Изобретение относитс к области исследований физических свойств грунтов , в частности к технике дл испы-. танин грунта и может быть использова. в меропри ти х по борьбе с ветровой эроэией почв.The invention relates to the field of research of the physical properties of soils, in particular to the test equipment. tannin soil and can be used. in measures to combat wind erosion of soil.
I , , Известно устройство дл испытани материалов на раст жение, содержащее .. удерживающие испытуемый образец сред- ства т гами, взаимодействующими с механизмом дл нагружени . С целью осуществлени испытаний в зко-упругих жидкостей удерживающие испытуемый образец средства выполнены в виде двух 15 цилиндров, снабженных на торцах втулками и крьваками, образующими .заполненные испытуемым материалом полости, Недостатком этого устройства вл етс сложность подготовки образца к 20 испытанию и низка надежность,его закреплени в цилиндрах 1.I,, A device for testing tensile materials containing .. means for holding a test specimen by means of traction, interacting with a mechanism for loading, is known. In order to carry out tests on visco-elastic liquids, the test sample holding means are made in the form of two 15 cylinders fitted at the ends with sleeves and sleeves forming cavities filled with the test material. The disadvantage of this device is the difficulty of preparing the sample for test and low reliability. fastening in cylinders 1.
По технической сущности и достигаемолу положительному эффекту наиболее близким к изобретению техническим ре-25 шением вл етс устройство дл ицпы-. тани грунтов на разрыв, включающее подвижную и неподвижную гильзы, сбеди I ненные между собой пружинной муфтой, и разрывное приспособление с индика- JIQ ГРУНТА НА РАЗРЫВBy technical essence and achievable positive effect, the closest to the invention technical solution is a device for testing. soil tears, including movable and stationary sleeves, sbie I interconnected spring clutch, and a discontinuous device with the indicator JIQ GROUND ON GAP
торами усилий. Крепление образца в гильзах происходит за счет прижимноЧ силы к цилиндрическим стенкам, развив вак дейс при уплотнений образца и набухании грунта в период водонасыщени 2}.tori effort. The sample is fastened in the sleeves due to the clamping force to the cylindrical walls, developing a wake-up during the compaction of the sample and swelling of the soil during the period of water saturation 2}.
Однако устройство позвол ет испытывать на разрыв только водонасыщенные образцы грунта и в зко-упругие жидкости и не может быть использовано дл испытани сыпучих дисперсных материалов , в том числе и частиц торф но-болотной почвы в сухом состо нии.However, the device allows only water-saturated soil samples and visco-elastic liquids to rupture and cannot be used to test loose particulate materials, including particles of peat-bog soil in a dry state.
Целью изобретени вл етс повышение точности измерени сцеплени между частицами сухого грунта.The aim of the invention is to improve the accuracy of measuring the adhesion between particles of dry soil.
Поставленна цель достигаетс тем, что и известном устройстве Включающем подвижную и неподвижную кюветы с захватами , установленное между ними кольцо, а также разрывное приспособление , индикатор усилий, кюветы снабжены штифтами с рифленной поверхностью , жестко закрепленными на внутренней поверхности оснований кювет. Упруго-в зко-пластичные свойства частиц почвы при любой влажчости позвол ют при сдавливании увеличивать поверхность контакта между частицами и штифтами, а также между самими This goal is achieved by the fact that the known device includes a movable and stationary cuvettes with grippers, a ring mounted between them, as well as a rupture device, a force indicator, the cuvettes are provided with pins with a grooved surface rigidly fixed on the inner surface of the bases of the cuvette. The elastic-visco-plastic properties of soil particles at any moisture content make it possible, upon compression, to increase the contact surface between particles and pins, as well as between
