For control of reinforcement pile technology JSC drilling company "Delta" in conjunction with the American company PDI PileDynamicsInc. was introduced and adapted device TIP control termometričeskogo ThermalIntegrityProfiler. The basic principle of this equipment is based on the termometričeskom method of zameratemperatury-at tverdenii (catching) concrete energy of hydration. To do this, in piles in advance on the entire length of the lay a specific diameter metal tubes to move them termozonda with infra-red sensors. Number of pipes depends on the diameter of the pile. Depth sensor, coupled with the instrument TIP, tracks the position of the probe during the lowering of the full length of each tube. Data on temperatures and depths, usually going through the 12-48 hours after concreting depending on the composition of the concrete mix and the diameter of the borehole. Specialists of the company PDI PileDynamicsInc. empirically derived dependence diameter piles of concrete, temperature variations and measuring time. that is governed by ASTM D7949. I.e. the more concrete, the higher the allocated concrete temperature (energy of hydration) respectively, more diameter piles. The combination of measurements along the length of the piles generates a dependency graph of temperature from the diameter of the pile. Measurements in the field provide real-time see tentative schedule (profile) temperature curve describing the General form of the wells. At this level, the data obtained from the zamerahv one or more tubes, as well as during certain periods of time are collected for further analysis by trained specialists with the use of special software. Software developed by PDI PileDynamicsInc. allows you to obtain accurate 2D and 3D model researched piles.
