Abstract
The utility model discloses a water pipe for discharging underground sewage. The water pipe comprises a pipe body, an anti-corrosion inner wall layer, a flexible anti-pressure filled layer, an anti-freezing and 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-pressure filled layer wraps the outer surface of the pipe body. The anti-freezing and anti-crack layer wraps the flexible anti-pressure filled layer. The anti-aging outer covering layer wraps the anti-freezing and anti-crack layer. The water pipe is good in anti-corrosion performance and high in anti-impact capacity, anti-aging performance and anti-freezing and anti-crack performance, and can not be corroded by microorganisms, acid, alkaline and oil in sewage and waste water.
Description
Technical field
The utility model relates to the pipe fitting field, particularly relates to a kind of water pipe for underground sewer.
Background technique
In industry and city, usually adopt now the concrete blow-off line, often contain a large amount of different types of microorganisms in sewage, because microbial metabolism causes concrete corrosion, be called concrete microbiologic(al) corrosion.Microbiologic(al) corrosion can cause concrete structural surface mortar in sewage transport and treatment facility to come off, 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 affected the allomeric function in city, and rebuilds or keep in repair and also will expend huge resource and financial resources.Be badly in need of proposing a kind of corrosion resistance strong: anticorrosive good, the anti-outer power of hitting is strong, and ageing-resistant performance is strong, the sewage pipe of antifreeze cracking resistance.
The model utility content
The technical problem that the utility model mainly solves is to provide a kind of anticorrosive good, can be by corrosion such as the microorganism in sewage and waste water, soda acid and oil contents; The anti-outer power of hitting is strong, and ageing-resistant performance is strong, the water pipe for underground sewer that antifreeze cracking resistance is good.
For solving the problems of the technologies described above, the technological scheme that the utility model 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 preferred embodiment of the utility model, described tube body is concrete pipe.
In preferred embodiment of the utility model, the thickness of described flexible resistance to compression packed layer is 1 ~ 3 mm.
In preferred embodiment of the utility model, described antifreeze crack-resistant layer is the antifreeze anti-crack fiber layer of polypropylene.
The beneficial effects of the utility model are: the utility model is anticorrosive good, can be by corrosion such as the microorganism in sewage and 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 accompanying drawing explanation
Fig. 1 is the structural representation of the utility model for water pipe one preferred embodiment of underground sewer;
In accompanying drawing, the mark of each parts is as follows: 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 utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Refer to Fig. 1, the utility model is embodiment comprise:
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 utility model is anticorrosive good, can be by corrosion such as the microorganism in sewage and 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 foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
