Based on the collecting device, a method for collecting columnar sediments can be further provided, and the method comprises the following specific steps:
firstly, a first external thread movable joint 1.4 at the upper end of a sampling pipe 1 is in threaded connection with a first internal thread movable joint 2.9 at the lower end of an air path control pipe 2 at a sampling place, a second external thread movable joint 2.7 at the upper end of the air path control pipe 2 is in threaded connection with a second internal thread movable joint 3.3 at the lower end of a first connecting rod 3, and a third external thread movable joint 3.2 at the upper end of the first connecting rod 3 is in threaded connection with a third internal thread movable joint 4.3 at the lower end of a second connecting rod 4.

Then, according to the fluffiness of the sediment, the pulling-out mode of the sampling tube 1 is selected.

Finally, the second ball valve 2.14 is opened, and the sample slides out of the sampling tube 1 by gravity. However, if the sediment is dense, the manual pulling-out process may be subjected to large resistance, the reaction force may cause the operator to fall into water or a puddle, and in such a state that the operator cannot be directly pulled out, the inflator 1.10 may be utilized to press gas into the sediment at the lower end of the sampling tube 1.1 through the gas hose 1.6 and the gas path steel pipe 1.5, and gas pressure is utilized to form a gas gap around the sampling tube 1, so that the sampling tube 1 can be separated from the sediment, and the sampling tube 1 is taken out by matching the pulling force of the sampler through the self buoyancy. In this state, the sediment cannot fall off from the sampling tube 1.1 under the action of gravity due to being dense, so that the air is pressed into the headspace of the sampling tube 1 through the air tap 2.12 on the left side of the air passage control tube 2 by using the inflator 1.10, and the sample is extruded out of the sampling tube 1 by using the air pressure.
Furthermore, if the integrity of the sample is required to be high, and it is desired to maintain the sample in its original layered form, the sample can be brought back to the laboratory together with the sampling tube 1. The method at this time is as follows: after sampling, a sample is retained in the sampling cylinder 1.1, then the first internal thread union 2.9 is separated from the first external thread union 1.4, the first external thread union 1.4 at the top end of the sampling tube 1 is sealed by using the sampling tube internal thread plug 1.8, and the bottom end of the sampling tube 1 is sealed by using the sampling tube smooth plug 1.9, so that a sampled sediment sample is retained in the sampling tube 1. The sampling tube 1 is transported back to a laboratory for subsequent treatment in a vertical state, and vibration is avoided as much as possible in the transportation process.
The above-mentioned embodiments are merely a preferred embodiment of the present invention, but it is not intended to limit the present invention. Various changes and modifications can be made by one of ordinary skill in the pertinent art without departing from the spirit and scope of the present invention. Therefore, all the technical schemes obtained by adopting the mode of equivalent replacement or equivalent transformation fall within the protection scope of the utility model.
