Description
Technical field
Reinforcing rib winding pipe is produced the present invention relates to a kind of band and with the band.
Background technique
Existing HDPE reinforcing rib winding pipe is twined under hot melt state using high density polyethylene (HDPE) (HDPE) material as raw material
Around molding, using polypropylene (PP) single-wall corrugated pipe as support construction, after natural wind cooling, cold conditions demoulding is prepared.By
Long with service life in it, quality is reliable and stable, easy to connect, good leak tightness, the advantages such as at low cost, has been widely used in city
The buried draining of city's municipal administration, blow-off line, cable, cable jacket pipe-line system etc..
In recent years, China continues to increase the design requirement bore of buried pipeline, while with the increasing of bore, it is also desirable to
Bigger buried depth, this requires tubing to have higher ring stiffness and non-deformability, to prevent from going out in use
Phenomena such as existing unstability conquassation.Due to process and structure characteristic, needed when producing high ring rigidity heavy caliber HDPE reinforcing rib winding pipe
It is made into multilayered structure, production cost is not only greatly improved, meter Chong is also increased therewith, increases difficulty of construction.In practical life
It is almost impossible that production process medium caliber DN1200 or more will meet the even 16KN of ring stiffness 12.5.
Existing HDPE reinforcing rib winding pipe, ribbed pipe use curved surface ribbed pipe, when producing HDPE reinforcing rib winding pipe in it
Wall and ribbed pipe are to squeeze out simultaneously, and during the winding process, ribbed pipe is in high temperature fused state, it is necessary to the PP single wall ripple of built-in cold conditions
Pipe supports so that it does not shrink collapses, this structure and technique suffers from the drawback that one, when PP heat resistance is bad or aperture compared with
When big, molding ribbed pipe deformation is serious, causes ring stiffness that design requirement is not achieved.Two, since PP and HDPE cannot merge bonding,
PP single-wall corrugated pipe is practical to have only served the process acts for propping up ribbed pipe, hardly acts as to the formation of pipe ring stiffness
With actually this moiety by weight is to slattern.Three, since curved surface ribbed pipe and inner wall flat rubber belting contact area are small, when winding, can be made
Thinning destruction tubing integral strength is locally squeezed at flat rubber belting, serious Shi Huicong thinnest part cracking eventually leads to leak.
Summary of the invention
The purpose of the present invention is to provide for a kind of band and produces reinforcing rib winding pipe with the band, existing to solve
The problem of HDPE reinforcing rib winding pipe ring stiffness is low, and tube body is easily deformed, and closes water unqualified easy leakage.
Idea of the invention is that cancelling PP single-wall corrugated pipe as support tube, replaced with offline prefabricated non-curved ribbed pipe
The curved surface ribbed pipe of existing HDPE reinforcing rib winding pipe, during Wrapping formed, non-curved ribbed pipe is only and inner wall flat rubber belting is viscous
The one side of knot is in high temperature fused state, ensure that it is Wrapping formed during non-curved ribbed pipe and inner wall flat rubber belting can reliable bond
Collapsing will not be shunk again.Since inner wall flat rubber belting and non-curved ribbed pipe are face contacts, there is no by the ironed hidden danger for weakening intensity.By
It in non-curved ribbed pipe is made in independent equipment, is not limited by winding process, size can be made greatly, so that using single layer
Non-curved ribbed pipe can produce heavy caliber epipodium stiffness pipe and be possibly realized.Due to eliminating PP single-wall corrugated pipe when winding,
Tubing weight and processing cost also can significantly reduce.
The invention is realized in this way a kind of band, it is especially useful in production reinforcing rib winding pipe, the band are non-curved
Band.
One of scheme: a kind of band, it is especially useful in production reinforcing rib winding pipe, the non-curved band are hollow square band
Material.
The two of scheme: be equipped in the hollow square band with the integrally formed reinforcing rib of band, the reinforcing rib is at least
It is connected there are two end with rectangular band inner wall.
Specifically there is following form:
1) a kind of band, the cross section of reinforcing rib are to connect rectangular band or more both sides and perpendicular to bottom edge
" 1 " font.
2) a kind of band, the cross section of reinforcing rib are the diagonal slash of the rectangular band two of connection, make rectangular band
Cross section become two triangles.
3) a kind of band, the cross section of reinforcing rib are the rectangular four diagonal X-shapeds of band of connection, make square band
The cross section of material becomes four triangles.
4) a kind of band, the cross section of reinforcing rib are " ten " font for connecting rectangular four sides of band, are made rectangular
The cross section of band becomes sphere of movements for the elephants shape.
5) a kind of band, the cross section of reinforcing rib are " people " font.
6) a kind of band, the cross section of reinforcing rib are "eight" shape.
7) a kind of band, the cross section of reinforcing rib are " Y " font.
8) a kind of band, the cross section of reinforcing rib are " rice " font.
The present invention produces reinforcing rib winding pipe with above-mentioned non-curved band, includes the following steps:
1) non-curved band production: hollow non-curved band is produced in non-curved band production equipment or with reinforcing rib
Non-curved band, non-curved band is packaged coiled, stacking stores for future use；
2) Wrapping formed: the non-curved strip coil that step 1) produces being placed in production line Special back rotating cage, cage is turned round
By non-curved band be in beginning bending state under conditions of be delivered on Wound Dies, non-curved band conveying while pair
Its interior curved side is heated on one side, and when non-curved band reaches Wound Dies, this face surface layer just reaches molten condition；It squeezes
Machine is extruded into the flat rubber belting of winding inside pipe wall out, and the mold that trolley carries rotation vertically moves, and drives flat rubber belting and non-curved band
Material, which synchronizes, is wrapped in die surface, and non-curved band and flat rubber belting are thermally melted in together, and formation inner surface is smooth, outer wall is non-in the shape of a spiral
The pipe structure of curved surface reinforcing rib winding pipe.
The non-curved reinforcing rib winding pipe that mold of the present invention is produced, connector and pipe structure are integrally formed.
The present invention uses multipurpose joint technology, connection using same material spigot-and-socket electric smelting connection, the double cushion rubbers connection of socket joint and
Electric smelting adds cushion rubber to connect three kinds of connection types.
Beneficial effect of the invention is to replace existing curved surface ribbed pipe in non-curved ribbed pipe with outside on pipe structure, take
Disappear internal PP single-wall corrugated pipe support.Winding process becomes the hot winding in part from complete hot winding, is reducing tubing weight
In the case of ensure that the high ring rigidity requirement of tubing.Using multipurpose joint technology, connection using same material spigot-and-socket electric smelting connection,
The double cushion rubbers connections of socket joint and electric smelting add cushion rubber three kinds of connection types such as to connect, to adapt to the different mounting conditions in building site.
