  • Publication number: 20250103765
    Abstract: The present disclosure provides a method for predicting a three-dimensional frost heaving deformation of a formation during freezing construction of a metro tunnel and relates to the field of metro tunnel construction. The method includes: firstly determining a freezing construction position, obtaining soil horizon parameters of undisturbed soil within a range of a freezing wall, determining thermophysical and mechanical parameters of soil, layering a soil horizon above the freezing wall according to soil horizon properties thereof and existing buildings (structures), and determining a horizon where a frost heaving influence range exists; subsequently calculating an unsteady temperature field of a single freezing pipe and a radius of a freezing front; then calculating an inner radius and an outer radius of the freezing front after closure of the freezing wall according to a tunnel excavation type, and calculating a frost heaving region; and finally calculating a frost heaving displacement.

  • Patent number: 11882871
    Abstract: A detachable atomizing device and a container thereof are provided. The container is detachably assembled to an atomizing assembly. The container includes a cup and a flexible film. The cup has an opening arranged at an end thereof, the flexible film covers the opening of the cup, and the flexible film has a tension region and an outer ring-shaped region that surrounds the tension region. The tension region has a plurality of atomizing holes having an average diameter within a range of 1 ?m to 20 ?m, and the outer ring-shaped region is attached to the cup. When the cup is assembled to the atomizing assembly, a tension value of the tension region of the flexible film is increased from an initial tension value to an atomizing tension value by being pressed from the atomizing assembly, and the atomizing holes of the tension region are configured to allow liquid to pass there-through and to be formed as aerosol mist having an average atomized particle diameter less than a predetermined value.

  • Publication number: 20070262958
    Abstract: The present invention relates to a finger-worn input device, which comprises a movement detecting unit, a main controller and a connection structure. After being assembled, users can insert their finger in between the movement detecting unit and the main controller in order to move the movement detecting unit and to press a key. The main controller receives a movement signal and a key signal, converts these signals into a computer control signal, which is then transmitted to a computer for further process through a wired or wireless transmission method. By using the finger-worn input device with the structure mentioned above, the user usage is more convenient and the input device can be minimized. In addition, the present invention also discloses an input method applying the finger-worn input device.
