Rapid plugging method for fiberglass pipeline with water and pressure

Abstract

The invention relates to a rapid plugging method for a fiberglass pipeline with water and pressure. The method comprises the following steps of: manufacturing a rubber ring (4) for a damaged mouth (5) on the fiberglass pipeline (1); tightly adhering a semicircular fiberglass water sealing belt to the rubber ring (4) to form a mouth-repairing reinforced plate (6); respectively coating and clamping one tension tighten device (2) out of the fiberglass water sealing belt near two sides to seal an opening of the damaged mouth (5); artificially winding and pasting fiberglass alkali-free roving cloth and unsaturated polyester resin at a mouth-repairing area (7) at the right middle of the repaired mouth reinforced plate (6) of the fiberglass pipeline (1) until a mouth-repairing area is solidified and reaches a bearing capacity; respectively releasing the tension tighten devices (2) at both left and right ends at the damaged mouth (5); and respectively winding and pasting the fiberglass alkali-free roving cloth and the unsaturated polyester resin at the left and right end heads of the ready-made mouth-repairing area (7) in the middle until the new formed mouth-repairing area (7) which integrates the existing cure. On the premise of ensuring the normal operation of the damaged pipeline, the fiberglass pipeline is plugged rapidly and efficiently.

Description

technical field [0001] The invention relates to F16L pipes, pipe joints or pipe fittings, and maintenance methods and technologies, especially the technology of fast leakage plugging with water and pressure when the glass fiber reinforced plastic pipe encounters abnormal damage. Background technique [0002] In the known technology, FRP pipes have good heat resistance, frost resistance, wear resistance and pressure resistance, and have many advantages such as light weight, high strength, convenient transportation and installation, and low maintenance costs. They have been widely used in the field of engineering construction, but in the process of use In the construction of other underground projects and structures, the artificial or mechanical damage to the buried FRP pipes is often caused. The traditional leakage repair method generally adopts manual winding paste of glass fiber and polyester resin in the absence of water, pressure and other fluids after the fluid in the FR...

AI Technical Summary

Problems solved by technology

[0003] 1. The water cut-off time is long, the larger the pipe diameter, the longer the water cut-off time, about 1-3 days

[0004] 2. It is difficult to discharge the fluid in the pipeline, and some places have no place to discharge due to environmental and space restrictions. Even if it can be discharged, it will cause waste of fluid resources in the pipeline

[0005] 3. During the discharge process, the pipeline system is basically out of service, which brings a great deal of loss and inconvenience to production and life
