Abstract

The application discloses an injection-reaction-monitoring integrated device for microbial improvement of contaminated soil, which comprises a tractor body, a bucket is arranged at the front end of the tractor body through a first turnover mechanism, a work platform is arranged at the rear end of the tractor body through a second turnover mechanism, a protective fence is fixedly connected to the top outer side of the work platform, a first air cylinder is fixedly connected to the inner wall of each of the two side protective fences, and a cross beam is drivingly connected to the output end of the first air cylinder. The multiple groups of downhole assemblies and grouting assemblies are matched to inject the improvement agent into the soil at different depths. The multiple groups of downhole assemblies and grouting assemblies can work synchronously, realize multi-point diffusion of the improvement agent, improve the uniformity of microbial distribution, and improve the operation efficiency. The device realizes accurate injection of the microbial nutrient solution in the contaminated site, reaction culture of the microorganisms in the soil, real-time monitoring of the repair process, and intelligent control and dynamic feedback of the whole microbial repair process.
