Abstract
The utility model provides a ring rigidity HDPE (High -Density polyethylene) double -wall corrugated pipe great relatively, including be straight tube -shape inner wall layer and with the outer wall layer that the inner wall layer melting is connected, the longitudinal section's of outer wall layer outline is the wave, be provided with a plurality of longitudinal arrangement's rib on the outer wall layer on the longitudinal section of outer wall layer, the height of rib does the third of the wave crest height of outer wall layer. Through setting up the rib on the wall layer outside for can interconnect between corrugated each crest of outer wall layer longitudinal section together, effectively improved the ring rigidity of HDPE bellows, also can improve the shock resistance of HDPE bellows simultaneously, simultaneously, with the rib highly set up the third into the wave crest height of outer wall layer, effectively avoid the influence of the external wall layer performance of rib.
Description
Technical field
This utility model relates to a kind of tubing, especially a kind of HDPE double-wall corrugated pipe.
Background technology
HDPE double-wall corrugated pipe, is called for short PE corrugated tube, is that a kind of one made for raw material with high density polyethylene (HDPE) is novel
Lightweight tubing, has that lightweight, high pressure resistant, good toughness, construction be fast and the feature such as life-span length, be mainly used in municipal sewage and
Draining back in closed tube net, and the pipe network such as agricultural, chemical industry, underground communication pipeline of rainwater.As an alternative conventional concrete pipe and
A kind of novel tube of cast iron pipe, HDPE double-wall corrugated pipe has been widely used.
Existing HDPE double-wall corrugated pipe generally includes smooth inner wall layer and the outer wall layer of outline undulate, due to
Reasons in structure, the ring stiffness of this kind of HDPE double-wall corrugated pipe is on the low side, and critical external compressive resistance load capacity is relatively poor, and tubing is it may happen that become
Shape or lateral deflection unstable failure occurs.
In view of this, the structure of HDPE double-wall corrugated pipe is conducted in-depth research by the applicant, then has this case to produce.
Utility model content
The purpose of this utility model is the HDPE double-wall corrugated pipe providing a kind of ring stiffness relatively large.
To achieve these goals, this utility model adopts the following technical scheme that
A kind of HDPE double-wall corrugated pipe, melts, including the inner wall layer in straight-tube shape with described inner wall layer, the outer wall being connected
Layer, the outline undulate of the longitudinal cross-section of described outer wall layer, described outer wall layer is provided with multiple rib being longitudinally arranged,
On the longitudinal cross-section of described outer wall layer, the height of described rib be the waveform crest height of described outer wall layer three/
One.
As a kind of improvement of the present utility model, described rib has more than four, and each described rib is with described outer wall layer
Centered by axis, even cloth is on described outer wall layer.
As a kind of improvement of the present utility model, the cross section of described rib is inverted " u " font, and the wall thickness of described rib
Identical with the wall thickness of described outer wall layer.
As a kind of improvement of the present utility model, the inner space of described rib and the inner space of described outer wall layer are mutual
Connection.
Using technique scheme, this utility model has the advantages that
By arranging rib on outer wall layer so that can phase between each crest corrugated of outer wall layer longitudinal cross-section
Connect together, be effectively increased the ring stiffness of HDPE corrugated tube, also can improve the shock resistance of HDPE corrugated tube simultaneously；
Meanwhile, the height of rib is set to outer wall layer waveform crest height 1/3rd, be prevented effectively from rib to outer wall layer
The impact of performance.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model HDPE double-wall corrugated pipe；
Fig. 2 is the longitudinal cross-section schematic diagram of this utility model HDPE double-wall corrugated pipe；
Fig. 3 is the partial enlarged drawing of position at A in Fig. 2.
Each figure indicates corresponding as follows:
10-outer wall layer；11-bulge loop；
12-scrobicular ring；13-rib；
20-inner wall layer.
Detailed description of the invention
With specific embodiment, this utility model is described further below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, the HDPE double-wall corrugated pipe that the present embodiment provides, including inner wall layer 20 He in straight-tube shape
The outer wall layer 10 that be connected melted with inner wall layer 20, inner wall layer 20 is identical with the inner wall layer structure of conventional HDPE double-wall corrugated pipe,
The most no longer describe in detail.
The outline undulate of the longitudinal cross-section of outer wall layer 10, this corrugated crest is on outer wall layer 10 formation
Bulge loop 11, this corrugated trough is on outer wall layer 10 scrobicular ring 12 formed, and bulge loop 11 and scrobicular ring 12 alternate layout, this
Structure is identical with outer wall layer 10 structure of conventional HDPE double-wall corrugated pipe, on the basis of this structure, and the outer wall of the present embodiment
Being provided with multiple rib 13 being longitudinally arranged on layer 10, rib 13 is connected on the outer surface of scrobicular ring 12 and runs through each bulge loop
11, i.e. the length direction of rib 13 is perpendicular with bulge loop 11.Adjacent two bulge loops 11 can be linked together by rib 13, have
The ring stiffness that improve HDPE double-wall corrugated pipe of effect.
On the longitudinal cross-section of outer wall layer 10, the height of rib 13 be the waveform crest height of outer wall layer 10 three/
One.It should be noted that the height of crest refers to the vertical dimension between corrugated trough and crest, i.e. shown in Fig. 3 herein
X segment distance, the height of rib 13 refer to corrugated trough and rib 13 away from the maximum between the side of trough side hang down
Straight distance, i.e. Y segment distance shown in Fig. 3.
Preferably, in the present embodiment, rib 13 has more than four, and each rib 13 is even centered by the axis of outer wall layer 10
Cloth is on outer wall layer 10.So may insure that the uniform force of each radial position of HDPE double-wall corrugated pipe.
Preferably, in the present embodiment, the cross section of rib 13 is inverted " u " font, and the wall thickness of rib 13 and outer wall layer
The wall thickness of 10 is identical.Additionally, the inner space of the inner space of the inverted " u " font of rib 13 and outer wall layer 10 is interconnected, this
Sample is easy to the molding of the HDPE double-wall corrugated pipe of the present embodiment.
Above in conjunction with accompanying drawing, this utility model is described in detail, but embodiment of the present utility model not only
Being limited to above-mentioned embodiment, this utility model can be made various deformation according to prior art by those skilled in the art, as incited somebody to action
Rib 13 in above-described embodiment by more than four be changed to one or two etc., these broadly fall into protection model of the present utility model
Enclose.
