Abstract
The utility model relates to PVC profile spiral winding technique, i.e. a kind of large diameter wound pipe, comprises the body 2 that at least two block-type material 1 spiral windings are formed as one; Be provided with ring stiffness between described adjacent two block-type materials 1 and strengthen pier 3.Due to described structure and method, reduce cost of production and improve ring stiffness.
Description
Technical field
The utility model relates to PVC profile spiral winding technique, especially a kind of large diameter wound pipe and winding method thereof improving ring stiffness and reduce cost of production.
Background technique
All bigbore pipeline can be used in a large number in fields such as blowdown, diversion, agricultural irrigation, building block, traffic, communications.The pipeline of prior art is nothing more than having concrete pipe, metallic conduit and PVC plastic pipeline, and this few class pipeline all needs large mold and supporting big scale production equipment aborning, and pipe production cost is remained high.
02276483.6 multifunction spiral pipe winding machine announced that the Chinese patent of the utility model people model utility is announced solves the problems referred to above, it can construction and installation place pass through direct for PVC profile spiral winding to become required bigbore PVC spiral winding pipe again, not only can reduce cost of production, pipeline can also be made to have the function of antiacid alkali.But prior art is that just PVC profile overlapped rear [or PVC profile is mutual bonding rear by glue] direct Stetch Wrapping Machine spiral winding of sending into makes pipeline, and the large diameter wound pipe ring stiffness that the method is produced only has 3-4 KN/m
2, be produced into book high.
In sum, the spiral winding pipe ring stiffness that the PVC profile spiral winding technique of prior art is produced only has 3-4 KN/m
2, and need 3 to 5 layers, or more than 5 layers, cost of production is high.
Model utility content
The purpose of this utility model is to provide a kind of large diameter wound pipe improving ring stiffness and reduce cost of production.
The technological scheme adopted for realizing the utility model above-mentioned purpose is: a kind of large diameter wound pipe, comprises the body that at least two block-type material spiral windings are formed as one; Wherein:
Be provided with ring stiffness between described adjacent two block-type materials and strengthen pier.
Due to said structure, the ring stiffness of setting strengthen pier role similar with bridge pier [is wound around and strengthens pier by ring stiffness between front section bar and mutually support, ring stiffness enhancing pier role and bridge pier similar; After entering screw conveyer winding, the mutual wedging of pier is strengthened by ring stiffness between section bar, each stratotype material is made mutually to be wound around tightr], effectively can improve ring stiffness, large diameter wound pipe that pier compound rear screw is wound in can reach 8-12 KN/m after testing to adopt two-layer section bar and ring stiffness to strengthen
2, while improve ring stiffness and reduce cost of production.
Accompanying drawing explanation
The nonlimiting examples that the utility model can be provided by accompanying drawing further illustrates.
Fig. 1 is the structural representation of the utility model large diameter wound pipe.
Fig. 2 is the structural representation of the utility model section bar width direction
In figure: 1,101 and 102 be section bar; 2, body; 3, ring stiffness strengthens pier; 4, slab body to be wound; 5, tool joint pin; 6, female joint; 7, hollow part.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
See the large diameter wound pipe in accompanying drawing 1 to 2, figure, comprise the body 2 that at least two block-type material 1 spiral windings are formed as one; Wherein:
Be provided with ring stiffness between described adjacent two block-type materials 1 and strengthen pier 3.
In above-described embodiment, preferably: the sectional shape that described ring stiffness strengthens pier 3 is polygonal or circle.
For ensureing that entwining tube is mutually closely wound around between each section bar 1 in winding process, in above-described embodiment, preferably: between adjacent ring rigidity enhancing pier 3, there is gap.
For ensureing that entwining tube is convenient to metal detector in using process and is detected, easy access personnel overhaul, in above-described embodiment, preferably: be embedded with the metal chip detected for detector in described ring stiffness enhancing pier 3 or be fixed with the metal chip for detector detection on ring stiffness enhancing pier 3 surface, between each metal chip, mutually forming checking network.In follow-up maintenance process, if that local appearance of entwining tube leaks or depression, metal detector just can detect intuitively, makes repair personnel find source of leaks accurately fast, realizes rapid rush-repair.
For ensureing that section bar 1 edge in winding can closely be wound around, in above-described embodiment, preferably: the two side on the length direction of described section bar 1 is respectively arranged with tool joint pin 5 and the female joint 6 of coupling mutually.
For reducing energy consumption further, in above-described embodiment, preferably: through by hollow part 7 between the two side on the width direction of described section bar 1.
Obviously, all embodiments of foregoing description are a part of embodiments of the present utility model, instead of whole embodiments.Based on embodiment of the present utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the category of the utility model protection.
In sum, the utility model reduces cost of production and improves ring stiffness.
