Description

Technical Field

[0001] This utility model relates to the field of bridge engineering anti-ship collision technology, and in particular to an anti-ship collision device for bridge piers using energy-absorbing fenders and steel-coated composite materials. Background Technology

[0002] In recent years, with the rapid development of water transportation, the number of bridges crossing rivers has been increasing, and accidents involving ship collisions to bridge piers have also occurred frequently. These accidents not only cause huge economic losses but also seriously threaten the lives of people on ships and vehicles on bridges. Therefore, the research and application of anti-ship collision devices for bridge piers has become an important topic in the field of bridge engineering.

[0003] Currently, while commonly used floating flexible energy-absorbing bridge pier anti-collision devices can protect bridge piers and reduce damage from ship collisions to a certain extent, many problems still need to be solved:

[0004] 1. Construction difficulties: Existing devices are usually designed as a single unit, which makes the installation process complicated and the construction efficiency low. The construction difficulty is further increased, especially in deep water or complex water flow conditions.

[0005] 2. High maintenance costs: When the equipment is damaged by a ship collision, it often needs to be replaced as a whole, resulting in high maintenance costs and a long replacement cycle, which affects the normal use of the bridge.

[0006] 3. Risk of secondary damage: While absorbing impact energy, traditional fenders may cause secondary damage to the bridge piers themselves, reducing the protective effect and even aggravating the damage to the bridge piers.

[0007] 4. Insufficient durability: Due to long-term exposure to water, existing equipment is susceptible to corrosion, resulting in a shortened service life and increased maintenance frequency and costs.

[0008] In summary, existing bridge pier anti-ship collision devices have significant shortcomings in terms of ease of construction, economy, protective performance, and durability. Utility Model Content

[0009] To address the aforementioned issues, this utility model provides a steel-coated composite material anti-ship collision device for bridge piers that employs energy-absorbing fenders. This device offers better economic efficiency, is easier to construct and replace, and provides superior protection for the bridge piers.

[0010] The technical solution adopted in this utility model is as follows:

[0011] A steel-coated composite material bridge pier anti-ship collision device with energy-absorbing fenders is disclosed. The device includes a front box section, side box sections, and flange connectors. One side of the front box section is connected to two side box sections via flange connectors, and the other side protrudes outward. The side box sections include several side box segments, which are connected to each other via flange connectors. After the front box section and the side box sections are connected, a rectangular anti-collision body is formed and fitted onto the bridge pier. The inner sides of the front box section and each side box segment are provided with energy-absorbing fenders that contact the bridge pier.

[0012] Furthermore, the horizontal cross-section of the front box section is triangular, and the front box section is spliced ​​together from several side box sections into a long strip; the front box section and each side box section are box structures, with several reinforcing ribs arranged circumferentially on the inner wall of the box, and the inside of the box is filled with high-polymer foam energy-absorbing material, and the outer surface of the box is coated with an anti-corrosion composite material layer.

[0013] Furthermore, the flange connector includes a front segment flange connector, a side segment flange connector, and connecting bolts; the front segment flange connector is welded to the front housing segment to form an integral unit, and the side segment flange connector is welded to the side housing segment to form an integral unit; the side segment flange connectors are connected to the front segment flange connectors, and to each other, by a number of connecting bolts.

[0014] Furthermore, the flange connector has a manhole at the bolt connection between the side segment flange connector and the front segment flange connector or the other side segment flange connector. After the front box section and the side box section are connected, the manhole is closed by a cover plate.

[0015] Furthermore, the energy-absorbing fender includes an energy-absorbing fender base, an energy-absorbing anti-blocking block, and a rubber pad; the energy-absorbing fender base is a V-shaped seat structure, one side of which is bolted to the front box section and each side box section, and the other side of which is fitted with an energy-absorbing anti-blocking block; a rubber pad is fitted on the side of the energy-absorbing anti-blocking block away from the energy-absorbing fender base.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] To address the problems of inconvenient construction, high maintenance costs, risk of secondary damage, and insufficient durability of existing bridge pier anti-ship collision devices, this embodiment provides a steel-coated composite material bridge pier anti-ship collision device employing energy-absorbing fenders. For example... Figure 1 and Figure 2 As shown, the steel-coated composite material anti-ship collision device for bridge piers using energy-absorbing fenders includes a front box section 1, a side box section, and a flange connector 3; the specific positional relationship, connection method, and function of each component are as follows:

[0034] like Figure 1 and Figure 2 As shown, the front box section 1 is arranged on the front of the pier 7, with one side connected to the two side box sections via flange connectors 3, and the other side protruding outward to form a protective structure. Figure 1 and Figure 2 As shown, the side box sections are arranged on both sides of the pier 7, and are spliced ​​together from two side box sections 2. The two side box sections 2 are connected by flange connectors 3, thus splicing them into a long strip-shaped side box section. After the front box section 1 is connected to the side box section, it forms a rectangular anti-collision body fitted onto the pier 7, completely surrounding the pier 7 to achieve comprehensive protection.

