Standardizing the installation of MPP cable protection pipes requires a series of steps and precautions to be followed to ensure the quality of installation and the effectiveness of use. Here are the detailed installation specifications:

1. Preliminary preparation

1. Determine the construction location: According to the design requirements and cable direction, determine the installation position of the MPP cable protection pipe.

2. Clean up the construction site: ensure that the construction site is clean and orderly, free of debris and obstacles, and provide good conditions for subsequent construction work.

3. Prepare tools and materials: Obtain the necessary construction tools and equipment, such as hot melt welding machines, electrofusion joints, sealants, sealing rings, brackets, etc., and check whether the quality and quantity of MPP cable protection pipes meet the requirements.

Second, trench excavation

1. Measure and excavate trenches: Excavate trenches of appropriate width and depth according to design requirements and site conditions. The bottom of the trench should be flat and free of debris to ensure the smooth installation of the MPP power pipe.

2. Protecting underground pipelines: Before excavating trenches, underground pipelines and other facilities need to be positioned to avoid injuries and equipment damage caused by improper operation.

3. Pipeline embedding and connection

1. Laying the protective layer: Laying a layer of fine sand or sand at the bottom of the trench, with a thickness of about 10-15cm, is used to protect the MPP cable protection pipe from the uneven pressure of the foundation.

2. Cutting and connecting pipes: Cut the MPP cable protection pipe according to the design requirements, and select the appropriate connection method (such as hot melt connection, electric fusion connection, socket connection, etc.) according to the actual situation. The sealing performance and strength of the connection should be ensured when connecting, so as to avoid the occurrence of water leakage or loosening.

4. Pipeline laying and fixing

1. Smooth laying of pipes: The connected MPP cable protection pipes are laid smoothly in the trench according to the design requirements. Attention should be paid to maintaining the bending radius of the pipeline when laying the pipeline to avoid excessive stress on the pipeline.

2. Fix the pipeline: According to the actual needs, choose the appropriate fixing method (such as bracket, fixing clip, etc.) to fix the pipe in a suitable position to prevent it from moving or sinking.

5. Backfill and acceptance

1. Backfill earthwork: A layer of fine sand or sand, with a thickness of about 10-15cm, is laid above the MPP cable protection pipe to protect the pipe from external pressure. Then the excavated earthwork is backfilled into the trench, and attention should be paid to uniform compaction when backfilling to prevent settlement.

2. Inspection and acceptance: After completing the installation of the MPP cable protection pipe, a comprehensive inspection should be carried out to ensure that the pipeline has no leakage, damage and other problems. After passing the acceptance, the follow-up project construction can be carried out.

Precautions

1. The installation is carried out in strict accordance with the design requirements and construction specifications to ensure the installation quality and service life of the MPP cable protection pipe.

2. Choose the appropriate connection method to ensure the sealing performance and strength of the connection. Care should be taken to prevent contamination and damage to the pipeline during the connection process.

3. In the process of trench excavation and backfill earthwork, attention should be paid to protecting the surrounding buildings, pipelines and vegetation to avoid damage to the environment.

4. Attention should be paid to maintaining the bending radius of the pipeline when laying the pipeline to avoid excessive stress on the pipeline. If necessary, auxiliary facilities such as brackets and supports can be used to fix the pipeline.

By following the above steps and precautions, you can standardize the installation of MPP cable protection pipes to ensure that they can play a good protection effect during use.
