Inqubo yokwelapha i-anti-corrosion yekholomu yokuvimbela umsindo:
1. Ukususwa kokugqwala nokwelashwa okunqanda ukugqwala kwamakholomu nezikrini zokuvimbela umsindo kuzohlangabezana nezimfuneko zedizayini nemithethonqubo efanele, futhi kuzothobelana nezinhlinzeko ezifanele ze-“Technical Conditions for Anticorrosion of Steel Structures for Expressway Traffic Engineering” (GB / T18226).2.Ngaphambi kokungena ku-hot-dip galvanizing yelungu lokuvimbela umsindo, ilungu kufanele lifakwe emanzini ukuze lenze isisekelo sensimbi sihlanzeke.3.Izingxenye zesakhiwo zensimbi zezithiyo zomsindo kufanele zibe yi-anticorrosive engaphezulu zilashwe ngokufaka ama-hot-dip galvanizing kanye nesifutho sepulasitiki ngemva kokuvuthela.4.Ukwelashwa kwe-hot-dip galvanizing: I-zinc esetshenziselwa i-hot-dip galvanizing akufanele ibe ngaphansi kune-ingot ekhethekile engu-No. 1 kanye ne-No. 1 ye-zinc ecaciswe ku-“Zinc Ingot” (GB / T470).
Inani lokucwenga lesendlalelo se-zinc akufanele libe ngaphansi kuka-610g / m2, futhi ubukhulu obujwayelekile bengqimba ye-zinc akufanele bube ngaphansi kwama-85um.5.I-Plastic coating emva kokuvuthwa kwesithiyo somsindo: Ingot ye-zinc esetshenziselwa ukugaya (ngaphakathi layer) inezidingo ezifanayo njengokwelashwa kokufaka ama-galvanizing dip.Ngaphansi kuka-61um.Ukujiya okungewona okwensimbi: i-polyvinyl chloride, i-polyethylene akufanele ibe ngaphansi kuka-0.25mm, i-polyester akufanele ibe ngaphansi kuka-0.076mm.6.Ukwelashwa kwe-anti-corrosion kwesithiyo somsindo kufanele kwenziwe ngemva kokuba ukucubungula kwengxenye sekuqediwe futhi ukuhlolwa kufanelekile.Uma ingxenye ngemva kokucutshungulwa kwe-anti-corrosion icutshungulwa futhi, indawo ecutshunguliwe kufanele ingabi nokugqwala.
