Field.
But in the prior art, after winding pipe is embedded to underground, vertical reinforcing rib will receive radial and axial pressure
Power, reinforcing rib is easy diagonal distortion under the effect of larger pressure, to cause bearing capacity insufficient, the ring for reducing winding pipe is rigid
Degree, seriously affects the product quality and service life of tubing.
Utility model content
For the problem that winding pipe bearing capacity existing in the prior art is weak, ring stiffness is not high, the utility model is provided
A kind of HDPE hollow wall stud formula winding pipe.
The technical solution of the utility model are as follows: a kind of HDPE hollow wall stud formula winding pipe, it is arranged side by side including two
Structure band is connected by melten gel between two structure bands, and covers buffering on the surface of two structure bands
Layer, the structure band set gradually the first cuboid, the second cuboid and third cuboid, the structure band from left to right
Three cuboids be hollow structure, be equipped with vertical ribs, first rectangle in the hollow structure of second cuboid
" Ω " metallic framework is equipped in the hollow structure of body, two bottom ends of " Ω " metallic framework are embedded into first cuboid
In side wall, the top of first cuboid is tightly attached on the top of " Ω " metallic framework, sets in " Ω " metallic framework
Have a circular metal skeleton, the circular metal skeleton be tangential on described " Ω " metallic framework both sides and first cuboid
Bottom edge, the interior metallic framework being arranged of the third cuboid hollow structure is identical with first cuboid, the buffering
Several oval buffer cavities are in axial direction equipped at intervals in layer.
Further, the vertical ribs is high density polyethylene (HDPE).
Further, it can weld and fix between described " Ω " metallic framework and the circular metal skeleton.
Further, the buffer layer with a thickness of 3mm to 4mm.
The utility model has the beneficial effect that
1. the utility model by the structure of improvement structure band, i.e., is arranged in the cuboid two sides for being equipped with vertical ribs
Cuboid containing metallic framework, so that the tubing bearing capacity enhancing after winding, ring stiffness improve, and metallic framework designed
At " Ω " metallic framework and circular metal skeleton mutually supported, it is fitted to each other to form stable supporting structure, thus further
Greatly increase the bearing capacity and ring stiffness of tubing.
2. buffer layer is arranged in the utility model, several oval cushion chambers of axially spaced setting in buffer layer, when outer
When boundary's pressure is applied on tubing, buffer layer first can sensed pressure, internal oval buffer cavity can deform, inhale
Pressure outside receiving, slows down damage of the ambient pressure to structure band, and then improve the bearing capacity and ring stiffness of tubing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
In figure: 1- structure band, the first cuboid of 2-, the second cuboid of 3-, 4- third cuboid, 5- " Ω " metal bone
Frame, 6- circular metal skeleton, the vertical ribs of 7-, 8- buffer layer, 9- ellipse buffer cavity, 10- melten gel.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
A kind of HDPE hollow wall stud formula winding pipe as shown in Figure 1:, including two structure bands 1 arranged side by side, two
It is connected between structure band 1 by melten gel 10, and covers buffer layer 8 on the surface of two structure bands 1, structure band 1 is from a left side
The first cuboid 2, the second cuboid 3 and third cuboid 4 are set gradually to the right, and three cuboids of structure band 1 are hollow
Structure, the hollow structure of the second cuboid 3 is interior to be equipped with vertical ribs 7, and " Ω " gold is equipped in the hollow structure of the first cuboid 2
Belong to skeleton 5, two bottom ends of " Ω " metallic framework 5 are embedded into the side wall of the first cuboid 2, and the top of " Ω " metallic framework 5 is tight
It is affixed on the top of the first cuboid 2, is equipped with circular metal skeleton 6 in " Ω " metallic framework 5, circular metal skeleton 6 is tangential on
The bottom edge on the both sides of " Ω " metallic framework 5 and the first cuboid 2, the metallic framework being arranged in 4 hollow structure of third cuboid with
First cuboid 2 is identical, by improving the structure of structure band 1, i.e., sets in the cuboid two sides for being equipped with vertical ribs 7
