Abstract: Aiming at the phenomenon of pumping concrete used for bridge and culvert construction in expressway construction, which is prone to block pumping and difficult pumping during the pumping process, this article analyzes the reasons for it, expounds the actual solution during the construction process, and provides a follow-up Accumulate experience and lessons during construction. Avoid recurrence of similar problems during construction or difficulty in solving problems after they occur, which will delay the progress of the project.
