Description

Technical Field

[0001] This utility model relates to the field of bridge structure foundation construction technology, and more specifically, to an operating platform for extending inclined steel pipe piles at sea. Background Technology

[0002] Steel pipe piles are a widely used foundation type in the construction of offshore bridges. During construction, complex and variable geological conditions are often encountered. In the driving of steel pipe piles, situations may arise where the pile top reaches the design elevation, but the penetration depth does not meet design requirements. In such cases, the steel pipe piles must be extended and re-driven.

[0003] However, the offshore construction environment is extremely harsh, with wind, waves, and tides posing significant safety risks to high-altitude and water-adjacent operations. Traditional steel pipe pile splicing operations often require the erection of complex scaffolding or the use of large suspended platforms, resulting in long installation cycles, poor stability, significant susceptibility to tidal influences, and the inability to quickly recycle the equipment. This not only seriously threatens the lives of workers but also restricts the overall construction progress and quality.

[0004] Therefore, there is an urgent need in this field for a dedicated operating platform that is structurally stable, easy to install and disassemble, adaptable to harsh marine environments, and can be quickly deployed and reused to ensure the safety and efficiency of steel pipe pile splicing operations. Utility Model Content

[0005] This utility model aims to solve the problems of unstable structure, inconvenient installation and disassembly, and inability to adapt to harsh marine environments in existing operating platforms used for extending inclined steel pipe piles at sea.

[0006] To address the aforementioned problems, this utility model provides an operating platform for extending inclined steel pipe piles at sea, comprising two bottom beam supports arranged parallel to each other on both sides of the steel pipe pile; multiple sets of tie rod fastening systems are provided on the steel pipe pile, and the two bottom beam supports are fixedly connected to the steel pipe pile through the multiple sets of tie rod fastening systems; a platform panel system is provided on the bottom beam supports; and a safety protection system is provided around the platform panel system.

[0007] This utility model provides an operating platform for extending inclined steel pipe piles at sea, which, compared with the prior art, has the following beneficial effects, but is not limited to: The function of the bottom beam support in this utility model is to support the main beam: the tensioning system, through the finely rolled threaded steel bars passing through the steel pipe pile and the nuts at both ends, firmly clamps the two bottom beam supports to both sides of the steel pipe pile like a clamp. The platform panel system provides a working surface, offering a safe and flat standing and working space for construction personnel, and the safety protection system prevents personnel from falling.

[0008] This utility model ensures the stability of the platform by combining tensioning with welding of precision-rolled threaded steel; it enables rapid installation, disassembly, and deployment through modular design and lifting lugs; and it effectively resists the effects of tides through panel openings, making it a special operating platform particularly suitable for harsh marine construction environments.

[0009] This utility model boasts strong structural stability and high safety: It utilizes a four-set high-strength, precision-rolled threaded steel tie-down system to firmly clamp the bottom beam support onto the steel pipe piles, forming a stable load-bearing foundation. Subsequent reinforcement with welded steel plates provides double protection, ensuring the platform's overall stability in windy and wavy environments and greatly safeguarding the safety of workers.

[0010] This utility model is easy to install and dismantle, and quick to deploy: the platform adopts a modular design, and the bottom beam and panel can be hoisted separately, allowing for rapid on-site assembly. When it is necessary to change the working surface, only a small number of reinforcing steel plates need to be cut and the nuts loosened, and the entire structure can be hoisted and transported using the lifting lugs, greatly improving construction efficiency and shortening the construction period.

[0011] This invention is adapted to the marine environment: the moisture-proof holes on the platform panel effectively reduce the upward thrust of water flow on the panel during high tide, preventing the platform from shifting or capsizing due to water pressure, thus enhancing its adaptability in tidal environments. The anti-corrosion treatment of the overall structure also extends the platform's service life.

[0012] This utility model is economical and practical: It mainly uses conventional steel and standard parts, which has low manufacturing cost and can be reused repeatedly, thus having good economic benefits.

[0013] Furthermore, reinforcing steel plates are provided between the bottom beam support and the steel pipe pile.

[0014] Furthermore, the tensioning system includes a precision-rolled threaded steel bar, a thickened nut, a square steel washer, and a U-shaped steel washer; the precision-rolled threaded steel bar is installed through the steel pipe pile, and both ends of the precision-rolled threaded steel bar are fastened to the two bottom beam supports through the thickened nut, the square steel washer, and the U-shaped steel washer.

