Abstract
The utility model discloses a reinforced double-wall corrugated pipe, wherein the pipe wall is fused by bar-shaped high-density polyvinyl boards with projected crests and is coiled into a spiral shape mutually. A layer of high-density polyvinyl fusion is coated on a fusing part of the boards. A device which is coiled by the reinforced double-wall corrugated pipe of the utility model has inexpensive cost, and constituted reinforced double-wall corrugated pipe rings have high rigidity.
Description
Technical field
The utility model relates to the drainage equipment in city, specifically a kind of reinforced double-wall corrugated pipe.
Background technique
Reinforced double-wall corrugated pipe is widely used in the discharging of urban sewage and rainwater and reclaims, and in the pipe networks such as agricultural, chemical industry.No matter present double-wall corrugated pipe is to use PVC or HDPE material, and the double-wall corrugated pipe forming machine of its process equipment is all very expensive.
Summary of the invention
The purpose of this utility model is: provide a kind of manufacturing equipment cheap, the reinforced double-wall corrugated pipe that ring stiffness is high.
The technical solution of the utility model is:
A kind of reinforced double-wall corrugated pipe is characterized in that, its tube wall is that the high density polyethylene (HDPE) strip of the strip spine that has projection rolls mutual welding with helical and forms, and scribbles a hdpe layer melt on the weld portion of strip again.
It is the spine of trapezoidal hollow that the cross section is arranged on the bottom, and strip has the bottom, and the bottom is a weld portion near the position at two ends.
In order further to improve the ring stiffness of pipe, can be enclosed with steel wire or the steel band that spiral twines in the high density polyethylene (HDPE) melt on weld portion.
The beneficial effects of the utility model are: the equipment that rolls is comparatively simple, and the reinforced double-wall corrugated pipe ring stiffness height that constitutes.
Description of drawings
Fig. 1 is the partial schematic sectional view of reinforced double-wall corrugated tube wall of the present utility model.
Fig. 2 is the partial schematic sectional view of another embodiment's of the utility model reinforced double-wall corrugated tube wall.
Wherein, reference character: 1 is weld portion, and 2 is spine, and 3 is the bottom, and 4 is the high density polyethylene (HDPE) melt, and 5 is steel wire.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Specific embodiment of the utility model 1, a kind of reinforced double-wall corrugated pipe, its tube wall is that the strip by strip rolls mutual welding with helical and forms, as shown in Figure 1, on the weld portion 1 of strip, scribble a hdpe layer melt 4 again, strip has bottom 3, and it is the spine 2 of trapezoidal hollow that the cross section is arranged on bottom 3, and bottom 3 is a weld portion 1 near the position at two ends.Reinforced double-wall corrugated pipe of the present utility model during fabrication, need not expensive double-wall corrugated pipe forming machine, only the equipment that need roll rolls strip strip spiral, and weld portion 1 is welded together, and then on weld portion 1, be coated with the highly dense polyethylene melt of last layer 4, get final product after roll extrusion, the cooling.Tube wall upper ridge part 2 adopts the hollow trapezoid cross section, has optimized spine's stress distribution situation, under the prerequisite of the ring stiffness that satisfies pipe, has saved material and has alleviated weight.
Specific embodiment of the utility model 1, a kind of reinforced double-wall corrugated pipe, its tube wall is to roll mutual welding by the strip that strip has a spine with helical to form, as shown in Figure 1, on the weld portion 1 of strip, scribble a hdpe layer melt 4 again, strip has bottom 3, outstanding spine 2 is arranged on bottom 3, bottom 3 is a weld portion 1 near the position at two ends, in order further to improve the ring stiffness of pipe, be enclosed with steel wire 5 or steel band that spiral twines in the high density polyethylene (HDPE) melt 4 on weld portion 1.
Reinforced double-wall corrugated pipe ring stiffness of the present utility model can reach SN4～SN8, compares existing double-wall corrugated pipe ring stiffness SN2 and is greatly improved.
Claims (3)
1. a reinforced double-wall corrugated pipe is characterized in that, its tube wall is that the high density polyethylene (HDPE) strip of the strip spine that has projection rolls mutual welding with helical and forms, and scribbles a hdpe layer melt on the weld portion of strip again.
2. reinforced double-wall corrugated pipe according to claim 1 is characterized in that, is enclosed with steel wire or steel band that spiral twines in the high density polyethylene (HDPE) melt on weld portion.
3. reinforced double-wall corrugated pipe according to claim 1 is characterized in that, it is the spine of trapezoidal hollow that the cross section is arranged on the bottom, and strip has the bottom, and the bottom is a weld portion near the position at two ends.