[0035] like Figure 2 and Figure 3As shown, the frontal box section 1 is a box structure with a triangular horizontal cross-section and a streamlined design for the impact face, effectively dispersing the impact force of the ship. The inner wall of the box section 11 is reinforced with circumferential ribs, filled with high-polymer foam energy-absorbing material 12, and coated with an anti-corrosion composite material layer, ensuring both structural strength and improved durability. Figure 4 As shown, each side box segment 2 of the side box section is also a box structure. The inner wall of the box 21 of the side box segment is provided with reinforcing ribs, the interior is filled with high-polymer foam energy-absorbing material 22, and the exterior is coated with an anti-corrosion composite material layer. Multiple side box segments 2 can be flexibly spliced ​​through flange connectors 3 to adapt to piers 7 of different sizes, thus enhancing the applicability of the device.

[0036] like Figure 5 and Figure 6 As shown, the flange connector 3 in this embodiment includes a front segment flange connector 31, a side segment flange connector 32, and connecting bolts 33. The front segment flange connector 31 is welded to the front box section 1 to form an integral unit, and the side segment flange connector 32 is welded to the side box section to form an integral unit. During construction, the side segment flange connector 32 is connected to the side segment flange connector 32 using the connecting bolts 33, so that the two side box sections 2 are spliced ​​into a side box section; then, the front segment flange connector 31 is connected to the side segment flange connector 32 using the connecting bolts 33, completing the connection between the front box section 1 and the side box section. The flange connector 3 enables the modular installation and disassembly of the steel-coated composite material anti-ship collision device for bridge piers using energy-absorbing fenders, significantly improving construction efficiency and reducing maintenance costs.

[0037] In addition, in this embodiment, a manhole 4 is provided at the bolt connection of the flange connector 3, which facilitates personnel to enter the device for inspection and maintenance. After construction is completed, the manhole 4 is sealed with a cover plate to ensure the sealing and safety of the device.

[0038] like Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, several energy-absorbing fenders 5 are installed on the inner sides of the front box section 1 and the side box section, i.e., on the side near the pier 7. Figure 7 As shown, the energy-absorbing fender 5 consists of an energy-absorbing fender base 51, an energy-absorbing anti-collision block 52, and a rubber pad 53. The energy-absorbing fender base 51 has a V-shaped seat structure and is fixed to the inner wall of the box section by bolts. The energy-absorbing anti-collision block 52 is installed on the energy-absorbing fender base 51, and the rubber pad 53 is installed on the side of the energy-absorbing anti-collision block 52 away from the base. The energy-absorbing fender 5 can effectively absorb the energy during a ship collision, reduce the damage to the pier 7, and prevent secondary damage to the pier 7.

[0039] Furthermore, as a preferred technical solution in this embodiment, considering ease of construction, such as Figure 5 As shown, in this embodiment, the top of the front box section 1 and each side box section 2 is provided with several lifting lugs 6. The lifting lugs 6 are used for hoisting operations during construction to ensure convenient installation of the device in deep water or complex environments.

[0040] Based on the above structural description, the modular design of this steel-clad composite material bridge pier anti-ship collision device with energy-absorbing fenders allows for rapid assembly of the front box section 1 and the side box sections via flange connectors 3, significantly improving construction efficiency. The lifting lugs 6 further simplify lifting operations, making it particularly suitable for installation in deep water or complex current conditions. This steel-clad composite material bridge pier anti-ship collision device with energy-absorbing fenders uses modular assembly; when a component is damaged by a ship collision, only the damaged part needs to be replaced, eliminating the need for complete replacement and significantly reducing maintenance costs. The highly efficient energy-absorbing design of the energy-absorbing fender 5 effectively absorbs impact energy, preventing secondary damage to the bridge pier 7 that traditional fenders might cause, thus improving the protective effect. The outer surface of the box is coated with an anti-corrosion composite material layer, and the inner wall is reinforced with ribs and filled with high-polymer foam energy-absorbing material, ensuring excellent corrosion resistance when the device is exposed to water for extended periods, thus extending its service life.
