needs to be drawn on the first anchor plate 12. According to the assembly line of the first anchor box 14, the first anchor box 14 can be assembled onto the first anchor plate 12 and then spot-welded. The first anchor box 14 is fixed by the two first anchor plates 12 to ensure the stability of the assembly and fixation of the first anchor box 14.

[0068] Optionally, the side chamber module 2 includes a second partition 21 and a second wall panel 22. Multiple second wall panels 22 are connected sequentially to form a first semi-enclosed structure. Multiple second partitions 21 are parallel to each other, spaced apart and fixed within the first semi-enclosed structure. The preparation of the side chamber module 2 specifically includes: erecting a second set of splicing frames for the side chamber module 2; spaced multiple second partitions 21 and vertically mounted on the second set of splicing frames; sequentially assembling multiple second wall panels 22 onto the second partitions 21 and perpendicularly abutting against the second partitions 21; closing and fixing adjacent two second wall panels 22 together to form a semi-enclosed structure; and fixing the second wall panels 22 to the second partitions 21 to obtain the side chamber module 2.

[0069] In this embodiment, as Figure 1 and Figure 4 As shown, a second partition 21 and a second wall panel 22 are assembled to form a side chamber module 2. Specifically, a second set of assembly frames is erected for assembling the side chamber module 2. Longitudinal and transverse baselines and measuring points are set on the second set of assembly frames, and partition intervals are divided on the second set of assembly frames. Then, according to the partition intervals, the second partition 21 is placed vertically on the second set of assembly frames, and the second partition 21 is fixedly connected to the second set of assembly frames to ensure the accuracy and stability of the subsequent assembly of the second wall panel 22. Finally, according to the longitudinal and transverse baselines on the second set of assembly frames, two second wall panels 22 are sequentially assembled on both sides of the second partition 21 and fixedly connected to the second partition 21. This ensures that the assembly of the second wall panels 22 forms a first semi-enclosed structure to surround the second partition 21, while the second partition 21 provides support for the first semi-enclosed structure, and also avoids interference during the assembly of the second wall panels 22. After the two second wall panels 22 are closed, a side chamber module 2 that meets the manufacturing precision can be obtained.

[0070] It should be noted that, in this embodiment, when assembling the second wall panel 22, it is necessary to measure the shape of the second wall panel 22 and whether the two second wall panels 22 fit together. At the same time, when assembling the two second wall panels 22, it is necessary to check the mutual perpendicular relationship between the second partition 21 and the second wall panel 22. After passing the test, when fixing and connecting them, welding can be used.

[0071] Optionally, after the second partition 21 and the second wall panel 22 are assembled and before the fixed connection is made, the assembly method of the steel tower segment further includes: obtaining the third parameter data of the side chamber module 2 during the assembly process, and determining whether the third parameter data is within the third preset range; if yes, making a fixed connection; if no, correcting and repeating the judgment.

[0072] It should be noted that, in this embodiment, the third parameter data includes verticality.

[0073] In this embodiment, after each assembly step of the various plate structures of the side box chamber module 2 is completed, in order to ensure the assembly accuracy, the verticality of the assembled structure can be measured to obtain the third parameter data. Based on the comparison between the third parameter data and the third preset range, it is determined whether the assembled structure meets the accuracy requirements. If the accuracy requirements are met, it is then fixed to ensure the assembly accuracy of each assembly step between the various plate structures of the side box chamber module 2, thereby ensuring the manufacturing accuracy of the side box chamber module 2 and the steel tower segment.

[0074] In addition, it should be noted that after all the plate structures are assembled, the dimensions of the box opening of the assembled side box module 2 are measured to determine whether the dimensions meet the requirements. If the verticality or the dimensions of the box opening do not meet the requirements, they can be corrected to ensure the manufacturing accuracy of the side box module 2 and the steel tower segment.

[0075] Optionally, obtaining the side anchor chamber module 3 specifically includes: the side anchor chamber module 3 includes a third anchor plate 31, a third inclined wall plate 34, two sets of third partitions 32, and two sets of third wall plates 33. The two third anchor plates 31 are parallel to each other and spaced apart. The two third wall plates 33 of the first set are located on both sides of the two third anchor plates 31 and are connected to the two third anchor plates 31 to form a second hollow structure with openings at both ends. The multiple third partitions 32 of the first set are parallel to each other, spaced apart and fixed in the second hollow structure along the opening direction of the second hollow structure. The two third wall plates 33 of the second set correspond one-to-one with the two third wall plates 33 of the first set. The second set of third partitions 32 are connected to each other and form a second semi-enclosed structure with a third anchor plate 31. Multiple third partitions 32 of the second set are parallel to each other, spaced apart and fixed within the second semi-enclosed structure. Two third inclined wall plates 34 are respectively connected to two third wall plates 33 of the second set, and both are connected to the third partitions 32 of the second set. The preparation of the side anchor chamber module 3 specifically includes: erecting a third set of assembly frames; hoisting a third anchor plate 31 into the leveled third set of assembly frames and placing it horizontally on the third set of assembly frames for alignment; after alignment, marking the assembly lines of the third partitions 32 on the third anchor plate 31; and according to the assembly lines of the third partitions 32, ... The first group of multiple third partitions 32 are spaced apart and vertically assembled onto the third anchor plate 31, and then spot-welded to fix them. Another third anchor plate 31 is assembled onto the first group of multiple third partitions 32, and then spot-welded to the third partitions 32 of the first group perpendicularly. The two third wall panels 33 of the first group are vertically assembled onto both sides of the third anchor plate 31, and then spot-welded to the third anchor plate 31 and the third partitions 32 of the first group, respectively. The side anchor chamber module 3, after being spot-welded, is flipped over. After flipping, the second group of multiple third partitions 32 are spaced apart and vertically assembled onto the third anchor plate away from the third group of the assembly frame. Spot welding is performed on plate 31; the two third wall panels 33 of the second group are vertically assembled on both sides of the third partition 32 of the second group, and spot welded to the third wall panel 33 of the first group and the third partition 32 of the second group respectively; the two third inclined wall panels 34 are assembled on the two third wall panels 33 of the second group, and spot welded to the third partition 32 and the third wall panel 33 of the second group respectively, wherein the ends of the two third inclined wall panels 34 that are away from the third wall panel 33 are inclined towards each other; the spot welded joints of the pre-assembled side anchor chamber module 3 are welded and fixed to obtain the side anchor chamber module 3.

