FIELD: construction.
SUBSTANCE: application of a coating is carried out by preliminary manufacturing of a billet from a flaky composite material, the height of which is determined depending on the depth of freezing of local soil or height of physical wear of the inspection well neck. Mounting tapes are attached to one of the billet sides. The billet is impregnated with a binder. The produced coating is rolled into a roll with overlapping and is introduced into an inspection well with the help of a positioning rig until coating edges match the neck end. The coating position is fixed by connection of mounting tapes with the positioning rig. Hardening of the coating is provided by supply of compressed air and steam via a soft hollow puncheon lowered into the well neck. After hardening of the coating the puncheon is withdrawn.
EFFECT: simplification, acceleration and cost-effectiveness of a method.
