Abstract
The utility model relates to a reinforced double-wall corrugated pipe in which the strength between a double-wall corrugated pipe body and a flared opening is increased, wherein concave-convex annular reinforcement ribs are arranged inside the flared opening of the double-wall corrugated pipe, and the junction of the double-wall corrugated pipe body and the flared opening has concave-convex structure. The utility model has the advantage that the strength of connection between the flared opening and the pipe body is increased and the reliability of connection between two double-wall corrugated pipes is improved.
Description
Technical field
The utility model relates to a kind of enhancement mode double-wall corrugated pipe that strengthens intensity between double-wall corrugated pipe pipe shaft and the enlarging, belongs to bellows and makes the field.
Background technique
All notice of authorization CN201166200Y of this China invites the person, title " double-wall corrugated pipe ", it comprises bellows, and described bellows is a double-wall corrugated pipe, and the enlarging circle in the enlarging of its double-wall corrugated pipe is the lenticular ring stiffener of step.Its a fly in the ointment: the insufficient strength of double-wall corrugated pipe pipe shaft and enlarging joint is strong.
Summary of the invention
Purpose of design: avoid the deficiency in the background technique, design a kind of enhancement mode double-wall corrugated pipe that strengthens intensity between double-wall corrugated pipe pipe shaft and the enlarging.
Design proposal: in order to realize above-mentioned purpose of design.The arc joint of double-wall corrugated pipe pipe shaft and enlarging is the design of concaveconvex structure, is major character of the present utility model.The purpose of doing like this is: the arc joint of double-wall corrugated pipe pipe shaft and enlarging is concaveconvex structure, be equipped with stiffening rib just as arc joint in double-wall corrugated pipe pipe shaft and enlarging, this stiffening rib not only can improve the intensity that double wall pipe is accepted enlarging and pipe shaft when connecting effectively, and greatly improved the reliability that is connected between double wall pipe and the double wall pipe.
Technological scheme: the enhancement mode double-wall corrugated pipe, the enlarging circle in the enlarging of double-wall corrugated pipe is the lenticular ring stiffener of step, and the arc joint of described double-wall corrugated pipe pipe shaft and enlarging is concaveconvex structure.
The utility model is compared with background technique, not only improved the join strength between double-wall bellow flare and the pipe shaft, and has improved the reliability that is connected between double wall pipe and the double wall pipe.
Description of drawings
Fig. 1 is the sectional structure schematic representation of enhancement mode bellows.
Embodiment
Embodiment 1: with reference to accompanying drawing 1.The enhancement mode double-wall corrugated pipe, the enlarging circle 4 in the enlarging 3 of double-wall corrugated pipe 1 is the lenticular ring stiffener of step, and the arc joint 2 of described double-wall corrugated pipe 1 pipe shaft and enlarging 3 is concaveconvex structure.Described enlarging 3 outer walls are that black PE material, inwall are blue PE material, and the preparation process of its enhancement mode double-wall corrugated pipe is a prior art, is not described herein at this.
What need understand is: though the foregoing description is to the mentality of designing of the present utility model detailed explanatory note of contrasting; but these explanatory notes; it is simple text explanation to the utility model mentality of designing; rather than to the restriction of the utility model mentality of designing; any innovation and creation that do not exceed the utility model mentality of designing all fall in the protection domain of the present utility model.
Claims (1)
1. enhancement mode double-wall corrugated pipe, the enlarging circle (4) in the enlarging (3) of double-wall corrugated pipe (1) is the lenticular ring stiffener of step, it is characterized in that: the arc joint (2) of described double-wall corrugated pipe (1) pipe shaft and enlarging (3) is concaveconvex structure.
