Description
Technical field
The present invention relates to a kind of pipe of concrete structures, having enhancing anchor structure liner plastic sheet more particularly, to one kind
Pipe of concrete.
Background technology
Pipe of concrete use sewer or other with corrosivity in the environment of when, drainpipe can cure the corruption such as hydrogen
Corrosion gas pickling destroys, and pipe of concrete service life is caused to greatly shorten, or even causes engineering problem.Therefore, traditional coagulation
The service life of native pipe is short, later maintenance cost is high.The not corrosion-resistant disadvantage of pipe of concrete 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, to play the work of protection pipe of concrete
With.But there are certain defects for the corrosion-proof lining, i.e. the T-type fixing piece of PVC liners and the bond strength of concrete layer is not high enough,
In the presence of the hidden danger for being layered, falling off, to influence the protective effect to tube body.
By pertinent literature and patent report, the structure design of corrosion-proof lining is mostly used to the protected working of pipe of concrete,
But for corrosion-proof lining and very few with design work the considerations of concrete layer bond strength, this protected working to pipe of concrete
It has a greatly reduced quality, needs to carry out corresponding technical support.
Invention content
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind having enhancing anchoring
The pipe of concrete of structure liner plastic sheet.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of pipe of concrete with enhancing anchor structure liner plastic sheet includes the liner with enhancing anchor structure
Plastic sheet and the concrete being wrapped on the outside of liner plastic sheet, the enhancing anchor structure are in up-side down triangle,
The enhancing anchor structure is extend into concrete so that liner plastic sheet is strong bonded with concrete, resists
Pull out intensity height.
Along liner plastic sheet length direction, the enhancing anchor structure interval 5cm-20cm arrangements, and along lining plastic
Film material is circumferential, and the enhancing anchor structure is intervally arranged.
The enhancing anchor structure is made of linkage section and anchoring section, and the linkage section and liner plastic sheet are direct
Be connected, the anchoring section is connected directly with linkage section, anchoring section for contacted with concrete and with liner plastic sheet
Parallel part.
The linkage section is in up-side down triangle, and both sides of the chest are respectively present 30 ° -90 ° of inclination angle with liner plastic sheet plane
Degree.
The linkage section height is 5mm-15mm, thickness 2mm-6mm.
The linkage section center line is vertical with liner plastic sheet surface.
The anchoring section shape includes rectangle, semicircle or half elliptic.
The enhancing anchor structure can also be the shaped pieces such as decussate texture, M shape structure or mushroom construction.
The concrete includes but not limited to concrete reinforced pipe, pipe of cement, prestressed pipe etc.；Purposes includes
But be not limited to drainpipe, feed pipe, shield structure etc..
The liner plastic sheet is formed by high molecular weight plastic material preparation, the polymer plastic glue material by PE,
One or more of PVC, thermoplastic elastomer (TPE), polyurethane or rubber etc. form.
In the present invention, unique enhancing anchor structure than traditional T-type anchor structure have higher contact area with it is stronger
Tensile strength, higher contact area increase interface friction force, and " inverted-triangular " anchor structure increases pulling test strength and resistance
Shape ability is finally removed, is fallen off to avoid occurring loosening between liner layer and pipe of concrete during being used for a long time.
In the present invention, liner plastic sheet is high molecular material, with corrosion-resistant, ageing-resistant, service life is long, carrying capacity
The features such as big, effectively extends pipe of concrete service life 10-20 and reduces daily maintenance expense and water delivery cost.
Compared with prior art, the present invention have combine sealing effect is good, service life is long, favorable anti-corrosion effect, maintenance at
This low advantage can be obviously prolonged the pipe of concrete 10-20 service life.
