Description

Technical Field

[0001] This invention belongs to the field of steel cylinder vibratory hammer technology, and particularly relates to an assembled resonant beam assembly for a steel cylinder vibratory hammer assembly and its assembly method. Background Technology

[0002] The rapid island-building technology using large-diameter steel cylinders is widely used in numerous projects due to its advantages such as short island-building time and low construction cost. During the construction of large-diameter steel cylinders, the steel cylinder is held in place by a steel cylinder clamp, and multiple vibratory hammers, through a resonant beam system, vibrate synchronously. The enormous excitation force overcomes the side friction and end resistance between the steel cylinder and the soil, causing the steel cylinder to sink at a uniform speed.

[0003] The resonant beam system is the core structure that enables multiple vibratory hammers to vibrate synchronously and sink steel cylinders at a uniform speed. To adapt to steel cylinders of different diameters, a prefabricated resonant beam system has been developed. For example, patent CN115781615A discloses an assembled resonant beam and its assembly method for a large-diameter steel cylinder vibratory hammer assembly. It manufactures the vibratory beam as a standard connector and the connecting beam as a series of standard connectors. Based on the diameter of the steel cylinder, appropriately sized connecting beams are selected and alternately assembled with the vibratory beam to form a complete resonant beam. However, the vibratory beam and connecting beam are assembled using flange plates and bolts. This connection structure is difficult to meet the shear resistance requirements during vertical vibration. To improve shear resistance, a large number of friction bolts are required for connection, utilizing friction to achieve shear resistance. These friction bolts almost cover the contact surface between the vibratory beam and the connecting beam, resulting in a huge workload for assembly. Furthermore, a large number of shear keys need to be additionally set between the vibratory beam and the connecting beam, leading to structural complexity and further increasing the assembly workload. In addition, during assembly, separate jigs are required for the vibratory beam and connecting beam to provide positioning and support, making the positioning and assembly operations cumbersome and inefficient.

[0004] Therefore, how to provide a prefabricated resonant beam assembly with strong shear resistance, simple structure, and easy assembly is a technical problem that urgently needs to be solved. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides an assembled resonant beam assembly for a steel cylinder vibratory hammer assembly and its assembly method. This assembled resonant beam assembly has sufficient shear resistance, requires no additional shear keys, and has a simple structure that is easy to assemble.

[0006] This invention provides an assembled resonant beam assembly for a steel cylinder vibratory hammer assembly, comprising: Multiple vibrating beams are arranged at equal intervals along a circumference, with the central axis of the circumference set vertically. An assembled connecting beam is assembled between two adjacent vibrating beams and forms a ring around the perimeter of each vibrating beam. It includes a replaceable beam module and two fixed beam modules. The two fixed beam modules are respectively fixed to the opposite sides of the two adjacent vibrating beams. A first connecting member is provided on the side of the fixed beam module away from the vibrating beam. The first connecting member has a first trapezoidal corrugated structure with alternating concave and convex shapes along the vertical direction, and the first trapezoidal corrugated structure penetrates the first connecting member radially along the circumference. Second connecting members are provided on both sides of the replaceable beam module. The second connecting members have a second trapezoidal corrugated structure that can be inserted into the first trapezoidal corrugated structure, and the second trapezoidal corrugated structure penetrates the second connecting member radially along the circumference. The replaceable beam module is inserted between the two fixed beam modules through the second connecting members on both sides and the corresponding first connecting members.

[0007] In some embodiments, the first connecting member is a first trapezoidal corrugated plate arranged vertically. The fixed beam module also includes two first end caps arranged vertically opposite each other. The two first end caps are respectively fixed to the vertical ends of the first trapezoidal corrugated plate. A first central beam plate is provided within the space enclosed by the two first end caps and the first trapezoidal corrugated plate. The first central beam plate is respectively fixed to the two first end caps and the first trapezoidal corrugated plate. The ends of the two first end caps away from the first trapezoidal corrugated plate and the ends of the first central beam plate away from the first trapezoidal corrugated plate are both fixed to the vibrating... The moving beam; the second connecting member is a second trapezoidal corrugated plate arranged vertically, which is matched with the first trapezoidal corrugated plate. The replaceable beam module also includes two second end plates arranged opposite each other in the vertical direction. The two ends of the two second end plates are respectively fixed to the two second trapezoidal corrugated plates, and the two second end plates are respectively arranged close to the two vertical ends of the second trapezoidal corrugated plates. A second middle beam plate is provided in the space enclosed by the two second end plates and the two second trapezoidal corrugated plates. The second middle beam plate is respectively fixed to the two second end plates and the two second trapezoidal corrugated plates.

