【 Building materials network 】On the morning of September 28, Jinhu County, Huai'an Highway Management Office organized the conference of Huai'an 2011 national and provincial trunk highway bridge metal Railing At the completion acceptance meeting of the anti-corrosion and painting project, the construction period of the project is from March 2011 to June 2011, with a total of 4568.393m2 of rust removal, anti-corrosion and painting of 13 bridges on the trunk highway completed, including 3078m2 of one bridge on Provincial Highway 331 in Jinhu County; There are 7 bridges on 234 Provincial Highway in Chuzhou District, 1129.487m2, and 5 bridges on 2235 Provincial Highway, 360.906m2; The total investment of the project is 863100 yuan. The owner of the project is Huai'an Highway Management Office, the owner's representatives are Chuzhou District and Jinhu County Highway Management Station, the construction unit is Guannan Branch of Taizhou Jincan Metal Anticorrosion Coating Co., Ltd., and the supervision unit is Huai'an Tengda Engineering Testing Center Co., Ltd.
　　
In order to timely restore the intact condition of the bridge and improve the appearance of the bridge railings, the municipal highway will implement maintenance, anti-corrosion and painting works on the metal railings of the national and provincial trunk bridges within its jurisdiction. Metal railings for highway bridges are generally made of seamless Steel pipe Made of, extremely easy to rust, traditional maintenance methods are used Sandpaper Brush after polishing and derusting anticorrosive paint The appearance effect is general and not durable, and a certain amount of money needs to be invested every year for repeated treatment. For this reason, the municipal highway department decided to refer to the gate door Anticorrosion technology, innovative maintenance means, on-site thermal zinc spraying for corrosion prevention after sand blasting and rust removal, and brush coating outside the zinc layer epoxy Zinc rich Primer Add two layers Topcoat Processing. Although the one-time investment is high, the industry estimates that the anti-corrosion and antirust effect can be maintained for more than 10 years, and the finish effect can also be maintained for 3 to 5 years. Compared with traditional maintenance methods, it saves more manpower, material resources and funds, achieving the effect of one-time investment and long-term income. This technology has achieved good results after implementation in 2009 and 2010.
　　
On the basis of listening to the report, reviewing the completion documents and on-site inspection, the completion acceptance committee, after careful discussion, unanimously assessed the project quality as excellent, and agreed to pass the completion acceptance. The project quality defect liability period is two years.
