The present application belongs to the technical field of environmental protection, and relates to a multifunctional well for risk management and control of soil organic pollutants and an operation method thereof. The multifunctional well comprises a segmented shell well pipe, a filter layer, a water stop layer and other components. The outer side of the well pipe is segmented and surrounded by the filter layer and the water stop layer according to functional requirements. The inside of the well pipe is provided with a soil gas guide pipe, a groundwater guide pipe and an online monitoring device. The upper part of the well pipe is provided with a volatile organic compound adsorption device. The top of the well pipe is a concealed well platform below the ground. The operation method comprises groundwater and soil gas monitoring, abnormality early warning and emergency disposal measures. Compared with the prior art, the multifunctional well has the advantages of integrated design, reduced repeated construction of groundwater monitoring wells and other functional wells, reduced number of well construction, shortened construction period and saved investment cost. Meanwhile, the multifunctional well can long-term online monitor pollutants, water level and pressure in the multi-phase medium, take emergency measures in time in response to abnormal conditions in the blocking structure, and effectively prevent pollution leakage risks.

This utility model discloses a mobile mud uniform spraying device, belonging to the technical field of spraying devices. The mobile mud uniform spraying device includes a mobile spraying unit, the front end of which is connected to a mud spray pipe. In this utility model, the iris mechanism, in conjunction with the adjusting ring, can flexibly change the mud output diameter and flow rate to adapt to different construction scenarios, such as large-area rapid spraying and small-area fine spraying, ensuring spray uniformity and improving construction quality. The filtering and stirring device prevents sedimentation through stirring, filters and intercepts impurities, and the vibrator assists in feeding and preliminary impurity removal, ensuring the purity and fluidity of the mud, reducing nozzle clogging and other malfunctions, and extending equipment life.
