The invention relates to a macadam device and in particular relates to a macadam device for hydraulic engineering. The invention provides a macadam device for hydraulic engineering, which has the advantages of being capable of rapidly treating macadam, saving manual labor and being convenient to use. The macadam device for hydraulic engineering, provided by the invention, comprises a base, a firstsupporting rod, a second supporting rod, a first rotating shaft, a first bearing and the like, wherein the first supporting rod is arranged at the left upper part of the base; the second supporting rod is arranged at the right upper part of the base; a fourth supporting rod, a third supporting rod and a grinding frame are sequentially arranged at the right part of the first supporting rod from top to bottom; and a second bearing is arranged at the left part of the grinding frame. According to the device disclosed by the invention, the effects of being capable of rapidly treating the macadam,saving the manual labor and being convenient to use are achieved, and due to use of the equipment, lots of macadam can be rapidly ground, and the manual labor is saved. Moreover, the produced dust canbe absorbed with clean water on the device, any influence caused to operations of workers is avoided, and the construction speed of the hydraulic engineering can be increased.

The present invention provides a micro-nano structure closed pipeline and a preparation method thereof. The preparation method comprises: 1) providing a substrate, forming a flexible material layer on the substrate surface, and forming a plurality of concave groove structures on the flexible material layer surface; 2) forming metal layers on the surfaces of each flexible material layer and various concave groove structures; and 3) providing a metal thin film, achieving the surface and surface fusion welding of the metal film and the metal layer by using an ultrasonic welding process, and forming a plurality of closed pipelines. According to the present invention, the ultrasonic welding process is used, the surfaces of the two layers of the metals are subjected to mutual friction during the work process to form the intermolecular fusion so as to form the closed pipeline, the fusion position is at the molecular layer level, and the concave groove is not affected; the process is simplified, and the product has characteristics of heat resistance and compression resistance; and characteristics of no glue adhering, product thickness reducing, sealing property ensuring and service life prolonging are provided.

The invention discloses a buffered sliding mechanical limiting device, which belongs to the technical field of limitations to the motions of revolution bodies. The device comprises a movable limiting block, a left limiting combination and a right limiting combination, wherein the movable limiting block is wholly cambered, and is fixedly connected to the revolution part of revolution equipment; the left and right limiting combinations are identically structured and symmetrically arranged; each of the left and right limiting combinations comprises a limiting seat, a sliding block and pressure plates; a limiting damper is arranged in the limiting seat; the sliding block is provided with a cavity; four corners at the lower end of the sliding block are outwards extended to form a sliding rod respectively; the limiting seat is fixedly connected to the fixed part of the revolution equipment; the pressure plates and the limiting seat form four guide sliding rails; the sliding block is sleevedon the limiting seat; one side of the sliding block contacts the limiting damper; and each sliding rod on the sliding block is positioned in corresponding guide sliding rails. When the movable limiting block impacts the sliding block, the limiting damper absorbs the moment of inertia of the revolution equipment to weaken the rigid impact force of the revolution equipment and finally stop the revolution of the revolution equipment. The buffered sliding mechanical limiting device has the advantages of convenience of assembly and disassembly, long service life, impact resistance, high safety, high universality and the like.
