The utility model provides a highway tamping device for highway engineering, which relates to the technical field of highway engineering and comprises a main plate, a support is fixed at the top end of the main plate, a hydraulic push rod is mounted at the bottom end of the support, a first pressing plate is fixed at the output end of the hydraulic push rod, and two ends of the first pressing plate are rotatably connected with rotating shafts. A connecting block is fixed to the outer wall of the rotating shaft, and a second pressing plate matched with the first pressing plate is fixed to the end, away from the rotating shaft, of the connecting block. During tamping, a user rotates two rotating shafts to drive two second pressing plates connected with two connecting blocks to rotate, so that the two second pressing plates can expand the pressing area of a first pressing plate, and the effect of improving overall tamping is achieved; water in the water storage tank can enter the communicating pipe and the water outlet pipe through the water inlet pipe and then is atomized and sprayed out through the atomizing nozzles, and water mist dust falling treatment can be conducted on dust generated by tamping.

The utility model relates to pit paper production technical field, concretely for a kind of for pit paper's gluing and mounting device. Including frame, glue tank, first drive belt, second drive belt, first power mechanism, guide roller and two limit rollers;First drive belt is installed on frame;Second drive belt is installed on the upper end of frame;First power mechanism is installed on frame for driving first drive belt and second drive belt synchronous movement;Guide roller and two limit rollers are rotatably installed at the bottom end of frame;Glue tank is located below guide roller, glue tank is rotatably installed with rubber-coated roller, glue tank is installed with the second power mechanism for driving rubber-coated roller rotation. The technical scheme can reduce the waste of glue in use, and the first drive belt and the second drive belt are used to press the pit paper, and the adhesion effect of pit paper is improved.
