Abstract
A perforation leakage mending method of a water line under pressure comprises choosing a nut whose bore diameter is approximately equal to the diameter of a perforation, welding the nut on the water line, taking a screw which is matched with the nut to revolve into the nut and to be fixed tightly, then welding the screw and the nut, which guarantees the mending of the water line after perforating under the normal water supply condition, and enables the water line to work normally.
Description
Technical field
The present invention relates to a kind of water pipeline craft leakage mending method, especially a kind of craft leakage mending method with the setting-out pipeline.
Background technique
Water pipeline perforation back mending-leakage has multiple way, mainly is divided into the cut off the water mending-leakage and the mending-leakage of not cutting off the water.The mending-leakage of cutting off the water is the simplest also common, such as electric welding, gas welding, check card or add EXPANSION ANCHOR BOLTS etc. toward perforation place.But water supply line is because need of work sometimes, in the time of can not stopping supplying water, obvious above-mentioned way is just inapplicable, and is less for pressure of supply water, and the little water pipeline of boring a hole can be blocked with timber, interim emergent, but not safe solution after all, when welding, because current are arranged with electrogas welding, always can not mend fully sternly, always occur aperture at last and leak outward.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned technology and a kind of band setting-out pipeline perforation craft leakage mending method is provided.
The object of the present invention is achieved like this: the water pipeline site of perforation is tied with polishing machine, selects a nut aperture and the suitable substantially nut of penetration hole diameter, then nut bore is alignd with perforation, and nut is welded on the waterpipe; Get again with the supporting bolt precession nut of nut after, fastening, again bolts and nuts are welded, with the polishing machine sanding of flat of the weld seam between nut and bolt, brush rust proof paint at last.
Compared with prior art, advantage of the present invention is: easy construction is simple to operate, and cost is low, guarantees that the water pipeline after the perforation can be mended under the situation of normal water supply sternly fully, makes water pipeline recover proper functioning.
Description of drawings
Fig. 1 is for perforation pipeline schematic representation occurring.
Fig. 2 is at pipeline perforation place welded nut structural representation.
Fig. 3 has welded bolts and nuts line construction schematic representation.
Embodiment
A kind of band setting-out pipeline perforation craft leakage mending method comprises perforation water pipeline, nut, bolt, weld seam.After perforation 2 appears in water pipeline 1, earlier site of perforation is tied with polishing machine, be convenient to next step welding, select a nut 3, the aperture that changes nut 3 is suitable substantially with perforation 2 diameters, then nut 3 holes is faced toward perforation 2, nut 3 is welded on the waterpipe, notices that weld seam 4 must be tight; It is fastening to get the supporting bolt of nut 35 precession nuts 3 backs again, amputate being higher than the above bolt 5 of nut 3 about 3～5mm with saw then, again bolt 5 and nut 3 are welded,, have a look and brush rust proof paint after water-tight and get final product again weld seam 6 polishing machine sanding of flat between nut and bolt.
Claims (1)
1. be with setting-out pipeline perforation craft leakage mending method for one kind, it is characterized in that: the water pipeline site of perforation is tied with polishing machine, selects a nut aperture and the suitable substantially nut of penetration hole diameter, then nut bore is alignd with perforation, and nut is welded on the waterpipe; Get again with the supporting bolt precession nut of nut after, fastening, again bolts and nuts are welded, with the polishing machine sanding of flat of the weld seam between nut and bolt, brush rust proof paint at last.
