Description

Изобретение относитс  к области испытани  горных пород дл  определени  их механических характеристик , в частности, дл  определени характеристик прочности, пластичности и ползучести пород Б услови х всестороннего сжати . известно устройство дл  определени  прочности горных пород при всестороннеы сжатии, содержащее ка иеру давлени , заполненную маслом. В нее помещают испытываемый образец . Камера имеет сложную конструкцию , что св зано с требованием ее герметичности. Испытанию образцов пород предшествует их обработка (покрытие маслонепроницаемой оболочкой) дл  предотвращени  проникновени  масла в поры образца. В предлагаемом устройстве боковое давление на образец создаетс  с помощью баллона, изготовленно го из эластичного материала и соединенно1о с источником давлени . Коно-грукци  устройства упрощаетс , так как отпадает необходимость в герметичной камере давлони . Это приводит к упрощению л уо коранию испытаний, На чертеже изображено предлагаемое устройство. Оно состоит из металлической обоймы I, внутри которой разыещйБ эластичный баллон 2, соединенный с источником давлени  патрубком 3. При таком выполнении система бокового давлени  замкнута, гзрматична и изолирована от образца 4, помещаемого внутрь устройства. Это позвол ет производить испытание образцов непосредственно после их из готовлени  без предварительной обработки , что существенно повышвет производительность испытаний пород Осевое давление создаетс  испытательной машиной (прессом) и передеетс  на образец через нагрузочные торцовые диски 5 и 6.The invention relates to the field of testing rocks to determine their mechanical characteristics, in particular, to determine the characteristics of strength, ductility and creep of rocks under conditions of comprehensive compression. A device is known for determining the strength of rocks under comprehensive compression, which contains a pressure chamber filled with oil. Place the test sample in it. The chamber has a complex structure, which is connected with the requirement of its tightness. Testing of rock samples is preceded by their treatment (oil-resistant coating) to prevent oil from entering the sample pores. In the proposed device, lateral pressure on the sample is created using a balloon made of elastic material and connected to a pressure source. The design of the device is simplified, since there is no need for a pressurized pressure chamber. This leads to a simplification of tests, the drawing shows the proposed device. It consists of a metal cage I, inside which a flexible cylinder 2 is connected, which is connected to a pressure source by a pipe 3. In this configuration, the lateral pressure system is closed, closed and isolated from sample 4 placed inside the device. This allows the testing of samples directly from their preparation without pretreatment, which significantly increases the productivity of rock testing. Axial pressure is created by a testing machine (press) and transferred to the sample through loading end disks 5 and 6.
