The present invention will be described in detail with reference to the following embodiments.
The utility model relates to a permafrost original state soil sample, transportation and save integrated device, the device includes the sampler barrel, and the sampler barrel includes transparent urceolus 1 and inner tube 2, has seted up extraction opening 6 on the inner tube 2, is provided with vacuum valve 4 on the urceolus 1.
The two ends of the outer cylinder 1 are closed and divided into an upper section and a lower section which are respectively a cylinder cover and a cylinder body. One end of the inner cylinder 2 is closed, and the other end is provided with a separated end plate which is respectively a cylinder body and a cover plate. A transverse supporting column 3 is connected between the cylinder body of the inner cylinder 2 and the cylinder body of the outer cylinder 1, and a vertical supporting column 3 is connected between the cover plate of the inner cylinder 2 and the cylinder cover of the outer cylinder 1. The supporting columns 3 between the cylinder body of the inner cylinder 2 and the cylinder body of the outer cylinder 1 are spirally arranged from top to bottom.

In order to prevent the gradual loss of the vacuum degree in the sampling cylinder, vacuum sealant can be prepared in advance, and after the original sample of frozen soil is sampled, vacuum sealing treatment is adopted at the joint position. One day before geological drilling in a frozen soil area, a plurality of bottles of tap water are pre-frozen in a laboratory and used as a self-supply cold source of a sample box. And meanwhile, a plurality of parts of flexible heat-insulating materials are prepared and used for the layered anti-collision and heat-insulating effects of the sampling cylinder in the sample box.
In geological drilling of the frozen soil area, an original frozen soil sampling device for field drilling is adopted, and after the original frozen soil core is cut into standard sizes (phi 110mm x 200mm (h)), the original frozen soil core is placed into the inner barrel 2 of the sampling barrel. The inner wall of the inner barrel is coated with vaseline in advance, so that the frozen soil sample and the inner wall are prevented from being frozen, and the later sampling is difficult.
After frozen soil original state appearance sample is taken a sample, screw up the cover, scribble the sealed glue of vacuum and smear in joint department, open vacuum valve 4 simultaneously, utilize hand-held type vacuum pump bowl evacuation, vacuum pressure in the monitoring sample barrel simultaneously. And after the vacuum pressure in the sampling cylinder reaches-90 KPa, stopping pumping, closing the vacuum valve 4, sticking a sample label, and finishing the sampling process of the original frozen soil sample.

The length and width of the sample box meet the integral multiple of the outer diameter of the outer cylinder 1 of the sampling cylinder, so that the sampling cylinders can be closely arranged in the sample box, and jolting in the transportation process is prevented. Each layer of sample should be placed with a bottle of frozen tap water as a cold source for the layer. When the sampling box is filled with the original frozen soil sample, the sampling box is placed in a shady and cool place in the shade to prevent direct sunlight. And after the drilling work is finished every day, uniformly sending the drilling work into a laboratory for testing frozen soil parameters.
When the original sample of the typical frozen soil needs to be stored for a long time, the original sample can be directly sent into a freezer of a frozen soil sample storage for storage without additional treatment.
