Изобретение относитс к инженерно-геологическим изыскани м дл строительства , в частности к устройствам дл определени прочностных свойств мерзлых грунтов.The invention relates to engineering and geological surveys for construction, in particular, to devices for determining the strength properties of frozen soils.
Цель изобретени - повышение точности измерений за счет устранени паразитных деформаций грунта.The purpose of the invention is to improve the measurement accuracy by eliminating parasitic deformations of the soil.
На чертеже представлено устройство , общий вид.The drawing shows the device, General view.
Устройство дл испытаний мерзлых грунтов на прочность и ползучесть состоит из основани 1, на котором жестко закреплены две стойки 2, снабженные ос ми 3 с посаженными на них эксцентриками 4, соединенными руко тью 5. На экспентрики 4 опираетс кольцо 6, приваренное к пуансону 7.The device for testing frozen soils for strength and creep consists of a base 1, on which two pillars 2 are rigidly fixed, equipped with axes 3 with eccentrics 4 mounted on them, connected by a handle 5. The ring 6 welded to the punch 7 is supported on the exprentrics 4.
Устройство работает следующим образом .The device works as follows.
На основание 1 под пуансоном 7, соосно с ним устанавливают образец 8 мерзлого грунта, затем с помощью руко ти 5 эксцентрики ввод т в соприкосновение с пуансоном 7 через кольцо 6, обеспечива минимальный зазор между образцом и пуансоном, определ емый по результатам тарировки .Дал ее с помощью нагрузочного винта через образцовый динамометр (не показано) прикладывают требуемую в опыте нагрузку (до 10 кН). На измерительном приспособлении (не показано) берутс начальные отсчеты. Включают секундомерOn the base 1 under the punch 7, sample 8 of the frozen ground is installed coaxially with it, then using the handle 5, the eccentrics are brought into contact with the punch 7 through the ring 6, providing the minimum clearance between the sample and the punch, determined from the calibration results. with the help of a loading screw, a model load (up to 10 kN) is applied through an exemplary dynamometer (not shown). On the measuring device (not shown), initial readings are taken. Include a stopwatch
и вывод т эксцентрики 4 из соприкосновени с кольцом 6 пуансона 7. Все нагрузки практически мгновенно пере- с даютс , на образец 8.and the eccentrics 4 are brought out of contact with the ring 6 of the punch 7. All loads are transferred almost instantaneously to sample 8.
Устройство позвол ет определ ть параметры прочности и ползучести из опытов на одноосное сжатие динамометрическим методом с высокой надежностью и обеспечивает достоверность полученных результатов. Кроме того, существенно упрощаетс обработка данных экспериментов, так как отсутствуют начальные деформации образца .The device makes it possible to determine the strength and creep parameters from experiments on uniaxial compression using a torque method with high reliability and ensures the reliability of the results obtained. In addition, the processing of experimental data is greatly simplified, since there are no initial deformations of the sample.
