Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of abandoned slag field simulation, and specifically relates to a kind of abandoned slag field indoor multi-scale triaxial test structure of rock-soil mass. BACKGROUND

[0002] As indispensable but extremely challenging artificial loose accumulation in mining, water conservancy construction and traffic engineering, the complex rock-soil structure of abandoned slag field shows high heterogeneity and multi-scale characteristics, which is reflected in the mixed distribution of large stone skeleton and fine-grained soil, making its mechanical properties not only complex and changeable, but also showing significant anisotropy. When encountering strong dynamic load such as earthquake, the stress distribution inside the abandoned slag field will change dramatically, and the interaction between particles may be unstable due to sliding, and even liquefaction phenomenon may occur. These factors together can easily trigger large-scale sliding or collapse events, posing a major threat to surrounding infrastructure and seriously threatening the safety of personnel. In the face of the increasing frequency of seismic activity worldwide, it has become a key scientific problem in the field of geotechnical engineering to deeply explore the response mechanism and failure mechanism of abandoned slag field under earthquake.

[0003] However, the current technical means are limited in simulating the seismic behavior of abandoned slag field, and the traditional test method mostly relies on single-direction vibration loading on the bottom of rock-soil by vibration motor or electromagnetic exciter. This simplified loading mode cannot fully simulate the multi-component coupling effect of seismic wave, including horizontal and vertical composite vibration, and cannot accurately reproduce the comprehensive influence of complex waveform characteristics such as P wave (longitudinal wave) and S wave (transverse wave) in actual seismic motion on the rock-soil of abandoned slag field, which directly leads to significant differences between laboratory test results and actual observed damage patterns, greatly limiting the in-depth study of seismic response characteristics of abandoned slag field.

[0004] Therefore, the inventor proposes an indoor multi-scale triaxial test structure of rock-soil mass in abandoned slag field to solve the above technical problems. UTILITY MODEL CONTENT

[0005] The utility model aims to provide an indoor multi-scale triaxial test structure of rock-soil mass in abandoned slag field to solve the problem of single seismic behavior loading mode and difficulty in reflecting the influence of multi-component coupling effect of seismic wave in the simulation test of rock-soil mass in abandoned slag field of prior art.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0007] A multi-scale triaxial test structure for soil and rock mass in a spoil disposal site includes at least one oscillating seat, a platform, and a soil and rock box. Each of the oscillating seats is disposed at the bottom of the platform, and the soil and rock box is detachably installed on the platform.

[0008] The vibration seat includes a base plate, two support plates, a first movable seat and a second movable seat. The two support plates are fixedly mounted on the base plate. The first movable seat has a first guide rod on both sides. The first guide rod is slidably connected to the support plate. The first movable seat can move along the length of the base plate.

[0009] The second movable seat is provided with a second guide rod, and the second movable seat is slidably connected to the second guide rod;

[0010] The second movable seat has a drive hole, and the top of the second movable seat has a top plate.

[0011] It also includes a driving component that extends into the driving hole to drive the second movable seat to move.

[0012] Furthermore, the driving component includes a motor, a turntable, and a driving rod. The output shaft of the motor is coaxially connected to the turntable, and the driving rod is eccentrically connected to the turntable, extending into the driving hole.

[0013] Furthermore, a first connecting clip is provided at the bottom of the first movable seat, the first connecting clip is located between the two support plates, and a first tension spring is provided between the first connecting clip and the support plate.

[0014] Furthermore, the second movable seat is provided with second connecting clips on both sides, the first movable seat is provided with a third connecting clip, and a second tension spring is provided between the second connecting clip and the third connecting clip.

