The service life of native pipe is short, later maintenance cost is high.The shortcomings that pipe of concrete is not corrosion-resistant is directed in the industry at present, frequently with high score
Sub- material is as inner lining structure to reduce being corroded for pipe of concrete.
Utility model patent CN201428867Y is reported " reinforced concrete sewer pipe with PVC corrosion protective linings ".Patent
Pipe of concrete and corrosive substance are isolated by increasing by one layer of PVC corrosion-proof lining, so as to play the work of protection pipe of concrete
With.But the corrosion-proof lining has certain defect, i.e. the bond strength of the T-shaped fixture and concrete layer of PVC liners is not high enough,
In the presence of the hidden danger for being layered, coming off, so as to influence the protective effect to body.
By pertinent literature and patent report, the structure design of corrosion-proof lining is used more to the protected working of pipe of concrete,
But, this protected working to pipe of concrete very few for corrosion-proof lining and the consideration and design work of concrete layer bond strength
Have a greatly reduced quality, it is necessary to carry out corresponding technical support.
Utility model content
The purpose of this utility model is exactly a kind of with enhancing in order to be provided the defects of overcoming above-mentioned prior art to exist
The pipe of concrete of anchor structure liner plastic sheet.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of pipe of concrete with enhancing anchor structure liner plastic sheet, including the liner with enhancing anchor structure
Plastic sheet and the concrete being wrapped on the outside of liner plastic sheet, described enhancing anchor structure is in del,
The enhancing anchor structure is extend into concrete so that liner plastic sheet and concrete strong bonded, is resisted
Pull out intensity height.
Along liner plastic sheet length direction, described enhancing anchor structure interval 5cm-20cm arrangements, and along lining plastic
Film material is circumferential, and described enhancing anchor structure is intervally arranged.
Described enhancing anchor structure is made up of linkage section and anchoring section, and described linkage section and liner plastic sheet are direct
Be connected, described anchoring section is joined directly together with linkage section, anchoring section be contacted with concrete and with liner plastic sheet
Parallel part.
Described linkage section is in del, and both sides of the chest are respectively present 30 ° -90 ° of inclination angle with liner plastic sheet plane
Degree.
Described linkage section is highly 5mm-15mm, thickness 2mm-6mm.
Described linkage section center line is vertical with liner plastic sheet surface.
Described anchoring section shape includes rectangle, semicircle or half elliptic.
Described enhancing anchor structure can also be the shaped pieces such as decussate texture, M shape structure or mushroom construction.
Described concrete includes but is not limited to concrete reinforced pipe, pipe of cement, prestressed pipe etc.；Purposes includes
But it is not limited to drainpipe, feed pipe, shield structure etc..
Described liner plastic sheet is prepared by polymer plastic glue material, described polymer plastic glue material by PE,
One or more of compositions in PVC, thermoplastic elastomer (TPE), polyurethane or rubber etc..
In the utility model, unique enhancing anchor structure than traditional T-shaped anchor structure have higher contact area with more
Strong tensile strength, higher contact area add interface friction force, " inverted-triangular " anchor structure add pulling test strength and
Non-deformability, finally peel off, come off so as to avoid occurring loosening between inner liner and pipe of concrete during long-term use.
In the utility model, liner plastic sheet is high polymer material, have it is corrosion-resistant, ageing-resistant, service life is long, defeated
The features such as water is big, effectively extend pipe of concrete service life 10-20 and reduce regular maintenance expense and water delivery into
This.
Compared with prior art, the utility model has with reference to good sealing effect, service life length, favorable anti-corrosion effect, dimension
The advantages of cost is low is protected, the pipe of concrete 10-20 life-spans can be obviously prolonged.
