Description

Дл  испытани  образцов грунта на компрессию обычно примен ютс  рычажные приборы, в которых давление по площади испытуемого образца -распредел етс  неравномерно, особенно при значительной усадке последнего.For testing soil samples for compression, lever instruments are usually used, in which the pressure over the area of the test sample is unevenly distributed, especially with a significant shrinkage of the latter.

Дл  устранени  указанного недостатка предлагаетс  гидравлический прибор, схематическое устройство которого указано на чертеже.To eliminate this drawback, a hydraulic device is proposed, a schematic device of which is indicated in the drawing.

На фиг. 1 показан вид прибора сверху; на фиг. 2 - разрез по линии А-Л; на фиг. 3- разрез по линии В-В.FIG. 1 shows a top view of the device; in fig. 2 - section along the line A – L; in fig. 3-section along the line BB.

Прибор работает по принципу гидравлического домкрата. Подавае .мое через трубку 12 давление передаетс  рабочей жидкости, заполн ющей нижнюю полость 3 цилиндра / прибора. В цилиндре 1 помеще- поршень 2, снабйсенный внутренним цилиндрическим углублением дл  испытуемого образца грунта 5.The device works on the principle of a hydraulic jack. Supply pressure via tube 12 is transferred to the working fluid filling the lower cavity 3 of the cylinder / device. In cylinder 1, there is a piston 2, provided with an internal cylindrical recess for the soil test sample 5.

На конусообразном дне углублени  в поршне 2, а также иод диском J9 распололсены металлические фильтры 4 и 6. Св зь между полостью поршн  2 дл  помещени  образца 5 и внешним пространством осуществл етс  при помощи отверстий 9 и W прибора. Сжимаемый поршнем 2 образец грунта 5, закрытый сверху диском 19, упираетс  в 35In the cone-shaped bottom of the recess in the piston 2, as well as the iodine disk J9, metal filters 4 and 6 are spaced apart. The connection between the cavity of the piston 2 for placing the sample 5 and the external space is made using the holes 9 and W of the device. A sample of soil 5 compressed by a piston 2, closed on top by disc 19, abuts against 35

неподвилчный парщег1Ь 7 и планку с кольцом, навертываемую на цилиндр / прибора поапе укладки образца грунта. Изменение высоты образца грунта замер етс  месс}рой 11, укрепленное, на окружности кольца плаики 8. Давление рабочей жидкости иод поршнем 2 замер ют манометром 13.basement par 7 and a bar with a ring screwed onto the cylinder / device for installing the soil sample. The change in the height of the soil sample is measured by mass} 11, reinforced, on the circumference of the plaque ring 8. The pressure of the working fluid iodine by the piston 2 is measured by a pressure gauge 13.

Дл  регулировки и установлени  требуемого давлени  иод поршнем 2 в приборе установлено специальное устройство.To adjust and establish the required pressure, iodine piston 2 has a special device installed in the device.

Деталь 14 этого устройства представл ет собой кран с таким расположением отверстий в его цилиндрической части, которое позвол ет прекращать доступ жидкости из трубки 15 под поршень 2 и в то же врем  открывать проход дл  рабочей жидкости из подвод щей трубки 18 в трубку 15. Трубка 15 енабжена грузовым иоршнем 16, предназначенным дл  регулировки величи ы давлени  посредством изменени  веса груза /7.The part 14 of this device is a valve with an arrangement of holes in its cylindrical part, which allows to stop the access of fluid from the tube 15 under the piston 2 and at the same time open the passage for the working fluid from the supply tube 18 to the tube 15. Tube 15 The cargo load 16 was designed to adjust the pressure by changing the weight of the load / 7.
