Abstract: The invention belongs to ecological revetments in the technical field of river ecology, which particularly involves an ecological revetment to regulate wandering rivers. The ecological revetment is composed of porous concrete-piles, ecological connecting-plates, an ecological viewing-corridor and a slope green-belt.

Abstract: An integrated system comprising a barrier, such as a weir with movable gates, controllably blocks water flow in a natural or concrete lined channel. Without substantially impeding flow in normal conditions, the barrier is configured to back up flood waters to spill into an upstream prepared detention basin. Water is thus kept from downstream areas until subsequently drained through a controlled spill. Multiple units installed in a watershed can store significant amounts of flood water, e.g., during a hurricane, protecting life and property downstream. The electromechanically-operated gates can be operated locally or from a remote control center. Gauges and sensors positioned near the weir and/or throughout the watershed can provide data used to control one or more barriers in the watershed, and the data may be used to train a machine learning model to control the system.

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.
