Underground communication optical cable trench

Abstract

The invention discloses an underground communication optical cable trench. A precast reinforced concrete pipe groove and a cover plate are matched to form a laying channel extending laterally. Multiple laying channels are communicated with one another and in butt joint. Communication cables are fixedly located on the inner walls of the precast reinforced concrete pipe grooves. An operation channel for people to pass is reserved in the middle of the precast reinforced concrete pipe grooves, which makes it easy for an operator to pass for renovation and extension. The laying channels with greater inner diameter can accommodate more communication cables, have greater accommodating capacity, and provide ample space for later renovation and extension. The precast reinforced concrete pipe grooves are provided with through water outlets at the bottom. Branch holes are arranged in the side walls of the precast reinforced concrete pipe grooves according to actual needs, the communication cables can be connected to the outside through the branch holes, and bifurcation and connection of the communication cables are facilitated. Branch hole positions can be reserved according to the actual needs, the position layout of the branch holes is flexible, and the degree of freedom of line distribution is improved.

Description

technical field [0001] The invention relates to the technical field of optical cable laying, and further relates to an underground communication optical cable trench. Background technique [0002] According to the requirements of urban construction, outdoor communication facilities must be constructed in a concealed way. Generally, underground pipelines or underground direct burial methods are used. In order to ensure the safety of communication facilities, optical cables are mostly laid in underground communication pipelines, which not only meets the needs of communication services, It does not affect the appearance of the city. [0003] At present, most of the traditional optical cable laying methods use single-hole or porous plastic pipes, and each section of the pipe is connected through manholes to form an underground communication pipe. With the rapid development of , transformation and informatization, the number of new construction, reconstruction and expansion proj...

Problems solved by technology

[0003] At present, most of the traditional optical cable laying methods use single-hole or porous plastic pipes, and each section of the pipe is connected through manholes to form an underground communication pipe. With the rapid development of , transformation and informatization, the number of new construction, reconstruction and expansion projects of communication optical cable lines is increasing, and the demand for optical cables is increasing. The capacity of ordinary communication pipelines can no longer meet the needs of a large number of cables and line transformation.
