Technical Field

[0001] The utility model belongs to the technical field of urban rail transit construction, in particular to a device for simulating dynamic seepage in freezing method construction. Background Art

[0002] With the continuous advancement of urbanization, the development and utilization of urban underground space has become increasingly important. Major cities have accelerated the construction of underground commercial complexes, underground garages, subways, and other structures. Against this backdrop, the freezing method, with its advantages of high soil reinforcement, excellent water-stopping properties, and unrestricted construction sites under surface conditions, has gradually become one of the preferred methods for urban underground construction and has been widely adopted.

[0003] However, current freezing methods still have limitations. Existing technologies mostly simulate the freezing process statically, failing to effectively reflect the dynamic changes in groundwater in complex environments. This is particularly true in coastal areas, where groundwater velocity and direction vary significantly with the cyclical nature of the tides. This dynamic nature of the hydraulic environment is not fully accounted for in traditional freezing methods, making it difficult to accurately predict and control the results.

[0004] To solve this problem, it is urgent to develop a new device that can simulate the dynamic changes of groundwater seepage. This device should be able to flexibly adjust the seepage direction and flow rate to better reproduce the complex hydraulic conditions in actual projects. This dynamic seepage simulation device will provide more accurate technical support for freezing method construction and significantly improve the reliability and safety of construction.
