  • Publication number: 20250101704
    Abstract: An underground space frame structure includes vertical support piles and multi-layer horizontal components. Each of the vertical support piles includes a pile body vertically disposed in a pile hole before excavating a foundation pit. The pile body includes an upper pile body and a lower pile body. The upper pile body is a rectangular body, and the lower pile body is a cylindrical body. An expansion section is located between the upper pile body and the lower pile body. A cross-sectional area of the expansion section is greater than a cross-sectional area of the upper pile body and a cross-sectional area of the lower pile body. The upper pile body, the expansion section, and the lower pile body are coaxially arranged from top to bottom in the pile hole. The multi-layer horizontal components are constructed from top to bottom.

  • Publication number: 20250101700
    Abstract: A drilling device for a reinforced concrete bored pile includes drilling masts, a scalable drill rod, a rotary drill bit, a rectangular cutter and scalable cutter rods. A top end of the scalable drill rod is connected to the drilling masts, the rotary drill bit is disposed on a bottom end of the scalable drill rod, the rectangular cutter is disposed above the rotary drill bit and defines a first drill rod hole, the scalable drill rod is disposed to pass therethrough. Bottom ends of the scalable cutter rods are connected to the rectangular cutter, and top ends of the scalable cutter rods are connected to a horizontal constraint platform, on which an impact component is provided. The horizontal constraint platform is disposed below the top end of the scalable drill rod, and the scalable drill rod passes through the horizontal constraint platform and the impact component.

  • Patent number: 11757669
    Abstract: Generating an agenda for a meeting includes creating a content repository that includes content corresponding to feedback from previous targeted meetings and/or information corresponding to ongoing discussions between potential attendees of the meeting, automatically creating a prioritized list of discussion topics, and at least one expert providing gestures to a computer screen to create an assessment for the discussion topics, display additional data for the prioritized list of the discussion topics, and/or transfer one or more of the discussion topics of the prioritized list of the discussion topics to either a list of dropped discussion topics or to an ordered list of selected discussion topics. An agenda is automatically generated based on the ordered list of selected discussion topics and on weights assigned to the at least one expert according to relative expertise. An order of agenda items is based in part on the weights.

  • Patent number: 11635527
    Abstract: It is provided a joint receiver and receiving method for navigation signals located at adjacent frequencies. The joint receiving method includes: receiving a first navigation signal and a second navigation signal which are located at adjacent frequencies (S1); and calculating a frequency estimation of a virtual wideband navigation signal constructed based on the first navigation signal and the second navigation signal (S2), wherein the virtual wideband navigation signal is an asymmetric BOC-like navigation signal having a virtual carrier and a virtual sub-carrier. With the joint receiver and joint receiving method, not only power gain but also bandwidth gain can be obtained, and the ranging precision can be significantly improved.

  • Patent number: 11204296
    Abstract: The present invention provides a horizontal instrument, a supporting device and a method for adjusting the bearing surface of the supporting device to be horizontal. The horizontal instrument in the present invention is used for maintaining a bearing surface parallel to a horizontal plane, wherein the horizontal instrument comprises a slide-swing assembly, and a monitoring assembly, when the monitoring assembly detects that the bearing surface is not parallel to the horizontal plane, the controller instructs the driving unit to drive the slider to slide, which leads the lower end of the swinging rod to slide, and then drives the swinging rod to swing, thereby, the upper end of the swinging rod drives the bearing surface to rotate for an angle so that the bearing surface is maintained parallel to the horizontal plane.
