Abstract
The utility model provides a hollow wall winding pipeline, which comprises a spiral winding extrusion hollow pipe and a pipeline wall that is formed by adhering with the melted plastic of the adjacent hollow pipe and is characterized in that: the pipe wall of extrusion hollow pipe is at least a double layer structure. The external thickness of the extrusion hollow pipe wall accounts for 10 percent to 30 percent of the total thickness. The extrusion hollow pipe is a square pipe and the outer edge angle of the pipe wall is a circular shape. The utility model has a reasonable structure and can reduce the using amount of DPE raw materials and cost, increase the rigidity of pipes and guarantee the melted plastic and extrusion hollow pipe firmly adhered.
Description
Technical field
The utility model relates to the building pipe field of urban construction, is a kind of hollow wall winding pipeline based on plastic raw material specifically.
Background technique
Existing hollow wall winding pipeline is to extrude hollow square tube spiral on the Wrapping formed machine of heavy caliber with extruder to twine, and fills between adjacent hollow tube simultaneously that melten gel is bonding to process.Because of its hollow tube tube wall is single layer structure (as shown in Figure 1), have following shortcoming: 1, consumption HDPE raw material is many, cost is high; 2, ring stiffness is low, and difficult quality is up to standard; If 3 reduce cost, the hollow tube raw material is through filling-modified melten gel and the bonding not firm phenomenon of hollow tube of then occurring, and there is serious hidden danger in quality of product.
Summary of the invention
The purpose of this utility model is to provide a kind of novel hollow wall winding pipeline at the deficiencies in the prior art, and it is rational in infrastructure, can reduce HDPE raw material consumption, reduces cost, and improves rigidity, guarantees melten gel and extrudes the bonding fastness of hollow tube.
The technical solution of the utility model is: a kind of hollow wall winding pipeline, comprise the tube wall that the melten gel of extruding hollow tube and bonding adjacent hollow tube that spiral twines forms, and it is characterized in that the described hollow tube tube wall of extruding is at least double layer construction.
The described outer layer thickness of extruding the hollow tube tube wall accounts for 10%~30% of total thickness.
The described hollow tube of extruding is a square tube, and the outer corner angle of tube wall are circular arc.
The utility model compared with prior art has many advantages and good effect:
1, to extrude hollow tube be double layer construction to the utility model, skin thin (account for total thickness 10%~30%), materials are less, availability performance, the higher polyethylene HDPE raw material of quality are made, and both can reduce cost, and can guarantee the bonding fastness of melten gel and hollow tube again.Internal layer thicker (account for total thickness 70%~90%), materials are more, and the HDPE raw material of available low price is filling-modified or filling-modified with reclaimed materials, and in fact filling-modified internal layer hollow tube plays the effect of " Steel Skeleton ", the product ring stiffness is increased substantially, reduce cost simultaneously.
2, the internal and external layer hollow tube can be from compound the extruding of same die head high temperature, and processing technology is simple, and adhesive integrity can be good, and cost of material is lower, is convenient to promote the use of.
Description of drawings
Fig. 1 extrudes the hollow wall winding pipeline part sectioned view that hollow tube is made for the prior art single layer structure;
Fig. 2 extrudes the hollow wall winding pipeline part sectioned view that hollow tube is made for the utility model double layer construction.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Referring to Fig. 2, a kind of hollow wall winding pipeline comprises the tube wall that the melten gel of extruding hollow tube and bonding adjacent hollow tube 1 that spiral twines forms.The described hollow tube of extruding is a square tube, and the outer corner angle of hollow square tube tube wall are circular arc.The hollow square tube tube wall is a double layer construction, and outer wall 2 thickness account for 10%~30% of total thickness, makes with performance, the higher polyethylene HDPE raw material of quality.Inner layer tube wall 3 accounts for 70%~90% of total thickness, and the HDPE raw material of available low price is filling-modified or add filling-modified making with reclaimed materials.
The inside and outside layer pipe the 3, the 2nd of hollow square tube, from compound the extruding of same die head high temperature, and helically-wound shaped on the Wrapping formed machine of heavy caliber, the integral adhesive performance is good.
Certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model; the variation of making, remodeling, interpolation or replacement, as: strengthen pipe thickness or increase hollow square tube tube wall layer number (as: can three layers of compound extruding), all should belong to protection domain of the present utility model.
Claims (3)
1, a kind of hollow wall winding pipeline comprises the tube wall that the melten gel of extruding hollow tube and bonding adjacent hollow tube that spiral twines forms, and it is characterized in that the described hollow tube tube wall of extruding is at least double layer construction.
2,, it is characterized in that the described outer layer thickness of extruding the hollow tube tube wall accounts for 10%~30% of total thickness according to the described hollow wall winding pipeline of claim 1.
3, according to claim 1 or 2 described hollow wall winding pipelines, it is characterized in that the described hollow tube of extruding is a square tube, the outer corner angle of tube wall are circular arc.
