Square corrugated pipeline for cable comprehensive pipe gallery, and connecting mode thereof

Abstract

The invention provides a square corrugated pipeline for a cable comprehensive pipe gallery, and a connecting mode thereof. The square corrugated pipeline for the cable comprehensive pipe gallery comprises a hollow cuboid-shaped pipe section (10), an annular cylinder pipe section (20), an annular cylinder bell mouth (4) and an annular cylinder inserting opening (5), wherein a connecting piece comprises a bush (1), an inserting ring (2), hydrophilic non-woven fabric (3), the annular cylinder bell mouth (4), the annular cylinder inserting opening (5), a clamping ring (6), a water swelling sealingring (7) and a baffle (8), and the connecting modes of the pipeline comprise a bell mouth joint (100) connecting mode, a double-inserting opening bell mouth connecting piece (200) connecting mode, aninserting ring type connecting piece (300) connecting mode (300) and an inserting ring and clamping ring comprehensive connecting piece (400) connecting mode.

Description

technical field [0001] The invention relates to a square corrugated pipe and its connection method, in particular to a square corrugated pipe for a cable comprehensive pipe gallery and its connection method. Background technique [0002] The cable integrated pipe gallery is generally set under the sidewalk, and a work well should be set at a certain distance to facilitate construction, inspection and maintenance. The cable integrated pipe gallery is beneficial to the operation and maintenance of the pipeline. If a pipe with a circular cross section is used for laying, it needs to be fixed with a pipe pillow. There is an interval between the pipes, which cannot make full use of the space of the pipe gallery. The laying of pipe pillows will affect the construction progress, and the circular pipes are prone to Z-shaped displacement during the process of backfilling with coarse sand. Therefore, the present invention designs a square corrugated pipe for cable integrated pipe gal...

AI Technical Summary

Problems solved by technology

The cable integrated pipe gallery is conducive to the operation and maintenance of the pipeline. If the pipe with a circular cross section is used for laying, it needs to be fixed with a pipe pillow. The laying of pipe pillows will affect the construction progress, and the circular pipes are prone to Z-shaped displacement during the process of backfilling with coarse sand

Therefore, the present invention designs a square corrugated pipe for cable integrated pipe gallery and its various connectors such as sockets, insert rings and snap rings, which are used to solve the problems of difficult connection construction, consumable materials and water leakage of square corrugated pipes.
