Изобретение относитс  к области ис следовани  медленных движений земной поверхности при контроле устойчивости горных выработок и крупных инженерных сооружений.The invention relates to the field of research of slow movements of the earth's surface while monitoring the stability of mine workings and large engineering structures.

Известные устройства дл  измерени  деформаций грунта, содержащие жесткий, iнапример, кварцевый стержень, закреплен вый одним концом в грунте, и регистриру клций прибор, имеют низкую чувствительность и большие габариты. Цель изобретени  - повышение точности и уменьшение размеров; стёржн.The known devices for measuring soil deformations containing a hard, for example, quartz rod, fixed at one end in the soil, and registering the instrument, have low sensitivity and large dimensions. The purpose of the invention is to increase accuracy and reduce size; stubs

Это достигаетс  тем, что стержень Iвыполнен изогнутым и другой его конец также жестко закреплен в грунте.This is achieved by the fact that the rod I is made curved and its other end is also rigidly fixed in the ground.

На чертеже изображено устройство, общий . ЧД- .. .„ Г Устройство представл ет собой кварце1вый стержень АБВГД диаметром 5-10 мм ; Стержень изогнут и его АБ -ГД закреплены между двум  цементными поста ментами . Постаменты или иные креплени  ; кварцевого стержн  жестко св заны с поI верхностью горных пород или любойThe drawing shows the device, the total. ChD -... G The device is a quartz rod ABCE with a diameter of 5-10 mm; The rod is bent and its AB-GD is fixed between two cement posts. Pedestals or other mountings; the quartz rod is rigidly connected to the surface of rocks or any

другой поверхностью, подлежащей исследованию на деформации. Середина кварцевого Стержн  В перемещаетс  BBefpx при сблн- : жжении постаментов и вниз при их рас сждении . Амплитуда этого пepe вщeиn  с-аль|ше амплитуды перемещени  постамен.ов ;относительно друг друга и зависит от на|чальной стрелы прогиба стержн  и его длицы. Например, применение изогнутого стержн  длиной 1 м и со стрелой прогиба ;примерно 0,5 см дает увеличение,соответ:ствукнцее работе п тидес тиметрового плоского . В точке В крепитс  любой из существующих регистрирующих приборов .another surface to be investigated for deformation. The middle of the quartz core B moves BBefpx when the pedestal is burning-: down and down when the pedestals are burning. The amplitude of this is opposite to the amplitude of displacement of the postamenes, relative to each other and depends on the initial deflection of the rod and its length. For example, the use of a curved rod with a length of 1 m and with a deflection boom of about 0.5 cm gives an increase, respectively, with a five-meter flat work. At point B, any of the existing recording devices is attached.
