Novel detachable seven-hole honeycomb pipe

Abstract

The present invention belongs to a communication auxiliary device, and relates to a novel detachable seven-hole honeycomb pipe. The seven-hole honeycomb pipe comprises subpipes, an opening, cover plates and joint packages. Seven hexagonal subpipes are stacked up to form a honeycomb shape, the outer portions of the hexagonal subpipes are fixed by one joint package at a certain interval, the joint packages are hollow circular columns, and the inner shapes of the joint packages are the same as the subpipes staking together; pipe walls of one sides of the hexagonal subpipes are provided with the opening which is sealed by matching cover plates; and the joint packages are formed by two portion buckled together in the push-and-pull mode. The novel detachable seven-hole honeycomb pipe is simple in structure, low in cost and invariant in the whole stability resistance to pressure and the number of the admissible optical cables, and can dismount and replace the subpipes, etc.

Description

Technical field [0001] The invention belongs to communication auxiliary equipment and relates to a new type of detachable seven-hole honeycomb tube. Background technique [0002] Due to external factors or the optical fiber itself, the optical cable line will fail. The service interruption time caused by fiber optic cable line failure is long, affecting a wide range of business areas, and is a key link in safety work. In order for the optical cable communication system to 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 smooth lines and minimize the failure time. [0003] The seven-hole honeycomb tube is a communication duct that protects the optical cable outside the optical cable. The current seven-hole honeycomb tube is a honeycomb plastic tube composed of seven hexagonal small holes. The cross-section shape is like a honeycomb. It adopts an integrated porous ...

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 cable repair is completed, the method of directly burying the cable or repairing a communication well at the repair point is often used for follow-up processing, which is very costly.

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
