Setting Of Manholes For Underground Integrated Communication Pipelines

There are three ways to set up manholes. (1) Each pipeline unit sets up Stainless Steel Concentric & Eccentric Reducer independently. It is good if each pipeline unit of underground integrated communication pipeline can set up manholes independently. It is not only convenient for construction and maintenance, but also avoids the interlacing of pipelines in the manholes. However, the result is that too many manholes are set up within a limited range on the sidewalk and the investment is too large, which is not conducive to urban planning and development. It may even cause the idleness of underground pipeline resources and the sedimentation of construction funds, affecting the sustainable development of enterprises. (2) Manholes are set up for the same type of cable business. According to the different business operations of each pipeline unit, manholes can be set up for the same type of cable business. For example, long-line and telecommunications or long-line and China Netcom can set up manholes together to facilitate the connection and continuation of communication business. Companies that mainly use optical cable transmission can consider setting up manholes together or building manholes alone. Public security networks are generally used for electronic monitoring of traffic order. Its transmission medium is mainly optical cable. Generally, manholes should be set up around intersections or on both sides of T-junctions. It is better to set up manholes alone, or they can be set up together with companies that have optical cable transmission. (3) A manhole is set up for different types of cables (electrical cables and optical cables). In this way, due to the obvious difference in the outer diameters of the electric and optical cables, they are not easily misplaced, and can be easily fixed and coiled on the inner wall of the manhole and connected.
