FIELD: building.
SUBSTANCE: invention relates to underground construction, in particular for lining excavations constructions, and may be used in shafts and mines and underground work in vertical urban infrastructure. Support consists of lining and hydraulic seal in form of non-hardening viscous fluid under pressure exceeding pressure of underground water. Hydraulic seal is arranged between rock walls and support. Near-wellbore material is strengthened with anchors, on which is used metal mesh. Above and below pressure level of underground water arranged circular watertight curtain. Lining and adjacent array mounted monitoring system comprising: liquid pressure sensors in hydraulic seals, rock mass displacement sensors, pressure sensors and water flow rate.
EFFECT: technical result is creating a structure lining, which allows to avoid ingress of water on plane of contact with array of lining, as well as area damaged during drilling and blasting rocks in previously flooded layers, more efficient use of lining materials and thus reducing consumption of materials.
