This utility model relates to the field of concentrate powder sampling technology, specifically to a ton-bag concentrate powder sampling device for use during the freezing period in extremely cold regions. One end of the sampling probe is provided with an incised perforated tooth pattern, and the other end is provided with an annular limiting buckle. The sampling probe has a strip-shaped pressure relief groove area, which is arranged along the axial direction of the sampling probe. Two anti-freeze hydraulic cylinders are arranged in parallel. The piston rod ends of the two anti-freeze hydraulic cylinders are connected to the push plate, and the bases of the two anti-freeze hydraulic cylinders are mounted on the fixed base plate. A movable sampling frame is provided between the two anti-freeze hydraulic cylinders, one end of which is connected to the push plate. The movable sampling frame has multiple pull-out slots that match the annular limiting buckle. Both the push plate and the fixed base plate have grooves that allow the sampling probe to pass through. This utility model enables efficient, accurate, and reliable sampling of ton-bag concentrate powder in extremely cold regions.

This utility model relates to the field of thermal insulation wall technology, specifically disclosing a connection structure for thermal insulation walls, including a sleeve. A first protective plate is provided at the right end of the sleeve, and a second protective plate is fixedly connected to the left side of the sleeve. A threaded rod is slidably connected inside the sleeve, with a tapered head threaded to one end of the threaded rod. An expansion sleeve is slidably connected to the outer wall of the threaded rod. By setting multiple levels of expansion sleeves, appropriate sleeves can be flexibly selected for expansion anchoring according to different foundation wall environments. When facing dense walls, a suitable sleeve can be selected to achieve a stable connection; when encountering loose walls, a higher-level sleeve can be used to enhance the interlocking effect. This structure enables the connection structure to maintain reliable anchoring in various wall environments, effectively improving the adaptability and stability of the thermal insulation wall connection, expanding the application range of the connection structure, and meeting diverse installation needs.

The application provides an anchoring type pile foundation beam gravity retaining dam structure, relates to the geological disaster prevention engineering technical field, and is suitable for debris flow prevention engineering under high and steep slope or soft foundation conditions. The structure comprises a dam body, a beam, an anti-slide pile, a continuous beam and a prestressed anchor cable system. The dam body is a cast-in-place structure and is arranged on the beam, the beam is connected with the anti-slide pile, the top of the anti-slide pile is transversely connected through the continuous beam to form an integral force structure, anchor holes are pre-set in the beam, the prestressed anchor cable system is arranged in the anchor holes and is connected with the foundation to make the dam body, the beam, the anti-slide pile and the foundation bear force cooperatively. The structure can reduce the excavation amount, improve the overall stability, the anti-slide capacity and the anti-overturning capacity of the retaining dam, and enhance the structural rigidity, and is suitable for complex geological conditions such as rock, soil and composite stratum.
