Embodiment 1

[0023] Such as Figure 1-6 As shown, an anti-interference shrinkage test device consists of a column brace (1), a vertical gauge (2), a beam (3), a limit collar (4), a vertical deformation measuring plate (5), a level, a measuring Table support (7), level gauge (8), perforated plate (9), spacer (10), base (11), rubber gasket (12), flat electronic scale (13), electronic scale level adjustment knob (14), the horizontal deformation measuring plate (15) is formed, except that the material of the base (11) is a hard plastic plate, the materials of other devices are all stainless steel; during the test, the column strut (1), the vertical scale ( 2), the beam (3), the limit collar (4) and the vertical deformation measuring plate (5) form a vertical deformation measurement device to measure the vertical shrinkage deformation of the sample; the horizontal gauge support (7) and horizontal gauge (8) form horizontal deformation measuring device; described panel electronic scale (13) and ...

Embodiment 2

[0025] Such as Figure 1-6 As shown, when carrying out the shrinkage test, at first the flat electronic scale (13) is kept level by the electronic scale level adjustment knob (14), and then the porous plate (9) with the groove is placed on a height of 11.5 mm and a radius of 1.5mm spacer (10), and insert the spacer into the groove of the perforated plate (9), place a cross-shaped measuring plate (5) with a wing width of 6mm on the top of the sample, and the thimble of the vertical gauge (2) against the At the center of the cross-shaped measuring board (5), the vertical meter (2) is connected with the column strut (1) through the beam (3), and the beam (3) and the column strut (1) will be further passed through after the preliminary connection The limit collar (4) limits the sliding of the beam (3). The level gauge (8) is connected to the base (11) through the support (7), and the connecting detail of the base (11) and the support (7) is a bolt combination structure, which can...

Embodiment 3

[0027] Such as Figure 2-7 As shown, if the test only needs to measure the vertical deformation, you can unscrew the nuts of the two horizontal scale supports (7) on either side of the base, and place the two supports (7) along the base (11) respectively. Move out the groove position to the left and right sides of the test instrument, then according to the relevant steps described in Example 2, operate in the order of the perforated plate (9), sample (6), and cross-shaped measuring plate (5), and finally Install the vertical meter (2) and adjust the measuring range, then keep the tablet electronic scale (13) level by the electronic scale level adjustment knob (14), and finally place the whole device on the tablet electronic scale (13), and start the test.

Abstract

The invention discloses a novel anti-disturbance shrinkage test device. The device comprises a mass measuring device and a deformation measuring device; the deformation measuring device is composed ofthree gauges, a perforated plate, a bracket, a measuring plate, spacers and a base, wherein two gauges are fixed on the base, and the other one gauge is mounted on the bracket; the mass measuring device is a flat electronic scale the precision of which reaches 0.01 g, and the deformation measuring device is placed on the mass measuring device. The novel anti-disturbance shrinkage test device cancollect the moisture content and volume parameters of a test sample in a shrinkage test in real time; the effect of resisting external-force disturbance is achieved through the anti-vibration rubber spacers, the perforated plate with a groove and the novel connection bracket, and therefore the test has high measuring precision. The device is simple in structure, easy to operate and very convenientto assemble and disassemble.

Description

Technical field: [0001] The invention relates to an anti-disturbance shrinkage test device in the field of civil engineering tests. Background technique: [0002] Soil is a kind of scattered particle accumulation covering the surface. Its main physical properties are very different from other materials such as metal materials, especially expansive soil, which is a special soil body. The characteristic is a problem that the engineering community has to pay attention to. Under this characteristic, the expansion and contraction deformation of the soil may cause problems such as uneven settlement of the upper foundation, cracking of the slope soil, and a reduction in the bearing capacity of the foundation. Therefore, how to accurately measure the soil It is of great practical significance to measure the expansion and contraction characteristics of the material and effectively deal with the characteristics. Shrinkage test is designed to determine the shrinkage characteristics of...
