Abstract： Inorder toachieve efcient lane retention，taking the 311O9 transportation channelas theresearch object， theflexible formwork concretefiling laneretention technology isapplied to the transportationchannellane retention and engineering practiceiscarriedout.Basedontheon-site situationof the 31109 transportation channel，the technical solution is provided forretaining lanes，andthe engineering application efect isanalyzed.Afteron-site application， thefiling material strength of the31109 transportationchannelreservedroadwaysection isrelativelyhigh，and the maximum deformationof theroadwayroof andfloor，aswell as the twosides，are 587mmand495mmrespectivelyand the engineering application effect is good.
