A perforation apparatus for a through-hole permeable pavement

Abstract

This invention discloses a perforating device for a through-hole permeable pavement, relating to the technical field of drilling devices. It includes a base frame with C-shaped columns fixedly installed on both upper sides of the base frame. A connecting plate is positioned between the C-shaped columns, and slidingly mounted on the inner walls facing each other of the C-shaped columns are connecting square plates. A top plate is fixedly installed between the connecting square plates, and an elevating screw is installed through the top end of the connecting square plates via threads. This invention enables multiple drill bits to operate simultaneously, thereby increasing the quantity and efficiency of drilling.
