Abstract
The utility model relates to an underground-to-overground section fuel gas inlet pipe with an anticorrosion reinforced layer, which comprises an underground-to-overground section fuel gas inlet bent pipe and is characterized in that the excircle surface of the inlet bent pipe is provided with a resin material reinforced layer, a polyethylene film layer, an adhesive tape layer and an anti-aging coating layer sequentially. The utility model has the advantages that the underground-to-overground section fuel gas inlet pipe has double functions of corrosion prevention and structure reinforcement on a fuel gas pipeline led into the room from outside, does not need to stop gas supply in the construction process, is simple to operation and can prolong the service life of the existing pipeline by 10 to 15 years; the construction is safe; the repair time is short; and both the mechanical property and the chemical corrosion resistance of a formed protective sleeve can meet the design requirements of the original pipeline.
Description
Technical field
The utility model belongs to the gas supply pipe line of registering one's residence, and relates in particular to the indoor ground that has anticorrosion reinforced layer of a kind of outdoor introducing down to ground section gas service pipe.
Background technique
At present, the corrosion fuel tube method in the gas industry processing gas supply pipe line generally is to adopt 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.This operational method directly influences user's gas for domestic use.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.Particularly outdoor introducing is more perishable down to the burning line of ground section indoorly.This section normally carries out before it carries out bend pipe from the preservative treatment of underground introducing bend pipe of drawing, and wears so rust appears in inlet tube bending part behind the bend pipe easily.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.Still adopt the replace tubes method to solve a pipeline corrosion difficult problem for a long time, so the operation of must stopping the supple of gas or steam directly influences user's daily life.
The model utility content
The utility model is in order to overcome deficiency of the prior art, provide a kind of ground of anticorrosion reinforced layer that has down to ground section gas service pipe, solved the corrosion problem of ground, prolonged the life-span of gas pipeline, avoided frequently changing pipeline down to ground section gas service pipe.
The utility model for achieving the above object, be achieved through the following technical solutions: a kind of ground of anticorrosion reinforced layer that has is down to ground section gas service pipe, introduce bend pipe down to section combustion gas on the ground, it is characterized in that: described introducing bend pipe outer round surface is provided with resin material reinforced layer, polyethylene film layer, viscose glue belt and antiaging coating layer successively with comprising.
Described introducing bend pipe and underground gas air inlet straight tube connecting end are provided with the larynx hoop and seal.
The utility model beneficial effect: can after shop-fabricated, install to the job site.Reparation for old pipeline can play a role equally.Leading fuel gas pipe-line from outdoor to indoor is played anticorrosion and structure strengthen double action, need not stop the supple of gas or steam during construction, simple to operate, can prolong the 10-15 in working life of existing pipeline.Construction safety, repair time are short, and the protection tube mechanical property of formation, resistance to chemical corrosion all can satisfy the designing requirement of former pipeline.

Fig. 2 is the leading fuel gas pipe-line from outdoor to indoor connection diagram.
Embodiment
Below in conjunction with preferred embodiment, details are as follows to embodiment that foundation the utility model provides:
Bend pipe 1 is introduced down to section combustion gas on the ground down to ground section gas service pipe in a kind of ground that has anticorrosion reinforced layer with comprising, and described introducing bend pipe outer round surface is provided with resin material reinforced layer 2, polyethylene film layer 3 and viscose glue belt 4 and antiaging coating layer 7 successively.Described introducing bend pipe and underground gas air inlet straight tube 6 connecting ends are provided with the larynx hoop and seal 5 and seal with underground gas air inlet straight tube by the larynx hoop and to be connected.Introducing bend pipe has one section light pipe 8 with the vertical tube of combustion gas on the ground connecting end, is connected by adpting flange with ground combustion gas vertical tube or welds, and wraps up anticorrosive coat again.
For the reparation of old pipeline, construction sequence is:
(1) pretreatment of grooving and corrosion pipe
To introduce the bend pipe surface and do processing of rust removing, expose new metal covering;
(2) prefabricated sleeve pipe, enhancing perfusion resin adhesive liquid
Be rolled into tubulose with geotextiles greater than the transverse tube diameter, in the standpipe place of the introducing bend pipe of removing old anticorrosive coat and rust cleaning parcel geotextiles, geotechnological stringing is taken mouth and vertically formed pipe box with rubber belt sealing along it, the geotextiles pipe box was pushed away the curved section of introducing bend pipe to be located and is responsible for former anticorrosive coat with underground horizontal combustion gas for 30 centimeters to join, with larynx hoop chucking interface, again wrap up the pipe box that geotextiles makes and the geotextiles pipe box of curved section again at the standpipe place and link into an integrated entity, several times the glue for preparing from high-end injection, dipping evenly, solidify;
(3) repairing and reinforcement surface treatment
After the perfusion glue is treated to solidify fully, a horizontal transverse tube or a rust proof paint of introducing bend pipe brush, twice finish paint.
During repairing and reinforcement, if find that through rust cleaning, when removing old pitch anticorrosive coat pipeline has point-like to bore a hole and does repairing and reinforcement again after the rapid-result steel quick blocking.Potting compound ripple when construction end opening injecting glue that horizontal wall-passing pipe is high, horizontal transverse tube and introducing bend pipe glue cured layer thickness should be not less than 1.5mm.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
Claims (2)
1. a ground that has anticorrosion reinforced layer is down to ground section gas service pipe, introduce bend pipe down to section combustion gas on the ground, it is characterized in that: described introducing bend pipe outer round surface is provided with resin material reinforced layer, polyethylene film layer, viscose glue belt and antiaging coating layer successively with comprising.
2. the ground that has anticorrosion reinforced layer according to claim 1 is down to ground section gas service pipe, and it is characterized in that: described introducing bend pipe and underground gas air inlet straight tube connecting end are provided with the larynx hoop and seal.
