Description

Technical Field

[0001] This utility model relates to the field of offshore oil and gas platform protection technology, specifically to a deformation-resistant offshore explosion-proof wall that can greatly improve the load-bearing capacity and deformation capacity of the explosion-proof wall. Background Technology

[0002] In the field of marine engineering, offshore blast walls are the core protective barrier safeguarding offshore platforms, ports, and related facilities, and must effectively resist multiple threats such as explosive impacts and marine environmental erosion. As marine development expands into deep seas and extreme working conditions, the performance requirements for these walls are becoming increasingly stringent, and the challenge of balancing strength and weight has become a key bottleneck restricting their design and application.

[0003] In current technology, the design of offshore blast walls often faces a dilemma. To enhance structural strength and withstand the powerful impact of explosions from offshore oil and gas platforms, conventional practices include increasing wall thickness, using high-strength but high-density materials, or adding numerous rigid support structures. While these designs can enhance the blast wall's impact resistance to some extent, they lead to a dramatic increase in the wall's weight. Excessively heavy blast walls not only place a huge load on the underlying support structures (such as pile foundations and abutments), exacerbating foundation settlement and cracking risks, but also significantly increase the time and cost of offshore operations. On the other hand, using lightweight structures and low-density materials to control weight, while reducing pressure on the support system, makes it difficult to withstand the instantaneous load of an explosion and the long-term cyclical effects of ocean waves. Blast walls are prone to localized deformation, cracking, and even complete collapse, failing to effectively prevent the spread of explosive fragments and exposing marine facilities and personnel to danger. Meanwhile, the unique characteristics of the marine environment—high salt spray, strong corrosion, and complex dynamic loads—further amplify the drawbacks caused by the imbalance between strength and weight. Existing explosion-proof walls frequently require repair and reinforcement due to structural deformation and damage during their service life, resulting in high maintenance costs and difficulty in guaranteeing long-term stable protective performance.

[0004] With the continuous advancement of marine resource development, the demand for blast-resistant walls from offshore oil and gas platforms and port-related industries is constantly growing. These walls require not only high strength to withstand explosive impacts and effectively prevent the spread of disasters, but also controlled weight to reduce reliance on foundation engineering and adaptability to diverse marine site conditions. Therefore, developing a marine blast-resistant wall that achieves an optimal balance between strength and weight, breaking through the performance bottlenecks of existing designs, has become a critical issue urgently needing to be addressed in the field of marine protection engineering. This is crucial to meeting the pressing needs of safe, efficient, and long-term operation of offshore facilities and promoting the upgrading and development of marine engineering protection technologies. Utility Model Content

[0005] To address the aforementioned issues, a deformation-resistant marine explosion-proof wall is provided, which incorporates a support pipe between the two panels, significantly increasing the wall's strength.

[0006] To address the existing technical problems, this utility model provides a deformation-resistant marine explosion-proof wall, comprising a wall module. The wall module comprises two panels and multiple support tubes for increasing the strength of the panels. The two panels are arranged in parallel and spaced apart. The multiple support tubes are arranged at equal intervals between the two panels. The support tubes are provided with reinforcing T-shaped ring ribs (referred to as reinforcing ribs) inside. The outer wall of the support tube contacts the two panels.

[0007] Preferably, the support tube includes a tube body and a plurality of reinforcing ribs, the plurality of reinforcing ribs being spaced apart within the tube body along the axial direction of the tube body.

[0008] Preferably, the contact surfaces of the plurality of support tubes and the two panels are connected by welding.

[0009] Preferably, an elastic limiting block is filled between the outer walls of two adjacent support tubes, and the elastic limiting block contacts the two panels on both sides.

[0010] Preferably, the two sets of panels have the same shape as the outer side of the support tube corresponding to the portion of the support tube, and the panel located between the two support plates is recessed inward.

[0011] The advantages of this utility model compared to the prior art are: The explosion-proof wall of this utility model has multiple support tubes set between the two panels. The support tubes have the function of reinforcing ribs. The mass of the reinforcing ribs is very small, but they greatly increase the moment of inertia of the cross section, which can greatly increase the strength and deformation resistance of the wall.

[0016] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0017] Example 1 This utility model provides a deformation-resistant marine explosion-proof wall, including a wall module 2. The wall module 2 includes two sets of panels 20 and multiple support tubes 21 for increasing the strength of the panels. The two sets of panels 20 are arranged in parallel and spaced apart. The multiple support tubes 21 are arranged at equal intervals between the two panels 20. The support tubes 21 are provided with reinforcing ribs 211. The outer wall of the support tubes 21 is connected to the two panels 20.

[0018] Each support tube 21 includes a tube body 210 and multiple reinforcing ribs 211. The multiple reinforcing ribs 211 are arranged inside the tube body 210. In order to further facilitate processing, the support tube 21 is set as a split structure, and the half tubes are welded together to form an integral support tube 21 structure by seamless welding.

[0019] The reinforcing rib 211 includes a first ring body 2110 and a second ring body 2111. The outer edge of the first ring body 2110 is disposed on the inner wall of the tube body 210, and the outer edge of the second ring body 2111 is disposed on the inner edge of the first ring body 2110. The first ring body 2110 has a plate-like structure, and the second ring body 2111 has a cylindrical structure.

[0020] Multiple support tubes 21 are connected to the contact surfaces of the two panels 20 by welding. Welding the contact surfaces between the support tubes 21 and the two panels 20 makes the wall module 2 a whole.

[0021] An elastic limiting block is filled between the outer walls of two adjacent support tubes 21, and the elastic limiting block contacts the two panels 20 on both sides. The elastic limiting block is preferably a foam block.

[0022] Example 2 In this embodiment, the two sets of panels 20 have the same shape as the outer side of the support tube 21 corresponding to the portion of the support tube 21. The panel 20 located between the two support plates 21 is recessed inward, which increases the contact area between the panel 20 and the support tube 21 on the one hand, and the wavy panel 20 can increase the strength of the panel 20 on the other hand.

[0023] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
