Abstract
The utility model discloses a HDPE cavity wall plastic steel wound pipe, include by extruding the body that the unit winding formed, extrude the unit including the substrate, be equipped with two bosss on the substrate, two bosss all with substrate integrated into one piece, be equipped with metal framework between two bosss, metal framework is " omega " shape, and metal framework's top exceeds the peak of boss, be equipped with the tie coat between the outer terminal surface that adjacent two were extruded the boss of unit, the top of extruding unit and metal framework covers there is the PE layer. The utility model discloses an increase by two bosss on the substrate, then with establishing metal framework between the boss for it is higher through its ring rigidity of the body after the winding, and the bonding face of extruding between the unit sets up on the terminal surface of boss, thus the bond area increased, make its bulk strength of body after the winding bigger, extrude unit and metal framework in addition and coat and be stamped the PE layer, can improve the corrosion resistance of whole tubular product.
Description
Technical field
This utility model relates to a kind of underground piping technology, particularly winding pipe.
Background technology
In order to improve the ring stiffness of tubing, the tube wall of existing double-walled corrugated tubing can add metallic framework, use metal
Skeleton bears the pressure of outside.Such as Chinese patent application, Publication No.: CN 204201303 U " HDPE hollow wall is moulded
Steel winding pipe road ", although it solves the integral loop rigidity of tubing well, but, owing to the shaping strength of its tubing is the highest,
Because winding pipe is all formed by spiral winding by base material, the when of winding it is by the way of bonding, adjacent by two
Base material couple together, therefore, the area of connecting portion determines the shaping strength of tubing largely.And prior art
In, the bonding size all only having inboard wall of tube body of base material, it is difficult to provide the tubing of high intensity.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of bulk strength higher double-walled corrugated tubing.
This utility model solves the solution of its technical problem: HDPE hollow wall plastic-steel winding, including by extruding
The body that unit is entwined, described extrusion unit includes ground, and described ground is provided with two boss, said two boss
Laying respectively at the two ends, left and right of ground, two described boss are all one-body molded with ground, are provided with gold between said two boss
Belonging to skeleton, described metallic framework is in " Ω " shape, and the top of metallic framework exceeds the peak of described boss, and described adjacent two are squeezed
It is provided with tack coat between the outer face of the boss going out unit；Described extrusion unit is coated with PE layer with the top of metallic framework.
As the further improvement of technique scheme, described boss is rectangular, and described boss hollow is arranged, described boss
Cavity be also rectangle.
As the further improvement of technique scheme, the wall thickness of described boss is identical with the thickness of ground.
As the further improvement of technique scheme, the inner face of described boss is provided with draw-in groove, described metallic framework
Two ends abut with draw-in groove.
The beneficial effects of the utility model are: this utility model is by increasing by two boss on ground, then at boss
Between add metallic framework so that its ring stiffness of body after being wound around is higher, and the bonding plane extruded between unit is arranged on
On the end face of boss, thus increase bond area so that its bulk strength of the body after winding is bigger, also have extrusion unit with
And on metallic framework, it is coated with PE layer, the corrosion resistance of overall tubing can be improved.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in this utility model embodiment, required in embodiment being described below
Accompanying drawing to be used is briefly described.Obviously, described accompanying drawing is a part of embodiment of the present utility model rather than complete
Portion's embodiment, those skilled in the art is not on the premise of paying creative work, it is also possible to obtain it according to these accompanying drawings
His design and accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below with reference to embodiment and accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is carried out
Clearly and completely describe, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment is only
It is a part of embodiment of the present utility model rather than whole embodiment, based on embodiment of the present utility model, the skill of this area
Other embodiments that art personnel are obtained on the premise of not paying creative work, belong to the model of this utility model protection
Enclose.It addition, all connection/annexations being previously mentioned in literary composition, the most singly refer to that component directly connects, and refer to can be according to concrete real
Execute situation, couple auxiliary by adding or reducing, form more excellent draw bail.Each technology in the invention is special
Levy, can be with combination of interactions on the premise of the most conflicting conflict.
With reference to Fig. 1, HDPE hollow wall plastic-steel winding, including the body being entwined by extrusion unit 1, described extrusion list
Unit 1 includes ground 11, and described ground 11 is provided with two boss 12, and said two boss 12 lays respectively at the left and right of ground 11
Two ends, two described boss 12 are all one-body molded with ground 11, are provided with metallic framework 2 between said two boss 12, described
Metallic framework 2 is in " Ω " shape, and the top of metallic framework 2 exceeds the peak of described boss, described adjacent two extrusion unit 1
Tack coat 3 it is provided with between the outer face of boss 12；Described extrusion unit 1 is coated with PE layer 4 with the top of metallic framework 2.Body
After shaping, owing to being supported by two boss and a metallic framework in " Ω " shape, so that the ring stiffness of body
Obtain good guarantee.And, the bonding location of extrusion unit is arranged on the outer face of boss, is arranged on relative to traditional
Bonding location on ground, its bonding area is bigger, so the bulk strength of tubing is higher.
Being further used as preferred embodiment, described boss 12 is rectangular, and described boss 12 hollow is arranged, described boss
The cavity of 12 is also rectangle.The boss of rectangle is so that bonding plane as far as possible smooth.
Being further used as preferred embodiment, the wall thickness of described boss 12 is identical with the thickness of ground 11.Squeezing of uniform thickness
Go out unit and can ensure that its good stressing conditions, it is to avoid extrusion unit occurs stress to concentrate because wall thickness is different, thus broken
Bad extrusion unit.
Being further used as preferred embodiment, the inner face of described boss 12 is provided with draw-in groove, described metallic framework 2
Two ends abut with draw-in groove.By arranging draw-in groove, so that metallic framework is tightr with the connection of boss.
Above better embodiment of the present utility model is illustrated, but the invention is not limited to described
Embodiment, those of ordinary skill in the art also can make all equivalent changes on the premise of this utility model spirit
Type or replacement, modification or the replacement of these equivalents are all contained in the application claim limited range.
