Оценка усилия вдавливания железобетонных свай заводского изготовления в глинистые грунты

Abstract

The article discusses the pile indentation equipment for dive prefabricated reinforced concrete piles which are used in clay soils in urban environments. It was developed in 2003 and intended for dive reinforced concrete piles of different cross-sectional (square, round, prismatic, ring, etc.) length from 5 to 12 meters. Different modifications (SVU-1, SVU-2 and SVU-3) have been prepared during the period of equipment’s exploitation. They have dived more than 35,000 prefabricated concrete piles in Tomsk, Novosibirsk, Omsk, Kemerovo and other cities of Russia. In 2011 specialists of “FundamentSpetsStroy” (Tomsk) and specialists from the Kuban State Agrarian University (Krasnodar) developed a special device-meter, which provides to get information on efforts of the indentation piles at predetermined elevations. The article describes a structure of device and its operating principle. The principle of device based on the conversion parameters of pressure hydraulic system of pile indentation equipment during the pile diving into an electrical signal that is converted to digital information. The article presents the main results of effort indentation of piles, also tables of received values and graphics. The article performed an analysis and the generalization results of experimental research.
