Quality Control Points for Reducing the Qualified Period of TBM Pipe Segment Coating Adhesion
The quality of anti-corrosion coating for TBM pipe segments is increasingly valued in large-scale water conservancy projects.Only after the anti-corrosion coating of the pipe segments is qualified can they be allowed to enter the site and installed.The qualification period for adhesion of anti-corrosion coatings is generally 7 days,and the qualification period for coatings is relatively long,which poses a risk of non-compliance with requirements for pipe storage sites and construction periods.The subsequent optimization project of Hanjiang Rongjiang Lianjiang water system connection has adopted practical and feasible TBM pipe segment coating construction quality control measures,reducing the qualified period of coating adhesion and improving the spraying quality.
