Description

Technical Field

[0001] The invention relates to the technical field of experimental simulation, in particular to an experimental simulation device for core fracture penetration grouting filling samples. Background Art

[0002] Core fracture penetration grouting involves injecting a slurry into the fissures of a rock mass under pressure. Through penetration and diffusion, the slurry fills the fissures and displaces the water and gas trapped within, thereby strengthening the rock mass and improving its anti-seepage properties. This technology is widely used in tunnels, mines, water conservancy projects, and underground construction. It strengthens rock mass, improves anti-seepage properties, and reduces groundwater leakage and inrush.

[0032] See also Figures 1 to 8 The present invention provides an experimental simulation device for core fracture penetration grouting filling sample, comprising:

[0033] The core sample preparation component 1 is arranged in a straight slot shape, with a regular sample input belt 2 and a rock sample mixer 3 fixedly arranged on the outer side of one semicircular side, and a grouting simulation component 11 arranged above the middle of the other semicircular side;

[0034] The core sample preparation component 1 is provided with a hydraulic cutter device 4, a hot and cold seam making device 5 and a cleaning tank 7 in sequence above the straight side close to the regular sample input belt 2 from the regular sample input belt 2 to the grouting simulation component 11, and a dripping mechanical arm 6 is provided between the hot and cold seam making device 5 and the cleaning tank 7. The dripping mechanical arm 6 is provided outside the core sample preparation component 1 and is connected to a chemical solvent tank 12.

[0035] The core sample preparation component 1 is provided with a high temperature vaporization chamber 10 and a cleaning tank 7 in sequence from the rock sample mixer 3 to the grouting simulation component 11 on the straight side near the rock sample mixer 3. The high temperature vaporization chamber 10 and the rock sample mixer 3 are provided with two sets of display racks 8. The two sets of display racks 8 are provided outside the core sample preparation component 1, and a clamping and inserting mechanical arm 9 is provided between the two sets of display racks 8.

[0036] As a preferred embodiment, the device needs to determine the state of the core sample in advance. If there is a complete core sample, it will be cut and trimmed into a rectangular parallelepiped with a flat side and meeting the requirements. If there is no complete core sample, the mortar material that meets the requirements will be injected into the core sample making component 1 for molding and making, so that the device can meet the production work of core samples under different circumstances, and thus better carry out simulation experiments. Because the width, length, depth, direction and inclination of the core cracks can affect the penetration and diffusion of the slurry, thereby affecting the experimental results, the device is equipped with a hydraulic cutter device 4, a hot and cold seam making device 5, a dripping robot arm 6 and a chemical solvent tank 12, a display rack 8 and a clamping and inserting machine. The mechanical arm 9 and the high-temperature vaporization chamber 10 are used to manufacture different cracks, thereby simulating the actual rock crack conditions to the greatest extent and improving the authenticity and accuracy of the experimental simulation. At the same time, the setting of the core sample making component 1 can carry the core sample and adjust the position of the core sample so that it can carry out the crack manufacturing work. After the crack manufacturing is completed, the grouting simulation component 11 is used to carry out the experimental simulation. After the simulation is completed, the core sample making component 1 is cleaned by the corresponding cleaning tank 7 so that it can continue to participate in subsequent work. Through the coordination of various components, the device can automatically complete the core crack manufacturing work according to requirements, and carry out experimental simulation after completion, thereby further improving the experimental efficiency.

[0037] Furthermore, zinc sheets of different orientations, shapes, and widths are placed on the racks 8 near the rock sample mixer 3, and steel sheets of different widths are placed on another set of racks 8;

[0038] As a preferred embodiment, the zinc sheet and the steel sheet can simulate the crack position of the core as much as possible, and the zinc sheet can be vaporized at high temperature to leave cracks in the core, while the steel sheet leaves cracks by being inserted and withdrawn.

[0040] As a preferred embodiment, the hydraulic carving knife device 4 uses hydraulic pressure to push the carving knife to create cracks on the core, and can accurately control the position and shape of the cracks. The hot and cold cracking device 5 uses the heterogeneity of thermal expansion of rock mineral components to heat the core at high temperature and then quickly cool it, thereby generating cracks in the core. The dripping robot arm 6 uses chemical solvents such as inorganic acids in the chemical solvent tank 12 to dissolve specific mineral components in the rock, thereby forming cracks in the core. The cut core sample will be input into the core sample production component 1 under the action of the regular sample input belt 2. The core sample production component 1 will rotate clockwise so that it passes through the hydraulic carving knife device 4, the hot and cold cracking device 5, and the dripping robot arm 6 in turn, and selects a suitable cracking method according to actual conditions to form cracks. Then, the experimental simulation is completed under the action of the grouting simulation component 11, and then it is cleaned by the corresponding cleaning tank 7 to prevent the residual material on the core sample production component 1 from affecting the experimental simulation of other cores.

