FIELD: construction.
SUBSTANCE: invention relates to construction, in particular for repair in zone of alternating water horizon and for repair of side and end surfaces of hydroelectric power plants piers. Device for repair of hydraulic facilities includes prefabricated sectional frame with bearing working platform and pump, moreover, sections of prefabricated sectional frame are hingedly connected to each other, and joints between its sections are fully tightened, prefabricated sectional frame is separated with bearing working platform by height into upper and lower compartments, at the same time in lower compartment there is a pump installed, interacting with system for water drainage arranged in prefabricated sectional frame, and tightening seals. Device is equipped with rectangular frame fixed on hydraulic facility and hingedly connected to end side of prefabricated sectional frame. On upper compartment of each section of prefabricated sectional frame there is a pneumatic cylinder installed, interacting with neighbouring section. Tightening seals are arranged as pneumatic. Shape of prefabricated sectional frame from the side inverted to repaired surface follows shape of hydraulic facility along line of contact with it.
EFFECT: invention provides for the possibility to simultaneously repair both side and end surfaces of hydraulic facilities, including piers having broken configuration and protruding parts.
