Road is put in former circulating water pipeline；
C) cement injection mortar between the described GRP pipe being lining into and described former circulating water pipeline, the institute that will be lining into
State GRP pipe bonding with described former circulating water pipeline become an entirety.
As one kind improvement to technical scheme of the present invention, the described GRP pipe being lining into is in described former recirculated water
Assembled using orbital method inside pipeline.
As one kind improvement to technical scheme of the present invention, the described GRP pipe being lining into is using double " o " type circles
Socket joint connects.
As one kind improvement to technical scheme of the present invention, the water pressure test is at two of described double " o " type circle socket joints
Carry out between " o " type circle.
As one kind improvement to technical scheme of the present invention, the direction of the inside water pressure water filling port of the described water pressure test
Inwardly, shown inside water pressure water filling port is located at described in two between " o " type circle.
Therefore, the circulating water pipeline being lined with glass reinforced plastic pipe that the present invention provides, both served to former pipe of concrete or steel pipe
The effect of reinforcing, can effectively prevent the GRP pipe play being lining into again, improve the critical external compressive resistance ability of pipeline, Neng Gouchong
The feature that former pipe of concrete or steel pipe remaining critical external compressive resistance advantage are waved in distribution and the GRP pipe internal pressure-resistant that is lining into is good, due to lining
The glass reinforced plastic pipe entering is solely subjected to internal pressure, and the cost of bushing pipe can be greatly lowered, the circulation being lined with glass reinforced plastic pipe that the present invention provides
Waterpipe be lining into fiberglass tube method, excavate or side local half is excavated, earth excavation, backfilling working amount using top local is shallow
Little, short construction period, expense is few；Squeeze into steel-pipe pile and steel plate between pipeline, can effectively prevent from normally running the soil around pipeline
Earth comes down, collapses；Using orbital method assembling, can effectively ensure pipeline concentricity, connect quick, time saving and energy saving；Meanwhile, non-
Often it is suitable for having runed the old circulating water pipeline transformation of generating plants.
