SU95805A1 - Instrument for determining internal displacements in a soil mass - Google Patents

Description

A known method for determining internal displacements in a group of armaments is that marks of one form or another are introduced into the ground, to which rods are attached that extend to the surface. The relative displacement of the rods of the rods makes it possible to judge the displacements of the soil of the iB Masaiw.

By design, even (both m and lead rods are relatively large in size, when immersing grades in the ground, it is necessary to disrupt the integrity of its array and cause accuracy to be measured).

The precaution of the device being shredded is that, as stamps, permanent magnets were used to inject into the soil from the well from the well, for subsequent determination (where the solenoid was lowered into the well and connected to the galvanometer) was used. in its grades, which improves the accuracy of ground motion displacements, where the instrument being described makes it easier to work and reduce its workload.

FIG. 1 shows a general view of the device in section; in fig. 2-cuts sections of the fixture designed to press marks into the soil and fig. 3-transverse cuts of the same prosobosbleki with successive positions gzhla.dyysch when outside of the magnet in the array of soil.

The device includes a tube 1 made of a diamagnetic material and a solenoid 5, reinforced by Tia on the base 3. The solenoid g 2 is connected to wire and 4 with a galvan 01 meter (not shown in the drawing).

The device is lowered into a pre-arranged well, from which stamps are fixed into the ground | D1vleni- agvity 5. When Jupuhanie solenoid 2 goes through tube 1, it crosses the magnetic field of each mark. The position of the magnet mark is determined by the greatest deviation of the needle of the galvanometer. Pressing the magnets 5 into the soil ocynie№ 95805, ..,.

It is a special device. It is oostait from tube 6 with holes 7 in the wall. Inside the rub1K (and along its entire length, the guiding strips 8 are placed. The slats 8 are fitted with inserts 9, which can be moved horizontally with (vertically; tube position 6.) Each slot has 9 slots; there is a groove in which This magnet 5 magnet 5 is prismatic in shape. The magnets 5 are located against the holes 7, through which HE | I are pressed into the ground by the impact.

After pressurizing the 1 magnet 5 into the ground, the inserts 9 are retracted back from the openings 7 with the help of a second rod 11. Then the tube 6 flows out of the well and has the tube / instrument immersed.
