PIEZOMETER OF A HYDRAULIC STRUCTURE Russian patent published in 2023 - IPC E21B47/47 G01N33/24 

FIELD: hydraulic structures.

SUBSTANCE: piezometer of a hydraulic structure is used to measure the level of groundwater and can be used in construction, in particular in the field of engineering surveys for construction, observation wells, drinking water supply wells. The piezometer has a metal pipe 1 buried in the ground with a perforated water intake part. The pipe is made of separate joined and welded sections. The lower section is equipped with a conical tip, in the upper part of which there is a broadening in the form of a disk. The barrel of the perforated metal pipe 1 is wrapped with a foam metal filter 5. The filter 5 is located along the height of the entire perforated pipe. The diameter of the pipe 1 together with the thickness of the filter 5 does not exceed the diameter of the disk.

EFFECT: design of the well makes it possible to reduce the pressing force of the metal pipe, to exclude filter shift and to ensure convenient immersion of the pipe into the ground and the arrangement of the piezometer.
