Problems solved by technology

[0004] However, the water content test sensor of the earth taker is directly inserted into the sample soil for detection, and the sample soil will be disturbed by the water content test sensor, thereby destroying the structure, and the disturbed sample soil and the undisturbed sample soil are both in the thin-walled container. It is difficult to separate the two, so that the part of the sample soil that is finally sealed and transported to the laboratory is disturbed, resulting in a decrease in the accuracy of other subsequent tests on the sample soil

Abstract

The embodiment of the invention discloses an open type soil sampler, relates to the technical field of geotechnical engineering investigation, and solves the problem that a sample is disturbed while the water content of the soil sample is tested in situ. The open type soil sampler comprises a base, a detection assembly and a sample soil pipe, the base is used for being connected with a drill rod, the detection assembly is fixed to the base and comprises a detection soil pipe and a detection probe, the detection probe is located in the detection soil pipe, and the length of the detection probe in the extension direction of the detection soil pipe is smaller than that of the detection soil pipe; the sample soil pipe is detachably connected to one end, far away from the base, of the detection soil pipe and is used for sampling sample soil. The open type soil sampler is used for sampling a soil sample and measuring the water content of soil.

Description

technical field [0001] The embodiments of the present application relate to but are not limited to the field of geotechnical engineering investigation, and in particular, relate to an open-type soil borrower. Background technique [0002] Geotechnical engineering survey refers to the activities of ascertaining, analyzing and evaluating the geological and environmental characteristics and geotechnical engineering conditions of the construction site according to the requirements of the construction project, and compiling survey documents. Soil samples are tested indoors to determine the physical and mechanical parameters of soil in each soil layer, among which the water content of soil samples is a basic index, which has an important impact on the physical and mechanical properties of soil. [0003] In the soil fetcher of the related art, a water content test sensor is fixed on the upper end of the thin-walled device for taking soil samples, and the lower end of the ring-type ...
