Description

Already known; groundwater borers for BLYBLISI samples; a rune, for example, from the bottom of a drill, etc., spabed with one inserted into another hollow cylinder / mi; in the gap between which are placed knives for cutting the soil sample from below, moving after pushing the cylinders onto the monolith cut out. Such plow shakers, however, do not provide for the preservation of natural composition in the sample of its soil.

The proposed soil toner, which is to eliminate the marked lack of already existing structures of the same type of soil, has the distinctive feature that for automatically moving the knives out of the gap between the walls of the cylinders, the spring associated with the knives is equipped with a trigger device and is controlled movably located piston of the internal cylinder.

In FIG. 1 shows a longitudinal section of an exemplary embodiment of the soil-carrier according to the invention; FIG. 2 is another longitudinal section of the soil carrier according to FIG. 1, and FIG. 3-slit it.

Grunthos consists of an outer 5 and an inner 8 hollow cylinder of wood, in the gap between the walls of which a pair of spherical knives 19 are placed, cutting the soil sample from below. For interaction with the last IH, a shock ring is intended - 16 external spring 14, connected by rods 7 with an abutment ring 13. bearing 12 springs 14 of the trigger device 14 on the springs 26 which support the inner cylinder 5 is screwed on the springs 26 of the spring 14 8. The shoe 3 is provided with guide slits along which the spherical knives 19 slide along when trimming the group sample. A cap 10 is screwed onto the inner cylinder 8, entering the outer cylinder 5. The head is screwed onto the upper end of the outer cylinder 5

11 rpyirroHoca, serving as an adapter to the working rods. Inside the cylinder: 8 and the bottom of the submachine carrier 3. The apparatus for cutting, holding and preserving the mounite, consisting of a proboprime glass 2, three cups 21, 22 and 23 inserted into it and a rotatable nipple 17 covering the cup 2. Bashmak 1 with cutting edges is screwed onto cup 2. This shoe also serves to support the lower one of stacks 21-23. The head 25 is screwed on the upper part of the cup 2, freely moving along the length of the inner cylinder 8. To avoid the turns of the cup 2, slots are made in its head 25, which include guide plates 9 located on the inner surface of the cylinder 8. At the top of the cup 2 there is a retainer consisting of a conical head 18 with a ball valve 15 connected to a hollow rod 20 with a piston M 24. The rod can freely move along the axis of the device through a round hole in the go; 25 lips of cup 2 2. In the inner core of the 8 core in the guide plates 9 machined window in which n and x axes placed two stop 6 is pressed against the head 18-sheet springs 4.

The rotating nipple 17 has a window equal in length to the circumference, and a height somewhat higher than the height of the middle cup 22. In the cup 2, there is also a similar cutout at the same level.

The action of the submersible is expressed in the following.

After stripping the well bore with known methods, the groundwater on the rods is lowered into the well at the position indicated in FIG. 1. With gradual pressure on the rods, the shoe 1 is pressed into the ground and the last, the entrance to the inside of the glasses 21, 22, 23, reaches the lower end of the piston 24, under the influence of which the latter moves to: top, excellent stops b to the sides. Air and water pass upward through valve 15. Head 25 cups 2 freely passes upwards

inside the cylinder 8 primertoos. Due to the large: ground resistance to the ground under the glass 2, the outer cylinder 5, together with the undercutting mechanism, begins to move downward, thrusting; cup 2 with soil that remains still. The stops b are then pressed to the sides. At that moment, when the conic head 18 reaches the latches 12. the latter are pushed to the sides and come off the projections of the inner cylinder 8. At this screw, the spring 14 fastened to the latches 12 by the springs 26 is released and begins to push down through the shock ring 16 onto the spherical knives 19. The latter exit through the slits of the shoe 3 and cut into the ground. The length of the cup 2 is made in such a way that when the head 18 touches the latches 12, the shoe I of this glass 2 is above the slots of the shoe 3 through which the knives 19 pass.

This completes the process of sampling the soil as a monolith, and removes the entire grounding surface of the nai. The spherical knives 19, due to the small difference in diameters, when working, do not close, but come one after the other, however, they carry over the ends of each other and fit tightly to each other, thus providing the necessary tightness.

In order to remove the soil from the device, the latter is turned off from the working rods, turned over, mounted on the head 11, and the shoe 3 with spherical pozhami 19 is turned off. The glass 2 from the ground is pulled out of the inner cylinder 8. The drawing does not show the device that keeps the valve valve 15 from slipping out of the socket when the ground is not turned, but it is not difficult to make it at all. Do not exclude the possibility of replacing a ball valve with a plate. The rotating nipple 17, which previously closed the window in glass 2, is rotated 180 °. as a result, the cutouts of the nipple and the glass are the same and the

Captrate them Medium Glass 2 can be removed. Before this, the upper and lower planes of the soil in the middle glass are trimmed with special PLANKSHI and thin meta / chic knives, made in the form of an elbow. Together with the paddles, the middle cup 22 with the primer is pulled out from the side of cup 2 and vaporized both from above and below; c) the form of the soil sample is sent to the laboratory. The dimensions of stack 22 can be made so that it serves as a ring of the compresonon device. If the glass is made split, it can also be placed without an overload of the soil sample into the shear production device. It should be noted that the presence of a rotating nipple 17 is optional, especially for taking monoliths from bonded soils. Attention is drawn to the fact that B1 analysis is average, less compressed, part of the soil. selected monolithic.

To charge the device, the spring screw 14 is compressed by pressing the shock ring 16 with a special key made in the pipe. At the same time, the latches 12, the income before the trench in the inner cylinder 8, drop these windows, holding back; further spring 14 in compressed state. The cup 2 is unscrewed from the head 24, and the cups 21 and 23 are cleaned of the soil remaining in them. Then, the groundworking bachmak 3 is rotated together with the spherical blades 19, the last ones are screwed into the gap between the cylinders 5 and 8, and the barrel 2 is screwed into the head 25. A new cup 22 is inserted into the notch of the cup 2, and the rotating nipple 17 turns back 180, closing the notch in glass 2. In such an in-plane, the submersible plane is ready to go down to the well to take a new sample.
