Technical Field

The invention relates to the technical field of agricultural pipeline leakage stoppage, in particular to a rapid leakage repairing method for a special pipe for water-saving irrigation of a farmland.

Background

The special pipe for water-saving irrigation of farmland has excellent quality, low price and great market demand, but under the severe environment of farmland cultivation, the damage to the conveying pipeline cannot be avoided, the time consumed by leak repairing and the increased material cost of the traditional method are not acceptable, and a quick and low-cost leak repairing method is urgently needed to replace the traditional method.

Disclosure of Invention

Technical problem to be solved

Aiming at the defects of the prior art, the invention provides a rapid leak repairing method and structure for a special pipe for water-saving irrigation of a farmland, and solves the problems of high cost and poor timeliness.