[0008] In some embodiments, a reinforcing plate is also fixed between the second central beam plate and the two second end caps.

[0009] In some embodiments, the second end cap is an isosceles trapezoid with its upper base facing the center of the circumference, and its two sides are respectively fixed to two second trapezoidal corrugated plates.

[0010] In some embodiments, the base angles of the isosceles trapezoid are 75° to 89°.

[0011] In some embodiments, the second middle beam is arranged in a transverse direction with the extension direction of the base of the isosceles trapezoid formed by the second end cap plate as the transverse direction, and the reinforcing plate is perpendicular to the second middle beam plate.

[0012] In some embodiments, the first central beam plate has a first weight-reducing hole, the second central beam plate has a second weight-reducing hole, and the reinforcing plate has a third weight-reducing hole.

[0013] In some embodiments, the fastening connector is a connecting bolt, the first trapezoidal corrugated plate has a first bolt hole for the connecting bolt to pass through, and the second trapezoidal corrugated plate has a second bolt hole for the connecting bolt to pass through.

[0014] In some embodiments, the first bolt holes are only formed in the recesses or protrusions of the first trapezoidal corrugated plate, and each recess or protrusion has only one row of first bolt holes. The second bolt holes are formed on the second trapezoidal corrugated plate at positions opposite to the first bolt holes of the first trapezoidal corrugated plate.

[0015] The present invention also provides an assembly method for a prefabricated resonant beam assembly for a steel cylinder vibratory hammer assembly, comprising the following steps: S1. Weld fixed beam modules to both ends of each vibrating beam; S2. Place the vibration beam brackets one by one according to the design position of each vibration beam. Place each vibration beam with the fixed beam module welded at both ends on the vibration beam bracket one by one, and adjust the position and angle of each vibration beam. After adjusting, fix each vibration beam on the corresponding vibration beam bracket. S3. With the radial outer end of the circumference formed by each vibrating beam as the front, hoist the replaceable beam modules one by one to the front of the center line of two adjacent vibrating beams, so that the two second connecting parts of the replaceable beam module are respectively aligned with the first connecting parts of the two fixed beam modules connected to the opposite sides of the two adjacent vibrating beams, and insert the rear end of the second trapezoidal corrugated structure of the second connecting part into the front end of the first trapezoidal corrugated structure of the corresponding first connecting part, so as to complete the support and preliminary positioning of each replaceable beam module. S4. Push each replaceable beam module radially backward between the two fixed beam modules. After pushing it into place, temporarily fix the replaceable beam module and its two adjacent fixed beam modules. S5. Check the position of each replaceable beam module and fine-tune the position of any replaceable beam modules that are not in place. After ensuring that each replaceable beam module is in place, use fastening connectors to fasten the second connector of each replaceable beam module to its corresponding first connector, thereby replacing the temporary fixing measures between each replaceable beam module and the corresponding fixed beam module.

