Latest Patents

One of his latest patents is an "Equipment and application method for sinkage detection and active escape of deep-sea mining vehicle." This invention includes sinkage detection and warning devices, as well as self-escape equipment. The detection devices are strategically installed on the left and right sides of each track of the deep-sea mining vehicle. They monitor the contact conditions between the tracks and the sediment, measuring the distance from the bottom of the track to the device. The self-escape equipment features an active interactive grouting system that connects to intelligent steering and retractable grouting heads, also located on each track. This invention allows for automatic detection of the complex driving environment of the seafloor and combines existing grouting technology to facilitate active escape in cases of excessive sinkage.

Another notable patent is the "Model test device and method for curtain grouting and excavation of tunnels in high-temperature, water-rich and weak strata." This invention comprises a weak strata simulation system, a working condition simulation system, a curtain grouting system, and a monitoring and data acquisition system. The weak strata simulation system serves as the main box for filling soft soil. The working condition simulation system includes a high geothermal simulation system and a water pressure simulation system. This invention effectively simulates the entire test process of grouting reinforcement and excavation in weak strata, providing valuable insights for actual soft stratum tunnel curtain grouting and safe excavation.
