Description
Отличие описываемого устройства дл компенсации температурного вли ни при измерении микроподвижек горных пород заключаетс в применении металлических стержней с различными коэффициентами линейного расширени . Такое выполнение устройства обеспечивает повышение точности измерени .The difference of the described device to compensate for the temperature effect when measuring micro-movements of rocks is the use of metal rods with different linear expansion coefficients. This embodiment of the device provides improved measurement accuracy.
На чертеже изображено описываемое устройство.The drawing shows the described device.
Устройство состоит из двух реперов /, закладываемых в грунт, двух .металлических стержней 2, а также из измерителвного прибора 5 с поддерживающим его репером 4. Металлические стержни 2 одними концами прикреплены к выступающим концам реперов /. На свободных концах .металлических стержней расположен измерительный прибор 3Стержни изготовл ют различной длины и из различного материала.The device consists of two reference points / laid in the ground, two metal rods 2, as well as from a measuring device 5 with a rapper 4 supporting it. Metal rods 2 are attached at one end to the protruding ends of the reference frames /. At the free ends of the metal rods there is a measuring instrument 3 Rods are made of various lengths and of various materials.
Отношение длин стержней принимают обратно-пропорциональным «оэффициептам линейного расширени материалов. При таком выполнении устройства изменение длины стержней при колебании температуры компенсируетс и не отражаетс на показании измерительного прибора, который воспринимает лишь перемепгение реперов относительно друг друга.The ratio of the lengths of the rods take inversely proportional to the linear expansion coefficients of materials. With this design of the device, the change in the length of the rods when the temperature fluctuates is compensated and does not reflect on the reading of the measuring device, which perceives only the alternation of the frames relative to each other.
Предмет изобретени Subject invention
Устройство дл ко.мпенсации температурного вли ни при измерении микроподъижек горных пород, отличающеес тем, что, с целью повышени точности измерени , применены металлические стержни с различны.ми коэффициентами линейного расширени .A device for co-compensating the temperature effect in measuring micro-slides of rocks, characterized in that, in order to improve the measurement accuracy, metal rods with different linear expansion coefficients are used.
