Description

Technical Field

[0001] The present invention relates to the field of dredging of monitoring wells, and particularly to a water quality monitoring method, a storage medium and a device for dredging operations of monitoring wells. Background Art

[0002] Groundwater is an important part of water resources. Groundwater monitoring can not only provide data support for scientifically obtaining groundwater resources, but also provide data guarantee for the rational development and utilization of groundwater. It is one of the objects of investigation and monitoring by hydrogeological and environmental geological departments. At present, setting a large number of shallow groundwater environmental quality monitoring wells is the main way and means to monitor groundwater.

[0003] The groundwater environmental monitoring wells set at the present stage belong to small-diameter shallow groundwater environmental monitoring wells, and their well walls are mostly protected by PVC pipes. Since the monitored aquifers are mainly Quaternary loose rock types, siltation is prone to occur generally, which directly affects the sample quality and even makes it impossible to conduct water quality sampling.

[0004] At the present stage, the commonly used dredging method is the drilling dredging method, which uses a drilling rig platform to drill and fish for slag, or combines high-pressure flushing with an air compressor. When the equipment of this method is used for dredging operations, the acting force is relatively large, and it is difficult to control the operation force in deep wells. It is not applicable to the monitoring wells with PVC pipe protection walls in small diameters. On the one hand, it is easy to damage the PVC pipe wall, resulting in the direct scrapping and reconstruction of the monitoring well, causing serious economic losses. On the other hand, the existing method equipment is not convenient to observe whether the water quality in the monitoring well is turbid and whether the pipe wall is silted up during operation, and the dredging efficiency is low. On the other hand, most of the equipment using the traditional drilling dredging method is large equipment, and the groundwater environmental monitoring wells are mostly set in places with inconvenient transportation or unopen areas, which is not conducive to dredging operations.

[0005] At the present stage, the dredging means and the dredging device are separated from each other, entirely depending on the experience of the operator, without an operation scale, and the randomness is too strong, making it difficult to achieve automated operation.

[0006] Therefore, it is necessary to provide a water quality monitoring method for dredging operations of monitoring wells to solve the above technical problems. Summary of the Invention

[0007] The present invention provides a water quality monitoring method for dredging operations of monitoring wells, which solves the problems of complex operation and low working efficiency of the existing dredging methods.
