Description

Technical Field

[0001] This invention belongs to the field of bridge construction technology and relates to a support structure and transportation method suitable for the assembly and transportation of individual components on both sides of a dike. Background Technology

[0002] During bridge construction, the construction of the piers near the riverbank requires simultaneous transportation and construction of composite beams on both the water and land surfaces. However, complex terrain structures such as embankments, ditches, or river tributaries on the land along the riverbank can hinder the transportation and construction of composite beams in these areas. For example, the Cao'e River embankment and its revetment structure, as well as the Huan Tang Nanhe River along the river, are located between the main and auxiliary piers involved in bridge construction, making the transportation conditions for this part of the bridge extremely complex. Assembling composite beams is impossible in the embankment and shallow river areas, and transporting the assembled composite beams to these areas is also difficult. While constructing foundation platforms in the embankment and shallow river areas sufficient to support the composite beams and related construction equipment would allow for the installation of the composite beams on land, it would significantly increase construction costs and time. Summary of the Invention

[0003] The purpose of this invention is to provide a modular assembly and transport support system suitable for both sides of a dike, which solves the technical problem in the prior art where there are complex terrain structures on the bank that affect the transportation and construction of composite beams. In such cases, it is difficult to assemble, transport and install the corresponding composite beams in complex terrain structures, which greatly increases the construction difficulty, cost and time.

[0004] The aforementioned support structure for assembling and transporting a bridge on both sides of a dike includes a horizontally arranged sliding track, a support structure, and an assembly platform. The sliding track is set through the support structure and crosses a complex terrain structure. The sliding track is set along the same line as the bridge. The complex terrain structure includes the dike. The bottom of the sliding track is at the same elevation as the top surface of the dike. One end of the sliding track extends to the bank of the water area where the main pier is located, while the other end crosses the dike and is equipped with the assembly platform.

[0005] Preferably, the complex terrain structure also includes a shallow river located on the side of the embankment away from the main pier. The sliding track is divided into a first track segment and a second track segment. The sliding track that crosses the embankment is the first track segment. One end of the first track segment is located between the embankment and the shallow river. The assembly platform also includes a platform one and a platform two. Platform one is located at the end of the first track segment. The bottom of the first track segment is at the same elevation as the top surface of platform one. One end of the second track segment extends to platform one, while the other end crosses the shallow river and is connected to platform two.

[0006] Preferably, an auxiliary pier is provided between the embankment and the shallow river, the first section of the track is provided between the auxiliary pier and the main pier, and the platform is provided on the side of the auxiliary pier closer to the main pier; the supporting structure supporting the first section of the track is a ground support, which includes steel columns and enlarged foundations, and the top surface of the steel columns is at the same elevation as the top of the embankment.

[0007] Preferably, the top surface of the embankment is filled with an inverted trapezoidal crossing channel, which includes a retaining wall between sliding tracks, a slope end retaining wall, and a slope side retaining wall. The retaining wall between sliding tracks is located between the sliding tracks on both sides and its top height is lower than the sliding tracks. The slope end retaining wall is located outside the sliding tracks and its top height is higher than the sliding tracks. The slope side retaining wall is a sloping structure located outside the slope end retaining wall, with the higher side of the slope side retaining wall attached to the side of the slope end retaining wall. The slope side retaining wall and the retaining wall between sliding tracks are arranged along the curb of the edge of the top surface of the embankment, and the slope end retaining wall is arranged along the sliding tracks.

[0008] Preferably, the steel columns between the main pier and the embankment are set on an enlarged foundation one. The enlarged foundation one and the steel columns thereon are located on the concrete slope protection, sheet piles and riprap of the embankment on one side of the embankment. The enlarged foundation one is formed by direct casting. The steel columns between the embankment and the platform one are set on an enlarged foundation two. A portion of the enlarged foundation two and the steel columns thereon are located on the embankment slope on the other side of the embankment. The embankment slope is partially excavated into a stepped shape for casting the enlarged foundation two.

[0009] Preferably, the platform includes a transverse distribution beam, a longitudinal distribution beam, and a steel plate. The transverse distribution beam and the longitudinal distribution beam are perpendicularly and fixedly connected to and fixed to the top of the steel column. The steel plate is erected on the transverse distribution beam and the longitudinal distribution beam.

