Loading consolidation penetration tester

Abstract

The invention discloses a loading consolidation penetration tester. The loading consolidation penetration tester comprises an installation seat, a penetration meter, a penetration container, a consolidation pressure applying system and a pressure source, wherein the penetration meter and the penetration container are respectively arranged on the installation seat; the consolidation pressure applying system comprises a loading air cylinder and a loading platform; the penetration container comprises a container base, a soil sample ring cutter and an upper cover; the container base is arranged on the loading platform; the upper cover is fixedly connected on the installation seat through an installation frame; and the soil sample ring cutter is arranged between the container base and the upper cover in a vertically movable manner. Corresponding consolidation pressure is applied according to the soil depth of a soil sample, the pressure source is started, and the loading air cylinder jacks the loading platform to raise the container base gradually, so that the internal capacity of the soil sample ring cutter is gradually reduced, pressure applied to the soil sample in the soil sample ring cutter gradually increases, the on-site actual situation can be simulated vividly, and test errors are effectively reduced.

Description

technical field [0001] The invention relates to the technical field of geotechnical tests, in particular to a loading consolidation penetration tester. Background technique [0002] With the continuous development of the national economy, people pay more and more attention to the development and utilization of underground space in my country. Therefore, the application technology of civil architecture and geotechnical engineering and the testing requirements of various parameters of geotechnical tests are getting higher and higher. In particular, we should pay special attention to the progress and reliability of the measurement. For the current penetration test, the structure of the instrument and the test method often stay in the traditional technology of the 1950s, and it is impossible to get rid of this backward situation. [0003] At present, the conventional penetration tester is permeable without the action of consolidation pressure, which is not consistent with the a...

Problems solved by technology

For the current penetration test, the structure of the instrument and the test method often stay in the traditional technology of the 1950s, and it is impossible to get rid of this backward status quo

[0003] At present, the conventional penetration tester is permeable without consolidation pressure, which is not consistent with the actual situation of the load on the soil sample in the formation, and there are errors in the test results.
