Description

Technical Field

[0001] This invention relates to the field of bridge engineering, and more particularly to a floating bridge anchoring device. Background Technology

[0002] To enhance the urban landscape and create waterfront spaces, there is often a demand for waterfront walkways along riverbanks that have already undergone revetment renovation. Due to limitations such as land use and flood control, it is advisable to consider setting up floating bridges as pedestrian walkways close to the revetment within the river channel. In addition, some scenic areas also have a need to set up floating bridges close to the mountains.

[0003] Due to the influence of structures or mountains adjacent to the floating bridge, conventional cable anchoring systems cannot be used. The existing solutions are generally to drive anchor piles into the water or to drive anchor steel frames into the structures (mountains) and then connect them to the floating bridge.

[0004] If anchor piles are used, construction must be carried out near the revetment or mountainside, resulting in limited construction space and the need to construct cofferdams or floating construction platforms, leading to disadvantages such as long construction periods and high costs. Furthermore, pile foundation construction close to the revetment can compromise the safety of the revetment structure.

[0005] Anchoring steel frames to the structure (mountain) and then connecting them to the floating bridge would compromise the safety of the structure or the mountain. For existing revetment structures, since they are not within the design considerations, it is generally not permissible to add large-sized anchoring components. Furthermore, for mountains with poor rock integrity, this method of anchoring the floating bridge would obviously pose significant safety hazards. Summary of the Invention

[0006] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is that the existing floating bridge anchorage is close to the revetment or mountain on one side, and there is no condition to install anchoring cables. The construction of anchor piles near the revetment or mountain is limited by space constraints and requires the construction of cofferdams or floating construction platforms, resulting in long construction period and high cost. The addition of permanent structures such as anchor piles in the river channel is not conducive to flood control safety. The construction of anchor piles close to the revetment will affect the safety of the revetment structure. For existing revetment and other structures, the addition of anchor steel frame components will increase the structural load, damage the integrity of the existing structure, and affect the structural safety. The scheme of adding anchor steel frames is not suitable for problems such as mountains with poor rock integrity. This invention provides a floating bridge anchoring device that eliminates the need for anchor cables or anchor piles, requiring less space and making it particularly suitable for floating bridges located near revetments or mountains. It features an integrated design, simple construction, and low cost. Factory fabrication minimizes on-site installation work and facilitates rapid construction. No permanent structures such as anchor piles are needed within the river channel, minimizing impact on flood control and revetment structure safety. The anchoring components utilize small-diameter chemical anchors, having virtually no impact on the revetment or mountain structure. Through adaptive design, the anchoring device fits tightly against the revetment or mountain, providing buffering and limiting functions to ensure the overall stability of the floating bridge structure. The use of turnbuckles and quick-release pins ensures convenient assembly and disassembly of the floating bridge structure, positively impacting river flood discharge capacity, facilitating floating bridge maintenance, and simplifying revetment repair.

[0007] To achieve the above objectives, the present invention provides a floating bridge anchoring device, comprising a shell, a collision limiting block, a steel wire rope cable, and an anchoring ring. The collision limiting block is disposed inside the shell, the steel wire rope cable passes through the collision limiting block and is fixedly connected to the anchoring ring, the anchoring ring is fixed to the revetment or mountain, and the shell is connected and fixed to the floating bridge.

[0008] Furthermore, the anti-collision limiting block includes a solid rubber block, a steel wire rope cable sleeve, and an airbag compartment, which are connected to each other to form a whole.

[0009] Furthermore, the volume ratio of the solid rubber block to the airbag compartment is set to 2:1.

[0010] Furthermore, the casing is designed to be made of abrasion-resistant and waterproof material.

[0011] Furthermore, the wire rope cable sleeve is designed to penetrate a solid rubber block.

[0012] Furthermore, the wire rope cable sleeve is designed to penetrate the middle of the solid rubber block.

[0013] Furthermore, the wire rope cable also includes turnbuckles for connection to the anchor ring.

[0014] Furthermore, the outer shell is connected to the floating bridge via quick-release pins.

[0015] Furthermore, the airbag compartment is configured as a column, comprising two rows of airbag units, which are connected in parallel to form a sheet-like structure and inflated in series through an inflation tube.

