Embodiment 1

[0072] A kind of anti-collision and anti-corrosion steel pontoon of multi-stage buffer energy consumption type, its structure sees Figure 1 to Figure 22 As shown, it includes several anti-collision sections arranged around the pier or cap, and each anti-collision section includes:

[0073] The first level of cushioning - indentable rolling contact module A: includes a backing plate 8 sequentially stacked along the impact direction, a cylindrical folded belly energy-absorbing base 6, and a rolling assembly (metal roller) 7, wherein the cylindrical folded The abdominal energy-absorbing base 6 and the backing plate 8 are connected by welding, the backing plate 8 and the outer steel box 1 are provided with bolt holes 19 , and the backing plate 8 is connected with the outer steel box 1 through high-strength bolts 10 .

[0074] Second-stage energy absorption-sliding contact module B: including SA-type rubber fenders 9 stacked in sequence along the impact direction, the top surface ...

Embodiment 2

[0092] A kind of anti-collision and anti-corrosion steel pontoon of multi-stage buffer energy consumption type, its structure sees Figure 23 As shown, the difference from the first embodiment is that the rubber-like material (rubber tire) 5 passes through the uppermost welded longitudinal stiffening rib 3 on the outer steel box 1, and the vertical device is put into the outer steel box 1 and the inner steel box vertically in the axial direction. Space is reserved on both sides of the box 2, and longitudinal stiffening ribs 3 are arranged on the outer steel box 1 and the inner steel box 2.

[0093]The difference from Embodiment 1 is that the first-stage buffering-retractable rolling contact module is a square tube-shaped belly-folding energy-absorbing base 22. The structural diagram is shown in Figure 24 . A D-shaped rubber fender 21 is arranged in the second-stage energy-absorbing-sliding contact module.

[0094] Such as Figure 27 As shown, the crash-proof steel box in t...

Abstract

The invention relates to a multilevel buffering energy-consuming type bridge anti-collision device which is characterized by comprising a plurality of anti-collision sections; the anti-collision sections are arranged around a pier or a pile cap; each anti-collision section comprises an anti-corrosion steel box module which includes an inner steel box and an outer steel box; the anti-corrosion steel box module is divided into a post-collision anti-sinking submodule and an anti-collision submodule from bottom to top; a light high-polymer material is filled between the inner steel box and the outer steel box of the post-collision anti-sinking submodule; a rubber material is filled between the inner steel box and the outer steel box of the anti-collision submodule; a first-level buffering-retractable rolling contact module and a second-level energy-absorbing-sliding contact module are arranged on one side of the anti-corrosion steel box module close to a bridge structure. Compared with theprior art, the multilevel buffering energy-consuming type bridge anti-collision device is capable of realizing multi-level floatage prevention and ship collision prevention of the bridge structure; under different striking strength, the multilevel repairing of the device can be realized under the condition that the bridge structure is effectively protected; the excellent corrosion resistance of clad sheet steels is capable of solving the anticorrosion maintaining problem of the anti-collision device in rivers, lakes and oceans; engineering value and economic benefit are ultrahigh.

Description

technical field [0001] The invention relates to a bridge structure anti-floating device and a ship collision floating device, in particular to a multi-stage buffering and energy-consuming bridge anti-collision device. Background technique [0002] Engineering measures to reduce the risk of ship collisions on bridges. When the impact force of the ship is close to or much greater than the bearing capacity of the bridge pier, the anti-collision protection system attached to the bridge pier can protect the bridge pier from impact damage and avoid the resulting collapse of the bridge superstructure. In order to meet the requirements of bridge durability, even when the impact force of the ship is less than the carrying capacity of the pier, anti-ship facilities of corresponding scale can be installed to prevent damage to the durability of the pier such as the pier concrete being knocked down by the ship. [0003] Compared with fixed installations, floating installations are more ...
