Emergency-repair tool for pipe line of prestress steel cylinder concrete pipe

Abstract

The invention discloses an emergency-repair tool for a pipe line of a prestress steel cylinder concrete pipe. The tool comprises a connecting piece, a bearing part and a seal part which are respectively arranged at two ends of the connecting piece, wherein the bearing part comprises two semi-circular bearing plates which can be split and combined; the circle area formed by splitting the two semi-circular bearing plates is greater than the area of a damaged opening on a pipeline; the seal part comprises a seal plate and a fastening piece, wherein the area of the seal plate is greater than the area of the damaged opening on the pipeline; and the semi-circular bearing plate and the seal plate can be movably and respectively arranged at two sides of the damaged opening on the pipeline. In the emergency-repair tool for the pipe line of the prestress steel cylinder concrete pipe, through arranging the bearing part and the seal part, the damaged opening at the inner part and the outer part of the pipe line is respectively sealed, then further concrete is filled in the seal space, and the repair of the pipe line of the prestress steel cylinder concrete pipe can be realized, thus the emergency repair work of the pipe line can be finished without draining water in the pipe line completely.

Description

technical field [0001] The invention relates to a repair tool, in particular to a repair tool for prestressed steel cylinder concrete pipelines. Background technique [0002] After the prestressed steel cylinder concrete pipeline is buried, sometimes it will be accidentally driven by piling machinery because the bottom line pipeline is unclear, resulting in pipeline leakage. [0003] The traditional emergency repair method is to smash the prestressed steel cylinder concrete pipe and pipeline thoroughly, clean them out, and then lay the prestressed steel cylinder concrete pipeline and pipeline again. Such an emergency repair mode needs to empty the water in the original pipeline before operation can be carried out. Assuming that the length of the damaged pipeline is 10 kilometers and the diameter of the pipe is 2 meters, more than 30,000 tons of water need to be drained before it can be repaired. This kind of emergency repair method not only wastes a lot, but also takes a l...
