Abstract
Disclosed is a double plain wall water draining pipe. The double plain wall water draining pipe is formed by winding of a plastic steel strip and heat welding. The double plain wall water draining pipe is characterized in that a rectangular cavity is arranged in the strip. A circular steel pipe is embedded in the cavity so as to form a reinforcing rib. The inner side wall and the outer side wall of the strip are connected into a whole by the circular steel pipe. A supporting part is formed by the circular steel pipe. The circular steel pipe serves as the reinforcing rib of the water draining pipe, and therefore the double plain wall water draining pipe is high in ring stiffness. Meanwhile, the circular steel pipe is good in forming process, and therefore requirement of production is met.
Description
Technical field
The utility model relates to the drainage pipe that uses in a kind of municipal engineering, specifically a kind of two flat walls waste pipe.
Background technique
The applicant is a kind of steel plastic band material of application before, comprises the band body of extrusion moulding, is provided with the some cavitys that extend in the longitudinal direction in the band body interior, and is inlaid with steel band in the internal rib of band body; So not only utilize the antiseptic property of plastics but also utilized the rigidity of steel band, guaranteed buried pipe ring stiffness, owing to having hollow structure, reduced the consumption of plastics simultaneously, increased substantially the cost performance of tubing.The two flat walls waste pipe that the plastic-steel band winding-shaped of this structure becomes so have higher intensity, is vertical existence owing to steel band owing to setting is steel band still, so also there is the easy phenomenon of muscle.
The model utility content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of two flat walls waste pipe, by improving the structural type of web frame, improves the rigidity of waste pipe.
The technical scheme in the invention for solving the technical problem is: a kind of two flat walls waste pipe, twining also by the plastic-steel band, thermal weld forms, it is characterized in that, described band inside has rectangular enclosure, and in described cavity, embed round steel pipe to form stiffening rib, described round steel pipe is connected the interior outer side wall of band, and described round steel pipe forms supporting element.
All there is the plastics resin layer in the interior outside at described round steel pipe.
The beneficial effects of the utility model are: the utility model uses round steel pipe as the stiffening rib of waste pipe, has higher ring stiffness, and round steel pipe has preferably moulding process simultaneously, can meet the needs of production.
Description of drawings
Fig. 1 is stereogram of the present utility model;
Fig. 2 is sectional view of the present utility model;
Fig. 3 is A place enlarged view among Fig. 2;
Among the figure: 1 band, 2 cavitys, 3 round steel pipes, 4 resin layers.
Embodiment
Such as Fig. 1～shown in Figure 3, a kind of two flat walls waste pipe is twined and welding forms by the plastic-steel band, is the two flat walls waste pipe that is all the plane inside and outside a kind of.
Improvement is the improvement of belt structure form, band is molding and forming, band 1 inside has the cavity 2 of rectangle, around band 1, has certain wall thickness, both made things convenient for spiral welded, also make things convenient for moulding, in cavity 2, embed round steel pipe 3 is arranged, round steel pipe is connected the interior outer side wall of band, on one side operation is extruded in round steel pipe 3 extrusion-deformations on one side, forms continuous stiffening rib, PE material resin layer 4 is all arranged in the interior outside of round steel pipe, this structure can once-through in the process of extruding and moulding, and round steel pipe forms supporting element, can improve the ring stiffness of waste pipe.
With respect to steel band, the stiffening rib that round steel pipe is made has better rigidity and lighter and handier quality, can improve the performance of waste pipe.
Except the described technical characteristics of specification, be the known technology of those skilled in the art.
Claims (2)
1. two flat walls waste pipe, formed by the winding of plastic-steel band and thermal weld, it is characterized in that, described band inside has rectangular enclosure, and embed round steel pipe to form stiffening rib in described cavity, described round steel pipe is connected the interior outer side wall of band.
2. a kind of two flat walls waste pipe according to claim 1 is characterized in that, in the interior outside of described round steel pipe the plastics resin layer is arranged all.
