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
The present invention relates to relate to F16L pipe, pipe joint or pipe fitting, method for maintaining technology, especially be with water, band to press the instantaneous leaking-stopping technology under the situation of fiber reinforced plastic pipe experience abnormal spoilage.
Background technique
In the known technology, heat-resisting, freeze proof, the wear-resisting good pressure-resistant performance of fiber reinforced plastic pipe and having from heavy and light, intensity height, plurality of advantages such as easy transportation and installation, maintenance cost are low, be widely used in engineering construction field, but in use often because the construction of other underground engineering, construction of structures causes the artificial or mechanical damage of buried fiber reinforced plastic pipe.Traditional craft leakage mending method is general adopt the discharging of fiber reinforced plastic pipe inner fluid finish the back anhydrous, do not have the artificial winding of carrying out glass fibre and polyester resin under the situation of pressing, not having other fluid and paste, polyester resin must could solidify under dry environment otherwise can not paste mending-leakage.But anhydrous, nothing presses the shortcoming that manually pastes craft leakage mending method obvious:
1, water stopping time is long, and the more big water stopping time in mouth of pipe footpath is more long, approximately about 1-3 days.
2, pipeline inner fluid discharging difficulty, indivedual places are discharged by environment and spatial constraints nowhere, namely enable discharging and also can cause the tube fluid wasting of resources.
3, this pipe-line system is stopped transport substantially in the discharge process, brings to a great extent loss and inconvenience for production, life.
Correlation technique discloses less, as:
Number of patent application number of patent application 200710300058 quick leak stopping adhesive tape of glassfiber for repairing pipes are a kind of leakage stopping technologies, and it is according to certain proportioning, make by certain technology by some industrial chemicals.Number of patent application 200720125267 discloses a kind of combustion gas pipe racks gas leak stopping holding device, comprises the pipeline fixing clamp, and described pipeline fixing clamp is made of the fixing clamp matrix and the fixing clamp movable block that flexibly connect, on the fixing clamp movable block, is provided with tapped hole; Afterburning clamp lever is provided with outside thread, and the outside thread on the afterburning clamp lever matches with tapped hole, and afterburning clamp lever is connected in the screw of fixing clamp movable block; At afterburning clamp lever afterburning handle is set.
Summary of the invention
The purpose of this invention is to provide a kind of at damaged fiber reinforced plastic pipe band water, band pressure instantaneous leaking-stopping method of construction.
Goal of the invention of the present invention realizes by following technical measures: to damaged mouthful on the Glass Steel Tube, make cushion rubber, adopt semicircle glass fibre reinforced plastics water shutoff band to be close to cushion rubber, form the repaired mouth stiffening plate, a close pulling force euphroe of each cuff of dual-side seal wear mouth hole outside glass fibre reinforced plastics water shutoff band, adopt the carefully and neatly done circle of people to twine in Glass Steel Tube repaired mouth stiffening plate middle and stick with paste repaire belt glass fibre alkali-free woven roving and unsaturated polyester resin, solidify and reach bearing capacity until repaire belt; Two ends, the left and right sides, the repaired mouth place pulling force euphroe of loosening respectively; End, the ready-made repaire belt left and right sides twines respectively and sticks with paste glass fibre alkali-free woven roving and unsaturated polyester resin is cured as one until new formation repaire belt in the centre.
The invention has the beneficial effects as follows: band water, pressure sealing under the situation of fiber reinforced plastic pipe experience abnormal spoilage, especially can overcome difficulties such as being subjected to season, weather, operation place and spatial constraints, guaranteeing that broken pipe normally moves under the prerequisite of use, rapidly and efficiently finish the Glass Steel Tube pipeline leakage stopping.Cost of labor and tube fluid waste of material that traditional blocking method produces have been reduced.
Description of drawings
Fig. 1 is scheme of installation of the present invention
Reference character: Glass Steel Tube 1, pulling force euphroe 2, fastening device 3, cushion rubber 4, damaged mouthful 5, stiffening plate 6, repaire belt 7.
Embodiment
To damaged mouthful 5 on the Glass Steel Tube 1, make cushion rubber 4, adopt semicircle glass fibre reinforced plastics water shutoff band to be close to cushion rubber 4, form repaired mouth stiffening plate 6, close pulling force euphroe of each cuff of dual-side 2 seal wear mouths 5 holes outside glass fibre reinforced plastics water shutoff band, adopt the carefully and neatly done circle of people to twine in Glass Steel Tube 1 repaired mouth stiffening plate 6 middles and stick with paste glass fibre alkali-free woven roving and unsaturated polyester resin, solidify and reach bearing capacity until repaire belt 7; Damaged mouthful of two ends, the left and right sides, the 5 place pulling force euphroe 2 of loosening respectively; End, ready-made repaire belt 7 left and right sides twines respectively and sticks with paste glass fibre alkali-free woven roving and unsaturated polyester resin is cured as one until new formation repaire belt 7 in the centre.
Specifically, to damaged mouthful 5 on the Glass Steel Tube 1, be made into 3-4 road disjunctor cushion rubber 4 with ethylene-propylene diene copolymer, adopt the semicircle glass fibre reinforced plastics water shutoff band of wall thickness 10-25mm to be close to cushion rubber 4, form repaired mouth stiffening plate 6, the outer cuff 2 road pulling force euphroes of glass fibre reinforced plastics water shutoff band are positioned at damaged mouthful 5 both sides, adopt fastening pulling force euphroe 2 seal wear mouths 5 holes, there is not the fluid leaks phenomenon until damaged mouthful 5 places, adopt whole circle to twine in stiffening plate 6 middles and stick with paste 04 type glass fibre alkali-free woven roving and unsaturated polyester resin repaire belt 7, solidify and reach the bearing capacity of 2.5mPa until repaire belt 7, damaged mouthful of (5) left and right sides pulling force euphroe 2 of loosening respectively, twine respectively and stick with paste 04 type glass fibre alkali-free woven roving and unsaturated polyester resin solidifies until new system repaire belt 7 making repaire belt 7 left and right side places, reach best repaired mouth mending-leakage effect.
Be applicable to Glass Steel Tube 1 internal diameter at DN150～DN2000, pressure is at 0.25Mpa～2.0Mpa, rigidity: 2500N/m
