Abstract
The invention discloses a water pipe for discharging sewage underground. The water pipe comprises a pipe body, an anti-corrosion inner wall layer, a flexible anti-crush filling layer, an anti-freezing anti-crack layer and an anti-aging outer covering layer. The anti-corrosion inner wall layer is arranged on the inner surface of the pipe body, the flexible anti-crush filling layer coats the outer surface of the pipe body, the anti-freezing anti-crack layer coats the outer portion of the flexible anti-crush filling layer, and the anti-aging outer covering layer coats the outer portion of the anti-freezing anti-crack layer. The water pipe is good in anti-corrosion performance, cannot be corroded by microorganisms, acid-base, oil and the like in the sewage and waste water, and is strong in outside strike force resistance performance, strong in anti-aging performance, and good in anti-freezing and anti-crack performance.
Description
Technical field
The present invention relates to the pipe fitting field, particularly relate to a kind of water pipe for underground sewer.
Background technique
Usually adopt the concrete blow-off line now in industry and the city, often contain a large amount of different types of microorganisms in the sewage, because microbial metabolism causes concrete corrosion to be called concrete microbiologic(al) corrosion.Microbiologic(al) corrosion can cause that the concrete structural surface mortar comes off in sewage transport and the treatment facility, and aggregate exposure can produce cracking and corrosion of steel bar when serious, thereby its service life is shortened greatly.This has not only directly influenced the allomeric function in city, and rebuilds or keep in repair and also will expend huge resource and financial resources.It is strong to be badly in need of proposing a kind of corrosion resistance: anticorrosive good, the anti-outer power of hitting is strong, and ageing-resistant performance is strong, the sewage pipe of antifreeze cracking resistance.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of anticorrosive good, can be by corrosion such as the microorganism in sewage and the waste water, soda acid and oil contents; The anti-outer power of hitting is strong, and ageing-resistant performance is strong, the water pipe that is used for underground sewer that antifreeze cracking resistance is good.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of water pipe for underground sewer is provided, comprise tube body, anticorrosive inner wall layer, flexible resistance to compression packed layer, antifreeze crack-resistant layer and ageing-resistant surrounding layer, described tube body internal surface is provided with described anticorrosive inner wall layer, described tube body outer surface is wrapped in described flexible resistance to compression packed layer, described flexible resistance to compression packed layer outer wrapping described antifreeze crack-resistant layer, and described antifreeze crack-resistant layer outer wrapping described ageing-resistant surrounding layer.
In a preferred embodiment of the present invention, described tube body is concrete pipe.
In a preferred embodiment of the present invention, the thickness of described flexible resistance to compression packed layer is 1 ~ 3 mm.
In a preferred embodiment of the present invention, described antifreeze crack-resistant layer is the antifreeze anti-crack fiber layer of polypropylene.
The invention has the beneficial effects as follows: the present invention is anticorrosive good, can be by corrosion such as the microorganism in sewage and the waste water, soda acid and oil contents; The anti-outer power of hitting is strong, and ageing-resistant performance is strong, and antifreeze cracking resistance is good.
Description of drawings
Fig. 1 is the structural representation that the present invention is used for water pipe one preferred embodiment of underground sewer;
The mark of each parts is as follows in the accompanying drawing: 1, tube body, 2, anticorrosive inner wall layer, 3, flexible resistance to compression packed layer, 4, antifreeze crack-resistant layer, 5, ageing-resistant surrounding layer.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
See also Fig. 1, the embodiment of the invention comprises:
A kind of water pipe for underground sewer, comprise tube body 1, anticorrosive inner wall layer 2, flexible resistance to compression packed layer 3, antifreeze crack-resistant layer 4 and ageing-resistant surrounding layer 5, described tube body 1 internal surface is provided with described anticorrosive inner wall layer 2, described tube body 1 outer surface is wrapped in described flexible resistance to compression packed layer 3, described flexible resistance to compression packed layer 3 outer wrapping described antifreeze crack-resistant layer 4, and described antifreeze crack-resistant layer 4 outer wrapping described ageing-resistant surrounding layer 5.
In addition, described tube body 1 is concrete pipe.
In addition, the thickness of described flexible resistance to compression packed layer 3 is 1 ~ 3 mm.
In addition, described antifreeze crack-resistant layer 4 is the antifreeze anti-crack fiber layer of polypropylene.
The present invention is anticorrosive good, can be by corrosion such as the microorganism in sewage and the waste water, soda acid and oil contents; The anti-outer power of hitting is strong, and ageing-resistant performance is strong, and antifreeze cracking resistance is good.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
