The utility model relates to a road pipeline pitshaft driving system, this system include the suspension bridge subassembly and strut the mechanism, the suspension bridge subassembly includes temporary steel bridge and suspension bridge buttress, temporary steel bridge sets up on the suspension bridge buttress, temporary steel bridge's upper surface and road surface flush, it includes lock catch ring roof beam and shaft lateral wall to strut the mechanism, the lock catch ring roof beam sets up in the inboard of suspension bridge buttress, and the vertical height of lock catch ring roof beam isless than the vertical height of suspension bridge buttress, and the two is thrown out of gear each other. Realized can not influencing the road on the daytime that the flow of the people is big through the suspension bridge subassembly, in the little construction at night of flow of the people, reduced the influence to the traffic. Through strutting the mechanism, the safety of traffic has beenguaranteed.
