Description
Technical field
This utility model relates to municipal pipeline, is specifically related to a kind of steel plastic compount carat pipe.
Background technology
Carat pipe is widely used in the buried draining of Municipal, blow-off line, is also used for cable, cable jacket tubing etc..Because it uses circumstance complication, therefore ring stiffness, the pull resistance of carat pipe is required the highest.In order to meet ring stiffness requirement in the middle of prior art, reducing raw material usage, mainly the approach of the elastic modelling quantity and increase tube wall rotary inertia of trying one's best in the case of certain doses by improving raw materials implements improvement simultaneously the most as far as possible.Owing to the elastic modelling quantity of steel is far longer than high density polyethylene (HDPE), but steel are easily corroded and flexible deficiency, so allowing steel be combined with high density polyethylene (HDPE), are more satisfactory approach.But steel plastic composite structure of the prior art is unreasonable, exist and be stuck in strip because of steel and make steel at the viscous seam of strip and easily contact the problem that generation is corroded with pipeline pumped (conveying) medium, and because of steel, the little elastic modelling quantity making steel is far from playing a role with the contact surface of high density polyethylene (HDPE), causes steel plastic composite structure that the ring stiffness of tubing is not risen great role.A kind of reinforced carat pipe as disclosed in the Chinese utility model patent of Publication No. CN203309383U, it is formed by winding unit spiral winding, filled by PUR between adjacent winding unit and close, it is characterized in that winding unit has PE and makes winding main body and office in the reinforcing strip and the reinforcing ring that are wound around main body two ends, steel band it is installed with in reinforcing strip, reinforcing ring is with opening, after winding unit spiral winding, the side of winding unit mutually overlaps, reinforcing strip is inserted in reinforcing ring, the inwall of reinforcing ring is withstood in the end of reinforcing strip, and PUR is filled by lap-joint.
Utility model content
Technical problem to be solved in the utility model is to provide that a kind of ring stiffness is high, steel loop be difficult to burn into good stability steel plastic compount carat pipe.
For solving above-mentioned technical problem, the technical solution of the utility model is as follows:
Steel plastic compount carat pipe, including cylindrical tubing matrix, described cylindrical tubing matrix is mainly made up of spiral winding melting adhered multiple recombiner units, and described recombiner unit includes main body and be located at body contours the hollow enhancing ring becoming spiral；Described hollow strengthens to connect on ring inwall the steel loop identical with hollow enhancing ring-shaped；The main body of adjacent recombiner unit is fixed by viscose glue.
In order to avoid the adhesive portion between recombiner unit divides because of longitudinal power being pressed onto on tubing, such scheme is preferred, the inside and outside wall in main body one end of recombiner unit all convexes to form semi-arched clinch, the inside and outside wall of the main body other end the most horizontal-extending formation adhesive portion of recombiner unit；The semi-arched clinch of recombiner unit is taken in the adhesive portion of adjacent recombiner unit and is fixed by viscose glue.
Such scheme is preferred, a length of 15-25mm of described semi-arched clinch.
In order to make the elastic modelling quantity of steel play maximum effect, such scheme is preferred, and it is circular that described hollow strengthens ring.
In order to make pipeline when by weight, pressure thereon can be gently excessively on the inside and outside wall of pipeline, it is to avoid being subject to crushing because of pipeline part stress, such scheme is preferred, and it is 10-60mm that described hollow strengthens the radius of ring.
Compared with prior art, this utility model has the advantage that
1, in steel loop is arranged at hollow enhancing ring, namely it is covered by completely in the hollow enhancing ring formed by polyethylene so that steel loop does not contacts with pipeline pumped (conveying) medium, it is to avoid be corroded, good stability.
2, the bonding location between adjacent recombiner unit is horizontal direction, and bond area is big, adhesive property is stable so that tubing is when by weight, and bonding location will not occur problem of Cracking, also improve the hot strength of bonding location, extend the service life of tubing.
3, this steel plastic compount carat pipe also has good integrity, produces the feature that bulk strength workable, tubing is big.

Fig. 2 is the structural representation that 2 recombiner units are bonding.
Figure is numbered: 1, cylindrical tubing matrix；2, recombiner unit；3, hollow strengthens ring；4, steel loop；5, semi-arched clinch；6, adhesive portion；7, viscose glue.
Detailed description of the invention
This utility model is a kind of steel plastic compount carat pipe, as it is shown in figure 1, it includes that cylindrical tubing matrix 1, described cylindrical tubing matrix 1 are mainly made up of spiral winding melting adhered multiple recombiner units 2.Described recombiner unit 2 includes main body and strengthens ring 3 with the hollow being located at body contours and becoming spiral, and described hollow strengthens compact siro spinning technology on ring 3 inwall to be had and strengthen the steel loop 4 that ring 3 shape is identical, described main body and hollow with hollow and strengthen ring 3 and be made up of high density polyethylene (HDPE).Hollow on each recombiner unit 2 strengthens ring 3 can be 1, it is also possible to for multiple, and the inwall of each hollow enhancing ring 3 connects steel loop 4, is 1 in the preferred embodiment.
The main body of adjacent recombiner unit 2 can be welded, PUR is bonding, and in the preferred embodiment, the main body of adjacent recombiner unit 2 is fixed by viscose glue 7.In order to make connected recombiner unit 2 bonding more firm, the inside and outside wall in main body one end of recombiner unit 2 all convexes to form semi-arched clinch 5, the inside and outside wall of the main body other end the most horizontal-extending formation adhesive portion 6 of recombiner unit 2, the semi-arched clinch 5 of recombiner unit 2 matches with the adhesive portion 6 of adjacent recombiner unit 2, i.e. the semi-arched clinch 5 of recombiner unit 2 is taken in the adhesive portion 6 of adjacent recombiner unit 2 and fixed by viscose glue 7.There is the problem that hot strength is low in the bonding location being solved vertical direction by the bonding location of horizontal direction, namely more difficult because of pressurized cracking, extends the service life of pipeline.The a length of 15-25mm of described semi-arched clinch 5, namely the bonding length of adjacent recombiner unit 2, such bonding location and bonding length are the most easy to crack when pressurized and stretching.
It is circular that described hollow strengthens ring 3, makes the elastic modelling quantity of steel play maximum effect, can with pipeline pressurized time, what pressure can be mild is excessive on the inside and outside wall of pipeline, the anti-pressure ability of raising pipeline.
It is 10-60mm that described hollow strengthens the radius of ring 3, and releive best, comprcssive strength and ring stiffness of the pressure of tubing is maximum.
Certainly; the most simply combine accompanying drawing this utility model preferred embodiment is described in detail; not limit practical range of the present utility model, all equivalence changes made according to principle of the present utility model, structure and structure with this, all should be covered by protection domain of the present utility model.