[0016] Compared with the prior art, the advantages and beneficial effects of the present invention are as follows: 1. The assembled resonant beam assembly for steel cylinder vibratory hammer assembly provided by the present invention adopts an assembled connecting beam. In the assembled connecting beam, fixed beam modules are set at both ends and fixedly connected to adjacent vibratory beams, and a replaceable beam module is set in the middle and detachably connected to the two fixed beam modules. By changing the replaceable beam modules of different specifications, the diameter of the assembled resonant beam assembly can be adjusted. It has good versatility and effectively saves resources and costs. 2. The prefabricated resonant beam assembly for a steel cylinder vibratory hammer assembly provided by the present invention, wherein in the prefabricated connecting beam, the fixed beam module is connected to the second connecting piece of the replaceable beam module having a second trapezoidal corrugated structure through a first connecting piece having a first trapezoidal corrugated structure, forming a trapezoidal corrugated concave-convex socket connection structure. This connection structure utilizes a multi-faceted fitting limiting method to disperse and bear shear loads, and has shear resistance similar to that of welding under high-frequency vibration loads. It does not require additional shear resistance structures, is simple and reliable, and significantly reduces the number of parts and assembly work. Moreover, this connection structure breaks through the conventional connection method of traditional connecting beams that can only be fastened for shear resistance by welding or a large number of friction bolts, taking into account both the shear resistance and simplicity of the prefabricated structure, and has engineering application value. 3. The assembled resonant beam assembly for steel cylinder vibratory hammer assembly provided by the present invention has a trapezoidal corrugated concave-convex socket connection structure between the fixed beam module and the replaceable beam module in the assembled connecting beam. While achieving shear resistance, it can effectively position and support the replaceable beam module. During assembly, there is no need to set up a separate jig for positioning and supporting the replaceable beam module, which greatly simplifies the assembly process and the required tooling, and helps to shorten the assembly cycle and reduce the assembly cost. 4. The assembled resonant beam assembly for steel cylinder vibratory hammer assembly provided by the present invention can be reused by separating the replaceable beam module and the fixed beam module. When reused, only the detachable connection operation of the replaceable beam module and the fixed beam module is required, without any fixing operation, which is convenient for reuse. Moreover, it is easy to store after disassembly. 5. The assembly method of the assembled resonant beam group for the steel cylinder vibratory hammer group provided by the present invention only uses vibratory beam brackets to support and position the vibratory beam and its connected fixed beam modules, while the replaceable beam modules achieve support and positioning by inserting with the fixed beam modules on both sides, which greatly reduces the use of brackets, reduces assembly costs, simplifies the assembly process, and improves assembly efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] As attached Figures 1-4 As shown, in an illustrative embodiment of the assembled resonant beam assembly for a steel cylinder vibratory hammer assembly of the present invention, the assembled resonant beam assembly for the steel cylinder vibratory hammer assembly includes multiple vibrating beams 1 and assembled connecting beams 2.

[0024] Vibrating beam 1 is used to transmit the vibration of the vibrating hammer; its upper part is used to connect the vibrating hammer, and its lower part is used to connect the steel cylinder clamp. For example... Figure 1 As shown, in this embodiment, multiple vibrating beams 1 are arranged at equal intervals along a circumference, with the central axis of the circumference set vertically, so as to be installed on the top of a vertical steel cylinder by a steel cylinder clamp. It should be noted that the number of vibrating beams 1 is set according to the number of vibrating hammers, the position is set according to the position of the vibrating hammers, and the diameter of the circumference formed by the multiple vibrating beams 1 is determined according to the diameter of the steel cylinder to be vibrated.

[0025] The prefabricated connecting beam 2 is used to connect each vibrating beam 1, so that each vibrating beam 1 vibrates synchronously. For example... Figures 1-4As shown, in this embodiment, the prefabricated connecting beam 2 is assembled between two adjacent vibrating beams 1 and forms a ring around each vibrating beam 1. It includes a replaceable beam module 22 and two fixed beam modules 21. The two fixed beam modules 21 are respectively fixed to the opposite sides of the two adjacent vibrating beams 1. A first connecting member is provided on the side of the fixed beam module 21 away from the vibrating beam 1. The first connecting member has a first trapezoidal corrugated structure with alternating concave and convex shapes along the vertical direction. The first trapezoidal corrugated structure passes through the first connecting member radially along the circumference. Second connecting members are provided on both sides of the replaceable beam module 22. The second connecting member has a second trapezoidal corrugated structure that can be inserted and engaged with the first trapezoidal corrugated structure. The second trapezoidal corrugated structure passes through the second connecting member radially along the circumference. The replaceable beam module 22 is inserted between the two fixed beam modules 21 by the second connecting members on both sides and the corresponding first connecting members. The second connecting members and the corresponding first connecting members are detachably connected by fastening connectors 23. In use, by pre-fixing two fixed beam modules 21 to the opposite sides of adjacent vibrating beams 1, and relying on the socket fit between the first trapezoidal corrugated structure of the first connecting piece of the fixed beam module 21 and the second trapezoidal corrugated structure of the second connecting pieces at both ends of the replaceable beam module 22, the replacement beam module 22 can be quickly inserted and positioned between the two fixed beam modules 21. Then, the fastening connector 23 achieves a secure connection between the replaceable beam module 22 and the two fixed beam modules 21, thereby rigidly connecting each vibrating beam 1 and the prefabricated connecting beam 2 into a single unit, forming a prefabricated resonant beam assembly. It should be noted that the replaceable beam module 22 can be manufactured in a series of parts with different widths (specifically, the dimension in the circumferential tangential direction). By selecting replaceable beam modules 22 of different widths, the diameter of the prefabricated resonant beam assembly can be adjusted to adapt to the construction needs of steel cylinders of different diameters. It should also be noted that the fixed beam module 21 and the vibrating beam 1 are connected by welding to ensure a stable connection between the fixed beam module 21 and the vibrating beam 1.

