Abstract (en)

[origin: EP2009184A2] The method involves introducing hydraulically bonded materials in a bottom area of the bodies. A temperature gradient is measured (1) in a predetermined time span in an area of the double stop valve body. The temperature gradient is compared (4) with a predetermined part (2) of a predetermined multiple of another temperature gradient (3) in a comparison device. The temperature gradient has the smallest error deviation to the former temperature gradient, which is selected (7) as a temperature comparison gradient. An independent claim is also included for a drilling arrangement for ground drilling work.
