Example Embodiment

[0033] The present invention will be further explained below in conjunction with the accompanying drawings of the specification.

[0034] Such as figure 1 and figure 2 As shown, a remodeling soil sample preparation device includes a base 1, a sample holding mold 2, a compactor 3, a positioner 4, a retaining rod 5 and a pressure plate 6; each part is made of stainless steel, and the positioning The device 4 is preferably made of high-strength stainless steel material in consideration of the factor of greater concentrated force.

[0035] The sample holding mold 2 is fixed on the base 1, and the top surface of the base 1 is provided with a base recess of a circular structure for the bottom end of the sample holding mold 2 to fall, which helps to better fix the sample holding mold 2.

[0036] The positioner 4 is sleeved on the clamping rod 5 and moved vertically along the rod body of the clamping rod 5 and then rotated in the horizontal direction to set the angle, and then the clamping ...

Abstract

The invention discloses a remoulding soil sample preparation device, comprising a base, a sample containing mould, a compacting instrument, a positioning device, a clamping rod and a bearing plate, wherein the sample containing mould is fixedly arranged on the base; the positioning device is sheathed on the clamping rod, is vertically moved along the body of the clamping rod, is rotated by a set angle along the horizontal direction, and is clamped on the clamping rod by a clamping mechanism to position the height of a sample; the compacting device and the bearing plate are respectively and fixedly arranged at both ends of the clamping rod; the diameter of the compacting device is matched with the inner diameter of the sample containing mould, the inner diameter of the positioning device is matched with the size of the clamping rod, and the outer diameter of the positioning device is greater than the outer diameter of the sample containing mould; after the compacting device compacts the sample, the bottom end surface of the positioning device is connected with the top end surface of an opening of the sample containing mould to prepare the sample; by changing the height of the sample positioned by the positioning device on the clamping rod, soil samples with different heights can be prepared. The remoulding soil sample preparation device has the advantages that the structure is simple, the operation is convenient, the accuracy is higher, the suitability is wide, and the number of sample compacting layers and the sample compacting height of each single layer can be flexibly changed according to different heights of the prepared samples.

Description

technical field [0001] The invention relates to a sample preparation device, in particular to a remolded soil sample preparation device, belonging to the sample preparation device used for soil engineering tests in the technical field of civil engineering. Background technique [0002] Indoor tests can accurately obtain various strength indicators required for soil engineering design, so as to be preserved as design and construction data. Usually test soil samples can be divided into original soil samples and remodeled soil samples. The undisturbed soil sample can better reflect the original structure of the soil, but it is highly sensitive to changes in the test environment and conditions, that is, a small change in the test conditions can cause a huge change in the test results. Due to the large dispersion of the test results of the undisturbed soil, the soil samples of the indoor test are usually remolded soil samples with stable properties and small test results. [00...
