Abstract

In view of the existing trenchless technology, which cannot realize the pipe dragging construction of reinforced concrete round culverts, a round culvert with tensile performance and mechanical connection function is proposed. And the infiltration test and exfiltration test are carried out for the existing round culvert interface and sealing mode to determine the interface and sealing form that is most suitable for the new round culvert. The results show that the leakage situation of the sealing form using only the gasket is relatively serious, and the leakage rates of the sealant and the sealant + gasket are relatively small; the average exfiltration and infiltration rates of the all-encompassing sealant connection are the smallest and are more suitable for the new round culvert; and the leakage coefficients in the Darcy model and the Torricelli model under various situations of different interfaces and sealing methods are obtained through experiments.
