A new design of an observation blowing well head

Summary

A new design of a blowing well head of underground water deposits is proposed. It is demonstrated that retrofitting the well head provides for the elimination of underground water spills from emergency wells; prevention of bog soils genesis, soil degradation and desertification on vast areas. The use of the well head ensures continuous hydrogeologic monitoring with the use of submersible stand-off sensors and recorders in blowing wells in different climate conditions on unguarded territories.

Unified head for the observation wells of drinking groundwater deposits

Summary

The authors of the article have developed a unified head of an observation well of drinking groundwater deposits, equipped with telemetric transmitting stations. This device was tested in the observation wells of the Avachinsky water intake of the Elizovski deposit of drinking groundwater (Kamchatka Krai). The results of measurements of the air temperature in the well showed that the thermal insulation casing prevented the occurrence of negative temperatures inside the ground part of the well thus providing for the reliable functioning of the power cells of the telemetry station in the autumn-winter period. A protective cover provided for the protection of the thermal insulation from the impact of ultraviolet radiation and moisture during the testing period.
