Background
Bridges are buildings erected across unfavorable geology or to meet other requirements, and with the high development of bridge modernization, more and more bridges are used. After the bridge construction is finished and the normal operation is carried out, the pier top supporting seat needs to be periodically checked and maintained, and because the pier is generally higher, the pier top does not have a space for a maintainer to stand, the pier top hanging basket is installed after the pier construction is finished so as to provide an operation space for checking and maintaining.
The vertical bearing parts of the existing pier top hanging basket, namely the bracket, are all made of carbon steel Q235 and are angle steel welding components, and the step plate pedaled by people is a reinforced concrete precast slab or a steel grating plate.
The metal surface anticorrosion means of mound top hanging flower basket all adopts paint anticorrosion basically, just must carry out paint repair within 5 years usually, and local steel skeleton needs to be changed even, and the maintenance and management cost is high, and the potential safety hazard is many, takes place when leading to the casualties incident of maintainer, and recessive risk is with high costs.
At present, the metal corrosion prevention is performed by zinc impregnation in a more advanced mode. According to introduction of a paper & lt & ltbolt surface zinc impregnation corrosion prevention new technology test evaluation and popularization & application & gt published in a journal & lt 2014 12 months edition of China offshore oil gas & gt, the zinc impregnated bolt has better corrosion prevention effects in a marine atmospheric environment than those of electro-chromizing, hot dip galvanizing and Teflon. The zinc infiltrated railway spike and the zinc infiltrated guardrail can be protected for 30 years without damage and maintenance. However, the process of zincating is costly.
The main disadvantages of the above products are: firstly, the product is heavy and has high difficulty in transportation and installation; secondly, local corrosion is caused by local damage, the corrosion defect is developed rapidly, the function of a product is reduced rapidly and even loses efficacy easily, quality welding defects and corrosion prevention defects are easily generated at the welding position of the steel skeleton, the control and the inspection are difficult, and the safety accident of casualties of maintainers is easily caused; thirdly, the total cost in the 30-year life cycle is high, the overhaul period is short, and the maintenance cost is high.