[0076] In this embodiment, as Figure 1 and Figure 5As shown, the third anchor plate 31, third partition plate 32, third wall panel 33, and third inclined wall panel 34 are assembled to form the side anchor chamber module 3. Specifically, a third set of assembly frames with longitudinal and transverse baselines and measuring points is erected. One third anchor plate 31 can be hoisted onto the third set of assembly frames. The placement accuracy of the third anchor plate 31 is ensured by aligning the longitudinal baseline of the third anchor plate 31 with the longitudinal baseline of the third set of assembly frames, thus ensuring the subsequent assembly accuracy. Next, the assembly line of the third partition plate 32 is drawn on the third anchor plate 31. Using this assembly line as a reference, the accuracy of the assembly of the third partition plate 32 onto the third anchor plate 31 is ensured. The third partition plate 32 and the third anchor plate 31 are then spot-welded to ensure structural stability. Then, another third anchor plate 31 is assembled onto the third partition plate 32 and spot-welded to secure it. Two third wall panels 33 are spot-welded to the two sides of each of the two third anchor plates 31. The third anchor plate 31 and the two third wall plates 33 together form the second hollow structure, while the third partition plate 32 is located inside the second hollow structure, providing support for the second hollow structure. At this time, the stability of the assembled structure is satisfied, and it can be flipped over to facilitate the assembly of another third partition plate 32 onto the third anchor plate 31 located above. Two more third wall plates 33 matching the third partition plate 32 are set on both sides of the third anchor plate 31. The two third wall plates 33 of the second group and the third anchor plate 31 form the second semi-enclosed structure, while the third partition plate 32 provides support for the second semi-enclosed structure. At the same time, the third inclined wall plate 34 is set on the third wall plate 33 to facilitate connection with the middle anchor chamber module 1. Finally, the assembled structure is spot-welded to obtain the side anchor chamber module 3, which is convenient for assembly and connection with the middle anchor chamber module 1 and the side box chamber module 2 when assembling the steel tower segments.

[0077] It should be noted that, in this embodiment, in order to ensure the assembly stability of the two third wall panels 33 after flipping, a temporary support structure can be set between the third wall panel 33 and the third anchor plate 31. For example, a temporary diagonal brace structure can be set between the third wall panel 33 and the third anchor plate 31.

[0078] Optionally, before the first group of multiple third partitions 32 of the side anchor chamber module 3 are spaced apart along the first direction and vertically assembled on the upper surface of the third anchor plate 31 and spot-welded, the assembly method of the steel tower segment further includes: drawing the assembly line of the second anchor box 35 of the side anchor chamber module 3 on the third anchor plate 31, assembling the second anchor box 35 on the third anchor plate 31 according to the assembly line of the second anchor box 35 and spot-welding it, wherein the second anchor box 35 is located between adjacent third partitions 32.

[0079] In current cable-stayed bridges, after the individual steel tower segments are assembled into a steel tower, anchor boxes are used to insert anchor pipes to connect the stay cables, thus completing the force transfer between the tower and the main girder. Therefore, each steel tower segment needs to be equipped with an anchor box to meet the connection requirements of the stay cables. In this embodiment, as shown... Figure 1 and Figure 5 As shown, before the third partition 32 is assembled onto the third anchor plate 31 via the assembly line and then spot-welded, the assembly line of the second anchor box 35 of the side anchor chamber module 3 needs to be drawn on the third anchor plate 31. Based on the assembly line of the second anchor box 35, the second anchor box 35 can be assembled onto the third anchor plate 31 and then spot-welded. The second anchor box 35 is fixed by the two third anchor plates 31 to ensure the stability of the assembly and fixation of the second anchor box 35.

[0080] Optionally, after the third anchor plate 31, the third inclined wall plate 34, the two sets of third partition plates 32 and the two sets of third wall plates 33 are assembled in pairs, and before spot welding is performed, the assembly method of the steel tower segment further includes: obtaining the second parameter data of the side anchor chamber module 3 during the assembly process, and determining whether the second parameter data is within the second preset range; if yes, spot welding is performed; if no, correction is performed and the judgment is repeated.

[0081] It should be noted that, in this embodiment, the third parameter data includes verticality.

[0082] In this embodiment, after each assembly step of the various plate structures of the side anchor chamber module 3 is completed, in order to ensure the assembly accuracy, the verticality of the assembled structure can be measured to obtain the second parameter data. Based on the comparison between the second parameter data and the second preset range, it is determined whether the assembled structure meets the accuracy requirements. If the accuracy requirements are met, spot welding is then performed to ensure the assembly accuracy of each assembly step between the various plate structures of the side anchor chamber module 3, thereby ensuring the manufacturing accuracy of the side anchor chamber module 3 and the steel tower segment.

[0083] In addition, it should be noted that after all the plate structures are assembled, the opening size of the assembled side anchor chamber module 3 is measured to determine whether the opening size meets the requirements. If the verticality or the opening size and other third parameters do not meet the requirements, they can be corrected to ensure the manufacturing accuracy of the side anchor chamber module 3 and the steel tower segment.

[0084] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
