The outer wall of the mounting seatis in sliding connection with a mounting sleeve and is further provided with a check ring used for abutting against the lower end of the mounting sleeve. Multiple grooves are vertically formed in theinner wall of the mounting sleeve. A transmission rack is embedded in each groove. Multiple mounting grooves communicating with the grooves are formed in the outer wall of the mounting seat. Gears engaged with the transmission racks are rotationally connected in the mounting grooves. The pier base further comprises a supporting seat and a top seat. Multiple supporting rods are vertically arrangedon the lower end face of the supporting seat. Mounting holes allowing inserted connection of the supporting rods are formed in the upper end face of the mounting seat. The mounting grooves communicatewith the middles of the mounting holes. Active racks engaged with the gears are arranged on the outer side walls of the supporting rods. The wooden municipal bridge pier base has the following advantages that the joint pier base is arranged to replace a traditional integrated pier base, the mounting process of the pier base is more convenient and faster, and then the effect of facilitating mounting and use is achieved.
