Abstract

The utility model relates to a double sealed water stop interface for steel bell end reinforced concrete pipelines. The interface is mainly installed in a socket and a bell end at the end portions of two adjacent pipes. A bell end steel lantern ring with a guide slope is buried at the bell end, and a socket steel ring with two annular grooves formed by two thrust collars is buried at the socket. Annular sealing rings are inlayed inside the two annular grooves, and the middle of the two annular grooves is provided with a pressure testing hole. The double sealed water stop interface resolves the technical problem of the sealing-up failure of annular sealing rings and pipeline leakage caused by the uneven pressure-bearing of the annular sealing rings in the steel bell end reinforced concrete pipelines and even a land subsidence caused by the sand outside the pipelines flooding into the pipelines in the prior art.
