Abstract
Provided is a compound drain pipe which is a pipeline in a novel structure. The compound drain pipe is composed of an extrusion pipe of an inner layer and a winding pipe of an outer layer. The extrusion pipe is an integral extrusion molding polyethylene (PE) tubular product. The winding pipe is a double-flat-wall pipe which is smooth both inside and outside the double-flat-wall pipe. The double-flat-wall pipe is formed by strip materials and a compound layer. The strip matierals spirals, twines and is connected with the compound layer. The compound layer is formed on the outer surface of the extrusion pipe. Due to the fact that the compound pipeline is formed by twining a layer of the strip materials on the outer wall of the extrusion pipe, and the extrusion pipe is used as a base body for twining, compared with the prior art, the compound drain pipe is more easily molded and reduces production cost. Meanwhile, the stiffness and roundness are better after the twining of the strip materials, and the compound drain pipe is more suitable for manufacturing large diameter (more than 1 meter) drain pipes.
Description
Technical field
The utility model relates to the waste pipe technical field, specifically a kind of composite, water-drain pipeline.
Background technique
The main feature of polyvinyl plastics tubing be lightweight (its unit weight only for steel pipe 1/8), easy construction; Tube wall is highly polished, and fluid resistance is little, and is less scaling; Corrosion-resistant, the characteristics such as long service life are that country widelyd popularize a kind of product of application in recent years.But because the characteristics of polyvinyl piping materials self, the polyvinyl piping materials rigidity is lower, reaching usage requirement must increase by the method that increases wall thickness the ring stiffness of tubing, and the large increase of materials of Here it is tubing is especially in larger caliber (on the tubing of DN＞=200mm).So be the means of commonly using by the compound physical performance indexs such as ring stiffness that improve tubing, present design means normally adopts the mode that increases the steel rib to improve.
The model utility content
The purpose of this utility model is to provide a kind of composite drainage pipe, improves for the shortcoming of existing composite drainage pipe, solves the lower problem of heavy caliber drain pipe ring stiffness.
The technical scheme in the invention for solving the technical problem is: a kind of composite drainage pipe, it is characterized in that, the multiple tube that is formed by extruding pipe and the outer field entwining tube of internal layer, described extruding pipe is the PE tubing of integral extrusion moulding, described entwining tube is to twine and overlap hot weld by band to form at the outer surface of extruding pipe, is all smooth plain-wall pipe of inner and outer surface.
Be evenly equipped with some cavitys in the cross section of described band, and be provided with the steel band stiffening rib in the band matrix of described cavity both sides, further outline rigidity reduces materials.
The wall thickness of described extruding pipe is between 3 to 10mm.
The diameter of described composite drainage pipe is between 200 to 3000mm.
The outer surface of described band also is provided with stiffening rib, can form spiral pipe.
Be provided with reinforcing line in the described extruding pipe, improve the rigidity of extruding pipe.
The beneficial effects of the utility model are: the utility model twines one deck band by the outer wall at extruding pipe and forms multiple tube, than existing entwining tube easy-formation more, reduced cost of production, rigidity and circularity after twining simultaneously are better, are more suitable for making the drainage pipe of major diameter (more than 1 meter).

Among the figure: 1 extruding pipe, 2 entwining tube, 21 bands, 22 cavitys, 23 steel band stiffening ribs, 3 weld seams.
Embodiment
As shown in Figures 1 to 4,
A kind of composite drainage pipe, the multiple tube that is formed by extruding pipe 1 and the outer field entwining tube 2 of internal layer.Extruding pipe 1 wherein is the PE tubing of integral extrusion moulding, can increase reinforcing line in the process of extruding and moulding in extruding pipe, and reinforcing line can arrange vertically, but also screw arrangement, such as steel cord, cotton rope etc.The wall thickness of extruding pipe 1 can satisfy intensity between 3 to 10mm uses.PE tubing herein is matrix, can be used as skeleton and uses, and is convenient to the carrying out of winding working procedure.Entwining tube 2 is to twine and overlap hot weld by band to form at the outer surface of extruding pipe, from the outside, is helical, and weld seam 3 is arranged.Band 21 is extruding and moulding, is evenly equipped with some cavitys 22 in the cross section of band, and is provided with steel band stiffening rib 23 in the both sides of cavity.Further, also be provided with stiffening rib at the outer surface of band, can further increase whole intensity by stiffening rib.
By the drainage pipe that such scheme is produced, its diameter can satisfy the Production requirement of large-diameter pipeline between 200 to 3000mm.
Except the described technical characteristics of specification, be the known technology of those skilled in the art.
Claims (6)
