Embodiment Construction

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Apparently, the described embodiments are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.

[0027] see figure 1 as shown, figure 1 It is a structural schematic diagram of an optical cable laying duct in the prior art.

[0028] Taking the construction optical cable 3 in the main pipe 1 with a typical pipe diameter of 90 mm as an example, the sub-pipes 5 are hard PVC plastic pipes, and an optical cable 3 is laid in each sub-pipe 5 . The friction between them is relatively large. In order to facilitate the laying of the optical cable 3, the optical cable 3 accounts for ...

Abstract

The invention provides a flexible casing pipe for optical cable laying and an optical cable laying pipeline. The flexible casing pipe for optical cable laying comprises a pipe body, wherein the pipe body is provided with a channel for an optical cable to pass through, and the pipe body comprises a lubricating layer, a first wear-resistant layer, a waterproof layer and a second wear-resistant layer which are stacked from inside to outside. According to the invention, the problem that an existing pipeline is low in space utilization rate is solved, and then the technical effect of improving the space utilization rate in a main pipe is achieved.

Description

technical field [0001] The application belongs to the technical field of optical cable transmission, and in particular relates to a flexible sleeve for laying an optical cable and a pipe for laying an optical cable. Background technique [0002] The optical cable laying duct includes a main pipe and a sub-pipe, and a plurality of sub-pipes are placed in the main pipe, and the optical cable is laid in the sub-pipe. Before the construction and laying of the optical cable, the sub-tube needs to be pre-placed in the main tube. Generally, manual or machine pulling is used to transfer the sub-tube into the main tube, and then the optical cable is pulled into the sub-tube. Because the sub-tube has a certain hardness, in order to facilitate the threading of the optical cable, the inner diameter of the sub-tube is much larger than the diameter of the optical cable. Due to the large difference in the diameter of the optical cable, the sub-tube cannot change with the diameter of the op...
