Description
Изобретение относитс к приборам дл определени сопротивлени грунтов сдвигу в полевых услови х с применением дл испытуемого образца двух, расположенных одна над другой, обойм, из которых нижн установлена на подвижной каретке, перемещаемой при помощи устройства рычажного типа.The invention relates to devices for determining soil resistance to shear under field conditions with application to the test specimen two, one above the other, clips, of which the bottom one is mounted on a movable carriage moved with a lever-type device.
Зар дка исследуемым грунтом известных такого рода приборов, производитс с применением грунтоотборной гильзы, из которой после выравнивани двух открытых ее граней образец грунта выдавливаетс в обойму прибора.Charging with the studied soil of such known devices is carried out using a soil pick-up sleeve, from which, after leveling two open faces, a soil sample is squeezed into the holder of the device.
Такой способ зар дки не обеспечивает ненарушенное состо ние природной структуры грунта, что снижает точность результатов испытаний.This method of charging does not ensure the undisturbed state of the natural structure of the soil, which reduces the accuracy of the test results.
В описанном приборе этот недостаток устранен применением в качестве нижней обоймы прибора грунтоотборной гильзы. Така конструкци прибора освобождает от необходимости выталкивани образца грунта из гильзы в обойму прибора, обеспечива этим ненарушенную структуру грунта.In the described device, this disadvantage is eliminated by using a pick-up sleeve as the bottom holder. Such a device design frees the user from having to push a sample of the soil from the sleeve into the holder of the device, thereby ensuring an undisturbed soil structure.
На чертеже изображен предлагаемый прибор в продольном вертикальном разрезе.The drawing shows the proposed device in a longitudinal vertical section.
Предлагаемый прибор представл ет собой две, расположенные одна над другой обоймы / и 2, из которых нижн выполнена в виде грунтоотборной гильзы. На заостренные соприкасающиес кра обойм надевают раздвижное кольцо 3. Внутри обойм помещаетс испытуемый образец грунта 4. По верху и по низу его расположены пористые пластинки 5 и 6. На пористую пластинку 6 давит поршень 7, закрепленный на крышке обоймы 2. Весь прибор устанавливаетс на передвижной каретке 8, перемещаемой при помощи рычажного механизма.The proposed device consists of two, one above the other holder / and 2, of which the bottom is made in the form of a soil pick. Sliding ring 3 is put on the pointed contacting edges of the cages. Inside the cages is placed a test sample of the soil 4. On the top and at the bottom there are porous plates 5 and 6. On the porous plate 6 presses the piston 7 fixed on the casing cover 2. The whole device is mounted on a mobile the carriage 8, moved by a lever mechanism.
Вертикальные и горизонтальные усили , сообщаемые образцу поршнем 7 и рычажным механизмом 9 замер ютс мессурами 10 и П.The vertical and horizontal forces imparted to the sample by the piston 7 and the lever mechanism 9 are measured by massams 10 and P.
Схема действи прибора следующа : на острый край грунтоотборной гильзы / с образцом грунта надеваетс раздвижное кольцо 3, гильза /The device’s operation is as follows: on the sharp edge of the extraction sleeve / with a soil sample, the sliding ring 3 is put on, the sleeve /
