Problems solved by technology

At present, there are few mechanical testing devices for the entire waste tire reinforced soil and the waste tire-soil interface, and most of them intercept a certain tire piece for shearing test, which is far from the actual application situation, and it is bound to fail to reflect the whole waste tire. Shear Mechanical Properties of Tire-Soil Cylinder
[0004] Some researchers have further developed a mechanical testing device that can involve the entire tire interface. However, due to the limited function of the device itself, only the shear test of the horizontal interface can be realized, and neither the shear test of the vertical interface nor the horizontal interface can be realized. The test of the influence of earth pressure on the mechanical properties of the reinforcement-soil vertical interface at different depths is not applicable to the test of the interface mechanical properties of different sizes (tire diameter and tread height, etc.)

Embodiment

[0036] see figure 1 with figure 2 , a waste tire-soil vertical interface shear characteristic testing device, including a sample system, a confining pressure loading system, a servo control system and a data acquisition system.

[0037]The sample system includes waste tires 9 , an actuating platform base 11 and an actuating platform top cover 13 . The waste tire 9 is arranged horizontally, the top cover 13 and the base 11 of the actuator are opposite up and down and are located on the lower surface and the upper surface of the waste tire 9 respectively, and the base 11 and the top cover of the actuator are 13 are all in close contact with the surface of waste tires, and soil sample II 10 is uniformly filled inside the waste tires 9 . The actuating table in this application is divided into a base and a top cover structure that can act independently, which can meet the testing requirements of waste tires with different tread widths.

[0038] In this embodiment, the diameters...

Abstract

The invention discloses a waste tire-soil vertical interface shear characteristic testing device which comprises a sample system, a confining pressure loading system and a servo control system, the sample system comprises an actuating table top cover, an actuating table base and a waste tire horizontally arranged between the actuating table top cover and the actuating table base, the actuating table top cover and the actuating table base are oppositely arranged up and down, and the waste tire is uniformly filled with a soil sample II; the confining pressure loading system comprises an annular shearing box arranged on the radial outer side of the sample system as well as a confining pressure air bag and a soil sample I which are sequentially filled in the annular shearing box from outside to inside in the radial direction, the soil sample I is in contact with the cylindrical side surface of the waste tire, and a horizontal load is provided through the confining pressure air bag; the servo control system is used for adjusting the height position of the sample system and providing a load in the vertical direction, a detachable base plate is arranged in the annular shear box, the sample system is connected with the displacement meter, and the servo control system is connected with the stress sensor. The device is suitable for carrying out shear test on the waste tire-soil vertical interface under the conditions of different burial depths and sizes.

Description

technical field [0001] The invention relates to the technical field of reinforced soil engineering, in particular to a testing device for the shear characteristic of the vertical interface between waste tires and soil. Background technique [0002] In recent years, with the continuous growth of automobile production, the number of waste tires that have been eliminated has also increased dramatically year by year. The accumulation of a large number of waste tires not only occupies land, but also pollutes the natural environment. Improper handling of them will bring serious environmental problems and harm The surrounding residents are in good health. Therefore, how to recycle waste tires scientifically, environmentally friendly, economically, safely and efficiently is a major practical problem to be solved urgently. At present, waste tires have been used in reinforced soil projects such as strengthening rock and soil slopes, retaining walls, embankments, and weak foundations ...
