Abstract:
The concrete for the lining of the passengerdedicated railway tunnels are produced as per the requirements for durable concrete. The raw material quality, workability and transportation and casting technologies of the concrete have their own special requirements. Due to the problems in the construction organization, concrete's workability, concrete construction equipment and working labors, pipe blocking may occur during the pumping of the concrete. On basis of the concrete construction of No. 3 bid section of Hefei～Wuhan passengerdedicated railway, the author summarizes the reasons for the pipe blocking and their prevention measures in the paper.
Key words: passengerdedicated railway tunnel pumped concrete pipe blocking reason, prevention measure
