Abstract: Изобретение относится к области строительства, в частности к устройству свайных фундаментов из забивных свай заводского изготовления, погружаемых при отрицательных температурах в сезонно-мерзлый грунт. Способ погружения свай в сезонно-мерзлый грунт включает предварительную проходку скважин термовибролидером в местах погружения свай, выполненным в виде цилиндрической полой штанги с наконечником с одной стороны и жестко соединенным фланцем с противоположной, на котором установлен вибрационный погружатель, с последующей окончательной забивкой свай в полученные скважины. Термовибролидер установлен на мачте копра, реализующего погружение свай, на смежной ее грани со свайным молотом, между наконечником и штангой расположен переходник, который жестко закреплен со штангой, а соединение с наконечником выполнено разъемным. Наконечник термовибролидера имеет конусообразную форму, в центральной полости которого размещен жаростойкий изолятор с винтовым пазом на наружной поверхности, вмещающим нагревающую спираль с большим удельным сопротивлением, между изолятором и переходником установлена жаростойкая упругая прокладка для исключения осевых перемещений изолятора. На наружной поверхности наконечника жестко закреплены радиально направленные ребра с внутренними продольными каналами, а в стенках наконечника выполнены поперечные радиально расположенные отверстия. Перед погружением термовибролидера наконечник нагревают и затем погружают в сезонно-мерзлый грунт при включенной спирали, а после разработки грунта термовибролидер извлекают. Технический результат состоит в повышении эффективности устройства свайных фундаментов зданий из забивных свай заводского изготовления, погружаемых при отрицательных температурах в сезонно-мерзлый грунт путем снижения затрат при устройстве фундаментов за счет исключения разрушения стволов свай при их погружении через мерзлый слой, а также уменьшения значений отклонений свай в плановом положении, позволяя увеличить скорость устройства скважин в мерзлых грунтах. 3 з.п. ф-лы, 3 ил.

Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to medicine, namely to a method for complex estimation of arterial bed state. Finger area is irradiated with a light signal of the red and infrared wavelength ranges. Ambient temperature and temperature of the finger area to be recorded are pre-stabilized and the clamp of the emitters and the photodetector to the finger is adjusted. Photoplethysmographic (PPG) signal is recorded for at least 5 minutes. PPG signal is contoured by signal filtration by Savitzky–Golay method with 64 ms window width and obtaining the fourth signal derivative. Direct and reflected wave of PPG signal is detected from the artery wall. Arterial stiffness is determined on the basis of time interval between direct and reflected waves and on the basis of their amplitudes. Complex continuous wavelet transformation of the PPG signal is carried out using a Morlet basis wavelet and generating a wavelet spectrum. Peak location of PPG signal power in the wavelet spectrum is determined. State of the microcirculatory bed is assessed by the arrangement of peaks in the frequency ranges corresponding to the microvascular tonus regulation mechanism. 
     EFFECT: invention provides accuracy, simplicity, reliability and reduced time for examination with integrated assessment of vascular bed for early diagnosis of widespread diseases - arterial hypertension and diabetes, in pathogenesis of which damage of arterial bed is of primary importance.
