Detachable seven-hole cellular tube

Abstract

The invention belongs to auxiliary equipment of communication, and relates to a detachable seven-hole cellular tube. The detachable seven-hole cellular tube comprises packaged sub-tubes, concave troughs, convex troughs, a locking fastener and a snapping fastener. The tube wall of each hexagonal sub-tube is provided with concave trough and convex troughs which are arranged alternatively. Two paired edges of the sub-tube are provided with longitudinal openings which are fixed by the snapping fastener. After seven sub-tubes are tightly inserted through the concave troughs and the convex troughs, the seven-hole cellular tube is formed. A locking fastener which is fixed by the snapping fastener is arranged outside the seven-hole cellular tube. The tube wall of the hexagonal sub-tube is provided with the concave troughs and the convex troughs. After the seven sub-tubes approach one another, the seven-hole cellular tube is formed. The locking fastener which is fixed by the snapping fastener is arranged outside the seven-hole cellular tube. The detachable seven-hole cellular tube has advantages of simple structure, low cost, unchangeable integral stability and pressure resistance, unchanged number of optical cables which can be accommodated, detachment of the sub-tubes, etc.

Description

technical field [0001] The invention belongs to communication auxiliary equipment and relates to a detachable seven-hole honeycomb pipe. Background technique [0002] Due to external factors or the optical fiber itself, etc., the optical cable line failure will occur. The service interruption caused by the failure of the optical cable line is long and affects a wide range of business areas, which is the key link in the security work. In order to make the optical cable communication system work normally, in addition to careful design, careful construction, and normal maintenance, once an optical cable failure occurs, it must be repaired in time to ensure the smooth flow of the line and shorten the failure time as much as possible. [0003] The seven-hole honeycomb tube is a kind of communication pipe that protects the optical cable outside the optical cable. The current seven-hole honeycomb pipe is a honeycomb plastic pipe composed of seven hexagonal small holes. The cross-...

AI Technical Summary

Problems solved by technology

However, since the current seven-hole honeycomb pipe cannot be disassembled and replaced with a new honeycomb pipe, after the repair of the optical cable is completed, the method of directly burying the optical cable or repairing a communication well at the repair point is often used for follow-up processing

If it is directly buried, it will cause the outer layer of this section of optical cable to be unprotected after being buried, and it is prone to failure again; if only the optical cable of a few sub-holes in the seven-hole honeycomb tube is cut off, after the rush repair is completed, if you want to replace it with a new honeycomb To protect the outer layer of the honeycomb tube, all the optical cables on the honeycomb tube need to be cut over, which will cause large-scale service interruption and affect the communication quality

Generally, no secondary excavation will be carried out after direct landfilling. If this section of optical cable has problems again, it cannot be used. Only a new section of optical cable can be built, which will increase the cost.

Similarly, the method of laying wells at the emergency repair point will also increase the repair cost
