Abstract
A composite anti-corrosion drain pipe is characterized in that the drain pipe comprises a pipe body made of inorganic materials. An anti-corrosion high molecular material layer is attached into the pipe body made of inorganic materials, and the anti-corrosion high molecular material layer is embedded and fixed with the inner wall of the pipe body made of inorganic materials. The composite anti-corrosion drain pipe is reasonable in structural design, good in anti-corrosion performance and long in service life and can effectively eliminate traction force generated by a water flow along the direction of the pipe body, improve the combination tightness and strength of the anti-corrosion high molecular material layer and the pipe body made of inorganic materials, and further effectively prolong service life of the anti-corrosion high molecular material layer and reduce using cost.
Description
Technical field
The utility model belongs to logical draining and uses pipeline, the concrete composite anti-corrosive waste pipe that relates to a kind of plumbing use.
Background technique
In the existing technology, mostly the discharge pipe line that is used for city, rural area and water conservancy projects etc. is the inorganic material pipeline of reinforced concrete material, perhaps is the straight-tube shape pipeline of ceramic structure.The cost cost of such pipeline is low, and body is sturdy and durable, the arterial drainage pipeline of written city, road, water conservancy projects etc.But because inorganic material pipeline self characteristics, for example inner tube wall is more coarse, pipeline inner fluid resistance is big, and the draining flow velocity is slow and easy sedimentary pile deposition is husky.The corrosion resistance of particularly existing inorganic material pipeline is relatively poor; The rainwater that causes along with atmosphere environment is acid increase and draining in the acid and alkali substance that dissolves increase; This has caused such pipeline to be easy to the reduction in strength problem that inside is corroded and is caused in use occur, thereby has cut down greatly the working life of discharge pipe line.
On March 3rd, 2010, disclosed Chinese patent ZL200920009190.8 provided a kind of reinforced concrete sewer pipe of composite anti-corrosive; The main body of this waste pipe is the hollow body of concrete or reinforced concrete; The ganoid antiseptic rubber of having applied ointment or plaster on the inwall of this hollow smooth body; The inwall of this hollow body offers some roads groove, fills out in the groove to be covered with antiseptic rubber and to be linked to be integral body with ganoid antiseptic rubber.The rigidity intensity of this waste pipe is high, the resistance to compression load is big, inwall frictional force is little, corrosion resistance and good, long service life.But the defective of this reinforced concrete sewer pipe is that the water yield direction retention force of antiseptic rubber inner core is less, and its rubber inner core causes occurring lateral fault because stretch easily, thereby influences its using effect under the effect of the tractive force that water (flow) direction produces.
The model utility content
The utility model provides that a kind of reasonable in design, antiseptic property are good, the composite anti-corrosive waste pipe of long service life; It can effectively eliminate the tractive force of the body direction of current generation; That improves anticorrosion polymer material layer and inorganic material body combines compact type and adhesive strength; Thereby prolong the working life of anticorrosion polymer material layer effectively, reduce user cost.
The technological scheme that the utility model adopted is following:
A kind of composite anti-corrosive waste pipe is characterized in that said waste pipe comprises an inorganic material body, the anticorrosion polymer material layer of fitting in this inorganic material body, and the inwall setting-in of said anticorrosion polymer material layer and inorganic material body is fixed.
In the embodiment; Said inorganic material body is concrete, reinforced concrete or ceramic structure body; The helical groove that its inwall is provided with pit or extends along the body length direction, the outer wall of said anticorrosion polymer material layer cooperates with said pit or helical groove setting-in.
In one mode of execution, said pit distribution is on the inwall of inorganic material body, and this pit is turbination or inverted ladder-shaped body structure.
In another mode of execution, said helical groove is the groove of rectangular cross-section, and the outer wall of said anticorrosion polymer material layer is provided with the convexity corresponding with said helical groove, and this groove is fixed with the protruding setting-in that cooperates.
In the mode of execution, said anticorrosion polymer material layer is an elastic rubbery body again, and its inwall is a smooth structure.
This composite anti-corrosive waste pipe adopts the inwall setting-in means of fixation of anticorrosion polymer material layer and inorganic material body when adopting inorganic material outer tube body and inside lining anti-corrosive polymer material layer, improved the combination fastness of the two.Pit along inorganic material inboard wall of tube body distributed and arranged can effectively improve anticorrosion polymer material layer and the bonding tightness of misreading the material inboard wall of tube body; It is more important that what be is for anticorrosion polymer material layer uniform traction friction to be provided; The tractive force of the body direction of eliminating flowing water effectively and being brought; Thereby improved the stressed dispersive property of anticorrosion polymer material layer, thereby prolonged working life.This pit more can adopt helical groove to replace; Helical groove is along the spiral inner wall distributed and arranged of inorganic material body; The outer wall of anticorrosion polymer material layer is fixed in this groove through the setting-in mode; Can effectively improve the flowing water tractive force that combines fastness and eliminate the body direction, thereby more can reduce the thickness of anticorrosion polymer material layer effectively, reduce manufacture cost.
The beneficial effect of the utility model is; This composite anti-corrosive drain structure is reasonable in design, antiseptic property is good, long service life; It can effectively eliminate the tractive force of the body direction of current generation; That improves anticorrosion polymer material layer and inorganic material body combines compact type and adhesive strength, thereby prolongs the working life of anticorrosion polymer material layer effectively, reduces user cost.
Below in conjunction with accompanying drawing and embodiment the utility model is done further elaboration.
