Embodiment Construction

[0018] The construction method of overhead micro-pipe that the present invention proposes, its construction schematic diagram is as figure 1 shown, including the following steps:

[0019] (1) hang steel strand 5 between two utility poles 2, pulley 3 is set on steel strand, a plurality of hooks 4 are set between adjacent two pulleys;

[0020] (2) Pull out the optical cable sub-tube 6 from the optical cable sub-tube reel 1 with the traction rope 7, so that the optical cable sub-tube 6 passes through the pulley 3 and then penetrates into the hook 4 on the steel strand;

[0021] (3) pull the traction rope 7, so that the optical cable sub-tube 6 is erected between the utility poles 2;

[0022] (4) The microcable is blown into the microtube 8 of the subtube 6 of the aerial optical cable by means of air blowing.

[0023] In the above method, the optical cable sub-tube can be a bundle tube, and the bundle tube is provided with 3-4 microtubes, such as figure 2 shown.

Abstract

The invention relates to a construction method for an overhead micro-pipeline and belongs to the technical field of cable transmission. At first, a steel stranded wire is hung between two wire poles; pulleys are arranged on the steel stranded wire; a plurality of hooks are arranged between two neighboring pulleys; a cable sub-pipe is drew out from a cable sub-pipe disc by a drag rope, thus leading the cable sub-pipe to pass through the pulleys and then penetrate into the hooks on the steel stranded wire in sequence; the drag rope is pulled to lead the cable sub-pipe to be spanned between the wire poles; an air blowing method is adopted to blow a micro cable into the micro pipe of the overhead cable sub-pipe. The construction method can be used for mounting the communication cable circuits in villages and towns, fields and sharp terrains and rivers, and leads the network dilatancy advantages to be remarkable; when repairing the cable, the construction method is easy in overhauling and is quick in resuming communication.

Description

technical field [0001] The invention relates to a construction method of an overhead micropipe, which belongs to the technical field of optical cable transmission. Background technique [0002] In the construction of the traditional overhead optical (electrical) cable transmission network, firstly, the pole road is erected on the roadside of urban and rural roads or in the field, and then the optical (electrical) cable is suspended on the existing wire by means of hanging steel cables or its own tensile elements. On poles and towers, due to the heavy weight of ordinary optical (electrical) cables, each optical cable suspension wire is only allowed to hang one optical (electrical) cable, and the utilization rate is low. [0003] Due to the large span of the original overhead optical cable across the river, it is extremely vulnerable to damage from wind, hail, ice and snow, has a high failure rate, and is difficult to repair. [0004] As fixed network operators "light into co...
