After installing the first concrete component, Yan Fei began the installation of the second piece, which was largely similar to the first in basic steps. However, at the juncture where two precast reinforced concrete components met, he adopted a mortise-and-tenon joint method, filling the area with cement to seal any gaps between them. This effectively not only connected the two precast reinforced concrete components but also prevented seawater from seeping into New Land through these gaps.
Yan Fei used the highest-grade cement, and the various components within the precast reinforced concrete were intricately matched, resulting in excellent thermal expansion and contraction properties. Even if he connected all the precast reinforced concrete components with cement without any gaps, he didn't need to worry about them cracking due to temperature changes.