According to needs, steel sheets or zinc sheets are selectively inserted through the clamping and insertion robot arm 9. After the sample is initially solidified, the steel sheets are extracted through the clamping and insertion robot arm 9, or the zinc sheets inside the sample are vaporized through the high-temperature vaporization chamber 10. Artificial rock samples with different geometric shapes and connectivity can be produced for subsequent experimental simulations, and then the experimental simulation is completed under the action of the grouting simulation component 11, and then cleaned through the corresponding cleaning tank 7.

[0043] Furthermore, the core sample preparation assembly 1 includes a support frame 13, wherein the support frame 13 is linearly arranged in multiple groups, and the inner side of the support frame 13 is fixedly assembled with two groups of horizontally arranged equally spaced rotating drive rings 14, and an elastic conveyor belt 15 is rotatably arranged between the two groups of rotating drive rings 14, and the elastic conveyor belt 15 is cut with eleven groups of through holes, and a rock sample supporting shell 16 is vertically fixedly assembled in each group of through holes, and a rock sample displacement assembly 17 is horizontally slidably arranged on both sides of each group of rock sample supporting shells 16 in the running direction;

It can adjust the actual height of the core sample according to demand, so as to better perform the seam-making work. The setting of the rotating drive ring 14 can drive the elastic conveyor belt 15 to rotate, and because of the elastic properties of the elastic conveyor belt 15, it can complete the change of the straight segment to the curved segment of the rotating drive ring 14 through deformation, and the through hole set on the elastic conveyor belt 15 will not deform. It will always be fixedly embedded with a group of rock sample carrying shells 16, and the rock sample displacement component 17 can assist the rock sample in changing its position, so as to better and more realistically perform the crack-making work.

[0045] Furthermore, the rock sample carrying shell 16 includes a fixed frame 18. An automatic opening and closing door 21 is rotatably provided on the upper end of the fixed frame 18 near the outer ring of the core sample preparation assembly 1.

[0047] As a preferred embodiment, the setting of the automatic opening and closing door 21 facilitates the removal and placement of core samples, thereby completing the automated loading and unloading work better and more conveniently. The setting of the lifter 20 pushes the core sample on the piston plate 19 machine to rise or fall, thereby facilitating the position adjustment of the rock sample displacement component 17.

[0048] Furthermore, the rock sample displacement assembly 17 includes a sliding bracket 22, and the sliding bracket 22 is provided in two groups in a mirror image.

[0049] As a preferred embodiment, when the lifter 20 lifts the core sample to a certain height (higher than the fixed frame 18), the sliding bracket 22 will drive the rock sample displacement assembly 17 to rise to a certain height (the central axis of the first hydraulic cylinder 25 is on the middle horizontal plane of the core sample), and then the two opposite groups of first hydraulic cylinders 25 will extend, so that the two groups of fixed clamping suction cups 26 thereon will clamp the rock sample, and the rock sample will be rotated under the action of the driving motor 23 thereon, so that it can achieve the purpose of position adjustment, and then cracks on different surfaces can be manufactured, so that the cracks of the laboratory samples are more realistic and accurate, further improving the accuracy of the experimental simulation.

[0051] Furthermore, an elastic sealing gasket is provided on the outside of the closed piston plate 30, and the sealing gasket and the rock sample carrying shell 16 can form a closed simulation chamber;

[0052] As a preferred embodiment, the provision of the elastic sealing pads around the piston plate 19 and the closed piston plate 30 can minimize the gaps between the piston plate 19 and the closed piston plate 30 and the side closing plates of the fixed frame 18, thereby forming a relatively closed simulation chamber, so that the experiment can exclude the influence of external environmental factors, and under the influence of the pressure-controlled motor and the slurry tank, the variables can be well controlled to explore the permeability of core fractures under different conditions, so that by reasonably selecting grouting materials and grouting process parameters, and strictly controlling the grouting construction process, good reinforcement and anti-seepage effects can be achieved.

[0054] As a preferred embodiment, the setting of the constant temperature chamber can keep all components in the device at a constant temperature to prevent temperature changes from affecting the properties of the grouting material, such as viscosity and setting time. High temperatures may accelerate the curing process of the grouting material, while low temperatures may reduce its fluidity.

Cracks on different surfaces are created, and then the experimental simulation is completed under the action of the grouting simulation component 11, and then it is cleaned by the corresponding cleaning tank 7. After it is rotated to its initial position, a set of rock sample carrier shells 16 are completed.
