The invention discloses a novel method for preventing and treating water burst of a deeply-buried reverse-slope tunnel. The novel method comprises the following steps that firstly, advanced waterproof grouting is conducted on a water-rich area of the deeply-buried reverse-slope tunnel; 2, digging and building construction is conducted on an excavation face, and if water burst suddenly occurs in the excavation process of the deeply-buried reverse slope tunnel, the step 3 is conducted; thirdly, the gushing water in the second step is guided into a water collecting pool in the tunnel; 4, in a non-water-rich area outside the tunnel and outside the influence range of the water area of the tunnel, a position is selected as a drainage injection and drainage area, the drainage injection and drainage area comprises a flat ground settling pond and a water injection area which are connected, the flat ground settling pond and a water collecting pond, and gushing water in the water collecting pond is treated and received; and the treated gushing water is injected into the water injection area. According to the method, the problem of gushing water discharge is solved through advanced water prevention, treatment in case of gushing water and injection of gushing water into stratum surrounding rock fractures.

The present application relates to the field of subway construction technology, and discloses a gas cushion balanced slurry shield slurry tank sediment and pipeline lagging discharge treatment method, which comprises the following steps: investigating and analyzing the determined lagging discharge pipeline, which is the pipeline between the first preset ball valve on the main slurry discharge pipeline and the slurry tank slurry discharge pipeline; setting a slurry circulation system and performing first cleaning on the lagging discharge pipeline; when the first preset ball valve does not meet the preset cleaning condition, the first preset ball valve is closed, and second cleaning is performed on the first preset ball valve based on the preset cleaning scheme; third cleaning is performed on the lagging discharge pipeline based on a layered reverse flushing mode until the preset cleaning requirement is met, and it is determined whether the lagging discharge pipeline cleaning is completed; long-time shutdown special measures of the slurry shield and special measures for excavation face stability during long-time shutdown of the slurry shield are determined, the present application can clean the lagging discharge soil of the main slurry discharge pipeline, solve the lagging discharge problem of the main slurry discharge pipeline, restore the normal tunneling of the shield machine, and ensure the construction safety.

The present application belongs to the technical field of two-phase discharge load analysis, and particularly relates to a two-phase discharge load numerical analysis system in a rapid transient process. In the present application, an analysis object recognition module is used to obtain the discharge system design characteristics of different components, and the obtained characteristics are transmitted to a numerical analysis module through a data transmission module for modeling and calculation. The key parameter information obtained by the numerical analysis module is transmitted to a key mathematical analysis module through the data transmission module. The key mathematical analysis module adopts different numerical analysis methods for different pipelines according to the discharge system design characteristics obtained by the analysis object recognition module. The key mathematical analysis module obtains real-time change data information of the load on each pipeline of the discharge system. The present application standardizes, unifies and simplifies the analysis process from obtaining the thermal hydraulic parameter change to finally obtaining the impact load in the complex two-phase discharge problem, and provides corresponding analysis tools for the mechanical analysis and design optimization of the discharge process.
