Изобретение относитс к области изучени динамики взрывных процессов в грунтах, и может быть использовано дл записи деформаций в грунтах при распространении взрывной волны.The invention relates to the field of studying the dynamics of explosive processes in soils, and can be used to record deformations in soils during the propagation of a blast wave.
Известно устройство дл записи деформаций в грунтах при взрьовах, содержащее измерительный механизм в виде двух опорных элементов, первый из которых жестко св зан со штоком , взаимодействующим с датчиком, расположенным у второго элемента, и регистратор со стационарной мостиковой схемой 1.A device for recording deformations in soils with sprays is known, which contains a measuring mechanism in the form of two supporting elements, the first of which is rigidly connected with a rod interacting with a sensor located at the second element and a recorder with a fixed bridge circuit 1.
Недостатком такого устройства вл етс ограниченна область применени , поскольку св зь заглубленных опорных элементов вл етс упругОжесткой , вследствие чего он может регистрировать смещение грунта лишь в весьма узких пределах, а именно в пределах упругости пластин.The disadvantage of such a device is the limited field of application, since the connection of the submerged support elements is elastic. As a result, it can detect the displacement of the soil only within very narrow limits, namely within the elastic limits of the plates.
Наиболее близким к предлагаемому вл етс устройство дл записи деформаций в грунтах, содержащее два опорных элемента, первый из которых жестко св зан со штоком с возможностью перемещени вдоль второго опорного элемента, на которомClosest to the present invention is a device for recording deformations in soils, containing two supporting elements, the first of which is rigidly connected to the rod with the possibility of movement along the second supporting element, on which
закреплен преобразователь, и схему регистрации 2.The converter is fixed, and the registration scheme 2.
Недостатком такого устройства вл етс низка точность регистрации процесса деформации грунта при динамических нагрузках, так как не обеспечиваетс надежность контакта штока с датчиком.The disadvantage of such a device is the low accuracy of recording the process of soil deformation under dynamic loads, since it does not ensure reliable contact of the rod with the sensor.
Цель изобретени - повышение точности регистрации деформации грунта за счет обеспечени надежного контакта элементов преобразовател . The purpose of the invention is to improve the accuracy of recording the soil deformation by ensuring reliable contact of the converter elements.
Поставленна цель достигаетс тем, что в устройстве дл записи де15 формаций в грунтах, содержащем два опорных элемента, первый из которых жестко св зан со штоком с возможностью перемещени вдоль второго опорного элемента, на котором зак20 реплен преобразователь, и схему регистрации , на первом опорном элементе жестко закреплена направл юща гильза, а на втором - стакан с возможностыб продольного перемещени This goal is achieved by the fact that in a device for recording deformations in soils containing two support elements, the first of which is rigidly connected with the rod, can move along the second support element, on which the converter is closed, and the recording circuit, on the first support element the guide sleeve is rigidly fixed, and on the second - a glass with the possibility of a longitudinal movement