[0026] The aforementioned assembled resonant beam assembly for the steel cylinder vibratory hammer group adopts an assembled connecting beam 2. In this assembled connecting beam 2, fixed beam modules 21 are set at both ends and fixedly connected to the adjacent vibrating beam 1, and a replaceable beam module 22 is set in the middle and detachably connected to the two fixed beam modules 21. By replacing the replaceable beam modules 22 of different specifications, the diameter of the assembled resonant beam assembly can be adjusted. It has good versatility and effectively saves resources and costs. Meanwhile, in the prefabricated resonant beam assembly used for the steel cylinder vibratory hammer assembly, the fixed beam module 21, through a first connector with a first trapezoidal corrugated structure, cooperates with the second connector with a second trapezoidal corrugated structure of the replaceable beam module 22 to form a trapezoidal corrugated concave-convex socket connection structure. This connection structure utilizes a multi-faceted fitting limiting method to disperse and bear shear loads. Under high-frequency vibration loads, it has shear resistance similar to that of welding, eliminating the need for additional shear resistance structures. The structure is simple and reliable, significantly reducing the number of parts and assembly work. Moreover, this connection structure breaks through the conventional connection method of traditional connecting beams that can only be secured by welding or a large number of friction bolts for shear resistance. It takes into account both the shear resistance and simplicity of prefabricated structures and has engineering application value. Furthermore, in the aforementioned prefabricated resonant beam assembly for steel cylinder vibratory hammers, the trapezoidal corrugated socket connection structure between the fixed beam module 21 and the replaceable beam module 22 in the prefabricated connecting beam 2 not only provides shear resistance but also effectively positions and supports the replaceable beam module 22. During assembly, there is no need to separately erect a jig for positioning and supporting the replaceable beam module 22, greatly simplifying the assembly process and reducing the required tooling, thus shortening the assembly cycle and reducing assembly costs. In addition, the aforementioned prefabricated resonant beam assembly for steel cylinder vibratory hammers can be reused by separating the replaceable beam module 22 from the fixed beam module 21. During reuse, only the detachable connection between the replaceable beam module 22 and the fixed beam module 21 needs to be performed, without any fixing work, facilitating reuse and easy storage after disassembly.

[0027] like Figure 3As shown, the first connecting member is a first trapezoidal corrugated plate 211 arranged vertically. The fixed beam module 21 also includes two first end plates 212 arranged opposite each other in the vertical direction. The two first end plates 212 are respectively fixed to the two vertical ends of the first trapezoidal corrugated plate 211. A first middle beam plate 213 is provided in the space enclosed by the two first end plates 212 and the first trapezoidal corrugated plate 211. The first middle beam plate 213 is respectively fixed to the two first end plates 212 and the first trapezoidal corrugated plate 211. The ends of the two first end plates 212 away from the first trapezoidal corrugated plate 211 and the ends of the first middle beam plate 213 away from the first trapezoidal corrugated plate 211 are both fixed to the vibrating beam 1. Using a first trapezoidal corrugated plate 211 as the first connecting member, in conjunction with the first end caps 212 located at the upper and lower ends and the first central beam plate 213 located inside, a hollow box-type fixed beam module 21 can be formed. This fixed beam module 21 has sufficient load-bearing capacity and the advantages of light weight and low cost. Furthermore, the first trapezoidal corrugated plate 211, the first end caps 212, and the first central beam plate 213 can all be made from existing sheet materials, facilitating processing and manufacturing. It should be noted that, as... Figure 3 As shown, multiple first central beam plates 213 can be provided to meet the structural bearing capacity requirements of the fixed beam module 21. Preferably, the first central beam plates 213 are made of I-beams to ensure the structural strength of the fixed beam module 21. It should also be noted that the connection between the first end cap plate 212 and the first trapezoidal corrugated plate 211, as well as the connection between the first central beam plate 213 and the first end cap plate 212 and the first trapezoidal corrugated plate 211, can all be achieved by welding.

