The utility model provides a high-water-level sandy soil deep foundation pit supporting device. The high-water-level sandy soil deep foundation pit supporting device comprises fender piles. The positioning structure is clamped to the top end of the fender pile, the positioning structure comprises a positioning plate, a positioning groove and a positioning hole, the positioning groove is formed in the bottom face of one end of the positioning plate, and the positioning hole is formed in the side wall of the other end of the positioning plate; the fixing structure is fixed on the edge of the bottom surface in the foundation pit; the protection structure is mounted between the positioning plate and the fixing groove; the high-water-level sandy soil deep foundation pit supporting device has the advantages that the construction time is conveniently shortened, and the cost input is reduced.

The invention discloses an intelligent paver one-button control method and system based on parameter multiplexing, and belongs to the technical field of paver equipment. According to the method, a central controller is controlled to automatically execute a preset transition or construction operation action sequence through a one-key operation instruction, and the action sequence comprises the actions of closing / opening a hopper, lifting / descending an ironing plate, stretching / retracting a hopper telescopic pin and a large arm pin, lifting / descending a material distribution frame, switching gears and the like. In the construction process, the system collects and stores construction parameters in real time through a sensor, and two modes of active recording and passive recording are supported. And when the construction mode is entered again, each execution mechanism can be automatically recovered to the recording state according to the historical parameter file, so that the consistent multiplexing of the construction parameters is realized. The method further has the functions of fault real-time detection, voice prompt and closed-loop adjustment, the operation difficulty is effectively reduced, and the automation degree of paving operation and the construction quality stability are improved.