[0010] Preferably, an auxiliary pier two is provided on the side of the shallow river away from the embankment, the second track segment is provided between the first auxiliary pier and the second auxiliary pier, and the second platform is provided on the side of the second auxiliary pier closer to the main pier; the supporting structure supporting the second track segment is a strip foundation, and the top surface of the second platform and the top surface of the strip foundation are both flush with the ground.

[0011] Preferably, the shallow river within the coverage area of ​​the second track segment is filled in, and a pre-reserved culvert is buried in the filled part of the shallow river. The strip foundation is set in the ground on both sides of the shallow river and in the filled part; the second platform is set by taking concrete hardening measures on the ground.

[0012] Preferably, a sliding drive device is provided on the sliding track. The sliding drive device includes a sliding cylinder and a slider. One end of the sliding cylinder is bolted to the track groove of the sliding track through a connecting seat, and the other end is welded to the slider through a connecting seat. The slider slides along the track groove, and a load-bearing structure of a load-bearing composite beam is installed on the slider.

[0013] The present invention also provides a method for transporting and assembling a single structure using the aforementioned scaffolding suitable for transporting and assembling components on both sides of a dike, comprising the following steps:

[0014] Step 1: Construct a cross-sectional assembly and transportation support structure;

[0015] Step 2: Construct an inverted trapezoidal crossing channel on the top surface of the embankment;

[0016] Step 3: Treat the foundation of the assembly site where the assembly platform will be set up, and then erect the assembly platform.

[0017] Step 4: Transport the loose components of the composite beam to the assembly site by land.

[0018] Step 5: Install the sliding drive device on the sliding track;

[0019] Step 6: Use a crawler crane to assemble the loose components on the assembly platform to obtain the composite beam;

[0020] Step 7: Slide the assembled composite beam to the lifting position, and remove the composite beam from the side span from the sliding track to realize the lifting and installation of the composite beam;

[0021] Step 8: After completing the installation of all the composite beams on the side spans and the tensioning of the stay cables, disassemble the assembled and transported support frame.

[0022] This invention has the following advantages: The modular assembly and transport support system configured in this solution allows for the assembly of composite beams at the assembly platform. Platform one, corresponding to the first segment of the track crossing the embankment, is positioned flush with the top of the embankment, as it crosses the top. The composite beams are assembled on this platform using a crawler crane. This facilitates the lifting of individual components to higher ground and makes assembly on platform one more convenient and safer than lifting the entire composite beam. Furthermore, this modular assembly and transport support system effectively overcomes the embankment's obstruction to the installation of composite beams and allows for beam retrieval from the first track segment at any point on the bridge above the embankment. Additionally, this portion of the modular assembly and transport support system utilizes an inverted trapezoidal crossing passage to ensure normal vehicle passage during the sliding of non-steel beams.

[0023] For the shallow river area on the other side of the dike, this solution utilizes a second track segment and a second platform to assemble the composite beams on the second platform. The beams are then transported to any location within this area via the second track segment, facilitating the removal of beams from any point for composite beam installation and overcoming the obstruction posed by the shallow river. Simultaneously, by filling the shallow river section and embedding pre-installed culverts within the filled area, the solution avoids obstructing the river's flow while simultaneously enabling the installation of the track's strip foundation. This sliding track is positioned flush with the ground, and the second platform is directly constructed with concrete. This approach ensures sufficient load-bearing capacity for both the second track segment and the second platform while effectively reducing construction work and saving construction time.

[0034] The following detailed description of the embodiments, with reference to the accompanying drawings, will further illustrate the specific implementation of the present invention, in order to help those skilled in the art to have a more complete, accurate, and in-depth understanding of the inventive concept and technical solution of the present invention.

[0035] like Figure 1-9 As shown, the present invention discloses a support structure suitable for the assembly and transportation of materials on both sides of a dike, comprising a horizontally arranged sliding track, a support structure, and an assembly platform. The sliding track is set through the support structure and crosses a complex terrain structure. The sliding track is set along the same line as the bridge. The complex terrain structure includes the dike 7. The bottom of the sliding track is at the same elevation as the top surface of the dike 7. One end of the sliding track extends to the bank of the water area where the main pier is located, while the other end crosses the dike 7 and is provided with the assembly platform.

[0036] The complex terrain structure also includes a shallow river located on the side of the embankment 7 away from the main pier. The sliding track is divided into a first track segment 1 and a second track segment 3. The sliding track crossing the embankment 7 is the first track segment 1, with one end located between the embankment 7 and the shallow river. The assembly platform also includes a first platform 2 and a second platform 4. The first platform 2 is located at the end of the first track segment 1, and the bottom of the first track segment 1 is at the same elevation as the top surface of the first platform 2. One end of the second track segment 3 extends to the first platform 2, while the other end crosses the shallow river and is connected to the second platform 4.

