Abstract

The utility model provides an enhancement-type plastic ribbing winding pipe comprising a spiral wound U-shaped profiled bar and sol weld joints. Each sol weld joint combines two adjacent sides of the U-shaped profiled bar to form a convex rib. The technical problems of high cost and lower ring stiffness are solved.

Description

A kind of enhanced plastic ribbing entwining tube
Technical field
The utility model relates to municipal pipeline, particularly enhanced plastic ribbing entwining tube.
Background technique
Traditional sewage treatment drainage pipe adopts concrete duct, and this pipeline needs all at the scene construction, the construction inconvenience very of getting up, and construction cost is high, and can not be repeated to utilize, and also be subject to certain restrictions working life.
Based on above-mentioned many defectives, developed into afterwards in order to adopt steel pipe as blow-off line, but had the defective that cost is high, working life is short.
In recent years, along with the wilderness demand to municipal pipeline, and for some technological deficiencies before overcoming, many plastic pipes have appearred, such as pvc pipe, straight-through conduit pipe, enhancement mode helical corrugation entwining tube etc.For pvc pipe and straight-through conduit pipe, its general use does not on the ground need to bear great radial pressure, and is therefore, less demanding to the ring stiffness of tubing.At present, the using scope of enhancement mode ripple entwining tube is very large, use amount is also many, as being to be that open day of 2010.7.6 discloses a kind of overall plastic internal rib reinforcing outer ripple type plastic twining structured wall pipe in the patent documentation of 2010.12.8 201010218818.2 applyings date at application number, comprise that cylndrical surface tubing body and spiral surrounding are at the stiffening rib in the body outside, stiffening rib includes one perpendicular to the enhancing internal-rib of tube wall, and this internal-rib is divided into two hollow cavities arranged side by side with stiffening rib.The defective of its existence is: (1) in forming process, by extruder extrude for two ends with the profile shapes of hollow cavity, then profile shapes is twined and forms tubing by welding; Because extruding and moulding has hollow cavity, for preventing distortion, need to strictly control parameters such as the temperature of extruding and moulding, times, extrusion die also there is strict requirement, thereby causes the cost of extruding high; (2) tubing is embedded to underground after, after stiffening rib was received pressure, owing to have hollow cavity, therefore, deformation occured in stiffening rib easily, thereby affects the ring stiffness of tubing; (3) will form the profile shapes of hollow cavity, its consumptive material is many, and cost is high.
Summary of the invention
For overcoming above-mentioned technical problem, the utility model provides a kind of enhanced plastic ribbing entwining tube.
The technological scheme that solves the problems of the technologies described above is: enhanced plastic ribbing entwining tube comprises U-shaped profile shapes and the colloidal sol weld seam of spiral winding; The colloidal sol weld seam is combined together to form fin with the dual-side of mutually close U-shaped profile shapes.
As further improvement, U-shaped profile shapes cross section comprises bottom and dual-side, and the dual-side inner side edge extends laterally from the bottom.
As further improvement, the top of dual-side is circular arc.
The beneficial effects of the utility model are: because the cross section of U-shaped profile shapes is U-shaped, when the U-shaped profile shapes of extruding and moulding, because cross-sectional structure is simple, even thickness be difficult for to produce bubble and distortion, to temperature, time and the extrusion die of extruding and moulding require low, therefore, it is low to extrude cost.Because cross section is U-shaped, its structure is equivalent to I-steel, and therefore, the strength and stiffness of U-shaped profile shapes are high, can improve the ring stiffness of entwining tube.With respect to prior art, owing to there has not been hollow cavity, reduced the use of material, reduced the cost of raw material.Owing to be U-shaped cross section, be embedded to the depressed part of U-shaped profile shapes when soil layer after, can prevent effectively that entwining tube from moving axially.Because the colloidal sol weld seam is between dual-side, the area of its welding is large, therefore can improve the intensity of entwining tube.Because the dual-side inner side edge extends laterally from the bottom, when the soil layer pressure-acting is to the inner side edge of dual-side, can produce horizontal and vertical component at inner side edge, can reduce radial pressure by inner side edge, so that entwining tube is difficult for occuring radial deformation.Because the top of dual-side is circular arc, can avoid stress to concentrate, improve the intensity of entwining tube.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
As shown in Figures 1 to 4, enhanced plastic ribbing entwining tube twines the colloidal sol welding fabrication by U-shaped profile shapes 1, U-shaped profile shapes 1 cross section comprises bottom 11 and dual-side 12, form depressed part 13 between bottom 11 and the dual-side 12, the colloidal sol welding forms the colloidal sol weld seam between mutually close dual-side 12, and dual-side and colloidal sol weld seam form fin 2; The dual-side inner side edge extends laterally from the bottom; The top 3 of dual-side is circular arc, the phenomenon of concentrating to reduce stress.
The forming method of enhanced plastic ribbing entwining tube of the present utility model is: first by the U-shaped different in nature material of extruder moulding, U-shaped different in nature material is twined, simultaneously, extrude colloidal sol by another extruder, by colloidal sol mutual close U-shaped different in nature material is welded together, and make welding more firm by guide wheel.
In the utility model, because the cross section of U-shaped profile shapes 1 is U-shaped, when the U-shaped profile shapes 1 of extruding and moulding, because cross-sectional structure is simple, even thickness is difficult for producing bubble and distortion, to temperature, time and the extrusion die of extruding and moulding require lowly, therefore, it is low to extrude cost.Because cross section is U-shaped, its structure is equivalent to I-steel, and therefore, the strength and stiffness of U-shaped profile shapes 1 are high, can improve the ring stiffness of entwining tube.With respect to prior art, owing to there has not been hollow cavity, reduced the use of material, reduced the cost of raw material.Owing to be U-shaped cross section, be embedded to the depressed part of U-shaped profile shapes 1 when soil layer after, can prevent effectively that entwining tube from moving axially.Because the colloidal sol weld seam is between dual-side, the area of its welding is large, therefore can improve the intensity of entwining tube.Because the dual-side inner side edge extends laterally from the bottom, when the soil layer pressure-acting is to the inner side edge of dual-side, can produce horizontal and vertical component at inner side edge, can reduce radial pressure by inner side edge, so that entwining tube is difficult for occuring radial deformation.Because the top of dual-side is circular arc, can avoid stress to concentrate, improve the intensity of entwining tube.
