Description
(1) technical field
The utility model belongs to groundwater monitoring technical field, particularly a kind of single hole multilayer position Groundwater Monitoring.
(2) background technology
To monitor and the dynamic change characterization grasping underground water is scientific evaluation groundwater resources, formulates rational exploitation and utilization and effective protection measure, the important foundation alleviating and prevent and treat groundwater pollution and relevant geological disaster.Traditional groundwater level and water quality monitoring are generally utilize single wellhole facility, and for single target aquifer or mixing aquifer, the method taking field monitoring, remote monitoring and wellhole to sample is carried out.If want the water level and the water quality information that obtain a certain place different water cut layer, needing near locality, first by building multiple wellhole, and taking well-filling techniques method, form the groundwater monitoring wellhole of multiple different water cut position layer by layer, and then carry out water level and water quality monitoring.Such as, a certain place distributes three aquifer groups, there is different groundwater levels respectively, if need hydraulic connection and the water quality information of understanding different water cut layer underground water, so first, need according to formation lithology and aquifer distribution situation, build three degree of depth wellhole from shallow to deep, then in wellhole, monitoring pipe is laid, the principle in a target aquifer is only retained according to a wellhole, adopt well-filling techniques to build up the Groundwater Monitoring comprising three monitoring pipe, thus reach the target of monitoring different target aquifer groundwater level and water quality.The facility of this single hole single layer bit groundwater monitoring wellhole and method, not only floor space is many, engineering time is long, fund input is large, add the impact of the factors such as probing lapicide precision, well-filling techniques, be difficult to the complex characteristic such as the anisotropy really disclosing aquifer, correctly can not reflect the real-time dynamic-change information of underground water.For the Polluted area of underground water, because the change of zones of different aquifer, drilling hole are apart from increasing and artificially drilling reason, be difficult to capture the migration of pollutant under different water cut layer, different lithology condition, conversion and diffusion process.
