ActiveCN105804100AReduce frictionImprove the lubrication effectProtective foundationExcavationsLandslideEngineering
The invention discloses an inclined arrangement mini pile structure. The inclined arrangement mini pile structure is used for fixing a landslide mass on a base rock. The inclined arrangement mini pile structure comprises at least one group of mini pile assembly which penetrates through the landslide mass to be fixedly connected with the base rock. Each group of mini pile assembly comprises at least three mini piles and a top plate which is arranged on the surface of the landslide mass and used for connecting the mini piles into a whole. The mini piles include the first mini piles, the second mini piles and the third mini piles. The second mini piles are perpendicular to the surface of the landslide mass. The first mini piles are arranged in an inclined mode in a direction facing the exerting direction of thrust of the landslide mass. The third mini piles are arranged in an inclined mode in the exerting direction of the thrust of the landslide mass. Lubricating interlayers are disposed between parts, located in the landslide mass, of the first mini piles and the landslide mass. By means of the inclined arrangement mini pile structure, the effect that the inclined piles towards the thrust of the landslide mass always have pre-tightening force can be ensured, and the whole mini pile structure is better in slope fixing effect.

Thermal force compression sealing device
The invention discloses a thermal force compression sealing device in the technical field of shaft end sealing structures. The device comprises a sealing seat arranged on a conditioning device shell and a rotating shaft movably arranged at the center of the sealing seat in a sleeving mode, a sealing filler is pressed between the outer wall of the rotating shaft and the inner wall of the sealing seat, the outer side end of the sealing seat is provided with a gland for pressing the outer side face of the sealing filler, the inner side end of the sealing seat extends into the conditioning deviceshell and is provided with a sealing groove, a groove opening of the sealing groove is provided with a movable gland for compressing the inner side face of the sealing filler, the movable gland is circumferentially positioned on the sealing seat and can move axially along the sealing seat, and an internal hollow sealing cavity structure is formed between the movable gland and the sealing groove. The thermal force compression sealing device has the advantages that it is ensured that the rotating shaft are tightly pressed through the inner side and the outer side of the sealing filler at the same time, and therefore, the device is suitable for sealing of the rotating shaft end of a feed conditioning device, and the sealing effect is improved.