[0016] Furthermore, the wire rope cable is configured as a tensionable wire rope cable.

[0017] Technical effect

[0018] This invention provides a floating bridge anchoring device that eliminates the need for anchor cables or anchor piles, requiring less space and making it particularly suitable for floating bridges located near revetments or mountains. Furthermore, the device employs an integrated design, resulting in a simple structure and low cost. Since the device is fabricated using tooling, installation is minimal and quick. Additionally, it eliminates the need for permanent structures like anchor piles within the river channel, minimizing impact on flood control and revetment structure safety, thus ensuring the safety of both the floating bridge and the revetment or mountain structure simultaneously.

[0019] The following will further explain the concept, specific structure, and technical effects of the present invention in conjunction with the accompanying drawings, so as to fully understand the purpose, features, and effects of the present invention. Attached Figure Description

[0022] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0023] In the following description, specific details, such as particular internal procedures and techniques, are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the invention. However, those skilled in the art will appreciate that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of the invention with unnecessary detail.

[0024] like Figure 1 and 2As shown, this invention provides a floating bridge anchoring device, including a shell, a collision-prevention limiting block, a steel wire rope cable 2, and an anchoring ring 1. The collision-prevention limiting block is disposed inside the shell 8. The steel wire rope cable 2 passes through the collision-prevention limiting block and is fixedly connected to the anchoring ring 1. The anchoring ring 1 is fixed to the revetment or mountain (structure). The shell is connected and fixed to the floating bridge. Each anchoring device is equipped with two steel wire rope cables to fix the collision-prevention block to the structure; the steel wire rope cables do not need to be fixed longitudinally.

[0025] The anti-collision limiting block comprises a solid rubber block 6, a steel wire rope sleeve 3, and an airbag compartment 5, which are interconnected to form a single unit. The volume ratio of the solid rubber block 6 to the airbag compartment 5 is set at 2:1. The airbag unit is cylindrical, with a diameter of 10cm and a length of 50-100cm, made of high-strength rubber material, and possesses a certain degree of flexibility. A one-way valve is installed at the air inlet, and the inflation port is connected in series with the inflation conduit. The airbag pack contains two rows of airbag units; each row of independent airbag units is connected in parallel to form a sheet-like structure, and inflated through a single inflation conduit.

[0026] The casing is designed to be made of abrasion-resistant and waterproof material.

[0027] The wire rope sleeve is designed to penetrate the solid rubber block. Further, the wire rope sleeve is designed to penetrate the middle of the solid rubber block. The wire rope cable is designed to be tensionable. The wire rope cable and the wire rope lock sleeve are integrally manufactured with the solid rubber block, with the wire rope sleeve pre-embedded in the solid rubber block. This embodiment of the floating bridge anchoring device, installed on one side of the floating bridge, adopts an integrated design. The solid rubber block, wire rope sleeve, airbag compartment, and other components adopt a sandwich structure, and are entirely encapsulated in an outer jacket made of wear-resistant and waterproof material. This greatly simplifies the construction of the traditional floating bridge anchoring system. In particular, the standardized and modular design effectively reduces project costs. Floating bridges near the revetment generally use a box-section, and the anchoring device uses a uniform specification unless there are special circumstances.

[0028] The wire rope cable also includes turnbuckles 4 for connection to the anchor ring.

[0029] The outer shell is connected to the floating bridge via quick-release pin 7.

[0030] This invention provides a floating bridge anchoring device. Depending on the floating bridge structure, one or more anti-collision anchoring devices are equipped on the side of each pontoon to reliably anchor the floating bridge structure. The pontoon height is defined as H, its length along the road direction as L, and the dimensions of a single anchoring device are: height h, length l, and width 0.6h. When h = H and L < 2l, one anchoring device is installed. When L ≥ 2l, one anchoring device is placed at each end of the pontoon, with anchoring devices evenly distributed towards the center. When the pontoons are small, each pontoon is equipped with a single anchoring device, and the anchoring devices are tightly connected, resulting in strong stability. When the pontoons are large, installing anchoring devices at both ends ensures the balance and stability of the pontoons, while additional anchoring devices are added in the middle as needed to make the structural connection tighter.

