Hydraulic jacking detection in high-pressure rock mass grouting is an important aspect to ensure the effectiveness and safety of the grouting process. Here is an overview of how to implement hydraulic jack detection using a hydraulic pump: 1. Pressure monitoring: Hydraulic jacking detection involves pressure monitoring in the grouting process. Pressure transducers or transducers are installed in hydraulic circuits, usually near grout nozzles or at strategic points in the system. The pressure transducer measures the pressure exerted by the hydraulic pump on the grout material. 2. Pressure limit setting: According to the specific requirements of the grouting project and the nature of the rock mass to be processed, set the predetermined pressure limit. This pressure limit acts as a threshold beyond which hydraulic jacking may occur. Careful setting of the pressure limit is critical to avoid applying excessive force to the rock mass, which could lead to unintended consequences such as fracture or instability. 3. Real-time monitoring: When the hydraulic pump transports the grouting material, the pressure sensor continuously monitors the pressure in real time. Pressure readings are transmitted to a control system or monitoring device. 90-L-250-HS-5-EG-80-T-4-C8-J-03-NNN-23-23-24 90L250HS5EG80T4C8J03NNN232324 90L250-HS-5-EG-80-T-4-C8-J-03-NNN-23-23-24 90L250HS5EG80T4C8J03NNN232324 90-L-250-HS-5-EF-80-T-3-C8-K-03-NNN-42-42-28 90L250HS5EF80T3C8K03NNN424228 90L250-HS-5-EF-80-T-3-C8-K-03-NNN-42-42-28 90L250HS5EF80T3C8K03NNN424228 90-L-250-HS-5-CD-80-T-3-C8-K-03-NNN-42-42-28 90L250HS5CD80T3C8K03NNN424228 90L250-HS-5-CD-80-T-3-C8-K-03-NNN-42-42-28 90L250HS5CD80T3C8K03NNN424228 90-L-250-HS-5-BC-80-S-4-F1-K-03-NNN-42-42-24 90L250HS5BC80S4F1K03NNN424224 90-L-250-HS-5-AB-80-T-4-F1-J-03-NNN-45-42-24 90L250HS5AB80T4F1J03NNN454224 90L250-HS-5-AB-80-T-4-F1-J-03-NNN-45-42-24 90L250HS5AB80T4F1J03NNN454224 90-L-250-HS-1-CD-80-T-4-F1-J-05-NNN-42-42-24-F001 90L250HS1CD80T4F1J05NNN424224F001 90-L-250-HS-1-CD-80-S-3-F1-J-03-NNN-35-35-28 90L250HS1CD80S3F1J03NNN353528 90-L-250-HS-1-BC-80-T-4-C8-K-03-NNN-23-23-26 90L250HS1BC80T4C8K03NNN232326 90L250-HS-1-BC-80-T-4-C8-K-03-NNN-23-23-26 90L250HS1BC80T4C8K03NNN232326 90-L-250-HF-5-NN-80-T-4-F1-K-03-NNN-42-42-24 90L250HF5NN80T4F1K03NNN424224 90L250-HF-5-NN-80-T-4-F1-K-03-NNN-42-42-24 90L250HF5NN80T4F1K03NNN424224 90-L-250-HF-5-NN-80-T-4-F1-K-03-NNN-35-35-28 90L250HF5NN80T4F1K03NNN353528 90L250-HF-5-NN-80-T-4-F1-K-03-NNN-35-35-28 90L250HF5NN80T4F1K03NNN353528 90-L-250-HF-5-NN-80-T-4-F1-K-03-NNN-35-35-24 90L250HF5NN80T4F1K03NNN353524 90L250-HF-5-NN-80-T-4-F1-K-03-NNN-35-35-24 90L250HF5NN80T4F1K03NNN353524 90-L-250-HF-5-NN-80-T-4-F1-K-03-NNN-21-21-24 90L250HF5NN80T4F1K03NNN212124 4. Pressure Comparison: Compare real-time pressure readings with predetermined pressure limits. If the pressure exceeds the set limit, it is an indication that hydraulic jacking may be occurring. This triggers an alarm or warning signal to alert the operator or supervisor monitoring the grouting process. 5. Operator Intervention: When hydraulic jacking is detected, the operator or supervisor must take appropriate action to mitigate the situation. This may involve adjusting grouting parameters, reducing pump flow, or temporarily stopping the grouting process to relieve pressure. 6. Evaluation and analysis: After the hydraulic jacking is detected, the grouting process and rock mass conditions should be comprehensively evaluated. This assessment helps determine the cause of the overstress and identifies any potential risks or adverse effects to the rock mass. Analysis may involve examining geological features, adjusting grouting methods, or implementing other measures to ensure the stability and effectiveness of the grouting process. 