Annual flood, mud-rock flow take place frequently, and do great damage to the bridge facility in traffic, even destroy, form great
Security risk seriously constrains local economic development, threatens people's life and property safety.Foamed aluminium Bridge Pier body is answered
With can protect bridge to greatest extent, in the maintenance in later period, a large amount of human and material resources, financial resources can be saved, be bridge
Safety, expanding economy provide guarantee.Traditional Bridge Pier cover is made of macromolecule chemical industry material, this shield
Defect be need to make at the scene, and be it is fixedly mounted, be not available for local replacing, weather resistance is poor, and different aging can not
Environment is polluted in recycling.Traditional Bridge Pier cover cannot be effectively prevented mudstone drift sand, the mutual friction of sandstone phase, hit bring
It destroys, and the phase mutual friction, shock of rainwater and sandstone month after month throughout the year eventually leads to bridge pier bottom and is corroded, degenerates, it is only remaining
Reinforcing bar pillar.Certainly will thus influence whether the robustness of bridge pier, thus occur ground it is not firm, it is easy collapse etc. perils.
Some bridge piers use some protective devices at present, these protective devices are broadly divided into two kinds: one is outside bridge pier
Portion is surrounded with steel plate, intermediate cementing, but when by big impact, outer protective does not have the effect of energy-absorbing, generates big
Bridge pier can be equally damaged when deformation；Another is to be surrounded outside bridge pier using steel plate, intermediate polymeric foamed material, still
Under severe natural environmental condition, high molecular material is just quickly invalidated hardening, loses energy-absorbing function, causes shielding failure,
It cannot play the role of protecting bridge pier.

The energy of absorbable 3500KJ or more, compared with other polymeric foamed materials, foamed aluminium also has a nontoxicity, good weatherability,
Performance is stablized, corrosion resistance, agent of low hygroscopicity, not aging, will not with temperature, humidity variation and the characteristic that changes.
Matching foamed aluminium material protective device, Ke Yi are made according to the height of bridge pier, radius for the utility model
The energy absorption characteristics that foamed aluminium material is played when sandstone, water flow friction are washed away reach protection effect；The utility model uses steel plate+bubble
The composite construction of foam aluminium, can rounded, oval or special-shaped package, it can be achieved that multilayer is wrapped up, can the positive heart, eccentric package, can be real
Existing modularized production；The utility model can take into account Wear-proof, anticollision both protective actions, strong applicability, flexible high-efficiency, just
It is prompt quick.
On the one hand the utility model makes full use of the property of foamed aluminium material, half arc-shaped device is made, and forms foam
Aluminium protective device protects bridge pier, ensure that the solidity and robustness of bridge pier.On the other hand, when the bridge for needing to protect is in certainly
When the more severe mountain area of right condition, the utility model can realize the Al-Qaeda terrorist organization's modularized production, live Fast Installation, because it is
It is composed of two parts arc tube, in the maintenance in later period, local replacing can be carried out according to field condition, can saved big
The human and material resources of amount, financial resources.
