摘要： Provided are a device for simulating a full-scale pile-sinking process of a static pressure pile by air bag preloading and a test method thereof. The device comprises a frame, a beam, a hydraulic jack, a model box, a model pile, a first sand layer, an undisturbed soil mass, a second sand layer, a rubber pad, a forcing air bag, a counter-force steel plate, a model box top cover, a forcing pipe, a pressure relief pipe, a steel casing and a control system. The first sand layer, the undisturbed soil mass, the second sand layer, the rubber pad, the forcing air bag and the counter-force steel plate are laid in the model box in sequence; and the steel casing passes through the model box top cover, the counter-force steel plate, the forcing air bag and the rubber pad in sequence and then reaches a bottom portion of the second sand layer.

摘要： A concrete inside interface processing structure for secant pile construction, including secant concrete pile, formed plain concrete pile, rotary jet grouting piles, steel mesh sheet, ribbed steel bar, Y-shaped connecting piece, reinforced concrete pile, and U-shaped connecting piece; drilled holes are arranged at intervals along axis of the formed plain concrete pile; the ribbed steel bar is anchored in each drilled hole; the steel mesh sheet is formed by connecting longitudinal bars and transverse bars, and driven into a soil body between the formed plain concrete piles; the concrete layer is formed by spraying concrete on the steel mesh sheet; the reinforced concrete pile is cast at outside of the formed plain concrete pile, and tangent to the formed plain concrete pile, and interlocked with the rotary jet grouting piles; the rotary jet grouting piles are tangent to the formed plain concrete pile or secant concrete pile.
