Description

Submersibles are already known for taking soil samples from the bottom-hole and so on. wells that are equipped with a sampling tube, for example, the type of tube SPETSGEO, driven by the B soil of the shock load. This kind of grouping is: Kosam is a groundwater carrier according to the invention, but differs from them in that the load for driving the pipe into the ground is suspended on a rope. for lowering the soil tonnage into the well and placed in the pipe to the pipe. In the sequel, there is a BOcnpHnniMaocho anvil shock, connected to an intake tube. According to the invention, another feature of the soil toner is that the tube and the iraleeleur tube are connected with their relative longitudinal movement: neither do springing, absorbing the shock of the load.

The drawing shows in longitudinal section a grouser according to the invention.

Pipe 1 grouser, serves as the shell, m for placed in it

cargo 2, which with the help of nipple 3 is suspended on a steel cable that serves to lower into the well of the entire device. Pruzhiphbtii fopar 4, installed with the help of a copy rafiKM 5 on any borehole diameter, prevents the groundwater from rocking and strikes against the borehole walls. In the lower part of the tube 1, an anvil 6 is placed, perceived; and the load hits 2. In the anvil (screwed in nozzle 7, which can progressively move and nozzle 8. In turn, nozzle 8 is threaded to cover 9. Lid 9 and nav-wound On the anvil sleeve 10, they are connected to each other by a rubber cuff (11. The SPECGEO-13 probing tube is inserted into the cover 9, which has a rubber sleeve. A spring 12 is inserted into the cavity of the cavity between the nozzles 7 and 8 and the cuff 11, a spring 12 is inserted in the cavity and the die is attached to the head in the body in the body of the head in the body in the body of the p 5 in 8 and 8 and the cuff 11 in the cavity, and the end of the cushion is in the cavity of the head in the body in the body of the head and the body in the cavity in the body of the body in the body of the head of the body in the cavity and cover 9. Spring absorbs shocks The lateral movement of the tube 13 n pipe 1.

To take a sample of the soil, the groundwater is lowered to the bottom of the well, previously cleaned of sludge AND sludge using a normal one. Then, small shots of the HI stripping Mi cable to a height of 20-22 cm are struck, as a result of which the driver is pressed into the a-root. When the grounder closes Into the ground to a height of 15-18 cm, which can easily be seen on a cable, it is learned from the flow. from the well pas to the surface. This extraction represents labor, in addition to the low weight of the submersible (20 kg).

Practically, the on-board and uplift of the submersible should be done through a block, with a small tripod, in the absence of a derrick. Lift -; It is recommended that the device does not stop, but it should be completed as soon as possible.

The action of the submersible is based on the principle of the vacuum transfer of the sample to, the instrument 9 lid. The palpmie of two ball valves provides absolute sealing reliability, which prevents the specimen from falling out. According to the rpiiiHOHOca on the backside, determining the filter coefficient is directly in the tube 13, so that it is separated from the yoke 14.

The possibility of exploring the soil without overloading it into another room helps to preserve the natural structure of the soil.

Due to the insignificance of the frontal resistance of the SPECGEO-13 pipe itself, made of solid steel and having a wall thickness of only 2 mm, driving it into the ground does not cause changes in the texture of the soil. Bearing in mind that some experts still believe that shocks change the texture of the soil, it is possible to compare this soil test for crushing as well to compare the results. For this purpose, a pipe of 1 atvins; It comes from the incantation 6 and the last through the appropriate adapter can be attached to any shhtangs on which it can be lowered into the well, and the device will be pressed by the weight of the stem. However, the operation of the device with rods is more time consuming, as a result of which the illumination of the whole lithological section with the ground plane is as follows: these are very long time consuming.

The described soil tonnage is intended for granular soils and can work satisfactorily, 1 from the crust-grained Nesk with a grain diameter of 0.5–2 lsh, right up to the thinnest silty sands, except for slides. The presence of a small inclusion of small pebbles does not hinder the operation of the device, however, the presence in the sand of pebbles with a diameter of 3-4 cm can cause compression of the cutting face of the device.

At the end of the work, the device should be washed in water; for this purpose, the O1 start into the well to a certain depth under water. After flushing, the SPETSGEO tube is disconnected from the instrument and the entire device is dried and oiled to protect it from rust.

Subject invention

1. Grunthos for sampling of soil from the bottom of drilling and other wells, equipped with a sampling tube, such as SPECGEO, for example, & the ground is hit by a load, different in that the load 2 for driving a tube into the ground is suspended on a rope to put the submersible into the well and is placed in the guide tube 1 with the load-receiving load 2 on line 6 connected to the probaza (bar tube).

2. Forhg subsoil for l. 1, I differ from the one in that the sampling tube 13 and the guide tube 1 are connected with the possibility of their relative longitudinal movement and are pulled apart by a shock-absorbing shock of the spring.
