More Information
Summary:The method comprises the steps that a freezing pipe is put into a to-be-treated strip mine test area, a refrigerant is put into the freezing pipe to obtain freezing parameters of the freezing pipe, and the refrigerant is stopped from being put into the freezing pipe to obtain ice melting parameters; obtaining size data of a to-be-treated strip mine, and determining the placement position of a freezing pipe in combination with the freezing parameters of the freezing pipe, the ice melting parameters, the construction progress and the target frozen soil wall strength; and the freezing pipe is placed according to the freezing pipe placing position, the same refrigerant is put for freezing, and strip mine landslide treatment is achieved. Freezing bodies are formed on the sliding surfaces, so that the anti-sliding resistance is increased, and the slope is prevented from sliding. The method is suitable for various soil layers, and is especially suitable for projects with large water content and weak strata. 本发明公开了一种
