AI Technical Summary
The construction of integrated pile and column components in existing tunnel conversion structures is difficult, has a long construction period, and has weak overall strength, especially in terms of controlling the verticality of the pile and column parts.
The same steel cage is used to run through the pile and column sections, combined with multi-layer steel mesh and stirrup structure to form an integral steel cage, so as to realize the simultaneous casting of the pile and column as a whole, which enhances the connection strength and construction convenience.
It improved the overall strength of the tunnel transition structure, simplified the construction process, shortened the construction period, and reduced the difficulty of verticality control.
