Abstract
The invention relates to a repair reinforcing means of the indoor fuel gas pipeline from the outdoor, characterized in that, the construction procedure is preprocessing, derusting process; rolling into the tube with the diameter bigger than that of the fuel gas tube with the earth work cloth; preprocessing the sleeve, adopting the special pressurzing extruder gun to inject the bedded glue liquor from the relative high end of the construction grade, for even dipping and curing; repairing and reinforcing the surface treatment with one time of antirust paint and two times of top coat. The invention has the following advantages: performing the action of the corrosion protection and structure reinforce on the indoor fuel gas pipeline from the outdoor, simple operation, long service life.
Description
Technical field
The invention belongs to band and press corrosion pipeline recovery technique, relate in particular to a kind of restoring and fastening method of leading fuel gas pipe-line from outdoor to indoor.
Background technique
At present, corrosion fuel tube generally adopts the replace tubes method.This operational method is carried out after must stopping the supple of gas or steam, and suppresses after changing end conduit again, the igniting of could ventilating after qualified.Directly influence user's life.Corrosion failure appears again in the new pipe of just having changed after several years.Make gas burning system exist the hidden danger of detonation.The inventor once applied for a patent (the patent No.: ZL97119962.0) disclose a kind of restoring and fastening method that is used for indoor gas pipeline, be mainly used in the reparation of indoor fuel gas pipeline.Because indoor pipeline is a Vertical direction, the glue of perfusion relies on its gravity flow more evenly to flood when repairing.Leading fuel gas pipe-line from outdoor to indoor comprises: (1) is from the underground horizontal transverse tube of combustion gas of drawing in Stall body of wall inlet chamber, because its horizontal transverse tube is not done any processing between the body of wall sleeve pipe, year in and year out under multiple etching condition effects such as kitchen high temperature, damp and hot, oil gas and rainwater, cause the serious corrosion of the horizontal transverse tube outer wall of introducing, its corrosion penetration can reach 1-2mm until perforation; (2) introduce bend pipe from the underground back of stretching out near the combustion gas on ground, because its ageing of asphalt anticorrosive coat cracking, rainwater can invade in the anticorrosive coat or also can destroy the anticorrosive coat of introducing bend pipe near the place, ground when sub-district ground construction black top oil, causes new pipe only to move and promptly corrosion or phenomenon of rupture can occur behind the 8-10.In addition, normally before bend pipe, carry out, wear so rust appears in inlet tube bending part behind the bend pipe easily from the preservative treatment of underground introducing bend pipe of drawing.Because the restoring and fastening method of indoor gas pipeline can not satisfy the technological requirement of outdoor gas pipeline, still adopts the replace tubes method for a long time, directly influences user's daily life.
Summary of the invention
The present invention is in order to overcome deficiency of the prior art, a kind of restoring and fastening method of leading fuel gas pipe-line from outdoor to indoor is provided, the outdoor introducing indoor fuel gas of repairing and reinforcement pipeline can stop the supple of gas or steam, be with to press and construct, utilization enhancing perfusion glue method guarantees that dipping evenly, prolongs the life-span of gas pipeline.
The present invention is achieved through the following technical solutions for achieving the above object: a kind of restoring and fastening method of leading fuel gas pipe-line from outdoor to indoor is characterized in that: construction sequence is:
