Abstract
The utility model relates to a steel-plastic composite winding pipe adopting a door-shaped steel belt, which comprises the door-shaped steel belt, a pipe blank and a cladding wall and is characterized in that the cladding wall is arranged outside the pipe blank, the door-shaped steel belt of which an opening is located towards the inner wall of the pipe is fixed between the pipe blank and the cladding wall, and structures formed into a whole through hot melting are wound between the pipe blank and the cladding wall in a spaced manner. The steel-plastic composite winding pipe overcomes the defects in the prior art; force-bearing points of a formed pipeline are relatively dispersive, which greatly lowers the probabilities that a steel-plastic combined surface is stripped and the structures of the winding pipe are damaged; as polyethylene of the pipeline cannot be damaged, steel and plastics can be firmly connected together, thereby effectively realizing that the steel belt cannot be easily corroded in the coating of the polyethylene, maintaining the strength of the polyethylene winding pipe and ensuring the completeness of the entire structure of the polyethylene winding pipe under the condition of pipe embedding; the steel-plastic composite winding pipe cannot cause pollution to the underground environment after being used for a long time; compared with a steel-plastic water drainage pipe with dual flat walls, the steel-plastic composite winding pipe saves metal materials by 50% and reduces the production cost by over 40%.
Description
Technical field
The utility model steel plastic composite wound pipe of door shape steel band, what relate to is plastic tube design, processing technique field, is applied to underground buried tube.
Background technique
Domestic, plastic tube, especially heavy caliber polyethylene wound pipe material, according to properties of materials as can be known, poly Young's modulus is less, its tubing, especially the ring stiffness of heavy caliber pipe is less relatively, imbeds underground, special in the area that often is subjected to weight, tubing ftractures easily, behind the tubing cracking, because imbed underground, be difficult in time be found, long seepage, ground water will be subjected to pollute even severe contamination, use this type of tubing, be subjected to environmental administration and broad masses' query; The intensity that steel band, reinforcing bar increase heavy caliber pipe is set up in the employing that also has outside entwining tube, though temporarily increased ring stiffness, be embedded in underground after, corrosion very gets rusty easily, soon with regard to the corrosion of invar band, reinforcing bar, and the original intention of losing the increase ring stiffness, moreover, owing to structural reason, example: the technological scheme of patent 200820064736.5, its intensity is good, but its difficulty of processing is big, and the metallic material waste is serious; To form entwining tube antirust for by spraying 0.15-0.25mm thick plastic layer on steel band again, because up to standard difficult during pretreatment, or because plastic layer is scratched, often rate of corrosion is faster under the situation of water logging, the steel band that increases does not just have use value as illusory at all.
The model utility content
The purpose of this utility model is to overcome above-mentioned defective, and the structure of setting up steel band in the polyethylene wound pipe material is reformed, and particularly two flat walls steel plastic strip water pipe is improved, and reaches the steel plastic composite wound pipe with door shape steel band that saves material.Its technology is: the structure that comprises a shape steel band, pipe, coating wall, it is characterized in that: pipe is provided with the coating wall outward, be fixed with opening between pipe and the coating wall and twine hot melt all-in-one-piece structure towards the door shape steel band and the interval of inner tube wall, described door shape steel band sectional shape can be square or rectangular.The positive effect of implementing after this technology is: at first overcome above-mentioned defective, the force bearing point of the pipeline that forms disperses relatively, making steel mould junction plane peels off, the possibility that the structure of wrapped tube is damaged greatly reduces, because the polyethylene of pipeline can be not damaged, thereby having guaranteed that steel is moulded securely is connected together, realize that effectively steel band is difficult to be corroded in the polyethylene parcel, kept polyethylene wound pipe material intensity, can be under the situation of pipe laying the polyethylene wound pipe material integrally-built complete, the long-term use can not pollute underground environment, compares two flat walls steel plastic strip water pipe, save metallic material 50%, reduce production costs more than 40%.
Description of drawings
Fig. 1 is a structural representation of the present utility model,
Wherein, 1-pipe, 2-door shape steel band, 3-coat wall;
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
See accompanying drawing 1, pipe 1 outer being provided with coats wall 3, is fixed with opening between pipe 1 and the coating wall 3 and also twines hot melt all-in-one-piece structure at interval towards the door shape steel band 2 of inner tube wall, and door shape steel band 2 is rectangle.
See accompanying drawing 1, at first sheet metal is sheared slivering by the spreading width size of door shape steel band 2, the steel band of shearing slivering enters brake and is pressed into the door shape steel band 2 of cross section for door shape; Extruder is extruded the pipe 1 of HDPE band shape, through traction, door shape steel band 2, pipe 1 enter the extruder main frame from direction separately, after door shape steel band 2 enters pipe 1 set coating wall 3 positions, by extruder main frame, spiral winding machine and corresponding slave drive, the door shape steel band 2 outer walls 3 that coat, pipe 1 and 3 weldings of coating wall, the three is twined simultaneously and is fused into one, forms steel plastic composite wound pipe, again through shaping, typing, cool off, cut into the steel-plastic composite pipe of the specification length of dispatching from the factory.
Claims (2)
1. with a steel plastic composite wound pipe of shape steel band, the structure that comprises a shape steel band, pipe, coating wall, it is characterized in that: pipe is provided with the coating wall outward, is fixed with opening between pipe and the coating wall and twines hot melt all-in-one-piece structure towards the door shape steel band and the interval of inner tube wall.
2. the steel plastic composite wound pipe with door shape steel band according to claim 1 is characterized in that: door shape steel band sectional shape can be square or rectangular.
