Description

Technical Field

[0001] This utility model relates to the field of grouting technology, specifically a modular visualization multi-material grouting test device. Background Technology

[0002] In the field of tunnel and underground engineering, grouting technology plays a crucial role as a key construction technique. It not only effectively reinforces the strata and controls strata deformation but also effectively prevents groundwater leakage, thereby ensuring the safety and quality of tunnel and underground engineering construction. However, with the continuous deepening and development of engineering practice, the requirements for grouting technology are becoming increasingly stringent. Especially under complex and variable geological conditions, how to scientifically and rationally select grouting materials and optimize grouting parameters to achieve the best grouting effect has become a current research hotspot and challenge in this field.

[0003] To delve deeper into the grouting mechanism, comprehensively evaluate the adaptability of different grouting materials to surrounding rock, and further optimize grouting parameters, researchers and engineers urgently need a comprehensive and high-performance testing device. This device should be able to simulate various surrounding rock conditions and support comparative tests of multiple grouting materials to meet the needs of scientific research and engineering practice.

[0004] However, existing grouting test equipment has many shortcomings:

[0005] 1. Uniqueness and limitations:

[0006] Most existing devices only support testing under single surrounding rock conditions or using a single grouting material.

[0007] The inability to fully assess the adaptability of different grouting materials to various surrounding rocks greatly limits their application scope and effectiveness under complex geological conditions.

[0008] 2. Poor modularity and scalability:

[0009] Existing devices often lack a modular design concept in terms of structural design and functional configuration, making it difficult to achieve flexible combination and expansion between modules.

[0010] This limits the adaptability and flexibility of the device in different application scenarios, and makes it unable to meet diverse and personalized testing needs.

[0011] 3. Low level of visualization:

[0012] Although some devices have certain visualization functions, they can often only make local observations and cannot reflect the grout diffusion and formation deformation during the grouting process in real time and comprehensively.

[0013] This limitation affects the accuracy and reliability of the experimental results, making it impossible to provide sufficient and robust data support for theoretical research and engineering practice.

[0014] In summary, existing grouting test devices have significant shortcomings in terms of functionality, adaptability, and visualization, failing to meet the current needs of in-depth research and widespread application of grouting technology in the tunnel and underground engineering field. Therefore, developing a new test device capable of simulating various surrounding rock conditions, supporting comparative tests of various grouting materials, and possessing highly visualized characteristics is particularly important and urgent.

[0023] Preferably, the output end of the grouting container is connected to a grouting pipe, and the output end of the grouting pipe extends into the input end of the surrounding rock container module.

[0024] Furthermore, a pressure detection element and a driving element are installed on the grouting pipe; wherein the pressure detection element is a pressure sensor, which is installed inside the grouting pipe; the driving element is a pressure regulating valve, and the control terminals of the pressure regulating valve and the pressure sensor are connected to the control cabinet.

[0025] Furthermore, the grouting container is equipped with a mixer.

[0027] Compared with the prior art, the present invention has the following beneficial technical effects:

[0028] This invention provides a modular, visualized multi-material grouting test device. Through the design of surrounding rock container modules and grouting unit groups, a high degree of modularity is achieved, allowing users to flexibly adjust the number of surrounding rock container modules and grouting containers according to experimental needs, thereby meeting the requirements of grouting tests of different scales and complexities. The grouting unit group contains multiple grouting containers, each capable of loading different grouting materials, enabling the testing of the effects of multiple grouting materials in the same experiment, greatly improving experimental efficiency and the convenience of data comparison. Each grouting container is equipped with pressure detection and driving components, allowing real-time monitoring of pressure changes during the grouting process and precise control via a control cabinet, ensuring the stability and safety of the grouting process while improving the accuracy of experimental data. Several surrounding rock container modules are respectively equipped with observation units, allowing experimenters to visually observe the diffusion and solidification process of the grouting material in the surrounding rock.

[0029] Furthermore, by combining multiple fan-shaped cavity containers into a ring-shaped container structure, multiple grouting tests can be conducted simultaneously, greatly improving experimental efficiency. Simultaneously, since each container module has an equal volume, consistency of test conditions is ensured, facilitating data comparison and analysis. The grouting containers are distributed at the center of the ring-shaped container structure, ensuring that the grouting material is uniformly injected into each surrounding rock container module. This design helps evaluate the diffusion and solidification performance of grouting materials under complex geological conditions, providing a basis for the selection and optimization of grouting materials.

[0030] Furthermore, the transparent glass material allows researchers to directly observe the diffusion, infiltration, and solidification processes of the grouting material within the surrounding rock container module. This visualization not only helps in gaining a deeper understanding of the grouting material's performance but also enables the timely identification of problems during experiments, improving their accuracy and reliability. Through visualization, researchers can more accurately record the state changes of the grouting material at different time points, thereby obtaining more precise experimental data.

[0031] Furthermore, the camera can monitor the grouting process within the surrounding rock container module in real time, particularly for abnormalities in the grouting material, such as leaks, blockages, or uneven solidification. This real-time monitoring capability helps researchers promptly identify and address potential problems, ensuring the smooth progress of the experiment. The camera's high-resolution lens can clearly capture subtle changes in the grouting material within the surrounding rock container module, providing researchers with high-precision experimental records. These records can be used for subsequent data analysis and research, contributing to a deeper understanding of the grouting material's performance and behavior.

[0032] Furthermore, the pressure sensor can monitor pressure changes within the grouting pipe in real time, ensuring that the grouting process is carried out within a safe pressure range. This real-time monitoring capability helps prevent grouting failure or equipment damage due to excessively high or low pressure. The pressure regulating valve can precisely adjust the pressure within the grouting pipe based on the feedback signal from the pressure sensor. This precise control capability helps ensure that the grouting material is injected into the surrounding rock container module at a constant pressure, thereby improving grouting efficiency and material utilization.

[0033] Furthermore, through the high integration of components such as the controller, signal receiving module, and signal output module, automated control of the grouting test device has been achieved. Experimenters only need to set relevant parameters on the control cabinet, and the system can automatically complete the monitoring, data collection, analysis, and drive control of the grouting process, greatly improving the efficiency and accuracy of the experiment.
