Abstract

The invention discloses a sampling and storage integrated undistributed soil sampling tool. The sampling and storage integrated undisturbed soil sampling tool comprises a sampling tool body, a storage seat, an upper cover plate and a cut-off closing tool; the sampling tool body is an annular tool body with a lower end surface being molded into a conical surface and a cylindrical sampling groove penetrating through the sampling tool body formed in the middle portion; a long-hole-shaped installation groove is formed in the upper end surface of the sampling tool body; a radius of the installation groove is greater than the radius of the sampling groove; the storage seat is arranged in the installation groove of the sampling tool body in a lifting manner; a cut-off groove with a long-hole-shaped cross section penetrating through the sampling tool body is formed in the middle portion of the sampling tool body; the upper cover plate is screwed onto the upper end surface of the sampling tool body; the cut-off closing tool can be arranged in the cut-off groove in a sliding manner; and the cut-off closing tool is detachably fixed on the lower end surface of the storage seat. The cut-off closing tool and the storage seat are detachably assembled and combine; when the cut-off closing tool and the storage seat are separated, the sampling tool is used for collecting the soil; and when the cut-off closing tool and the storage seat are combined, the sampling tool can be used for storage, so that the original state of an undisturbed soil sample is maximally maintained, and the transportation is facilitated.

Description

technical field [0001] The invention relates to a soil sample extraction technology, in particular to an undisturbed soil sampling tool integrating sampling and storage. Background technique [0002] In the traditional ring-knife soil sampling, first select the location for excavating the soil profile in the field, then excavate the soil profile, and sample in layers according to the profile level. Put the ring cutter holder on the ring cutter of known weight, press the edge of the ring cutter vertically downward into the soil until the ring cutter barrel is full of samples, then use the soil cutter to cut the soil around the ring cutter, and take out the filled sample. For the ring knife of soil, cut off the excess soil at both ends of the ring knife, and wipe off the soil outside the ring knife. Immediately cover both ends of the ring knife to prevent water from evaporating, then weigh and record. The process of capping the two ends of the ring knife is not easy, and it i...