[0015] According to the above technical solution, by setting a first tension spring and a second tension spring, elastic reset and multi-directional dynamic balance can be achieved during vibration loading. The first tension spring connects the first movable seat and the support plate, providing a reverse rebound force during horizontal vibration, suppressing excessive vibration offset and reducing mechanical impact. The second tension spring is connected in series with the first and second movable seats to form a coupling buffer mechanism for vertical movement, which not only coordinates the synchronicity of the composite vibration direction conversion, but also absorbs the excess energy generated by high-frequency vibration. The synergistic effect of the two enhances the stability and controllability of the system motion, ensures the accurate reproduction of multi-component coupled loading of seismic waves, and effectively extends the service life of the structure.

[0016] Furthermore, the platform includes a platform and two support platforms, the platform being connected to the top plate, and the two support platforms being symmetrically arranged on the platform;

[0018] First bevel gears are arranged on the two rotating shafts, and second bevel gears are arranged on the connecting shaft, and the first bevel gears are engaged with the second bevel gears.

[0019] According to the above technical solution, the rotating shafts of the two support tables are connected through the connecting shaft, the first bevel gears on the rotating shafts are vertically engaged with the second bevel gears on the connecting shaft, forming a 90-degree power steering transmission chain, when the motor drives any rotating shaft to rotate, the first bevel gear transmits torque to the second bevel gear, forcing the connecting shaft to rotate in the opposite direction, and then driving the other rotating shaft to rotate in the opposite direction synchronously, the structure forcibly maintains the symmetrical motion of the two shafts with a phase difference of 180° through the engagement of the bevel gears, thereby maintaining the transmission during the composite vibration loading process.

[0020] Further, a driving gear is coaxially and fixedly connected to the output shaft of the motor, a driven gear is coaxially and fixedly connected to one of the rotating shafts, and a synchronous belt is arranged between the driving gear and the driven gear.

[0021] According to the above technical solution, the motor rotates to drive the driving gear to rotate, the driving gear drives the driven gear to rotate through the synchronous belt, and then drives the cam on the driving shaft to rotate, for simulating the vibration of the rock-soil box.

[0022] Further, the platform comprises a vibration plate, guide grooves are formed on both sides of the vibration plate, guide blocks are arranged on the two support tables, the guide blocks extend into the guide grooves, and the vibration plate can move up and down along the height direction of the platform.

[0023] Further, contact strips are arranged on both sides of the vibration plate, a plurality of cams are arranged on the two rotating shafts, and the cams periodically contact the contact strips.

[0024] According to the above technical solution, when the rotating shaft rotates, the cam periodically presses the contact strips on both sides of the vibration plate, forcing the vibration plate to vertically rise along the guide groove, and when the cam is disengaged, the vibration plate falls under the action of gravity, forming periodic up-down vibration, the guide blocks and the guide grooves are designed to be embedded, so that the vibration plate can only move along the vertical direction, preventing horizontal deviation; at the same time, the depth of the guide groove and the limiting of the guide block form a mechanical lock, which prevents the vibration plate from being separated from the support table during severe vibration, ensuring the stability of vibration transmission and test safety.

[0025] Further, a receiving cavity is formed in the rock-soil box, and the receiving cavity is used for placing rock-soil bodies.

[0026] The rock-soil box is of a transparent structure.

[0027] Further, a top of the rock-soil box is provided with a spraying plate;

[0028] The spraying plate comprises a plate body and a water pipe, the plate body is provided with a spraying cavity and a plurality of spray holes communicated with the spraying cavity, the water pipe is installed on the top of the plate body, and the water pipe is communicated with the spraying cavity.

[0029] According to the technical scheme, the transparent box body facilitates researchers to observe the particle migration, crack expansion and other mesoscopic failure processes of the rock-soil body in the containing cavity under the vibration load in real time; the spraying plate at the top injects water into the spraying cavity through the water pipe, the water is uniformly distributed in the plate body, and then is sprayed through the spray holes to form uniform atomization, so that the water erosion effect of the rock-soil body caused by the rainfall infiltration or the change of the underground water level is accurately simulated, the combined structure meets the vibration loading and water-force coupling environment simulation requirements, and provides visual test conditions for studying the instability mechanism of the waste dump under the combined action of the seepage and vibration.
