Novel civil engineering damping device

The utility model relates to the technical field of civil engineering, and discloses a novel civil engineering damping device which comprises a base, the inner wall of the base is slidably connected with a square plate, the top of the square plate is fixedly provided with a first fixing block, and the inner wall of the first fixing block is rotatably connected with a telescopic rod. The end, away from the first fixing block, of the telescopic rod is rotationally connected with a second fixing block, and a cylinder is fixedly mounted on the outer wall of the second fixing block. According to the novel civil engineering damping device, when a pressure plate is pressed through a cylinder to move up and down, the cylinder drives a telescopic rod to drive a square plate to expand towards the two sides through a first fixing block, so that the square plate assists in supporting, and meanwhile, the contact area between equipment and the ground is increased, and the inner wall of a notch is matched with the outer wal
