The application belongs to the technical field of soil improvement and remediation, and particularly relates to a spray-explosion type deep loosening and deep application integrated engineering equipment and a working method thereof. The equipment comprises a vehicle frame, a spray-explosion system, a spray-explosion deep loosening rod and a feeding system. The vehicle frame is provided with traveling wheels. The spray-explosion deep loosening rod is internally provided with a spray-explosion channel. The lower end of the spray-explosion deep loosening rod is provided with at least one spray-explosion hole, which is not directed downward. The upper end of the spray-explosion channel is communicated with the gas outlet of the spray-explosion system through a pipeline. The lower end of the spray-explosion channel is communicated with the spray-explosion hole. The spray-explosion system is used for generating a compressed air shock wave and forming spray-explosion through the spray-explosion deep loosening rod. The feeding system comprises a feeding tank and a discharge pipe. The upper end of the discharge pipe is communicated with the outlet of the feeding tank. The lower end of the discharge pipe is communicated with the spray-explosion deep loosening rod. The spray-explosion loosening and spray-mixed fertilization are simultaneously performed. The fertilizer is sprayed into the loosened soil through the spray-explosion mode. The fertilizer is sprayed through the positive pressure gas, so that the fertilization area is larger.

This invention relates to the field of intelligent teaching technology and provides an integrated engineering-learning intelligent teaching system for intelligent operation and maintenance of rail transit. In this system, a teaching data platform module aggregates and processes teaching data; a teaching twin module constructs a three-layer twin model and generates multi-dimensional teaching tasks; an integrated engineering-learning teaching engine module automatically arranges the optimal sequence of teaching activities based on student competency profiles and teaching tasks through reinforcement learning; a metaverse scene construction module constructs immersive simulation training scenarios based on this sequence; a competency evolution assessment module analyzes student training data and generates a competency increment map; and a teaching feedback optimization module feeds this map back to the task generator to drive a new round of teaching. This invention achieves dynamic generation, intelligent arrangement, precise assessment, and closed-loop optimization of teaching in the field of intelligent operation and maintenance of rail transit, solving problems such as insufficient intelligence, mismatched teaching strategies, mismatch between engineering and learning, and a single method of evaluating teaching quality in rail transit teaching.

This invention relates to the field of intelligent water conservancy engineering technology, specifically to a water conservancy emergency resilience control method and system based on digital twins and knowledge graphs. It includes a spatiotemporal knowledge graph based on integrated engineering entities, historical cases, and expert rules; real-time matching of disaster scenarios using graph computing to generate preliminary emergency strategies and risk predictions; extraction of features from the preliminary strategies using few-sample learning; and fine-tuning and hardening of the strategies using an optimizer embedded with physical information constraints to obtain physically reliable refined control plans. Multiple refined plans are simulated and deduced in parallel within a digital twin; based on the deduction results, the optimal emergency control instruction set is selected and output with the goal of maximizing system resilience, while simultaneously updating the spatiotemporal knowledge graph. This invention, through a three-level intelligent pipeline, achieves second-level experience reuse, scientific customization and adaptation, and global optimization through simulation in emergency decision-making, significantly improving the emergency response speed, scheme reliability, and overall resilience of water conservancy systems.
