Embodiment Construction

[0041] The following will be described in detail in conjunction with the accompanying drawings and embodiments.

[0042] 1. Sample preparation device

[0043] 1. Overall

[0044] like figure 1 , 2 , the sample preparation device includes a base 1, a compaction cylinder 2 and a limit compaction cover 3;

[0045] From bottom to top, base 1, compaction cylinder 2 and limit compaction cover 3 are connected in sequence

[0046] 2. Functional components

[0047] 1) Base 1

[0048] like image 3 , the base 1 is a short cylinder, the outer diameter of the base 1 is consistent with the outer diameter of the outer sleeve 21;

[0049] The inner diameter of the base 1 is adapted to the outer diameter of the soil sample forming cylinder 22, that is, the top surface of the base 1 has a notch of the base 1 that the bottom end of the soil sample forming cylinder 22 of the compacting cylinder 2 falls into, which contributes to a better Firmly fix the compaction cylinder 2.

Abstract

The invention discloses a remoulded soil stratified compaction sample preparer for an indoor triaxial test and a method thereof and relates to a sample preparation technology of the indoor triaxial test. The sample preparer comprises a base, a compaction barrel and a limiting compaction cover; the base, the compaction barrel and the limiting compaction cover are successively connected from bottom to top; the base is a short cylinder; the compaction barrel comprises an outer sleeve, a soil sample forming barrel and a hooping bolt; the limiting compaction cover comprises a top cover and a limiting column connected up and down. According to the sample preparer disclosed by the invention, the thicknesses of the layers of the test sample can be guaranteed uniform, and the relative density is uniform; the sample preparer can be repeatedly used, and test samples of other specifications can be manufactured by changing the structure and dimension of a part; the sample preparer is simple in structure, convenient to disassemble, simple to operate, relatively low in cost, long in service life, accurate to prepare sample, efficient and reliable and small in interference by artificial factors; the sample preparation method is easy to master, high in universality, time- and labor-saving and convenient and rapid.

Description

technical field [0001] The invention relates to a sample preparation technology for an indoor triaxial test, in particular to a remolded soil layered compaction sample preparation device and a method for the indoor triaxial test. Background technique [0002] Various indicators required for engineering construction can be obtained through indoor tests, so as to be preserved as design and construction materials. Generally, before the triaxial test, it is necessary to prepare the test soil sample according to the geotechnical test regulations. In soil engineering tests, test soil samples can be divided into original samples and remodeled samples. The undisturbed sample is the sample of underground soil layer or rock ore layer that has not been disturbed by external force and maintained the original structure taken out by drilling. The original sample can better reflect the original structure and mechanical properties of the soil; however, sampling is difficult, the sample is...
