Problems solved by technology

In addition, since the flanges are connected with each other through the filler, the water resistance and pressure resistance of this part to the outside are limited, and the screw and nut are required to be tightened evenly, which also limits the improvement of work efficiency.

Abstract

The invention provides a connection structure of waveform plastic conduit, a waveform plastic conduit used by the connection structure and manufacture method thereof. A tubular insertion part (3) is set on the opposite end (10) of a first waveform plastic conduit (1A) by covering at least burying the synthetic resin layer (5) for forming the waveform cove (2a) of the end outer-surface side. A pipesocket part (4) is set on the opposite end (11) of a second waveform plastic conduit (1B) and composed of synthetic resin, which is covered on the end outer-surface side and extends in outside tubular shape along the axle direction and the tubular insertion part (3) of the first waveform plastic conduit (1A) is inserted into the pipe socket part (4) of the second waveform plastic conduit (1B) andconnected with each other.

Description

technical field [0001] The present invention relates to a corrugated synthetic resin pipe whose wall is formed into a spiral corrugation, and which is used, for example, as a drainage pipe under roads and a sewer pipe, and a manufacturing method thereof. Background technique [0002] In the past, Hume tubes made of concrete were generally used as drainage lines under roads and sewers, but in recent years, Hume tubes have been used as strengths equal to or higher than Hume tubes, durability, weight reduction, and labor-saving construction. A corrugated synthetic resin tube which is advantageous in terms of the invention uses a tube in which a spiral-shaped reinforcing convex portion is provided on the outer peripheral side of a main body portion whose inner surface is substantially flat. When connecting a plurality of such corrugated synthetic resin pipes, the following structure is adopted, and a split joint with a connecting flange provided with a packing sheet (packing she...
