4 Overview

General technical requirements in accordance with GB/T 30040.1 requirements.

5 monitoring wells

Down 5.1 from the ground monitoring wells drilled formation, its minimum diameter of 300mm. 5.2 If a liquid sensor, the monitoring wells should surface extends down into the following positions further down the depth of at least 1.0m. a) the minimum normal water table; b) the lower end of the tank or pipe. 5.3 Choosing a), b) the lowest point of both. 5.4 If a vapor sensor, monitoring wells should surface extends down into the tank or pipe the lower end of the lowest point and then down at least Depth of 1.0m. 5.5 If there is a normal risk down to the water table monitoring wells above the radiation holes lowest opening 1.0m or less, use steam sensor. 5.6 Monitoring wells shall extend from the surface to the lowest point of the well casing, the sleeve is evenly covered with radiation holes in the vertical and circumferential directions. Distribution of radiation holes should allow the liquid at any height can enter the well, while preventing soil around the entry. Casing should have sufficient strength Degree, regardless of whether there is liquid monitoring wells, should not be damaged under the pressure of the surrounding land.
