The utility model is suitable for a fields such as geotechnical test.

Description

Heavy dynamic sounding probe with sampling function

Technical Field

The utility model relates to a heavy power sounding probe with sample function mainly is applicable to fields such as geotechnical test.

Background

The heavy dynamic sounding probe is a common test instrument in a borehole geotechnical test, the hammering number of the heavy dynamic sounding probe can be used for reflecting the compaction degree of soil, the bearing capacity of a foundation and other engineering property indexes, and the heavy dynamic sounding probe is generally applied to engineering investigation.

The currently used heavy dynamic sounding probe does not obtain a soil sample, and the soil sample is obtained mainly by double-tube core drilling in engineering, so that the engineering property of soil is judged and the physical and mechanical indexes of the soil are provided. For some non-coring drilling, a test section soil sample cannot be directly obtained, and the material composition and properties of a test section soil body are known, so that the accurate judgment of a geological engineer on the engineering property of the soil is influenced.

Disclosure of Invention

The to-be-solved technical problem of the utility model is: aiming at the problems, the heavy dynamic sounding probe with the sampling function is simple in structure and convenient to manufacture.

The utility model adopts the technical proposal that: the utility model provides a heavy dynamic sounding probe with sample function which characterized in that: the middle lower part of the heavy dynamic sounding probe is provided with a sample storage hole which is arranged along the radial direction of the probe and penetrates through the probe.

The bottom plate of the sample storage hole is gradually concave from the orifices at the two ends of the sample storage hole to the middle to form a sample storage groove.

Heavy power sounding probe from top to bottom is linkage segment, this body section and probe tip section in proper order, and the body section divide into two sections from top to bottom, and the lower half section diameter of this body section from top to bottom crescent, store up the sample hole and be located the lower half section of this body section.

The diameter of the orifice of the sample storage hole is 20-30 mm.

The depth of the concave part at the bottom of the sample storage hole is 10 mm-30 mm.

The utility model has the advantages that: the utility model can obtain a certain amount of soil samples while the heavy dynamic sounding probe penetrates into the soil body by arranging the sample storage hole on the body section of the heavy dynamic sounding probe; the soil sample block is squeezed into or falls into the sample storage hole in the probe penetration process and is retained in the sample storage groove, so that the original structure can be preserved to a certain extent; the sample storage hole adopts a through structure and is easy to clean.

Detailed Description

As shown in fig. 1, the present embodiment is a heavy dynamic penetration probe with a sampling function, the heavy dynamic penetration probe 1 sequentially includes a connecting section 101, a body section 102 and a probe tip section 103 from top to bottom, the body section 102 is divided into an upper section and a lower section, and a diameter of a lower half 1021 of the body section is gradually increased from top to bottom.

As shown in fig. 2 and 3, in the present embodiment, a sample storage hole 2 is provided in the lower half 1021 of the body section 102, and the sample storage hole 2 is arranged along the radial direction of the probe and penetrates through the probe. The orifice of the sample storage hole 2 is positioned on the side surface of the lower half section 1021, the diameter of the orifice is 20-30 mm, and the diameter of the lower half section 1021 is gradually increased from top to bottom, so that the sample storage hole 2 is favorable for collecting dropped soil sample blocks.

In the embodiment, the bottom plate of the sample storage hole 2 is gradually concave from the openings at two ends of the sample storage hole to the middle, the concave depth is 10-30 mm, a sample storage groove 201 is formed, and soil sample blocks collected by the sample storage hole can be collected in the sample storage groove.

The method of use of this example is as follows: connect the drilling rod with heavy power sounding probe 1, put into the drilling, carry out heavy power sounding test, accomplish the hammering and penetrate the back, promote and take out heavy power sounding probe 1, pour out the soil sample from storing up appearance hole 2 behind the horizontal placement, to the soil sample of adhering to 2 inner walls in storage appearance hole, can clear up with stick or other instruments to avoid disturbing next time experimental. The color, maximum particle size, grading composition, water content and the like of the soil sample are described and recorded on a dynamic penetration test record table.
