Abstract
The utility model belongs to the field of drainage technology and especially relates to a drain pipe. The technical scheme of the drain pipe is that: the drain pipe comprises a flat wall pipe and winding pipes disposed outside the flat wall pipe; the flat wall pipe is formed by winding and welding of a PE profiled bar equipped with steel bands so that the flat wall pipe is enabled to be tight and be free from leakage; at least two empty cavities are arranged on the cross section of the PE profiled bar; a longitudinal partition is arranged between two empty cavities; a steel band is arranged in the interior of each longitudinal partition; and the winding pipes are composite pipes which are formed in such a way that PE pipes are coated with lining PP corrugated pipes so that strength of pipelines is greatly improved and service lifetime of the pipelines is prolonged. The drain pipe is advantaged by convenient and rapid in connection and construction of the pipelines, convenient in hoisting transportation, low in requirement for treatment of a foundation and low in construction cost of the pipelines.
Description
Technical field
The utility model belongs to plumbing technical field, relates in particular to a kind of waste pipe.
Background technique
Bigbore supplying drainage of the prior art is generally to adopt the steel that steel are combined with plastics to mould entwining tube, steel are added in the cavity of plastics, although this structure can increase the intensity of pipeline, can be in long-term using process, due to the extraneous factors such as pressure, and cause the steel in pipeline to be shifted, thereby the compression resistance of planting pipeline declines greatly, the steel of displacement also may destroy pipeline simultaneously, because pipeline is rolled and formed by heat-melting butt-joint spiral by banded sheet material, the compression resistance of joint a little less than, and the intensity of the pipeline reducing.
Summary of the invention
The purpose of this utility model is, overcomes the deficiencies in the prior art, and a kind of waste pipe is provided, this technological scheme is simple in structure, and speed of production and quality are controlled well, the corrosion of control liner steel band, the intensity of pipeline is improved greatly, also extended the working life of pipeline simultaneously.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of waste pipe, comprise walled tube and the entwining tube that is positioned at walled tube outside, and described walled tube is wound around and is welded by the PE profile shapes that contains steel band, closely and not leaks; On the cross section of PE profile shapes, there are at least two cavitys, between two cavitys, have mediastinum, in the inside of described mediastinum, have steel band, described entwining tube is that liner is the coated PE pipe in PP bellows, outside, play the ring stiffness that strengthens pipeline, improved the anti-pressure ability of pipeline.
Described planomural pipeline outside is to have PE plastic material to be entwined, and the flexibility of pipeline is fine, and shock resistance is good.
On the cross section of described PE profile shapes, there are three cavitys.Between three cavitys, have two mediastinums, there is steel band each mediastinum inside.
The beneficial effects of the utility model are: a kind of waste pipe, comprise walled tube and the entwining tube that is positioned at walled tube outside, and described walled tube is wound around and is welded by the PE profile shapes that contains steel band, closely and not leaks; On the cross section of PE profile shapes, there are at least two cavitys, between two cavitys, there is mediastinum, there is steel band inside in described mediastinum, described entwining tube is that liner is the coated PE pipe in PP bellows, outside, due to the walled tube of this structure and the combination of entwining tube, greatly improve the intensity of pipeline, extended the working life of pipeline.The connection construction of pipeline is convenient and swift, and hoisting transportation is convenient, and requiring that ground is processed is relatively low, and this type of pipeline construction expense is lower.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
In figure: 1-entwining tube, 2-walled tube, 3-cavity, 4-steel band, 5-mediastinum, 6-PE profile shapes.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Embodiment
A kind of waste pipe, comprise walled tube and the entwining tube 1 that is positioned at walled tube 2 outsides, described walled tube 2 is wound around and is welded by the PE profile shapes 5 that contains steel band 4, on the cross section of PE profile shapes 6, there are three cavitys 3, between two cavitys 3, there is mediastinum 5, in the inside of described mediastinum 5, have steel band 4, described entwining tube 1 for liner be the coated PE pipe of PP bellows, outside.
Claims (2)
1. a waste pipe, comprise walled tube and the entwining tube that is positioned at walled tube outside, it is characterized in that: described walled tube is wound around and is welded by the PE profile shapes that contains steel band, on the cross section of PE profile shapes, there are at least two cavitys, between two cavitys, there is mediastinum, there is steel band inside in described mediastinum, and described entwining tube is that liner is the coated PE pipe in PP bellows, outside.
2. waste pipe according to claim 1, is characterized in that: on the cross section of described PE profile shapes, have three cavitys.
