Installation specifications for weak current pipelines, specific requirements for outdoor weak curre

Refer to the construction manual for the installation and construction of building weak current projects.

The laying specifications of outdoor weak current pipelines have the following aspects:

2.Laying depth: Determine the buried depth of weak current pipelines according to the specific situation, and usually require burial in the ground to protect the pipeline from external damage.

The burial depth should be at least 300mm, and under special circumstances, the soil type, traffic load and other engineering construction requirements should also be considered.

3.Pipe diameter and capacity: According to the number and type of weak telecommunication lines, the diameter and capacity of the pipeline are reasonably selected. Make sure there isn't too much bending or buildup inside the pipe for future maintenance and expansion.

4.Waterproof and moisture-proof measures: Appropriate anti-skin and moisture-proof measures should be taken for outdoor weak current pipelines to avoid moisture seeping into the inside of the pipeline or connecting the head, which will affect the normal operation of the line attack and vertical road. It can be installed with the pipe facing down, reserved waterproof joints or treated with waterproof paint, etc.

5.Crossing and crossing specifications: If weak current pipelines need to cross other facilities or cross road surfaces, walls, etc., they should be designed and constructed according to relevant specifications. In public areas, for example, road traffic safety regulations and technical specifications for municipal engineering need to be observed.

6.Identification and protection: Set appropriate markings on pipelines so that weak current lines can be quickly and accurately located during maintenance and overhaul.

At the same time, for the vulnerable parts, such as passing through underground garages, sidewalks and other places, appropriate protective measures should be taken to avoid damage caused by external forces.

The most important thing is that the laying of weak current pipelines should strictly comply with the relevant national laws and regulations and the requirements of construction project management to ensure that the project is completed safely and reliably, and avoid affecting signal transmission and future maintenance operations. Specific specifications and requirements can be consulted with the local construction department or relevant professional bodies. <>

The Embedded Cable Ductway Code is a guiding standard that must be followed to ensure the safety and reliability of the piping system. Typically, the Embedded Cable Ductway specification includes the following aspects:

The first is the design of the pipes. During the design phase, the diameter and number of pipes must be determined based on the length of the pipe, the depth of burial, and the number of cables. Pipes must be designed with a deep enough overburden to protect pipes and cables from the outside environment.

The second is the selection of pipes. Embedded cable ducts need to be made of corrosion-resistant, durable pipes. Commonly used pipe materials are high-density polyethylene (HDPE), polyvinyl chloride (PVC) and glass fiber reinforced plastic.

The third is the laying of pipelines. Pipeline laying must ensure verticality and horizontality, and a support structure composed of reinforced concrete can be used to ensure the stability and safety of pipeline laying.

The fourth is the connection of pipes. The pipeline must meet the connection requirements, generally using plug-in connection or hot melt connection to ensure the connectivity and stability of the pipeline.

Finally, there is the testing and acceptance of the pipeline. After the pipe is laid, it must be tested and accepted to ensure the safety and reliability of the pipe and cable.

In practical application, the specification of embedded cable ducts also needs to consider other factors, such as geological environment, climatic conditions and ambient noise. Therefore, different factors need to be considered in the development of embedded cable duct specifications to ensure the quality and safety of pipes and cables.

In short, the specification of embedded cable ducts is very important to ensure the reliability of outdoor weak current pipeline systems, and the specifications must be strictly adhered to in terms of pipeline design, selection and dismantling, laying, connection, testing and acceptance. <>
