Description
Technical field
The present invention relates to bridge pier protection guard technical field, specifically a kind of foamed aluminium bridge pier protection guard and its making work
Skill.
Background technology
China has a vast territory, is mountain more than one, the country of more natural calamities, on the western parts such as Sichuan, Tibet, Guizhou and other places,
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 maintaining in later stage, 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 protective cover
Defect is to need to make at the scene, and is fixedly mounted, is 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, sandstone phase mutual friction, hit and 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.The robustness that certainly will thus influence whether bridge pier, to which the perils such as ground is unreal, easily caves in occur.
Some bridge piers use some protective devices at present, these protective devices are broadly divided into two kinds：Outside one is 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 surrounded using steel plate outside bridge pier, centre 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.
Invention content
The purpose of the present invention is to provide a kind of foamed aluminium bridge pier protection guard and its manufacture crafts, utilize the suction of foamed aluminium
Can effect, reduce sandstone, flow impact friction power and reach height protect.
To achieve the above object, the present invention provides the following technical solutions：

3）The assembly of arc tube：Foamed aluminium is assembled in steel plate and obtains arc tube, the upper arc method of welding in the upper surface of steel plate
Orchid, then location hole is bored on upper arc flange and arc lower flange, and spacer bar is mounted in location hole, finally in arc
Respectively weld a connecting flange for carrying adjustable elongated hole in the both ends of cylinder；
4）The processing of arc tube：Polished arc tube, preservative treatment, label mark, you can manufacture.
As a further solution of the present invention：The step 1）In, shaping includes rule circle, welds arc lower flange, described
Arc lower flange welding is in the lower surface of steel plate.
As a further solution of the present invention：The step 2）In, hot-pressing processing includes heating, pressure arc, shaping deburring.
Compared with prior art, the beneficial effects of the invention are as follows：
Foamed aluminium body is light, and damping and amortization is good, and damping capacity is 5-10 times of metallic aluminium, and bending resistance specific stiffness is 1.5 times of steel, energy absorption capacity
Good, the foamed aluminium that porosity is 84% can absorb the energy of 2500KJ or more when 50% deformation occurs, external steel body with it
After cooperation, energy absorption performance is substantially improved 50% or more, i.e., the foamed aluminium that porosity is 84% can be inhaled when 50% deformation occurs
The energy for receiving 3500KJ or more, compared with other polymeric foamed materials, foamed aluminium also has nontoxicity, good weatherability, performance
Stablize, 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 is made according to the height of bridge pier, radius by the present invention, can sandstone,
The energy absorption characteristics that foamed aluminium material is played when flow friction is washed away reach protection effect；The present invention is answered using steel plate+foamed aluminium
Close structure, can rounded, oval or special-shaped package, it can be achieved that multilayer is wrapped up, can the positive heart, eccentric package, it can be achieved that modularization
Production；The present invention can take into account Wear-proof, anticollision both protective actions, strong applicability, flexible high-efficiency, convenient quickly.
One aspect of the present invention makes full use of the property of foamed aluminium material, and half arc-shaped device is made, and it is anti-to form foamed aluminium
Protection unit protects bridge pier, ensure that the solidity and robustness of bridge pier.On the other hand, when the bridge that needs protect is in nature item
When the more severe mountain area of part, the Al-Qaeda terrorist organization's modularized production, live Fast Installation, because it is by two parts can be achieved in the present invention
Arc tube is composed, and in the maintaining in later stage, can be carried out local replacing according to field condition, can be saved a large amount of people
Power, material resources, financial resources.
