Description
(54) СПОСОБ ИЗМЕРЕНИЯ МЕХАНИЧЕСКИХ НАПРЯЖЕНИЙ В ГОРНЫХ ПОРОДАХ(54) METHOD OF MEASURING MECHANICAL STRESSES IN MOUNTAIN BREEDS
использовани малообъемного датчика с объемной щелью. Может быть создана внутренн поверхность щели с .рабочими мембранами датчика, который не уступает по своим физическим свойствам измер емому объекту - горной породе. Дл такого случа может быть использован бетон. Однако, залива датчик, а соответственно, и щель бетоном, получают заниженную чувствительность . Выходом вл етс пр мой контакт датчик - щель без вовлечени свободной поверхности щели.using a low-volume sensor with a bulk gap. An internal surface of the slit can be created with sensor working membranes, which are not inferior in their physical properties to the object being measured - a rock. Concrete can be used for this. However, the Gulf sensor, and accordingly, the crack in the concrete, receive an underestimated sensitivity. The output is a direct sensor-slit contact without involving the free surface of the slit.
Целью изобретени вл етс повыщение точности измерений с одновременным увеличением чувствительности.The aim of the invention is to increase the measurement accuracy while simultaneously increasing the sensitivity.
Это достигаетс тем, что по предлагаемому способу помещают в щель герметичный эластичный рукав, в котором создают давление, обеспечивающее его прижатие к породе, затем помещают в полость, образованную щелью и рукавом до соприкосновени с ним нерабочей поверхностью преобразователь деформации, зазор между рабочими поверхност .ми которого и породой заливают бетоном, а давление в преобразователе довод т до рабочего, причем давление в рукаве снимают после застывани бетона..This is achieved by the fact that according to the proposed method, a sealed elastic sleeve is placed in the slot, in which pressure is applied, ensuring that it is pressed against the rock, then placed in the cavity formed by the slot and sleeve until the deformation transducer touches it, the gap between the working surfaces of which the rock is poured with concrete, and the pressure in the converter is brought to the worker, and the pressure in the sleeve is removed after the concrete has cured ..
На чертеже изображен примеросущёствлени способа. Мембранный датчик 1 установлен на эластичном рукаве 2, между горной породой 3 и бетоном 4 и соединен трубкой 5 с регистратором 6. К одному из концов рукава подведено давление насосом 7.The drawing shows an adaptation of the method. The diaphragm sensor 1 is installed on an elastic sleeve 2, between the rock 3 and concrete 4, and is connected by tube 5 with a recorder 6. Pressure is supplied to one of the ends of the sleeve by pump 7.
Использование предлагаемого изобретени позвол ет использовать датчики одной конструкции в различных, измер емых объектах с повыщенной точностью, без уменьшени чувствительности, но с расщирением дианазона измерений, за счет сохранени The use of the present invention allows the use of sensors of the same design in different, measurable objects with increased accuracy, without desensitization, but with the expansion of the dianazone measurements, by preserving
малого объема чувствительного элемента и обеспечени надежного контакта с породой. ПрйМ енекие эластичного рукава позвол ет проводить измерени в короткие сроки, а сам рукав многократно использовать.small volume of the sensing element and ensuring reliable contact with the rock. The elastic sleeve allows for measurements in a short time, and the sleeve itself is reusable.
Использование предлагаемого изобретени уменьщает з.атраты на проектирование и производство чувствительных элементов в три раза..The use of the present invention reduces the cost of designing and producing sensitive elements by a factor of three.
