Different-sized holes can be punched in the road bridge through the punching mechanism 6, making it suitable for the construction of various different road bridges. By starting the first motor 5 and the second motor 64, the punching heads 65 can be rotated and moved downward to the punching position, and at the same time, the use of different punching sizes can be ensured, thereby improving the applicability of the device. On both sides of the inner walls of the upper two punching heads 65, sliders 66 are fixedly arranged. On both sides of the outer walls of the lower two punching heads 65, chutes 67 are opened.
