Pre-design inspection of prospect construction sites
Pre-design inspection of prospect construction sites aimed at detection of deep geological structures influencing the bearing capacity of foundations
Georadar survey of a river-crossing drilling route
A thawed zone of water-saturated sand is detected under the river channel along the horizontally-directed drilling route. The thawed zone is located between the profile marks of 200 and 280 m. The thawed zone extension depth is traced down to the 30 m mark as of the relative depth scale of the profile, or 18 m from the encroachment line.
To avoid contact of drilling equipment with water-saturated sand of the thawed zone, the recommended drilling depth must be above the 36 m mark as of the relative depth scale or 24 m from the encroachment line.
Work duration – 4 days