[0015] Furthermore, the precision-rolled threaded steel bar is a φ20 HRB500 grade steel bar, and the square steel shim is a 100×100×10mm square steel shim.

[0016] Furthermore, the platform panel system includes multiple panel distribution beams fixed to the bottom beam support and perforated panels laid on the panel distribution beams; the perforated panels are provided with evenly distributed moisture-proof holes.

[0017] Furthermore, the panel distribution beam is made of [10 channel steel, and the perforated panel is made of 4mm thick steel plate.

[0018] Furthermore, the safety protection system is a railing, which includes uprights made of [10 channel steel and horizontal bars made of φ48×3mm round tubes.

[0019] Furthermore, the reinforcing steel sheet is made of Q235 steel plate and is welded between the bottom beam support and the steel pipe pile.

[0020] Furthermore, the reinforcing steel sheet has dimensions of 400mm × 10mm.

[0021] Furthermore, the bottom beam support and / or platform panel system are provided with lifting lugs, which are made of Q235 steel. Attached Figure Description

[0031] See Figures 1-5 An operating platform for extending inclined steel pipe piles at sea according to an embodiment of the present invention includes a bottom beam support 1, wherein there are two bottom beam supports 1, which are arranged in parallel on both sides of the steel pipe pile. Multiple sets of tie-fastening systems are installed on the steel pipe piles, and the two bottom beam supports 1 are fixedly connected to the steel pipe piles through multiple sets of tie-fastening systems; The bottom beam support 1 is equipped with a platform panel system; the platform panel system is equipped with a safety protection system around its perimeter.

[0032] The function of the bottom beam support 1 in this utility model is as a load-bearing main beam: as the core load-bearing structure of the entire operating platform, it is responsible for bearing all loads from the platform panel, construction materials, workers, and equipment. It provides anchoring points and reaction support for the tensioning system, transferring and distributing the clamping force generated by the tensioning system to the contact surface with the steel pipe piles. As the foundation for the installation of the platform panel system, its levelness and firmness directly determine the stability and safety of the upper working plane.

[0033] The tensioning system uses finely threaded steel bars penetrating the steel pipe piles and nuts at both ends to firmly clamp the two bottom beam supports to both sides of the steel pipe piles like "clamps." It provides initial stability: before welding reinforcement, this system is the only way for the platform to be independently fixed to the steel pipe piles, bearing all loads in the early stages of construction, including its own weight and wind loads. The finely threaded steel bars can adapt to the inclination angle of the steel pipe piles, and the force is adjusted using components such as U-shaped washers to ensure that the clamping force is perpendicular to the pile surface, achieving effective fixation.

[0034] The platform panel system provides a working surface: offering construction personnel a safe and level standing and working space for operations such as measuring, cutting, and welding steel pipe piles. It distributes loads: the concentrated loads of personnel and equipment are dispersed and transferred to the bottom beam supports via the panel and distribution beams. It resists environmental impacts: the moisture-proof holes on the panel are a key design feature, designed to drain tides and reduce the jacking force and buoyancy of the platform during high tide.

[0035] Safety protection system prevents falls: A physical barrier is formed around the work area to effectively prevent workers from falling from the platform edge due to slips or external forces. Provides psychological safety: Provides psychological support to workers operating at heights or near water, allowing them to focus more on their tasks.

[0036] The installation process of this utility model is as follows: First, the bottom beam support 1 is installed. Two bottom beam supports 1 made of [20 channel steel are placed parallel to each other on both sides of the design elevation position of the steel pipe pile 11. Then, they are initially fixed using four sets of tie-fastening systems. Each set of tie-fastening systems includes a φ20×2700mm precision-rolled threaded steel bar 7, four thickened nuts 2, a 100×100×10mm square steel washer 4, and a U-shaped steel washer 3. The precision-rolled threaded steel bar 7 passes through the hole pre-drilled in the steel pipe pile 11, and the square steel washer 4 and the U-shaped steel washer 3 are successively fitted on both ends. Then, the thickened nuts 2 are screwed on and pre-tightened. By adjusting the nuts, the levelness of the two bottom beam supports 1 can be initially ensured.

