Anti-termite micro-cable for expressway and manufacturing method thereof

Abstract

The invention provides an anti-termite micro-cable for an expressway, relates to the technical field of manufacturing of anti-termite micro-cables for expressways, and solves the technical problem that a common GYTSO4 optical cable and a conventional blowing micro-cable are not high in tensile strength, lateral pressure resistance and termite resistance. The anti-termite micro-cable for the expressway comprises a cable core, tearing ropes, water blocking yarns, a reinforcing pad, a cushion layer, an inner sheath layer and an outer sheath layer. The anti-termite micro-cable for the expressway can be applied to a newly-built expressway communication pipeline system, the utilization rate of the expressway communication pipeline can be effectively increased, the possibility of damaging the optical cable in the construction process can be reduced as much as possible, fault maintenance of the optical cable line by the operator is reduced, and the investment cost is reduced.

Description

technical field [0001] The invention relates to the technical field of manufacturing an ant-proof microcable for expressways, in particular to an ant-proof microcable for expressways and a manufacturing method thereof. Background technique [0002] When the communication optical cable is laid by air blowing, special personnel must be provided at both ends of the pipeline to protect and maintain communication; the protective personnel should also prepare a reel for the blown optical cable; Under the premise of pipe hole diameter and air blowing method of laying, the number of cores is relatively small, which cannot meet the requirements of the network communication system of expressways; for conventional air blowing micro cables, its tensile and lateral pressure resistance performance is difficult to cope with during construction Possible dragging or trampling accidents.

Problems solved by technology

[0002] When the communication optical cable is laid by air blowing, special personnel must be provided at both ends of the pipeline to protect and maintain communication; the protective personnel should also prepare a reel for the blown optical cable; Under the premise of pipe hole diameter and air blowing method of laying, the number of cores is relatively small, which cannot meet the requirements of the network communication system of expressways; for conventional air blowing micro cables, its tensile and lateral pressure resistance performance is difficult to cope with during construction Possible dragging or trampling accidents

When the communication optical cable is constructed by the traction method, it is necessary to select the appropriate cloth to put into the hole. Generally, the optical cable in construction is longer, and the laying procedure is laid from the middle to both sides; all the pipes must be cleaned before laying the optical cable; When laying in the same way, the tensile performance of conventional air-blown microcables will be affected

[0003] In addition, ants are very easy to appear along the expressway. Conventional optical cables are not enough to resist the bites of ants for a long time and are easily damaged.
