Problems solved by technology

[0004] Therefore, the technical problem to be solved by the present invention is that the existing sampler in the prior art disturbs the consolidated soil sample greatly when it is pressed into the bulk soil sample, and it is also difficult to cut and separate from the surrounding soil. problem, thus providing an indoor soil sample preparation method

Embodiment 1

[0048] like Figure 1 to Figure 5 As shown, the embodiment of the present invention provides an indoor soil sample preparation instrument, and the indoor soil sample preparation instrument includes a consolidation box 1 and a sampling pipe 14 .

[0049]Specifically, the bottom of the consolidation box 1 is entirely covered with a water filter layer, and the bottom of the consolidation box 1 is provided with a water outlet. The drained water from the consolidation of the soil samples can seep out through the water filter layer, and then drain out through the drain. The sampling pipe 14 has a cylindrical structure, the sampling pipe 14 is arranged in the consolidation box 1 , one end of the sampling pipe 14 is connected to the water filtering layer, and the sampling pipe 14 is connected to the water filtering layer There is a certain angle in between. That is to say, one end of the sampling tube 14 is directly inserted on the water filter layer, and the sampling tube 14 can be...

Abstract

The invention discloses an indoor soil sample preparation instrument. The indoor soil sample preparation instrument comprises: a consolidation box, a water filter layer is laid on the bottom, and a drainage port is arranged at the bottom of the consolidation box; a sampling tube is cylindrical. Structure; the sampling pipe is arranged in the consolidation box, one end of the sampling pipe is connected to the water filtration layer, and there is a certain angle between the sampling pipe and the water filtration layer. In this way, a sampling tube is installed in the consolidation box of the present invention. Compared with the existing sampler for pressing large soil samples, the present invention does not have the process of pressing the traditional sampling tube into soft clay, and realizes two-in-one sample preparation and sampling , so as to avoid disturbance to the soil sample, improve the sampling quality, and it is easier to cut and separate from the surrounding soil.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to an indoor soil sample preparation method. Background technique [0002] To quantitatively study the physical and mechanical properties of soft clay, soil samples need to be prepared by indoor consolidation. There are two main ideas for preparing soil samples for indoor geotechnical tests. The first is to place the soft clay slurry in the consolidation box, and then pre-compress and consolidate on the consolidation instrument; the second is to use vacuum pre-compression for consolidation. , which can accelerate the seepage of pore water in soft clay. After the consolidation was completed, soil samples were obtained from the bulk samples in the consolidation box with a sampler for geotechnical testing. [0003] At present, the soil samples prepared by the above methods are usually bulk soil samples, which cannot be directly used for indoor geotechnical tests. Th...
