Blowing microtube or cable is a very common construction method. It is mainly used for laying cables, optical cables and other cables in construction, electric power, communication and other industries. Below we will introduce the construction steps and precautions of blowing optical cable in detail.
Work Preparation
1. Material preparation：Prepare the micropipes, air source equipment, air hoses, connectors and other materials that need to be laid.
2. Construction scheme design：Make a construction plan according to the actual situation, including cable laying path, laying method, etc.
3. Environmental inspection: Check whether there are dangerous objects or obstacles on the construction site to ensure construction safety.
Air Source Preparation
Before blowing the pipe, the air source needs to be prepared. Generally, compressed air can be used as the air source. Ensure the stability of the air source and sufficient air pressure to ensure the smooth progress of the construction.
Laying Microtubes
1. Fix the starting point: First determine the starting point of the microtubules and fix it at the starting point. It can be fixed with clamps or other fixing tools to prevent it from falling off or moving during blowing.
2. Air hose link: Connecting air hose to one end of the microtube, make sure the connection is tight and avoid air leakage. At the same time, it is necessary to ensure that the length of the air pipe is long enough to facilitate the operation of the construction personnel.
3. Construction steps:
(1) Start air source equipment, inject gas into air hose to fill the entire air tube.
(2) According to the predetermined route and direction, the airflow is gradually injected into the microtube.
(3) During the air blowing process, the staff need to pay attention to the position and direction of the micropipe to ensure that it passes through curves, slopes and other terrains smoothly.
(4) During the construction process, the air pressure can be adjusted timely according to the needs to control the advancing speed of the microtubes.
Construction Notes
1. Safety first:During the construction process, the safety of construction personnel must be ensured. Comply with relevant safety operating rules and wear necessary personal protective equipment.
2. Construction quality: To ensure the laying quality of microtubes, avoid problems such as excessive bending, twisting, and flattening, so as not to affect the transmission performance of the cable.
3. Stable air source: It is necessary to ensure the stability of the air source and sufficient air pressure to ensure the smooth progress of the construction.
4. Environmental protection: During the construction process, attention should be paid to protecting the surrounding environment to avoid damage or pollution to surrounding buildings and facilities.
In short, blowing optical cables is a common cable laying construction method. During the construction process, preparatory work is required, and attention should be paid to gas source preparation, micropipe laying steps and construction precautions. Only by doing these things well can we ensure the smooth laying of micropipes and improve construction efficiency and quality.
