Opyt zimnego in double prime etsirovaniya kanalov zhelezobetonnykh predvaritel'no napryazhennykh konstruktsii
Injection of channels in prestressed concrete construction in winter; efficient injection procedure which was applied in construction of vehicular bridges and viaducts at temperatures of -10 to -20 C; method consists of electric preheating of beams to about 35 C using reinforcement as heating elements, followed by injecting hot water (50 to 60 C); finally, electroheated mortar is injected and forces water out of channels.