[0031] The method involves placing anti-collision limiting devices between the floating bridge and single-sided structures such as revetments and mountains to restrict the movement of the floating bridge toward the structure side; steel sleeves are installed in the anti-collision limiting blocks, through which tensionable steel wire ropes are threaded and anchored to the existing revetment or mountain to restrict the movement of the floating bridge away from the structure side.

[0032] The floating bridge anchoring device provided in this embodiment of the invention is mainly manufactured in the factory, reducing on-site installation and shortening the construction period. The integrated design of the anti-collision anchoring device means that after factory manufacturing, only the installation of anchor bolts needs to be completed on-site at the bridge site, which significantly reduces the amount of on-site work and greatly shortens the construction period. Furthermore, the construction process does not require the use of large machinery, which avoids disturbance to the riverbank soil and further ensures the stability and safety of the revetment foundation.

[0033] The steel wire rope is designed as a tensionable steel wire rope. The anchoring components implanted in the revetment or mountainside primarily bear the tension of the tensioned steel wire rope. The load is limited and controllable. In this embodiment, small-diameter chemical anchors are used, which have small opening sizes, are easy to install, and have minimal impact on the revetment or mountainside, causing virtually no damage to the existing structure. The installation process of the chemical anchors in this embodiment is as follows:

[0034] 1. Drilling the substrate: Use professional drilling tools, such as an impact hammer drill, to drill holes in the substrate;

[0035] 2. Clean the drill hole: Use a blower to blow away the dust inside the hole, and then use a special brush to clean the dust adhering to the inner wall of the hole (3 blows and 2 brushes);

[0036] 3. Inject the anchoring adhesive into the hole;

[0037] 4. Screw in the screw: Slowly screw the screw into the hole;

[0038] 5. Curing and maintenance: Allow the anchoring adhesive to cure naturally. The curing time depends on the temperature and should be referenced from the curing schedule. Do not rotate or knock the screw during the curing period.

[0039] The vertical movement of the anchoring device in this embodiment of the invention is mainly achieved through the relative sliding of the wire rope cable and the wire rope cable sleeve, as well as the deformation of the air bladder. After inflation, the air bladder size in the height direction is larger than the rubber block, and it can adapt to water level changes of ±0.5m through its own deformation. When the water level exceeds the above range, the air bladder is deflated and re-inflated. Therefore, the overall stability of the floating bridge structure is improved through the pretension of the wire rope cable and the air bladder structure. The anchoring device provided in this embodiment of the invention adopts an adaptive design. Under the pretension of the wire rope, the air bladder structure, which is close to the revetment or mountain, can fit tightly with the structure and play a buffering and limiting role, ensuring the integrity of the floating bridge structure under the effects of water flow force, wind force, wave force, and eccentric load.

[0040] The anchoring device is connected to the revetment or mountain via steel wire ropes with turnbuckles, and to the floating bridge structure via quick-release pins. Both connections use devices that are easy to assemble and disassemble, allowing the floating bridge to be quickly disconnected from the riverbank or the anchoring device when necessary. This ensures the ease of assembly and disassembly of the floating bridge structure, which is of positive significance for improving the flood discharge capacity of the river channel, facilitating the maintenance of the floating bridge, and making it easier to inspect the revetment.

[0041] An installation and construction scheme for a floating bridge anchoring device according to an embodiment of the present invention is as follows:

[0042] 1. Customize an integrated anchoring device based on the dimensions of the floating bridge and the surrounding environmental conditions;

[0043] 2. Determine the placement location of the limiting device, implant anchor bolts on the revetment or mountainside, and install tension steel wire ropes;

[0044] 3. After the pontoon bridge sections with anchoring devices installed are towed into place, the tensioned wire ropes are threaded into the sleeves;

[0045] 4. Use turnbuckles to gradually tension the steel wire rope, and adjust the airbags according to the flatness of the revetment or mountain surface to ensure that the limiting device is in close contact with the surface of the revetment or mountain.

[0046] 5. Secure the connectors between each pontoon bridge segment and install the bridge deck system.

[0047] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