[0028] Furthermore, such as Figure 3 As shown, the first middle beam plate 213 has a first weight reduction hole 2131, which is beneficial to further reduce the weight of the fixed beam module 21.

[0029] like Figures 4-6As shown, the second connecting member is a second trapezoidal corrugated plate 221 arranged vertically. The second trapezoidal corrugated plate 221 is socketed and matched with the first trapezoidal corrugated plate 211. The replaceable beam module 22 also includes two second end plates 222 arranged vertically opposite each other. The two ends of the two second end plates 222 are respectively fixed to the two second trapezoidal corrugated plates 221, and the two second end plates 222 are respectively arranged close to the two vertical ends of the second trapezoidal corrugated plates 221. A second middle beam plate 223 is provided in the space enclosed by the two second end plates 222 and the two second trapezoidal corrugated plates 221. The second middle beam plate 223 is respectively fixed to the two second end plates 222 and the two second trapezoidal corrugated plates 221. Using a second trapezoidal corrugated plate 221 as the second connecting member, in conjunction with the second end caps 222 located at the upper and lower ends and the second central beam plate 223 located inside, a replaceable beam module 22 with a hollow box structure can be formed. This replaceable beam module 22 has both sufficient load-bearing capacity and the advantages of light weight and low cost. Furthermore, the second trapezoidal corrugated plate 221, the second end caps 222, and the second central beam plate 223 can all be made from existing sheet materials, facilitating processing and manufacturing. It should be noted that, as Figure 6 As shown, multiple second central beam plates 223 can be provided to meet the structural bearing capacity requirements of the replaceable beam module 22. Preferably, the second central beam plates 223 are made of I-beams to ensure the structural strength of the replaceable beam module 22. It should also be noted that the connection between the second end plate 222 and the second trapezoidal corrugated plate 221, as well as the connection between the second central beam plate 223 and the second end plate 222 and the second trapezoidal corrugated plate 221, can all be achieved by welding.

[0030] Furthermore, such as Figure 4 and Figure 6 As shown, a reinforcing plate 224 is also fixedly connected between the second middle beam plate 223 and the two second end caps 222. The reinforcing plate 224 further strengthens the internal structural strength of the hollow replaceable beam module 22, ensuring that the replaceable beam module 22 has sufficient structural load-bearing capacity. Preferably, as... Figure 5 As shown, the reinforcing plate 224 is connected to the middle of the second middle beam plate 223. It should be noted that the reinforcing plate 224 is connected to the second middle beam plate 223 and the second end sealing plate 222 by welding.

[0031] Furthermore, such as Figure 5As shown, the second end cap 222 is an isosceles trapezoid with its upper base facing the center of the circumference, and its two sides are fixed to two second trapezoidal corrugated plates 221 respectively. Setting the second end cap 222 as an isosceles trapezoid makes the replaceable beam module 22 have a front-larger, rear-smaller structure in the radial direction of the circumference, facilitating insertion between the two fixed beam modules 21. Preferably, the base angle α of the isosceles trapezoid is 75°~89°. Setting the base angle α of the isosceles trapezoid formed by the second end cap 222 within the range of 75°~89° allows the two second trapezoidal corrugated plates 221 connected to the second end cap 222 to be closer to parallel, making the second trapezoidal corrugated plates 221 of the replaceable beam module 22 and the first trapezoidal corrugated plates 211 of the fixed beam module 21 as closely as possible to be butt-jointed, which is beneficial for improving structural stability.

[0032] Furthermore, such as Figure 6 As shown, with the extension direction of the base of the isosceles trapezoid formed by the second end cap 222 as the transverse direction, the second middle beam plate 223 is arranged transversely, and the reinforcing plate 224 is perpendicular to the second middle beam plate 223. Since the second end cap 222 and the two second trapezoidal corrugated plates 221 all bear tensile forces in the transverse direction, the transverse arrangement of the second middle beam plate 223 is beneficial to improving the structural strength of the replaceable beam module 22. At the same time, the arrangement of the reinforcing plate 224 perpendicular to the second middle beam plate 223 can structurally reinforce the replaceable beam module 22 in a direction perpendicular to the transverse direction.

[0033] Furthermore, such as Figure 4 As shown, the second middle beam plate 223 has a second weight reduction hole 2231, and the reinforcing plate 224 has a third weight reduction hole 2241, which helps to further reduce the weight of the replaceable beam module 22 and facilitates hoisting.

