Description

Существующие консгрукцни приборов дл  измерени  давлени  пород при пучении основаны на том, что усили , возникающие в пучащей породе, определ ютс  путем периодической догрузки прибора, в результате чего сохран етс  первоначальный объем испытываемого образца.The existing congresses of instruments for measuring the pressure of rocks during heaving are based on the fact that the forces arising in the sheath rock are determined by periodically reloading the instrument, as a result of which the original volume of the test specimen is retained.

Описываемый прибор отличаетс  тем, что испытываемый образец породы занимает в нем посто нный объем, а возникающее при пучении образца давление измер етс  специально отградуированным манометром. Указанное отличие обеспечивает возможность изучени  динамики нарастани  давлени  пучащей породы во времени, чего нельз  достигнуть в приборах с периодической догрузкой.The described device is characterized in that the test sample of the rock occupies a constant volume in it, and the pressure that occurs when the sample is healed is measured with a specially calibrated pressure gauge. This difference makes it possible to study the dynamics of the buildup of the pressure of the pulling rock over time, which cannot be achieved in devices with periodic loading.

Кроме того, данный прибор позвол ет изучать вли ние химических реагентов на изменение давлени  пучап;ей породы.In addition, this device allows one to study the effect of chemical reagents on the change in pressure of the rock bottom.

Прибор состоит из металлического корпуса /, внутренн   часть которого разделена на две полости, изолированные диафрагмой Нижн   полость 3 заполн(хна жидкостью и соединена с манометром 6.The device consists of a metal case /, the inner part of which is divided into two cavities, isolated by a diaphragm. The lower cavity 3 is filled (henna with liquid and connected to a pressure gauge 6.

В верхней полости между двум  дырчатыми вкладыщами 4 и 5 но .мещаетс  образец испытываемо породы. Через отверсти  вкладышей поступает вода, увлажн юнта  образец породы. Вызванное пучением давление породы передаетс  через нижний дырчатый вкладыщ .) и диафрагму 2 на жидкость нижней полости прибора и фиксируетс  показанием манометра 6.In the upper cavity between the two perforated inserts 4 and 5, a sample of the test rock is placed. Water enters through the holes in the liners, moistening the rock specimen. The swelling-induced rock pressure is transmitted through the lower perforated liner.) And diaphragm 2 to the fluid in the lower cavity of the instrument and is recorded by the reading of a pressure gauge 6.
