Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] The connector structure that the present invention adopts is as attached figure 1 As shown, it includes a first straight section 31 with a smaller diameter and a second straight section 32 with a larger diameter, and a trumpet-shaped connecting section 33 is connected between the first straight section 31 and the second straight section 32 , the thickness of the connecting section 33 is greater than the thickness of the two straight sections, and the ports of the two straight sections are provided with chamfers 34 for easy installation.

[0024] The implementation process of the present invention is as attached figure 2 As shown, first use the double-wall corrugated pipe 1 and another double-wall corrugated pipe as the connecting pipe 5 to clean the surface debris. Install the sealing ring 4 to the first peak groove of the socket of the bellows 1 and the conn...

Abstract

The invention provides a connection method of double-wall corrugated pipes. The method realizes the connection between two double-wall corrugated pipes through a hollow connecting piece. Two ports ofthe connecting piece respectively correspond to the connection segments of the double-wall corrugated pipes, the inner diameter of the port of the connecting piece is slightly more than the outer diameter of the connection segment of the corresponding double-wall corrugated pipe and the double-wall corrugated pipe is inserted and connected in the connecting piece. The method effectively realizes the connection between two double-wall corrugated pipes, especially the pipes of different materials.

Description

technical field [0001] The invention belongs to the technical field of pipe connection, in particular to a connection method between large-diameter double-wall corrugated pipes. Background technique [0002] In the field of plastic pipeline engineering installation, inspection well transition connection is usually used in the design and application of drainage engineering. When corrugated pipes of different materials and specifications appear, if the connection methods commonly used for the two pipe materials are used for connection, the experiment proves that it is currently impossible to connect. . The use of rubber sealing rings to connect has the problem of different production sizes. For example, if the socket of HDPE double-wall corrugated pipe is used, the size of the socket is too large; if PVC-U special adhesive is used, it is even more unfeasible, and different materials cannot be welded. [0003] Under the condition that the inner diameter deviation of the produc...