[0034] like Figures 2-4 As shown, the fastening connector 23 is a connecting bolt. The first trapezoidal corrugated plate 211 has a first bolt hole 2111 for the connecting bolt to pass through, and the second trapezoidal corrugated plate 221 has a second bolt hole 2211 for the connecting bolt to pass through. In the trapezoidal corrugated concave-convex socket connection structure formed by the first connector with the first trapezoidal corrugated structure and the second connector with the second trapezoidal corrugated structure used in this embodiment of the invention, since the connection structure itself has shear resistance similar to that of welding, only a simple connecting bolt is needed as the fastening connector 23 to achieve a tight connection between the first connector and the second connector, ensuring the robustness of the connection between the replaceable beam module 22 and the fixed beam module 21.

[0035] Preferred, such as Figures 2-4As shown, the first bolt holes 2111 are only provided in the recesses or protrusions of the first trapezoidal corrugated plate 211, and each recess or protrusion has only one row of first bolt holes 2111. The second bolt holes 2211 are provided on the second trapezoidal corrugated plate 221 at positions opposite to the first bolt holes 2111 of the first trapezoidal corrugated plate 211. This arrangement ensures a firm connection while minimizing the number of connecting bolts, thus reducing assembly workload.

[0036] The assembly method for the prefabricated resonant beam assembly used in the steel cylinder vibratory hammer assembly includes the following steps: S1. Weld fixed beam modules 21 to both ends of each vibrating beam 1; S2. Place the vibration beam 1 brackets one by one according to the design position of each vibration beam 1. Place each vibration beam 1 with the fixed beam module 21 welded at both ends on the vibration beam 1 brackets one by one, and adjust the position and angle of each vibration beam 1. After adjusting, fix each vibration beam 1 on the corresponding vibration beam 1 bracket. S3. With the radial outer end of the circumference formed by each vibration beam 1 as the front, the replaceable beam modules 22 are hoisted one by one to the front of the center line of two adjacent vibration beams 1, so that the two second connecting parts of the replaceable beam module 22 are respectively aligned with the first connecting parts of the two fixed beam modules 21 connected to the opposite sides of the two adjacent vibration beams 1, and the rear end of the second trapezoidal corrugated structure of the second connecting part is inserted into the front end of the first trapezoidal corrugated structure of the corresponding first connecting part, so as to complete the support and preliminary positioning of each replaceable beam module 22. S4. Push each replaceable beam module 22 radially backward between the two fixed beam modules 21. After pushing it into place, temporarily fix the replaceable beam module 22 and its two adjacent fixed beam modules 21. S5. Check the position of each replaceable beam module 22, and fine-tune the position of any replaceable beam modules 22 that are not in place. After ensuring that each replaceable beam module 22 is in place, use the fastening connector 23 to fasten the second connector of each replaceable beam module 22 to its corresponding first connector, so as to replace the temporary fixing measures between each replaceable beam module 22 and the corresponding fixed beam module 21.

[0037] The assembly method for the prefabricated resonant beam assembly used in this steel cylinder vibratory hammer group only requires the installation of a vibratory beam 1 bracket to support and position the vibratory beam 1 and its connected fixed beam module 21. The replaceable beam module 22 is supported and positioned by inserting into the fixed beam modules 21 on both sides, which greatly reduces the use of brackets, lowers assembly costs, simplifies the assembly process, and improves assembly efficiency. Furthermore, the above-mentioned assembly method for the prefabricated resonant beam assembly used in this steel cylinder vibratory hammer group only involves welding during the initial connection of the fixed beam module 21 and the vibratory beam 1. Subsequent initial connections of the replaceable beam module 22 to the fixed beam module 21, or connections during reuse, do not require welding operations. This avoids environmental pollution caused by on-site welding and also avoids cumulative welding deviations caused by multiple welding points and multiple welders during reuse.

[0038] Preferably, in step S4, when the replaceable beam module 22 is pushed radially back until the second bolt hole 2211 on the second trapezoidal corrugated plate 221 of the replaceable beam module 22 aligns with the first bolt hole 2111 on the first trapezoidal corrugated plate 211 of the fixed beam module 21, it is determined that the replaceable beam module 22 has been pushed into place. Temporary limiting pins are inserted into the second bolt hole 2211 and the corresponding first bolt hole 2111 to temporarily fix the replaceable beam module 22 and the fixed beam module 21.
