As center of technical means of communication network, integrated wiring system is closely related to housing, computer network and other systems. Therefore, when developing technical solutions for various types of integrated wiring systems, in addition to communication networks, computer networks and building automation systems, it is also necessary to take into account ways of interacting with housing construction and other related issues.
When planning, contractor must fully understand and master its usage characteristics, technical functions and development trends, carefully analyze and study to select technologically advanced, economically sound and feasible solutions, so that architectural design and construction technology can be closely related to cooperate.
The laying of all cables and installation of equipment in a complex electrical wiring system require special rooms, hidden pipes and channels buried in cable shafts, reserved grooves and openings for wires, etc. These fixed structures are designed and implemented simultaneously as construction of a building. Construction should cooperate closely with competent departments of building and other pipeline facilities, coordinate with each other and consolidate main functions of building and communication quality of integrated wiring system.
Pipe insertion precautions
The link between smart building and outside world is usually connected to public network and run from outside to inside of building. Communication lines connected to public network, trunk cables and building group optical cables are also trunk lines connected to external integrated wiring system. The number of cable pairs or number of cores of optical cable of lines are many, which is key to maintaining smooth communication.
The method of laying these communication lines must be introduced into building through underground pipelines to ensure safe and reliable communication and ease of maintenance and management. In this regard, when designing and building an integrated electrical wiring system, it is necessary to closely contact design and construction departments to coordinate and solve following problems.
Injection site must match structure of house
The routing and location of underground pipelines outside houses and buildings should follow consideration of communication lines when planning city streets, security engineering structures or smart communities. The route and location of underground pipelines introduced into smart buildings should depend on factors such as design and layout of building, location of control room, location of building's junction box, and presence of negative impacts on other objects. pipelines. .
Pipeline routing should be as direct as possible
The incoming piping route should be as straight as possible to reduce bending and twisting, safe and secure, and best run close to terminal building distribution frame and vertical cable shaft (or lifting piping, lifting cable trough). ) as far as possible Stay away from all kinds of pipelines that compromise security of communication lines. If this cannot be avoided, isolation or protection measures should be taken, if inlet of underground pipeline is under high pressure, then technical scheme can be changed or a different route and location can be chosen, and it is also recommended to use a pipe with reinforced concrete lintel or an inlet pipe. Only steel pipes are used pipes and more.
Must provide holes for waterproof plug
The number of pipe holes (including inner diameter of pipe holes) or size of reserved holes should be reserved for future development. More importantly, housing unit must take waterproof and moisture-proof technical measures around pipes or openings. Free pipe openings or reserved openings must be sealed with waterproof materials and cement mortar to prevent contamination and moisture ingress.
Simultaneous construction of pipelines and buildings
Inlet pipes or standby openings must be constructed at same time as construction of building to achieve efficiency and structural integrity. It is best to lay inlet pipes and underground pipes outside house at same time. . To facilitate construction connection and subsequent maintenance, manholes and inspection hatches should be provided at junctions between external underground pipes and inlet pipes, as a boundary between internal and external structures.
