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); coating and clamping tension tighten devices (2) by using the outer ring of the fiberglass water sealing belt to seal an opening of the damaged mouth (5); winding and pasting fiberglass alkali-free roving cloth and unsaturated polyester resin 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 at both left and right ends at the repaired mouth; 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 repaired mouth until the mouth-repairing area is solidified. The rapid plugging method is used for plugging the fiberglass pipeline, damaged in an abnormal-damaged condition, with the water and the pressure. On the premise of ensuring the normal operation of the damaged pipeline, the fiberglass pipeline is plugged rapidly and efficiently, thereby reducing the labor cost and the waste of fluid material in the pipeline which are generated by the traditional plugging method.
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 GRP pipe experience abnormal spoilage.
Background technique
In the known technology; Heat-resisting, freeze proof, the wear-resisting good pressure-resistant performance of GRP pipe and have from heavy and light, intensity high; 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 GRP pipe.Traditional craft leakage mending method generally adopt GRP pipe inner fluid discharging finish the back anhydrous, do not have the manual work of carrying out glass fibre and polyester resin under the situation of pressing, not having other fluid and twine and paste, polyester resin must could solidify under dry environment otherwise can not paste mending-leakage.But anhydrous, do not have to press the artificial shortcoming that pastes craft leakage mending method obvious:
1, water stopping time is long, and the big more water stopping time in mouth of pipe footpath is long more, approximately about 1-3 days.
2, pipeline inner fluid discharging difficulty, indivedual places are discharged by environment and spatial limitation nowhere, promptly enable discharging and also can cause the tube fluid wasting of resources.
3, this pipe-line system is stopped transport basically in the discharge process, gives and produces, lives and bring loss and inconvenience to a great extent.
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, process through certain process 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 up 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; Afterburning handle is set on afterburning clamp lever.
Summary of the invention
The purpose of this invention is to provide a kind of to damaged GRP pipe band water, band pressure instantaneous leaking-stopping method of construction.
Goal of the invention of the present invention realizes through 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, cover hoop tension euphroe seal wear mouth hole, glass fibre reinforced plastics water shutoff band outer ring; Adopt the carefully and neatly done circle of people to twine in Glass Steel Tube repaired mouth stiffening plate middle and stick with paste glass fibre alkali-free woven roving and unsaturated polyester resin, solidify and reach bearing capacity until repaire belt; The repaired mouth place right ends pulling force euphroe of loosening respectively; Twining paste glass fibre alkali-free woven roving and unsaturated polyester resin respectively in end, the repaire belt left and right sides solidifies until repaire belt.
The invention has the beneficial effects as follows: band water, pressure sealing under the situation of GRP pipe experience abnormal spoilage; Especially can overcome difficulties such as receiving season, weather, operation place and spatial limitation; Guaranteeing that broken pipe normally moves under the prerequisite of use completion Glass Steel Tube pipeline leakage stopping rapidly and efficiently.Cost of labor that traditional blocking method produced and tube fluid waste of material have been reduced.
Description of drawings
Fig. 1 is a 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, cover hoop tension euphroe 2 seal wear mouths 5 holes, glass fibre reinforced plastics water shutoff band outer ring; 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; The repaired mouth place right ends pulling force euphroe of loosening respectively; Twining paste glass fibre alkali-free woven roving and unsaturated polyester resin respectively in end, repaire belt 7 left and right sides solidifies until repaire belt.
Specifically, the damaged mouth 5 on the Glass Steel Tube 1 is made into 3-4 road disjunctor O-ring seal 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 O-ring seal 4; Form repaired mouth stiffening plate 6, cuff 2-3 road, glass fibre reinforced plastics water shutoff band outer ring pulling force euphroe adopts fastening pulling force euphroe 2 seal wear mouths 5 holes; There is not the fluid leaks phenomenon until Glass Steel Tube 1 and repaired mouth place thereof; 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, until repaire belt 7 curing and reach the bearing capacity of 2.5mPa, the repaired mouth place right ends pulling force euphroe 2 of loosening respectively; Twine paste 04 type glass fibre alkali-free woven roving and unsaturated polyester resin in end, repaire belt 7 left and right sides respectively and solidify, reach best repaired mouth mending-leakage effect until repaire belt 7.
