A kind of buried Gas Pipe of PE high-wearing features, including external tube layer, PE tube layer and ripple skeleton, the ripple skeleton is helically looped around on the outside of PE tube layer, the ripple skeleton both ends are equipped with interior ripple skeleton, the interior ripple skeleton is arranged between external tube layer and PE tube layer, interlayer is equipped between the adjacent interior ripple skeleton, wearing layer is equipped between the PE tube layer and ripple skeleton, cladding glass fibre wearing layer on the outside of the external tube layer and ripple skeleton, the interior ring-shaped distributed steel wire of cladding of the glass layer.The utility model is in entire loading process, stress suffered by PE tube layer is almost offset by relatively parallel interior ripple skeleton and ripple skeleton, so as to which stress is smaller, so that pipeline entire compression ability is strong, by setting PE tube layer, the leakproofness of pipeline is substantially increased, is not easily broken by being provided with ferroglass fibre abrasion layer pipeline on the outside, prolong the service life, and increase the flexibility of pipeline.
Description
Technical field
The utility model is related to pipe technology field, more particularly to a kind of buried Gas Pipe of PE high-wearing features.
Background technology
Corrugated pipe is using polyvinyl resin as primary raw material, adds in appropriate amount of addition agent, extruded molding, application is more and more wider
It is general, gradually apply to building, communication, agricultural.Have many advantages, such as that light-weight, resistance is small, compression strength is high, easy for construction,
It is the ideal material for replacing cast iron pipe and Cement Concrete pipe.Existing bellows integral strength is poor, is squeezed and easily generates rupture,
And it is easily worn after the permanent use of high spot by the external world, greatly reduces service life.Bellows is usually smooth
Inner wall layer and outer profile undulate outer wall layer, due to reasons in structure, the ring stiffness of this kind of bellows is relatively low, and critical external compressive resistance is born
Loading capability is relatively poor, and tubing easily deforms, and using effect is bad in particular circumstances.For this purpose, it is proposed that one
The kind buried Gas Pipe of PE high-wearing features.
Utility model content
The main purpose of the utility model is that providing a kind of buried Gas Pipe of PE high-wearing features, background can be effectively solved
The problems in technology.
To achieve the above object, the technical solution that the utility model is taken is：
A kind of buried Gas Pipe of PE high-wearing features, including external tube layer, PE tube layer and ripple skeleton, the ripple skeleton is in spiral shell
Rotation is looped around on the outside of PE tube layer, and the ripple skeleton both ends are equipped with interior ripple skeleton, and the interior ripple skeleton is arranged on outer tube
Between layer and PE tube layer, interlayer is equipped between the adjacent interior ripple skeleton, is set between the PE tube layer and ripple skeleton
There is wearing layer, glass fibre wearing layer is coated on the outside of the external tube layer and ripple skeleton, cladding is in ring in the glass layer
The steel wire of shape distribution.
Further, the ripple skeleton and interior ripple skeleton section are in arc-shaped.
Further, the interior ripple skeleton depth of section is equal to the half of ripple skeleton depth of section.
Further, filled layer is equipped between the ripple skeleton and PE tube layer.
Further, interior filled layer is equipped between the interior ripple skeleton and PE tube layer.
Further, the filled layer and interior filled layer are foam.
Further, the interior ripple skeleton and ripple skeleton junction section are in arc-shaped.
Compared with prior art, the utility model has the advantages that：In use, for prevent PE tube layer by
It crushes and splits, when ripple skeleton stress generates deformation, can stress be offset by the interior ripple skeleton of both sides, when external tube layer stress
When, interior ripple skeleton generates deformation, stress is offset to contract by ripple skeleton, by ripple skeleton and interior ripple skeleton
The filled layer of side and interior filled layer, not only buffer capacity is strong, but also cost is low for filled and process material, and entire loading process
In, the stress suffered by PE tube layer is almost offset by relatively parallel interior ripple skeleton and ripple skeleton, so as to which stress is smaller, is made
It is strong to obtain pipeline entire compression ability, by setting PE tube layer, the leakproofness of pipeline is substantially increased, by being provided on the outside
Ferroglass fibre abrasion layer causes pipeline to be not easily broken, and prolongs the service life, and increases the flexibility of pipeline.

Specific embodiment
To be easy to understand technical means, creative features, achievable purpose and effectiveness of the utility model, below
With reference to specific embodiment, the utility model is expanded on further.
As shown in Figs. 1-2, a kind of buried Gas Pipe of PE high-wearing features, including external tube layer 5, PE tube layer 7 and ripple skeleton 3,
The ripple skeleton 3 is helically looped around 7 outside of PE tube layer, and 3 both ends of ripple skeleton are equipped with interior ripple skeleton 1, described
Interior ripple skeleton 1 is arranged between external tube layer 5 and PE tube layer 7, and interlayer, the institute are equipped between the adjacent interior ripple skeleton 1
It states and wearing layer is equipped between PE tube layer and ripple skeleton, cladding glass fibre wearing layer on the outside of the external tube layer and ripple skeleton,
The ring-shaped distributed steel wire of cladding in the glass layer.
Wherein, the ripple skeleton 3 and interior 1 section of ripple skeleton are in arc-shaped.
Wherein, interior 1 depth of section of ripple skeleton is equal to the half of 3 depth of section of ripple skeleton.
Wherein, filled layer 4 is equipped between the ripple skeleton 3 and PE tube layer 7.
Wherein, interior filled layer 2 is equipped between the interior ripple skeleton 1 and PE tube layer 7.
Wherein, the filled layer 4 and interior filled layer 2 are foam.
Wherein, the interior ripple skeleton 1 and 3 junction section of ripple skeleton are in arc-shaped.
A kind of buried Gas Pipe of PE high-wearing features of the utility model, in use, to prevent PE tube layer 7 from being crushed
It splits, when 3 stress of ripple skeleton generates deformation, can stress be offset by the interior ripple skeleton 1 of both sides, when 5 stress of external tube layer,
Interior ripple skeleton 1 generates deformation, offsets stress to contract by ripple skeleton 3, passes through ripple skeleton 3 and interior ripple skeleton 1
The filled layer 4 of inside and interior filled layer 2, not only buffer capacity is strong, but also cost is low for filled and process material, and entire stress
