Title: Yajun Qian: Innovator in Ground Reinforcement Techniques
Introduction
Yajun Qian is a notable inventor based in Nanjing, China. He has made significant contributions to the field of ground reinforcement, particularly through his innovative methods that enhance construction efficiency and reduce environmental impact.
Latest Patents
Yajun Qian holds a patent for a method titled "Method for reinforcing soft ground by post-grouting combined with air-boosted vacuum preloading." This method involves pre-burying prefabricated vertical drains and air-boosted pipes in granular material piles. The air-boosted pipes serve as grouting pipes, which reduces the number of piling operations required. This innovation not only improves construction efficiency but also minimizes structural disturbance to the soil and mitigates the smear effect. Consequently, it reduces the impact on radial permeability and radial consolidation coefficients. Notably, this method avoids the use of geotextile bags for granular materials, thus preventing localized clogging issues. It enhances the efficiency of vacuum transfer during the pre-consolidation stage and improves grouting effects in later stages, effectively strengthening soft soil and creating composite ground with granular material piles.
