AI Technical Summary
In existing technologies, deep cement mixing piles suffer from problems such as insufficient mixing uniformity, inconvenience in grouting, and poor stability during drilling.
A deep cement mixing pile drilling and shotcreting assembly is adopted, including a drill rod with an internal hollow structure, multiple mixing components distributed on the bottom outer periphery, and synchronous reverse rotation of the mixing components through a gear linkage assembly. The shotcreting assembly is fixed on the outside of the drill rod, and the drive motor is installed at the bottom of the drill rod to reduce the transmission distance and improve stability.
It improves the uniformity of mixing, simplifies the installation of the shotcrete components, enhances convenience and sealing, reduces swaying during drilling, and improves the stability of the mixing pile.
