Abstract
The no-damage buried water pipe repairing method includes separating the water pipe from its connected branch pipes and water source pipe, blocking all the connecting ports while leaving two or several ports, blowing the inside with compressed air to dry, filling antiseepage glue, blowing the antiseepage glue with compressed air to cover the inner surface of the pipe, and drying the glue to form an antiseepage layer. The said repair process has no damage to available building and decoration, no building garbage produced, less engineering amount, low cost, complete antiseepage treatment and other advantages.
Description
Technical field: the no-damage repairing method that the present invention relates to a kind of water pipe leakage maintaining method, particularly buried water pipe.
Background technique: water pipe may seepage after long-term the use, and present maintenance method generally all is to manage to detect leak source, this section water pipe is cut off take out then, changes to new water pipe.If water pipe is embedded in the building in being, taking out old water pipe must destroy building wall and decoration, and engineering work load is big, can produce a large amount of constructional rubbishs, must decorate again after the maintenance, and the maintenance overall cost is increased greatly, and the engineering time prolongs.And buried water pipe determines that leak source is pretty troublesome, cuts off the installation process that old water pipe changes to new water pipe and can make other pipe section that is connected influenced, even make other pipe section produce new seepage.
Summary of the invention:, the invention provides a kind of no-damage repairing method for buried water pipe that does not damage existing building and decoration fully at the deficiencies in the prior art.
Method for maintaining of the present invention carries out successively according to following steps:
(a) close the watering of waiting to repair water pipe and being communicated with whole pipelines that arm forms, remove all water meters, the fire hose first-class annex of original current through the place after, the connection mouth of pipeline all with the plug sealing, is only stayed two or several inlet/outlet;
(b) import to pipeline continues to be blown into pressure air or hot blast, until whole pipe interior bone dry;
(c) inject the leakproof glue of water insoluble type to the import of pipeline, continue the charged pressure air again and make leakproof glue fully mobile at pipe interior, the amount of the leakproof glue of injection is each part of the whole inner-walls of duct of covering enough;
(d) repeating step (c) one or many;
(e) import to pipeline continues to be blown into pressure air, until cover the leakproof glue bone dry of inner-walls of duct;
(f) remove the plug of sealing, reinstall water meter, the first-class annex of the fire hose gets final product.
Adopt leakage maintaining method of the present invention, can not damage fully, can not produce constructional rubbish, reduced engineering work load, reduced the maintenance overall cost existing building and decoration.And the present invention need not accurately to measure leak source, accelerated processing rate, avoids water pipe to change influence and produces new seepage, and once maintenance can be prevented drain process to the whole whole pipelines that are connected.
The present invention is after injecting leakproof glue, the air pressure that charges into is flowed even as big as making the atomizing of leakproof glue, and time in turn is opened outlet in the different arms position of pipeline, make leakproof glue cover each branch pipe wall fully rapidly, leakproof glue can be more full and uniform in the inner-walls of duct distribution like this, and the utilization of leakproof glue is also more abundant.
When dry leakproof glue, also can open outlet at the different arms position of pipeline time in turn, make all arms all can be dry rapidly unimpeded like this, and can guarantee that each arm can not stopped up by leakproof glue.
Further specify the present invention below in conjunction with embodiment.
Embodiment: in the residential building of common a kitchen and a guard one balcony cover type, carry out the leakproof maintenance, carry out successively according to following steps:
(a) close the watering of dwelling house, remove all water meters, the fire hose first-class annex of original current through the place, can prevent that water meter etc. from being stopped up by leakproof glue, connection mouth with pipeline all seals with plug then, only stay two or several inlet/outlet, general needs an import and an outlet, is convenient to subsequent step and keeps air pressure;
(b) import to pipeline continues to be blown into pressure air, until whole pipe interior bone dry generally needs to continue can guarantee bone dry more than 24 hours;
(c) inject the leakproof glue of water insoluble type to the import of pipeline, continue the charged pressure air again and make leakproof glue fully mobile at pipe interior, the amount of the leakproof glue of injection is each part of the whole inner-walls of duct of covering enough, is generally about 3000 milliliters; If the air pressure that charges into is at 0.8Mpa, the pressure that promptly single-phase air compressor provides generally is enough to make the atomizing of leakproof glue to be flowed, and can opens outlet at the different arms position of pipeline time in turn, makes leakproof glue cover each branch pipe wall fully rapidly;
(d) repeating step (c) once, generally leakproof comprehensively;
(e) import to pipeline continues to be blown into pressure air, until cover the leakproof glue bone dry of inner-walls of duct, Dry run generally needs to continue more than 48 hours, also can open outlet when dry at the different arms position of pipeline time in turn, all drying is unimpeded rapidly to make all arms like this, and can guarantee that each arm can not stopped up by leakproof glue;
(f) remove the plug of sealing, reinstall water meter, the first-class annex of the fire hose gets final product.
After the leakproof maintenance, the pipe inner wall of whole connections of above-mentioned dwelling house all is coated with leakproof glue, and once maintenance can produce leak preventing effect to whole water pipes, and the efficient height does not damage metope and decoration.In fact, if desired, also can improve the effect of anti-drain process like this at the preceding cleaning liquid pipe blow-through that injects earlier of step (b).
The present invention not only can be used for general building buried water pipe maintenance, if choose suitable leakproof glue, and provides the gas of sufficient pressurising force, equally also can carry out the leakproof maintenance to municipal network water supply, and need not to excavate pavement maintenance influences traffic.
