Abstract
Description
Technical Field
[0001] The utility model relates to the field of bridge pile foundations, in particular to a pile foundation ship collision resistant steel buoyancy box. Background Art
[0002] With the rapid development of inland waterway shipping, the number of inland navigable ships has gradually increased and their types have become more diversified. For old inland river bridges, in order to save investment costs, the lower structure was usually designed as a high-pile foundation structure, resulting in the pile foundation being exposed during the dry season. Since the single pile foundation has low stiffness and poor anti-collision ability, the problem of pile foundation anti-ship collision of bridges has become more prominent, posing a safety hazard to the bridge structure.
[0003] Steel pontoons are a commonly used anti-ship collision facility for bridge piers, but are rarely used in the field of pile foundation anti-ship collision. At present, the measures for pile foundation anti-ship collision are mostly to surround a circle of anti-collision barrels near the pile foundation. Each anti-collision barrel is connected by an iron chain. There is no filler in the anti-collision barrel. The surface of the barrel is coated with warning paint blocks, and a certain amount of rubber fenders are fixed on the bridge pier. This process cannot effectively reduce the impact of ships on pile foundations, and mainly serves as a warning. In terms of bridge anti-collision measures in China, most of them are bridge anti-collision measures for abutments or piers, and there are few anti-ship collision measures for pile foundations. There is a method of surrounding a circle of steel pontoons around the pile foundation and filling the steel pontoons with granular materials. This method can achieve multi-level buffering and thus reduce the impact of the impact, but the construction process is relatively complicated and the cost is relatively high.
[0004] Therefore, a pile foundation anti-ship collision steel buoy is needed to solve the above problems. Utility Model Content

[0036] Furthermore, the plurality of pads 20 and the sliding portion 30 are made of rubber material.
[0037] Furthermore, the cross section of the sliding portion 30 is in a U-shaped structure, and the U-shaped opening of the sliding portion 30 is arranged toward the inner wall surface of the steel pontoon structure 1 .
[0038] Furthermore, each straight cylinder 122 is provided with a plurality of connecting parts 40; the plurality of connecting parts 40 are arranged on the left and right inner walls of the steel pontoon structure 1, each connecting part 40 is fixedly connected to a sliding part 30, and the U-shaped opening of the sliding part 30 on the connecting part 40 faces the direction of the incoming ship.
