Abstract
The invention provides a tri-axial compression test soil sample demolding device which comprises a mold pressing part, a sample protecting part, a mold pressing needle and a protective part, wherein the mold pressing part comprises a base and a mold pressing rod, and a rotating groove is formed in the upper surface of the base; the sample protecting part comprises a soil sample placing layer, a circular mold falling layer and a sample protecting part rotating layer sequentially arranged from top to bottom; the soil sample placing layer, the circular mold falling layer and the sample protecting part rotating layer are cylindrical, and the diameters sequentially reduce; the sample protecting part rotating layer is rotationally arranged in the rotating groove; the diameter of the soil sample placing layer is equal to that of a soil sample; two or more than two sample protecting part pillars are arranged on the upper surface of the sample protecting part rotating layer; the protective part comprises a gasket arranged at the top of each of the sample protecting part pillars, a through hole for the corresponding sample protecting part pillar to be inserted in and a needle hole for the mold pressing needle to be inserted in are formed in the gasket, and the position of the needle hole is corresponding to that of a circular mold on the surface of the soil sample in the vertical direction. The demolding device provided by the invention has the benefits that the damage to the soil sample is less, the experimental period is shortened, and the efficiency is high.
Description
technical field [0001] The invention belongs to the field of civil engineering mechanics test instruments, in particular to a soil sample stripper for triaxial compression tests. Background technique [0002] In the triaxial test method, manual demoulding is generally used for soil sample demoulding, and the operation method is generally as follows: After compacting the soil body in the sample hammer, remove the soil sample, take off the collar with a sleeve, and separate the top and bottom of the soil sample. Put the impermeable stone on it, put it to a certain height, place the jammed knife on the round mold, and hit the round mold with a small hammer to demould. In this process, the operation is cumbersome, and the soil sample needs to be remade due to excessive human participation, which easily destroys the soil sample, which increases the experimental cycle and requires a new simple instrument to replace it. Contents of the invention [0003] In view of this, the pre...