[0037] Track segment 1 and platform 2: An auxiliary pier 5 is provided between the embankment 7 and the shallow river. Track segment 1 is located between the auxiliary pier 5 and the main pier. Platform 2 is located on the side of the auxiliary pier 5 closer to the main pier. The supporting structure for track segment 1 is a ground-supported bracket, which includes a steel column 10 and an enlarged foundation. The top surface of the steel column 10 is at the same elevation as the top of the embankment.

[0038] An inverted trapezoidal crossing passage is constructed on the top surface of Embankment 7 to ensure normal vehicle passage during the non-steel beam sliding period. The inverted trapezoidal crossing passage includes retaining walls between the sliding tracks, slope end retaining walls, and slope side retaining walls. The retaining walls between the sliding tracks are located between the two sliding tracks and their top height is lower than the sliding tracks. The slope end retaining walls are located outside the sliding tracks and their top height is higher than the sliding tracks. The slope side retaining walls are sloping structures located outside the slope end retaining walls, with the higher side of the slope side retaining walls abutting the side of the slope end retaining walls and having the same height. Both the slope side retaining walls and the sliding track retaining walls are arranged along the curb strip at the edge of the top surface of Embankment 7. The slope end retaining walls are arranged along the sliding tracks, and all retaining walls are 30cm wide and constructed with C30 concrete.

[0039] The steel columns 10 between the main pier and the embankment 7 are set on the enlarged foundation 19. The enlarged foundation 19 and the steel columns 10 thereon are situated on the concrete slope protection, sheet piles, and riprap of the embankment 7 on one side of the embankment 7. The enlarged foundation 19 is formed by direct casting, and the corresponding concrete cushion layer is also formed by direct casting. A concrete slope is cast on one side of the embankment 7 where the enlarged foundation 19 is located, and anchor bars are installed on the concrete slope. The steel columns 10 between the embankment 7 and the platform 12 are set on the enlarged foundation 211. A portion of the enlarged foundation 211 and the steel columns 10 thereon are situated on the slope of the embankment 7 on the other side of the embankment 7. The slope of the embankment 7 is partially excavated into a stepped shape for casting the enlarged foundation 211, which includes backfill soil.

[0040] The platform 2 includes a transverse distribution beam 21, a longitudinal distribution beam 22, and a steel plate 23. The transverse distribution beam 21 and the longitudinal distribution beam 22 are perpendicularly and fixedly connected to the top of the steel column 10. The steel plate 23 is erected on the transverse distribution beam 21 and the longitudinal distribution beam 22.

[0041] The first track segment 1 is made of 2HM588*300mm, placed horizontally, and is 50m long. The transverse bridge spacing of the track centerline is 31.15m. The transverse distribution beam 21 is made of HM588*300mm, and the longitudinal distribution beam 22 is made of I-beam 22a. A 6mm steel plate 23 is laid on it. The assembly platform is 29.95m long and 12m wide.

[0042] Track segment 3 and platform 2 4: An auxiliary pier 2 6 is set on the side of the shallow river away from the embankment 7. Track segment 3 is set between auxiliary pier 1 5 and auxiliary pier 2 6. Platform 2 4 is set on the side of auxiliary pier 2 6 closer to the main pier. The supporting structure for track segment 3 is a strip foundation 8. The top surfaces of platform 2 4 and strip foundation 8 are both flush with the ground.

[0043] The shallow river within the coverage area of ​​the second section 3 of the track is filled in, and a pre-installed culvert is buried in the filled section to ensure a water resistance rate of less than or equal to 46.9%. The strip foundation 8 is set in the ground on both sides of the shallow river and in the filled section. The second platform 4 is set by hardening the ground with concrete, with its top surface flush with the ground, and its dimensions are 33.5m * 10m * 0.3m.

[0044] The second track segment 3 is horizontally set on the strip foundation 8. The top surface of the strip foundation 8 is flush with the ground, with a length of 41m and a total height of 0.5m. The width is 1m for the 0-0.2m height range and 1.4m for the 0.2-0.5m height range. The second track segment 3 is made of 2HM588*300mm, with a length of 40m and a transverse bridge spacing of 31.15m between the track centerlines.

