FIELD: construction.
SUBSTANCE: invention relates to the field of construction and can be used for control of deformations of bases of foundations of industrial and civil facilities constructed and operated in severe climatic conditions of the Far North at development of gas and oil deposits. Device for monitoring soil deformations in cryolite zone includes working pipes with support discs, protective pipes and glands. Pipes form separate links for measurement of deformations, consisting of working pipe with support disc and protective tube put on it, which are coaxially installed on anchor rod with using glands. Length of protective tubes is equal to distance between support disks of adjacent links with allowance for increasing coefficient (Kp), which depends on forecast value of soil tillage, the value of which is determined by the given relationship.
EFFECT: technical result consists in improvement of information value and reliability of monitoring results of deformations on the section of freezing and thawing soil bases of geotechnical hydrocarbon production systems and associated infrastructure.