7. Data recording and analysis: In addition to real-time monitoring, it is also beneficial to record and record pressure data during the grouting process. This data can be analyzed after grouting to assess pressure distribution, identify any pressure peaks or unusual trends, and assess the effectiveness of the grouting operation. Data logging allows for a comprehensive analysis of the grouting process and can provide valuable insights for future grouting projects. 8. Redundancy and safety measures: In order to improve safety and reliability, it is recommended to add redundancy and safety measures to the hydraulic jacking detection system. This may include redundant pressure transducers for backup monitoring, pressure relief or bypass valves to relieve excess pressure, and emergency shutdown systems to stop grouting operations in critical pressure conditions. 90L250-HF-5-NN-80-T-4-F1-K-03-NNN-21-21-24 90L250HF5NN80T4F1K03NNN212124 90-L-250-HF-5-NN-80-T-4-F1-K-03-NNN-14-42-20 90L250HF5NN80T4F1K03NNN144220 90L250-HF-5-NN-80-T-4-F1-K-03-NNN-14-42-20 90L250HF5NN80T4F1K03NNN144220 90-L-250-HF-5-NN-80-T-3-F1-K-03-NNN-35-35-20 90L250HF5NN80T3F1K03NNN353520 90L250-HF-5-NN-80-T-3-F1-K-03-NNN-35-35-20 90L250HF5NN80T3F1K03NNN353520 90-L-250-HF-5-NN-80-T-3-F1-J-03-NNN-42-42-24 90L250HF5NN80T3F1J03NNN424224 90L250-HF-5-NN-80-T-3-F1-J-03-NNN-42-42-24 90L250HF5NN80T3F1J03NNN424224 90-L-250-HF-5-NN-80-S-4-C8-K-03-NNN-35-35-24 90L250HF5NN80S4C8K03NNN353524 90L250-HF-5-NN-80-S-4-C8-K-03-NNN-35-35-24 90L250HF5NN80S4C8K03NNN353524 90-L-250-HF-5-NN-80-S-3-C8-K-03-NNN-35-35-24 90L250HF5NN80S3C8K03NNN353524 90L250-HF-5-NN-80-S-3-C8-K-03-NNN-35-35-24 90L250HF5NN80S3C8K03NNN353524 90-L-250-HF-5-EG-80-T-4-C8-K-03-NNN-38-38-28 90L250HF5EG80T4C8K03NNN383828 90L250-HF-5-EG-80-T-4-C8-K-03-NNN-38-38-28 90L250HF5EG80T4C8K03NNN383828 90-L-250-HF-5-EF-80-S-4-C8-J-03-NNN-23-23-24 90L250HF5EF80S4C8J03NNN232324 90L250-HF-5-EF-80-S-4-C8-J-03-NNN-23-23-24 90L250HF5EF80S4C8J03NNN232324 90-L-250-HF-5-CD-80-T-3-C8-K-03-NNN-35-35-24 90L250HF5CD80T3C8K03NNN353524 90L250-HF-5-CD-80-T-3-C8-K-03-NNN-35-35-24 90L250HF5CD80T3C8K03NNN353524 90-L-250-HF-5-CD-80-S-3-F1-J-03-NNN-23-23-24 90L250HF5CD80S3F1J03NNN232324 90L250-HF-5-CD-80-S-3-F1-J-03-NNN-23-23-24 90L250HF5CD80S3F1J03NNN232324 90-L-250-HF-5-BC-80-T-4-F1-K-04-NNN-42-42-24 90L250HF5BC80T4F1K04NNN424224 9. Training and Operator Awareness: Proper training of operators and personnel involved in the grouting process is critical. They should be familiar with hydraulic jacking detection systems, understand the importance of pressure monitoring, and be trained to react and act appropriately when hydraulic jacking occurs. Operator awareness and vigilance facilitate early detection and timely intervention, minimizing potential risks. 10. Continuous Improvement: Hydraulic jacking inspections should be part of the continuous improvement process for grouting operations. Lessons learned from previous projects, data analysis, and operator feedback should be used to refine grouting methods, optimize pressure limits, and enhance safety practices. Regular reviews and updates to the hydraulic jack detection system ensure it remains effective and in line with industry best practices. 11. Collaboration and Expertise: Complex grouting projects in high-pressure rock masses may require collaboration with geotechnical engineers, hydraulic experts, and experienced grouting contractors. Their expertise helps design and implement effective hydraulic jacking inspection systems and provides valuable insights into grouting processes, rock mass behavior and risk mitigation strategies. The safety and effectiveness of the grouting process can be enhanced by implementing a robust hydraulic jacking detection system and following good practice. Early detection of hydraulic jacking allows for timely intervention, preventing potential damage to the rock mass and ensuring the success of the grouting operation.
