  • Patent number: 10788408
    Abstract: A method for determining the diffusion radius of in-situ injection and remediation of contaminated soil and groundwater. According to the triangle method, the hole spacing is perpendicular to the groundwater flow direction, the row spacing is along the groundwater flow direction, and the flow diffusion in the groundwater during the effective time of the remediation agent reaction is considered. Under high pressure rotary injection, the remediation agent and a certain proportion of bromide ions are simultaneously injected into the aquifer as a tracer. The diffusion of the agent is determined by observing the phenomenon of slurry-returning and slurry-channeling of adjacent injection points. After the completion of the injection, the groundwater is quickly sampled in fixed depth, the tracer concentration is quickly detected on site, and the concentration of bromide ions in the groundwater is compared with the background value. Comprehensive determination determines the optimal diffusion radius.

  • Publication number: 20200240561
    Abstract: A system for connecting and sealing flexible and rigid pipes under high pressure comprises a flexible pipe, rigid pipes, and transition connectors, wherein two ends of each transition connector are respectively connected with the flexible pipe and one rigid pipe, external sides of the flexible pipe and the transition connectors are coated with a rubber layer, and buckling sleeves are buckled on the rubber layer outside the transition connectors. Compared with the prior, the system can greatly improve the sealing performance of the flexible pipe and the rigid pipes, and thus can be used under high-low temperature and high-pressure atmospheres and be applied to air-conditioning pipes of new-energy vehicles.

  • Patent number: 10682680
    Abstract: An in-situ chemical oxidation high pressure injection optimization remediation method for soil and groundwater. A field test determines the diffusion radius of the injection agent in a typical formation, the maximum single-hole grouting amount per linear meter and the injectability parameter. Density-increased supplementary investigation, soil and groundwater data analysis, is divided by spatial distribution into four concentration main partitions, eight concentration sub-partitions. By optimizing the single-hole grouting amount per linear meter, the preparation concentration of the oxidant, and the parameters of the formulation of each partition, the optimization of the dosing ratio of remediation agent of each partition is achieved. The specific construction performance is to adjust the lifting speed of the high pressure injection drill pipe during the injection process for finally achieve the purpose of reducing the dosing ratio parameters of the agent in the remediation plot.
