Abstract
The utility model discloses a double-walled corrugated pipe for an underground communication pipeline. The pipe wall of the double-walled corrugated pipe is formed by rolling and the melting and connecting a strip-shaped HDPE (high-density polyethylene) plate strip with a corrugated bulge backbone; an arc-shaped concave-convex structure is arranged at the connection part of a pipe body of the double-walled corrugated pipe and a flaring; a HDPE melt body is coated on a melting part; and a spirally-wound steel wire or a spirally-wound steel belt is enwrapped in the HDPE melt body. With the adoption of the scheme, the overall strength of the pipe body is enhanced, and the double-walled corrugated pipe is simple in structure and is convenient to manufacture. Moreover, the formed enhanced double-walled corrugated pipe has high ring rigidity, thereby not only improving the connection intensity between the flaring of the double-walled corrugated pipe and the pipe body but also improving the reliability of connection of the double-walled pipes.
Description
Technical field
The utility model relates to the tubing equipment and technology, relates in particular to a kind of underground communication pipeline and uses double-wall corrugated pipe.
Background technique
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, underground communication pipeline.No matter present double-wall corrugated pipe is to use PVC or HDPE material, its process equipment double-walled ripple.
Summary of the invention
The purpose of the utility model provides a kind of underground communication pipeline and uses double-wall corrugated pipe, and simple in structure, ring stiffness is strong, easily manufactured with can effectively improve the join strength of bellow flare;
A kind of underground communication pipeline is used double-wall corrugated pipe; Its tube wall is that the strip HDPE strip that has a protruding spine of corrugated rolls then welding each other and forms; Enlarging circle in the enlarging of double-wall corrugated pipe is the lenticular ring stiffener of step, and the arc joint of said double-wall corrugated pipe pipe shaft and enlarging is a concaveconvex structure.
Scribble one deck HDPE melt on the said weld portion.
Be enclosed with steel wire or steel band that spiral twines in the said HDPE melt.
Compared with prior art, the advantage of the utility model is:
The utility model is through being penetrated with axial connecting tendon on outer wall; Increased its integral intensity; And simple in structure, easily manufactured, and the reinforced double-wall corrugated pipe ring stiffness that constitutes is high; Not only improve the join strength between double-wall bellow flare and the pipe shaft, and improved the reliability that is connected between double wall pipe and the double wall pipe.
Description of drawings
Fig. 1 is the structural drawing of the utility model;
Fig. 2 is the utility model weld structural drawing.
Embodiment
The specific embodiment of the utility model; A kind of underground communication pipeline is used double-wall corrugated pipe; Its tube wall is that the strip HDPE strip that has a protruding spine of corrugated rolls mutual welding with helical and forms, and as shown in Figure 1, a kind of underground communication pipeline is used double-wall corrugated pipe; It comprises bellows 1; Described bellows 1 is a double-wall corrugated pipe, and the enlarging circle 7 in the enlarging 3 of double-wall corrugated pipe 1 is the lenticular ring stiffener of step, and the arc joint 2 of said double-wall corrugated pipe 1 pipe shaft and enlarging 3 is a concaveconvex structure.
As shown in Figure 2; Be part shown in the A among Fig. 1, on the weld portion 5 of strip, scribble one deck HDPE melt 4 again, the reinforced double-wall corrugated pipe of the utility model during fabrication; Need not expensive double-wall corrugated pipe forming machine; Only the equipment that need roll rolls strip strip spiral, weld portion 5 is welded together, and then on weld portion 5, is coated with the highly dense HDPE melt 4 of last layer; In order further to improve the ring stiffness of pipe, be enclosed with steel wire 6 or steel band that spiral twines in the HDPE melt 4 on weld portion 5.Get final product after roll extrusion then, the cooling.
The reinforced double-wall corrugated pipe ring stiffness of the utility model can reach SN4-SN8, and comparing existing double-wall corrugated pipe ring stiffness SN2 has the raising than the people.
