METHOD OF STEAM HEATING OF CONCRETE SLOPE CHEMISES IN WINTERTIME

摘要

FIELD: construction.;SUBSTANCE: method of steam heating of concrete slope chemises in wintertime including concrete heaters with heat insulation. Steam boiler is set below the heating system, which is laid on concrete or into the concrete in the slope of the dam and consists of a tube with a pressure sensor at the end of the heating system placed in a snake-shape with moderate reverse grade for water run-off into the steam boiler and is covered with heat insulation. After assembling air is pumped out from the heating system and steam boiler and the entire system gets under pressured.;EFFECT: improved quality of chemise due to even concrete heating along its entire area and decreased power consumption of works.;2 cl, 4 dwg
