Description
Technical field
The utility model relates to a kind of HDPE double-wall corrugated pipes.
Background technique
High density polyethylene (HDPE) (HDPE) double-wall corrugated pipe is a kind of New pipe with cyclic structure outer wall and smooth internal walls
Material.By the development of more than ten years and perfect, via single Cultivar development to complete product line.At present in production technology
It is technically very mature with using.Due to the cost of its excellent performance and relatively economical, the developed countries such as America and Europe
Great promotion and application are obtained.
In China, the promotion and application of HDPE double-wall corrugated pipe, which are in, rises the situation stage, but existing double-walled wave
The ring stiffness of line pipe is insufficient to the resistance of soil load, and compressive property is bad, and the deflection degree of double-wall corrugated pipe is not strong, is easy
It is influenced by surface subsidence.
Therefore, it is necessary to a kind of novel HDPE double-wall corrugated pipe be provided, to overcome defect in the prior art.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of HDPE double-wall corrugated pipe, the HDPE double-wall corrugated pipes
Light weight, compressive resistance is strong and possesses certain deflection degree.
The technical solution of utility model is as follows:
A kind of HDPE double-wall corrugated pipe, including internal layer straight pipe and outer layer bellows are set in the straight pipe outer wall of internal layer
There is the groove of annular, is equipped with an elastomeric element in the groove, the outer layer bellows trough is matched with the groove, described
Outer layer bellows trough is connected to the elastomeric element, forms multiple skies between the outer layer bellows and the internal layer straight pipe
Chamber, the cavity is interior to be filled with elastomer, and the outer wall of the outer layer bellows is equipped with wearing layer, and the wearing layer is equipped with anti-
Corrosion layer.
Further, the elastomeric element includes the spring being arranged in the groove and to be set to the spring separate
The arc panel of the groove side, the arc panel are connected to the outer layer bellows trough.
Further, the straight inside pipe wall of the internal layer is equipped with toughening ceramic layer.
Further, the internal layer straight pipe and the outer layer bellows are high density polyethylene pipe.
The utility model has the advantages that
The HDPE double-wall corrugated pipe of the utility model, by accommodating outer layer ripple in the groove of internal layer straight pipe setting annular
The trough of pipe improves the compressive resistance of the HDPE double-wall corrugated pipe, while elastomeric element is arranged in groove, so that the HDPE is bis-
The deflection degree of wall bellows is higher.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of HDPE double-wall corrugated pipe.
Specific embodiment
The utility model is described in further details below with reference to the drawings and specific embodiments:
Embodiment 1: such as Fig. 1, a kind of HDPE double-wall corrugated pipe 100, including internal layer straight pipe 1 and outer layer bellows 2 are described
1 outer wall of internal layer straight pipe is equipped with the groove 111 of annular, is equipped with an elastomeric element 112, the outer layer wave in the groove 111
2 trough of line pipe is matched with the groove 111, and 2 trough of outer layer bellows is connected to the elastomeric element 112, pass through by
Trough, which is set to groove 111, can be improved the critical external compressive resistance ability of the HDPE double-wall corrugated pipe 100, enhance the ring stiffness of tubing,
To improve pipeline to the resistance of soil negative pressure.
A plurality of cavities 10 are formed between the outer layer bellows 2 and the internal layer straight pipe 1, are filled in the cavity 10
Elastomer 101 can be improved the buffer capacity of the outer layer bellows 2 by filling elastomer 101 in the cavity 10
Power, to further promote the anti-pressure ability of tubing.
The outer wall of the outer layer bellows 2 is equipped with wearing layer 21, and the wearing layer 21 is equipped with etch resistant layer 22.In described
Layer 1 inner wall of straight pipe is equipped with toughening ceramic layer 12, and the toughening ceramic layer 12 enables to the internal layer straight pipe 1
Inner wall is more smooth, the frictional force of tube wall when reducing threading.
The elastomeric element 112 includes the spring 1121 being set in the groove 111 and is set to the spring
1121 arc panels 1122 far from 111 side of groove, the arc panel 1122 are connected to 2 trough of outer layer bellows.
The elastomeric element 112 is used to improve the deflection degree of the HDPE double-wall corrugated pipe, is connected to by arc panel 1122 described outer
The trough of layer bellows 1, while cooperating with the spring 1121 so that the deflection degree of HDPE double-wall corrugated pipe is higher.
The HDPE double-wall corrugated pipe of the utility model, by accommodating outer layer ripple in the groove of internal layer straight pipe setting annular
The trough of pipe improves the compressive resistance of the HDPE double-wall corrugated pipe, while elastomeric element is arranged in groove, so that the HDPE is bis-
The deflection degree of wall bellows is higher.
Basic principles, main features, and advantages of the present invention has been shown and described above.Current row