[0037] Next, the platform panel system is hoisted. The platform panel system consists of multiple [10 channel steel panel distribution beams 9 and two 4mm thick perforated panels 5 laid on the distribution beams. The panel distribution beams 9 are pre-welded to the perforated panels 5 as a whole. Using four lifting lugs 6 welded to the perforated panels 5, the entire platform panel system is hoisted and placed onto the bottom beam support 1. After positioning, the panel distribution beams 9 are welded and fixed to the bottom beam support 1 to form a stable working surface.

[0038] Then, structural reinforcement was carried out. After the platform panel system was installed, multiple 400×10mm Q235 steel plates were used as reinforcing steel plates 8. One end of the plates was welded to the bottom beam support 1, and the other end was welded to the pile wall of the steel pipe pile 11, thereby rigidly connecting the platform to the steel pipe pile 11 and greatly enhancing the overall structure's resistance to wind and waves.

[0039] Finally, the safety protection system is installed. Around the platform panel system, railings 10, consisting of [10 channel steel uprights and φ48×3mm round tube crossbars, are installed to form a complete safety protection system.

[0040] At this point, the operating platform is installed, and workers can be transferred to the platform via a suspended basket to carry out operations such as welding and extending the steel pipe piles.

[0041] The transfer process of this utility model is as follows: When the construction of this work surface is completed and it is necessary to hoist the platform to the next work surface, the process is the reverse of the installation.

[0042] First, attach the hoisting rope to the lug 6 on the bottom beam support 1 to apply slight stress to the crane.

[0043] Then, the reinforcing steel plate 8 connecting the bottom beam support 1 and the steel pipe pile 11 is cut off using an oxy-fuel cutting tool.

[0044] Next, loosen the thickened nut 2 located at the U-shaped steel washer 3 in the four-group tie-fastening system.

[0045] Finally, the crane will lift the entire operating platform and transfer it to the new working face of the steel pipe pile 11. The above installation steps can be repeated for reuse.

[0046] This utility model ensures the stability of the platform by combining tensioning with welding of precision-rolled threaded steel; it enables rapid installation, disassembly, and deployment through modular design and lifting lugs; and it effectively resists the effects of tides through panel openings, making it a special operating platform particularly suitable for harsh marine construction environments.

[0047] This utility model boasts strong structural stability and high safety: It utilizes a four-set high-strength, precision-rolled threaded steel tie-down system to firmly clamp the bottom beam support onto the steel pipe piles, forming a stable load-bearing foundation. Subsequent reinforcement with welded steel plates provides double protection, ensuring the platform's overall stability in windy and wavy environments and greatly safeguarding the safety of workers.

[0048] This utility model is easy to install and dismantle, and quick to deploy: the platform adopts a modular design, and the bottom beam and panel can be hoisted separately, allowing for rapid on-site assembly. When it is necessary to change the working surface, only a small number of reinforcing steel plates need to be cut and the nuts loosened, and the entire structure can be hoisted and transported using the lifting lugs, greatly improving construction efficiency and shortening the construction period.

[0049] This invention is adapted to the marine environment: the moisture-proof holes on the platform panel effectively reduce the upward thrust of water flow on the panel during high tide, preventing the platform from shifting or capsizing due to water pressure, thus enhancing its adaptability in tidal environments. The anti-corrosion treatment of the overall structure also extends the platform's service life.

[0050] This utility model is economical and practical: It mainly uses conventional steel and standard parts, which has low manufacturing cost and can be reused repeatedly, thus having good economic benefits.

[0051] Furthermore, a reinforcing steel plate 8 is provided between the bottom beam support 1 and the steel pipe pile.

[0052] The reinforcing steel plate upgrades the connection between the operating platform and the steel pipe pile from a mechanical connection to a rigid connection, achieving double fixation and greatly enhancing overall stability. The tensioned threaded steel system is essentially a detachable "clamp," belonging to the mechanical connection category. The reinforcing steel plate, however, is welded so that one end is fused to the bottom beam support, and the other end is fused to the pile wall of the steel pipe pile, thus firmly "locking" the platform and the steel pipe pile together, forming a rigid whole. It resists overturning moments: When workers operate at the edge of the platform or when there is wind, the platform will generate an overturning moment that tends to cause the bottom beam support to rotate around the threaded steel. The threaded steel mainly bears tensile forces, while the welded reinforcing steel plate can very effectively resist this shear and torsional stress. It prevents slippage: Although the threaded nut provides a large preload, there is still a risk of slight slippage under long-term vibration and impact. Welding fundamentally eliminates the possibility of slippage in any direction. It works in conjunction with the threaded steel system to jointly bear all dynamic and static loads from above the platform, making the stress distribution more reasonable and the safety reserve higher.