[0045] A sliding drive device is provided on the sliding track. The sliding drive device includes a sliding cylinder 13 and a slider 12. One end of the sliding cylinder 13 is bolted to the track groove of the sliding track through a connecting seat, and the other end is welded to the slider 12 through a connecting seat. The slider 12 slides along the track groove, and a load-bearing structure of a load-bearing composite beam is installed on the slider 12.

[0046] Based on the above-mentioned applicable modular and integrated transport supports for both sides of the dike 7, the present invention also provides an integrated transport method, comprising the following steps:

[0047] Step 1: Construct a cross-sectional assembly and transportation support structure.

[0048] The steps include: driving anchor bars on the concrete slope of the embankment 7 facing the main pier, directly pouring an enlarged foundation 9 on the concrete slope protection, sheet piles and riprap of the embankment 7 on that side, and installing steel columns 10 on the enlarged foundation 9.

[0049] On the other side of the dike 7, a stepped section is excavated on the slope of the dike 7 for the pouring of the enlarged foundation 2 11. After backfilling the enlarged foundation 2 11, steel columns 10 are installed on the enlarged foundation 2 11. The top surface of the steel columns 10 is at the same elevation as the top of the dike.

[0050] The first section of the rail is laid based on the steel column 10. The bottom of the first section of the rail is at the same elevation as the top surface of the embankment 7. One end of the first section of the rail extends to the shore of the water where the main pier is located, while the other end crosses the embankment 7 and extends to the auxiliary pier 5.

[0051] Before expanding the foundation, the bearing capacity of the foundation must be tested. If the bearing capacity does not meet the design requirements, replacement, driving pine piles, or other reinforcement measures must be taken. After the foundation construction is completed, a truck crane is used to install the columns, tracks, distribution beams, and other structures from bottom to top.

[0052] The shallow river within the coverage area of ​​the second section 3 of the track will be filled in, and a reserved water passage culvert will be buried in the filled part of the shallow river to ensure that the water resistance rate is less than or equal to 46.9%.

[0053] Strip foundations 8 are installed on the ground on both sides of the shallow river and in the filled area. The top surface of the strip foundations 8 is flush with the ground. The second track segment 3 is laid horizontally on the strip foundations 8. One end of the second track segment 3 extends to the end of the first track segment 1, while the other end crosses the shallow river to the auxiliary pier 6.

[0054] Before construction of strip foundation 8, the bearing capacity of the foundation must be tested. If the bearing capacity does not meet the design requirements, replacement, driving pine piles or other reinforcement measures must be taken.

[0055] Step 2: Construct an inverted trapezoidal crossing passage on the top surface of Embankment 7 to ensure normal vehicle passage during the non-steel beam slippage.

[0056] This step includes: arranging retaining walls at the end of the slope along the sliding track, using C30 concrete, with each retaining wall being 30cm wide and 63.8cm high, higher than the height of the sliding track. Along the curb of the top surface of the embankment 7, arranging retaining walls on the side slope and retaining walls between the sliding tracks, the retaining walls between the sliding tracks having a height of 51.8cm, lower than the height of the sliding track.

[0057] The slope end retaining wall is located outside the sliding track. The slope side retaining wall is a sloping structure. The higher side of the slope side retaining wall is attached to the side of the slope end retaining wall and is at the same height as the slope end retaining wall. The slope side retaining wall extends outward by 600cm and its lower side extends to the top surface of the embankment 7.

[0058] Step 3: Treat the foundation of the assembly site where the assembly platform is set up, and then erect the assembly platform.

[0059] This step includes: setting up platform 2 on the side of the auxiliary pier 5 near the main pier, with a length of 12m along the bridge direction; the top surface elevation of platform 2 is at the same level as the bottom of the sliding track, which facilitates the installation of the bridge inspection vehicle track.

[0060] An enlarged foundation is set on the side of the auxiliary pier 5 near the main pier, and a steel column 10 is set on it. The transverse distribution beam 21 and longitudinal distribution beam 22 that make up the platform 2 are installed on the steel column 10. Then, steel plates 23 are erected on the transverse distribution beam 21 and longitudinal distribution beam 22 to complete the construction of the platform 2.

[0061] Before expanding the foundation, the bearing capacity of the foundation must be tested. If the bearing capacity does not meet the design requirements, replacement, driving pine piles, or other reinforcement measures must be taken. After the foundation construction is completed, a truck crane is used to install the columns, tracks, distribution beams, and other structures from bottom to top.

[0062] Platform 24 is constructed by hardening the ground with concrete, and the top surface of platform 24 is flush with the ground.

