The selection criterion of effective technologies in the manufacture of monolithic reinforced concrete piles in drilled wells

The problems of selection of efficient technologies for the production of monolithic reinforced concrete piles in drilled wells. This takes into account the results of the static tests produced piles, labor costs and the time allowed for the manufacture of 1 m3 volume of constructive piles (bored or CFA piles are on proposed technologies). Based on the performed analysis concludes that the main criterion for the selection of efficient technologies in monolithic reinforced concrete (bored or drilled wells in CFA) piles should be taken: the bearing capacity of the pile F_d according to static tests; Duration of manufacturing 1 m3 volume constructive piles (standard time); manufacturability of industrial processes.