[0053] Furthermore, the tensioning system includes a precision-rolled threaded steel bar 7, a thickened nut 2, a square steel washer 4, and a U-shaped steel washer 3; the precision-rolled threaded steel bar 7 is installed through the steel pipe pile, and both ends of the precision-rolled threaded steel bar 7 are fastened to the two bottom beam supports 1 through the thickened nut 2, the square steel washer 4, and the U-shaped steel washer 3.

[0054] The tensioning system provides a high-strength, adjustable, and detachable active clamping force, symmetrically and firmly locking the two bottom beam supports to both sides of the steel pipe pile like a "clamp," establishing a stable and reliable load-bearing foundation for the entire platform. The precision-rolled threaded steel bar 7, acting as a tie rod, is the core component bearing the tension force. It penetrates the steel pipe pile, connecting the two bottom beam supports. The thickened nut 2, acting as a force-applying unit, generates a significant preload tension on the precision-rolled threaded steel bar by tightening the nut.

[0055] The square steel shim 4 serves to distribute pressure. It disperses the enormous concentrated force generated by the nut onto the flange surface of the channel steel at the bottom beam support, preventing excessive local pressure that could deform or damage the channel steel and ensuring effective and uniform transmission of clamping force. The U-shaped steel shim 3 adjusts the stress surface. On inclined piles, the threaded steel bar is not perpendicular to the pile surface. If a flat shim is used directly, the shim and the pile body will have line contact or small-area contact, resulting in extremely poor stress and easily damaging the anti-corrosion layer of the pile wall or even causing local depressions in the pile body. The arc-shaped surface of the U-shaped shim can fit well with the arc-shaped outer wall of the steel pipe pile, forming an "adaptive" stress support, distributing the clamping force evenly over a larger area of ​​the pile wall, while ensuring that the tensile axis of the threaded steel bar is approximately perpendicular to the pile body, achieving the best clamping effect and protecting the steel pipe pile itself.

[0056] Furthermore, the precision-rolled threaded steel bar 7 is a φ20 HRB500 grade steel bar, and the square steel shim 4 is a 100×100×10mm square steel shim.

[0057] As the core load-bearing component of the tension fastening system, the high tensile strength of the threaded steel bar is used to withstand the huge preload generated by tightening the nut and all additional loads during platform use, such as personnel, equipment, and wind loads, to ensure that the entire clamping system does not break or elongate excessively when under stress.

[0058] The core function of the square steel washer is to effectively distribute and transfer the concentrated force applied by the nut to a larger area of ​​the bottom beam support, preventing excessive local stress from damaging the bottom beam support and ensuring that the clamping force can be applied evenly and stably.

[0059] Furthermore, the platform panel system includes multiple panel distribution beams 9 fixed to the bottom beam support 1 and perforated panels 5 laid on the panel distribution beams 9; the perforated panels 5 are provided with evenly distributed moisture-proof holes.

[0060] Construct a sturdy, non-slip working platform that can effectively resist the effects of tides, and safely and effectively transfer the upper load to the lower support structure.

[0061] As a secondary beam above the bottom beam support, the panel distribution beam 9's main function is to collect and redistribute concentrated or uniformly distributed loads from the perforated panel, then transfer them to the bottom beam support in a more rational stress distribution manner. Enhancing overall stiffness: Welding the distribution beam to the bottom beam forms a robust planar truss or grid structure, significantly improving the overall stiffness and stability of the platform panel system in both horizontal and vertical directions, preventing excessive deformation or vibration of the panel during use.

[0062] The perforated panel 5 provides the primary working surface: this is the surface where construction workers directly stand, walk, and place tools and equipment, representing the platform's most basic function. The evenly distributed moisture-proof holes on the panel are a key design feature specifically for the marine tidal environment. Their mechanism is as follows: Eliminating buoyancy and jacking forces: During high tide, seawater submerges the lower part of the platform. Without these holes, the platform panel would act like a "piston" or "lid," subjected to enormous upward jacking forces (buoyancy) and horizontal impact forces from the seawater. These forces would be transmitted to the tie rod system and welds, posing a significant risk of capsizing. The moisture-proof holes allow seawater to freely pass through the panel, greatly reducing the pressure difference between the upper and lower surfaces, thus effectively eliminating most of the jacking and buoyancy forces. Rapid drainage: After low tide or splashing, water accumulated on the platform can be quickly drained through these holes, keeping the working surface relatively dry, non-slip, and safe.

