When the push plate 16 moves, it will push the extension plate 14 upward to adjust the support height of the roadbed construction, so as to prevent the paving material from exceeding the support height of the device due to the high paving material during the support process, thereby affecting the construction of the roadbed. When the push plate 16 slides to one side under the pressure of the swing plate 9, one end of the push plate 16 will push the extrusion plate 30 to move to one side. At this time, the extrusion plate 30 will squeeze the airbag 32 when moving, and the gas inside the airbag 32 will be transported to the inside of the drawing groove 33 through the conduit 34 after being squeezed. The air pressure inside the drawing groove 33 will increase with the input of the gas. At this time, the reinforcement plate 37 will move downward under the action of the air pressure, so that the tooth block 38 contacts the ground, thereby increasing the grip of the reinforcement plate 37 through the tooth block 38, thereby improving the stability of the device for supporting the roadbed construction, preventing the device from being subjected to a large pressure due to the laying of construction materials during the support process, thereby causing the position of the device to tilt, and then causing the roadbed to tilt during construction, affecting the construction of the roadbed.
