Abstract
The utility model relates to a pipeline, in particular to a hollow wall plastic steel winding pipe. The hollow wall plastic steel winding pipe is formed by a plurality of ring high-density polyethylene plastic steel plate strips in a splicing mode through linear low-density polyethylene base gel. Each high-density polyethylene plastic steel plate strip is mainly composed of an outer wall and an inner wall, a ring reinforcing rib is formed between the outer wall and the inner wall, a region clamped between the outer wall and the inner wall is divided into a plurality of closed ring cavities by the reinforcing rib, front and back splicing faces of each high-density polyethylene plastic steel plate strip are of a ring shape, and the linear low-density polyethylene base gel is filled between ring splicing faces of adjacent high-density polyethylene plastic steel plate strips. A ring steel strip is arranged in the reinforcing rib, and an axis of each steel strip and an axis of each ring high-density polyethylene plastic steel plate strip coincide. The hollow wall plastic steel winding pipe is simple in manufacturing, low in cost, easy to manipulate and high in rate of finished products, and simplifies a plate strip winding pipe-manufacturing process. Steel strips and the plate strips are vertically distributed, ring stiffness is greatly improved, and stress distribution is balanced, so that a product is strong in bearing capability, stable and durable.
Description
Technical field
The utility model relates to a kind of pipeline, especially the hollow wall plastic-steel spirally-wound pipe.
Background technique
Existing more typical two kinds of products are:
1. steel band pre-shaping two flat walls entwining tube, its production method are to add pre-formed steel band after producing the hollow sheeting band earlier, and two-sided to add glue Wrapping formed.This pipe, strip are produced reject rate height in early stage, easy-formation not, and the pre-shaping steel band adjusts that difficulty is big, waste product is many, and when Wrapping formed, pitch is not subjected to the steel band restriction easy to operate and easily strutted by steel band, because steel band is fixing in pipe, so that pipe shrinks is big, yielding.Steel band is waveform, limited by shape, and steel using amount is big, has increased cost of production.
2. plastic-steel spirally-wound pipe, its production method are to add primer, Wrapping formed single wall plastic steel pipe after the plastic-steel strip of first production mountain font.The moulding process of this pipe is outer typing moulding, and the primer bonding lacks pressure, and adhesive surface is little, and is easy to crack.Longitudinal plane is arranged for the mountain font, does not have outer wall, causes tube wall thin, the seepage of easily boring a hole.Because its outside entire body is the spiral shell rib, transportation, installation difficulty are big, and easy to hang bumping, and cause that steel band is exposed to get rusty.Because be single wall, landform changes slightly, and pipeline is easy to crack, and engineering risk is big.
In addition, when making existing entwining tube because its character determines its preparation process to exist following defective: 1. because being subjected to the restriction of strip speed of production, thereby can only carry out strip in advance as laying in the increase with cost of taking that has caused storehouse; 2. also need prefabricated winding steel when strip is twined, the poor controllability of the pre-formed and winding of steel band easily causes producing waste product in the tubulation process, has increased cost of production.
Summary of the invention
The utility model is intended to address the above problem, the hollow wall plastic-steel spirally-wound pipe is provided, it has overcome traditional steel band pre-shaping two flat walls entwining tube reject rate height, easy-formation not, and the pre-shaping steel band adjusts that difficulty is big, waste product is many, and pipe shrinks big, yielding, cost of production reaches the plastic-steel spirally-wound pipe transportation greatly, installation difficulty is big, and easy to hang bumping causes that steel band is exposed to get rusty, and pipeline is easy to crack, drawbacks such as engineering risk is big, its technological scheme that adopts is as follows:
The hollow wall plastic-steel spirally-wound pipe, be spliced by the linear low density polyethylene (LLDPE) primer by several annular high density polyethylene (HDPE) plastic-steel strips, described high density polyethylene (HDPE) plastic-steel strip mainly is made up of outer wall and inwall, be formed with ring stiffener between described outer wall and the inwall, described stiffening rib becomes folded region separation between outer wall and the inwall toroidal cavity of several sealings, the front and back splicing surface of high density polyethylene (HDPE) plastic-steel strip is annular, and the linear low density polyethylene (LLDPE) primer is filled between the annular splicing surface of adjacent high density polyethylene (HDPE) plastic-steel strip.
On the technique scheme basis, be provided with ring steel belt in the described stiffening rib, the axis of the axis of described steel band and annular high density polyethylene (HDPE) plastic-steel strip coincides.
The utlity model has following advantage: 1. strip making simpler production cost is low, with Wrapping formed on-line synchronous production, has reduced the parking space of strip, has saved carrying cost; 2. strip is twined the simplification of tubulation operation, easily controls the yield rate height; 3. steel band and strip vertical distribution improve ring stiffness greatly, and stressed distributing equilibrium, thereby make the goods bearing capacity strong, stable lasting.

1. high density polyethylene (HDPE) plastic-steel strip, 2. outer wall, 3. inwall, 4. stiffening rib, 5. steel band, 6. linear low density polyethylene (LLDPE) primer.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and example:
As depicted in figs. 1 and 2, the hollow wall plastic-steel spirally-wound pipe of present embodiment, be spliced by linear low density polyethylene (LLDPE) primer 6 by several annular high density polyethylene (HDPE) plastic-steel strips 1, described high density polyethylene (HDPE) plastic-steel strip 1 mainly is made up of outer wall 2 and inwall 3, be formed with ring stiffener 4 between described outer wall 2 and the inwall 3, described stiffening rib 4 becomes folded region separation between outer wall 2 and the inwall 3 toroidal cavity of several sealings, the front and back splicing surface of high density polyethylene (HDPE) plastic-steel strip 1 is annular, linear low density polyethylene (LLDPE) primer 6 is filled between the annular splicing surface of adjacent high density polyethylene (HDPE) plastic-steel strip 1, after being about to annular high density polyethylene (HDPE) plastic-steel strip 1 longitudinally cutting, linear low density polyethylene (LLDPE) primer 6 type linearly on this longitudinally cutting face.
Preferably, be provided with ring steel belt 5 in the described stiffening rib 4, the axis of the axis of described steel band 5 and annular high density polyethylene (HDPE) plastic-steel strip 1 coincides.
