Abstract

The invention discloses a piston device and a method for reactivating an ineffective piezometer tube. The piston device comprises a supporting part; a water pump mounted on the supporting part; a stamping unit extending into the piezometer tube and communicating with the water pump; and a lifting unit mounted on the supporting part and connected with the upper end of the stamping unit. The methodfor reactivating the ineffective piezometric tube comprises the step of carrying out reactivation operation on the piezometric tube by adopting the piston device. The technical problem that in the prior art, a piezometer tube is difficult to treat after failing or water level change is insensitive after treatment is solved.

Description

technical field [0001] The invention relates to the technical field of seepage monitoring devices, in particular to a piston device for reviving a failed piezometric tube and a method thereof. Background technique [0002] Piezometric tubes are widely used in hydraulic engineering and play a very important role in observing the groundwater level of hydraulic structures. The water level data in piezometric tubes is an important indicator for judging whether hydraulic structures are safe. The internal safety monitoring of hydraulic structures is mainly realized by means of piezometric tubes, supplemented by an automatic monitoring system, which can keep abreast of changes in the internal uplift pressure of hydraulic structures. [0003] The water level in the piezometric tube reflects the groundwater level at the location of the piezometric tube, and its range of change is closely related to the change in the water level of the water body around the site; the water level in th...
