Description
Technical field
The invention patent belongs to the method that the buried pipeline leakage in underground of industrial cycle water installations carries out repairing with pressure, more
Specifically, it is related to a kind of buried underground piping emergency repair method with pressure, and it is different straight that this method is suitable for water class underground, ground
Diameter, wall thickness 8mm or more, the defect elimination with pressure work that design pressure 0.6MPa pipeline below is revealed by defect.
Background technique
In the commercial plants such as chemical industry, chemical fertilizer, petroleum the industrial waters such as recirculated water, fire water, desalted water, life water be can not
Lack, water is transmitted by pipeline, and pipeline uses for a long time, is opened because the reasons such as burn into washes away, external force will cause pipeline
The defects of splitting, perforating reveals water from fault location, can be to rob by cracking block of leak source in the case where not parking
The technical problem repaired, it is especially buried more difficult by force in underground piping, it generallys use and stops in pipe first-aid leak source
Vehicle replaces the methods of leak source repair welding, fast hardening concrete pouring, but influences production using parking leak source repair welding, and Large Scale Industrial Process is every
Parking drives once lose members up to a million, feasible for small defect using fast hardening concrete pouring, if big perforation is adopted
It is poured with fast hardening concrete, is easy to pour into concrete inside pipeline, causes the equipment, valve blockage or damage in downstream.It adopts
The deficiency of the above method can effectively be made up by carrying out repairing pipeline leakage point with a kind of buried underground piping emergency repair method with pressure.
Summary of the invention
The purpose of present invention is the shortcomings that overcoming existing method for maintaining, and provides that a kind of buried underground piping is with pressure to be robbed
The method repaired.
In order to complete present invention purpose, the application uses following technical scheme:
The method of buried underground piping repairing with pressure of the invention, this method be to by the buried pipeline in underground of soil layer into
