South-to-North Water Diversion Project
2025-04-11
Project Name: Replacement Project for Underwater Lining Plates of the Middle Route of the South-to-North Water Diversion Project
Material Application: MB-963 underwater epoxy coating adhesive, MB plastic filler
Processing Result: The Phase I project of the Middle Route of the South-to-North Water Diversion Project started construction in December 2003 and officially started water diversion in December 2014, with a total length of 1432 kilometers. The open channel surface uses a prefabricated lining plate structure for seepage prevention and protection. After commissioning, some lining plates were cracked and needed underwater replacement. The newly replaced lining plates use a snap-fit assembly structure. After assembly, the assembly joints need to be sealed and protected with effective filling materials. The protective materials need to be suitable for underwater construction and able to adapt to the deformation and displacement of the lining plate structure. After investigation and selection, it was decided to use MB-963 underwater epoxy coating adhesive and MB plastic filler for the underwater lining plate replacement and joint repair construction. The following year's underwater inspection showed that the joints filled with MB-963 underwater coating adhesive and MB plastic filler remained intact, and the lining plates were undamaged.