[0063] Step 4: Transport the individual components of the composite beam to the assembly site by land.

[0064] When installing the composite beams on the land portion of the side span between the main pier and auxiliary pier 5, the individual components of the composite beams are transported to the assembly site of platform 2; when installing the composite beams between auxiliary pier 5 and auxiliary pier 6, the individual components of the composite beams are transported to the assembly site of platform 4.

[0065] Step 5: Install the sliding drive device on the sliding track.

[0066] When preparing for sliding construction, sliding drive devices should be installed on the first track segment 1 and the second track segment 3. One end of the corresponding sliding cylinder 13 is fixed to the end of the sliding track with the assembly platform via a connecting seat. The connecting seat is bolted to the track groove at that location and also bolted to one end of the sliding cylinder 13. The other end of the sliding cylinder 13 is welded to the slider 12, which slides along the corresponding track groove. A load-bearing structure consisting of a load-bearing composite beam is installed on the slider 12.

[0067] Step 6: Use a crawler crane to assemble the components on the assembly platform to obtain the composite beam.

[0068] This step includes ensuring that the surfaces of the composite beam components are free of debris and easily detachable parts during construction. Additional protective measures are also implemented on the assembly platform.

[0069] It provides control measurement points and line markers for the positioning of composite beam components, enabling precise positioning.

[0070] According to the process plan, adjust the weld gaps and misalignment between the composite beam components, and comprehensively control the alignment of adjacent composite beam segments and the joint bevel dimensions to meet the welding process requirements on site.

[0071] The assembly frame should be erected according to the process requirements, requiring high precision, small deformation, high rigidity, and reusability. The frame alignment should be set according to the actual cross slope, longitudinal slope, and pre-camber of the composite beam. Assembly can only proceed after the total station has been used to measure and check for errors.

[0072] When composite beam components arrive on site, they should be placed on stable sleepers and classified according to their numbers and installation sequence. During assembly, collisions and heavy impacts should be avoided as much as possible. Attention should be paid to the protection of the surface anti-corrosion primer and intermediate paint, and any damaged or exposed outer surfaces should be promptly derusted and recoated.

[0073] The composite beams are assembled using a 1+1 modular assembly method. This involves assembling individual components into a composite beam. In a 1+1 modular assembly, after assembling the first land-based composite beam, this beam serves as the parent beam, and subsequent composite beams are then matched and assembled with it, ensuring accurate matching and installation between the two composite beams. Subsequent modular assembly processes also use the next composite beam obtained from the previous 1+1 modular assembly as the parent beam for assembling the next composite beam segment.

[0074] After assembly, the overall dimensions and position of the composite beam must be measured and inspected. The splicing accuracy and overall dimensions must meet the design requirements, and the height difference must not exceed 2mm.

[0075] Weld quality is inspected, and welds that do not meet quality standards are dealt with promptly.

[0076] Step 7: Slide the assembled composite beam to the lifting position, and remove the composite beam from the side span from the sliding track to achieve the lifting and installation of the composite beam.

[0077] When installing the composite beam between the main pier and auxiliary pier 5, the composite beam is assembled at platform 2, and then the assembled composite beam is slid into place using a sliding drive device. The side span girder crane lifts the beam from the first section 1 of the track, and then completes the lifting and installation of the corresponding composite beam.

[0078] When the installation of the composite beam reaches the segment position of the sliding track, the corresponding composite beam is assembled on the platform 2 corresponding to the first segment 1 of the track. Then, the composite beam is disassembled and the parts are transported to the second platform 4. The composite beam is restored and reassembled as the mother beam. After that, the restored mother beam is slid to the lifting position through the second segment 2 of the track for lifting and installation.

[0079] When installing the composite beam between auxiliary pier 1 (5) and auxiliary pier 2 (6), the composite beam is assembled at platform 2 (4). Then, the assembled composite beam is slid into place using a sliding drive device. The side span girder crane lifts the beam from the second section (3) of the track, and then the lifting and installation of the corresponding composite beam is completed.

[0080] The composite beam of the last segment of the side span is cut according to the actual measured segment length, and then lifted and installed.

[0081] Step 8: After completing the installation of all the composite beams on the side spans and the tensioning of the stay cables, dismantle the assembled and transported support frame. This step utilizes an 80t truck crane in conjunction with manual labor, dismantling the frame sequentially from top to bottom, and then transporting it to the rear site.

[0082] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