[0063] Furthermore, the panel distribution beam 9 is made of [10 channel steel, and the perforated panel 5 is made of 4mm thick steel plate.

[0064] [10 Channel steel has a much higher moment of inertia than simple square or flat steel. This means that it undergoes less bending deformation under the same load. The planar flanges of the channel steel provide an ideal interface for welding. It can be easily welded to the flanges of the bottom beam support [with large area and high quality] to form a strong rigid connection.]

[0065] A 4mm thick steel plate is sufficient to withstand the loads from construction workers, tools, and loose materials without permanent deformation or damage from foot traffic. Weight is controllable: Using thicker steel plates, such as 6mm or 8mm, would proportionally increase weight, leading to difficulties in hoisting, increased load on the substructure, and higher costs. 4mm is a proven, economically optimal thickness that meets construction safety requirements. Easy to cut and drill holes: A 4mm thick steel plate is easily cut and perforated using methods such as plasma cutting, laser cutting, or stamping to create uniform moisture-proof holes, resulting in low processing costs and high efficiency.

[0066] Furthermore, the safety protection system is a railing 10, which includes uprights made of [10 channel steel and horizontal bars made of φ48×3mm round tubes.

[0067] [10. Channel steel uprights provide primary support and anchorage: The uprights are the "legs" of the railing, firmly welded to the framework of the platform panel system, typically the panel distribution beams or bottom beams, transferring the load of the entire railing to the main structure. They withstand horizontal impact forces: When people accidentally lean against or collide with the railing, the uprights need to withstand the resulting horizontal forces and bending moments to prevent the entire railing system from overturning or failing. The function of the φ48×3mm round tube crossbars: Forming the main protective surface: The crossbars are the "arms" of the railing, connecting the uprights to form one or more continuous protective barriers between them, directly preventing people from crossing the platform edge. Distributing loads: When impacted, the crossbars distribute the impact force and transfer it to multiple uprights, preventing the force from concentrating on a single upright.]

[0068] Furthermore, the reinforcing steel plate 8 is made of Q235 steel plate and is welded between the bottom beam support 1 and the steel pipe pile.

[0069] The Q235 steel plate reinforcing steel plates provide a rigid connection to resist overturning and sliding: the tensioned, finely rolled threaded steel system is essentially a detachable "clamp," relying primarily on the static friction generated by the enormous preload to resist platform slippage and rotation. The reinforcing steel plates are welded together, with one end fused to the bottom beam support and the other end fused to the pile wall of the steel pipe pile, thus firmly "locking" the platform and the steel pipe pile together to form a rigid whole. This connection method can directly transmit shear force and bending moment, fundamentally eliminating the possibility of sliding and overturning in any direction. As a crucial safety redundancy: this is the core value of the reinforcing steel plates. They act as the second line of defense in the entire fixing system.

[0070] Furthermore, the reinforcing steel sheet 8 has dimensions of 400mm × 10mm.

[0071] To ensure sufficient connection strength and rigidity, the welding process is optimized, materials are minimized, and platform disassembly is convenient. A 400mm weld length provides ample weld length to ensure reliable force transmission, achieve optimal lever arm effect, and effectively resist overturning. A 10mm thickness provides excellent shear and tear resistance, matching the strength of the base material, namely the bottom beam and pile wall.

[0072] Furthermore, the bottom beam support 1 and / or platform panel system are provided with lifting lugs 6, which are made of Q235 steel.

[0073] Lifting lug 6 provides a standardized, high-strength, and absolutely reliable lifting connection point for the operating platform, enabling rapid, safe, and efficient overall platform transfer and installation. The lifting lug is a standard component specifically designed for lifting; its shape, welds, and internal reinforcement structure are calculated and designed to withstand specific dynamic loads. When the platform needs to be transferred to the next working surface, the crane hook can directly connect to the lifting lug on the bottom beam and panel, significantly shortening the lifting preparation time. Supporting modular construction: This design is key to the platform's function as an independent and complete tool. It allows the platform to move quickly between multiple steel pipe piles like a large "toolbox," directly contributing to the core objective of "accelerating construction progress and shortening the construction period."

[0074] Although 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.
