Description

Technical Field

[0001] The invention belongs to the technical field of rock, soil and dynamic water grouting, and particularly relates to a multifunctional visual three-dimensional grouting effect test box and a use method thereof. Background Art

[0002] With the continuous development of cities and international infrastructure, the requirements for civil engineering are constantly increasing. Tunnels, underground spaces, and large foundation pits inevitably encounter hazards such as sudden mud and water inrush during construction, necessitating the use of indoor grouting simulation to address these practical engineering challenges. However, existing grouting simulation equipment is mostly unilateral and only targets a single scenario. However, the engineering geology in actual projects is extremely complex, with diverse conditions such as no water, static water, dynamic water, and varying rock and soil distribution and particle size. Existing equipment struggles to meet these requirements.

[0003] For dynamic water grouting, most of the existing grouting simulation equipment simulates the movement of slurry under dynamic water conditions. Although this can effectively analyze the diffusion of slurry under dynamic water conditions, it does not simulate the actual situation that the slurry must move to a specific rock and soil mass. The movement and diffusion range of the slurry in the rock and soil mass under dynamic water conditions and grouting pressure are the top priorities of grouting simulation.

[0004] For compaction grouting, the rock and soil mass moves around under the action of grouting pressure, but the influence range of compaction pressure under specific grouting pressure conditions and the specific relationship between grouting pressure and soil compaction are unclear.

[0020] Preferably, the compaction grouting movement baffle is made of light steel sheets, and the bottom plate and the side plates are made of steel plates.

After the grouting is completed, the diffusion range of the slurry in the water injection part of the grouting box is mainly observed, the mechanical properties of the stone body are analyzed by drilling core, and the diffusion range of the slurry in the rock-soil body under different dynamic water dilution conditions is analyzed combined with test 1, and the grouting effect is comprehensively analyzed.

[0056] Test 3. Water-free environment, ordinary soil grouting simulation

[0058] The specific steps are: filling the test material in the test main box body according to the required proportion, closing the water injection port I 2 and the water injection port II 3, then carrying out pressure grouting through the grouting port 1, analyzing the diffusion range of the slurry through the soil pressure gauges and pore pressure sensors installed in the rock-soil body, judging the grouting effect, and analyzing the mechanical properties of the stone body through drilling core, and then analyzing the grouting effect and the grouting performance of the slurry.

[0059] Test 4. Static water environment, ordinary soil grouting simulation

[0060] The test main box body is adopted. Figure 1 The test main box body is connected with the measurement equipment, the grouting equipment and the water supply equipment.

[0061] The specific steps are as follows: fill the test box with test materials according to the required proportions, inject water through water injection ports I2 and II3, and close water injection ports I2 and II3 when the soil in the test box reaches the corresponding moisture content. Then, pressure grouting is carried out through grouting port 1. The slurry diffusion range is analyzed using earth pressure gauges and pore pressure sensors installed in the rock and soil to determine the grouting effect. At the same time, core drilling is performed to analyze the mechanical properties of the stone body, and then the grouting effect and slurry grouting performance are analyzed.

Then, grouting is carried out through grouting port 1. The compaction grouting motion baffle 8 moves along the baffle motion groove 18 under the pressure generated by soil compaction, squeezing the soil outside the compaction grouting motion baffle 8. By measuring the pressure on the compaction grouting motion baffle 8 and the pressure and strain in the rock and soil inside and outside the compaction grouting motion baffle 8, the compaction conditions, compaction impact range, and the undulating shape of the rock and soil of different soils and different pressures are analyzed.

[0068] Test 7. Hydrostatic environment, compaction grouting simulation

[0069] use Figure 10 The compaction grouting model is connected to the measuring equipment and the grouting equipment.

[0070] The specific steps are as follows: installing the compaction grouting simulation device in the test main box, filling the test rock-soil body in the test main box according to the proportion, and burying the pressure gauge and the pore pressure sensor in the rock-soil body to measure and record the data. The water in the rock-soil body inside the baffle is injected through the grouting port 1, and the water content of the rock-soil body outside the fixed compaction grouting movement baffle 8 is adjusted by injecting water through the water injection port I 2 and the water injection port II 3. When the water content of the soil inside and outside the fixed compaction grouting movement baffle 8 reaches the corresponding value, the water injection port I 2 and the water injection port II 3 are closed, and then the grouting is carried out through the grouting port 1. The fixed compaction grouting movement baffle 8 moves along the baffle movement groove 18 under the pressure formed by the compaction of the soil, and forms extrusion on the soil outside the fixed compaction grouting movement baffle 8. By measuring the pressure on the fixed compaction grouting movement baffle 8, the internal pressure and strain of the rock-soil body inside and outside the fixed compaction grouting movement baffle 8, the diffusion range of the slurry under different soil and pressure, the compaction condition, the compaction influence range, and the surface shape of the rock-soil body are analyzed.

[0071] From the above seven different grouting conditions, it can be seen that the device can simulate grouting under various conditions, which is more suitable for engineering practice. By observing and recording data, the grouting performance of the slurry is analyzed under different grouting forms under the conditions of no water, static water and dynamic water. The flow performance of the slurry is analyzed by dynamic water grouting, and the diffusion range and grouting effect of the slurry under dynamic water dilution condition are analyzed by dynamic water rock-soil grouting. The grouting principle of compaction is analyzed by simulating the compaction grouting under the conditions of no water and static water. Therefore, the device is very suitable for engineering practice, which can not only comprehensively analyze the basic performance of the slurry, but also analyze the performance of the same slurry under different pressures, different geological environments and different hydraulic conditions. Moreover, the dynamic water grouting and dynamic water rock-soil grouting and compaction grouting further supplement the grouting theory.
