  • Patent number: 12084973
    Abstract: Disclosed is a blockage-proof water diversion and drainage device for highway tunnel construction. The device may include an inlet cleaning component, a diversion component connected to a bottom of the inlet cleaning component, a debris collection component connected to an end of the diversion component close to the inlet cleaning component, and a pre-storage component connected to a bottom of the diversion component. An outlet end of the pre-storage component may be connected to the debris collection component. An openable baffle component and a screen plate may be provided inside a main pipe of the diversion component which can transfer filtered sludge and other debris to the debris collection component, keeping the main pipe clean, maintaining the drainage speed of accumulated water, and reducing the frequency of manual cleaning. Additionally, the device can scrape and clean a surface of the screen plate to prevent blocked, thus extending device maintenance time.

  • Patent number: 12065797
    Abstract: The present disclosure provides a rod-type pile foundation for preventing a pile body from being heaved and an operating method. The rod-type pile foundation comprises a base, a support block fixed inside the base, a support plate movably disposed at a top of the support block by a guide structure, and an anti-frost heaving component located at a lower portion of the support block. The anti-frost heaving component includes a first connecting rod rotationally connected with the support block and one or more telescopic rods. One end of each of the telescopic rods is fixed on the first connecting rod. A scraping plate is fixed at another end of each of the telescopic rods. The support plate is in transmission connection with the first connecting rod through a transmission component. The transmission component converts a vertical linear motion of the support plate into a rotation of the first connecting rod.

  • Patent number: 12055533
    Abstract: A monitoring device for methane gas in a hot thaw lake pond in a tundra region is provided, comprising a top plate, an adjusting mechanism, and a monitoring mechanism. A bottom portion of the top plate is fixedly connected with a fixed column, and the fixed column is slidably mounted on the adjusting mechanism. The monitoring mechanism is connected to the adjusting mechanism, and the monitoring mechanism controls entry and exit of water to be detected and detect a methane gas in the water. The position of the mounting cylinder of the monitoring mechanism is adjusted by an electric push rod to facilitate the monitoring of methane concentration at different positions.

  • Patent number: 11892101
    Abstract: Embodiments provide anti-frost heaving supports and methods for crude oil pipeline crossing permafrost region. The anti-frost heaving support includes a support frame. An arc-shaped frame is installed on a top of the support frame. Two sets of adjusting devices are disposed on the arc-shaped frame, each set of the adjusting devices includes a pushing device fixedly installed on the arc-shaped frame. In the anti-frost heaving support, a piston plate compresses air inside the sealing frame so that a compressional force of an elastic plate and a stressed plate on the pipeline increases. When the compressional force increases, the elastic plate deforms to make a moving rod to move towards to an interior of the sealing frame. When moving on a tilted surface of a tilting plate, the moving rod pushes the tilting plate to move. The tilting plate pushes the sealing plate to be opened to release the air inside the sealing frame, thereby reducing the compressive force exerted by the stressed plate on the pipeline.
