Abstract
A double-wall twined plastic pipe, which is formed of plastic twisted and welt by hot binding for plastic, is plastic pipe with hollow rectangles, on whose side wall a piece of reinforced protecting film is coated. The cross-section structure in radial direction contains central plastic pipe layer, outer and inner reinforced protecting layers. The cross-section structure in axis direction contains hollow-rectangles plastic pipe, plastic pipe coated by multi reinforced protecting films outside of hollow-rectangles plastic pipe wall and plastic hot binding bonding layers among adjacent plastic pipe coated by reinforced protecting films. The ability against internal and external pressures of the pipe in the invention is strong, internal and external wall is smooth and water resistance coefficient to inner wall of pipe is low. Flow rate and velocity of water are improved and the phenomenon of pipe blocking or creeping generated by corruption of oiliness material or friction of sand each other is prevented. Operating life is improved efficiently.
Description
Technical field
The present invention relates to a kind of plastic pipe, relate in particular to a kind of double-wall winding plastic drain-pipe.
Background technology
At present, the plastic drain-pipe that uses in engineerings such as urban construction mainly contains double-wall corrugated pipe and binary wall twisting and pipe.Because the inner-walls of duct of plastic drain-pipe suffers the corrosion of oily matter in long draining or feedwater process, and the mutual friction mutually of sandstone etc. in inner-walls of duct and the water, make inner-walls of duct pothole or perforation infiltration occur, cause inner-walls of duct water resistance coefficient to become big and flow and flow velocity reduction water, the serious pipeline obstruction that causes, shorten application life, in case pipeline obstruction or pipe perforation infiltration, its pipe-line maintenance expense is high.
Summary of the invention
Purpose of the present invention provides a kind of double-wall winding plastic drain-pipe with new structure for the problems referred to above that overcome the prior art existence exactly.
The object of the present invention is achieved like this: a kind of double-wall winding plastic drain-pipe, be welded through winding and with the plastic hot melten gel by plastic pipe, described plastic pipe is the hollow, rectangular plastic pipe, is coated with one deck at the outer wall of this hollow, rectangular plastic pipe and strengthens protective film; The radially section structure of described plastic drain-pipe comprises middle part plastic pipe layer, outer protective film and the internal layer enhancing protective film of strengthening; The axial section structure of described plastic drain-pipe comprises a plurality of enhancing diaphragm coating plastic bodys of being made up of hollow, rectangular plastic pipe and the enhancing protective film that is coated on the hollow, rectangular plastic tube outer wall, and is connected the plastic hot melten gel articulamentum between each adjacent enhancing diaphragm coating plastic body.
The used material of described enhancing diaphragm is to mix with polyethylene, polypropylene and have the material that strengthens protective effect.
The used material of described enhancing protective film is the modified ultra-high molecular polyethylene.
The thickness of described enhancing protective film is for strengthening 5%～25% of diaphragm coating plastic body pipe thickness.
The thickness of described enhancing protective film is for strengthening 10%～15% of diaphragm coating plastic body pipe thickness.
The present invention strengthens diaphragm owing to the outer wall at plastic pipe has coated one deck, and the inside and outside wall at pipeline after being wound in pipeline forms one deck enhancing protective film respectively, makes the ability of external pressure in the pipeline opposing obtain reinforcement greatly; And improved the slickness of inner and outer walls of pipeline effectively, improved the presentation quality of tubing, reduced the water resistance coefficient of inner-walls of duct, the flow and the flow velocity of water have been improved, prevented from the phenomenon of pipeline obstruction or pipe perforation infiltration to occur, improved application life effectively because of the corrosion of long oily matter or with the mutual friction mutually of sandstone.
